Problems solved by technology

[0003] Due to the spring structure of ordinary safety valves, the take-off accuracy of the valve will be affected by changes in time and temperature. In addition, ordinary safety valves are not designed with online data detection, so data cannot be collected on the use of safety valves. They can only be used during maintenance or monitoring. Only when the inspection can find the problem
Therefore, once the safety valve is damaged during use, it will not be able to provide proper overpressure protection, which will cause the pipeline pressure to exceed the standard and damage the transmission pipeline and supporting equipment; it will definitely cause the LNG station to shut down and bring huge economic losses to the station. and safety hazards

Abstract

The invention discloses an adjustable safety valve, and belongs to the technical field of safety valves. The adjustable safety valve comprises a valve body. A closed cylinder body communicated with a bottom channel is arranged in the valve body. The bottom channel is connected with a side cylinder. A third piston and a fourth piston are arranged in the side cylinder in a sealed mode. The top end of the fourth piston is matched with an alarm. The adjustable safety valve is simple in structure, high in safety and reliability, convenient to maintain, high in capacity of adapting to climate changes, long in service life and capable of adjusting the popping pressure of the valve online along with the time variation and climate changes.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to an adjustable safety valve. Background technique [0002] With the continuous promotion and application of LNG clean energy, the existing LNG stations will use various safety valves to varying degrees. At the same time, due to the characteristics of LNG (large thermal expansion coefficient), it is extremely dangerous. It also puts forward higher requirements for safety valve performance, quality and safety. [0003] Due to the spring structure of ordinary safety valves, the take-off accuracy of the valve will be affected by changes in time and temperature. In addition, ordinary safety valves are not designed with online data detection, so data cannot be collected on the use of safety valves. They can only be used during maintenance or monitoring. The problem can only be found during inspection. Therefore, once the safety valve is damaged during use, it will not be able t...
