Description

Automatic regulating valve disk seat structure

Technical Field

The utility model relates to a valve especially relates to an automatic regulating valve disk seat structure.

Background

A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved.

Ball valve, the open-close piece (ball) is driven by the valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline.

No matter butterfly valve or ball valve all include valve body, disk seat and rings, and current disk seat fixed mounting is inside the valve body, and in the long-time use, the disk seat can take place wearing and tearing, disk seat and opening and closing member contact failure, greatly reduced sealed effect, and need dismantle when current disk seat is adjusted, adjust and get up the trouble.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect, the utility model aims to provide a can automatic regulating valve disk seat position to guarantee the automatic regulating valve disk seat structure of valve seal effect.

Therefore, the utility model adopts the technical proposal that:

including valve body, disk seat and rings, the disk seat is installed inside the feed liquor end of valve body, the inside annular ka tai that is equipped with of feed liquor end of valve body, the card is in annular ka tai department in disk seat inner, the feed liquor end inner wall of valve body is equipped with the annular groove, rings are placed in the annular groove, rings are located the outside of disk seat, be equipped with the dish spring between rings and the disk seat, the hole diameter of dish spring is greater than the hole diameter of rings, the front side terminal surface of disk seat is equipped with annular boss, the dish spring cover is established on annular boss.

As a further improvement of the technical scheme, an adjusting gap is arranged between the front end face of the annular boss and the hanging ring.

As a further improvement of the technical scheme, the outer edge of the disc spring is abutted against the inner end of the hanging ring.

As a further improvement of the technical scheme, a plurality of threaded holes located on the same circumference are formed in the end face of the hanging ring, adjusting bolts are arranged in the threaded holes, and the end portions of the adjusting bolts abut against the outer edge of the disc spring.

As a further improvement of the technical scheme, an annular sealing groove is formed in the outer circumferential surface of the valve seat, and a sealing ring is placed in the annular sealing groove.

The utility model has the advantages that:

the utility model discloses simple structure, through adopting the utility model discloses the structure is add the dish spring between rings and disk seat, can the automatically regulated disk seat position, through the rotation regulation bolt, can further increase the elasticity of dish spring, further strengthens the sealed effect of valve.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a partially enlarged view of a in fig. 1.

In the figure, 1 is a valve body, 2 is a valve seat, 3 is a lifting ring, 4 is an annular clamping table, 5 is a disc spring, 6 is an annular boss, 7 is an adjusting bolt, and 8 is a sealing ring.

Detailed Description

The utility model provides an automatic adjusting valve disk seat structure, includes valve body 1, disk seat 2 and rings 3, disk seat 2 is installed inside the feed liquor end of valve body 1, the inside annular ka tai 4 that is equipped with of feed liquor end of valve body 1, 2 inner cards of disk seat are in annular ka tai department, the feed liquor end inner wall of valve body 1 is equipped with the annular groove, rings 3 place in the annular groove, rings 3 are located the outside of disk seat 2, be equipped with dish spring 5 between rings 3 and the disk seat 2, the hole diameter of dish spring 5 is greater than rings 3's hole diameter, the front side terminal surface of disk seat 2 is equipped with annular boss 6, the cover of dish spring 5 is established on annular boss 6.

As a further improvement of the technical scheme, an adjusting gap is arranged between the front end surface of the annular boss 6 and the hanging ring 3.

As a further improvement of the above technical solution, the outer edge of the disc spring 5 abuts against the inner end of the hanging ring 3.

As a further improvement of the above technical scheme, the end face of the hanging ring 3 is provided with a plurality of threaded holes located on the same circumference, adjusting bolts 7 are arranged in the threaded holes, and the end parts of the adjusting bolts 7 abut against the outer edge of the disc spring 5.

As a further improvement of the above technical solution, an annular sealing groove is provided on the outer circumferential surface of the valve seat 2, and a sealing ring 8 is disposed in the annular sealing groove.

When the sealing effect of the valve seat and the opening and closing piece is reduced in the using process, the elastic force adjusting valve seat of the disc spring is close to the opening and closing piece, so that the sealing effect is enhanced; when the elasticity of the disc spring cannot act, the elasticity of the disc spring is increased by rotating the adjusting bolt, so that the sealing effect of the valve seat and the opening and closing piece is further enhanced.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
