[0024] Refer to Figure 4 , the side of the eccentric disc 11 away from the mounting block 10 is fixedly connected with the second rotating rod 12, the second rotating rod 12 is away from the eccentric disc 11, forming an eccentric structure, so that when the eccentric disc 11 slides under the guidance of the mounting block 10, due to the design of the eccentric disc 11, the pressure rod 4 will be driven to swing, the end of the second rotating rod 12 away from the eccentric disc 11 is fixedly connected with the first valve 13, the outer wall of the second rotating rod 12 is rotatably connected with the inner wall of the installation shell 2, the end of the first rotating rod 9 away from the lead screw 8 is fixedly connected with the second valve 14, the surface of the first valve 13 and the second valve 14 is integrally formed with anti-skid particles, the materials of the first valve 13 and the second valve 14 are anti-skid materials, the anti-skid particles integrally formed on the surface of the first valve 13 and the second valve 14 can increase the friction between the staff and the assembly, so that the operator can stably hold and rotate the first valve 13 and the second valve 14 in the case of wet, greasy or emergency operation, avoiding the operation failure or safety accident caused by slipping.

[0025] The second connecting rod 15 is rotatably connected to one end of the pressing rod 4 away from the first connecting rod 3, and the push rod 16 is rotatably connected to one end of the second connecting rod 15 away from the pressing rod 4. The pressing rod 4 is rotatably connected to the push rod 16 through the second connecting rod 15, so as to convert the up-down movement of the pressing rod 4 into the linear movement of the push rod 16, reduce the energy loss in the movement process, and improve the output efficiency of the assembly. The second connecting rod 15 as an intermediate transmission component allows a certain angle change between the pressing rod 4 and the push rod 16, increases the flexibility between the components, and the sliding connection between the outer wall of the push rod 16 and the inner wall of the mounting shell 2 enables the push rod 16 to slide along a predetermined trajectory, ensuring the stability during operation. The bottom end of the push rod 16 is fixedly connected with the plug 17, and the plug 17 is made of wear-resistant material. The wear-resistant material can keep the shape and size of the plug 17 stable during long-term use, thereby prolonging the service life of the valve body 1 and ensuring the tight sealing of the valve body 1.

[0026] Both ends of the valve body 1 are bolted with the pipelines 18, and the inside of each pipeline 18 is connected with the valve body 1. One of the pipelines 18 is used for input work, and the other pipeline 18 is used for output work, so as to realize the flow work inside the valve body 1 and ensure the smoothness of the whole assembly during operation.

[0027] Working principle: the staff rotates the first valve 13 to make the second rotating rod 12 rotate in the inner wall of the mounting shell 2. The threads on the outer wall of the second rotating rod 12 cooperate with the threads on the inner wall of the mounting shell 2 to produce only rotation without linear displacement, thereby driving the eccentric disc 11 to rotate. The eccentric characteristic of the eccentric disc 11 drives the pressing rod 4 to swing up and down, and the swing of the pressing rod 4 drives the push rod 16 and the plug 17 to adjust the flow of the inner wall of the valve body 1. By twisting the second valve 14, the first rotating rod 9 and the lead screw 8 can be rotated. When the lead screw 8 rotates, the adjusting block 7 moves horizontally along the axis of the lead screw 8, so that the sliding block 6 slides in the inner wall of the guide sliding groove 5, thereby adjusting the maximum and minimum threshold of the stroke of the pressing rod 4. The whole adjusting assembly is a reciprocating motion. Compared with the traditional assembly, the traditional assembly needs to frequently switch the rotation direction, while the eccentric characteristic of the eccentric disc 11 only needs to rotate in one direction to realize the adjusting action, which simplifies the operation process. By using the maximum and minimum threshold of the adjusting stroke of the sliding block 6 and the adjusting block 7, more efficient water flow distribution and adjustment are realized, the utilization of water resources is optimized, and unnecessary waste is reduced.
