Technical Field

[0001] The utility model relates to the technical field of gas lock valves, in particular to a leak-proof and high-pressure resistant gas delivery valve. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by urban residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial coal gas, liquefied petroleum gas and biogas. According to the source of gas, gas can usually be divided into natural gas, artificial coal gas, liquefied petroleum gas and biomass gas. Compared with developed countries, my country's gas supply industry started later. The gas currently distributed mainly includes coal gas, liquefied petroleum gas and natural gas.

[0003] When the existing gas lock valve is installed, it is generally lack of direct fixation of the control dial of the gas valve, so that the gas valve cannot be kept in a completely locked state. When it is accidentally misoperated, it is very likely to cause the gas valve to be opened, causing the risk of gas leakage, thus bringing safety hazards; at the same time, when the gas is transported, it will be transported through the gas pipeline, and a large number of valves will be used to control the flow of gas, but the sealing parts of the valve are easy to wear during operation. Once the wear exceeds the limit, it will cause internal leakage and failure of the valve, and even cause serious production accidents; therefore, a leak-proof and high-pressure gas transmission valve is proposed.
