[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5 The utility model provides a technical solution: a three-way regulating valve that can be reversibly assembled, comprising a housing 1, with valve ports formed on both sides and the top of the housing 1, a front cover 2 fixedly mounted on one side of the housing 1 by bolts, a bracket 6 fixed on one side of the front cover 2 by bolts, an actuator 3 fixed on one side of the bracket 6 by bolts, a handle 12 rotatably mounted on one side of the actuator 3, and the actuator 3 is installed through the bracket 6;

[0021] The actuator 3 has a torque source inside. The coupling 7 is connected to the output shaft connected to the torque source. The other end of the coupling 7 is connected to the rotating shaft 5. The rotation direction of the rotating shaft 5 is adjusted by controlling the rotation of the internal torque source of the actuator 3.

[0022] A rotary valve 4 is fixed to one end of the rotating shaft 5 by a pin. The rotary valve 4 is located inside the housing 1. One end of the rotating shaft 5 passes through the front cover 2. The three valve ports are controlled to be open or closed by rotating the rotary valve 4. The direction of the rotary valve 4 is controlled by the rotating shaft 5.

[0023] A second O-ring 10 is installed between the rotating shaft 5 and the front cover 2. A sealing cover plate 8 is connected to one side of the front cover 2. The inner wall of the sealing cover plate 8 is penetrated by the rotating shaft 5. A first O-ring 9 is provided between the sealing cover plate 8 and the rotating shaft 5. The second O-ring 10 realizes the sealing between the rotating shaft 5 and the front cover 2, and the first O-ring 9 realizes the sealing function between the sealing cover plate 8 and the rotating shaft 5.

[0024] A third O-ring 11 is installed between the front cover 2 and the housing 1 to achieve a sealing effect between the front cover 2 and the housing 1;

[0025] A cooler 13 is connected to the valve port at one end of the shell 1, and a pipe with a temperature sensor 14 is connected to the valve port at the other end of the shell 1. The actuator 3 is electrically connected to a thermostat 15, and the thermostat 15 is electrically connected to the temperature sensor 14. The temperature sensor 14 collects the temperature signal of the liquid entering the shell 1 to adjust the working state of the thermostat 15 according to the temperature, and the operation of the actuator 3 is controlled by the thermostat 15.

[0026] Example 1: A coupling connects the actuator's output shaft to the shaft of a rotary valve (spool). The actuator receives a 4-20mA signal and, driven by an AC220V power supply, rotates the rotary valve. The rotational position is determined by the 4-20mA signal. A is the IN (OUT) port, B is the BYPASS port, and C is the COOLER port. Port A is normally open, port B opens at low temperatures, and port C opens at high temperatures. Figure 3 The middle position is when the temperature is low, at which point ports A and B are conducting. The same applies to other working states. Since ports A, B, C, and C can be interchanged during installation, there is no single installation method, making installation more flexible.
