For valves, which are complex structures with many irregularly shaped parts, the installation and disassembly process requires a lot of manpower and time. Moreover, when the operating space is limited, the construction is difficult. For example, during the maintenance of chemical plants, the removal and reinstallation of valve insulation often delays the maintenance progress. Therefore, this application proposes a detachable all-metal valve insulation device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This embodiment provides a detachable all-metal casing valve insulation device, the structural schematic diagram of which is shown below. Figures 1-7As shown, the device includes an insulation shell 3, which is a cylindrical structure. The insulation shell 3 is symmetrically divided into two parts along the axial direction. Each part of the insulation shell 3 has a second flange 21 hinged to it on one side, and a first flange 5 on the other side. A connector 6 is provided between the pair of first flanges 5. Both ends of the insulation shell 3 have pipe fitting holes 7. A valve stem fitting hole 9 is provided on the side of each insulation shell 3 facing the first flange 5. A boss 4 is provided on the side of each insulation shell 3 facing the first flange 5, and the valve stem fitting hole 9 is located on the boss 4. Through this structure, the two insulation shells 3 are hinged and rotated to open and close on the valve body 1 via the second flange 21, connecting to the conveying pipe 2 of the valve body 1. The control components of the valve body 1 are placed inside the boss 4, passing through the pipe adapter holes 7 at both ends of the insulation shell 3. The valve stem of the valve body 1 passes through the valve stem adapter hole 9 on the boss 4. The two first edge plates 5 are connected by the connector 6, and the two insulation shells 3 are connected and closed to fit on the valve body 1. The insulation performance provided by the insulation shell 3 is used to achieve the purpose of heat preservation of the valve body 1, so as to avoid heat loss at the valve body 1 or the impact of temperature changes caused by the external environment on the utilization efficiency of the conveying medium, the safety of equipment operation, and product quality. The whole adopts the method of rotating and opening and closing the two insulation shells 3 on the valve body 1, which is convenient for disassembly and assembly, can be reused, and the installation and disassembly process does not require a lot of manpower and time, which is conducive to the maintenance of the valve body 1.

[0026] In this embodiment, an insulation layer 13 is provided on the inner wall of the insulation shell 3. The insulation layer 13 is made of one of polyurethane foam, phenolic foam, or polystyrene foam. An insulation interlayer 12 is provided inside the shell wall of the insulation shell 3. The insulation interlayer 12 is made of one of rock wool, glass wool, or aerogel felt. The excellent insulation performance provided by the insulation layer 13 on the inner wall of the insulation shell 3 and the insulation interlayer 12 inside the shell wall of the insulation shell 3 achieves the purpose of heat preservation of the valve body 1.

[0027] In this embodiment, a first rubber ring 8 is embedded in the pipe adapter hole 7, and a second rubber ring 10 is embedded in the valve stem adapter hole 9. The first rubber ring 8 and the second rubber ring 10 are symmetrically divided into two parts. The first rubber ring 8 is used to connect with the conveying pipe 2 to seal the pipe adapter hole 7, and the second rubber ring 10 is used to connect with the valve stem to seal the valve stem adapter hole 9. The first rubber ring 8 and the second rubber ring 10 have multiple cavities 14 arranged in a ring shape. The cavities 14 improve the elasticity of the first rubber ring 8 and the second rubber ring 10, allowing them to more easily and tightly fit with the conveying pipe 2 and the valve stem after the two insulation shells 3 are fitted onto the valve body 1. Rubber strips 11 are provided on the cutting surfaces of the two insulation shells 3 to seal the mating surfaces of the two insulation shells 3.

[0028] As a preferred technical solution in this embodiment, slots 15 are provided on the two first edge plates 5. The connecting member 6 includes a pull rod 16 rotatably installed in the slot 15 on one of the first edge plates 5. A push plate 17 and a spring 19 are movably sleeved on the pull rod 16. An end plate 18 is fixed to the end of the pull rod 16. The spring 19 is located between the end plate 18 and the push plate 17. A pair of pull rings 20 are provided on the side of the push plate 17, and the pull rings 20 are distributed towards the end plate 18. With this structural design, after the two heat insulation shells 3 are fitted onto the valve body 1, the pull rings 20 can be held to pull the push plate 17 towards the end plate. Move the rod 18 while rotating the pull rod 16 so that it passes through the slots 15 on the two first edge plates 5. After releasing the push plate 17, the spring 19 pushes the push plate 17 to press against the adjacent first edge plate 5. At this time, the pull rod 16 cooperates with the end plate 18, the spring 19 and the push plate 17 to limit the connection of the two first edge plates 5, thereby connecting and closing the two heat insulation shells 3 so that they are fitted onto the valve body 1. After pulling the push plate 17 to squeeze the spring 19 and rotating the pull rod 16 to the other side, the two heat insulation shells 3 can be opened and removed from the valve body 1. The operation is simple and the heat insulation shells 3 are easy to install and remove.

[0029] Working principle: In use, the two insulation shells 3 are hinged and rotated onto the valve body 1 using the second flange 21. The conveying pipe 2 connecting the valve body 1 passes through the pipe adapter holes 7 at both ends of the insulation shell 3. The first rubber ring 8 inside the pipe adapter hole 7 is tightly fitted with the conveying pipe 2. The valve stem of the valve body 1 passes through the valve stem adapter hole 9 on the boss 4. The second rubber ring 10 inside the valve stem adapter hole 9 is tightly fitted with the valve stem. Then, by holding the pull ring 20, the push plate 17 is pulled towards the end plate 18, while the pull rod 16 is rotated to pass through the slots 15 on the two first flanges 5. After releasing the push plate 17, the spring 19 pushes the push plate 17 against the adjacent first flange 5, limiting the connection between the two first flanges 5, thereby connecting the two insulation shells. The insulation sleeve 3 is closed and fitted onto the valve body 1. Utilizing the excellent insulation performance provided by the insulation layer 13 on the inner wall of the insulation sleeve 3 and the insulation interlayer 12 within the shell wall of the insulation sleeve 3, the valve body 1 is insulated. This prevents heat loss from the valve body 1 or temperature changes due to the external environment from affecting the utilization efficiency of the conveying medium, equipment operation safety, and product quality. Furthermore, the insulation structure of the valve body 1 adopts a rotating fit of two insulation sleeves 3 and a connection method using connectors 6. It can be installed onto or removed from the valve body 1 simply by pulling the lever 16 to rotate. It is easy to install and remove, reusable, and does not require a lot of manpower and time during installation and removal, which is beneficial for the maintenance of the valve body 1 and makes it more practical.
