DETAILED DESCRIPTION OF THE EMBODIMENTS:

[0024] The present utility model will be further described below in conjunction with the drawings in terms of specific embodiments:

[0025] As shown Figures 1-7 in the figure, a dual-purpose ball valve includes a valve body 6 and a sealing ball 4 disposed inside the valve body 6. The valve body 6 is a three-way valve body. An inlet 61, an upper outlet 62, and a lower outlet 63 that communicate with each other are provided on the valve body 6. The upper outlet 62 and the lower outlet 63 are coaxially arranged and face in opposite directions. The inlet 61 forms a 90° angle with the upper outlet 62 and the lower outlet 63 respectively. An inlet hole 41 and an outlet hole 42 are provided on the sealing ball 4. The inlet hole 41 and the outlet hole 42 are counterbored holes. The inlet hole 41 and the outlet hole 42 communicate with each other. Among them, the inlet hole 41 faces the inlet 61, and the outlet hole 42 forms a 90° angle with the inlet hole 41. A rotating shaft 7 is also connected to the side of the sealing ball 4 opposite to the inlet hole 41. The rotating shaft 7 penetrates through the valve body 6 and extends outward. One end of the rotating shaft 7 extending outside the valve body 6 is also connected to a handle 9. During use, the handle 9 is rotated to drive the rotating shaft 7 to drive the sealing ball 4 to rotate, so as to close the valve body 6 or open the upper outlet 62 or the lower outlet 63 of the valve body 6.

[0026] In this embodiment, water outlet connectors 1 are respectively threadedly connected to the upper outlet 62 and the lower outlet 63. Sealing rings 2 and positioning rings 3 are respectively provided between the upper and lower water outlet connectors 1 and the sealing ball 4, and the sealing ball 4 is positioned by the upper and lower positioning rings 3. The positioning ring 3 has a groove adapted to the sealing ball 4.

[0027] Now, the specific usage scenarios will be further described. In this embodiment, the lower outlet 63 of the dual-purpose ball valve is connected to the washing machine water inlet pipe on the balcony, and the upper outlet 62 is connected to a spray gun for description. As Figure 2 shown in the figure, after the valve body 6 is installed, when the handle part of the handle 9 is in the horizontal position, the valve body is in the closed state. At this time, the outlet hole 42 of the sealing ball 4 faces the front of the valve body 6 and is not connected to both the upper outlet 62 and the lower outlet 63; as Figure 3 shown in the figure, when the handle 9 is rotated counterclockwise by 90 degrees, the valve body 6 is opened. At this time, the outlet hole 42 of the sealing ball 4 is connected to the upper outlet 62, and the dual-purpose ball valve is in the upper water outlet state. The spray gun connected to the upper outlet 62 can work at this time for flushing the balcony, etc.; and when the handle 9 is rotated clockwise by 90 degrees in the closed state, the valve body 6 is also opened. At this time, the outlet hole 42 of the sealing ball 4 is connected to the lower outlet 63, and the dual-purpose ball valve is in the lower water outlet state. The washing machine connected to the lower outlet 63 can intake water at this time. It should be noted that no matter what state it is in, the inlet hole 41 of the sealing ball 4 is connected to the inlet 61 of the valve body 6.

[0028] As an implementation manner, a positioning groove 43 is further provided on one side of the sealing ball 4 connected to the rotating shaft 7. One end of the rotating shaft 7 connected to the sealing ball 4 is inserted into the positioning groove 43 and is clamped with it. Among them, the upper and lower surfaces of one end of the rotating shaft 7 connected to the sealing ball 4 have flat positions. The rotating shaft 7 is connected to the handle 9 through these flat positions and is clamped with the card slot 91 on the handle 9.

[0029] As Figure 5 shown, a positioning rib 64 cooperating with the handle 9 is provided on the outer peripheral surface of the valve body 6. In this embodiment, the coordinates of the positioning rib 64 are in the X-axis direction, and the handle 9 is limited by the positioning rib 64. Correspondingly, one end of the handle 9 close to the valve body 6 has a limiting protrusion 92, and the limiting protrusion 92 cooperates with the positioning rib 64. The limiting protrusion 92 is in a semi-circular ring shape.

[0030] As an implementation manner, as Figure 7 shown, an arrow indicating the water outlet direction is also recessed on the handle 9, which is more convenient for the operator to use.

[0031] In addition, like the existing angle valve, the present utility model also includes a decorative cover 5. The decorative cover 5 is sleeved on the outer peripheral surface of the water inlet 61 and is used for connecting the ball valve and the wall where the external water inlet pipe is located. The decorative cover 5 has a structure of the prior art.

[0032] The above only describes the preferred embodiments of the present utility model, but it should not be construed as a limitation to the claims. Any equivalent structure or equivalent process transformation made using the description of the present utility model is included in the patent protection scope of the present utility model.
