Description
Technical field
The utility model relates to a kind of high frequencies to control butterfly valve.
Background technique
Butterfly valve is a kind of relatively simple regulating valve of structure, is generally intended for use primarily in water in pipeline, various corrosive medias, mud
The cutting or throttling action of the various types fluid such as slurry, oil product, liquid metal, also just because of mainly for various types of streams
Body, therefore, sealing performance are even more important, existing butterfly valve seal poor performance, are easy to lead because of decentraction when frequently switching on
Torque is caused abnormal conditions occur.
Summary of the invention
In order to solve the above-mentioned technical problem, it is simple to provide a kind of structure for the utility model, easy to operate, quick, using can
A kind of high frequency control butterfly valve leaned on.
The utility model is achieved through the following technical solutions:
A kind of high frequency control butterfly valve, including valve body, upper valve rod, lower valve rod, valve seat and butterfly plate, upper valve rod one end and pneumatic driving
Moving part connection, the other end successively penetrate upper with butterfly plate in the upper metal axle sleeve being set in valve seat, soft axle sleeve from top to bottom
End connection, upper metal axle sleeve bottom are set to the upper end of soft axle sleeve, and upper metal axle sleeve top is fixed by circlip, lower valve rod one
End, which penetrates, to be set in the intracorporal lower metal axle sleeve of valve, the lower end connection of the other end and butterfly plate.
Further, sealing ring is provided between the upper valve rod bottom and the valve seat.
Further, there are two the sealing ring settings.
Further, sealing block made of resin material is provided between the lower valve rod and the valve seat.
Further, the butterfly plate is spherical plate.
Further, the butterfly plate upper and lower side is respectively arranged with upper plane parallel to each other, lower plane.
Further, it is connected between the upper valve rod and the butterfly plate by square head.
The utility model the utility model has the advantages that the utility model is provided with metal axle sleeve, soft axle sleeve and lower metal axle sleeve,
Ensure that upper and lower axle is concentric under the position-limiting action of upper and lower metal axle sleeve, torque will not be caused to occur because of decentraction when frequently switching on
Abnormal conditions.

Specific embodiment
As shown in Figures 1 to 6, a kind of high frequency controls butterfly valve, including valve body 1, upper valve rod 2, lower valve rod 3, valve seat 4 and butterfly plate 5,
2 one end of upper valve rod is connect with pneumatic driving moving part, the other end successively penetrate from top to bottom the upper metal axle sleeve 6 being set in valve seat 4,
It is connect in soft axle sleeve 7 with the upper end of butterfly plate 5, upper 6 bottom of metal axle sleeve compresses the upper end of soft axle sleeve 7, on upper metal axle sleeve 6
Portion is fixed by circlip 8, and 3 one end of lower valve rod penetrates in the lower metal axle sleeve 9 being set in valve body 1, under the other end and butterfly plate 5
End connection.Ensure that upper 3 axis of lower valve rod is concentric under the position-limiting action of upper and lower metal axle sleeve 9, it will not be because of difference when frequently switching on
The heart and lead to torque abnormal conditions.
In the present embodiment, there are two O-ring seals 10 for setting between 2 bottom of upper valve rod and valve seat 4.Butterfly plate 5 is spherical plate.
5 upper and lower side of butterfly plate is respectively arranged with upper plane 51 parallel to each other, lower plane 52.The upper plane 51 and lower plane 52 of butterfly plate 5 exist
After valve assembles, there is decrement to valve seat 4, realize initial sealing, so that the medium in valve internal does not appear in
In cavity between the type of upper valve rod 2 and 0 sealing ring 10, even if there is a small amount of medium to occur in this cavity, O-ring seal 10 also can
Play the role of sealing, it is ensured that medium is not exposed.
In the present embodiment, connected between upper valve rod 2 and butterfly plate 5 by square head.This is provided for ensuring that connection is more steady
Gu.
In the present embodiment, the position contacted in valve seat 4 with upper valve rod 2, lower valve rod 3 is formed from a resin, to enhance valve seat 4
Intensity.
Technical solution provided by utility model embodiment is described in detail above, it is used herein specifically a
Example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Understand the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitation to utility model.
