The water outlet channel 14 and the water inlet channel 15 are both connected with the water passage chamber 5, and the inner walls of the water outlet channel 14 and the water inlet channel 15 are provided with abutment rings 16 integrally formed with the valve body 1 near the water passage chamber 5, and the outer walls of the water outlet channel 14 and the water inlet channel 15 are provided with rotating components 2, and a group of collinear movable holes 17 are opened in the middle position of each rotating component 2 on the valve body 1, and linkage components 3 are provided in the movable holes 17, and the bottom of the linkage components 3 are hinged with a positioning component 4.

[0025] In the utility model, the rotating assembly 2 includes a fixed ring 201, which is integrally formed with the valve body 1. An annular T-shaped groove 202 is provided on the side of the fixed ring 201 away from the water passage chamber 5. A rotating ring 203 is provided on the end of the fixed ring 201 away from the water passage chamber 5. A group of annular T-shaped sliders 204 are provided on the end of the rotating ring 203 close to the fixed ring 201. The rotating ring 203 is rotatably connected to the outer wall of the valve body 1 through the sliding connection between the T-shaped slider 204 and the T-shaped groove 202. A group of stepped grooves 205 are provided on the side of the rotating ring 203 close to the fixed ring 201, and the stepped surface of the groove 205 is set as an arc surface 206.

[0026] In the above technical scheme, the rotating ring 203 is rotatably connected to the fixed ring 201 by utilizing the sliding connection between the T-shaped slider 204 and the T-shaped groove 202, and a stepped groove 205 is opened on the rotating ring 203, and the stepped surface of the groove 205 is set to an arc surface 206, so that when the rotating ring 203 rotates, the stepped groove 205 will generate an extrusion force on the ball slider 303 in the linkage assembly 3, and the set arc surface 206 facilitates the sliding of the ball slider 303 in the groove 205.

[0027] In the utility model, the linkage assembly 3 includes a telescopic rod 301, and a group of abutment surfaces 302 are provided on the outer walls of the water outlet channel 14 and the water inlet channel 15 at the side position of the fixed ring 201 at one end away from the water chamber 5. The group of abutment surfaces 302 corresponds to a group of movable holes 17, and each abutment surface 302 corresponds to each groove 205 respectively. The telescopic rod 301 is penetrated into the movable hole 17, and a ball slider 303 is provided at one end of the telescopic rod 301 close to the groove 205. The ball slider 303 is located in the groove 205 and slidably abuts therewith. A spring 304 is sleeved on the telescopic rod 301, one end of the spring 304 abuts on the ball slider 303, and the other end of the spring 304 abuts on the abutment surface 302. A first hinge block 305 is provided at the bottom of the telescopic rod 301.

[0028] In the above technical scheme, the telescopic rod 301 is passed through the movable hole 17, a ball slider 303 is arranged on the top of the telescopic rod 301, and a spring 304 is sleeved on the telescopic rod 301 between the ball slider 303 and the abutment surface 302, so that when the rotating ring 203 rotates, when the ball slider 303 rotates to the lower position in the stepped groove 205, the ball slider 303 will be squeezed, so that the telescopic rod 301 will extend into the water inlet channel 15 and the water outlet channel 14. At this time, the spring 304 is compressed by the squeezing force. When the ball slider 303 rotates to a higher position in the stepped groove 205, the ball slider 303 will lose the squeezing force. At this time, the spring 304 loses the squeezing force and rebounds to reset, so that the telescopic rod 301 returns to its original position under the action of the spring 304.

[0029] In the present invention, the positioning assembly 4 includes a second hinge block 401, and the second hinge block 401 is rotatably connected to the first hinge block 305. A group of receiving grooves 402 are provided on the inner wall of the water outlet channel 14 and the water inlet channel 15, which are away from the abutment ring 16 of the water passage chamber 5. The group of receiving grooves 402 respectively corresponds to the position of each movable hole 17, and a group of positioning plates 403 are hinged in the storage grooves 402. The positioning plates 403 correspond to the movable holes 17 on one side of the inner wall of the water outlet channel 14 or the water inlet channel 15. A second T-shaped groove 404 is provided at the position of the hole 17, a slide plate 405 is provided in the second T-shaped groove 404, a second hinge block 401 is fixedly connected to the side of the slide plate 405 away from the positioning plate 403, a sealing ring 18 is provided on the side of the abutment ring 16 away from the water chamber 5, a water pipe 19 is provided on the side of the sealing ring 18 away from the abutment ring 16, a convex ring 20 is provided on the outer wall of the water pipe 19 near the sealing ring 18, and the side of the positioning plate 403 close to the convex ring 20 can abut on the convex ring 20.

[0030] In the above technical scheme, the second hinge block 401 slidably connected to the slide plate 405 in the second T-shaped slide groove 404 is rotatably connected with the first hinge block 305 arranged at the bottom of the telescopic rod 301, so that the telescopic movement of the telescopic rod 301 can drive the positioning plate 403 to move. When the ball slider 303 rotates to the lower position in the stepped groove 205, the ball slider 303 is squeezed, so that the telescopic rod 301 extends into the water inlet channel 15 and the water outlet channel 14. At the same time, the positioning plate 403 hinged in the storage groove 402 will rotate out of the storage groove 402 under the telescopic force of the telescopic rod 301 and abut against the convex ring 20 on the water pipe 19 to fix the water pipe 19.

[0031] In the utility model, in order to prevent water from seeping into the valve through the gap between the valve cover 9 and the valve stem 12, a filling groove 21 is provided inside the valve cover 9, and a filler 22 for sealing and preventing water seepage is provided inside the filling groove 21. A protective block 23 is provided on the top of the filler 22 inside the filling groove 21 to prevent the filler 22 from rotating and falling, and the protective block 23 is detachably connected to the valve cover 9.

[0032] The working principle of the utility model of a valve which is easy to install is:

[0033] During installation, first ensure that the ball slider 303 is located at a higher position inside the groove 205, and the spring 304 is in a stress-free state. Then, the water pipe 19 and the sealing ring 18 are simultaneously inserted into the water inlet channel 15, so that the sealing ring 18 and one end of the convex ring 20 of the water pipe 19 are simultaneously squeezed on the abutment ring 16 and continuously squeezed. Then, the rotating ring 203 is rotated. At this time, the T-shaped slider 204 slides in the T-shaped slide groove 202, and the ball slider 303 slides across the arc surface from the high position in the groove 205. 206 moves to the lower position in the groove 205. During this process, the groove 205 generates an extrusion force on the ball slider 303, the spring 304 is compressed, and the telescopic rod 301 extends into the water inlet channel 15, driving the locking plate 403 located in the receiving groove 402 to rotate out of the receiving groove 402 near one end of the water passage chamber 5 and abut against the convex ring 20 of the water pipe 19, which will lock and fix the water pipe 19 inside the water inlet channel 15; the water pipe 19 can be connected to the water outlet channel 14 in the same way.

[0034] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
