When predetermined magnetic attracting force, the diaphragm is moved to closed position by open position.The on and off of the diaphragm is with outside
With internal pressure differential and change, in use, can effectively keep its sealing effect, gas leak phenomenon will not occur, make
With safer and simple in structure.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the magnetic air bleeding valve of people's air defense that the utility model embodiment provides.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are in the premise for not making creative work
Lower obtained all other embodiment, shall fall within the protection scope of the present invention.
Such as Fig. 1, the utility model embodiment provides a kind of people's air defense magnetic air bleeding valve, including a valve seat 10 and it is deformable simultaneously
The diaphragm 20 to resile, the valve seat 10 are installed on a defense equipment 30, are separated out outside an inner space A and one
Portion's space B, the valve seat 10 have a fixed part 11, a ventilating part 13 and one first contact site 12, the contact site in
It is the outside of the ventilating part 13, the ventilating part 13 is used to be vented.
Such as Fig. 1, the diaphragm 20 is fixed on the fixed part 11, is covered on the ventilating part 13, the diaphragm 20
With one second contact site 22, the diaphragm 20 can between a closed position P1 and an open position P2 Deformation Activities, can be with
It is deformed by external force and replys original shape, therefore, it is possible to which under the effect of external force, P1 and open position P2 switchings are lived in closed position
It is dynamic.Closed position P1 refers to that the diaphragm 20 covers the valve seat 10 completely, it is impossible to supply stream and pass through, open position P2 refers to institute
It states and forms venthole between diaphragm 20 and the valve seat 10.The thickness of the diaphragm 20 is by itself and the 11 fixed position of fixed part
It puts towards second contact site 22 and is gradually reduced so that diaphragm 20 sensitively can deform and resile.The diaphragm
20 rounded or fan-shaped or rectangles, the middle part of the diaphragm 20 are fixed on the fixed part 11.
It such as Fig. 1, attracts each other between first contact site 12 and second contact site 22, generates a predetermined magnetic suction
Gravitation.Wherein, first contact site 12 is magnet, and second contact site 22 is iron plate or can be by magnet adsorption
Material.In another embodiment, first contact site 12 for iron plate or can by the material of magnet adsorption, described second
Contact site 22 is magnet.In other embodiments, first contact site 12 and second contact site 22 are magnet.
Such as Fig. 1, the air pressure of 30 inner space A of defense equipment and the difference of the air pressure of exterior space B are defined as real-time pressure
Difference (i.e. the air pressure of 30 inner space A of defense equipment subtracts the air pressure of exterior space B), when real-time pressure difference is more than determined magnetic
Property attraction when, the diaphragm 20 is moved to open position P2 by closed position P1, when real-time pressure difference be not more than determined magnetic
During property attraction, the diaphragm 20 is moved to closed position P1 by open position P2.Predetermined magnetic attracting force is according to real work
Demand is set, that is, changes the material of the first contact site 12 and the second contact site 22 or mutual attraction, when pre-
To determine after magnetic attracting force is provided with, when real-time pressure difference is more than predetermined magnetic attracting force, diaphragm 20 is in the open position P2,
The magnetic exhaust valve opening degassing function of the people's air defense;When real-time pressure difference is not more than predetermined magnetic attracting force, diaphragm 20
P1 in the closed position, the magnetic exhaust valve closure degassing function of the people's air defense.Meanwhile the diaphragm 20 passes through magnetic with valve seat 10
Property attraction combine, can effectively ensure that it, with preferable seal, will not generate gap, use is safer easily.
In conclusion the second contact site 22 of the diaphragm 20 and the first contact site 12 of the valve seat 10 attract each other,
A predetermined magnetic attracting force is generated, the air pressure of 30 inner space A of defense equipment and the difference of the air pressure of exterior space B are defined as reality
When pressure difference value, when real-time pressure difference be more than predetermined magnetic attracting force when, the diaphragm 20 is moved to out by closed position P1
Position P2 is opened, when real-time pressure difference is not more than predetermined magnetic attracting force, the diaphragm 20 is moved to pass by open position P2
Closed position P1.The on and off of the diaphragm changes with pressure differential outwardly and inwardly, in use, can effectively protect
Its sealing effect is held, gas leak phenomenon will not occur, use is safer, and simple in structure.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
