Description
Technical field：
The utility model is related to valve technology field, particularly a kind of ventilation butterfly valve.
Background technology：
Ventilation butterfly valve applies in general to the pipelines such as industry, metallurgy, environmental protection and makees ventilation parameters rate-of flow to be used, prior art
In the composition such as the general valve body of ventilation butterfly valve, valve rod, valve element, the sealing pair of valve rod and valve element typically using a point face sealing means,
Valve element easily causes sealing wear in rotary course, causes leakage；Secondly, valve body typically employs the side of being fixedly connected with valve rod
Formula, valve element is fixed on valve rod, causes the expansion clearance between valve element and valve body small, the card that easy valve body internal cause rising-heat contracting-cold is caused
Dead phenomenon.
Therefore, the utility model proposes a kind of ventilation butterfly valve secondary.
Utility model content：
For defect present in prior art, the purpose of this utility model is just to provide a kind of simple structure, sealing
The good, valve element of energy and valve body are not easy the stuck ventilation butterfly valve caused by rising-heat contracting-cold.
The utility model solves the technical scheme that its technical problem used：One kind ventilation butterfly valve, including valve body, valve
Bar, valve element, it is characterised in that the valve body includes flow channel and flow pass, is provided between flow channel and flow pass
Valve element, valve element is provided with valve rod connecting hole, and valve element is provided with sealing pair near flow channel end with the valve body junction, described close
Seal secondary inclined-plane and constitute face sealing with the inclined-plane of valve body；Valve rod hole is additionally provided with valve body, valve rod one end is through valve rod hole and drives
Device is connected, and the other end is movably connected in body base through the valve rod connecting hole socket bushing on valve element.
Using above technical scheme, the utility model valve element is provided with sealing near flow channel end with the valve body junction
Pair, the inclined-plane of the sealing pair constitutes face sealing with the inclined-plane of valve body, due to being face face by the point face seal en-hancement of prior art
Sealing means, enhance sealing contact surface, reduce leakage；The valve body other end is lived through valve element upper valve lever attachment hole socket bushing
It is dynamic to be connected to body base, due to increased bushing, make the expansion clearance between valve element and valve body big, can effectively prevent because thermal expansion is cold
The stuck phenomenon that contracting is caused.
Used as improvement of the present utility model, the sealing pair is seal washer, and the seal washer gland is fixed on valve element
On flow channel one end.
Using above technical scheme, sealing pair is seal washer, and seal washer is fixed with gland, change, it is easy for installation.
Used as improvement of the present utility model, the valve rod is provided with filler with the junction of valve body upper valve rod aperture, and uses filler
Gland is compressed and constitutes valve stem seal.
Using above technical scheme, filler is provided with the junction of valve rod and valve body upper valve rod aperture, and use gland pressure
It is tight to constitute valve stem seal, it is further ensured that valve seal performance.
Brief description of the drawings：
Fig. 1 is the utility model structural representation.
Specific embodiment：
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole

As shown in figure 1, the utility model provides a kind of ventilation butterfly valve, including valve body (1), valve rod (2), valve element (3), it is special
Levy and be, the valve body (1) includes flow channel and flow pass, and valve element (3), valve are provided between flow channel and flow pass
Core (3) is provided with valve rod connecting hole, and valve element (3) is provided with sealing pair (4) near flow channel end with the valve body (1) junction,
The inclined-plane of the sealing pair (4) constitutes face sealing with the inclined-plane of valve body (1)；Valve rod hole, valve rod (2) are additionally provided with valve body (1)
End is connected through valve rod hole with drive device, and the other end is socketed bushing (5) and is flexibly connected through the valve rod connecting hole on valve element (3)
In valve body (1) bottom, the utility model valve element (3) is provided with sealing pair near flow channel end with the valve body (1) junction
(4), the inclined-plane of the sealing pair (4) constitutes face sealing with the inclined-plane of valve body (1), due to the point face seal en-hancement by prior art
It is face face sealing means, enhances sealing contact surface, reduces leakage；Valve body (1) other end passes through valve element (3) upper valve lever attachment hole
Socket bushing (5) is movably connected in valve body (1) bottom, due to increased bushing (5), makes the expansion between valve element (3) and valve body (1)
Gap is big, can effectively prevent the stuck phenomenon caused by rising-heat contracting-cold.
The sealing pair (4) is seal washer, and the seal washer gland (6) is fixed on valve element (3) near flow channel
On one end, sealing pair (4) is seal washer, and seal washer is fixed with gland (6), is changed, easy for installation；The valve rod (2) with
The junction of valve body (1) upper valve rod aperture is provided with filler (7), and gland (8) is compressed and constitutes valve stem seal, is further ensured that valve
Door sealing performance.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
