Abstract
The utility model discloses a wide butterfly valve of application scope, including valve body, valve rod and butterfly plate, the butterfly plate sets up in the fluid passage of valve body, be stained with the one deck buffer layer on the fluid passage inner wall, the buffer layer is become by elasticity rubber, its inside buffering cavity that is equipped with, and the internal packing of this cushion chamber has a spring, be stained with one deck elasticity sealing washer on the buffer layer. This butterfly valve can warp successor's so in the sealing washer part and have very high leakproofness, and the durability is good, can effectively prolong butterfly valve life, reduces use cost.
Description
Technical field
This utility model is related to a kind of valve and in particular to a kind of butterfly valve applied widely.
Background technology
Butterfly valve is flap valve again, is a kind of simple regulating valve of structure, can be used for the on-off control of low pressure pipeline medium
Butterfly valve refers to that closure member is disk, rotates reaching a kind of valve of open and close around valve shaft, valve can be used for controlling air,
The flowing of all kinds fluids such as water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium,
Cut-out and throttling action are acted primarily as on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, around the axle of its own in valve body
Line rotates, thus reaching the purpose opening and closing or adjusting.
Existing butterfly valve, generally includes valve body, valve rod and butterfly plate, and butterfly plate is arranged in the fluid passage in valve body, leads to
The sealing of fluid passage is realized in the cooperation crossing butterfly plate and sealing ring.Due to butterfly valve life-time service, butterfly plate repeats opening and closing so that sealing
Circle is deformed, and reduces the sealing of butterfly valve, affects its service life.
Content of the invention
In order to solve the above problems, this utility model provides a kind of butterfly valve applied widely, and this butterfly valve can be in sealing
Circle part deforms successor and so has very high sealing, and ruggedness is good, can effectively extend butterfly valve service life it is adaptable to difference
The conveying of type of fluid medium.
This utility model is achieved through the following technical solutions：
A kind of butterfly valve applied widely, including valve body, valve rod and butterfly plate, described butterfly plate is arranged at the fluid passage of valve body
Interior, described fluid passage inwall is stained with one layer of cushion, described cushion is made up of gum elastic, is internally provided with buffering
Cavity, is filled with spring in this cushion chamber body, and described cushion is stained with one layer of elastic seal ring.
By being filled in spring in cushion chamber body, can effectively prevent spring and the fluid of conveying from contacting, especially in butterfly
After valve is using too elastic seal ring cracks long.Spring is protected by gum elastic, it is to avoid is affected by corrosion to use, extends butterfly
Valve service life.
Described elastic seal ring is made up of hydrogenated nitrile-butadiene rubber.
It is provided with top-down through hole, described valve rod lower end is through through hole and moving phase with body base in the middle part of described butterfly plate
Even.
Described spring is volute spring, and volute spring is several and is uniformly distributed in cushion chamber body.Described Conical Projectile
Spring bottom is fixed on cushion on the side of valve body, and described volute spring top is fixed on cushion near elastic seal ring
Side on.
Volute spring has higher stability, it is to avoid during life-time service, spring is distorted deformation, prolongs further
Long butterfly valve service life.
This utility model compared with prior art, has such advantages as and beneficial effect：
A kind of butterfly valve applied widely of this utility model, by one layer of buffering of adhesion between elastic seal ring and valve body
Layer, effectively improves the sealing effectiveness of butterfly valve, when butterfly valve use time is longer, after elastic seal ring deforms, in cushion
Spring elastic seal ring still can be made to be close to close after butterfly plate it is ensured that butterfly valve seal effect, extend butterfly valve service life,
And the conveying of different in flow rate fluid media (medium) can be applied to.

Specific embodiment
For making the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiment and accompanying drawing,
The utility model is described in further detail, and exemplary embodiment of the present utility model and its explanation are only used for explaining this
Utility model, is not intended as to restriction of the present utility model.
Embodiment
As shown in Figure 1, 2, a kind of butterfly valve applied widely, including valve body 1, valve rod 2 and butterfly plate 3, described butterfly plate 3 is arranged
In the fluid passage 4 of valve body 1, described fluid passage 4 inwall is stained with one layer of cushion 5, described cushion 5 is by elastic rubber
Glue is made, and is internally provided with buffering cavity 51, is filled with spring 52, described cushion 5 is stained with one in this buffering cavity 51
Layer elastic seal ring 6.
Described elastic seal ring 6 is made up of hydrogenated nitrile-butadiene rubber.
It is provided with top-down through hole, described valve rod 2 lower end is passed through through hole and lived with valve body 1 bottom in the middle part of described butterfly plate 3
Dynamic connected.
Described spring 52 is volute spring, and volute spring is several and is uniformly distributed in buffering cavity 51.Described cone
Shape spring bottom is fixed on cushion 5 on the side of valve body 1, and described volute spring top is fixed on cushion 5 near bullet
On the side of property sealing ring 6.
Butterfly valve in this utility model is applied in tubing, rotary valve rod 2, drive butterfly plate 3 rotate to fluid
Passage 4 section is parallel, and now the spring 6 in cushion 5 is compressed to maximum, and butterfly plate 3 is in close contact and will flow with elastic seal ring 7
Body passage 4 blocks completely, reaches sealing effectiveness, when butterfly valve use time is longer elastic seal ring 7 starts deformation after, due to slow
Rush the presence of layer 5, spring 6 still can adjust self-deformation amount according to the deformation extent of elastic seal ring 7, makes up due to bullet
Space that property sealing ring 7 deforms and is likely to occur it is ensured that when butterfly plate 3 is closed butterfly plate 3 and elastic seal ring 7 remain able to seamless
Linking, it is ensured that butterfly valve seal, extends butterfly valve service life.
Above-described specific embodiment, is entered to the purpose of this utility model, technical scheme and beneficial effect
One step describes in detail, be should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
Fixed protection domain of the present utility model, all any modifications within spirit of the present utility model and principle, made, equivalent replaces
Change, improve, should be included within protection domain of the present utility model.
