[0024] First, place sealing gaskets 4 on both sides of the three-way valve ball 3, take out the valve bonnet 2 and screw it with the valve body 1, fit the long pipe 20 with the valve bonnet 2, take out the long pipe bonnet 11 and screw it with the valve bonnet 2 to achieve the positioning and installation of the long pipe 20. After the lower part of the device is fitted with the pipeline, the positioning and installation are achieved by screwing the union cap 18 and clamping the flat gasket 19 to achieve the sealing of the pipeline. The hose is put on the outside of the drain pipe 22 to achieve quick connection. After screwing the sealing rod 21, the sealing rod 21 can be moved left and right in the valve body 1, so that the left channel can be opened and water can flow from the drain pipe 22. Turning the handle 9 can drive the valve stem 5 to rotate, and the valve stem 5 drives the three-way ball valve 3 to rotate, so that the ball valve with a T-shaped channel changes the position of the through hole to achieve the opening and closing of the vertical pipeline.

[0025] In one embodiment, please refer to the attached specification Figure 1-2 As a further solution of the utility model, sealing gaskets 4 are installed at the upper and lower ends of the outer side of the three-way valve ball 3, and the sealing gaskets 4 are symmetrically arranged in the upper and lower parts.

[0026] The sealing gasket 4 can ensure the seal between the three-way valve ball 3 and the valve body 1, so that when the three-way valve ball 3 is closed, water will not overflow.

[0032] The sealing between the sealing rod 21 and the valve body 1 is achieved by providing three groups of O-rings, so that the sealing rod 21 can be sealed when opened or closed to avoid leakage.

[0033] In one embodiment, please refer to the attached specification Figure 1-2 As a further solution of the utility model, the core pressure cap 17 is spirally connected to the valve body 1 , and a fourth O-ring 16 is installed at the connection between the core pressure cap 17 and the valve body 1 .

[0034] The sealing rod 21 is positioned by the core pressing cap 17 .

[0035] During use, before assembly, all parts should be kept clean and free of dirt, metal fragments, burrs, flash, etc. The threaded connection end of the valve cap should be coated with an appropriate amount of sealant. The valve should open and close flexibly without obstruction. When the ball valve is fully open, the angle between the axis of the ball through hole and the axis of the valve body through hole should not be greater than 3°. A sealing test should be carried out and the test pressure should not be less than 0.6MPa. First, place sealing gaskets 4 on both sides of the three-way valve ball 3, take out the valve bonnet 2 and screw it with the valve body 1, fit the long pipe 20 with the valve bonnet 2, take out the long pipe bonnet 11 and screw it with the valve bonnet 2 to achieve the positioning and installation of the long pipe 20. After the lower part of the device is fitted with the pipeline, the positioning and installation are achieved by screwing the union cap 18 and clamping the flat gasket 19 to achieve the sealing of the pipeline. The hose is put on the outside of the drain pipe 22 to achieve quick connection. After screwing the sealing rod 21, the sealing rod 21 can be moved left and right in the valve body 1, so that the left channel can be opened and water can flow from the drain pipe 22. Turning the handle 9 can drive the valve stem 5 to rotate, and the valve stem 5 drives the three-way ball valve 3 to rotate, so that the ball valve with a T-shaped channel changes the position of the through hole to achieve the opening and closing of the vertical pipeline.

[0036] A drainage hole is provided at the bottom of the valve body and is connected to the connecting channel. This design can realize the drainage function of the three-way ball valve without increasing the installation space and cost, and improve the convenience and reliability of the three-way ball valve. When it is necessary to switch between different pipelines, the ball can be rotated in the valve body by operating the joystick to realize the connection and disconnection between different pipe openings. When drainage is required, the drainage hole is opened to discharge the medium from the drainage hole, effectively removing impurities and accumulated water in the pipeline.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
