Abstract

The invention discloses a novel air-inflation-preventing gas valve. The novel air-inflation-preventing gas valve comprises a valve body and a valve element, wherein the valve body is provided with an inflation inlet, the valve element is matched with the valve body, and the two ends of the valve element are open; a poking preventing component arranged in the valve element is provided with a first guide hole communicated with the inflation inlet; a second guide hole communicated with the first guide hole is formed in the valve element, and a sealing part making the second guide hole be sealed or through is arranged in the second guide hole. According to the novel air-inflation-preventing gas valve, the poking preventing component is adopted, the first guide hole is formed in the poking preventing component and located above the sealing part, it is prevented that the first guide hole is damaged by the sealing part to deform, the sealing part is separated from the inside the second guide hole, and the sealing function of the sealing part is lost, and the sealing function of the sealing part is guaranteed. Therefore, the phenomenon of air inflation of a liquefied gas steel cylinder can be prevented under the condition that a liquefied gas inflation gun matched with a liquefied gas steel cylinder gate valve is not used.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a novel anti-filling gas valve. Background technique [0002] In recent years, with the rapid development of economy and society, liquefied petroleum gas, as a commonly used fuel, has been widely used in various fields of national economy and people's lives. Its manufacturing quality is of great significance to ensure the safe use of liquefied petroleum gas cylinders. The manufacturing industry of liquefied petroleum gas cylinders and their accessories shoulders an important mission to ensure the manufacturing quality of liquefied petroleum gas cylinders and ensure their safety performance. However, due to factors such as illegal filling of liquefied petroleum gas and illegal operation, unsafe accidents of liquefied petroleum gas have occurred from time to time, which have seriously affected the safety of people's lives and property. [0003] The gas valve of the currently used l...
