Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline heat preservation, in particular to a heat preservation device at a pipeline valve position. Background Art
[0002] In the field of sewage treatment, pipes are used to collect and transport sewage. Valves and other control devices are also installed on the pipes to regulate flow and maintain the stability of the pipeline network. When the pipes are transporting sewage, parts of the pipes are exposed to the natural environment.
[0003] When the ambient temperature is low, the pipes need to be insulated to prevent freezing and condensation in the pipes, thereby ensuring the normal operation of the sewage treatment system. Insulation measures are generally taken by wrapping insulation materials such as polyurethane foam, rock wool or aluminum silicate fiber around the outside of the pipes to form a closed insulation layer.
[0004] However, since valves will be installed on the pipeline, such as Figure 6 As shown, a step is formed between the valve connecting pipe and the sewage delivery pipe. Therefore, the insulation device at the pipeline valve position is usually divided into two groups, one group wraps the sewage delivery pipe, and the other group wraps the valve connecting pipe. There is no connection mechanism between the two groups of insulation devices, which makes it easy for cold air to enter the junction between the two, causing a negative impact on the insulation of the pipeline and valve. Utility Model Content
[0005] The main purpose of the present utility model is to provide a heat preservation device for the position of pipeline valves, in which the first sleeve and the second sleeve can be tightly connected to each other. Under the action of the limit device and the positioning ring, the cold wind can be effectively prevented from blowing into the junction of the first sleeve and the second sleeve, thereby improving the heat preservation performance of the heat preservation device for pipelines and valves.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A thermal insulation device for a pipeline valve position comprises two groups of first sleeves located on the periphery of the pipeline and a second sleeve located on the periphery of the valve connecting pipe, the two groups of first sleeves being located on both sides of the valve respectively, a first thermal insulation layer being provided in the first sleeve, a second thermal insulation layer being provided in the second sleeve, positioning rings being provided on opposite sides of the second sleeve, a limiting device being provided on the inner side of the positioning ring, a limiting groove being provided on the first sleeve matching the limiting device, the limiting device being used to be inserted into the limiting groove to connect the first sleeve and the second sleeve.
[0008] Furthermore, the limiting device is a semi-annular plug-in block, and the limiting groove is a semi-annular slot.
[0009] Furthermore, a heat preservation strip is provided on the side of the positioning ring located inside the second sleeve.
[0010] Furthermore, the thermal insulation strip and the second thermal insulation layer are integrally formed.
[0011] Furthermore, the first insulation layer, insulation strips and second insulation layer are all made of rock wool.
[0012] Furthermore, the first sleeve and the second sleeve are made of iron sheet or aluminum sheet.
[0013] Furthermore, the second housing is provided with a through hole that matches the shape of the valve stem, and the valve stem of the valve passes through the through hole and is located outside the second housing.
[0014] Furthermore, the first sleeve and the second sleeve are respectively fixed by iron wires to form a hollow cylinder.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. After the first sleeve of the utility model is wrapped around the pipes on both sides of the valve, the second sleeve will be wrapped around the connecting pipe of the valve. At this time, the positioning ring will contact the surface of the first sleeve, and the limiting device can be inserted into the limiting groove on the surface of the first sleeve, so that the first sleeve and the second sleeve can be tightly connected to each other. Under the action of the limiting device and the positioning ring, it can effectively prevent cold air from blowing into the junction of the first sleeve and the second sleeve, thereby improving the thermal insulation performance of the present thermal insulation device for the pipe and valve.
[0017] 2. The second cover of the utility model is provided with a through hole that matches the shape of the valve stem, so the valve stem passes through the through hole and is located outside the second cover. Therefore, the valve stem will not affect the wrapping operation of the second cover. The second cover can make the second insulation layer fully contact with the valve connecting pipe to avoid air leakage, thereby improving the insulation performance of the second insulation layer on the valve connecting pipe.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0028] like Figure 1-5 As shown, a thermal insulation device for a pipeline valve position includes two groups of first sleeves 4 located on the periphery of the pipeline and a second sleeve 1 located on the periphery of the valve connecting pipe. The two groups of first sleeves 4 are respectively located on both sides of the valve. A first thermal insulation layer 401 is provided in the first sleeve 4, and a second thermal insulation layer 103 is provided in the second sleeve 1. Positioning rings 101 are provided on opposite sides of the second sleeve 1, and a limiting device 102 is provided on the inner side of the positioning ring 101. A limiting groove 402 matching the limiting device 102 is opened on the first sleeve 4, and the limiting device 102 is used to be inserted into the limiting groove 402 to connect the first sleeve 4 and the second sleeve 1.
[0029] In this embodiment, if Figure 6 As shown in the figure, after the valve is connected to the pipe, a step will be formed between the valve and the pipe; Figures 1 to 5As shown, when installing the insulation device, first wrap the two first sleeves 4 on the pipes on both sides of the valve, so that the first insulation layer 401 can have an insulation effect on the pipes on both sides of the valve, and then wrap the unfolded second sleeve 1 on the valve connecting pipe. At this time, since the second sleeve 1 is provided with a through hole 104 that matches the shape of the valve stem, the valve stem of the valve passes through the through hole 104 and is located outside the second sleeve 1. Therefore, the valve stem will not affect the wrapping operation of the second sleeve 1, and the second sleeve 1 can make the second insulation layer 103 fully connected to the valve connecting pipe. The pipes are in contact with each other to avoid air leakage, thereby improving the thermal insulation performance of the second insulation layer 103 on the valve connecting pipe. When the second sleeve 1 is rolled into a cylindrical shape, the positioning ring 101 will contact the surface of the first sleeve 4, and the limiting device 102 can be inserted into the limiting groove 402 on the surface of the first sleeve 4, so that the first sleeve 4 and the second sleeve 1 can be tightly connected to each other. Under the action of the limiting device 102 and the positioning ring 101, cold wind can be effectively prevented from blowing into the junction of the first sleeve 4 and the second sleeve 1, thereby improving the thermal insulation performance of the insulation device for pipes and valves.
[0030] like Figure 7 and Figure 8 As shown, the limiting device 102 and the positioning ring 101 are long strips and have triangular grooves when the second sleeve 1 is unfolded, so that when the limiting device 102 is rolled into a cylindrical shape, the positioning ring 101 can become a ring and the limiting device 102 can become a semi-ring. This is the existing technology and will not be elaborated here.
[0031] Among them, Figure 2 and Figure 3 As shown, the limiting device 102 is a semi-annular plug when the second sleeve 1 is rolled into a cylindrical structure, and the limiting groove 402 is a semi-annular slot when the first sleeve 4 is rolled into a cylindrical shape. The semi-annular plug can be inserted into the semi-annular slot, thereby connecting the first sleeve 4 and the second sleeve 1.
[0032] Among them, an insulation strip 105 is provided on the side of the positioning ring 101 located inside the second sleeve 1. The insulation strip 105 and the second insulation layer 103 are integrally formed. The first insulation layer 401, the insulation strip 105 and the second insulation layer 103 are all made of rock wool. The insulation strip 105 also has a groove body that matches the triangular groove on the positioning ring 101, so that it can form a regular circular ring when it is rolled up.
[0033] Among them, Figures 1 to 3 As shown, the first sleeve 4 and the second sleeve 1 are made of iron or aluminum sheets with a thickness of 1 mm to 3 mm, so that they can be easily rolled into a cylinder or unfolded. When the first sleeve 4 and the second sleeve 1 are rolled into a cylinder, they are fixed with iron wire 3 to ensure that the first sleeve 4 and the second sleeve 1 are rolled into a hollow cylinder.
[0034] Working principle, first, wrap the two first sleeves 4 on the pipes on both sides of the valve, so that the first insulation layer 401 can have an insulation effect on the pipes on both sides of the valve. At this time, the limiting groove 402 is a semi-annular slot, and then wrap the unfolded second sleeve 1 on the valve connecting pipe. At this time, since the second sleeve 1 is provided with a through hole 104 that matches the shape of the valve stem, the valve stem of the valve passes through the through hole 104 and is located outside the second sleeve 1. Therefore, the valve stem will not affect the wrapping operation of the second sleeve 1. The second sleeve 1 can make the second insulation layer 103 fully contact with the valve connecting pipe to avoid air leakage, thereby improving the insulation performance of the second insulation layer 103 on the valve connecting pipe. When rolled into a cylindrical shape, the positioning ring 101 will contact the surface of the first sleeve 4, and the limiting device 102 can be inserted into the limiting groove 402 on the surface of the first sleeve 4, so that the first sleeve 4 and the second sleeve 1 can be tightly connected to each other. Under the action of the limiting device 102 and the positioning ring 101, the cold wind can be effectively prevented from blowing into the junction of the first sleeve 4 and the second sleeve 1, thereby improving the insulation performance of the insulation device for pipes and valves. After the first sleeve 4 and the second sleeve 1 are wrapped, the two should be fixed with the wire 3. When disassembling, the wire 3 should be removed first, and then the second sleeve 1 should be unfolded so that it is no longer connected to the first sleeve 4. Then the second sleeve 1 should be unfolded to separate it from the pipe to complete the disassembly operation.
