[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Embodiment 1: As Figures 1-4 shown, the present utility model provides a heat insulation component for a steam heat preservation pipe, which includes a heat insulation mechanism 1, and a main body mechanism 2 is fixedly installed on the top of the heat insulation mechanism 1;

[0027] The heat preservation mechanism 1 includes an operation panel 101. A first water tank 102 is fixedly installed at the top of the operation panel 101. A heater 103 is fixedly installed at the bottom of the inner wall of the first water tank 102. A temperature sensor 104 is fixedly installed on one side of the inner wall of the first water tank 102. A water cover 105 is arranged at the top of the first water tank 102. Two circulating water pipes 106 are fixedly inserted at the top of the water cover 105. Water pumps 107 are fixedly installed on the outer surfaces of the two circulating water pipes 106, and the bottoms of the two water pumps 107 are in contact with the top of the water cover 105. A heat preservation sleeve 108 is fixedly sleeved between the outer surfaces of the two circulating water pipes 106. A second water tank 109 is fixedly installed at the top of the operation panel 101, and the output ends of the two circulating water pipes 106 are both communicated with the inside of the second water tank 109. A connecting water pipe 110 is fixedly inserted on one side of the outer wall of the second water tank 109, and the output end of the connecting water pipe 110 is communicated with the inside of the first water tank 102. A control valve 111 is fixedly installed on the outer surface of the connecting water pipe 110.

[0028] The effect achieved by the entire Embodiment 1 is that when the steam heat preservation pipe is used in winter and needs to be transported over a long distance, a heat preservation mechanism 1 is arranged below the heat preservation pipe to maintain the heat preservation effect of the intermediate heat preservation pipe. First, the heater 103 in the first water tank 102 is started through an external controller to heat the water in the first water tank 102. Since a temperature sensor 104 is installed on one side of the inner wall of the first water tank 102 and the temperature sensor 104 is wirelessly connected to the external controller, the temperature sensor 104 detects the water temperature in the first water tank 102, and under the cooperation of the controller and the heater 103, the water temperature is controlled within the required range. Then, the two water pumps 107 are started, so that the water in the first water tank 102 flows along the two circulating water pipes 106 and passes through the heat preservation sleeve 108 installed below the heat preservation pipe. Through heat exchange, the heat in the water is transferred to the heat preservation pipe through the heat preservation sleeve 108 to heat the intermediate heat preservation pipe. Then, the water will flow into the second water tank 109 along the two circulating water pipes 106 instead of directly flowing into the first water tank 102, effectively avoiding the combination of the water that has provided heat and the original water from affecting the water temperature in the first water tank 102, thereby improving the heating effect on the heat preservation pipe. After a certain period of time, the control valve 111 is opened to make the water in the second water tank 109 return to the first water tank 102 and circulate in this way, which can avoid the situation of inappropriate heat preservation of the intermediate steam pipeline, improve the efficiency of heat preservation for medium transportation, and further improve the use effect of the heat preservation component of the steam heat preservation pipe.

[0029] Embodiment 2: As Figures 2-4As shown, the main body mechanism 2 includes an outer layer 201 with a thickness of 1 - 2 mm. The inner wall of the outer layer 201 is provided with a waterproof reflective layer 202 with a thickness of 0.5 - 1 mm. The inner wall of the waterproof reflective layer 202 is provided with a thermal insulation layer 203 with a thickness of 30 - 100 mm. The inner wall of the thermal insulation layer 203 is provided with a corrosion-resistant layer 204 with a thickness of 80 - 120 μm. The inner wall of the corrosion-resistant layer 204 is provided with an inner layer 205 with a thickness of 4 - 10 mm. The bottom of the outer layer 201 is fixedly connected to the top of the thermal insulation sleeve 108.

[0030] The effect achieved by the entire Embodiment 2 is that the steam thermal insulation pipe is the main body mechanism 2. Its outer layer 201 is composed of stainless steel material with a thickness of 1 - 2 mm, which can protect the thermal insulation material, prevent physical damage and the influence of the external environment, and at the same time provide a certain mechanical strength. Its waterproof reflective layer 202 is composed of composite aluminum foil cloth material with a thickness of 0.5 - 1 mm, which can prevent water penetration and protect the thermal insulation layer 203 to avoid the failure of the thermal insulation layer 203 due to moisture. Its thermal insulation layer 203 is composed of environmentally friendly high-temperature glass wool material with a thickness of 30 - 100 mm, which varies according to the pipe diameter and heat loss requirements. Its corrosion-resistant coating 204 is made of anti-corrosion coatings such as inorganic zinc-rich primer and polyurethane topcoat with a thickness of 80 - 120 μm, which can prevent the inner pipe from being corroded and oxidized and extend the service life of the pipe. Its inner layer 205 is composed of steel pipe material, responsible for transporting steam and bearing the pressure inside the pipe, so as to improve the use effect of the steam thermal insulation pipe.

[0031] Working principle: First, when the steam heat preservation pipe is used in winter and for long-distance transportation, an insulation sleeve 108 is installed under the steam heat preservation pipe in the middle. Then, two circulating water pipes 106 are fixedly inserted into the insulation sleeve 108. The input ends of the two circulating water pipes 106 are communicated with the inside of the first water tank 102, and the output ends are communicated with the inside of the second water tank 109. Then, the heater 103 in the first water tank 102 is started through an external controller, and with the cooperation of the temperature sensor 104, the water temperature in the first water tank 102 is controlled at an appropriate temperature. Then, the two water pumps 107 are turned on, so that the water in the first water tank 102 reaches the insulation sleeve 108 along the two circulating water pipes 106, and the heat is transferred to the steam heat preservation pipe through the insulation sleeve 108 to heat the steam heat preservation pipe. Then, the water will return to the second water tank 109 along the two circulating water pipes 106. After a certain period of time, the control valve 111 is opened, so that the water in the second water tank 109 returns to the first water tank 102 along the connecting water pipe 110, effectively avoiding the combination of the water that has delivered heat and the water with the original temperature, which affects the water temperature, thereby improving the heating effect of the heat preservation pipe. Secondly, through the functions of the waterproof reflective layer 202, the heat insulation layer 203 and the corrosion-resistant coating 204, the moisture penetration can be effectively prevented, the heat insulation layer 203 can be protected, and the heat insulation layer 203 can be prevented from failing due to dampness. The heat loss can be reduced, the temperature of the steam can be maintained, and the inner pipe can be prevented from being corroded and oxidized, prolonging the service life of the pipe, thereby improving the use effect of the heat preservation component of the steam heat preservation pipe.

[0032] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
