Description
Technical field
The present invention relates to a kind of valve, be specifically related to the butterfly valve of a kind of improved structure.
Background technology
Butterfly valve is again flap valve, is the regulation valve of a kind of simple in construction, can be used for the on-off control of low pressure pipeline medium
Butterfly valve refers to that closure member is disk, around valve shaft rotate reach open and close a kind of valve, valve can be used for control 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 is acted primarily as on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, around the axle of himself in valve body
Line rotates, thus reaches to open and close or the purpose of regulation.
Existing butterfly valve, generally includes valve body, valve rod and butterfly plate, and butterfly plate is arranged in the fluid passage in valve body, logical
That crosses butterfly plate and sealing ring coordinates the sealing realizing fluid passage.Due to butterfly valve life-time service, butterfly plate repeats opening and closing so that seal
Circle is deformed, and reduces the sealing of butterfly valve, affects its service life.
Summary of the invention
In order to solve the problems referred to above, the present invention provides the butterfly valve of a kind of improved structure, and this butterfly valve can be in sealing ring part
Deformation successor so has the highest sealing, and ruggedness is good, it is possible to effectively extends butterfly valve service life, reduces use cost.
The present invention is achieved through the following technical solutions:
The butterfly valve of a kind of improved structure, including valve body, valve rod and butterfly plate, described butterfly plate is arranged in the fluid passage of valve body, institute
Stating and be stained with one layer of cushion on the inwall of fluid passage, described cushion is made up of gum elastic, is internally provided with buffering cavity,
It is filled with spring in this cushion chamber body, described cushion is stained with one layer of elastic seal ring.
By spring being filled in cushion chamber body, it is possible to effectively prevent spring from contacting with the fluid of conveying, especially butterfly
After valve uses too long elastic seal ring to crack.Spring is protected by gum elastic, it is to avoid affected use by corrosion, extends butterfly
Valve service life.
Described elastic seal ring is made up of hydrogenated nitrile-butadiene rubber.
Being provided with top-down through hole in the middle part of described butterfly plate, described valve rod lower end is through through hole moving phase with body base
Even.
Described spring is volute spring, and volute spring is several and is uniformly distributed in cushion chamber body.Described Conical Projectile
Being fixed on cushion bottom spring on the side of valve body, 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.
The present invention compared with prior art, has such advantages as and beneficial effect:
The butterfly valve of a kind of improved structure of the present invention, by adhering to one layer of cushion between elastic seal ring and valve body, effectively promotes
The sealing effectiveness of butterfly valve, when butterfly valve uses the time longer, and after elastic seal ring deforms, the spring in cushion still may be used
So that elastic seal ring is close to the butterfly plate after closing, it is ensured that butterfly valve seal effect, extend butterfly valve service life.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, to this
Invention is described in further detail, and the exemplary embodiment of the present invention and explanation thereof are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment
As shown in Figure 1, 2, the butterfly valve of a kind of improved structure, including valve body 1, valve rod 2 and butterfly plate 3, described butterfly plate 3 is arranged at
In the fluid passage 4 of valve body 1, described fluid passage 4 inwall being stained with one layer of cushion 5, described cushion 5 is by gum elastic
Make, be internally provided with buffering cavity 51, be filled with spring 52 in this buffering cavity 51, described cushion 5 is stained with one layer
Elastic seal ring 6.
Described elastic seal ring 6 is made up of hydrogenated nitrile-butadiene rubber.
Being provided with top-down through hole in the middle part of described butterfly plate 3, lives through through hole and bottom valve body 1 in described valve rod 2 lower end
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 the present invention is applied in tubing, rotary valve rod 2, drive butterfly plate 3 rotate to fluid passage 4
Cross section is parallel, and now the spring 6 in cushion 5 is compressed to maximum, and butterfly plate 3 is in close contact with elastic seal ring 7 and is led to by fluid
Road 4 blocks completely, reaches sealing effectiveness, when butterfly valve use that the time is longer and after elastic seal ring 7 starts deformation, due to cushion
The existence of 5, spring 6 still can adjust self-deformation amount according to the deformation extent of elastic seal ring 7, makes up owing to elasticity is close
The space that seal 7 deforms and is likely to occur, it is ensured that butterfly plate 3 and elastic seal ring 7 remain able to seamless rank when butterfly plate 3 is closed
Connect, it is ensured that butterfly valve seal, extend butterfly valve service life.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect further
Describe in detail, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, all should comprise
Within protection scope of the present invention.
