Abstract

The invention provides an anti-explosion valve. The anti-explosion valve comprises a valve body, a valve blade and two sets of springs placed in a valve cavity, wherein the valve cavity is formed in the valve body, two valve openings located in the two opposite side surfaces of the valve cavity are formed in the valve body, and the two long-side walls, connected with the two valve openings, of thevalve cavity are outward-protruded arc walls; the valve blade is arranged slidably, and the two side outer surfaces, opposite to the two long side walls of the valve cavity, of the valve blade are ina arc shape; and the two sets of springs are located between the valve blade and the two valve openings and positions the valve blade in the middle of the valve cavity so as to make the two valve openings communicate. According to the anti-explosion valve, two-way explosion preventing and two-way resetting can be achieved, during impacted, the impact force acts on the valve blade to compress oneof the two sets of springs and moves to the corresponding valve opening so that the valve blade seals the corresponding valve opening, and when the impact force is disappeared, the valve blade resetsto the middle of the valve cavity under the function of the springs so that the two valve openings communicate with each other.

Description

technical field [0001] The invention relates to a valve body structure, in particular to an anti-explosion valve. Background technique [0002] The anti-knock valve is usually installed on the outer wall of the protected building. Under normal circumstances, the anti-knock valve is equivalent to the ventilation inlet or outlet. When the destructive blast shock wave arrives, the anti-knock valve will automatically adjust or close according to the overpressure. Blocks damage to building interiors from explosion shock waves. [0003] Existing antiknock valve, such as Chinese patent application number is: 200920148353.0 discloses a kind of antiknock valve, is provided with air outlet on the surface of unit valve body, is provided with base plate in unit valve body, is provided with slide block on the base plate, slide The blocks are elastically connected to the base plate. The antiknock valve with this structure is simple in structure and has a single function, and can only pl...
