[0002] A three-way valve is a valve device with one inlet and two outlets. It can control the flow direction of liquid in the liquid delivery pipeline and is an important control component in the liquid delivery pipeline.

[0003] The existing three-way valve only has the function of regulating flow direction. In actual use, the connection between different channels can be achieved by adjusting the three-way valve, but the opening of the two outlets cannot be adjusted separately according to the actual use needs of the user, and the use needs of different users cannot be met. The scope of application is small. At present, in actual use, when the user needs to adjust the opening of the two outlets separately, a new flow control valve needs to be introduced and used in combination with the existing three-way valve, which will increase the use cost and subsequent maintenance cost. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a three-way valve to achieve

[0005] The purpose is to expand the scope of application and reduce the subsequent use cost and maintenance cost.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a three-way valve, including a valve housing, a water inlet at the bottom of the valve housing, a first water outlet and a second water outlet are staggered and relatively arranged on the side of the valve housing, the setting height of the first water outlet is smaller than the setting height of the second water outlet, a valve core assembly is rotatably arranged in the valve housing, and the valve stem for driving the valve core assembly to rotate is fixedly arranged on the top of the valve core assembly, and the valve stem is rotatably arranged on the valve housing and extends to the outside of the valve housing.

[0007] As a limitation of the present utility model, the valve core assembly includes a first valve core and a second valve core rotatably arranged on the top of the first valve core; the valve stem is fixed on the top of the second valve core; a first limit block is fixedly provided at the upper end of the inner side of the first valve core, and a second limit block is fixedly provided at the lower end of the inner side of the second valve core, and the bottom of the first limit block and the bottom of the second limit block are located on the same horizontal plane.

[0008] As a further limitation of the present invention, a sealing sleeve is fixedly provided on the outer side of the valve core assembly and the sealing sleeve matches the overall shape and size of the valve core assembly.

[0009] As a further limitation of the present invention, the sealing sleeve is made of silicone rubber material.

[0010] As a further limitation of the present invention, a mounting seat is fixedly provided on the valve housing, a valve actuator for driving the valve stem to rotate is fixedly installed on the mounting seat, and a power output end of the valve actuator is fixedly connected to the valve stem.

[0011] As another limitation of the present utility model, the water inlet is connected to a water inlet pipe, the first water outlet is connected to a first water outlet pipe, and the second water outlet is connected to a second water outlet pipe.

[0012] As a further limitation of the present utility model, the water inlet pipe is connected to the water inlet pipe and is provided with a water inlet pipe adapter joint with internal threads.

[0013] As a further limitation of the present utility model, the first water outlet pipe is connected to a first pagoda joint, and the second water outlet pipe is connected to a second pagoda joint.

[0015] (1) The utility model adopts a structure that combines a valve housing, a valve core assembly, and a valve stem, wherein the valve housing has a water inlet, a first water outlet, and a second water outlet. By controlling the rotation of the valve stem, the valve core assembly can independently adjust the opening of the first water outlet and the second water outlet, which can meet the use needs of more users and effectively expand the scope of application. In addition, when used, the utility model does not need to be used in combination with a flow control valve, that is, the opening of the first water outlet and the second water outlet can be independently adjusted, which can effectively reduce the use cost and reduce the subsequent maintenance cost.

[0016] (2) The utility model has a simple structure and is easy to use. The valve core assembly includes a first valve core and a second valve core. When the utility model is in use, when it is necessary to adjust the opening of the first water outlet, the valve stem rotates to drive the second valve core to rotate. When the second valve core rotates to drive the second limit block to rotate until it contacts the first limit block, the valve stem continues to rotate to adjust the opening of the first water outlet. After adjusting the opening of the first water outlet, it is only necessary to rotate the valve stem in the opposite direction. At this time, the second limit block is separated from the first limit block, so that the opening of the second water outlet can be adjusted separately.

[0017] (3) The utility model provides a sealing sleeve made of silicone rubber material on the outside of the valve core assembly, which can ensure the sealing of the valve core assembly structure and prevent water from flowing out of the valve housing, thereby effectively improving the reliability and practicality of the structure of the utility model.

[0018] (4) The utility model is provided with a valve actuator, which can drive the valve stem to rotate and thereby adjust the opening of the first water outlet and the opening of the second water outlet, which can effectively improve the practicality of the utility model.

[0019] (5) The utility model is provided with a water inlet pipe adapter joint with an internal thread, a first pagoda joint and a second pagoda joint, which can facilitate the connection with the external pipeline and effectively improve the convenience of operation of the utility model.

[0020] In summary, the utility model has a simple and reasonable structure, is easy to use, and has strong usability. By controlling the rotation of the valve stem, the valve core assembly can independently adjust the opening of the first water outlet and the second water outlet, which can meet the use needs of more users. While expanding the scope of application, it can also effectively reduce the use cost and the subsequent maintenance cost. The utility model is suitable for installation in a liquid delivery pipeline to achieve control of the flow direction and flow of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS
