The water source is added to the heating box 12 through the water inlet pipe 13, and then the electric heating tube 15 is started to generate heat to heat the water entering the heating box 12. After the water level in the heating box 12 continues to rise, it will enter the guide box 11 from the water outlet pipe 14, and then be discharged from the drain pipe 16 below. When the hot water flows in the guide box 11, it will contact the surface of the valve body 1 inside the guide box 11, thereby heating the valve body 1 through heat exchange. Through the above structure, the heating box 12, the electric heating tube 15 and the guide box 11 are set, and the valve body 1 can be heated by heating the external water source into the guide box 11 to reduce the situation where the valve body 1 is frozen when the temperature is low.

[0026] like Figure 2 As shown, the bottom of the drainage pipe 16 is fixedly connected to a water tank 2; the side wall of the guide box 11 is fixedly connected to a small water pump 21; the water tank 2 and the small water pump 21 are connected by a pipe; the output end of the small water pump 21 is connected to the water inlet pipe 13; the top of the water tank 2 is connected to a water injection pipe 22; when working, an external water source can be added to the water tank 2 from the water injection pipe 22, and then the small water pump 21 is started to pump the water in the water tank 2 into the heating box 12. When the water flow is discharged from the drainage pipe 16, it will enter the water tank 2 below again. At this time, the small water pump 21 is started to pump the water in the water tank 2 out and then send it into the heating box 12. At this time, the water flow can be circulated. Through the above structure, the water tank 2, the small water pump 21 and the water injection pipe 22 are set, which can heat the water while recycling the water flow to reduce the waste of water resources.

[0027] like Figure 3 and Figure 4 As shown, the inner wall of the heating box 12 is fixedly connected to a fixed frame 3; the fixed frame 3 is close to the side of the water inlet pipe 13; the inner wall of the fixed frame 3 is rotatably connected to a turbine 31; the turbine 31 is arranged corresponding to the water inlet pipe 13; during operation, when water flows into the heating box 12 from the water inlet pipe 13, the water flow will drive the turbine 31 to rotate when passing through the turbine 31, and at this time the turbine 31 will cause the water in the heating box 12 to generate a vortex, thereby stirring the water flow in the heating box 12. Through the above structure, the fixed frame 3 and the turbine 31 are set, and the water flow entering through the water inlet pipe 13 can drive the turbine 31 to rotate, thereby stirring the water in the heating box 12, so that the water and the electric heating tube 15 are in contact more evenly, thereby improving the heating effect of the water.

[0028] like Figure 4 As shown, a filter box 4 is installed in the middle of the water inlet pipe 13; a filter screen is provided inside the filter box 4; when working, before the water flows from the water inlet pipe 13 into the heating box 12, it will pass through the filter box 4. At this time, the filter screen installed in the filter box 4 will filter the water flow, thereby filtering out impurities such as mud and sand in the water flow. Through the above structure, the filter box 4 is set to cooperate with the internal filter screen to filter the water flow entering the heating box 12, so as to reduce the mud and sand impurities in the water from entering the heating box 12 and the guide box 11, causing dirt and corrosion to adhere to the surface of the electric heating tube 15 and the valve body 1.

[0029] like Figure 5As shown, the inner wall of the guide box 11 is fixedly connected with a riser 5; the riser 5 is aligned with the drain pipe 16; the top of the riser 5 is close to the top of the guide box 11; a plurality of water inlets 51 are provided on the side wall of the riser 5; the water inlet 51 is close to the top of the riser 5; during operation, when hot water enters the guide box 11, the water level in the guide box 11 will continue to rise. When the water level reaches the water inlet 51 at the top of the riser 5, it will enter the riser 5 from the water inlet 51 and then be discharged from the drain pipe 16. Through the above structure, the riser 5 and the water inlet 51 are set, so that hot water can be filled in the guide box 11. At this time, the valve body 1 can be immersed in hot water, which can improve the heating effect of the valve body 1 and reduce the situation where the heat exchange effect is incomplete due to the rapid flow of hot water.

[0030] like Figure 5 As shown, the insulation component includes an insulation layer 6; the insulation layer 6 is fixedly connected to the inner wall of the guide box 11; during operation, after hot water enters the guide box 11, the insulation layer 6 covers the inner wall of the guide box 11, and can insulate the interior. Through the above structure, the insulation layer 6 is set to insulate the interior of the guide box 11 to reduce the energy waste caused by heat loss to the outside.

[0031] like Figure 1 As shown, the side wall of the valve body 1 is sprayed with an anti-rust coating; through the above structure, the anti-rust coating sprayed on the surface of the valve body 1 can reduce the corrosion of water on the surface of the valve body 1, thereby increasing the service life of the valve body 1.

[0032] Working principle: After the valve body 1 is installed on the pipeline, when the weather is cold, the external water source is added to the heating box 12 through the water inlet pipe 13, and then the electric heating tube 15 is started to generate heat to heat the water entering the heating box 12. After the water level in the heating box 12 continues to rise, it will enter the guide box 11 from the outlet pipe 14, and then be discharged from the drain pipe 16 below. When the hot water flows in the guide box 11, it will contact the surface of the valve body 1 inside the guide box 11, thereby heating the valve body 1 through heat exchange. The external water source can be added to the water storage tank 2 from the water injection pipe 22, and then the small water pump 21 is started to pump the water in the water storage tank 2 into the heating box 12. When the water is discharged from the drain pipe 16, it will enter the water storage tank 2 below again. At this time, the small water pump 21 is started to pump the water in the water storage tank 2 The water is extracted and then sent into the heating box 12. At this time, the water flow can be circulated. When the water flow enters the heating box 12 from the water inlet pipe 13, the water flow will drive the turbine 31 to rotate when passing through the turbine 31. At this time, the turbine 31 will cause the water in the heating box 12 to generate a vortex, thereby stirring the water flow in the heating box 12. Before the water flow enters the heating box 12 from the water inlet pipe 13, it will pass through the filter box 4. At this time, the filter installed in the filter box 4 will filter the water flow, thereby filtering out impurities such as mud and sand in the water flow. When the hot water enters the diversion box 11, the water level in the diversion box 11 will continue to rise. When the water level reaches the water inlet 51 at the top of the riser 5, it will enter the riser 5 from the water inlet 51 and then be discharged from the drain pipe 16. After the hot water enters the diversion box 11, the insulation layer 6 covers the inner wall of the diversion box 11 to keep the interior warm.
