A kind of rainproof shock wave resistance valve
Technical field
The present invention relates to a kind of constructure ventilation special device, particularly relate to a kind of rainproof shock wave resistance valve.
Background technique
When carrying out safe design for some building, consideration is needed to avoid raindrop erosion and blast injury equipment.In order to avoid rainwater enters equipment such as building interior or airduct corrosion airduct, and prevent blast generation shock wave from causing damage to the equipment in building or personnel, need the installation of the hole inside and outside connecting building thing to have the shock wave resistance valve of rainproof function.When rainy, stormproof louvre can stop rainwater; When blasting, shock wave resistance valve can cut out instantaneously, cuts off connecting passage inside and outside building, avoids personnel and equipment in building to sustain damage.This shock wave resistance valve uses on rainwater frequently maybe may blast the building to attack etc., is specially one and has and prevent rainwater to enter in building or can keep out personnel and equipment in foreign impacts ripple infringement building in airduct.
The valve of prior art has certain defect, and 1, there is the valve of rainproof function, not there is shock wave resistance ability.2, there is shock wave resistance ability valve, not there is rainproof function.3, not there is the function that anti-Tornado Impact thing clashes into.
Summary of the invention
The object of the invention is: for the problems referred to above of the prior art, provide a kind of rainproof shock wave resistance valve, when not blasting, collecting annulus and valve disc form a whole stormproof louvre, can stop that rainwater enters in building or airduct.When blasting, closing valve disc by axle, connecting rod and spring Close All under shock wave, shock wave is stopped outside the building.When there is tornado, grid can keep out the shock of the alluvium that tornado is rolled.
Technological scheme of the present invention is:
A kind of rainproof shock wave resistance valve, comprise framework, grid, closedown valve disc, collecting annulus, water chute and water guide board, described framework comprises water chute, described water chute is embedded in two body side frames, described grid is welded on described framework and described collecting annulus, described collecting annulus and described closedown valve disc composition stormproof louvre, rainwater can flow into described collecting annulus along described stormproof louvre, in described collecting annulus rainwater again in framework water chute flow into bottom rainproof shock wave valve, finally discharge rainproof shock wave valve by described water guide board.
Further, described rainproof shock wave resistance valve also comprises axle, bearing, connecting rod, spring, together with described closedown valve disc welds with described axle, one end of described axle is connected with spring with described bearing, connecting rod, and all closedown valve discs are closed by described bearing, connecting rod and spring simultaneously and opened.

Further, when normally ventilating, described closedown valve disc is in open mode, is connected to form stormproof louvre, realizes rainproof function with described collecting annulus; When explosion happens, shock wave is in described closedown valve disc, and described closedown valve disc turns to along described axle and closes completely, is blocked in by shock wave outside building; When shock wave disappears, described closedown valve disc, due to spring action, automatically reverts to full open position.
Further, described collecting annulus all adopts galvanized steel or stainless steel, and described collecting annulus two ends are welded on framework, and described collecting annulus two ends communicate with described water chute, and in described collecting annulus, rainwater can flow in described water chute.
Further, described closedown valve disc all adopts galvanized steel or stainless steel, and described closedown valve disc is by upper and lower two sheet material forming machine wings, and one end rivet interlacement of described closedown valve disc, the other end of described closedown valve disc is welded on axle.
Further, described grid all adopts galvanized steel or stainless steel, and described grid is welded by horizontal horizontal stripe and vertical bar criss-crossing, and the surrounding of described grid and framework and grid are weldingly connected.
Further, described rainproof shock wave resistance valve also comprises manger board, and described manger board is that dash is to avoid entering airduct bottom valve, and water is all discharged to bottom described rainproof shock wave resistance valve.
Advantage of the present invention is:
1, the beneficial effect achieved by the present invention is: realize a kind of valve and possess two kinds of functions simultaneously, can rainproof also can withstand impacts ripple, can prevent rainwater from entering building internal corrosion equipment or airduct, shock wave also can be stoped to enter damage personnel and equipment in building.
2, when there is tornado, grid can keep out the shock of the alluvium that tornado is rolled.
