Description
Technical field
The present invention relates to a kind of soft sealing ball valve, particularly a kind of soft sealing ball valve of resistance to erosion sealing surface.
Background technology
Since China reforms and opens up to the outside world, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " turns into China's mesh
The main flow of preceding industrial development, China's industry progressively develop to intensive style, energy-saving and emission-reduction, the direction of low-carbon.Soft sealing ball valve cock
Body is spheroid, has manhole or passage by its axis, is mainly used to make the stream for cutting off, distributing and changing medium in pipeline
Dynamic direction.Only need just be closed tightly with the operation being rotated by 90 ° and the rotating torque of very little during use.Existing soft seal
Ball valve washes away sealing surface in the moment of ball valve switch, high-pressure medium towards two import and export crescent moon v notch v directions.And every time
During Open valve, medium is all flushed on the same position of sealing surface, and after long-term use of, valve is fragile, causes to leak, and is increased again
Maintenance cost is added, has shortened the service life of valve, be that the fatal of all soft sealing ball valve generally existings lacks both at home and abroad at present
Fall into.In order to solve these problems, R＆D institution and science and technology in enterprise personnel in continuous research, explore, using modern science and technology,
Although technically achieving some progress, the technical barrier not yet overcome is remained in practice.
The content of the invention
It is an object of the invention to overcome the above insufficient, there is provided a kind of soft sealing ball valve of resistance to erosion sealing surface, using valve
The principle that spheroid and valve seat rotate simultaneously during door open and close, in each open and close valve, valve seat also convertible once certain angle
Degree, therefore medium washes away the position of valve seat and will constantly changed, and has both solved the technical barrier of valve leak, improves work effect again
Rate, reduces maintenance rate, and the service life of valve also accordingly improves several times.
The technical solution adopted for the present invention to solve the technical problems is：Contain connector, valve seat, elastic cylindrical pin, ball
Body, stud, supporting plate, valve body, stuffing box, valve rod, DO bearings, valve seat are connected with connector, and valve seat is provided with elastic cylinder
Pin, connector is connected by stud with valve body, and upper and lower supporting plate is connected with connector, spheroid by DO bearings with it is upper and lower
Supporting plate is connected, and the position of valve seat and spheroid upper-end contact is with the position of end in contact under valve seat and spheroid to spheroid perpendicular to logical
The axis in road has certain numerical difference, and the lower end of valve rod is connected with spheroid, and stuffing box is connected with the upper end of valve rod.
The technology used in the present invention principle is：The valve seat of the valve and the axis of spheroid are provided with certain differential seat angle, and
The ball valve angle of every kind of latus rectum is different, therefore the position of valve seat and spheroid upper-end contact and the position of end in contact under valve seat and spheroid
There is certain numerical difference perpendicular to the axis of passage to spheroid.When valve rod drives spheroid to be rotated by 90 ° by clockwise direction,
Valve seat will be driven by spheroid and rotate a certain angle, therefore valve will convert once certain angle per valve seat of open and close.When
During valve opening, the position of valve seat and spheroid moves Δ L/2 π distance relative to preceding once switch, that is, washes away the position of valve seat
Δ L/2 π distance is moved, so the position that medium washes away the valve seat of valve is also different, so as to enhance the close of sealing surface
Effect is sealed, improves the service life of valve.
The beneficial effects of the invention are as follows：When in use, valve seat and spheroid can rotate a certain angle the valve simultaneously, because
The position that this medium washes away sealing surface will not repeat, and so as to enhance the sealing effectiveness of valve, reduce maintenance cost, save
The energy, improve the service life of valve.
Brief description of the drawings
Here is that the present invention is further described in conjunction with the accompanying drawings and embodiments：
It is a kind of structural representation of the soft sealing ball valve of resistance to erosion sealing surface in figure.
In figure：1. connector, 2. valve seats, 3. elastic cylindrical pins, 4. spheroids, 5. studs, 6. supporting plates, 7. valve bodies, 8.
Stuffing box, 9. valve rods, 10.DO bearings.
Embodiment：
In figure：Valve seat 2 is connected with connector 1, and valve seat 2 is provided with elastic cylindrical pin 3, connector 1 by stud 5 with
Valve body 7 is connected, and upper and lower supporting plate 6 is connected with connector 1, and spheroid 4 is connected by DO bearings 10 with upper and lower supporting plate 6
Connect, the position of valve seat 2 and the upper-end contact of spheroid 4 is with the position of 4 times end in contact of valve seat 2 and spheroid to spheroid 2 perpendicular to passage
Axis has certain numerical difference, and the lower end of valve rod 9 is connected with spheroid 4, and stuffing box 8 is connected with the upper end of valve rod 9.
The valve seat 2 of the valve and the axis of spheroid 4 are provided with certain differential seat angle, and the ball valve angle of every kind of latus rectum is different,
Therefore valve seat 2 and the position of the upper-end contact of spheroid 4 and the position of 4 times end in contact of valve seat 2 and spheroid to spheroid 4 perpendicular to passage
Axis has certain numerical difference.When valve rod 9 drives spheroid 4 to be rotated by 90 ° by clockwise direction, valve seat 2 will be by the band of spheroid 4
It is dynamic to rotate a certain angle, therefore valve will convert once certain angle per valve seat 2 of open and close.When valve opening, valve
Relative to the preceding distance for once switching mobile Δ L/2 π, that is, the position for washing away valve seat 2 moves Δ L/2 for the position of seat 2 and spheroid 4
π distance, so the position that medium washes away the valve seat 2 of valve is also different, so as to enhance the sealing effectiveness of sealing surface, improve
The service life of valve.
