When the soft seal ball valve is used, the valve seat and the ball body can be simultaneously rotated by a certain degree, the position of the medium washing sealing face cannot be repeated, the sealing effect of the valve is accordingly strengthened, the maintaining cost is reduced, the energy resource is saved, and the service life of the valve is prolonged.
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 technique
Since China reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " become the main flow of the current industrial development of China, and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).Soft sealing ball valve faucet body is spheroid, has manhole or passage by its axis, is mainly used to make the flow direction that cuts off, distributes and change medium in pipeline.When use, only need to just can close tightly by the operation of 90-degree rotation and very little moment of rotation.Existing soft sealing ball valve is in the moment of ball valve switch, and high-pressure medium washes away sealing surface towards two inlet/outlet crescent shape breach directions.And when each Open valve, medium is all flushed on the same position of sealing surface, after long-term use, valve is fragile, causes leakage, has increased again maintenance cost, having shortened the working life of valve, is the current ubiquitous critical defect of domestic and international all soft sealing ball valves.In order to address these problems, R&D institution and science and technology in enterprise personnel, in constantly research, exploration, utilize modern science and technology, although obtained technically some progress, still exist the technical barrier not yet overcoming in practice.
Summary of the invention
The object of the invention is to overcome above deficiency, a kind of soft sealing ball valve of resistance to erosion sealing surface is provided, the principle that while adopting valve open/close, spheroid and valve seat rotate simultaneously, in the time of each open and close valve, valve seat is convertible once certain angle also, and the position that therefore medium washes away valve seat will constantly change, both solved the technical barrier of valve leak, improved again working efficiency, reduced maintenance rate, the working life of valve is the corresponding several times that improved also.
The technical solution adopted for the present invention to solve the technical problems is: contain connecting body, valve seat, elastic cylindrical pin, spheroid, double-screw bolt, dunnage, valve body, Stuffing box, valve rod, DO bearing, valve seat is connected with connecting body, valve seat is provided with elastic cylindrical pin, connecting body is connected with valve body by double-screw bolt, on, lower supporting plate is connected with connecting body, spheroid is by DO bearing and upper, lower supporting plate is connected, on valve seat and spheroid, under the position of end in contact and valve seat and spheroid, the position of end in contact has certain numerical difference to spheroid perpendicular to the axis of passage, the lower end of valve rod is connected with spheroid, Stuffing box is connected with the upper end of valve rod.
The technology used in the present invention principle is: the valve seat of this valve and the axis of spheroid are provided with certain differential seat angle, and the ball valve angle difference of every kind of latus rectum, therefore on valve seat and spheroid, under the position of end in contact and valve seat and spheroid, the position of end in contact has certain numerical difference to spheroid perpendicular to the axis of passage.When valve rod drives spheroid while spending by clockwise direction rotation 90, valve seat is by the certain angle of spheroid driven rotary, therefore valve seat of the every open and close of valve will conversion certain angle once.In the time of valve opening, the distance of Δ L/2 π is moved in the position of valve seat and spheroid with respect to a front switch, the distance of Δ L/2 π has been moved in the position of washing away valve seat, so it is also different that medium washes away the position of valve seat of valve, thereby strengthen the sealing effect of sealing surface, improved the working life of valve.
The invention has the beneficial effects as follows: in use, valve seat and spheroid can rotate a certain angle this valve simultaneously, the position that therefore medium washes away sealing surface can not be repeated, thereby strengthen the sealing effect of valve, reduce maintenance cost, saved the energy, improved the working life of valve.
Brief description of the drawings
In conjunction with the accompanying drawings and embodiments the present invention to be further described below:
It in figure, is a kind of structural representation of soft sealing ball valve of resistance to erosion sealing surface.
In the drawings: 1. connecting body, 2. valve seat, 3. elastic cylindrical pin, 4. spheroid, 5. double-screw bolt, 6. dunnage, 7. valve body, 8. Stuffing box, 9. valve rod, 10.DO bearing.
Embodiment:
In the drawings: valve seat 2 is connected with connecting body 1, valve seat 2 is provided with elastic cylindrical pin 3, connecting body 1 is connected with valve body 7 by double-screw bolt 5, upper and lower dunnage 6 is connected with connecting body 1, spheroid 4 is connected with upper and lower dunnage 6 by DO bearing 10, on valve seat 2 and spheroid 4, the position of the position of end in contact and valve seat 2 and 4 times end in contact of spheroid has certain numerical difference to spheroid 2 perpendicular to the axis of passage, 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 this valve and the axis of spheroid 4 are provided with certain differential seat angle, and the ball valve angle difference of every kind of latus rectum, therefore on valve seat 2 and spheroid 4, the position of the position of end in contact and valve seat 2 and 4 times end in contact of spheroid has certain numerical difference to spheroid 4 perpendicular to the axis of passage.In the time that valve rod 9 drives spheroid 4 to spend by clockwise direction rotation 90, valve seat 2 is by the certain angle of spheroid 4 driven rotary, therefore valve seat 2 of the every open and close of valve will conversion certain angle once.In the time of valve opening, the distance of Δ L/2 π is moved in the position of valve seat 2 and spheroid 4 with respect to a front switch, the distance of Δ L/2 π has been moved in the position of washing away valve seat 2, so it is also different that medium washes away the position of valve seat 2 of valve, thereby strengthen the sealing effect of sealing surface, improved the working life of valve.
