FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used for process equipment explosion protection. Blast valve comprises a valve body, heat insulating and rupture elements, lined load trim. Valve body is made in the form of a lower cylindrical, middle conical and upper cylindrical parts. In the lower cylindrical part there is a lined load trim. In the upper cylindrical part of the valve body there arranged is a heat-insulating element and a sealing membrane.
