Recently, the well-known rating agencies–quality (Beijing) credit quality assessment Centre Ltd, China quality Association, jointly issued the domestic tire industry quality ratings for BBB, warning color is yellow.
According to reports, the tire quality problems are pads valves and tyre adhesion strength, elongation, strength properties, specify allowable deviation coefficient of friction, as well as tire marks and other irregularities or dissatisfaction.
In recent years, domestic automobile tire product quality, overall healthy upward trend, but increases in General. 2011-sampling quality of automobile tires pass rate above 95%, quality rate was higher, however, tire quality in various regions there are some differences.
Why a valve can affect tire quality rating?
Has over 20 years experience of Ningbo Yinzhou Xinghua Metal Products Factory believes that this is because the valve is small, but they can affect driving safety.

It is understood that the valve when the wheel is rotated, under the influence of centrifugal force deformation, such as 195/70R14 when the tires at 100 km per hour, valve is required to bear some 1.7kg disturbance force if tire driving 50,000 kilometres, valve varies the wheel turning 25 million times.
Most of the Tyre valve rubber products, when the rubber becomes deep red, then its already aging to ensure good air-tightness, so the owners each time when changing tires, must replace the valve.
For more security considerations, at present, the high-end tires are generally in the market have started to use aluminum valves, compared with rubber valves, aluminum can to a large extent this extended time. Even so, owners on the maintenance and repair of valves is also very seriously, because the aging valves and makes the car slow leak, auto grind damage or puncture.
It is understood that the involved people’s livelihood interests of industry quality and credit risk rating, from highest to lowest are divided into four grades a, b, c, d, and each level based on risk scoring are different, classified as AAA, AA, a, BBB, BB, b, CCC, CC, c, d, x-class, and the “+” and “-” fine tuning.

Tire Valve occurs, a compression nut thread pinched the thread damage, transposon bending or valve tube damage effects of gas seal, must be replaced. Tags: vacuum tube valve TR414C bus with air valve

Inner tube 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 the new valve, its embedded flange hole, mounted on the bridge shaped pad, and a spanner nut tightening valve.

(6) fill the wound.

(7) in order to remove or insert valve and cut into the paste in good.

(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. Then the file local and new rubber valve seat ( flange ) coated with glue, and for doing.

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.

Inner tube 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 Tire Valve repair methods are as follows.

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

 If the valve pipe can be repaired, only thread damage, can be a screw tap and a screw thread plate repair.

 ③do not use the valve should be replaced.

 The inner tube through the gaps from inside the valve removal. The inner tube wall without gap, can cut7~8mm export.

 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.

 To fill the wound.

 The will to remove or embedded valve and open hole completion well stick.

⑧when replacing the light car inner tubes 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.
