The invention provides a novel explosion door structure, the novel explosion door provided with a
universal joint can automatically reset after the door cover is detonated under certain pressure, the door rod and the door cover cannot deform after continuous
detonation, and the door rod and the door cover can be continuously pressed on the original sealing
gasket, so that a better sealing effect is achieved. The sealing
gasket adopts a structure that the lower part of the cross section is U-shaped and the upper part is triangular, a sealing structure is adopted among the valve body, the sealing
gasket and the door cover, the sealing gasket is placed on a U-shaped groove of the valve body, the door cover is pressed into the sealing gasket, the door cover adopts a triangular structure, and the valve body, the sealing gasket and the door cover are tightly pressed and connected, so that the contact surface is larger, the sealing effect is better, and larger pressure can be borne; the sealing gasket is made of a
graphite packing material, is low in cost, has a better sealing effect at a high temperature for a long time and is simple to replace. The novel explosion-proof door adopts a
chromium plating process, and is better in
corrosion resistance and
wear resistance. By means of the technical scheme, the technical problems that in the prior art, when an explosion door returns, resetting is not accurate, and sealing is not tight are solved.
