Description

CNG gun head inflation valve capable of being automatically opened and closed Technical Field The utility model relates to the technical field of CNG (compressed natural gas) inflation equipment, in particular to an automatic opening and closing CNG gun head inflation valve. Background In the CNG (compressed natural gas) filling process, the traditional inflation valve has the problems of complex operation, unstable sealing performance and the like. For example, some inflation valves require operators to perform more complicated operation steps when being opened and closed, which not only consumes time, but also is easy to leak gas due to improper operation, and meanwhile, after long-term use, the sealing parts of the valves are easy to wear, so that the sealing effect is reduced, and the safety and efficiency of air filling are affected. Therefore, the development of the CNG gun head inflation valve which is simple and convenient to operate, good in sealing performance and capable of being automatically opened and closed has important practical significance. The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of utility model The utility model aims to solve the defects of the traditional CNG inflation valve in the background art, and provides an automatic opening and closing CNG gun head inflation valve so as to realize simple and convenient operation, improve the sealing performance and the air filling efficiency and ensure the safety of the air filling process.
