Description
Technical field
The present invention relates to the heating and ventilating equipment of building fresh air inlet and wind exhausting outlet, is especially in the presence of potential explosion wave
And a kind of fresh air inlet and the ventilation valve of wind exhausting outlet, especially framework integrated form shock resistance of the building of tornado harm
Closed spout air-valve.
Background technology
Explosion wave mainly has two stages to produce larger broken ring：First stage is explosion center point when blast occurs
The shock wave of tens of thousands of atmospheric pressure is released therewith, and shock wave, at a high speed to moving around, has very big in sphere form to object
Impact cutting ring power, with the increase of shock wave displacement, the pressure of shock wave can decay rapidly.Second stage is explosion center
There is air shrinkage and produce negative pressure in the air of point, incident is once strong suction wave due to the effect of inertia for fluctuating.Negative pressure
When ripple is produced, air pressure is more than outdoor air pressure in building, so as to produce the thrust of a from-inner-to-outer.The suction wave of some strength is same
Sample can cause brokenly ring to facility in building, particularly when ventilation valve is close by explosion center.
Tornado is a kind of strong, air swirl of small range, often has air under the weather conditions of extremely unstable
What strong convection was moved and produced, attack scope is less, but destructive power is very big.Because it is an air swirl, for building
The effect of thing is probably the malleation of a high intensity, it is also possible to the negative pressure of a high intensity, if do not stopped, can be to building
Build facility in thing to damage.
The existing antiknock class air-valve for being used on the market mostly is three types, specific as follows：
As shown in figure 1, the anti-shock wave resistance air-valve of existing array parallel motion, adopts 1 to 3 section for side more
The valve element A2 of shape, circle or other shapes, is closed and is opened vent passages by way of Qian Hou parallel motion.Positive normal open
During wind, valve element A2 is in the intermediate equilibria position of valve A 1, there is provided ventilation function.When there is blast impulse or tornado to attack,
Putting on the shock wave pressure of valve element A2 closes valve element, stops that shock wave or tornado enter building or ventilating system is protected
The side of shield；When shock wave or tornado switch to negative pressure from malleation, valve element reduces vent passages to another lateral movement, until
Negative pressure makes valve element close vent passages.But such air-valve is less due to vent passages space, ventilation rate is low, in the face of big ventilation
Demand when, in a large number cumulative valve module units, cause product cost to raise.When valve element A2 contacts closing with valve A 1, in processing work
Contact surface gap cannot be completely eliminated in skill, causes air-tightness poor.
As shown in Fig. 2 Wind Volume shock wave resistance air-valve, more using one or more monolayers or the valve element of double-deck rectangular thin plate
B1 be arranged in parallel, by setting valve element B1 open angles to closing angle simultaneously rotary motion, so as to realize the unlatching of vent passages
And closing.During normal ventilation, valve element B1 is opened to setting opening angle, there is provided ventilation function.When there is blast impulse, apply
Valve element is closed in the shock wave pressure of valve element B1, stops that shock wave enters building or the shielded side of ventilating system.But
It is that such air-valve ventilation is larger, but is merely able to unilateral shock resistance, when there is possessing the situation of destructive negative pressure, such as spout
Wind, then cannot play the effect of protective structure inner facility safety.Secondly, when valve element B1 is closed, sealing is by valve
Core B1 directly contacts realization sealing with valve element B1, causes sealing poor.Furthermore, when shock wave pressure is larger, valve element B1
Middle support force not enough, is easily deformed.Furthermore, valve element B1 is not directly connected to spring B 2, but is performed by rotating
Mechanism B3 is connected again with spring B 2, because the gap of rotary actuator B3 connections is formed with the cumulative error closed, causes this
Certain rocking is had after type valve core assembling.
As shown in figure 3, circular shock wave resistance air-valve, more using middle one circular valve element, by Qian Hou parallel motion
Vent passages are closed and opened to mode.During normal ventilation, equilbrium positions of the valve element C1 in valve body C2, there is provided ventilation work(
Energy.When there is blast impulse or tornado to attack, putting on the shock wave pressure of valve element C1 closes valve element, stops shock wave
Or tornado enters building or the shielded side of ventilating system；When shock wave or tornado switch to negative pressure from malleation, valve
Core reduces vent passages to another lateral movement, until negative pressure makes valve element close vent passages.But such air-valve due to profile compared with
Greatly, the ventilation of unit area is less than normal；Mounting means is single, it is necessary to installed using casting type；Under identical ventilation requirement cost compared with
It is high；Valve element C1 contact with valve body C2 closing when, contact surface gap cannot be completely eliminated in processing technique, cause air-tightness compared with
Difference.
Therefore, it is equal in two stages of malleation impact and negative pressure impact how when the blast impulse of higher level is run into
Facility in building and building can well be protected, the demand of Wind Volume ventilation can be met, bilateral can be realized again
Shock wave resistance, and become industry technical barrier urgently to be resolved hurrily with preferably sealing.
