The system can better adapt to different application scenes and requirements, and the universality and the adaptability of the system are improved.

Referring to fig. 4 and 5, according to an embodiment of the present invention, a step 115 is provided on an inner wall of an end of the outer valve body 110 provided with the receiving opening 114, and a protrusion 122a is protruded in a radial direction from an outer circumferential wall of the inner valve body 120, and the protrusion 122a abuts against the step 115. It will be appreciated that by providing the step 115 and the protrusion 122a, the assembly of the inner valve body 120 with the outer valve body 110 is simplified and accurate. In the assembly process, the protrusion 122a of the inner valve body 120 is aligned with the step 115 of the outer valve body 110, and then a proper force is applied to tightly abut the protrusion 122a against the step 115, so that the inner valve body 120 and the outer valve body 110 can be fixedly connected.

Simplifying the on-off setting of the valve opening and closing opening 123b and improving the reliability and stability of waterway control. When the abutment 210 moves away from the valve opening 123b, it changes the opening of the valve opening 123b, thereby realizing the conduction of the waterway. At this time, the water flow can flow into the inner valve cavity 121 from the second valve port 113, and then flow out towards the first valve port 112 through the inner valve port 123a, so as to realize the conduction of the water flow. Conversely, when the abutment 210 moves toward the valve opening and closing opening 123b, it closes the valve opening and closing opening 123b, thereby achieving the closure of the waterway.

It can be appreciated that the design of the elastic member 500 allows the abutment member 210 to automatically return to the original state, providing stability and reliability for the control of the waterway. When the control signal is changed, the abutment 210 is moved accordingly to change the opening degree of the valve opening and closing opening 123 b. The elastic member 500 is used for providing a restoring force, so that the abutment member 210 can automatically restore to the initial position after the control signal is released. In this way, by introducing the elastic member 500 into the control assembly 200, the restoring force of the abutment member 210 against the valve opening and closing port 123b is provided, and stability and reliability of waterway control are achieved.

Referring to fig. 4 and 5, according to an embodiment of the present invention, the outer circumferential wall of the inner valve body 120 is provided with a radially protruding abutment boss 122b, the abutment 210 is axially sleeved with the barrier 300, and the elastic member 500 abuts between the barrier 300 and the abutment boss 122 b. It will be appreciated that the function of the resilient member 500 is to provide a restoring force so that the abutment 210 can automatically return to the initial position. By abutting the elastic member 500 between the shutter 300 and the abutment boss 122b, the restoring force of the elastic member 500 can be effectively utilized, ensuring that the abutment member 210 is stably held at a specific position. When triggered by a control signal, the abutment 210 moves axially under the protection of the shutter 300. The elastic member 500 provides a necessary restoring force to enable the abutment member 210 to quickly return to the initial position after the control signal is released.

Referring to fig. 1 and 2, the waterway control system 10 further includes a driving assembly 600, and one end of the abutment 210 protrudes from the inner valve cavity 121 to movably abut the driving assembly 600 according to one embodiment of the present invention. It will be appreciated that the drive assembly 600 is capable of driving the abutment 210 for axial movement, thereby effecting control of the valve opening and closing 123 b. By abutting the drive assembly 600, the abutment 210 is able to receive power from the drive assembly 600, enabling precise axial movement. Alternatively, the drive assembly 600 may take a variety of forms, such as an electric motor, a pneumatic device, or a hydraulic system, among others. An appropriate driving manner may be selected to drive the abutment 210 according to the requirements of the actual application.

Referring to fig. 4 and 5, according to an embodiment of the present invention, the abutment member 210 includes an abutment end 211 and a pressing end 212 disposed opposite to each other in the axial direction of the outer valve body, and the pressing end 212 protrudes from the inner valve cavity 121 to movably abut against the driving assembly 600, so as to drive the abutment end 211 to move in the axial direction of the outer valve body, thereby opening the valve opening and closing port 123b. It will be appreciated that when the drive assembly 600 receives a control signal, it will drive the push end 212 to move. The movement of the pressing end 212 further drives the abutting end 211 to move along the axial direction of the outer valve body. Movement of the abutment end 211 changes the opening degree of the valve opening/closing port 123b, thereby realizing conduction or blocking of the waterway. The waterway control system 10 can be precisely controlled according to actual demands, and the flexibility and adaptability of the system are improved.
