[0008] Furthermore, four sets of springs are fixedly connected to the ends of pipe openings one, two, three, and four near the rotating barrel, respectively, and four sets of polytetrafluoroethylene rings are fixedly connected to the ends of the four sets of springs near the rotating barrel, with all four sets of polytetrafluoroethylene rings abutting against the rotating barrel.

[0009] Furthermore, a magnet is fixedly mounted on the top of the rotating shaft, and a Hall sensor is fixedly mounted on the top of the inner cavity of the upper cover in conjunction with the magnet.

[0010] Furthermore, an interface is fixedly provided on one side of the top cover, and several terminals are fixedly connected to the side of the interface near the top cover. The terminals are respectively connected to the Hall sensor and the motor.

[0011] Furthermore, there are five sets of terminals, three of which are connected to Hall sensors, and the other two are connected to the motor.

[0012] Furthermore, the upper part of the valve body is equipped with a shaft sealing assembly to seal between the shaft and the valve body, and the shaft sealing assembly is sleeved on the middle of the outer surface of the shaft.

[0018] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0019] Example 1 like Figure 1-5 As shown, the thermal control valve includes a valve body 1, a top cover 2 fixedly mounted on the top of the valve body 1, several pipe openings fixedly mounted on the valve body 1 at intervals, a rotating barrel 3 rotatably mounted inside the valve body 1, several through holes being opened through the valve body 1 and the rotating barrel 3 respectively, a rotating shaft 4 rotatably mounted on the top of the valve body 1, and the bottom of the rotating shaft 4 is fixedly connected to the rotating barrel 3, the top of the rotating shaft 4 penetrates the valve body 1 and extends into the top cover 2, a gear 5 is fixedly mounted on the top of the outer surface of the rotating shaft 4, a worm gear 6 is meshed with one side of the gear 5, and a motor 7 is meshed with the end of the worm gear 6 away from the gear 5, and the gear 5, worm gear 6 and motor 7 are all mounted inside the top cover 2.

[0020] During operation, the starter motor 7 drives the worm gear 6 to rotate, which in turn drives the gear 5 to rotate. The rotation of the gear 5 drives the rotating shaft 4 to rotate, which in turn drives the rotating barrel 3 to rotate. The rotation of the rotating barrel 3 drives several through holes to rotate, thereby controlling the connection status of several through holes and several pipe openings. When several through holes and several pipe openings are connected, the thermal control valve can input coolant into each component through several pipe openings. When several through holes and several pipe openings are not connected, the thermal control valve is in a closed state.

[0021] Several pipe openings include pipe opening 1 (8), pipe opening 2 (9), pipe opening 3 (10), and pipe opening 4 (11). Several through holes are respectively opened on the valve body 1 and the rotating barrel 3 to match pipe opening 1 (8), pipe opening 2 (9), pipe opening 3 (10), and pipe opening 4 (11).

[0022] With the above settings, the number of through holes is greater than four, and the number of through holes connecting pipe port 1 8, pipe port 2 9, pipe port 3 10 and pipe port 4 11 is not less than one. Pipe port 1 8, pipe port 2 9, pipe port 3 10 and pipe port 4 11 cannot be connected to their respective through holes at the same time.

[0023] The rotating barrel 3 is sealed to the pipe openings 8, 9, 10, and 11 by a polytetrafluoroethylene ring 12 and a spring 13.

[0024] Four sets of springs 13 are fixedly connected to the ends of pipe opening 1 8, pipe opening 2 9, pipe opening 3 10 and pipe opening 4 11 near the rotating barrel 3, respectively. Four sets of polytetrafluoroethylene rings 12 are fixedly connected to the ends of the four sets of springs 13 near the rotating barrel 3, and all four sets of polytetrafluoroethylene rings 12 are in contact with the rotating barrel 3.

[0025] With the above configuration, the PTFE ring 12 abuts against the rotating barrel 3 under the pressure of the spring 13 and the first, second, third, and fourth ports 8, 9, 10, and 11. Furthermore, the inner diameter of the PTFE ring 12 is compatible with the diameter of the through hole, ensuring that the rotating barrel 3 and the first, second, third, and fourth ports 8, 9, 10, and 11 can maintain a seal when the thermal control valve is in the connected or closed state.

[0026] A magnet 14 is fixedly installed at the top of the rotating shaft 4, and a Hall sensor 15 is fixedly installed at the top of the inner cavity of the upper cover 2 in conjunction with the magnet 14.

[0027] With the above setup, the magnet 14 and the rotating shaft 4 are fixedly connected. The magnet 14 can rotate with the rotating shaft 4, thereby generating periodic changes in the direction and intensity of the magnetic field. By setting the Hall sensor 15, the magnetic field changes can be detected and converted into electrical signals, realizing real-time detection of the rotation speed of the rotating shaft 4.

[0028] An interface 17 is fixedly provided on one side of the upper cover 2. Several terminals 18 are fixedly connected to the side of the interface 17 near the upper cover 2. The terminals 18 are respectively connected to the Hall sensor 15 and the motor 7.

[0029] The terminal 18 is provided in five sets, of which three sets of terminal 18 are connected to the Hall sensor 15, and the other two sets of terminal 18 are connected to the motor 7.

[0030] With the above settings, an external controller is connected to interface 17. The controller can process the electrical signal of Hall sensor 15 and read the rotation speed of shaft 4. It can also adjust the rotation speed of shaft 4 by adjusting motor 7.

[0031] A shaft sealing assembly 19 is provided on the upper part of the valve body 1 in conjunction with the rotating shaft 4, which is used to seal between the rotating shaft 4 and the valve body 1, and the shaft sealing assembly 19 is sleeved on the middle of the outer surface of the rotating shaft 4.

[0032] With the above settings, the shaft sealing assembly 19 can seal the space between the rotating shaft 4 and the valve body 1, and can limit the position of the rotating shaft 4, thus ensuring the stability of the device during operation.

[0033] The output end of motor 7 is set upward, and the output end of motor 7 is fixedly connected to motor worm 16, which meshes with worm 6.

[0034] With the above settings, during operation, the starter motor 7 drives the motor worm gear 16 to rotate, the motor worm gear 16 rotates and drives the worm gear 6 to rotate, which in turn drives the gear 5 and the rotating shaft 4 to rotate, thereby realizing the rotation of the rotating barrel 3.

[0035] The valve body 1 is made of die-cast aluminum. The top cover 2, motor 7, pipe port 1 8, pipe port 2 9, pipe port 3 10 and pipe port 4 11 are all fixedly connected to the valve body 1 by several bolts. Several bolt holes 20 are provided at intervals at the bottom of the valve body 1.

[0036] With the above-mentioned design, gear 5 is machined from a single piece of metal, which improves the strength and extends the service life of gear 5; valve body 1 is made of die-cast aluminum, which also increases the service life of valve body 1; valve body 1 is fixedly connected to the top cover 2, motor 7, port 1 8, port 2 9, port 3 10, and port 4 11 by several bolts, which facilitates the disassembly of the top cover 2, motor 7, port 1 8, port 2 9, port 3 10, and port 4 11, improving the efficiency of replacing or repairing the above components and saving costs; several bolt holes 20 are provided at intervals at the bottom of valve body 1, which can be used to fix valve body 1 to other equipment.
