[0002] Valve, also called stop valve, is one of the most widely used valves. It is mainly used in various systems such as petroleum, chemical, metallurgy, and pharmaceuticals. During the transportation process, in order to ensure that the internal medium will not solidify due to the external temperature, an insulation sleeve needs to be installed on the outside of the stop valve.

[0003] Patent publication number "CN220268468U" discloses "a stop valve insulation sleeve device, which relates to the technical field of stop valve insulation sleeves. In order to solve the problem that the existing insulation sleeves are soft, have low strength, and are easily affected by the external environment and cause their outer skin to tear, the second insulation sleeve is composed of two left and right second combination sleeves, a stainless steel outer shell, which is arranged on the outer walls of the first combination sleeve and the second combination sleeve, a nano aerogel felt is arranged inside the stainless steel outer shell, and a glass fiber layer is arranged inside the nano aerogel felt."

[0004] In view of the above-mentioned related problems, the existing valve protection sleeve lacks the function of heating the valve, so that the valve is prone to freezing in a low-temperature environment, and the valve cannot be used in a low-temperature state.

[0005] Therefore, the utility model provides a detachable valve insulation sleeve to solve the above problems. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a detachable valve insulation cover, which solves the problem that the above-mentioned existing valves are prone to freezing in low temperature environments, thereby causing the valves to be unusable.

[0014] By adopting the above technical solution, the heat conducting sheet can be arranged to transfer heat, so that the valve is not easy to freeze after being heated.

[0015] Furthermore, one end of the heating belt is a spiral structure, the other end of the heating belt is located outside the heating component, and the heat conductive sheet is sleeved on the circumference of the valve.

[0016] By adopting the above technical solution and installing a heating belt, the valve can be heated, so that the valve is not easily frozen after being heated.

[0017] Furthermore, guide grooves for the flow and gathering of condensed water are provided on the inner walls of the three heat-conducting plates, a first through hole is provided at the bottom of one of the heat-conducting plates for the outflow of condensed water, and a second through hole is provided at the bottom of the two outer shells, the thermal insulation cotton, the compression plate and one of the rubber plates for the outflow of condensed water.

[0032] In this embodiment, when the annular clamp 4 rotates, the annular clamp 4 presses the outer shell 3. After the outer shell 3 is pressed, the outer shell 3 clamps and fixes the heating component 2.
