[0002] In the natural gas transmission system, stable control of the pressure in the pipeline is the key to ensuring the safe operation of the system. Traditional natural gas pipeline pressure relief devices often have problems such as slow pressure relief response, inaccurate pressure monitoring, and untimely safety warnings. It is difficult to quickly and effectively reduce the pressure in the pipeline in an emergency, thereby increasing the risk of equipment damage and safety accidents. Therefore, it is necessary to develop a new type of natural gas pipeline pressure relief device with a reasonable structure, easy operation, safety and efficiency to meet the safety needs of modern natural gas transmission systems.

By arranging a pressure relief component, when the pressure inside the natural gas pipeline body is too high, the natural gas inside the natural gas pipeline body enters the inner cavity of the piston cylinder through the gas storage shell, and the natural gas pushes the piston plate through the pressure, and the piston plate slides upward due to the elasticity of the pressure spring, so that the natural gas enters the inner cavity of the gas storage tank through the connection between the pressure relief pipe and the gas storage tank, so that the natural gas can be relieved when the pressure inside the natural gas pipeline body is high, thereby avoiding safety accidents.
