[0002] Natural gas is a clean energy source. With the continuous advancement of technology, my country's natural gas supply has continued to rise. Pressure regulators are one of the indispensable instruments in the utilization of natural gas. The use of pressure regulators is conducive to the rational use of gas. Natural gas pressure regulators are a device that can maintain stable downstream pressure regardless of how the gas flow and upstream pressure change. Natural gas pressure regulators should be able to: reduce the upstream pressure to a stable downstream pressure; when the pressure regulator fails, it should be able to limit the downstream pressure within a safe range. The biggest function of a natural gas pressure regulator is to maintain a stable pressure when the gas is in use, thereby ensuring that gas appliances have a stable fuel-air ratio (the ratio of gas to air); pressure regulators are used in the gas supply system to reduce and stabilize the gas pressure at an appropriate level that enables the gas to be used safely, economically and efficiently. Natural gas pressure regulators are mainly used in gas pipelines, such as air, nitrogen, oxygen, ammonia, liquefied gas, natural gas and other gases.

[0003] However, many existing natural gas pressure regulators are generally installed and connected by bolts, which not only has low installation stability but is also prone to leakage.
