Abstract

The utility model relates to a self-cleaning ball valve which comprises a valve body, a ball arranged in the valve body, and a valve rod which penetrates the valve body and is connected with the ball. A rolling column matched with the valve rod is arranged on the ball, the valve body comprises an outlet and an inlet, and the ball is a tee joint ball. The self-cleaning ball valve has the advantages that compared with the prior art, the self-cleaning ball valve can carry out self-cleaning on a valve seat, the service lives of the ball and the valve seat are prolonged, and therefore the service life of the valve is prolonged, the valve rod is guaranteed not to break even though seal force is enlarged, and therefore the stability of the operation of the valve is guaranteed.

Description

A kind of Self-cleaning ball valve
Technical field
The utility model relates to the orbit ball valve technical field, is specifically related to a kind of Self-cleaning ball valve.
Background technique
Use at present the orbit ball valve on Coal Chemical Industry Heisui River, grey water condition, the general straight-through type sphere structure that adopts, in valve opening and the rotary course of closing, ball seal face and sealing surface of seat are without friction, when closing, two rollers on spheroid top coordinate with the wedge surface of 7 °～10 ° of stem lower portion, and spheroid relies on mechanical force to be locked at and realizes sealing on sealing surface of seat, stem lower portion and roller cooperation place are designed with eccentric structure, and stem diameter is little.In use there are many problems, as: 1, precipitate and stick to spheroid and valve base surface because the media such as solid coal dust, water coal slurry in actual conditions are easy to separate out, because valve seat and spheroid break away from switching process, so valve seat can't be realized to spheroid " scraping " self-cleaning function.Dirt accumulates over a long period, and not only affects the sealing effect of valve, the serious switch motion that also directly affects valve.2, because stem lower portion wedge surface and spheroid roller force-bearing situation when the limit position of valve closing action is harsh, add that between sealing pair, dirt can't be removed, when poorly sealed, artificially strengthen outside seal power valve rod is ruptured from wedge surface.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of Self-cleaning ball valve.
The technical solution of the utility model is: a kind of Self-cleaning ball valve, comprise valve body, be arranged on the spheroid in valve body, and pass the valve rod that valve body is connected with spheroid, spheroid top is provided with the roller that coordinates with valve rod, described valve body comprises an outflow opening and an inflow entrance, and described spheroid is the threeway spheroid.
Above-mentioned a kind of Self-cleaning ball valve, described spheroid comprise the fluid passage and and cleaning passage, the diameter of described cleaning passage is the 60%-90% of fluid passage diameter.
Above-mentioned a kind of Self-cleaning ball valve, the diameter of described cleaning passage are 80% of fluid passage diameters.
Above-mentioned a kind of Self-cleaning ball valve, described stem lower portion and roller cooperation place are structures without acceptance of persons.
Above-mentioned a kind of Self-cleaning ball valve, described valve rod adopts the manufacturing of precipitation hardening Steel material.
The beneficial effects of the utility model are: compared with prior art, the utility model can carry out automatically cleaning to spheroid and valve seat, has extended the life-span of spheroid and valve seat, therefore, has also extended the working life of valve; Even guarantee that valve rod strengthens sealing force and also can not rupture, thereby guarantee the stability of valve operation.
Description of drawings
Fig. 1 is the sectional view of structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model spheroid and valve rod joint.
In figure: 1, spheroid, 2, roller, 3, valve rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model as shown in Fig. 1-2, a kind of Self-cleaning ball valve, comprise: comprise valve body, be arranged on the spheroid 1 in valve body, and pass the valve rod 3 that valve body is connected with spheroid 1, spheroid 1 top is provided with the roller 2 that coordinates with valve rod 3, and described valve body comprises an outflow opening and an inflow entrance, and described spheroid 1 is the threeway spheroid.Above-mentioned a kind of Self-cleaning ball valve, described spheroid 1 comprise the fluid passage and and cleaning passage, the diameter of described cleaning passage is the 60%-90% of fluid passage diameter, preferred 80% is good.
spheroid 1 adopts the Three way type structural design, the threeway spheroid is connected with passage with the valve body lumen, spheroid 1 third channel diameter is 80% left and right of spheroid 1 fluid passage, like this in valve opening and the process of closing, because there is area difference in triple channel, therefore, medium forms eddy current at the valve lumen under the effect of hydrodynamic pressure, medium rinses sealing pair along 1360 ° of directions of spheroid simultaneously, namely reached the valve self-cleaning function, guarantee the sealing effect of valve and the stability of action, prevented that again the high-velocity fluid medium from directly washing away sealing surface of seat, cause the too early damage of sealing surface of seat, thereby extended valve working life.
Valve rod 3 bottoms and roller 2 cooperation places are structural design without acceptance of persons, make like this diameter nature overstriking 30% left and right of valve rod 3, and the material selection 17-4PH precipitation hardening steel of valve rod 3 replaces the 2Cr13 Martensitic Stain Less Steel, the mechanical propertys such as the tensile strength of 17-4PH precipitation hardening Steel material and yield strength are far above the 2Cr13 Martensitic Stain Less Steel, make valve rod 3 can fully satisfy harsh working condition requirement, also be not easy to make valve rod 3 from the wedge surface fracture even artificially strengthen sealing force, thereby guaranteed the long-term stability operation of valve.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
