Abstract
A kind of closed exhaust valve of superpressure, including valve and valve disc, valve disc are arranged in valve, in addition to O-ring seal, O-ring seal are arranged in the notch of valve disc, and when exhaust valve is closed, O-ring seal is between valve disc and valve.Beneficial effect is caused by the utility model：Between valve and valve disc, O-ring seal is with the addition of, ensure that the tightness of exhaust valve, has reached the technical requirements and acceptance criteria of air defense basement.Meanwhile installation and debugging are simple, processing cost is reduced.
Description
Technical field
A kind of air defense basement ventilation equipment device is the utility model is related to, it is more particularly to a kind of to be arranged on air defense basement
The closed exhaust valve of superpressure on ventilation shaft, valve row is opened by air pressure when gas superpressure in civil air defense constructions and installations main body, used
To realize, air pressure is normal in civil air defense constructions and installations main body.
Background technology
Exhaust valve is the important device of air defense basement, and it is arranged on ventilation shaft, when gas in civil air defense constructions and installations main body
During body superpressure, valve is opened by air pressure and is vented.The structure of original exhaust valve is to be set to integral lever and valve with valve disc
The connection for two pieces of raised plates that door is provided with is connected by axle rod, framed amount, so as to cause valve and valve disc connecting portion not
Tightly, the technical requirements of air defense basement are not reached, it is difficult to pass through the acceptance of work.
My exhaust valve patent of company 201220283109.7, axle rod connected mode is changed to cone pin and tapered cup nut connects
Mode is connect, solves valve and the imprecise problem of valve disc connecting portion.Process is used by practice, is also sent out on inspection of hermetic seal
Show some problems, i.e. imprecision when valve is crimped with valve disc, there is gap, study and find through technical staff, valve and valve disc
Contact surface for it is hard coordinate contact, when this requires the processing in valve and valve disc contact surface, flatness is at a relatively high, otherwise, valve
Imprecision phenomenon just occurs when being crimped with valve disc in door.The deficiency of high processing costs and installation and debugging complexity is brought therewith.
The content of the invention
In view of the shortcomings of the prior art, the utility model, which provides one kind, has stronger tightness, meets anti-vacant lot
The closed exhaust valve of superpressure of the technical standard requirement of lower room, between valve and valve disc, with the addition of O-ring seal, solve existing
Have insufficient existing for technology.
The utility model to achieve the above object, is adopted the technical scheme that：A kind of closed exhaust valve of superpressure, including
Valve and valve disc, valve disc are arranged in valve, it is characterised in that：Also include O-ring seal, the O-ring seal is arranged on valve disc
Notch in, when exhaust valve is closed, O-ring seal be between valve disc and valve.
Beneficial effect is caused by the utility model：Between valve and valve disc, O-ring seal, the row of ensure that with the addition of
The tightness of gas valve, the technical requirements and acceptance criteria of air defense basement are reached.Meanwhile installation and debugging are simple, reduce
Processing cost.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
As shown in Figure 1, 2, the closed exhaust valve of a kind of superpressure, including valve 1 and integral lever 2-1 is set to valve disc 2,
Valve disc 2 is arranged in valve 1, and weight 3 is arranged on lever 2-1 low side, in addition to O-ring seal 4.
O-ring seal 4 is bonded in the notch of valve disc 2, and when exhaust valve is closed, O-ring seal 4 is in valve disc 2 and valve
Between door 1, ensure that valve disc is closed tightly with valve in the presence of weight, open and close flexible.
Utility model works principle：Valve is acted on valve disc by superpressure closed gas pressure, is driven lever, is made valve
Reach automatic opening purpose, in the nutating action power of weight 3, valve disc 2 is pushed down valve 1 by O-ring seal 4, play closed work
With when distress resolves, valve disc relies on lever balance theory, is returned to original position, that is, reaches the purpose of closing automatically.
