If the inner tube valve screw pinch, thread damage, stand under the gland nut bends or valves when the tube is not sealed, you must replace it.
Inner tube valve repair including thread, the method is as follows:
(1) check the ridge and adjacent parts of the inner tube valve with or without defects, such as technology in good condition, and the valve snaps well, valve should be checked.
(2) if the valve pipe thread damage, repair wire tapping tapping threads available.
(3) the unserviceability of the Tire Valve should be replaced.

(4) through the vents to remove valve from the inner tube, inner tube when there is no crack on the wall, you can cut open at the mouth of 7~8mm.
(5) in inner tubes, which put the new valves, to embedding flange hole, install bridge-shaped pad and tighten the valve nut spanners. Valve bridge-shaped mats should be installed, that is along the long axis of the ellipse tubes arranged in a circle, instead of the cross; and not to bend the bridge-shaped mat, his head should be 30 degrees. Bridge pads installed towards the outside, bent part of the valve should be sideways towards the inner tube tube.
(6) fill the wound.
(7) in order to remove or in-line valves and cut into the hole to supplement good.
(8) when replacing diesel light vehicles on the inner tube rubber mouth, free knife when cutting the old valve and silicon carbide grinding wheel on the inner tube valve grinding rest. Then place in the mill and the new rubber valve seat (flange) coated with glue and drying.
Get new valves stick ready to place, to make the valve holes precisely consistent with inner tubes and rubber edge you want to embed in the inner tube of the valve seat inside the cave. Roller pressure valves and special curing curing on the valve plate.
When you replace and repair valves, to check the integrity of the flange. Such as flange damage, must be replaced with new parts. Replace the flange of the steps are as follows:
(1) by filing a good waste tube cut a thin, oval, its dimensions for large inner tube 160×90 (mm) for a small tube of the 140×80 (mm), and then a long rough, and along the external edge is cut into the slope. For in-use gasoline to clean after the surface had been filed, brushing glue twice, and then be dried after each brushing.
(2) from the coated fabric layer in sample cut from two elliptic slice, its dimensions for large inner tube 140×70 (mm) and 120×50 (mm) for small tubes for 120×100 (mm) and 100×40 (mm) and then brush the glue on both sides, and drying.
(3) on the rubber sheet placed on small, then put glue layer thin slices of fabric and placing symmetrical. Shall have the same distance between the sides and edges, and roller compaction.
(4) the glue layer thin slices of fabric edge inner tube covered with glue and thin Central hollow punch punching diameter 5mm small round holes.
(5) in the inner tube towards electing a no wound on the inside of the rim, with a metal brush or silicon carbide grinding wheels sanding. Size of the grinding parts, size 5mm size flange on each side;
(6) remove the tire ash, wipe the surface of the ground with gasoline, then brush two glues, and drying after each brushing.
(7) in the tube brush on glue and dry parts, paste prepared flanges and flange hole coincides with the hole on the tube, and then compacting it with the roller tube plate curing on.
(8) after curing wall of the inner tube in a flange Centre holes with an awl, and embedding from the inner tube valve; placed on the bridge-shaped pad, tighten the nut. Bridge pads should follow the tube installed.
Repairing the old flange sections.
Millions of tires of the originating in China valve may crack and cause a flat tire, this potential danger has caused enormous repercussions in the tyre industry.
Experts believe that now the biggest problem is there is no way to confirm those tire valves equipped with questionable. Unless you remove the tire and internal testing, you cannot determine whether the valve is defective.
June 2 in Johnstown, Ohio, tire valves importer Taylor International Corporation (TechInternationalInc., hereinafter referred to as company Taylor) voluntary recall of 6 million sets of TR413 bayonet valves product, these valves are a topology thinking company in Shanghai, China from July 2006 to November during the production.
Taylor said valve pad may be split, so that a flat tire, resulting in tire failure. Companies promised to free not only replace the recalled valves and replace the valve gasket cracks caused by damage tires.
Taylor was announced on the official recall by the company three weeks ago May 13 informed the Distributor TR413 valve there is a potential problem. However, this is a recall many unpredictable factors.
Taylor’s company did not have the TR413 valve end user information, there is no way to confirm the identity of the end user. Taylor’s company to the National Highway Traffic Safety Administration (hereinafter referred to as NHTSA) report said that if Taylor TR413 valve production company confirmed that the batch date unrealistic.
Before the recall, NHTSA has just published on topology thinking companies (Topseal) more than 30 million sets of the TR400 series bayonet valves: a preliminary assessment. This bayonet valves were for dill air control products company in Oxford, North Carolina (DillAir Controls Products L.L.C., hereinafter referred to as the dir company) production.
Dill on April 30 valve met with NHTSA officials to discuss potential problems. Deere told NHTSA,2006 during the five months of the year production of valves may pad due to poor resistance to ozone cracking.
Dir, General Manager of BrianRigney said that is not sent within this time the dir all valve company has problems. He said, the company is an independent organization test which batch problem.
He went on to say that, once the di company confirmed the problems for which batch, dir will share with NHTSA and dealer related information. Rigney said, the company plans to publishing on the Web in the shortest possible time consumer notice on the valve.
Into action
Dir and tire dealer discount tire company in Scottsdale, Arizona, (DiscountTireInc.), have together by the RobertA.Monk family to the Nineth circuit court in Florida on March 18, is listed as co-defendants in lawsuits for product liability.
Monk near Gainesville, Florida, on November 11, 2007, deaths due to vehicle rollover. Litigation charges, from discount tire company bought the car the right rear tire, dir sales TR413 valve is installed, because the valve gasket cracked, causing tire failure, which can lead to an accident.
Prosecution requests for the losses of the dir and discount tire company, fees, interest and other compensation.
Monk, lawyer of the families of RichardNewsome and FrankMelton on June 12, to request the Nineth circuit courts, recalled tire valves and compensation for the customer.

Discount tire company Vice President in charge of marketing and public relations, Rigney and JeffStine refused to express evaluation on such lawsuits.
Dir company has issued a statement through its legal counsel, the above action, said Reddy, company would be produced or sold by other manufacturers and their brands be liable for any problems arising from the product.
In the valve before installation, there is no way to know whether valve pad will crack. Stine said, we rely on information provided by the manufacturer.

(6) fill the wound.
(7) in order to remove or in-line valves and cut into the hole to supplement good.
(8) when replacing the light car inner tube rubber mouth, knife and cut the old valves that are available, and silicon carbide grinding wheel on the inner tube valve grinding rest. And then in the file and the new rubber valve seat (flange) coated with glue and dry.
Ready to place new valve put in, to make the valve holes precisely consistent with inner tubes and valve inner tube rubber edge to be embedded in the hole. Using roller rolling block valves and special curing curing on the valve plate.
