At present, most thermal insulation materials on the market use traditional insulation materials such as aluminum silicate wool and glass wool, but they have defects such as high thermal conductivity, many seams, poor waterproofness, and short service life. Therefore, there is a need for a composite structure, one-piece, detachable valve insulation cover that can effectively overcome the above problems. Utility Model Content

[0004] The object of the present invention is achieved through the following technical solutions.

[0005] The utility model discloses a composite structure integrated detachable valve insulation cover, which comprises an aluminum silicate wool felt insulation layer, an aerogel felt insulation layer, an outer protective layer insulation cover and an anti-slip fixing piece.

[0006] The anti-slip fixing piece is fixed on the inner surface of the outer protective layer insulation sleeve, penetrates the aerogel felt insulation layer and the aluminum silicate wool felt insulation layer, and forms a whole, thereby preventing the aerogel insulation layer and the aluminum silicate wool felt insulation layer from falling off; the aluminum silicate wool felt insulation layer (1), the aerogel felt insulation layer, the outer protective layer insulation sleeve and the anti-slip fixing piece are integrally formed, and are directly covered on the valve body when the valve is insulated.

[0007] Preferably, the outer surface of the valve uses an aluminum silicate wool felt insulation layer as the inner layer, and an aerogel felt insulation layer is tightly attached to the outside of the aluminum silicate wool felt insulation layer to reduce the volume of the insulation sleeve and enhance the insulation effect.

[0008] Further preferably, the aluminum silicate wool felt insulation layer is selected with classification temperature No. 1, its density is ≥110kg / m3, and its thickness is 50mm, and it itself has good fire resistance.

[0009] Preferably, the aerogel felt insulation layer is made of a glass fiber-based aerogel material with a thickness of 40 mm. A hydrophobic agent is added to the material, which is tightly attached to the outside of the aluminum silicate wool felt insulation layer. The aerogel material is an inorganic product and has A1-level fire resistance, which meets the fire resistance requirements of various types of pipeline valves.

[0010] Further preferably, the aerogel felt insulation layer is made of a glass fiber-based aerogel material, the thermal conductivity of which is only 0.016 to 0.020 W / mK under normal conditions, and the insulation thickness is much smaller than that of traditional rock wool insulation materials. A hydrophobic agent is added to the aerogel felt insulation layer material, and the hydrophobic effect reaches 99.99%, eliminating the insulation failure caused by the intrusion of external water vapor.

[0011] Preferably, the composite structure integrated detachable valve insulation cover disclosed in the present invention also includes a silicone-coated glass fiber cloth with an adjustable quick buckle as the outer protective layer insulation cover, which has a thickness of 0.8 mm, is resistant to high temperatures and has A1 grade fire resistance.

[0012] Further preferably, the anti-slip fixing part is a plastic insulation nail with a diameter of 6 mm. The bottom disc is bonded to the inner side of the outer protective layer insulation sleeve and is used to fix the aluminum silicate wool felt insulation layer and the aerogel felt insulation layer to prevent the insulation layer from slipping.

[0013] Beneficial effects:

[0014] 1. In the prior art, direct use of aerogel felt for insulation inevitably creates cavities, resulting in poor insulation. The present invention discloses a composite, integrated, removable valve insulation sleeve comprising an aluminum silicate wool felt insulation layer, an aerogel felt insulation layer, an outer protective insulation sleeve, and anti-slip fasteners. The aluminum silicate wool felt insulation layer used as the inner layer fits tightly against the valve's exterior surface, preventing loose insulation and poor insulation performance due to irregular shapes on the valve's exterior.

[0015] 2. The utility model discloses a composite structure integrated detachable valve insulation cover, which is tightly attached to the aerogel felt insulation layer on the outside of the aluminum silicate wool felt insulation layer to reduce the volume of the insulation cover and enhance the insulation effect.

[0016] 3. The utility model discloses a composite structure integrated detachable valve insulation cover, in which the anti-slip fixing parts (insulation nails) are fixed on the inner surface of the outer protective layer insulation cover, penetrating the aerogel felt insulation layer and the aluminum silicate wool felt insulation layer to form a whole, thereby preventing the aerogel insulation layer and the aluminum silicate wool felt insulation layer from falling off. When insulating the valve, it is directly installed on the outside of the valve body to achieve valve insulation. It can be quickly disassembled during maintenance to improve the utilization rate of the insulation material; it can be quickly installed at the end of maintenance to reduce labor intensity, improve labor efficiency, and shorten the construction period. The utility model is not only convenient to disassemble and easy to install, but also has the advantages of low cost, portability, repeated use, long service life, and environmental protection and pollution-free.

[0021] The outer surface of the valve uses an aluminum silicate wool felt insulation layer 1 as the inner layer, and an aerogel felt insulation layer 2 is tightly attached to the outside of the aluminum silicate wool felt insulation layer 1 to reduce the volume of the insulation sleeve and enhance the insulation effect.

[0022] The aluminum silicate wool felt insulation layer 1 is selected from the classification temperature No. 1, and its density is ≥110kg / m 3 , with a thickness of 50mm, which has good fire resistance.

A hydrophobic agent is added to the material, and it is tightly attached to the outer side of the aluminum silicate wool felt insulation layer 1. The aerogel material is an inorganic material and has A1-level fire resistance, which meets the fire resistance requirements of various types of pipeline valves.

[0024] The aerogel felt insulation layer 2 is made of a glass fiber-based aerogel material, and its thermal conductivity is only 0.016 to 0.020 W / mK under normal conditions. The insulation thickness is much smaller than that of traditional rock wool insulation materials. In addition, a hydrophobic agent is added to the aerogel felt insulation layer 2 material, and the hydrophobic effect reaches 99.99%, eliminating the insulation failure caused by the intrusion of external water vapor.

[0025] The silicone-coated glass fiber cloth with an adjustable quick buckle is used as the outer protective layer insulation cover 3, has a thickness of 0.8 mm, is resistant to high temperatures and has A1 grade fire resistance.

[0026] The anti-slip fixing part 4 is made of plastic insulation nails with a diameter of 6 mm. The bottom disc is bonded to the inner side of the outer protective layer insulation sleeve 3 and is used to fix the aluminum silicate wool felt insulation layer 1 and the aerogel felt insulation layer 2 to prevent the insulation layer from slipping.

[0027] The working method of the composite structure integrated detachable valve insulation cover disclosed in the utility model is as follows:

[0028] When installing the composite, integrated, removable valve insulation cover disclosed in this utility model, place the cover on a clean, flat work mat to prevent dragging and scratching the cover surface. Select a valve insulation cover that matches the valve's shape, wrap it around the outside of the valve, and secure it with the adjustable quick-release buckle on the outer protective insulation cover 3. Reverse the steps for disassembly, making it easy to disassemble and install.
