Abstract

The utility model discloses a ball valve, including the feed liquor interface, go out the liquid interface, the valve body, the both ends opening of valve body, the both ends of valve body respectively with the feed liquor interface with go out the liquid interface and be connected, the flow path that has intercommunication feed liquor interface in the valve body and go out the liquid interface, spheroid, spheroid set up in the valve body, through coming the switching around the axis of reference rotation the flow path, operating device, operating device are used for making the spheroid is rotatory around the axis of reference, the disk seat of two rings form sets up in the both ends of valve body just all closely balancedly with the spheroid respectively, the periphery wall of two disk seats on all be provided with an annular groove that extends along the radial direction of disk seat. The utility model discloses the resistance that the disk seat was applyed the spheroid when making the spheroid rotate is less.

Description

Ball valve

Technical field

This utility model relates to a kind of ball valve.

Background technology

Current ball valve generally comprises feed liquor interface, go out liquid interface and valve body, the both ends open of valve body, the two ends of valve body respectively with feed liquor interface and go out liquid interface and be connected, there is in valve body connection feed liquor interface and go out the stream of liquid interface, spheroid it is provided with in valve body, spheroid by rotating the stream in open-close valve around reference axis, valve rod it is provided with on valve body, described spheroid can be made to rotate around reference axis by rotation valve rod, two ring-type valve seats it are provided with in valve body, two valve seats are respectively arranged at the two ends of valve body and all closely offset with spheroid, spheroid is when rotating, spheroid end face with two valve seats all the time offsets, so, when spheroid rotates, valve seat can apply bigger resistance to spheroid, valve seat is made to hinder spheroid to rotate, the operating handle making this ball valve is poor.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of ball valve, and the resistance that when it makes spheroid rotate, spheroid is applied by valve seat is less.

For solving above-mentioned technical problem, the ball valve that this utility model provides, including:

Feed liquor interface;

Go out liquid interface;

Valve body, the both ends open of valve body, the two ends of valve body respectively with feed liquor interface and go out liquid interface and be connected, there is in valve body connection feed liquor interface and go out the stream of liquid interface,

Spheroid, spheroid is arranged in valve body, by rotating stream described in opening and closing around reference axis;

Operating mechanism, operating mechanism is used for making described spheroid rotate around reference axis;

Two ring-type valve seats, are respectively arranged at the two ends of valve body and all closely offset with spheroid;

An annular groove extended along the radial direction of valve seat it is provided with on the periphery wall of two described valve seats.

As preferably, the degree of depth of described annular groove is 1:5 with the ratio of the radial width of valve seat.

As preferably, the degree of depth of described annular groove is 1mm, and the radial width of described valve seat is 5mm.

As preferably, the width of described annular groove is 0.8mm, and the thickness of described valve seat is 4mm.

After using above structure, this utility model compared with prior art, has the advantage that

In ball valve of the present utility model, being provided with the annular groove of the radial direction extension along valve seat on the periphery wall of valve seat, so, the axially deformable amount allowing for valve seat increases, namely increase the axial elasticity of valve seat, so, when spheroid rotates, spheroid is so that valve seat is axially compressed, so, when spheroid rotates, it is possible to reduce the resistance that spheroid is applied by valve seat so that the operating handle of this ball valve is preferable.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model ball valve;

Fig. 2 is the structural representation of valve seat.

Detailed description of the invention

With detailed description of the invention, this utility model is described in more detail below in conjunction with the accompanying drawings.

Shown in Fig. 1, Fig. 2, this utility model ball valve includes feed liquor interface 1, goes out the valve seat 5 that liquid interface 2, valve body 3, spheroid 4, operating mechanism and two are ring-type.

The both ends open of valve body 3, the two ends of valve body 3 respectively with feed liquor interface 1 and go out liquid interface 2 and be connected, there is in valve body 3 connection feed liquor interface 1 and go out the stream of liquid interface 2.

Spheroid 4 is arranged in valve body 3, and spheroid 4 is by rotating stream described in opening and closing around reference axis.

Operating mechanism is used for making described spheroid rotate around reference axis, and described operating mechanism includes a valve rod 6, spheroid 4 can be driven to rotate around reference axis by pulling valve rod 6 rotation.

Two valve seats 5 are respectively arranged at the two ends of valve body and all closely offset with spheroid 4, and spheroid 4 is when rotating, and the two ends of spheroid 4 offset with two valve seats 5 all the time.

Being provided with an annular groove 501 extended along the radial direction of valve seat 5 on the periphery wall of two described valve seats 5, radial groove 501 is so that valve seat 5 can be by being compressed axially by a relatively large margin.

The degree of depth of described annular groove 501 is 1:5 with the ratio of the radial width of valve seat 5.

The degree of depth of described annular groove 501 is 1mm, and the radial width of described valve seat 5 is 5mm.

The width of described annular groove 501 is 0.8mm, and the thickness of described valve seat 5 is 4mm.

Being provided with a skew wall 502 on the end face of two valve seats 5, skew wall 502 is for offseting with spheroid 4.

Below only applying preferably example to be made that explanation with regard to this utility model, but be not to be construed as limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes made in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
