Pressure vessel safety valve

Abstract

The invention relates to the technical field of safety valves, and discloses a pressure vessel safety valve. The valve comprises a valve body, a valve cover, a valve bottom, a valve bonnet, a valve rod and a connector. The valve cover is detachably and fixedly arranged at the upper end of the valve body, the valve bottom is detachably and fixedly arranged at the lower end of the valve body, the valve cover, the valve body and the valve bottom are sequentially connected to form a cavity structure, a discharging port is formed at one side of the valve bottom, and a feeding port is formed at the lower end of the valve bottom; and the valve bonnet is located in the valve cover and the valve body, the valve rod is located in the valve body, and the connector is located in the valve body and the valve bottom. The valve bonnet is fixedly arranged at the upper end of the valve rod and connected with the inner wall of the valve cover, and the connector is fixedly arranged at the lower end of the valve rod. The safety valve is good in sealing performance, can effectively solve the problems that an existing safety valve is poor in sealing performance and easy to cause overflow leakage of gas or liquid, is convenient to disassemble and assemble, and solves the problem that the existing safety valve has limitation in use.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a pressure vessel safety valve. Background technique [0002] The safety valve is a kind of opening and closing part, which is in a normally closed state without external force. When the medium pressure in the equipment or pipeline rises above the specified value, it prevents the medium pressure in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system. special valves. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. [0003] The existing safety valves for pressure vessels are not well sealed, which can easily lead to gas or liquid leakage, affecting the accuracy of internal pressure, and when the gas or liquid passes through the sa...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a safety valve for pressure vessels. The safety valve has good sealing performance, which can effectively solve the problem that the existing safety valve has poor sealing performance and easily causes gas or liquid leakage. At the same time, the safety valve can effectively It solves the problem that it is inconvenient to remove impurities in the gas or liquid when the gas or liquid passes through the safety valve, and the safety valve is easy to disassemble and assemble, which solves the problem that the existing safety valve has limitations in use
