Description
Technical Field
The utility model belongs to the technical field of the explosion-proof ripples valve, concretely relates to explosion-proof shielding valve of pendulum formula.
Background
A suspended pendulum type explosion-proof wave valve is commonly used in a civil air defense channel. At ordinary times, the valve and the door leaf form a certain angle under the action of gravity for ventilation in the civil air defense channel; when the door is affected by shock waves such as explosion and the like, the valve is pressed on the door leaf to cover the ventilation opening on the door leaf to realize sealing under the action of instant airflow, so that the effect of explosion wave prevention is achieved. However, after the detonation wave is finished, the valve can be opened again under the action of gravity because the valve is not acted by high-pressure airflow; in this case, dust, smoke, etc. generated along with the shock wave enter the air-raid shelter from the vent, and cause air pollution.
Disclosure of Invention
The utility model aims at overcoming the defects of the prior art and providing a suspension swing type explosion-proof shielding valve which comprises a shielding door, wherein a plurality of valves are arranged on the outer side of the shielding door, the valves are arranged on a door frame, the valves are connected with the door frame through fixing rods, the door frame is provided with a vent, the vent corresponds to the valves, a limiting groove is arranged below the vent, a limiting block is arranged in the limiting groove, the limiting block is connected with a supporting structure, sliding blocks are arranged on two sides of the limiting block, the sliding blocks are arranged in sliding grooves in the limiting groove, a movable lock catch and a positioning pin are arranged on the supporting structure, a pin rod is arranged below the supporting structure, the pin rod is arranged in a moving groove, a bottom pin block is arranged at the bottom of the moving groove, and a spring is sleeved on the bottom pin block and the pin rod, and a reset handle is arranged on one side of the moving groove below the supporting structure and connected with the movable handle, and the movable handle is connected with the supporting structure through a reset lacing wire.
The distance between the movable lock catch and the door frame is the same as the thickness of the valve.
The distance between the moving groove and the supporting structure is 1cm higher than the height of the movable lock catch.
The utility model has the advantages that: the utility model provides an explosion-proof shielding valve of pendulum formula of suspending of compact structure, possess following beneficial effect: (1) the utility model discloses a movable lock catch that sets up can push away the opposite side of movable lock catch with the valve through the power of shock wave when the shock wave hits the valve to with the valve locking, realized that the valve is automatic closed under the effect of shock wave.
(2) The utility model discloses a locating pin that is equipped with, it is big to need the air volume, and blocks the valve through the locating pin in the time need not taking precautions against the shock wave, has improved the air volume, and has avoided the mistake to touch the valve that leads to and close.
(3) The utility model discloses a handle that resets that sets up, the switch valve of being convenient for has improved the use impression.
