Abstract
The utility model discloses an adjustable ball valve. The adjustable ball valve comprises a valve body and a spherical valve arranged in the valve body, wherein a through hole is formed in the valve body; a channel which is matched with the through hole is formed in the spherical valve; a connecting part is arranged in the through hole; the adjustable ball valve also comprises a connecting piece for installing the spherical valve; an internal thread is formed on the connecting part; an external thread is formed on the connecting piece; and the connecting part is matched with the connecting piece through the threads. The adjustable ball valve has a simple structure; the spherical valve is arranged in the connecting piece and is in threaded connection with the valve body; the sealing performance between the spherical valve and the valve body can be effectively improved; the relative position between the spherical valve and the valve body can be properly adjusted by the connecting piece, so that an adjustable function is realized, and the practicability is high; and a sealing piece is arranged between the connecting piece and the connecting part, so that the sealing performance of the adjustable ball valve is further improved.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of adjustable ball valve.
Background technique
The structure of existing adjustable ball valve mostly comprises valve chamber, communicate with valve chamber, the end is provided with valve pipe interfacing part, that the end is fixedly connected with the two ends of valve chamber, place valve ball valve chamber, that have passage on it, be connected with valve ball, the end stretches out the valve rod of valve chamber outside; Interfacing part is generally metallic shim, and the middle part of this metallic shim has through hole, and the shape in through hole cross section, size are identical with passage on the valve ball, and like this, operating valve lever makes the passage on the valve ball be communicated with the through hole of metallic shim, and valve just is in the state of unlatching; Because interfacing part is fixedly connected with the end of valve pipe, in case moulding, gap therebetween can't be regulated, so in case the passage on the valve ball docks imprecision with the through hole of metallic shim, will make valve closing not tight, causes the generation of run, drip, leak phenomenon; Valve rod generally also is by offering connecting groove at valve ball with being connected of valve ball, by connecting groove valve rod and valve ball are linked together again, so, in case connecting groove damages, in this case again during operating valve lever, just can't realize the rotation of valve ball, in a single day this situation occurs, and this valve has just been scrapped.
Summary of the invention
The purpose of this utility model provides a kind of adjustable ball valve of simple in structure, good seal performance.
The technological scheme that realizes the utility model purpose is a kind of adjustable ball valve, comprise valve body, be arranged on the spherical valve in the valve body, be provided with through hole in the described valve body, described spherical valve is provided with the passage that matches with described through hole, be provided with joint in the described through hole, also comprise the link that spherical valve is installed, described joint is provided with internal thread, described link is provided with outside thread, described joint and described link screw-thread fit.
Be provided with Sealing between described link and the joint.
The utlity model has positive effect: of the present utility model simple in structure, spherical valve is installed in the link and with valve body screw thread and is connected, can effectively improve the sealability between spherical valve and the valve body, and by the suitable relative position of regulation ball valve and valve body of link, realize adjustable function, practicability is good; And between link and joint, be provided with Sealing, further improved its sealability.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present utility model.
