Name is explosion-proof, explosion-proof nature can be. Its basic principle is to add an overpressure valve exhaust valve at the mouth of the ordinary body, its role is: When the tire pressure exceeds a set limit, discouraged bore out the exhaust valve automatically when the exhaust resulted in a slight decrease in tire pressure when the vent valve will automatically shut down, the pressure is still maintained within a predetermined range. After installing this product, tires do not have to consider the so-called standard pneumatic pressure every time, but has been inflated to the pressure of the exhaust valve is reached.

Rubber-metal valve is made of metal (brass) tubes and rubber cone formed, this rubber cone with the base to form a whole, base metal valve can replace the necessary valve pad. The inner and outer metal sleeve has a threaded, so you can use the standard valve core and cap. In order to combine with the rubber during vulcanization well, the base made of metal pipe with an annular groove. Rubber-metal valve over the whole metal valve has many advantages, so the rubber valve has been widely used. The main advantages are as follows: A rubber valve is used to pad the bottom valve fixed on the inner tube curing method, so it has a great combination of flexibility and tightness. 2 conical valve tube can be placed upright in the rim, and no valve hole near done. When the car is driving, such as tube is damaged (if there is not perforated), valve will slowly penetrate into the interior of the tire, tubeless tires will not damage the wall. Nuts fixed on the rim of the metal valve, in case of the above, it will make the tube rupture. 3 rubber-metal valve is much lighter than the metal valve, such as the weight of the rubber metal valve 20 to 25 grams, the weight of the corresponding metal with this valve, and 50 to 55 grams of the metal used to make weight valve fixed on the tube valve pad is also up 15 to 16 grams. Therefore, the use of rubber-metal valve can narrow tube unbalance. 4 Use the rubber-metal valve, can reduce a lot of non-ferrous metals consumption. 5 When using a rubber valve or plastic valve base package can be attached to the tube without the use of a valve reinforcement mat.

Tire valve is indispensable hollow part of a very important. Currently, the most commonly used valve is a spring with several types of valve cores. Modern hollow tube valve is a check valve for filling air, and holding the tube; may emit air in the tube through the check valve when necessary. The basic requirements valve structure is to ensure that: (1) easy to inflate and deflate; (2) can check the internal pressure in the tube; (3) air tightness (valve does not leak air); (4) can be combined with a solid tube wall, but can be replaced; (5) valve structure types and a variety of simple and uniform specifications of the components are to be replaced; (6) a solid tube working pressure; (7) light.

① check valve flange and adjacent portions of the tube or without defects. As technology in good condition and well-fixed valve, check valve. ② If repairable valve tube, threaded damage only available wire tapping and threading wire board repair. ③ even if the valve is too damaged, you should replace it. ④ from the tube through the cracks inside the valve removed. When the tube wall without cracks, you can cut the export 7-8mm. ⑤ inside the tube into the new valve, embed flange hole, mounted on the bridge-shaped pad, and tighten with a wrench valve nut. Valve bridge pad should be installed, which are arranged circumferentially along the long axis of its elliptical tube, rather than horizontal; allowed to bend and bridge-shaped pad, which ends should be 30 degrees. To bridge toward the outside when the pad is mounted, the curved portion of the valve tube should be sideways toward the direction of the tube. ⑥ fill the wound and repair intact. ⑦ To remove or embed the valve hole and cut into subsidies intact. ⑧ When replacing the light on the car's rubber mouth tube used a knife cuts off the old valve and valve with silicon carbide wheel rubbed off on the remaining portion of the tube. Then fell over the place and the new rubber valve seat glue water, and dried. ⑨ posted on the new valve ready place, to make the valve hole precisely consistent with the tube holes and rubber edge valve seat tube to be embedded inside the cave. Rolling with a roller valve seat, and in a special vulcanization vulcanization valve with flat.
