Description

Technical Field

[0001] This utility model relates to the field of valve insulation technology, specifically to a valve insulation structure. Background Technology

[0002] In the chemical industry, high-viscosity media need to be heated to a fluid state for easy transport in pipelines and valves. At the same time, to prevent the media from crystallizing due to temperature drop during transport, the pipelines and valves need to be insulated. For example, the utility model patent with authorization announcement number CN201407464Y entitled "A Valve Insulation Cover" includes a cover body, which is composed of an inner lining layer, an insulation layer, an insulation material protective mesh layer, and an outer protective layer from the inside out. The inner lining layer, insulation layer, and insulation material protective mesh layer are made of insulation material, and the outer protective layer is made of plastic steel.

[0003] When the valve is under maintenance, the cover needs to be disassembled and then reinstalled after the valve is under maintenance. However, the cover is a single piece fitted onto the valve, and both installation and disassembly require disconnecting the valve from the pipeline at both ends, which results in low efficiency in the installation and disassembly of the cover. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a valve insulation structure to solve the technical problem of low disassembly and assembly efficiency of valve insulation structures in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a valve insulation structure, including:

[0007] The insulation shell includes two relatively connected shells and insulation cotton. Each of the two shells has a receiving cavity on its opposite side. The volume of the receiving cavity is larger than the volume of the valve. The insulation cotton is filled between the shell and the valve. Each of the two shells has an opening at its top, and the diameter of the opening is larger than the diameter of the valve opening. Each of the two shells has a binding groove on its outer surface.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem of low disassembly and assembly efficiency of valve insulation structures, this utility model provides a valve insulation structure that can improve disassembly and assembly efficiency.

[0025] It should be noted that the valve insulation structure described in this utility model is used for, but not limited to, valves, etc. For ease of explanation, this utility model only uses the application of a valve insulation structure to a valve as an example for illustration. The principle of applying a valve insulation structure to other types of equipment is essentially the same as the principle of applying it to a valve, and will not be described in detail here.

[0026] Please see Figure 1 - Figure 3 ,in Figure 1 This is a schematic diagram of a valve insulation structure according to an embodiment of the present invention. The valve insulation structure includes an insulation shell 1 and an insulation cover 2. The insulation shell 1 includes two relatively connected shells 11 and insulation cotton 12. Each of the two shells 11 has a receiving cavity 111 on its opposite surface. The volume of the receiving cavity 111 is larger than the volume of the valve. The insulation cotton 12 is filled between the shell 11 and the valve. Each of the two shells 11 has an opening 112 on its top, and the diameter of the opening 112 is larger than the diameter of the valve opening. Each of the two shells 11 has a binding groove 113 on its outer surface. One side of the insulation cover 2 is hinged to the top of any shell 11.

[0027] In this embodiment, the insulation structure of the valve is formed by the insulation cotton 12 and the insulation cover 2. The insulation cover 2 not only improves the insulation effect, but also protects the valve from opening and closing. Furthermore, the binding groove 113 allows the two shells 11 to be spliced ​​together to form the insulation shell 1, which can be fixed with just a cable tie. When the valve needs to be inspected, the cable tie can be cut off, which effectively improves the disassembly and assembly efficiency.

[0028] It should be noted that disposable nylon cable ties are used. During the disassembly and assembly of the insulation shell 1, simply cut off the cable ties and replace them with new ones.

[0029] In one embodiment, please refer to Figure 2 and Figure 3 A groove 114 is provided on one side of the opposite surface of the two shells 11, and a protrusion 115 is provided on the other side. The groove 114 and the protrusion 115 are adapted to each other.

[0030] In this embodiment, there are several grooves 114 and several protrusions 115. Each groove 114 corresponds to each protrusion 115. By inserting the protrusion 115 into the groove 114, the two shells 11 are positioned, which facilitates the binding of cable ties.

[0031] In one embodiment, please refer to Figure 1 Both shells 11 have an arc groove 116 on their tops and a sealing ring 21 on the bottom of the insulation cover 2. The arc groove 116 and the sealing ring 21 are compatible.

[0032] In this embodiment, the sealing performance of the heat insulation cover 2 is improved to prevent heat loss from the connection between the heat insulation cover 2 and the top of the heat insulation shell 1.

[0033] In one embodiment, please refer to Figure 1 and Figure 2 Each shell 11 has a hinge frame 13 on its top and a hinge plate 22 on one side of the heat insulation cover 2. The hinge plate 22 and the hinge frame 13 are hinged to each other.

[0034] In this embodiment, when the operator needs to operate the valve, the insulation cover 2 can be opened and the valve operated by utilizing the connection between the hinge plate 22 and the hinge frame 13.

[0035] In one embodiment, please refer to Figure 1 and Figure 3 The top of the other housing 11 is provided with a first lock hole 14, and the side of the heat preservation cover 2 is provided with a second lock hole 23. The first lock hole 14 and the second lock hole 23 are compatible.

[0036] In one embodiment, please refer to Figure 1 A locking ring 3 is provided between the first locking hole 14 and the second locking hole 23.

[0037] In this embodiment, the first lock hole 14 and the second lock hole 23 are fixed by the locking ring 3, so that the heat preservation cover 2 cannot be opened, effectively preventing unauthorized personnel from maliciously operating the valve.

[0038] In one embodiment, please refer to Figure 1 - Figure 3 There are two binding grooves 113, which are located at both ends of the housing 11.

[0039] In this embodiment, cable ties are used to bind the two ends of the insulation shell 1 to improve the sealing and stability between the two shells 11 and prevent the two shells 11 from separating on their own.

[0040] In one embodiment, please refer to Figure 1 - Figure 3 Both ends of the two housings 11 are provided with inlets and outlets 117 corresponding to the two ends of the valve.

[0041] In this embodiment, the diameter of the inlet and outlet 117 is the same as the diameter of the pipe, which facilitates the pipes connected to both ends of the valve to be accommodated in the inlet and outlet 117 when the insulation shell 1 is installed.

[0042] In one embodiment, please refer to Figure 2 and Figure 3 The import / export 117 is equipped with a limit ring 118.

[0043] In this embodiment, the function of the limiting ring 118 is to wrap around the flange at the connection between the valve and the pipeline, thereby improving the insulation effect at the connection between the valve and the pipeline. At the same time, the limiting ring 118 plays a positioning role by abutting against the flange at the connection between the valve and the pipeline, which facilitates the installation of the insulation shell 1.

[0044] In one embodiment, please refer to Figure 1 The thermal insulation cotton 12 is made of flame-retardant material.

[0045] In this embodiment, excessively high temperatures are avoided to prevent the insulation cotton 12 from catching fire.

[0046] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0047] During installation, firstly, the two housings 11 enclose the valve, with each protrusion 115 inserted into the corresponding groove 114. Both ends of the two housings 11 enclose the connection between the valve and the pipeline, and the limiting ring 118 abuts against the flange of the pipeline. Then, multiple cable ties are tied to the binding groove 113, thus fixing the two housings 11 and forming the insulation shell 1. Secondly, insulation cotton 12 is stuffed into the receiving cavity 111 through the opening 112. Finally, the insulation cover 2 covers the valve's opening and closing, and the locking ring 3 prevents unauthorized personnel from maliciously operating the valve, thus completing the insulation installation of the valve.

[0048] To disassemble, open the locking ring 3, open the insulation cover 2, and cut off the cable ties (the cable ties are made of nylon and are disposable).

[0049] In summary, this insulation structure not only improves the insulation effect on valves, but also increases the efficiency of installation and disassembly.

[0050] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
