Bidirectional shock wave resistant valve

Abstract

The invention provides a bidirectional shock wave resistant valve. The bidirectional shock wave resistant valve comprises a valve body and rotating shafts mounted in an inner cavity of the valve body,wherein valve blades are mounted on the rotating shafts and can rotate along with the rotating shafts; one ends of the rotating shafts penetrate through sleeve through holes, and the other ends of the rotating shafts are connected with the side wall of the valve body; sleeves are connected with connecting rods through connecting pieces; the connecting pieces are connected with one ends of springs; the other ends of the springs are connected with one ends of hooks; the other ends of the hooks are connected with fixing blocks; the fixing blocks are arranged on the outer surface of the side wallof the valve body; the two rows of valve blades are arranged; valve blade baffles are mounted in the inner cavity of the valve body; and sealing frames and sealing strips are further arranged in theinner cavity of the valve body. The bidirectional shock wave resistant valve solves the problem that a bidirectional shock wave resistant valve is lacked in the prior art, promotes improvement of social productivity, promotes economic development, consolidates production safety and guarantees life safety of people.

Description

technical field [0001] The invention relates to the field of shock wave valves, in particular to a two-way anti-shock wave valve. Background technique [0002] At present, petrochemical, nuclear power and other industries must consider the HVAC system when designing control rooms. The national standard stipulates that anti-shock wave valves must be installed at the air inlet and outlet to resist external shock waves and protect the safety of indoor personnel and equipment. When the shock wave comes, the shock wave valve will be closed instantly to block the shock wave outside. When the shock wave disappears, the shock wave valve will automatically reset under the action of the spring to allow normal ventilation. [0003] Nowadays, the anti-shock wave valves with large ventilation volume on the market are all unidirectional and can only withstand the shock wave from one side; while the valves that can withstand the shock wave in both directions have a smaller ventilation volu...
