For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] The present application is further described in detail below through drawings and examples.

[0031] Reference Figures 1 to 4 The embodiment of the present application provides a stop valve insulation sleeve device, including an insulation component 1, a heating component 2 fixedly installed inside the insulation component 1, the insulation component 1 includes an outer shell base 3, two outer shell rotating seats 4 rotatably arranged on the outer shell base 3, a rubber sealing tube 5 sleeved on the side of the heating component 2, and insulation cotton 12 between the two outer shell rotating seats 4 and the rubber sealing tube 5. The heating component 2 includes a sealing base 6, two sealing sheets 7 slidingly arranged on the upper side of the sealing base 6, a metal ring 8 rotatably arranged in the sealing base 6, a sliding ring 9 slidingly arranged on one side of the metal ring 8, and four heating rods 10 fixedly installed inside the sliding ring 9.

[0032] In this embodiment, when the heating rod 10 is turned on, the heating rod 10 heats the metal ring 8 and the stop valve. The heated metal ring 8 begins to thaw, and because the stop valve is thawed, the stop valve can work normally.

[0033] Reference Figures 1 to 4 In one aspect of the present embodiment, four hinges 11 are fixedly mounted on the shell base 3 and are respectively fixedly connected to the two shell rotating seats 4. The two rotating seats 4 are fixedly connected by bolts. The shell base 3 and the two shell rotating seats 4 are sleeved on the peripheral side of the thermal insulation cotton 12. The thermal insulation cotton 12 is sleeved on the peripheral side of the rubber sealing tube 5. The bottoms of the shell base 3, the thermal insulation cotton 12 and the rubber sealing tube 5 are all provided with circular holes 301.

[0034] In this embodiment, first, when the two outer shell rotating seats 4 need to be fixedly mounted on the sides of the thermal insulation cotton 12, the two outer shell rotating seats 4 are rotated at this time. The rotation of the two rotating seats 4 drives the hinge 11 to rotate. The installation of the hinge 11 facilitates the rotation coordination of the outer shell rotating seat 4 and the outer shell base 3.

[0035] Reference Figures 1 to 4 In one aspect of this embodiment, the upper surface of the sealing base 6 is provided with two recesses, the lower surfaces of the two sealing sheets 7 are provided with two sliding protrusions 701 respectively slidably fitted in the two recesses, and the bottom thread of the sealing base 6 is provided with a plug 13.

[0036] In this embodiment, the provision of the sliding protrusion 701 allows the sealing sheet 7 and the sealing base 6 to be installed together without being easily offset.

[0037] Reference Figures 1 to 4 In one aspect of this embodiment, two protrusions 601 are symmetrically provided at both ends of the sealing base 6 , and the metal ring 8 is located between the sealing base 6 and the two sealing sheets 7 .

[0038] In this embodiment, the sealing sheet 7 can seal the water stored in the sealing sheet 7 , so that the water inside the sealing sheet 7 is not likely to leak.

[0039] Reference Figures 1 to 4 In one aspect of this embodiment, the metal ring 8 is provided with four through holes for the heating rod 10 to slide, and the metal ring 8 is provided with a plurality of guide holes 801 for water to flow.

[0040] In this embodiment, when water is injected into the sealing plate 7, the water flows into the other end of the guide hole 801 through one end of the guide hole 801. The flowing water heats the metal ring 8, and the metal ring 8 heats the stop valve. The opening of the guide hole 801 facilitates the heating of the stop valve after the water flows.

[0041] Working principle: when it is necessary to heat the stop valve, first pick up the sliding ring 9, then turn on the heating rod 10, then align one end of the heating rod 10 with one end of the metal ring 8, then the metal ring 8 is heated by the heating rod 10, and then water is poured into the sealing base 6, then the water temperature in the sealing base 6 increases, then the metal ring 8 is rotated at this time, and the stop valve inside the metal ring 8 is heated during the rotation of the metal ring 8. Because the stop valve is heated, the frozen stop valve begins to thaw, and at the same time, the water inside the sealing base 6 also heats the stop valve, then the thawing speed of the stop valve is accelerated, and the metal ring 8 rotates around the stop valve, so that the stop valve is heated more evenly. When the heating of the stop valve is completed, the sliding ring 9 and the heating rod 10 are pushed to slide to the side away from the metal ring 8, and the metal ring 8 is separated from the heating rod 10 at this time, then the heating rod 10 is picked up to continue heating the next insulation sleeve.

[0042] When the stop valve needs to be insulated, first, two metal rings 8 are sleeved on both ends of the stop valve, and then the sealing base 6 and two sealing sheets 7 are sleeved on the surrounding sides of the metal rings 8, and then the rubber sealing tube 5 and the thermal insulation cotton 12 are sleeved on the surrounding sides of the stop valve in turn, and finally the outer shell base 3 and two outer shell rotating seats 4 are sleeved on the surrounding sides of the thermal insulation cotton 12. At this time, the thermal insulation cotton 12 is pressed by the rotating seat 4, and the thermal insulation cotton 12 now insulates the stop valve.
