Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of Pneumatic vacuum butterfly valve, including valve body 1, valve rod 3, crank 5, valve plate 6, connector 9, support
10 and cylinder 11.Setting valve rod 3 in valve body 1,3 one insertion valve bodies 1 of valve rod, other end passes through valve body 1 to insert crank 5, valve rod 3
Outer socket valve plate 6, as shown in Figure 3,4, by two boards body 601 and the valve rod hole 602 that passes through for valve rod 3 is constituted valve plate 6, valve body 1
Sealing ring 2 is set and valve plate 6 between, and valve plate 6 is integral forming structure.As shown in Figure 5,6, sealing ring 2 circle body opens up and supply valve
The sealing collar aperture 201 that bar 3 passes through, sealing ring 2 both ends of the surface are respectively cooperating with arranging an o type sealing ring 401, in sealing collar aperture 201
Two the 2nd o type sealing rings 402 of setting, valve rod 3 upper end arranges two the 3rd o type sealing rings 403 with valve body 1 junction.This reality
Pass through holding screw 7 with new valve plate 6 and valve rod 3 fixing.Cylinder 11 is supported by the support 10 being connected on valve body 1, cylinder
11 are connected with crank 5 by connector 9, and the key 8 that crank 5 passes through to arrange between the two with valve rod 3 is connected.
Valve body 1 of the present utility model adopts foundry goods, the direct casting of flange bolt hole, and advantage is to mitigate valve body 1 weight
Amount, and only need to process thorax and valve rod hole 602 in valve body 1, decrease manufacturing procedure, the production greatly reducing valve becomes
This.
Valve plate 6 of the present utility model is monoblock type foundry goods it is only necessary to process sealing surface, easy to process, and plate body 601
Between without mode connects for screw, decrease valve partses, while reducing valve cost, enhance stability during valve switch.
Sealing ring 2 of the present utility model is formed using overall compacting, can wrap up thorax in whole valve body 1, sealing ring 2 two ends
Face is respectively cooperating with being provided with an o type sealing ring 401, two the 2nd o type sealing rings 402 of setting, the 2nd o in sealing collar aperture 201
Space between type sealing ring 402 sealing sealing collar aperture 201 and valve rod 3；It is provided with an o type sealing ring 401 and the 2nd o type is close
The sealing ring 2 of seal 402 ensures the sealing property of whole valve, ensures that runs stablizes, extends the service life of whole valve,
And after sealing ring 2 two ends are provided with an o type sealing ring 401, integral thickness increases, and makes sealing ring 2 difficult for drop-off.
