Abstract
The invention discloses an anti-explosive valve which is formed by unit valve bodies (1) combined together. The surface of each unit valve body (1) is provided with an air outlet (2); a bottom plate (3) is arranged in the unit valve body (1); a slide block (4) is arranged on the bottom plate (3); and the slide block is elastically connected with the bottom plate (3). With the structure, the invention can prevent explosive shock waves from entering the inside of a building from the air outlet while meeting the requirement of ventilation, thereby protecting indoor people and equipment.
Description
Technical field
The present invention relates to a kind of heating and ventilating discipline equipment, especially relate to a kind of anti-explosive valve that is installed on explosion resistant structure constructure ventilation mouth end.
Background technology
At present, control centre in petrochemical industry and medical factory, electric control chamber, laboratory and experimental rig, production department causes huge infringement for avoiding accidental explosion, building structure must consider to adopt explosion resistant structure, for example antiknock wall, blast-resistant door or the like, the employing that has is provided with the damping reinforcing rib structure in antiknock wall, blast-resistant door, the employing all steel matter reinforced door body structure that has.Suchlike explosion resistant structures such as antiknock wall, blast-resistant door can be protected in traditional bomb, and antiknock building and indoor personnel and the safety of equipment also can stop explosion wave that the place of safety is caused damage simultaneously.But, because the ventilation system that is installed in the building does not reach identical antiknock rating, when the antiknock building external is blasted, explosion wave can enter interior of building from being installed on architectural ventilation opening end, thereby indoor personal safety and equipment are caused damage, lead to major accident and economic loss.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of can satisfy simultaneously air-conditioning requirement anti-explosive valve.
Technical problem to be solved by this invention is achieved by the following technical solution: it comprises that the unit valve body combines, and the surface of described unit valve body is provided with air outlet, is provided with base plate in the unit valve body, and base plate is provided with slide block, and slide block is connected with base plate elasticity.
Unit of the present invention valve body is that housing in row combines.
The said structure that the present invention adopts owing to be provided with air outlet on the surface of unit valve body, can prevent that explosion wave from entering interior of building from air outlet, thereby can protect the indoor person and device security when satisfy air-conditioning requirement.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Figure 1 shows that the front view of unit of the present invention valve body
Figure 2 shows that the cut-away view of Fig. 1
The specific embodiment
By accompanying drawing as can be known, this anti-explosive valve comprises that unit valve body 1 combines, and the surface of described unit valve body 1 is provided with air outlet 2, is provided with base plate 3 in unit valve body 1, and base plate 3 is provided with slide block 4, and slide block 4 is connected with base plate 3 elasticity, and elasticity connects the main spring that adopts and connects.Valve body can be made by high-tensile structural steel, so that anticorrosive fully.Described unit valve body 1 can be for housing in row combines, and specifically the needs according to the client are the valve body of different line numbers of customization and columns.Anti-explosive valve is installed in body of wall and meets quick-fried direction, can vertically install, and also can laterally install.When selecting anti-explosive valve for use, determine that the valve body of different line numbers and columns just can meet the demands according to its ventilation and surperficial pressure.According to the size of valve body, we can determine the body of wall size that punches.Moment by taking place in blast in anti-explosive valve, and whether the size of the impact force of bearing on the unit area decides the anti-explosive valve slide block to close with the elastic deformation between slide block and the base plate, and the time of closing.When the antiknock building external was blasted, under the effect of explosion wave, slide block and base plate fit together, and anti-explosive valve is closed immediately automatically, and the explosion wave retaining outdoor, is prevented that shock wave from causing damage to indoor personal safety and equipment.The antiknock rating of anti-explosive valve is equal or higher with the antiknock rating of antiknock wall at least.
Claims (2)
1, a kind of anti-explosive valve comprises that the unit valve body combines, and it is characterized in that the surface of described unit valve body is provided with air outlet, is provided with base plate in the unit valve body, and base plate is provided with slide block, and slide block is connected with base plate elasticity.
2, a kind of anti-explosive valve according to claim 1 is characterized in that described unit valve body is that housing in row combines.
