Description
Technical field
The present invention relates to a kind of HVAC special equipment of building, more particularly to a kind of shock wave resistance valve.
Background technology
When carrying out safe design for some buildings, it is necessary to consider corresponding HVAC facilities design, the HVAC of building
Need to set impact resistance valve on special equipment, in order to avoid the negative pressure of the generations such as explosion wave, typhoon or cyclone, to building
Build the equipment in thing or personnel cause damage, it is necessary to which the hole installation inside and outside connecting building thing is when outside produces certain negative pressure
The shock wave resistance valve that moment closes.In order to avoid the positive pressure that explosion wave produces causes to damage to the equipment in building or personnel
Wound is, it is necessary to shock wave resistance valve moment closing when outside produces certain positive pressure of the hole installation inside and outside connecting building thing.For
Achieve the purpose that can to close moment under positive pressure, negative pressure, it is necessary to a kind of shock wave resistance valve with bidirectional protective effect, once
When above-mentioned positive pressure or negative pressure condition occur, shock wave resistance valve needs moment to close, and separates interface channel inside and outside building, avoids building
Build pressure in thing rise sharply or rapid drawdown and cause unnecessary loss, when that explosion, typhoon or cyclone etc. may occur on building
Acted on bidirectional protective.
The shock wave resistance valve of the prior art has certain limitation：1st, close valve disc by axis with spring to be connected, spring
Power make it that closing valve disc maintains certain angle, and closing valve disc can only one-directionally rotate, and be closed with valve body, separate shock wave.Work as impact
Ripple acts on valve disc the other way around or cyclone forms suction function when valve disc, and valve disc cannot be closed with valve body, therefore
Shock wave or negative pressure can not be separated.2nd, after valve disc is closed, after positive pressure or negative pressure disappear, it is impossible to automatically open up, be unable to reach
Bidirectional protective, also can not automatic returning nature.3rd, it is mostly to be assemblied to form by component welding, there are a large amount of pads and weldering
Quality problems are connect, influence the intensity and aesthetics of valve.4th, movable part quantity is more, and safety coefficient is low.5th, valve disc and bullet are used
Spring connects, and maintains normal ventilation, and valve disc against the force of the spring is closed with valve body.Result in the need for closing slow, nothing during moment closing
Method is fast and effective to play a protective role.
The content of the invention
The purpose of the present invention is：A kind of shock wave resistance valve that can solve above-mentioned existing issue is provided, valve disc passes through cushion
Piece is realized with valve body to be flexible coupling, and under positive pressure and suction function, valve disc can close, and after positive pressure or suction function disappear,
Valve disc can automatically open up, and have bidirectional protective effect.Valve body is by an extrusion forming, without any welding.
The technical scheme is that：Shock wave resistance valve, it is characterised in that：Shock wave resistance valve, including it is valve body, flexible
Valve disc is closed, the valve body is equipped with ventilation guide groove, and the closing valve disc is arranged in the valve body cavity body and can move, described
Close valve disc both ends and be equipped with elastomeric pad, the closing valve disc passes through the elastomeric pad and the valve body contact, the closing
When valve disc is subject to external force, its valve disc can be bent, and the elastomeric pad can stretch, normally during ventilation, at the closing valve disc
In the valve body ventilating opening centre position；When positive pressure shock wave is in the closing valve disc, the closing valve disc occurs curved
Song, the degree of crook of the closing valve disc is consistent with valve body cavity curvature, and the closing valve disc is closed with valve body；When explosion is produced
When producing suction function in the closing valve disc, the closing valve disc is curved round about for raw negative pressure shock wave or cyclone
Song, closes with valve body；When active force disappears, the closing valve disc relies on its own resilient, recovers to home position.
Preferably, the closing valve disc can only be moved back and forth due to the elastomeric pad and the valve body restriction effect,
It cannot rotate, and the valve disc can bend and be closed with valve body.
Preferably, the valve body is equipped with one or more ventilation guide grooves, and each guide groove of divulging information is separate.
Preferably, the valve body is divided into two parts up and down, using aluminium alloy or stainless steel, by it is casting integrated into
Type, forms multigroup ventilation guide groove and cavity, and guide groove is cuboid-type, and cavity geometry is arch, and guide groove effect is guiding shock wave
Direction and airflow direction, make it act on the power of closing valve disc uniform.
Preferably, two parts by resilient pin and are bolted the valve body up and down.
Preferably, the valve body further includes valve body intermediate connector, valve end connector, the body top and bottom
Boss is equipped with, for placing the valve body and valve body intermediate connector or end coupling.
Preferably, the valve disc of closing uses the stainless steel with superior elasticity.
Preferably, frame, press strip are further included, there is bolt hole at the intermediate connector, press strip, end coupling both ends,
The intermediate connector is positioned on the body top or bottom boss, bolt hole and the valve body bolt of the intermediate connector
Hole matches, and for being connected between valve body, the press strip is used to valve body being fixed on frame, and bolt passes through press strip bolt hole, valve body
And intermediate connector bolt hole, valve body is fixed on frame, the end coupling is fixed for whole valve both ends, bolt
Through press strip bolt hole and end coupling bolt hole, valve both ends are fixed on frame.
It is an advantage of the invention that：
1st, under positive pressure and suction function, valve disc can close, and after positive pressure or suction function disappear, valve disc can be certainly
It is dynamic to open, there is bidirectional protective effect.
2nd, valve body and valve disc are by once extruding either die casting or moulding by casting, without any welding.Process is saved, is improved
Work efficiency.
3rd, ventilation guide groove is cuboid-type, and cavity geometry is arch, and guide groove effect is guiding shock wave direction and air-flow side
To, make its act on close valve disc power it is uniform.
4th, during normal ventilation, close valve disc and body cavity centre position is in the case where no external force acts on.When explosion produces just
Shock wave is pressed when valve disc is closed, valve disc is closed and bends, shift to valve body side, closed with valve body, separate building
Internal and external channel.When explosion produces negative pressure shock wave or cyclone when producing suction function when valve disc is closed, closing valve disc is sent out
Raw bending, shifts to valve body opposite side, is closed with valve body, separates building internal and external channel.During normal ventilation, when active force disappears
When, valve disc recovers to home position.It can have the function that bidirectional protective and automatically reset, beneficial to air circulation, not employment
Power, which is gone to supervise and acted, can have the function that bidirectional protective and automatic ventilation, improve automation.
5th, number of components is few, simple in structure, and safety coefficient is high.
