[0021] In order to deepen the understanding of the utility model, the utility model will be further described in combination with examples and drawings below, and the examples are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.

[0022] Please refer to Figures 1-5This utility model relates to a low-torque, high-efficiency three-way valve, comprising a valve body 6, a first through pipe 2 connected to the middle of the valve body 6, a second through pipe 3 connected to one side of the valve body 6, and a third through pipe 4 connected to the other side of the valve body 6. The first through pipe 2, the second through pipe 3, and the third through pipe 4 are all arranged perpendicularly to the valve body 6. The valve body 6 has a sealing port 9 and a water inlet 1, which are interconnected. An operating component 7 is rotatably installed in the sealing port 9. The operating component 7 includes an operating rod 8, a sealing column 10, a guide column 12, and a guide hole 11. The guide column 12 is rotatably installed in the sealing port 9, and the sealing column 10 is rotatably snapped into the sealing port 9. The sealing column 10 and the guide column 12 are fixed. The operating rod 8 is fixed to the sealing column 10. The guide hole 11 is located on one side of the guide column 12. The water inlet 1 is connected to the third through pipe 4 and the second through pipe 3 in sequence after the operating component 7 rotates.

[0023] Specifically, the valve body 6, as the main structure of the three-way valve, is used to support and connect the various pipes of the valve; the first pipe 2, the second pipe 3, and the third pipe 4 are all connected to the inlet 1 without the operating component 7; the sealing port 9 has a hole with a slightly larger radius for engaging the guide post 12; one end of the guide hole 11 is located on the cylindrical top surface of the guide post 12, and the other end of the guide hole 11 is located on the side of the guide post 12; when this valve is in use, the water flow is constant through the first pipe 2, and the opening and closing of the second pipe 3 and the third pipe 4 are controlled by the operating component 7, such as... Figure 5 As shown, when the through hole 11 corresponds to the second through pipe 3, the second through pipe 3 is connected to the inlet 1. When the through hole 11 corresponds to the third through pipe 4, the third through pipe 4 is connected to the inlet 1. When the through hole 11 is facing upward, only the first through pipe 2 is connected to the inlet 1. At this time, the water pressure acts on the through column 12 and is then transmitted to the sealing column 10. With this design, the friction force during rotation is concentrated at the sealing column 10 and the sealing port 9, which reduces the friction force and the operating torque of the operating component 7. This design also allows lubricating oil to be added between the sealing column 10 and the sealing port 9 to further reduce the friction force. However, ordinary three-way valves cannot add lubricating oil due to their structure.

[0024] For ease of installation, the lower sides of the first connecting pipe 2, the second connecting pipe 3, and the third connecting pipe 4 are all equipped with installation plugs 5. To achieve a better sealing effect, the radius of the sealing column 10 is twice that of the conducting column 12. The first connecting pipe 2, the second connecting pipe 3, and the third connecting pipe 4 are arranged parallel to each other. Lubricating oil is provided at the snap-fit ​​point between the sealing column 10 and the sealing port 9 to provide additional lubrication, while increasing the sealing performance, reducing friction, and further reducing the operating torque. The lubricating oil can be PTFE lubricating oil. The sealing column 10 is made of ceramic, the valve body 6 is made of aluminum alloy, and the inner side of the sealing port 9 is made of ceramic. The use of these materials further reduces friction and reduces the torque required when operating the components 7.

[0025] Finally, it is pointed out that the above embodiments are only to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The present application should be covered in the scope of the claims.
