Detailed ways

The present application will be further described below with reference to specific embodiments.

As shown in Fig. 1-3, which is a schematic diagram of the structure of this embodiment, this embodiment includes a ball valve core 1, a valve core connecting block 2 and a valve core driving member 3, and the ball valve core 1 is arranged in the pipeline 4, One end of the valve core connecting block 2 is fixedly connected with the ball valve core 1, and the other end extends out of the pipeline 4 and is connected with the valve core driving member 3. A valve core positioning member 5 is arranged above the valve core driving member 3, and the valve core positioning member The positioning block 51 in 5 is connected with the valve core driver 3 by screws.

In this embodiment, the top end surface of the valve core driving member is provided with a first screw hole 31, and the positioning block 51 is provided with a second screw hole 511. The end surface of the first screw hole 31 is larger than the end surface of the second screw hole 511. The first screw hole 31 is provided with a spring 32, the spring 32 extends out of the first screw hole 31 and is connected to the bottom of the positioning block 51, and the first screw hole 31, the second screw hole 511 and the spring 32 are concentric, so when the positioning block 51 After the screw with the valve core driver 3 is loosened, the elastic force of the spring 32 will push up the positioning block 51, thereby driving the entire valve core positioning member 5 to lift up. At this time, the ball type can be adjusted by adjusting the valve core driving member 3. The angle between the valve core 1 and the pipe 4 can adjust the size of the water flow.

In this embodiment, the valve core positioning member 5 includes a positioning block 51 and clamping arms 52 opposite to both ends of the positioning block 51. The straight line formed by the positioning block 51 and the clamping arms 52 is parallel to the pipeline 4, and the clamping arms 52 includes a connecting arm 521, a transverse arm 522 and a vertical arm 523 that are fixedly connected with the positioning block 51. The connecting arm 521 is fixedly connected to the positioning block 51 parallel to the pipeline 4, and the transverse arm 522 is perpendicular to the connecting arm 521 and is fixedly connected to the connecting arm 521. , the vertical arm 523 is vertically arranged at both ends of the transverse arm 522 .

In this embodiment, the transverse arm 522 adopts an elastic structure that stretches outward and contracts inward. According to the radial length of the pipeline 4, the vertical arm 523 can be used to clamp the pipeline 4, and the vertical arm 523 is connected to the pipeline 4. An elastic rubber pad is arranged on the end point of the pipe 4 to ensure that the clamping of the pipe 4 by the vertical arm 523 is not rigid, and will not cause damage to the outer wall of the pipe 4 and the end of the vertical arm 523 .

When this embodiment is in operation, the staff controls the size of the water flow through the ball valve core 1 by operating the valve core connecting block 2 connected to the ball valve core 1, and after adjusting in place, the valve core positioning member 5 is fixed by screws. Connected with the valve core driver 3, at this time, the clamping arms 52 on the valve core positioning member 5 clamp both ends of the pipeline 4 to realize the positioning of the valve core driving member 3, so as to ensure that the ball valve core 1 will not be affected. The impact of the impact of the water flow will cause displacement. When the water flow needs to be re-adjusted, it is only necessary to loosen the screw. The spring 32 in the first screw hole 31 in the valve core driver 3 will bounce the positioning block 51, and the valve core driver 3 and the When the positioning block 51 is released, the valve core driving member 3 can be readjusted to adjust the size of the water flow through the ball valve core 1 .
