Background
Explosion vents are also called pressure relief vents and are commonly used in industrial and civil plants, boiler houses, hazardous material warehouses, military warehouses, pharmaceutical companies and the like. The explosion venting window consists of an explosion venting fan combined lockset and hardware fittings, and the explosion venting pressure value is usually 20-40 PSF. When explosion or combustion occurs in the building room, the pressure of indoor gas rises sharply, and the explosion venting door opens the window through an explosion venting fitting or device and releases the pressure to control the generation of explosion or minimize the damage degree. The explosion venting bolt has the function of quantifying the explosion venting pressure value and dynamically controlling the release pressure.
The pressure relief door of the prior patent publication No. CN205173608U automatically bounces open to relieve pressure when the internal pressure of combustible gas or dust ignited and burned in a closed space rises to a certain value, so that high-temperature and high-pressure combustion products and unburnt substances generated by burning are discharged in a non-dangerous direction through a weak part on an enclosure body before the explosion pressure reaches the ultimate strength of the enclosure body, and the enclosure body is not damaged.
However, in the practical use of the patent, the triggering value of the pressure rise cannot be controlled, so that the triggering is performed when the pressure is too high, which causes inconvenience, and the patent is difficult to return after being bounced off and cannot be recycled.
An effective solution to the problems in the related art has not been proposed yet.
