FIELD: machine building.
SUBSTANCE: explosion-proof device with a bursting disk includes a valve body, a gate, and a bursting element. A unit for the bursting disk fastening is installed in the upper cylindrical part of the valve body. The bursting disk is clamped between rings. The rings are connected to each other by two diametrically opposite plates and screws. One of the holes for the screws in the plate is of an oblong shape. In the lower cylindrical part of the valve body there arranged is a lined load gate covering a hole made in the body of the protected object. The said gate is connected in a movable manner to the valve body by means of at least three flexible links. The flexible links are made as elastic belts, one end of the belts is hinged to the valve body, and the other one is hinged to the load gate. Elastic belts are layered and have the alternation of elastic and damping layers. A vibration damping paste, for example of the VD-17 type, is used as the damping layers, and an elastomer is used as the elastic layers.
EFFECT: improving the efficiency and reliability of protection of process equipment against explosions in case of emergencies by increasing quick action and reliability of bursting elements actuation.
