[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention provides a graded temperature-controlled valve ring, comprising a heating tank 1; a circulation pipe 11 connected to the side wall of the heating tank 1; a circulation pump 16 installed in the middle of the circulation pipe 11; a multi-stage temperature-controlled heating assembly in the middle of the circulation pipe 11; a liquid replenishment assembly in the middle of the circulation pipe 11; an anti-backflow assembly in the middle of the circulation pipe 11 near the heating tank 1; a filter assembly in the middle of the circulation pipe 11; and a heat insulation assembly on the outer wall of the circulation pipe 11. During operation, the circulation pump 16 drives the circulation pipe 11 and the liquid in the heating tank 1 to circulate. The end of the circulation pipe 11 near the multi-stage temperature-controlled heating assembly is the inlet, and the other end is the outlet. The multi-stage temperature-controlled heating assembly monitors the temperature at the outlet of the heating tank 1. When the temperature is lower than the set value, [the valve ring is activated]. The multi-stage temperature-regulating heating assembly heats the liquid in the pipeline. When the liquid reaches the set value, part of the heating structure is turned off. The liquid replenishment assembly replenishes the liquid in the circulation pipeline 11 in a timely manner. When the return assembly is replenishing the liquid, the liquid that does not meet the temperature standard flows into the heating pool 1. The filtration assembly filters the liquid in the pipeline, and the insulation assembly keeps the liquid in the pipeline warm. Through the above structure, the multi-stage temperature-regulating heating assembly monitors the liquid in the heating pool 1 and heats the liquid in a timely manner, forming a graded temperature-regulating heating structure. This realizes the function of opening the heating structure in stages to heat the liquid, reducing the situation of drastic fluctuations in liquid temperature during heating, and reducing the situation of the liquid being too hot during heating and too cold after heating is stopped.

[0025] like Figures 1 to 4As shown, the multi-stage adjustable temperature control heating assembly includes a heating unit 12, an electric ball valve 13, a temperature controller 14, a temperature sensor 15, and branch pipes 17. Branch pipes 17 are fixedly connected to the middle of the circulation pipe 11. Multiple sets of branch pipes 17 are arranged in the middle of the circulation pipe 11. The heating unit 12 is located in the middle of the branch pipe 17. The electric ball valve 13 is installed in the middle of the branch pipe 17 near the heating unit 12. The electric ball valve 13 is connected to the temperature controller 14 via a signal line. The temperature sensor 15 is installed at the outlet end of the circulation pipe 11. The temperature sensor 15 is connected to the temperature controller 14 via a signal line. During operation, when the liquid circulates in the heating tank 1 and the circulation pipe 11, the temperature sensor 15 detects the temperature at the outlet end and transmits the signal to the temperature controller 14. The temperature controller 14 judges the liquid temperature and appropriately activates some of the heating units 12. 2. Electric ball valve 13 and heating unit 12 heat the liquid. After the electric ball valve 13 is opened, the liquid flows from the branch pipe 17 into the circulation pipe 11. After the temperature sensor 15 detects that the temperature has reached the specified value, the temperature controller 14 sends a signal to close part of the heating unit 12 and the electric ball valve 13, completing the multi-stage temperature control heating operation. Through the above structure, after the temperature sensor 15 measures the temperature of the liquid in the circulation pipe 11, the temperature controller 14 controls the opening of part of the heating unit 12 and the electric ball valve 13 to heat the liquid. This forms a multi-stage temperature control heating structure, realizing the function of controlling the temperature of the liquid in the circulation pipe 11. It solves the problem of the single heater not operating under full load when heating the liquid, improves the convenience of heating control, and reduces the situation of low-load operation of part of the heating unit 12 leading to decreased efficiency and losses.

[0026] like Figure 2 and Figure 4 As shown, the liquid replenishment assembly includes a liquid level sensor 2, a water replenishment valve 21, and a water replenishment pipe 22. The liquid level sensor 2 is installed on the inner wall of the heating tank 1. The liquid level sensor 2 is connected to the temperature controller 14 via a signal line. The water replenishment pipe 22 is fixedly connected to the middle of the circulation pipeline 11 away from the heating unit 12. A water pump is connected to the external water replenishment pipe 22. The water replenishment valve 21 is installed in the middle of the water replenishment pipe 22. The water replenishment valve 21 is connected to the temperature controller 14 via a signal line. During operation, when the liquid inside the heating tank 1 evaporates, the liquid level sensor 2 detects the liquid level in the heating tank 1. When the liquid level decreases, the liquid level sensor 2 sends a signal to the temperature controller 14, which then controls the water supply valve 21 to open. New liquid enters the circulation pipe 11 through the water supply pipe 22 to replenish the liquid in the heating tank 1. Through the above structure, the setting of opening the water supply valve 21 to fill the circulation pipe 11 with new liquid to replenish the liquid in the heating tank 1 forms a liquid replenishment structure, which realizes the function of replenishing the liquid in the device, reduces the situation where the liquid level in the heating tank 1 drops due to liquid evaporation, and improves the convenience of liquid replenishment.

[0027] like Figure 2 As shown, the filtration assembly includes a filter 3; the filter 3 is installed in the middle of the circulation pipeline 11 near the circulation pump 16; during operation, when the liquid circulates in the circulation pipeline 11, the liquid flows through the filter 3, and the filter 3 filters the liquid, removing impurities from the liquid; through the above structure, the filter 3 filters impurities from the liquid, forming the filtration structure of the device, realizing the function of filtering the circulating liquid, reducing the situation of impurities clogging the pipeline or other equipment, and improving the smoothness of the liquid flow in the device.

[0028] like Figure 5 As shown, the anti-backflow component includes a one-way valve 4; the one-way valve 4 is installed in the middle of the circulation pipeline 11 near the temperature sensor 15; during operation, when liquid in the heating tank 1 flows into the circulation pipeline 11, the one-way valve 4 is opened, and the liquid flows to the circulation pump 16. When liquid is replenished through the water supply pipe 22, the one-way valve 4 is closed by pressure; through the above structure, the one-way valve 4 sets the one-way control of the liquid flow direction in the circulation pipeline 11, forming a one-way liquid flow control structure, reducing the situation where unheated liquid flows back into the heating tank 1 when replenishing liquid, causing the temperature inside the heating tank 1 to drop.

[0029] like Figure 1 As shown, the insulation component includes insulation cotton 5; the insulation cotton 5 is sleeved on the outer wall of the circulation pipe 11; during operation, the insulation cotton 5 wraps around the outer wall of the circulation pipe 11 to insulate the circulation pipe 11; through the above structure, the insulation cotton 5 wraps around the circulation pipe 11 to insulate the circulation pipe 11, forming an insulation structure for the circulation pipe 11, reducing heat loss when the liquid flows in the circulation pipe 11.

[0030] like Figure 1 As shown, the circulation pipe 11 is a polyurethane insulated pipe; during operation, the circulation pipe 11 is a polyurethane insulated pipe to reduce the heat loss to the outside when the liquid flows in the pipe, thereby reducing energy consumption.

[0031] During operation, the circulating pump 16 drives the circulation pipe 11 and the liquid in the heating tank 1 to circulate. The end of the circulation pipe 11 closest to the multi-stage temperature-controlled heating component is the inlet, and the other end is the outlet. The multi-stage temperature-controlled heating component monitors the temperature at the outlet of the heating tank 1. When the temperature is lower than the set value, the multi-stage temperature-controlled heating component is activated to heat the liquid in the pipe. When the liquid reaches the set value, part of the heating structure is shut off, and the liquid replenishment component replenishes the liquid in the circulation pipe 11 in a timely manner. When the return component is placed to replenish the liquid, the temperature... Liquid that does not meet the required temperature flows into heating tank 1. The filtration assembly filters the liquid in the pipes, and the insulation assembly keeps the liquid in the pipes warm. While the liquid circulates in heating tank 1 and circulation pipe 11, temperature sensor 15 detects the temperature at the outlet and transmits the signal to temperature controller 14. Temperature controller 14 determines the liquid temperature and appropriately activates some heating units 12 and electric ball valve 13. Heating unit 12 heats the liquid. After opening electric ball valve 13, the liquid flows from branch pipe 17 into circulation pipe 11. After temperature sensor 15 detects that the temperature has reached the specified value, temperature controller 14 sends a signal to close some heating units 12 and electric ball valve 13, completing the multi-stage temperature control heating operation. When liquid evaporates inside heating tank 1, level sensor 2 detects the liquid level in heating tank 1. When the liquid level decreases, level sensor 2 sends a signal to temperature controller 14, which controls water supply valve 21 to open. New liquid enters circulation pipe 11 through water supply pipe 22 to replenish the liquid in heating tank 1. When the liquid circulates in the pipeline 11, it flows through the filter 3, which filters the liquid to remove impurities. When the liquid in the heating tank 1 flows into the circulation pipeline 11, the one-way valve 4 is opened, and the liquid flows to the circulation pump 16. When the liquid is replenished through the water supply pipe 22, the one-way valve 4 is closed by pressure. The insulation cotton 5 is wrapped around the outer wall of the circulation pipeline 11 to keep it warm. The circulation pipeline 11 is a polyurethane insulation pipe, which reduces the heat loss to the outside when the liquid flows in the pipeline and reduces energy consumption.
