Description

Technical Field

[0001] This utility model belongs to the technical field of valve body insulation devices, specifically relating to a valve body insulation mechanism. Background Technology

[0002] The valve body is the main structural part of the valve, usually made of metal or plastic. Its function is to provide a space to accommodate and support the internal components of the valve, and to control the flow of fluid through corresponding channels. The design and shape of the valve body directly affect the valve's performance, fluid resistance and sealing effect. The valve body is usually combined with other components such as the valve cover, valve stem and seals to ensure the normal operation and reliability of the valve.

[0003] In the process of heat preservation of valve body, traditional heat preservation cover is usually fixed to the outside of valve body with bolts. Although this design provides heat preservation effect to a certain extent, it has some significant defects in practical application. First, when the valve body needs to be disassembled or repaired, the traditional bolt fixing method is particularly cumbersome. Operators need to spend a lot of time and energy to disassemble and install the heat preservation cover, which greatly affects work efficiency. Therefore, a valve body heat preservation mechanism is proposed to solve the above problems. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a valve body insulation mechanism, which has the advantages of simplifying the disassembly and installation process, improving work efficiency, and reducing labor intensity.

[0005] To achieve the above objectives, this utility model provides a valve body insulation mechanism, including an upper insulation cover and a lower insulation cover. Both the upper and lower insulation covers are arc-shaped and hinged to each other at one end. The inner walls of both the upper and lower insulation covers are equipped with insulation layers.

[0006] A set of limiting components is assembled on the outer periphery of the lower insulation cover;

[0007] The limiting component includes a mounting box, which has a rectangular cavity and two positioning plates are installed inside the rectangular cavity. A sleeve is provided through one side of each of the two positioning plates and extends through one side of the mounting box. A sliding rod is slidably provided inside each of the two sleeves. A limiting block is installed on the inner end of each of the two sliding rods. A compression spring is sleeved on the outside of each of the two sliding rods, and the two ends of the compression spring are hooked to the limiting block and one side of the sleeve, respectively.

[0008] As a further improvement of this utility model, a connecting plate is assembled on the outer periphery of the upper heat insulation cover, a connecting column is assembled on the lower end face of the connecting plate, and a positioning plate is assembled on the lower end face of the connecting column, with the positioning plate located between two limiting blocks.

[0009] As a further improvement of this utility model, the two limiting blocks are rotatably connected to rollers on opposite sides via rotating shafts, and the rollers abut against the bottom wall of the rectangular cavity of the mounting box. A support seat is assembled at the center of the bottom wall of the rectangular cavity of the mounting box.

[0010] As a further improvement of this utility model, a limit plate is fitted to the outer ends of both slide rods.

[0011] As a further improvement of this utility model, both of the limiting blocks have an inclined surface at the upper end and a slot at the lower end.

[0012] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0013] This utility model's valve body insulation mechanism, through the cooperation of components within the set limiting assembly, allows the two limiting blocks to move outward by pulling the sliding rods to both sides, thereby removing the limitation on the positioning plate. This enables the upper and lower insulation covers to be separated and disassembled. The operation is simple and convenient, reducing operational complexity and allowing maintenance personnel to complete the work in a shorter time, significantly improving work efficiency. It is particularly suitable for environments requiring frequent maintenance and inspection. Traditional bolt disassembly requires tools and often increases labor intensity due to bolt jamming or difficulty in disassembly. However, this device achieves quick disassembly and fixation of the upper and lower insulation covers through compression spring limiting and sliding rod pulling, making the operation easier and faster, reducing the labor intensity of workers. No additional tools are required; operators only need to manually pull the sliding rods to complete the disassembly of the upper and lower insulation covers, enhancing operational convenience and comfort.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Example

[0020] Depend on Figure 1-3 A valve body insulation mechanism is provided, comprising an upper insulation cover 1 and a lower insulation cover 2. Both the upper insulation cover 1 and the lower insulation cover 2 are arc-shaped and are hinged to each other at one end. The inner walls of both the upper insulation cover 1 and the lower insulation cover 2 are equipped with insulation layers 3.

[0021] A set of limiting components 4 are assembled on the outer periphery of the lower insulation cover 2;

[0022] The limiting component 4 includes a mounting box 40, which has a rectangular cavity and two positioning plates 41 are installed inside the rectangular cavity. A sleeve 42 is provided through one side of each of the two positioning plates 41 and extends through one side of the mounting box 40. A slide rod 43 is slidably provided inside each of the two sleeves 42. A limiting block 44 is installed on the inner end of each of the two slide rods 43. A compression spring 45 is sleeved on the outside of each of the two slide rods 43 and the two ends of the compression spring 45 are hooked to the limiting block 44 and one side of the sleeve 42, respectively.

[0023] The outer periphery of the upper insulation cover 1 is equipped with a connecting plate 11, the lower end face of the connecting plate 11 is equipped with a connecting column 12, the lower end face of the connecting column 12 is equipped with a positioning plate 13, and the positioning plate 13 is located between two limit blocks 44.

[0024] In this embodiment, through the cooperation between the components within the limiting assembly 4, the two limiting blocks 44 are moved outward by pulling the slide bar 43 to both sides, thereby canceling the limitation on the positioning plate 13. This allows the upper insulation cover 1 and the lower insulation cover 2 to be separated and disassembled. The operation is simple and convenient. This device reduces the complexity of operation, enabling maintenance personnel to complete the work in a shorter time, significantly improving work efficiency. It is particularly suitable for environments that require frequent maintenance and inspection. Traditional bolt disassembly requires tools and often increases labor intensity due to bolt jamming or difficulty in disassembly. However, this device achieves quick disassembly and fixation of the upper insulation cover 1 and the lower insulation cover 2 through the limiting of the compression spring 45 and the pulling of the slide bar 43. The operation is easier and faster, reducing the labor intensity of the workers. No additional tools are required. The operator only needs to manually pull the slide bar 43 to complete the disassembly of the upper insulation cover 1 and the lower insulation cover 2, enhancing the convenience and comfort of operation.

[0025] Specifically, refer to Figure 1-3The two limiting blocks 44 are rotatably connected to rollers 46 on opposite sides via a rotating shaft, and the rollers 46 abut against the bottom wall of the rectangular cavity of the mounting box 40. A support seat 47 is installed at the center of the bottom wall of the rectangular cavity of the mounting box 40.

[0026] In this embodiment, the roller 46 provided on the outer side of the limiting block 44 can make the limiting block 44 move more smoothly and stably, thereby improving the overall stability of the device. The support base 47 is provided to position and support the positioning plate 13.

[0027] Specifically, refer to Figure 3 Limiting discs 431 are fitted to the outer ends of both slide rods 43.

[0028] In this embodiment, a limiting plate 431 is provided at one end of the slide rod 43 to limit the slide rod 43, so that the slide rod 43 does not exceed the stroke range of the sleeve 42 when it moves.

[0029] Specifically, refer to Figure 2-3 Both limiting blocks 44 have an inclined surface at the top and a slot at the bottom.

[0030] In this embodiment, the inclined surface at the upper end of the limiting block 44 allows the two limiting blocks 44 to move outward when the positioning disk 13 is pressed downward, and the slot at the lower end of the limiting block 44 is used to limit the positioning disk 13.

[0031] The valve body insulation mechanism of this utility model:

[0032] In actual use, when staff need to disassemble and maintain the upper insulation cover 1 and the lower insulation cover 2, they pull the sliding rods 43 to both sides, causing the limiting blocks 44 at one end of the two sliding rods 43 to move outward. This releases the limiting blocks 44 from restricting the positioning plate 13, allowing the upper insulation cover 1 and the lower insulation cover 2 to separate. When it is necessary to install the upper insulation cover 1 and the lower insulation cover 2, they are brought together and assembled. Then, the connecting post 12 on the lower end face of the connecting plate 11 drives the positioning plate 13 to press down on the two limiting blocks 44. Under the action of the upper inclined surface of the two limiting blocks 44, the two limiting blocks 44 are pushed outward and squeeze the compression spring 45. Under the elastic force of the two compression springs 45 and the external tension, the limiting blocks 44 are pushed in the opposite direction, and finally the two limiting blocks 44 are aligned to limit the positioning plate 13, thus realizing the splicing and installation of the upper insulation cover 1 and the lower insulation cover 2.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
