Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
Air-flow butterfly valve as shown in Figures 1 to 3, including pipeline 3, bonnet 4, valve plate 2, center-pole 1, handle 8, the and of fixed block 5
Sealing ring 6.Bonnet 4 is located at the top of pipeline 3, and fixed block 5 is fixed on the inwall of bonnet 4, and center-pole 1 passes through fixed block 5, fixed block 5
Center-pole 1 can be made more stable, the two ends of center-pole 1 connect handle and valve plate 2 respectively, valve plate 2 is located inside pipeline, and handle is located at
The top of bonnet 4.
Bonnet is fixed on above pipeline by fastener 40 (such as bolt screw), facilitates the dismounting and installation of bonnet, when
Valve internal occurs after damaging, and can be taken away valve casing 4 by fastener 40, so as to be overhauled to the component in pipeline, greatly
The big service life for adding valve, reduces cost.
Valve plate 2 in the present embodiment is circular sheet metal valve element, drives valve plate 2 to rotate by swing handle, is realized
The break-make of gas in pipelines.
Center-pole 1 is slidably connected with bonnet, fixed block 5, and center-pole 1 can drive handle and valve plate to move up and down.Center-pole 1
Outer wall be further fixed on baffle ring 10, between baffle ring 10 and fixed block 5 be provided with spring, spring housing be located at the outer wall of center-pole 1, valve plate 2
Flow-stopping plate 90 (flow-stopping plate is made up of air-locked material such as elastic caoutchouc), baffle are provided with towards the pipeline of the side of water inlet 31
Plate 90 is in " ◎ " shape, its section is curved and is brought into close contact with the outer wall of valve plate 2, annular flow-stopping plate 90 and the more easy sticker of valve plate 2
Close, sealing property is more good.
Flow-stopping plate 90 is arranged at the inflow pipe side of valve plate 2, when valve plate 2 is closed, and the pressure in inflow pipe is higher than stream
At pipe, therefore flow-stopping plate 90 increases air-tightness by by pressure pushing down and be close to the surface of valve plate 2 tightly.
As shown in figure 4, valve plate 2 and through hole are circle, the diameter difference of the through hole and valve plate 2, which is less than on center-pole, to be moved down
Dynamic ultimate range.The maximum of the movement spacing of valve plate 2 subtracts the diameter difference of through hole and both valve plates 2, when as valve plate 2 is pushed
The gap length of generation, the size in gap determines air-flow velocity.
The side wall for pressing pressure type handle is provided with lever 80, and convenient use person rotates to handle, and next can also be used for differentiating
The open/close states of valve element.
The pipeline of the lower section of valve plate 2 is provided with attached chamber 9, and attached chamber 9 can increase the distance that valve plate 2 is moved up and down, if lacking attached
Chamber 9, then need the increase by a relatively large margin by the inner diameter progress of pipeline, so that valve plate 2 is moved up and down, therefore set up attached chamber
After 9, the diameter of pipeline can be greatly reduced.
The air-flow butterfly valve of the present embodiment has 2 kinds of occupation modes：High frequency break-make stream mode and lasting through-flow mode.
Continue through-flow mode：
As shown in figure 1, butterfly valve is in the state closed, under the action of the spring, spring contradicts baffle ring 10 and fixed block 5,
Because fixed block 5 is fixed on bonnet inwall, baffle ring 10 is mortgaged by spring, and valve plate 2 is completely obscured by the through hole on flow-stopping plate 90,
In the presence of air pressure, the surface for fitting in valve plate 2 of flow-stopping plate 90 tightly, air-tightness is strong, is difficult gas leakage.
As shown in figure 3, by rotating handles 8, the angle that valve plate 2 is turned in Fig. 3, valve element is opened, and gas can be smooth
Pass through.
High frequency break-make stream mode：
As shown in figure 1, handle is turned into Fig. 2 positions, valve element is closed, and fluid can not pass through.
As shown in Fig. 2 now by pressing pressure handle hand 8, drive valve plate 2 and baffle ring 10 to be pressed downward center-pole 1, valve plate 2 with
Gap (as shown in Figure 4) is produced between flow-stopping plate 90, while the compression spring of baffle ring 10, now valve plate 2 and the top of flow-stopping plate 90 are produced
Fluid in raw certain gap, pipeline is flowed by gap, and gas flows out out of butterfly valve.
When hand no longer presses pressure handle hand, baffle ring 10 is moved up under the action of the spring to set back, and drives center-pole
1st, valve plate 2 and handle are together moved up, and valve plate closes the through hole on flow-stopping plate 90 again under the action of the spring, now valve
Closed mode is again at, valve stops ventilation.
Air-flow butterfly valve in the present embodiment, in addition to can be with break-make gas, can also carry out break-make and control to liquid fluid
System, the present embodiment and without excessive restriction.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
