Description

Technical Field

[0001] The present invention belongs to the field of pipeline pressure systems, and in particular relates to a pressure tank body with a rapid pressure relief structure and a pressure relief system. Background Art

[0002] The pressure relief manhole is a safety emergency ventilation device installed on equipment and storage tanks in petrochemical industry. It is usually used in conjunction with the breathing valve installed on the top of the tank to maintain the normal pressure in the tank. It can avoid accidents caused by sudden overpressure or vacuum in the tank due to unexpected reasons, which may damage the storage tank. It has the advantages of constant pressure discharge, constant pressure suction, flexible closure, compact structure, good sealing performance, safety and reliability.

[0003] Although the existing pressure relief manhole can simply meet the use requirements after assembly. However, in the actual use process, the pressure relief manhole basically remains sealed. If the pressure inside the pressure relief manhole needs to be adjusted, the pressure relief manhole needs to be opened to release the pressure in the tank body, but the pressure in the tank body cannot be accurately adjusted. If the working state of the tank body is in an abnormal pressure state (overpressure or negative pressure), directly opening the tank body will affect the normal work in the tank body. Therefore, we have introduced a pressure tank body and pressure relief system with a rapid pressure relief structure to solve the above problems. Summary of the invention
