Description

Ball valve with dustproof function

Technical Field

The utility model relates to the technical field of ball valves, in particular to a ball valve with a dustproof function.

Background

The ball valve can be applied to industries such as petroleum, natural gas, chemical industry, metallurgy, medicine, electric power and the like, and is a valve in which a ball body is driven by a valve rod and rotates around the axis of the ball valve. The device can also be used for regulating and controlling fluid, wherein the hard seal V-shaped ball valve has strong shearing force between the V-shaped ball core and the metal valve seat of the hard alloy for surfacing, and is particularly suitable for mediums containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the flow direction switching of the medium on the pipeline, and simultaneously can close any channel to connect the other two channels.

Some ball valves are used on devices containing a large amount of dust in mediums such as polysilicon, coal chemical industry and the like, and the ball valves in dust environment can have particle mediums entering into cavities on valve seats for containing elastic elements, so that the movable space of the elastic elements can be blocked, the compression space of the elastic elements is influenced, the service life of the elastic elements is influenced, and finally the service life of the whole valve is influenced.

To this end, we propose a ball valve with dust-proof function to solve the above problems.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-2, a ball valve with dustproof function, including valve body 1, set up spheroid 2 in valve body 1 and set up two disk seat 3 in valve body 1, two disk seat 3 slip respectively cup joint on the both sides lateral wall of spheroid 2, be provided with two annular in valve body 1 and hold the chamber, two annular hold the chamber and be located the both sides of spheroid 2 respectively, disk seat 3 is located annular and holds the intracavity, annular holds the intracavity and has set gradually disk seat clamping ring 4, disk seat sealing washer 5 and disk spring 6, disk seat clamping ring 4 and disk seat sealing washer 5 cup joint in proper order on the lateral wall of disk seat 3, the inside wall in annular holds the chamber offsets with disk seat clamping ring 4 through disk spring 6, the effect of disk seat clamping ring 4 and disk seat sealing washer 5 is the tight fit degree between improvement disk seat 3 and the valve body 1, avoid particulate medium to enter into the cavity that holds disk spring 6.

In the utility model, more specifically, one side of the valve seat pressing ring 4, which is close to the disc spring 6, is provided with an annular groove, one end, which is far away from the annular containing cavity, of the disc spring 6 is propped against the inner bottom of the annular groove, and the annular groove has the function of improving the stability of the disc spring 6 on the pressing of the valve seat pressing ring 4.

In the utility model, more specifically, the cross section of the valve seat sealing ring 5 is a right triangle, and the valve seat 3 is provided with an inclined slope corresponding to the valve seat sealing ring 5.

In the utility model, more specifically, the cross section of the annular containing cavity on the valve body 1 is L-shaped, so the design is designed, and the purpose is to ensure that the valve body 1 is tightly matched with the valve seat 3, prevent a granular medium from entering into the cavity containing the disc spring 6, prevent the elastic space of the disc spring 6 from being influenced, and avoid the service life of the ball valve from being influenced.

According to the ball valve, the valve seat pressing ring 4 and the valve seat sealing ring 5 are sleeved on the outer side wall of the valve seat 3, so that the tight fit degree between the valve seat 3 and the valve body 1 can be improved, the problem that granular media cannot enter into a cavity for accommodating the disc spring 6 and cannot influence the elastic space of the disc spring 6 is solved, and the technical problems that the existing ball valve is used in a dust environment, the granular media enter into the cavity for accommodating the disc spring 6 on the valve seat 3, the movable space of the disc spring 6 is influenced, and the service life of the ball valve is finally influenced are solved.
