Pressure vessel with manual pressure relief valve

Abstract

Disclosed is a pressure vessel with a manual pressure relief valve. The manual pressure relief valve is a supplement to the pressure vessel. When a rupture disk which should be opened by high-pressure gas passing through the vessel is not opened or when a safety valve fails due to the fact that over-pressure gas is introduced into the vessel, pressure relief can be achieved in time by means of the manual pressure relief valve. The pressure vessel is characterized by comprising a tank body, the manual pressure relief valve is arranged on the outer wall of the tank body, the manual pressure relief valve comprises a valve body, one end of the valve body is fixed on the tank body through a fixed base, the other end of the valve body is connected with a pressure relief nut through threads, an ejector rod is arranged in the pressure relief nut, the front end of a valve element in the valve body corresponds to an inner cavity of the tank body, a press rod is arranged at the tail end of the valve element, and the press rod corresponds to the ejector rod.

Description

technical field [0001] The invention relates to a pressure relief valve and a pressure vessel technology, in particular to a pressure vessel with a manual pressure relief valve. The manual pressure relief valve is a supplementary configuration of the pressure vessel. The high-pressure gas passing through the vessel should open the burst disc or When the container is filled with overpressure gas and the safety valve fails, the manual pressure relief valve can be used to relieve the pressure in time. Background technique [0002] A pressure vessel is a closed container that holds gas, powder or liquid and can bear a certain pressure. The pressure vessel has a wide range of uses, and it is a kind of equipment that plays an important role in various sectors of the national economy such as petrochemical industry, energy industry, scientific research and military industry. A pressure vessel generally has a cylinder body, a head, a flange, a sealing element, an opening and a nozzl...

AI Technical Summary

Problems solved by technology

The inventor believes that although the automatic pressure relief safety valve or the addition of a bursting disc provide a guarantee for safety, if it is considered that when the automatic pressure relief safety valve fails, the bursting disc should be opened but cannot be opened, then the pressure The usual safety device configuration in the container is still lacking
