Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Air-flow butterfly valve as shown in Figures 1 to 3, comprises pipeline 3, valve gap 4, valve plate 2, center-pole 1, handle 8, fixed block 5 and seal ring 6.Valve gap 4 is positioned at above pipeline 3, and fixed block 5 is fixed on valve gap 4 inwall, and center-pole 1 is through fixed block 5, and fixed block 5 can make center-pole 1 more stable, and center-pole 1 two ends connect handle and valve plate 2 respectively, and valve plate 2 is positioned at pipe interior, and handle is positioned at above valve gap 4.
Valve gap is fixed on above pipeline by fastening piece 40 (as bolt screw etc.), facilitate dismounting and the installation of valve gap, after there is damage in valve internal, by fastening piece 40, valve casing 4 can be taken away, thus the assembly in pipeline is overhauled, considerably increase the working life of valve, reduce cost.
Valve plate 2 in the present embodiment is circular sheet metal spool, drives valve plate 2 to rotate, realize the break-make of gas in pipelines by rotatory handling.
Center-pole 1 and valve gap, fixed block 5 are slidably connected, and center-pole 1 can drive handle and valve plate to move up and down.The outer wall of center-pole 1 is also fixed with baffle ring 10, spring is provided with between baffle ring 10 and fixed block 5, center-pole 1 outer wall is located at by spring housing, valve plate 2 is provided with flow-stopping plate 90 (flow-stopping plate is made up of air-locked materials such as elastic caoutchoucs) in the pipeline of water inlet 31 side, flow-stopping plate 90 is in " ◎ " shape, its cross section is curved and fit tightly with valve plate 2 outer wall, and flow-stopping plate 90 and the valve plate 2 of annular are more easily fitted, and sealability is more good.
Flow-stopping plate 90 is arranged at the inflow pipe side of valve plate 2, when valve plate 2 is closed, the pressure in inflow pipe higher than outflow tube place, therefore flow-stopping plate 90 by by pressure tightly push down and be close to valve plate 2 surface, increase tightness.
As shown in Figure 4, valve plate 2 and through hole are circle, and the diameter difference of described through hole and valve plate 2 is less than the ultimate range that center-pole moves up and down.The maximum value of valve plate 2 moving interval deducts through hole and the diameter difference both valve plate 2, and be the gap length produced when valve plate 2 presses down, the size in gap determines air-flow velocity.
The sidewall pressing pressure type handle is provided with lever 80, and person easy to use rotates handle, secondly also can be used for the open/close states differentiating spool.
Pipeline below valve plate 2 is provided with attached chamber 9, and attached chamber 9 can increase the distance that valve plate 2 carries out moving up and down, if lack attached chamber 9, then need the increase carried out by the inner diameter of pipeline by a relatively large margin, move up and down for valve plate 2, after therefore setting up attached chamber 9, significantly can reduce the diameter of pipeline.
The air-flow butterfly valve of the present embodiment has 2 kinds of usage mode: 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 of cut out, under the action of the spring, spring conflict baffle ring 10 and fixed block 5, because fixed block 5 is fixed on valve gap inwall, baffle ring 10 is mortgaged by spring, through hole on flow-stopping plate 90 covers by valve plate 2 completely, under the influence of air pressure, and flow-stopping plate 90 surface fitting in valve plate 2 tightly, tightness is strong, not easily leaks gas.
As shown in Figure 3, by rotating handles 8, valve plate 2 is turned to the angle in Fig. 3, spool is opened, and gas can pass through smoothly.
High frequency break-make stream mode:
As shown in Figure 1, handle is turned to Fig. 2 position, spool is in closed condition, and fluid cannot pass through.
As shown in Figure 2, now by pressing pressure handle hand 8, driven by center-pole 1 valve plate 2 and baffle ring 10 to pressing down, gap (as shown in Figure 4) is produced between valve plate 2 and flow-stopping plate 90, baffle ring 10 Compress Spring simultaneously, now produce certain gap above valve plate 2 and flow-stopping plate 90, the fluid in pipeline is flowed by gap, and gas flows out in butterfly valve.
When hand no longer presses pressure handle hand, baffle ring 10 moves up under the action of the spring and sets back, and drives center-pole 1, valve plate 2 and handle together to move up, and valve plate closes the through hole on flow-stopping plate 90 under the action of the spring again, now valve is in closed condition again, and valve stops ventilation.
Air-flow butterfly valve in the present embodiment, except can except break-make gas, can also carry out break-make and control to liquid fluid, the present embodiment carry out too much restriction.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
