Copper and natural rubber prices skyrocketing, the Tire Valve core enterprises swallow. The valve core products into the New Year, 5% price increase, but the 2011 copper and natural rubber prices rose about 20 percent, the price performance of the valve core has been far behind in the speed of the main raw material prices. A price adjustment of the valve core is inevitable, expected in late March or early April, the price increase of 5% to 10%.

First, copper and natural rubber at high prices Forced valve core prices. The main raw material of the valve core, copper and rubber, copper accounted for about 60% the cost of the valve core, rubber accounted for about 20% the cost of the valve core. World copper prices since June last year, has jumped more than 60%. In early February this year exceeded $ 100,000 / ton mark, and has been up to new heights. Relative to the beginning of last year, copper prices rose more than 100%, the rubber price increases are more than 100%. Since last year, valve core three price increases, price increase in 15% to 20%, but much lower than the copper and rubber and other raw materials price increase. At current prices, the valve core enterprises are at a loss. The valve core enterprise alone to tap the potential to absorb the cost has been powerless and can only choose to transfer downstream.

Second, the increase in labor costs to promote the valve core prices up. The valve core is labor-intensive industries, labor costs accounted for 20% of the cost of the valve core. Of the valve core enterprises are mainly located in Ningbo, Jiangyin, Shanghai, Hangzhou and Qingdao areas, where relatively high wages. Early last year to implement the new labor contract law, labor costs has been greatly improved. After the Spring Festival this year, the valve core employees wages generally rose one percent to two percent. This valve is also a factor in the mouth, core prices.

Third, the valve core demand to support prices. The valve core is the key auto parts. In 2009 and 2010, China’s auto market growth of the “blowout” This car production in one or two years after 2023 will become consumers of the valve core. Recovery in the world automobile industry, GM, Ford and other world auto giants substantial increase in the sales situation, China’s automobile sales in January to continue to improve, people drive and purchase intention of growth, human security means to increase, which increase the demand on the valve core. provide support for the valve core prices.

The valve core production accounts for 75 percent of world production, half of the valve core in China’s total output controlled by several major manufacturers. The price of these manufacturers has become the benchmark once the prices of other companies quickly followed up. Now the core enterprise of China’s large-scale valve prices intention is obvious, there are individual enterprises has issued notice of price increases. Just consider just mentioned the January price, separated by a short time, so most of the valve core companies consider options at the end of the first quarter or early in the second quarter.

People walk to rely on the legs, car driving reliable four wheel, tire exception, as the legs of a man, before the line will inevitably be difficulties, this time not only brought the travel inconvenience, in the cold or rain and snow prone to accidents.

Often clean up the debris of the tread pattern

Raising seven third repair. “This is each owner should keep in mind the car Cheats. Liu said the winter, the owners best to frequent cleaning of the tread pattern of inclusions inevitably hard debris left in the tire pattern, causing the tire to rupture or discouraged.

To remind owners of the car in motion the process, the tread pattern will inevitably have to mixed gravel and other foreign matter, if not removed, a long time, of which some will own off, but there are a considerable part of more and more “stubborn” stuck in a pattern in the deeper, and when the tire wear to a certain extent, these pebbles may even pierce the casing, a flat tire or even a puncture.

In addition, the owner of the docked vehicles have special attention to avoid Car Tire Valve contact with the outside world a hard object damage, causing the tire deflated. The same time, the owners also often equipped with valve caps to prevent clogged.

Loss of gas in winter puncture culprit

Warned all owners, common in winter puncture the reason most of them are tire loss of gas produced, which is the most easy to overlook one of the reasons for the puncture.

It is understood that the family car at the factory and equipment are the meridian vacuum tire, even in unexpected tie tires, the gas inside the tire will not drain all finished in a short period of time. But the pressure to reduce to a certain extent, the deformation of the tread on both sides will increase once the tread pattern of excessive wear, the carcass will eventually be unable to resist undue pressure and distorted, and finally causing a puncture.

To remind the majority of owners, no matter what time can we ignore the routine maintenance of tires, regularly check the tire bundle nails, cuts, valve rubber aging, cracking phenomenon, discovered should be promptly, to prevent loss of air exercise.

1inner Tire Valve occurs, a compression nut thread pinched the thread damage, transposon bending or valve tube damage effects of gas seal, must be replaced.

Inner tube valve repair methods are as follows.

(1) check flange and inner tube valve adjacent sections have no defects. Such as technical condition is good, and the valve fixed good, should check valve.

(2) if the valve pipe can be repaired, only thread damage, can be a screw tap and a screw thread plate repair.

(3) do not use the valve should be replaced.

(4) from the inner tube through the gap valve inside out. The inner tube wall without gap, can cut7~8mm export.

(5) in the inner tube inside add new valve, its embedded flange hole, mounted on the bridge shaped pad, and a spanner nut tightening valve. Valve bridge pad to be installed, the major axis of the ellipse along the inner circumferential arrayed, rather than horizontal; and must not bend bridge shaped pad, the ends shall be30 °. Bridge shaped pad mounted to the outside, valve should be partially bent sideways toward the inner tube in the direction of.

(7) in order to remove or embedded valve and open hole completion well stick.

(8) when the replacement of light automobile tyre rubber mouth, available to the old knife valve, and silicon carbide grinding wheel in grinding valve tube remaining part, and then in a local and new rubber valve seat ( flange ) parts of glue, and drying.

The new valve is affixed to the ready to place, to make the valve hole accurately and tube hole is consistent, and the valve seat to be embedded inside the inner tube rubber edge. Roller rolling valve seat, and in the specialized curing valve with plate vulcanization.

Valve cap is lost in time after complete valve cap is small, but it can prevent dust, small gravel into the Tire Valve, and the accumulation of dust and grit is likely to top air needle, causing a flat tire, so, check the tires to the attention of owners in the tire on the valve cap is missing, if you lose it to complete as soon as possible.

Parked vehicles to avoid valve damage parked vehicles to avoid tire is too close to the object, if the valve encounters hard objects, the valve is easy to be the root of rim and connections of the rubber tyre split, led.

The new valve is affixed to the ready to place, to make the valve hole accurately and tube hole corresponds with the valve nozzle seat, and the rubber edge to be embedded inside the inner tube. Roll for rolling valve seat, and in the specialized curing valve with plate vulcanization.

Nitrogen permeability tire wall velocity more slowly than air about 30%-40%, tire nitrogen permeability loss is less, the tire pressure can be kept stable for a long time, so that the car can maintain good running condition. They were filled with goods wagons were experimental, filling a nitrogen, the truck can run60000 kilometers.

The many car tire tubeless, if the tire filling air, so the air contained in the moisture will cause the wheel electroplating layer of oxide, and causes the Tire Valve seal is not tight, make the tyre within the gas leak, causing the tire pressure is insufficient. The tires can cause gasoline consumption increase.

According to the United States Department of transportation statistics, the country has 80% about vehicle tires, the resulting increase in oil consumption of 9000000 liters per day. According to the latest statistics, the use of dry nitrogen filling tyre, can reduce fuel2%-10%, and the problems to be solved in chronic deflated tire.

The nitrogen can delay the aging of rubber tyre.

 automobile tire air pressure in the tire of a fear of instability, two afraid of tire rubber aging.

The rubber aging is affected by oxygen molecules in air caused by oxidation. Rubber aging will produce cracking phenomenon, causes the rubber lost due to physical properties, and high purity nitrogen filling the rear tire will be oxidized, thereby prolonging the service life of tire. At the same time because of filling the dry nitrogen gas, but also to protect the rim inner being oxidized.

The Americans had made about the tyre filled with air and nitrogen gas experiment. The experimental results show that the tire statistics, filling nitrogen than filling empty gas running more than26% miles. And nitrogen filled tyre and air inflated tire at the same speed running, the former than latter will run the distance of 1/5, and a nitrogen tire wear is less obvious than that of air inflated tire.

The valve cap is also very important, its main role is to isolate the air, also helps to block dust and debris. Should regularly check the gas nozzle and the nozzle cap is in good condition to ensure that: keep the tire air sealing and prolonging the service life of the tire to maintain the correct tire pressure tire auto valve parts of terms and their definitions of Tire Valve has a core cavity or installation core set of parts components, it directly or through the nozzle seat and the tube or rim connection. The core sleeve has a valve core chamber structure, installed in the absence of core cavity structure on the valve body valve parts nozzle seat valve spud connection nozzle body and mounted on the inner tube or the rim valve parts valve function is for tyre inflation, and maintenance of tyre inflating climate seal.

Every time when changing the tire, will be replaced at the same time auto valve. To do so the cost is very low, but it is to protect the tyres, car and your driving safety is important one annulus. When to buy new tires, please be replaced at the same time. Tire air nozzle and parts that are made of rubber, so it will be with the passage of time and aging. At high speeds, aging, cracking rubber gas nozzle may be because of the centrifugal force and bending, causing leakage. Valve leakage of different tire, very slowly and is not easy to find. Easy to cause the tyre in the low pressure of the traveling case. Bring hidden trouble to driving safety.

Common valve consists of valve body, valve core and the valve cap of three main components.

Tire applications very wide, wide variety, according to the purposes can be broadly divided into: car tires, car tires, truck tires, agricultural tires, engineering tire, special vehicle tire, tire, motorcycle tyres and bicycle tires. One of the most important is the automobile Car Tire Valve. At present, the tire according to the structure can be divided into two categories: bias tire and radial tire, they all belong to the low pressure tire. In general, the tire tyre section width over 17in is a giant tire; tire section width in 17in between 10In and belongs to the large tire; tire section width below 10In tires is a small and medium-sized tires, car tires are generally small and medium-sized tire. In addition, each big tire manufacturers have designed for different types of cars and racing developed for these vehicles for tires, as we all know that F1 racing tires are designed for F1 car development. The following for bias tire and radial tire, tyre with inner tube and tubeless tyre.

In 1, meridian tire: this tire is characterized ply cord arrangement direction and tyre meridian section, as the cord arranged such that the emperor, line strength can be fully utilized, tire cord plies in general than the ordinary diagonal tire can be reduced about40- 50%. Cord in the circumferential direction to contact the rubber alone. Radial tire with common slash births compared, high elasticity, good wear resistance, the service life of the tire can be increased by 30 -50%, small rolling resistance, can reduce the fuel consumption of about 8%, good adhesion performance, good buffering performance, large bearing capacity, the advantages of easy puncture. Disadvantages are: sidewall is easy to split, because the side deformation of large, causing the car to poor lateral stability, technical requirement and high cost of manufacture.

2, tubeless tire: tubeless tires with general tire differs in that there are no inner tube, forcing air directly into the tire, the tire and rim between the need has good seal.

Tubeless tires in appearance and structure with tubeless tires approximation, which is different in tubeless tire wall attached to a thick layer of about 2- 3mm and specially used to seal the sealing rubber layer, which is vulcanized by method of adhesion to, when the tire after perforation, due to its itself is in a state of compression and wrap around needle, so it can be long-term no leakage, even if the puncture objects pull out, also can temporarily maintains the pressure inside the tire.

Tubeless tire bead with a plurality of concentric annular groove, the air pressure in the tire under, groove can reliably make bead tightly on the edge of the rim to ensure sealing. Mounting tubeless tire rim is not flat, it has an inclined bottom and AV paint.Car Tire Valve mouth fixed on the rim, which pad for sealing rubber pad.

Tubeless tyre has good air tightness, good heat radiation, and has the advantages of simple structure, light weight etc.. Disadvantages are en route to repair more difficult. Wide cross section tire: along with the improvement of vehicle speed, reduce vehicle center of gravity, to improve the handling performance, which requires to improve the tire lateral stability and surface adhesion properties, to ensure high speed under the condition of traffic safety, so the low section tyre has become an inevitable trend. Sectional height and section width ratio is representative of tire structure characteristic is an important parameter, called the tire of high aspect ratio, also known as the flattening ratio. From on 20 time begin the century, car tire outside diameter is reduced by 25%, rim diameter is reduced by 35%, tire and rim width nearly doubling, tire of high aspect ratio decreases, car0.5, car0.4, especially wide tires and advanced cars matching, is more elegant.
