Abstract
The utility model relates to the field of heating and ventilation products, and in particular relates to a vent valve which is applied to industrial, military or civil facilities and the like in situations for protecting high-strength air impact compression. A compression-resistant framework of a vent valve vane comprises a vent valve framework which is provided with a cylindrical fixed structure with a holding space, an impact receiving air inlet and a protected air inlet, longitudinal reinforcing ribs are arranged in the holding space and respectively provided with a side edge I, and the side edges I are positioned on one side close to the impact receiving air inlet and provided with grooves I. The compression-resistant framework of the vent valve vane solves the problem that a conventional vane deforms and is damaged or cannot close due to high-strength atmospheric pressure impact.
Description
Technical field
The utility model relates to HVAC series products field, especially needs occasion that high strength air percussive pressure is protected, comprises industry, the ventilation valve that military installations or house owed by a citizen facility etc. use.
Background technology
In prior art, the ventilation valve that adopts when high strength air percussive pressure is protected generally adopts the mode of moving vane rotation to make blade cut out or open.When normal the ventilation, apply certain torsion by spring mechanism to blade, make it open to set angle, ventilation function is provided.When being subject to shock wave and impacting, the torsion that produces when the pressure that puts on blade is during greater than design torsion, and blade is closed, and prevents that surge from entering shielded Architectural Equipment.
Because blade is sheet member, and certain length is arranged, when bearing powerful pressure, easily deform, cause that ventilation valve lost efficacy, and can not effectively protect facility and the personnel of building.
The mainstream solution of the anti-pressure ability of reinforced blade all adopts inverted V-shaped hollow steel plate.Then, when the large-sized ventilation valve of needs, even the inverted V-shaped blade is not resisted high-intensity pressure because length has greatly enough intensity yet.And when adopting the scheme of common reinforcement, press close to blade as reinforcement, can hinder blade rotary; And when leaving the blade certain distance, can not play again the effect that prevents deformable blade, thereby can guarantee that blade rotary can prevent that again the impaired distortion of blade from being the difficult problem that industry needs to be resolved hurrily always.
The utility model content
Goal of the invention of the present utility model is to provide a kind of ventilation valve blade (including but not limited to volume damper, shock wave resistance valve and anti-explosive valve etc.) deformed damaged or can't closed ventilation valve blade resistance to compression framework after impacted by high strength air pressure that prevents.
Goal of the invention of the present utility model is achieved in that
Ventilation valve blade resistance to compression framework; comprise the ventilation valve framework; tubular fixed structure with an accommodation space; have to meet and impact air port and a protected air port; be provided with reinforcement longitudinally in described accommodation space; described reinforcement longitudinally has a lateral margin first, and described lateral margin first is positioned near the described side of impacting the air port of meeting, and described lateral margin first is provided with the groove first.
Further, also be provided with horizontal reinforcement in described accommodation space; Be positioned at described protected air port one side, described horizontal reinforcement is fixedly connected with described reinforcement longitudinally.Horizontal reinforcement and longitudinally the connected mode of reinforcement can be: horizontal reinforcement is welded and fixed with reinforcement longitudinally; Also horizontal reinforcement is provided with groove second, and reinforcement is arranged in described groove second longitudinally, and horizontal reinforcement connects and fixes with reinforcement longitudinally.
Further, be provided with stopping means on the ventilation valve framework in accommodation space.
The utility model is equiped with the blade strengthening part in the accommodation space of ventilation valve framework, i.e. reinforcement and horizontal reinforcement longitudinally, and reinforcement and horizontal reinforcement have prevented from causing distortion when blade bears powerful shock wave effectively longitudinally.And offer the groove first longitudinally on reinforcement, the groove first guarantees that blade can freely rotate in the accommodation space of ventilation valve framework, blade in rotation process with reinforcement mutually noninterfere longitudinally.And the purpose of stopping means is to set the rotational angle of a limit to blade, avoids rotating excessively causing ventilation valve when being subject to large shock wave, and blade can not be well closed.
The utility model has solved large-scale ventilation valve in the problem of High Voltage lower blade distortion, and can adjust as required the density of strengthening part, thereby can satisfy the protection needs of any strength impact pressure of reply.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further
In conjunction with Fig. 1 to Fig. 3 as can be known; Ventilation valve blade resistance to compression framework comprises ventilation valve framework 1, reinforcement 2 and horizontal reinforcement 3 longitudinally.The tubular fixed structure of ventilation valve framework 1 for being in turn connected to form by upper beam 14, right beam 15, underbeam 16, left beam 17 has accommodation space 11, is provided with one and meets impact air port 12 and a protected air port 13.Be provided with reinforcement 2 longitudinally in accommodation space 11.The two ends of reinforcement 2 are fixedly connected with underbeam 16 with upper beam 14 respectively longitudinally.
Also be provided with horizontal reinforcement 3 in accommodation space 11.The two ends of reinforcement 2 are fixedly connected with right beam 15 with left beam 17 respectively longitudinally.Horizontal reinforcement 3 is positioned at protected air port 13 1 sides, and longitudinally between reinforcement 2 by being welded and fixed.Horizontal reinforcement 3 is provided with groove second, and reinforcement 2 is arranged in described groove second longitudinally, and horizontal reinforcement 3 connects and fixes with reinforcement 2 longitudinally.
Further, use the ventilation valve of ventilation valve blade resistance to compression framework, also comprise blade 4.
Blade 4 rotatably is fixed on ventilation valve framework 1 by rotating shaft 6.The other end of rotating shaft 6 is connected with spring mechanism, and spring mechanism is positioned at outside accommodation space 11, and is fixed on ventilation valve framework 1.Also be provided with stopping means 7 on ventilation valve framework 1, stopping means 7 is limiting plate, and the effect of stopping means 7 is to set the limiting value of a rotation for blade 4, avoids blade 4 to rotate over preset value and causes the ventilation valve closure not tight.
The purpose of groove first 22 reduces blade 4 and the radius of gyration between reinforcement 2 longitudinally, when blade 4 is closed, groove first 22 can make the blade 4 of closure and reinforcement 2 applyings longitudinally, the space between the blade 4 of minimizing groove first 22 and closure, the anti-impact force of raising blade 4 with imitating.
As long as in the rotation that does not hinder blade 4, and can reduce longitudinally between reinforcement 2 and under the prerequisite in the gap between the blade 4 of closure, groove first 22 can be any shape.
