Problems solved by technology

[0003] During the use of natural gas pressure regulators, natural gas leakage of natural gas pressure regulators may occur. Leakage of natural gas pressure regulators occurs every year. Part of the reason is that natural gas pressure regulators are poorly sealed, resulting in natural gas leakage accidents. Therefore, it is proposed A natural gas pressure regulator with high anti-leakage safety solves the above-mentioned problems

Abstract

The invention discloses a natural gas pressure regulator with high leak-proof safety, which comprises an outer casing, a pipe body and flanges arranged at both ends of the pipe body, and the flanges are used for connecting with gas pipelines so that The device is connected in series with the gas pipeline, the outer casing is fixed on the outside of the pipe body, and a through hole communicating with the inside of the outer casing is opened on the pipe body, and the inner middle part of the outer casing is a cylindrical cavity, and movable parts are set in the cavity. A sealing assembly is installed on one side of the movable plate close to the through hole, the sealing assembly is used to block the passage of gas in the gas pipeline, and an adjustment assembly is installed on the other side of the movable plate, which is used to adjust the position of the movable plate. In order to achieve the function of regulating the gas delivery pressure, the sealing component contains an auxiliary sealing block arranged in the cavity. The invention has simple structure, good leakage prevention effect, convenient adjustment and high safety in use.

Description

technical field [0001] The invention relates to the field of natural gas, in particular to a pressure regulator for natural gas with high anti-leakage safety. Background technique [0002] At present, the ideal gas supply system does not need a pressure regulator to transport gas from the wellhead to the end user. The conditions for maintaining such an ideal supply system are that the user demand is constant, the supply capacity of the mine is constant, and the two are consistent. Such a system is actually impossible to exist. The biggest function of the natural gas pressure regulator is to keep the gas at a stable pressure during use, so as to ensure that the gas appliance gets a stable fuel-to-air ratio. The gas supply system uses a pressure regulator to reduce the gas pressure. And stabilized at an appropriate level that enables the gas to be used safely, economically and efficiently. [0003] During the use of natural gas pressure regulators, natural gas leakage of natu...
