Pressure relief valve with rapid cover opening function

Abstract

The invention discloses a pressure relief valve with a rapid cover opening function, and belongs to the technical field of automatic pressure relief equipment. The pressure relief valve with the rapidcover opening function comprises a valve base, a valve cover, electromagnets, a pressure sensor and a PLC; one end of the valve cover realizes opening and closing connection with the valve base through an opening and closing mechanism; a pair of lock catches is arranged at the other end, corresponding to the opening and closing mechanism, of the valve cover; the lock catches are provided with iron cores in the middles of the front ends of the lock catches; the electromagnets are arranged on the valve base and correspond to the iron cores; the PLC controls the electromagnets to be powered on or off according to pressure data detected by a pressure sensor; the electromagnets attract the iron cores when being powered on, so that the valve cover is tightly fastened to the valve base; and theelectromagnets lose magnetism when being powered off, and at this time the valve cover is opened by pressure in a pressure relief channel. The pressure relief valve has the advantages that air leakageand pressure relief can be realized by quickly opening the cover, so that explosion caused by too high air pressure in a cabin is avoided and the safety is improved; and the pressure relief valve canbe reused after the completion of pressure relief work, so that the waste of resources and articles is reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of automatic pressure relief equipment, and in particular relates to a quick cover opening pressure relief valve. Background technique [0002] The quick opening cover pressure relief valve is used to quickly open the cover to release the air pressure when the air pressure of the equipment is too high, so as to protect the equipment and prevent personnel from being injured. The general pressure relief opening device needs to consider many factors such as production requirements, equipment pressure, explosion relief frequency, corrosion or aging degree, service life, ambient temperature and installation location. For places without special environmental requirements such as heat preservation and moisture retention, the quick opening pressure relief valve is the most efficient and economical, and it can also be used repeatedly. [0003] There are several kinds of old pressure relief equipment in the past: the...

AI Technical Summary

Problems solved by technology

This method is basically not used now, because the damage of the cover will lead to a large waste of resources, and there is a great safety hazard. If the pressure reaches a certain level and the cover cannot be opened in time, it will cause an explosion.

The second is to use the pressure of gas or liquid to control the opening and release of pressure. However, over time, the gas or liquid used will corrode some parts of the opening mechanism and cause equipment damage.
