[0018] This application provides a T-type three-way ball valve, which solves the limitations of traditional T-type three-way ball valves in use. Because the T-type three-way ball valve has two liquid outlet ports on the outside, the ball valve core and valve body of the existing T-type three-way ball valve usually rely on a single sealing surface. When the fluid pressure fluctuates or after long-term use, the liquid outlet on the back is prone to leakage due to wear of the sealing surface.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This utility model discloses a T-type three-way ball valve.

[0021] According to the appendix Figure 1-4 As shown, it includes valve body unit 1, which includes: Valve body 11; The valve core 14 is rotatably disposed inside the valve body 11. The bottom of the valve core 14 has an inlet 141, and the valve core 14 has an outlet 142 on one side and the back. A sealing unit 2 is provided on the valve body 11, and the sealing unit 2 is used to increase the sealing performance of the liquid outlet 142 located on the back side. The sealing unit 2 includes: A receiving groove 21 is formed on the inner wall of the valve body 11; The sealing block 22 is slidably disposed on the inner wall of the receiving groove 21, and the front of the sealing block 22 is inserted into the liquid outlet 142 located on the back. The lead screw 23 is rotatably mounted on the back of the sealing block 22, and the lead screw 23 is threadedly connected to the valve body 11.

[0022] By utilizing the inlet 141 at the bottom of the valve core 14 and the outlet 142 on the side and back of the valve core 14, the fluid path can be controlled by rotating the valve core 14, thereby facilitating the switching of the path. Furthermore, by rotating the lead screw 23, the sealing block 22 is pushed to move axially along the receiving groove 21, adjusting its sealing force on the back outlet 142. This can compensate for wear on the sealing surface or adapt to high-pressure conditions. Before switching the fluid path, the sealing block 22 can be moved away from the outlet 142 on the back of the valve core 14.

[0023] Furthermore, an inlet end 12 is installed at the bottom of the valve body 11, and an outlet end 13 is installed on both sides of the valve body 11.

[0024] Furthermore, a valve stem 15 is rotatably connected to the top of the valve body 11, the bottom end of the valve stem 15 is fixedly connected to the valve core 14, and the top end of the valve stem 15 extends upward through the valve body 11 and is fitted with a handle 17.

[0025] Furthermore, a positioning component 16 is provided between the valve stem 15 and the valve body 11 to limit the rotation angle of the valve stem 15.
