Description
Technical field
This utility model relates to field of fluid control, is specifically related to a kind of eccentric-butterfly-valve.
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 (flap or butterfly plate) is disk, rotates a kind of valve reaching to open and close around valve shaft, and valve can
For controlling all kinds such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium
The flowing of fluid.Pipeline acts primarily as cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Axis around himself rotates, thus reaches to open and close or the purpose of regulation.
Utility model content
The purpose of this utility model is to provide the eccentric-butterfly-valve of a kind of favorable sealing property.
To achieve these goals, the technical solution adopted in the utility model is: a kind of eccentric-butterfly-valve, including valve body and valve
Bar, valve body is provided with valve seat, and valve rod is provided with the butterfly plate assembly coordinated with valve base sealing, it is characterised in that: described butterfly plate assembly
Including butterfly plate, sealing ring, butterfly plate trim ring, described dish plate trim ring is pressed on O-ring seal on dish plate, outside sealing ring radial direction
Side is formed to seal with the sealing surface of valve seat and coordinates；Described sealing ring is made up of rubber magnet material, makes the sealing ring can be close with valve seat
Front cover is attracting.
This utility model is further arranged to, and butterfly plate arranges the boss adaptive with sealing ring inner chamber, in sealing ring footpath
Being provided with elastic ring between sealing ring and boss on direction, described elastic ring is arranged for disconnecting, and the cross section of elastic ring is semicircle
Annular and opening are arranged towards boss.
This utility model is further arranged to, and described butterfly plate trim ring is elastic compression sealing ring.
This utility model is further arranged to, and described butterfly plate is provided with screwed hole, and butterfly plate trim ring is provided with and screwed hole
Corresponding through hole, screw is connected to described screwed hole through through hole, is provided with compression spring between nut and the butterfly plate trim ring of screw.
This utility model is further arranged to, and described elastic ring is made up of plastic material.
The beneficial effects of the utility model: eccentric-butterfly-valve provided by the utility model, sealing ring has rubber magnet material system
Become, make to exist between sealing ring and valve seat magnetic attraction, and sealing ring forms sealing diametrically and coordinates, by sealing with valve seat
Between circle and boss, elastic ring is set, makes sealing ring diametrically by elastic force, certain elastic deformation can occur, to be formed
Elastic packing.Magnetic attraction cooperation elastic packing can reach good sealing effectiveness.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Below with reference to Fig. 1 to Fig. 3, this utility model is illustrated.
A kind of eccentric-butterfly-valve, including valve body 1 and valve rod 2, valve body 1 is provided with valve seat 3, and valve rod 2 is provided with and seals with valve seat 3
The butterfly plate assembly coordinated, described butterfly plate assembly includes the butterfly plate 4 of circle, the sealing ring 5 of annular, butterfly plate trim ring 6, described dish plate
6 sealing rings 5 of trim ring are pressed on dish plate 4, and the sealing surface of the lateral surface of sealing ring 5 radial direction and valve seat 3 forms sealing and joins
Close；Described sealing ring 5 is made up of rubber magnet material, and sealing ring 5 has magnetic attraction, makes the sealing ring 5 can be with the sealing surface phase of valve seat 3
Inhaling, sealing effectiveness is more preferable.
Arranging the boss 7 adaptive with sealing ring 5 inner chamber on butterfly plate 4, sealing ring 5 is enclosed within boss 7, at sealing ring 5 radially
Being provided with elastic ring 8 between sealing ring 5 and boss 7 on direction, described elastic ring 8 is arranged for disconnecting, and the cross section of elastic ring 8 is half
Annular and opening are arranged towards boss 7.This arranges Elastic ring 8 and is pressed between sealing ring 5 and boss 7, forces sealing
The deformation that circle 5 expands outwardly, the elastic ring 8 of semi-circular shape is squeezed and certain elastic deformation also can occur simultaneously, this
Sample is just so that sealing ring 5 exists certain deformation space diametrically, and sealing ring 5 and valve seat 3 form elastic packing.
Good sealing effectiveness can be reached above by magnetic attraction cooperation elastic packing.
Elastic ring is made up of 8 plastic materials, will not be attracting with sealing ring 5.
Butterfly plate trim ring 6 is elastic compression sealing ring 5.Described butterfly plate 4 is provided with screwed hole, and butterfly plate trim ring 6 is provided with and spiral shell
The through hole that pitpair is answered, screw 9 is connected to described screwed hole through through hole, is provided with pressure between nut and the butterfly plate trim ring 6 of screw
Contracting spring 10.This is set to be avoided 6 sealing rings 5 of butterfly plate trim ring to be completely fixed, and has obstructed the elastic deformation of sealing ring 5.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, above-mentioned vacation
If these improve and modification also should be regarded as protection domain of the present utility model.
