[0023] A visible flow window 130 is opened on the side wall of the valve body 100 between the water pipe joint 300 and the bypass joint 400. A tubular transparent cover 131 is installed inside the valve body 100 to match the flow window 130. A flow scale 132 is arranged on the outer wall of the transparent cover 131 at the flow window 130. The transparent cover 131 is tightly attached to the inner wall of the pipe inside the valve body 100, and sealing rings are installed at both ends of the transparent cover 131 for sealing to prevent leakage of the flow valve.

[0024] A flow spring 140 and a flow buoy 141 are installed inside the transparent cover 131 between the water pipe joint 300 and the bypass joint 400. The flow buoy 141 is pressed against the water inlet of the water pipe joint 300 by the elastic force of the flow spring 140, and rises after being impacted by the water flow, corresponding to the flow scale 132 at the flow window 130 for the user to read intuitively. The visualization of flow changes can facilitate users to observe the flow size and changes to determine whether the water system is operating normally, and to detect problems such as water leakage and clogging in time.

[0025] like Figure 2 and Figure 3As shown, a three-way ball 120 is arranged inside the valve body 100 at the intersection of the valve body 100 and the bypass joint 400. The three-way ball 120 is connected to the water inlet switch 110 outside the valve body 100. A first ball groove 124 is provided at the connection between the three-way ball 120 and the water inlet switch 110. The end of the water inlet switch 110 extends into the first ball groove 124 to control it. A plurality of first sealing rings 112 are installed at the connection between the outer wall of the water inlet switch 110 and the inner wall of the valve body 100 to ensure the sealing of the inside of the valve body 100 and prevent water leakage and pressure relief.

[0026] The three-way sphere 120 is provided with openings a121, b122 and c123 respectively. By rotating the water inlet switch 110 to change the pipeline paths corresponding to the openings a121, b122 and c123, the flow valve can be switched between water inlet, drainage, cleaning and other functions. The knob of the water inlet switch 110 is provided with a switch slot 111.

A switch handle 411 is formed on the drainage switch 410, and the two-way sphere 420 can be controlled to rotate by rotating the switch handle 411 to change whether the openings d421 and e422 are connected to the bypass pipeline. A plurality of second sealing rings 412 are installed at the junction of the outer wall of the drainage switch 410 and the inner wall of the bypass joint 400 to ensure the sealing inside the bypass joint 400.

[0028] The working principle of the utility model is as follows: the multifunctional water-saving flow valve controls the three-way ball 120 and the two-way ball 420 respectively by screwing the water inlet switch 110 and the drainage switch 410, so as to switch the pipeline according to different needs such as water inlet, drainage, cleaning, etc.

[0029] In the water inlet state, the opening a121 of the three-way sphere 120 corresponds to the circulation pump interface 200, the opening b122 corresponds to the bypass joint 400, the opening c123 corresponds to the water pipe joint 300, the drain switch 410 is in the closed state, and the internal passage of the sphere formed by the opening d421 and the opening e422 of the two-way sphere 420 is perpendicular to the internal pipeline of the bypass joint 400. At this time, water flows in from the water pipe joint 300, impacts the flow buoy 141 and compresses the flow spring 140. The user can observe the flow scale 132 corresponding to the flow buoy 141 through the flow window 130 to read the flow, and the water flows into the circulation pump through the opening c123, the opening a121 and the circulation pump interface 200.

At this time, the wastewater in the circulation pump passes through the circulation pump interface 200, the opening b122, the opening c123, the opening e422 and the opening d421 in sequence, and is finally discharged from the port of the bypass joint 400.

[0031] In the cleaning state, the opening a121 of the three-way ball 120 corresponds to the bypass joint 400, the opening b122 corresponds to the water pipe joint 300, the opening c123 corresponds to the inner wall of the valve body 100, the drain switch 410 is in the open state, the inner passage of the ball formed by the opening d421 and the opening e422 of the two-way ball 420 is coaxially connected with the internal pipeline of the bypass joint 400, and the bypass sealing cover 430 is in the open state. At this time, water flows in from the water pipe joint 300, passes through the flow buoy 141, the flow spring 140, the opening b122, the opening a121, the opening e422 and the opening d421 in sequence, and is finally discharged from the port of the bypass joint 400, thereby cleaning the inside of the valve body 100.
