Embodiment

[0051] Embodiment: a frame-integrated impact-resistant airtight tornado valve, including a frame 10 and a valve leaf 2 .

[0052] Such as Figure 4 As shown, the valve blade 2 is in the shape of a plate, and three sides thereof are bent toward the windward surface 22 and extended to form a U-shaped bent portion 21 . The bent portion 21 includes a side bend 23 and a front bend 25 . Wherein, the bent side 25 is located on the side opposite to the unbent side 28 of the valve leaf 2 . The side bends 23 are located on both sides of the front bend 25 . The front edge bend 25 is provided with a hole B26 for fixing the extension spring 5 and a water outlet 27 for draining water and ash. The side bend 23 is provided with a hole A24 for the rotation mechanism 3 to pass through.

[0053] The frame 10 includes a quadrangular frame body 11 enclosed and fixed by four cover plates, reinforcing ribs 15 and a bottom plate 13 . Reinforcing ribs 15 are fixed inside the frame body 11 to divi...

Abstract

The invention relates to building heating and ventilation equipment of new wind inlets and wind exhausting outlets, and particularly to a frame integrated type shock resistance airtight tornado valve capable of resisting high-grade shock waves and tornadoes. A frame of the frame integrated type shock resistance airtight tornado valve comprises a frame body, a plurality of strengthening ribs and base plates. The strengthening ribs are fixedly arranged in the frame body; the frame body is divided into a plurality of ventilating passageways through the strengthening ribs, and each base plate with a ventilating opening is fixedly arranged in the middle of the corresponding ventilating passageway. Valve blades are rotatably connected with the frame. One ends of pulling springs are fixed on the frame, the other ends of the pulling springs are fixed to the valve blades, and the pulling springs supply preset force to the valve blades. When the ventilating valve is in a ventilating state, the ventilating openings are in a ventilating state; and when the ventilating valve is in a closed state, the bottom faces of the valve blades make planar contact with the base plates, and the ventilating openings are closed. The requirement of ventilating of a large wind capacity can be met, when the valve is suffered the high-grade shock waves and tornadoes, bilateral shock wave resistance can be realized, and the frame integrated type shock resistance airtight tornado valve has the advantages of being quick in response, simple in structure and strong in airtightness.

Description

technical field [0001] The invention relates to HVAC equipment for fresh air inlets and exhaust air outlets of buildings, especially ventilation valves for fresh air inlets and exhaust air outlets of buildings with potential explosion shock waves and tornado hazards, especially a frame-integrated impact-resistant airtight tornado valve. Background technique [0002] The explosion shock wave mainly has two stages that will cause greater damage: the first stage is that when the explosion occurs, the center of the explosion will release a shock wave of tens of thousands of atmospheres. Ring force, the pressure of the shock wave decays rapidly as the distance traveled by the shock wave increases. The second stage is that the air at the center of the explosion shrinks to generate negative pressure due to the inertia of the fluctuation, followed by a strong negative pressure wave. When a negative pressure wave is generated, the air pressure inside the building is greater than th...
