After a long distance, the mine car needs to pump air for the tire, so how to check the gas valve in the mine? Inflation should wait until the tire has cooled off. Because driving tire friction with the ground will make tires in the process of temperature rising, the air in the tire heat expansion, lower density, pressure drop, at this time of the valve is not into the gas in the mouth.
When preparing to pump air for the tyre, it is necessary to check the integrity of the valve first, and check whether there is any deformation. If you find that you need to replace the valve immediately to prevent other problems from happening. When filling, pay attention to cleanliness. The injected gas cannot be mixed with excessive water and oil droplets. Once the water and oil droplets enter the inner tire, it will cause deterioration to the inner tire rubber. Second, inflating is to control at best, too much too little can affect the service life of valve mouth. When cleaning the valve mouth, be careful not to send the valve core. After inflation, check whether there is air leakage in the valve. After confirming the air leakage phenomenon, tighten the valve cap to prevent the foreign body from entering the valve mouth and cause the valve failure. Conversely, if there is a leak, the valve should be replaced immediately.
Although it is common to inflate a tyre, the valve is only a small device, but sometimes the small part determines a lot of important things.
The above is the content of the check valve mouth when the tyre is inflated. I hope it will be helpful to you. Tengda valve mouth production of various types of valve mouth, is shandong province largest mining automobile valve mouth manufacturer, has the need to contact us.
