Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief valves, in particular to a butt joint structure for installing a pressure relief valve. Background Art

[0002] A pressure relief valve is a device used to control pressure, usually in liquid or gas systems. Its main function is to release pressure when the system pressure exceeds the set value to prevent the system from being overloaded or damaged. A pressure relief valve is usually composed of a valve body, a valve cover, a spring, a piston and other components, and its working principle is based on the balance of pressure and spring force. When the system pressure exceeds the set value, the pressure will overcome the spring force, causing the valve core to open, thereby releasing the pressure. Pressure relief valves are widely used in various industrial fields, such as petrochemicals, electric power, pharmaceuticals, food processing, etc., to ensure the safe and stable operation of the system. Different types of pressure relief valves include safety valves, pressure reducing valves, overflow valves, etc. The appropriate type and specification can be selected according to specific needs. During the installation of the pressure relief valve, the interface of the pressure relief valve needs to be connected to other pipelines.

[0003] Generally, internal or external threads are set at the inlet and outlet of the pressure relief valve, and then the threads on the surface of the external pipe are screwed into it to achieve the effect of threaded connection, or flanges are used in combination with bolts for docking, or welding is used for connection. However, there is a risk of leakage through the above-mentioned various docking methods, because long-term use or improper operation may cause thread wear or damage, making it impossible to completely seal the threaded connection, thereby causing leakage.
