Six technical requirements of automobile valve
The main function of automobile valve is to charge and bleed the tire and to maintain the sealing after the tire is inflated. Although the valve is only a small part compared with the large mine car, its importance is self-evident, and the production of valve must also have corresponding technology. The following is a brief introduction to the six technical requirements of mine automobile valve.
First, the main material of mine automobile valve is based on brass in China. The best main material is lead brass, because it can improve the quality of valve and bring some economic benefits.
Second, assembly performance requires that all parts of the valve nozzle should not have air holes and shrinkage holes. Cracks and mechanical damage will affect the valve performance defects, and the metal surface of the valve needs anticorrosive coating.
Third, the bending requirements, the main body of the valve can be used manual mechanical tools bending parts, in order to ensure that the angle of the bending must be small, should not produce cracks and fracture and other defects.
Fourth, the core cavity of the valve should be kept clean and no debris or other debris is allowed.
Fifth, sealing performance, one of the most important performance. Therefore, the inspection of sealing is very important. In production, the sealing performance must be tested according to random sampling in batch to check whether there is any bubble escaping from each part.
Sixth, the product packaging and the valve mouth packing box of mining vehicles must have the product name, model, quantity, manufacturer name, delivery date and trademark before it can be put into the market.
The production of mine automobile valve is not a simple mass production, which contains a large amount of technical content. The quality of each valve is related to the safety of mine automobile gas transportation. The above six mine car valve requirements hope to improve your understanding of the valve, welcome to continue to visit our website.
