Description
Technical field
The utility model is related to a kind of butterfly valves, more precisely, being a kind of wafer type hard seal butterfly valve.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to closure member（Flap or butterfly plate）For disk, a kind of valve of open and close is reached around valve shaft rotation.Valve can
For controlling the various types such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium
The flowing of fluid.Cut-out and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
It is rotated around the axis of its own, to achieve the purpose that keying or adjusting.The butterfly valve that industry generally uses at present is due to flap
Often leakproofness is not good enough for reciprocal overturning friction, and then influences the service life of butterfly valve.
Utility model content
The utility model is mainly the technical problem solved present in the prior art, is sealed firmly to provide a kind of wafer type
Butterfly valve.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：
A kind of wafer type hard seal butterfly valve is rotationally equipped with a valve rod, the end of valve rod is set including a valve body on valve body
There is a control handle, is equipped with a shaft in valve body, is connected by teeth between shaft and valve rod, one is fixedly connected on the body of rod of shaft
Bearing is rotationally equipped with a retainer plate on bearing, is fixedly connected with one first valve plate on retainer plate, a support is additionally provided on valve body
, it is rotationally equipped with a supporting rod on support base, one second valve plate, the first valve plate and the second valve plate are fixedly connected on supporting rod
It is closed the inner flow passage of rear enclosed valve body.
As the utility model preferred embodiment, the retainer plate and bearing integrated molding.
It is elastic connection as the utility model preferred embodiment, between the supporting rod and support base.
The wafer type hard seal butterfly valve of the utility model controls a valve plate rotation in valve body by rotatable shaft,
It is connected by bearing between valve plate and shaft, is conveniently adjusted the position in valve body of valve plate in this way.Also pass through support in valve body
Seat and supporting rod secure a valve plate, and two valve plates are formed to pressing from both sides closed structure, reduced during butterfly valve use in this way
The friction of valve plate and valve body, and then extend the service life of butterfly valve.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the dimensional structure diagram of the wafer type hard seal butterfly valve of the utility model.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
As shown in Figure 1, a kind of wafer type hard seal butterfly valve 1, including a valve body 10, a valve is rotationally equipped on valve body 10
The end of bar 40, valve rod 40 is equipped with a control handle 41, is equipped with a shaft 20 in valve body 10, passes through tooth between shaft 20 and valve rod 40
Tooth connects, and a bearing 21 is fixedly connected on the body of rod of shaft 20, a retainer plate 22, retainer plate 22 are rotationally equipped on bearing 21
On be fixedly connected with one first valve plate, be additionally provided with a support base 30 on valve body 10, a supporting rod be rotationally equipped on support base 30
31, one second valve plate is fixedly connected on supporting rod 31, the first valve plate and the second valve plate are closed the internal flow of rear enclosed valve body 10
Channel.
It is further improved as to the utility model, the retainer plate 22 and bearing 21 are integrally formed.
It is further improved as to the utility model, is elastic connection between the supporting rod 31 and support base 30.
The wafer type hard seal butterfly valve of the utility model controls a valve plate rotation in valve body by rotatable shaft,
It is connected by bearing between valve plate and shaft, is conveniently adjusted the position in valve body of valve plate in this way.Also pass through support in valve body
Seat and supporting rod secure a valve plate, and two valve plates are formed to pressing from both sides closed structure, reduced during butterfly valve use in this way
The friction of valve plate and valve body, and then extend the service life of butterfly valve.
The mentality of designing for only illustrating the utility model in one embodiment above, in the case where system allows,
The utility model can be extended to while external more function modules, to extend its function to greatest extent.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
