Technical field
The utility model belongs to valve field, especially a kind of high-efficiency seal structure of sealed butterfly valve.
Background technology
The butterfly plate of butterfly valve is installed on the diametric(al) of pipeline.Butterfly valve structure is simple, small volume, in light weight, only by several
Individual part composition, and need to only be rotated by 90 ° can fast opening and closing, it is simple to operate, while the valve has good fluid control
Characteristic.When butterfly valve is in full open position, butterfly plate thickness is that medium flows through unique resistance during valve body, therefore passes through the valve
Caused pressure drop very little, therefore there are preferable metering characteristics.
Existing butterfly valve body typically uses the sealing means of valve body kiss-coating, and metal valve plate is by rotation in valve body
Lining is extruded, and is realized and is sealed, and the position of valve plate and valve body contact is integrated annulus of the system on valve body, and valve plate is direct with valve body
Sealed for linear sealing or face.
According to retrieval, the existing patent document disclosure similar with the application is as follows：
A kind of centre-pivoted butterfly valves for installing multimedium valve seat of CN205089990U, including valve body, valve rod, dish plate, multimedium valve
Seat and back-up ring, horizontal runner are formed with valve body, vertically-mounted in the middle part of valve body inner flow passage to have a valve rod, the valve in valve body
Bar bottom is provided with a dishful of plate, it is characterised in that：A multimedium valve seat coaxially is embedded with the runner of valve body, in multimedium valve seat
Outside is coaxially fixed with a back-up ring.
A kind of high intensity kiss-coating butterfly valves of CN203488733U, including valve body, valve seat, valve shaft and valve plate, valve seat are formed on valve body
Interior, valve plate is movably installed in valve seat by valve shaft, it is characterised in that：Symmetrically made downwards along outer wall on the outer wall of the valve body both sides
There is an arc reinforcement to be matched with outer wall profile, the valve seat outer surface is fixedly mounted with a rubber layer.
Utility model content
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided a kind of sealing structure is novel, pressure-resistant
The high-efficiency seal structure of the strong sealed butterfly valve of power.
The utility model adopts the following technical scheme that to solve technical problem：
A kind of high-efficiency seal structure of sealed butterfly valve, including valve body, valve rod and valve plate, valve rod is by being arranged on two on valve body
For the mounting hole radial seal hinge that side is symmetrically formed with the valve opening of valve body, valve plate is installed on valve body, valve plate by valve handle activity
Outer wrapping sealing rubber layer, the mounting hole outer rim that both sides are symmetrically formed with valve body are integrally formed with cambered surface sealing station, in sealing station
Edge connects with the rubber seal of the circular valve plate outer rim of valve plate, and a sealing ring is formed with the valve interior wall between two sealing station
Face, sealing ring surface inner surface are cambered surface, and when valve plate rotates, the both direction rotated along valve plate is formed respectively with the cambered surface of extension
Sealing surface, with being formed with radial ringed groove on the sealing surface of the valve plate of valve seal.
Moreover, sealing ring is set between valve rod and valve body.
Moreover, in the both sides joint face vulcanised rubber layer of valve body.
Good effect of the present utility model is as follows：
The application is formed with radial ringed groove on the sealing surface of valve plate and valve body, and this groove can be in valve seal
When produce a small deformation quantity, after deformation produce one bounce-back stress, the sealing greatly improved.
The sealing structure of butterfly valve provided by the utility model realizes the cambered surface sealing of sealing surface of valve plate, due to cambered surface sealing surface
For valve body, a boss is being formed with corresponding to sealing surface both sides on valve body, boss can rise to flowing through the liquid at this
To certain cushioning effect, reduce fluid to valve plate and the instant impact of valve body, reduce the abrasion of valve inner, extend valve body
Sealing life, ensure sealing effectiveness, process is actually detected, and seal pressure can reach 30-32kg.
The sealing structure of butterfly valve provided by the utility model seals for the cambered surface of valve plate, and cambered surface can reduce valve plate and rotate
Friction, reduce resistance when valve plate rotates, reduce the bearing capacity of valve rod, extend the usage time of valve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A to sectional view.
Fig. 3 is Fig. 2 B-B direction sectional view (valve plate closing).
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, and following examples are simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of sealing structure of butterfly valve, as Figure 1-3, including valve body 1, valve rod 6 and valve plate 4, valve rod is by being arranged on
For the mounting hole radial seal hinge that both sides are symmetrically formed with valve body in the valve opening of valve body, valve plate is installed on valve by valve handle activity
Body, by rotation valve rod, valve plate is driven to rotate, the opening and closing of the fluid passage of application valve body.
This is using new innovation：
1st, valve plate outer wrapping sealing rubber layer in the application, the form of practical first valve plate kiss-coating and valve body not kiss-coating.
2nd, the mounting hole outer rim that both sides are symmetrically formed with valve body is integrally formed with cambered surface sealing station 2, sealing station inner edge and valve
The rubber seal of the circular valve plate outer rim of plate connects, and a sealing ring surface 3 is formed with the valve interior wall between two sealing station, close
Seal ring face inner surface is cambered surface, and when valve plate rotates, the both direction rotated along valve plate is formed respectively with the cambered surface sealing of extension
Face.
3rd, with being formed with radial ringed groove 5 on the sealing surface of the valve plate of valve seal, this groove can be close in valve
A small deformation quantity is produced when envelope, the stress of a bounce-back, the sealing greatly improved are produced after deformation.
In order to increase sealing property, sealing ring is set in the application between valve rod and valve body.
, can be in the both sides joint face vulcanised rubber layer of valve body in order to increase the connection sealing of valve.
The sealing surface of the sealing structure of butterfly valve provided by the utility model is cambered surface, the sealing phase with existing valve body
Than sealing surface is wider, and when valve plate has minor rotation, valve plate is still in hermetically sealed state, and sealing effectiveness has been effectively ensured.
