VEHICLE-PROCESS EXPLOSION-PROOF CONTAINER Russian patent published in 2018 - IPC F42D5/45 F16K17/36 E04B1/92 

FIELD: explosives.

SUBSTANCE: invention relates to the field of storage and transportation of explosives. Proposed explosion-proof container includes vessel in form of metal tank with filling and emptying assemblies. Explosion-proof valve is provided, which includes a body, heat-insulating and rupture elements, and a lined load gate, movably connected to the valve body. Valve body is made in the form of lower cylindrical, middle conical and upper cylindrical parts. In lower cylindrical part there arranged is a lined load gate valve covering a hole made in the body of the protected object. In upper cylindrical part of the valve body there arranged is a heat-insulating element and a sealing membrane pressed to the valve body by means of a cover plate hinged to a lever interacting with a baffle plate. An attachment assembly of the blast element is fixed with its upper part on the lever and with its lower part on upper cylindrical part of the valve body. Rupture element mounting assembly consists of wire, locking bolt, fork, valve cover lever, nuts, two drums, located respectively in fork of valve cover plate lever and in upper cylindrical part of valve body. Lined load gate movable connection with valve body base is made in form of three rods vertically installed in the holes made in the peripheral part of the body of the lined load gate. By lower part, rods are fixed in valve body base, and in the upper part they have a damping device fixed to the horizontal crosspieces of the rods, and facing the load gate; each of the three damping devices is fixed to a horizontal crosspiece rigidly connected to the rod and made in the form of a circular disk on which the base of the damping device, made of rigid shock-absorbing material of the "Agat" type, which is connected with a sleeve made of elastomer, which has a central hole through which the rod passes. Sleeve has at least three holes aligned with rod, in which there are elastic elements, cylindrical helical springs, top end thereof by means of fastening elements is connected with base of damping device, and bottom is in non-compressed state and protrudes beyond sleeve bottom plane at distance defined by force generated with impact blast wave. To sleeve end surface, on the side of the free end of elastic elements arranged in its holes aligned with the rod, a safety element is rigidly attached, made in the form of a conical surface, the lower base of the cone being supported by the sleeve, and the top part is formed with an opening into which the rod is enters.

EFFECT: invention allows improving explosion safety of container.
