[0033] Please see Figure 1-6 The present invention provides a technical solution:

[0034] A smart valve and its usage method include a smart valve housing 1, an inlet pipe 2, and an outlet pipe 3. A switch 4 is fixedly connected to the right front end of the smart valve housing 1.

A first fixing post 6 is provided on the upper right side of the smart valve housing 1. A cylindrical housing 22 is fixedly connected to the left end of the first fixing post 6. A temperature control unit is provided on the inner right side of the cylindrical housing 22. The temperature control unit can automatically adjust the heating temperature of the smart valve for the flowing fluid according to the temperature change. In one embodiment, the temperature control unit can be a thermally expandable and contractible material 33. A movable limiting post 30 is slidably connected to the inner side of the left end of the cylindrical shell 22. A movable conductive rod 23 is fixedly connected to the left end of the movable limiting post 30. A limiting groove 31 is opened on the upper side of the left end of the movable conductive rod 23.

Several electric heating wires 20 are provided on the inner side of the lower end of the intelligent valve shell 1.

[0035] A heat insulation shell 34 is fixedly connected to the inner side of the upper end of the intelligent valve housing 1. An electronic valve 24 is fixedly connected to the middle of the heat insulation shell 34. A movable conductive rod 23 is located at the rear side of the upper end of the heat insulation shell 34. The upper and lower ends of the intelligent valve housing 1 are respectively provided with an outlet 19 and an inlet 18. The upper end of the intelligent valve housing 1 is fixedly connected to the outlet pipe 3 through the outlet 19, and the lower end of the intelligent valve housing 1 is fixedly connected to the inlet pipe 2 through the inlet 18. An outdoor temperature detector 7 is provided at the upper end of the intelligent valve housing 1. Specifically, the outdoor temperature detector 7 can be a common temperature sensor. An electric heating wire 20 is provided on the inner side of the lower end of the intelligent valve housing 1. The lower end of the electric heating wire 20 is fixedly connected to the inner wall of the lower end face of the intelligent valve housing 1. The upper end of the electric heating wire 20 is fixedly connected to the inner wall of the lower end face of the intelligent valve housing 1.

The distance between the left and right ends of the partition 21 and the inner wall of the intelligent valve shell 1 is 2cm, which facilitates the heating of the water source entering the inlet 18 by the multiple electric heating wires 20 during actual use. Moreover, the partition 21 allows the water source to flow through the motor heating wire 20 for a longer time, which can improve the heating effect. The center points of the outlet 19 and the inlet 18 at the upper and lower ends of the intelligent valve shell 1 are set on the same vertical line. A connecting hole is opened in the middle of the heat insulation shell 34. The connecting hole between the inlet 18, the outlet 19 and the heat insulation shell 34 is connected to the inlet 18, the outlet 19 and the heat insulation shell 34. The through-hole is designed for easy water supply. The bottom of the inlet pipe 2 is spirally connected to a connecting housing 8. The vertical cross-section of the connecting housing 8 is T-shaped, and the interior of the connecting housing 8 is hollow. A limiting ring plate 15 is fixedly connected to the inner side of the bottom of the connecting housing 8. A sealing gasket 17 is fixedly connected to the inner side of the lower end of the limiting ring plate 15 through a limiting groove 16.

The second clamp 12 is fixedly connected by standard bolts through the second fixing holes 13 opened at both ends of the second clamp 12. There are two fixing blocks 14 in total. The fixing blocks 14 are set horizontally with the center point of the first clamp 11 as the center point. In actual use, this can improve the convenience of the overall installation process and the stability after installation. The right end of the intelligent valve shell 1 is fixedly connected to the power cord 5. The intelligent valve shell 1 is made of insulating material. The power cord 5 is electrically connected to the first conductive block 25, the second conductive block 26, the third conductive block 27, the electric heating wire 20, and the movable conductive rod 23. This allows the number of electric heating wires 20 to be operated to be controlled by the number of first conductive blocks 5 and second conductive blocks 26 connected.

[0036] In another embodiment of this invention, the thermal expansion material in the temperature control unit can be replaced by other forms, such as using the extension and contraction length of the electric telescopic rod at different temperatures to control the number of working electric heating wires. Specifically, a miniature electric telescopic rod is fixedly connected to the inner right side of the cylindrical shell 22. The left end (i.e., the telescopic end) of the miniature electric telescopic rod is fixedly connected to the right end of the movable limiting post 30. The outdoor temperature detector 7 has a built-in controller, and the outdoor temperature detector 7 and the miniature electric telescopic rod are electrically connected.

A third conductive block 27 is slidably connected to the inner side of the limiting groove 31, which makes the adjustment of the number of working electric heating wires 20 more precise.

[0037] The method for heating fluids using the aforementioned intelligent valve includes the following steps:

[0038] Step 1: Install the smart valve: Install the smart switch on the external water pipe through the connecting housing 8 at the lower end of the inlet pipe 2. During the installation process: First, install the first clamp 11 and the second clamp 12 near the outlet of the external water pipe (use standard bolts for fixing). After installation, fix the connecting housing 8 and the external water pipe through the limiting ring plate 15 (use fixing screws 10 through the first fixing hole 9 and fixing block 14 for connection and fixing during the connection process). During the connection process, pay attention to the sealing gasket 17 fixed at the upper end of the external water pipe and the inner side of the limiting ring plate 15. After installation, it can be used.

[0039] Step 2: Debugging and testing: Connect the power cord 5 and the external power supply. After powering on, control the electronic valve 24 through switch 4. Then, use a thermometer to measure the temperature of the water flowing out of the outlet pipe 3. Compare the measured data with the actual temperature. If the comparison is within a reasonable range, it can be put into use.

[0040] Intelligent valve operation process: The thermal expansion and contraction material 33 can control the movement of the conductive rod 23 left and right according to the external temperature. During the left and right movement of the conductive rod 23, the first conductive block 25 and the second conductive block 26 are misaligned. At this time, the electric heating wire 20 can be controlled to heat the water source entering the inlet 18 (in actual use, the higher the external temperature, the fewer the number of the first conductive block 25 and the second conductive block 26 connected together, and the fewer the number of electric heating wires 20 are engaged). This setting can adjust the heating effect according to the external temperature in actual use. It has good practical value in actual use and is worth promoting and using widely.
