Description
Technical field
The utility model relates to a kind of valve more particularly to a kind of deformation spherical surface eccentric valves.
Background technique
Ball valve and butterfly valve be in current valve using at most, using two kinds of most wide valves, the two is simple to operation, to pipe
Track media plays the role of cut-off and cutting.Ball valve (ball valve), opening and closing element (sphere) are driven by valve rod, and around ball valve axis
The valve that line rotates.Also it can be used for the adjusting and control of fluid, wherein sealing its V-type core of V-type ball valve and built-up welding firmly
There is very strong shearing force, the medium especially suitable for fibre-bearing, small solid pellet etc. between the metal seat valve of hard alloy.
And multi-pass ball valve not only can flexibly control the interflow of medium, the switching for shunting and flowing on pipeline, while can also close any
Channel and make other two channel be connected.This class valve should be generally horizontally mounted in the duct.Ball valve is according to driving method point
Are as follows: pneumatic ball valve, electrical ball valve, manual ball valve.Butterfly valve is also known as flap valve, is a kind of simple regulating valve of structure, mainly by valve
Body, valve rod, butterfly plate and sealing ring composition.Valve body is cylindrical, and axial length is short, built-in butterfly plate.Existing butterfly plate or ball valve are deposited
In serious wear, receiving pressure is big, poor sealing performance, and opening and closing torque is big, and service life is short.
Utility model content
In view of the foregoing drawbacks, the purpose of this utility model is to provide a kind of structure is simple, reduce opening and closing torque, leakproofness
It can a kind of good, deformation spherical surface eccentric valve with long service life.
Thus the technical scheme adopted by the utility model is
Including valve body, valve rod and opening and closing element, the opening and closing element is located in valve body, and valve rod is connect with opening and closing element, the opening and closing
Part side is equipped with ring-shaped step, is equipped with sealing ring on the ring-shaped step, the sealing ring is fixed on opening and closing element by pressure ring
On, valve seat is equipped in valve body, valve seat and sealing ring are closed to form sealing surface, which is characterized in that the sealing surface is curved surface, sealing
The radial section in face is positive circular section, and the oblique line and valve flowing channel center line that the center of circle of positive circular section is formed form angle a, oblique line
Vertical with valve rod axial line with the valve flowing channel center line plane formed, valve rod axial line is set with valve flowing channel center line bias
Set, the center of circle of a radial section in all radial sections of sealing surface far from valve rod also on valve flowing channel center line, when
When oblique line is overlapped with valve flowing channel center line, sealing surface is spherical surface, and sealing ring is a part of sphere, and the centre of sphere of sphere is in valve
On runner center line.
As a further improvement of the above technical scheme, the opening and closing element is butterfly plate.
As a further improvement of the above technical scheme, the opening and closing element is sphere.
The utility model has the advantages that:
The utility model structure is simple, by using the utility model structure, solves sealing surface each point and is pressurized unevenly
Property problem, realize high temperature low temperature because deforming leakage problem caused by sealing surface unbalance stress, can be realized reduction opening and closing torque, it is close
Sealing property is good, extends valve service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 it is valve body in figure, 2 be valve rod, 3 be opening and closing element, 4 be sealing ring, 5 be pressure ring, 6 be valve seat, 7 be sealing surface, 8 is
Oblique line, 9 be valve flowing channel center line, 10 be valve rod axial line, 11 be the centre of sphere.
Specific embodiment
A kind of deformation spherical surface eccentric valve, including valve body 1, valve rod 2 and opening and closing element 3, the opening and closing element 3 are located in valve body 1,
Valve rod 2 is connect with opening and closing element 3, and 3 side of opening and closing element is equipped with ring-shaped step, is equipped with sealing ring 4, institute on the ring-shaped step
It states sealing ring 4 to be fixed on opening and closing element 3 by pressure ring 5, valve seat 6 is equipped in valve body 1, valve seat 6 and the closure of sealing ring 4 form sealing
Face 7, the sealing surface 7 are curved surface, and the radial section of sealing surface 7 is positive circular section, the oblique line 8 that the center of circle of positive circular section is formed with
Valve flowing channel center line 9 forms angle a, and oblique line 8 and the plane formed of valve flowing channel center line 9 are vertical with valve rod axial line 10,
Valve rod axial line 10 and 9 eccentric setting of valve flowing channel center line, one in all radial sections of sealing surface 7 far from valve rod 2
The center of circle of radial section is also on valve flowing channel center line 9, and when oblique line 8 is overlapped with valve flowing channel center line 9, sealing surface 7 is
Spherical surface, sealing ring 4 are a part of sphere, and the centre of sphere 11 of sphere is on valve flowing channel center line 9.
As a further improvement of the above technical scheme, the opening and closing element is butterfly plate.
As a further improvement of the above technical scheme, the opening and closing element is sphere.
In all radial sections of the sealing surface of sealing ring, wherein the center of circle of the radial section far from valve rod, that is, it is close
The center of circle of the sealing surface leftmost side end face of seal ring is on valve flowing channel center line.
It is emphasized that: the above description is only the embodiments of the present invention, is not intended to limit the utility model
The scope of the patents, equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, or it is straight
It connects or is used in other related technical areas indirectly, be also included in the patent protection scope of the utility model.
