Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief pipes, and particularly relates to a pressure relief pipe fitting. Background Art

[0002] Pressure relief means discharging gas or liquid under a certain pressure from the system through setting a pressure relief device or opening a discharge port in the system to reduce the pressure in the system. Pressure relief is a way to reduce the energy of the system. Therefore, the gas or liquid in the system still exists after pressure relief, but only the pressure is reduced.

[0003] According to the patent document: CN213177005U, there is disclosed an instrument pipe fitting with a pressure relief function, including a pipe body and a pressure relief port arranged at the bottom end of the pipe body. A connecting block is slidably arranged inside the pipe body. A sealing plug for sealing the pressure relief port is fixed at the bottom end of the connecting block. A threaded rod is rotatably arranged at the top end of the connecting block. A screw sleeve is fixed at the top end of the pipe body. The threaded rod passes through the screw sleeve and is connected and fixed with a support plate at the top end. The threaded rod is matched with the screw sleeve. A sleeve box is fixed at the top end of the support plate. A smooth round rod is slidably arranged inside the sleeve box. Through the interaction between the first clamping block and the second clamping block, the grip can be firmly installed on the upper part. Rotating the grip can control the lifting of the sealing plug, so as to control the opening and closing of the pressure relief port. The structure is simple and convenient to use. The control traction device can make the grip be disassembled, effectively preventing the adverse consequences caused by the misoperation of idle personnel.

[0004] At present, the traditional pressure relief pipe fittings do not have a warning function during daily use. Excessive pressure inside the pipeline will cause continuous pressure relief, which cannot be fundamentally solved. If continuous pumping causes continuous excessive pressure, it will cause pipeline damage. Moreover, it is time-consuming and laborious to disassemble, and a wrench is needed, which cannot meet the use requirements. Summary of the Utility Model
