Description
Technical field
The utility model is related to valve technology field, specially a kind of antiseep 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 that closure member (flap or butterfly plate) is 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.
Existing butterfly valve is in close contact by valve plate edge and valve seat realizes sealing when closed, and valve rod passes through in valve seat
Hole at prevent from leaking by rubber seal rings for seal, and some soft valve seats, when by unilateral pressure, valve plate is pressed
Power and with ovable valve stem squeezing valve seat and sealing ring so that valve seat and sealing ring deform upon, and valve rod is deviated to compression side, this
Situation lower valve rod and the squeeze side of valve seat and sealing ring are relatively also easy to produce gap, cause butterfly valve to leak, influence the sealing performance of valve,
Therefore we make this improvement, propose a kind of antiseep butterfly valve.
Invention content
To solve butterfly valve of the existing technology, valve plate stress is easy to happen the defect of leakage, the utility model when closed
A kind of antiseep butterfly valve is provided.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of antiseep butterfly valve of the utility model, including valve body, valve rod and valve plate, the inner wall of the valve body are fixed with valve
The interspersed connection in seat, the middle part of the top end of the valve body and the middle part of valve rod, the valve plate are set in the bottom of valve rod, and the valve plate is set
In the inside of valve seat, the side screw thread of the top end of the valve body is interspersed with stud, bottom end and the interspersed company of valve seat screw thread of the stud
It connects, the bottom end of the stud is fixedly connected with the top of fixed column, and the both sides of the valve interior wall are fixed with two pieces of phases respectively
One end of the limited block being mutually interspersed, two pieces of limited blocks is each passed through the two of the valve base inner wall inside for being placed on valve seat.
Further, the valve plate includes front and back, and one of limited block is in valve plate with fixed column
The back side.
Further, the top of the stud, which is fixed to set, is equipped with handle.
Further, the diameter of the fixed column cross section is less than the diameter of stud cross section.
Further, the outside of two pieces of limited blocks and the outside of fixed column are fixed with rubber layer.
Compared with prior art, the utility model has the advantages that：This kind of antiseep butterfly valve, by equipped with two
Block limited block can play the role of valve plate when being closed limit, while be equipped with by handle regulation stud bottom end
Fixed column, fixed column is ejected to the inside of valve seat, the position of valve plates is fixed by fixed column and two pieces of limited block coordinateds,
Valve rod and valve plate cause valve seat and sealing ring to deform upon to the offset of compression side when valve plate being prevented to be under pressure, avoid valve rod with
The squeeze side of valve seat and sealing ring generates gap, can then be leaked to avoid butterfly valve, improve the sealing performance of butterfly valve.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of antiseep butterfly valve, including valve body 1, valve rod 3 and valve plate 4, the inner wall of valve body 1 are fixed with
Valve seat 2, the middle part on 1 top of valve body are set in the bottom of valve rod 3 with the interspersed connection in the middle part of valve rod 3, valve plate 4, and valve plate 4 is placed in valve
The side screw thread of the inside of seat 2,1 top of valve body is interspersed with stud 5, bottom end and the interspersed connection of 2 screw thread of valve seat, the stud 5 of stud 5
Bottom end be fixedly connected with the top of fixed column 7, the both sides of 1 inner wall of valve body are fixed with the limit of two pieces of interlaced distributions respectively
Position block 8, one end of two pieces of limited blocks 8 is each passed through the two of 2 inner wall of the valve seat inside for being placed on valve seat 2.
Wherein, valve plate 4 includes front 10 and the back side 11, and one of limited block 8 is in the back of the body of valve plate 4 with fixed column 7
Face 11 prevents fixed column 7 from can not play the role of limit to valve plate 4, causes to generate gap hair between 4 stress of valve plate and valve seat 2
Raw leakage.
Wherein, the top of stud 5, which is fixed to set, is equipped with handle 6, and fixed column 7 is adjusted convenient for staff by handle 6
Position, avoid fixed column 7 hinder one's work personnel adjust valve plate 4.
Wherein, the diameter of 7 cross section of fixed column is less than the diameter of 5 cross section of stud, prevents fixed column 7 that can not be contracted to valve
The inside of seat 2 avoids the rotation for interfering valve plate 4.
Wherein, the outside of two pieces of limited blocks 8 and the outside of fixed column 7 are fixed with rubber layer 9, can by rubber layer 9
To reduce the friction between limited block 8 and fixed column 7 and valve plate 4, extend the service life of limited block 8 and fixed column 7.
It should be noted that the utility model is a kind of antiseep butterfly valve, when specific works, butterfly valve is mounted on pipeline
On, at this time by valve plate 4 just facing towards the upstream of pipeline, when the valve is closed, at this time by equipped with two pieces of limited blocks 8 can be with
Valve plate 4 when to being closed plays the role of limit, and then staff rotates stud 5 by handle 6, passes through stud
5 eject fixed column 7 from the inside of valve seat 2, are clamped to valve plate 4 by fixed column 7 and two pieces of 8 coordinateds of limited block,
Then the position that valve plate 4 can be fixed, valve rod 3 leads to valve seat with valve plate 4 to the offset of compression side when valve plate 4 being prevented to be under pressure
2 and sealing ring deform upon, avoid the squeeze side of valve rod 3 and valve seat 2 and sealing ring from generating gap, can then be sent out to avoid butterfly valve
Raw leakage, improves the sealing performance of butterfly valve, and when needing opened butterfly valve, staff first passes through handle 6 and rotates stud at this time
5, the position of fixed column 7 is adjusted by rotating stud 5, prevents fixed column 7 from interfering the rotation of valve plate 4.
