Background technology
In recent years, with the rapid development of social economy, people’s lives level increasingly improves, and the field of butterfly valve is also more next
Wider, traditional metallic seal butterfly valve is caused by it seals auxiliary structure, in use for some time often due to the scuffing of sealing pair
Its sealing effect is destroyed, and then directly influences its service life.In addition, its used adjusting washer mostly be using rubber,
Asbestos material is made, and because its high temperature resistance is poor, also directly affects its service life under the high temperature conditions.Furthermore it is above-mentioned
Valve shaft in valve is combined with the mode for being all made of logical pin connection between valve plate, since its connecting pin bores is a through-hole, in reality
During the use of border often because pin, hole contact surface coincide it is bad due to there is the phenomenon that valve plate forward and backward mutual leakage.
Invention content
The present invention provides a kind of high leakproofness butterfly valve, overcomes above-mentioned shortcoming in the prior art and provides a kind of sealing
Structure is more scientific and reasonable, high temperature resistant, it is voltage resistance more preferably, and before can thoroughly preventing valve, after valve between mutual leakage phenomenon occurs
Sealed butterfly valve.
To achieve the goals above, the technical solution that the present invention takes is：A kind of high leakproofness butterfly valve, including valve body, hand
Handle, sealing mechanism, valve rod and butterfly plate, in valve inner centre position, radially installed has valve rod, described valve rod one end and valve body bottom
Portion contacts, and the top of other end stretching valve body and handle are coaxially connected, the valve rod radially installed and butterfly plate, outside the valve body
Edge is equipped with four groups of identical valve seats, and it is circumferentially distributed in outside and be secured to connect, be provided with ring on the inside of the valve body outer ring
Shape slot is equipped with sealing mechanism in the annular groove, and is closely connect with its cell wall, and the sealing mechanism includes deformable seal
Circle, inlet port and outlet port, the discharge port installation and right handle, and one end connection identical as deformable seal circle, and it is another
One end is fixedly connected with the valve body, the feed inlet installation and left handle, and one end is connected with deformable seal circle, and another
One end is fixedly connected with the valve body.
Preferably, the annular slot cross-section is " recessed " structure.
Preferably, the deformable seal circle is that the rubber with certain elasticity is constituted, and is internally provided with grease.
Preferably, the grease is to be constituted higher than the thickening agent of water density, base oil, additive three parts, wherein being thickened
Agent content is about 10%-20%, and base oil content is about 75%-90%, and the content of additive and filler is below 5%.
It is using the advantageous effect of above technical scheme：A kind of high leakproofness butterfly valve provides a kind of sealing structure more
It is scientific and reasonable, high temperature resistant, it is voltage resistance more preferably, and before can thoroughly preventing valve, after valve between the sealed butterfly valve of mutual leakage phenomenon occurs,
It matches to form gap with the sealing ring surface of valve plate globoidal structure in its sealing ring surface, deformable seal circle of the invention is located at it
In, and contain grease in deformable seal circle, and it is expanded in gap in this way so that valve plate and inner ring surface seamless connectivity, effectively
Ensure that integrity of the sealing pair in opening-closing process.

Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to the design of the present invention, technical solution
Solution, and contribute to its implementation.
As shown in Figs. 1-3, the present invention provides a kind of high leakproofness butterfly valve, overcome above-mentioned shortcoming in the prior art and
It is more scientific and reasonable to provide a kind of sealing structure, high temperature resistant, it is voltage resistance more preferably, and before can thoroughly preventing valve, after valve between phase occurs
The sealed butterfly valve of mutual leakage phenomenon.
Specifically, as shown in Figs. 1-3, including valve body 1, handle 2, sealing mechanism 3, valve rod 4 and butterfly plate 5, in valve body 1
Portion centre position radially installed has valve rod 4,4 one end of the valve rod to be contacted with 1 bottom of valve body, and the other end stretches out the top of valve body 1
Portion and handle 2 are coaxially connected, and 4 radially installed of the valve rod and butterfly plate 5,1 outer edge of the valve body are equipped with four groups of identical valve seats
6, and it is circumferentially distributed in outside and be secured to connect, be provided with annular groove 7 on the inside of 1 outer ring of the valve body, peace in the annular groove 7
It is closely connect equipped with sealing mechanism 3, and with its cell wall, the sealing mechanism 3 includes deformable seal circle 30, feed inlet 31 and goes out
Material mouth 32, the installation of the discharge port 32 and the right side of handle 2, and one end connection identical with deformable seal circle 30, and the other end and
Valve body 1 is fixedly connected, the installation of the feed inlet 31 and 2 left side of handle, and one end connection identical as deformable seal circle 30, and another
One end is fixedly connected with valve body 1.
7 section of the annular groove is " recessed " structure.
The deformable seal circle 30 is that the rubber with certain elasticity is constituted, and is internally provided with grease 33.
The grease 33 is to be constituted higher than the thickening agent of water density, base oil, additive three parts, wherein being thickened agent content
About 10%-20%, base oil content are about 75%-90%, and the content of additive and filler is below 5%.
Specific working mode is illustrated with specific embodiment below：
A kind of high leakproofness butterfly valve is provided with annular groove 7 on the inside of 1 outer ring of the valve body, is equipped in the annular groove 7
