To check whether the tire valve core leak
To check whether the tire valve core leak, you can apply soap water on the valve core to check, if the leak will hear a“Sizzling” sound, or see a continuous small bubble. Check the valve port before inflating. If the valve valve and valve core with a bad, uneven, not easy to inflate. If the valve nozzle and valve core fit well, the valve should be cleaned, while the valve valve and valve core fixed, do not loose. To the right amount of inflation, tire pressure can not be too high, high tire pressure will make tire cord too much stretch, resulting in reduced strength, affect the life of the tire. The filled air must not contain moisture or other impurities to prevent deterioration or damage to the tire rubber. When the car has just stopped, do not inflate, because at this time the temperature of the gas in the tire is high, tire pressure, to wait for the tire to cool before inflating.
tire valve and valve core
If the valve core is used for too long, it will become stale and stick to the inner wall of the valve nozzle, resulting in the separation of the valve seat and the core body, and it is difficult to remove the residual part of the valve nozzle. If the valve nozzle slightly deformation or internal thread damage, the valve core screwed to the valve mouth can not be removed, at this point the valve core screwed to the end, and then the valve core wrench with a tap on the internal thread can be removed; If it is not wrung out, will be able to clean up the part of the clean out, and then with a silk attack into the 5 -6 teeth, the valve core valve out, and then install a new valve core. If the valve core thread rust dead, can drop a few drops of gasoline to the valve hole or immersed in gasoline, after a moment and then drop a few drops of oil can be removed. If the inner tube valve screw is deflated, the screw under the compression nut is damaged, the seat is bent, or the valve nozzle tube is damaged and not sealed, it must be replaced.
Repair tire valve
Damaged inner tube valve, such as thread fastener, can be repaired by Tap and die. Replacement valve mouth should be taken out from the inner tube through the gap, if there is no gap turn the inner tube wall, can cut 7-8 mm outlet; Install the bridge pad and tighten the valve head nut with a wrench. The valve nozzle bridgehead shall be installed with its round long axis aligned in the circumference of the inner tube rather than horizontally, and the bridgehead shall not be bent, and its end shall be set at 30 ° . The bridgehead should be mounted facing out, with the bent end of the valve facing across the tube to fill the wound; the hole cut to remove or insert the valve end should be well patched. When replacing the rubber nozzle on the inner tube of a portable vehicle, the old valve nozzle can be cut with a knife and the remaining part of the valve nozzle can be rubbed on the inner tube with a silicon carbide grinding wheel, then apply glue to the bruised area and the new rubber valve seat (flange) and dry. Place the new valve seat in place so that the valve seat exactly matches the tube seat and the rubber edge of the valve seat is embedded in the tube seat; roll the valve seat, and the vulcanization is carried out on the flat plate used for the specialized vulcanization valve.
