Description

Technical Field

[0001] The utility model belongs to the technical field of heat preservation pipe maintenance, and particularly relates to a moisture exhaust device for heat preservation pipes. Background Art

[0002] The heat preservation pipe is short for the heat insulation pipe, which is used for the transportation of liquids, gases and other media, and is used in the heat insulation projects of pipelines such as petroleum, chemical industry, aerospace, central heating, central air conditioning, and municipal administration. The existing moisture exhaust device for prefabricated heat preservation pipes is an intermediate connecting piece used to connect heat preservation pipes. Usually, the structure is similar to that of the heat preservation pipe. In order to achieve moisture-proof of the heat preservation layer of the heat preservation pipe, a moisture exhaust device will be installed at the corresponding position in the heat preservation pipe.

[0003] The existing devices are difficult to adapt to diverse humid conditions. During actual use, there may be a small section of the heat preservation layer that is humid, there may be moisture in a long section of the heat preservation layer inside the pipe, or it may be difficult to determine the position where the heat preservation pipe leaks. When facing a changing environment, the existing technologies often achieve the goal by adding a large number of moisture exhaust and air extraction devices. The cost is relatively high.

[0004] Therefore, we propose a moisture exhaust device for heat preservation pipes to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the existing technology that it is difficult to adapt to different humid conditions, and to propose a moisture exhaust device for heat preservation pipes.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A moisture exhaust device for heat preservation pipes includes a heat preservation pipe body and multiple sections of moisture exhaust pipes sequentially sleeved on the heat preservation pipe body. Adjacent moisture exhaust pipes are connected by a connecting piece. There are gaps for air flow between the moisture exhaust pipe and the heat preservation pipe, and between the connecting piece and the heat preservation pipe;

[0008] On both sides of the top of the moisture exhaust pipe, there are communication pipes connecting the outside and the inside of the moisture exhaust pipe. On one side of the communication pipe, there is a fixing rod fixedly connected to the moisture exhaust pipe. The upper end of the fixing rod is movably sleeved with a conversion plate. One end of the conversion plate is fixedly provided with a sealing plate for sealing the top of the communication pipe, and the other end is detachably provided with a filter plate for covering the top of the communication pipe;

[0009] On one side of the filter plate, there is a groove. On both sides of the end of the conversion plate facing the filter plate, there are installation grooves, and elastic clamping blocks matching the groove are arranged in the installation grooves. One side of the elastic clamping block is fixedly connected with a pressing rod for driving the deformation of the clamping block, and the pressing rod extends to the outside of the filter plate.

[0010] Preferably, a limiting plate is fixedly connected to the top end of the fixed rod, and the conversion plate rotates and vertically slides on the fixed rod below the limiting plate.

[0011] Preferably, a limiting block is fixedly connected to one side of the bottom surface of the conversion plate.

[0012] Preferably, the bottom surface of the limiting block is always lower than the top surface of the communicating pipe during the working process.

[0013] Preferably, sealing rings are fixedly connected to the bottom surfaces of the sealing plate and the filter plate, and sealing grooves for mating with the sealing rings are formed at the top end of the communicating pipe.

[0014] Preferably, the elastic clamping block is in a J shape, and gaps for the elastic clamping block to deform are provided between the elastic clamping block and the installation groove, and between the elastic clamping block and the groove.

[0015] In summary, the technical effects and advantages of the present utility model are as follows: for this heat preservation pipe moisture exhaust device, by sleeving a plurality of moisture exhaust pipes on the heat preservation pipe body and cooperating with the communicating pipe, it is possible to observe and monitor the water leakage and moisture conditions of different sections of the heat preservation pipe; by covering the filter plate or the sealing plate on the top end of the communicating pipe according to the situation through the conversion plate, the starting point and the ending point of the air extraction and moisture exhaust line can be conveniently changed. Compared with the existing devices, the problem of needing to add a large number of moisture exhaust and air extraction devices to adapt to different situations is avoided, the cost is reduced, and the applicability of the device is improved.

[0016] In addition, the positioning of the filter plate is realized through the elastic clamping block and the groove, and the clamping block is separated from the groove through the pressing rod, thereby unlocking the filter plate, and thus realizing the quick disassembly and replacement of the filter plate, improving the maintenance efficiency of the device.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figure 1 、 Figure 5 , a moisture exhaust device for an insulation pipe, including an insulation pipe body 1 and multiple sections of moisture exhaust pipes 2 sequentially sleeved on the insulation pipe body 1. Adjacent moisture exhaust pipes 2 are connected by bolts through a connector 3. There are gaps 4 for air flow between the moisture exhaust pipe 2 and the insulation pipe, and between the connector 3 and the insulation pipe. The outer side of the insulation pipe body 1 should be wrapped with an insulation layer, and air circulates between the gaps 4, providing a basis for subsequent planning of the moisture exhaust route.

[0025] On both sides of the top of the moisture exhaust pipe 2, there are connecting pipes 5 connecting the outside and the inside of the moisture exhaust pipe 2. On one side of the connecting pipe 5, there is a fixed rod 6 fixedly connected to the moisture exhaust pipe 2. The upper end of the fixed rod 6 is movably sleeved with a conversion plate 7. One end of the conversion plate 7 is fixedly provided with a sealing plate 8 for sealing the top of the connecting pipe 5, and the other end is detachably provided with a filter plate 9 for covering the top of the connecting pipe 5;

[0026] On one side of the filter plate 9, there is a groove 10. On both sides of the end of the conversion plate 7 facing the filter plate 9, there are installation grooves 11, and elastic clamping blocks 12 matching the groove 10 are arranged in the installation grooves 11. One side of the elastic clamping block 12 is fixedly connected with a pressing rod 13 for driving the deformation of the clamping block, and the pressing rod 13 extends to the outside of the filter plate 9.

[0027] For this moisture exhaust device of the insulation pipe, during detection, a detection component for detecting air humidity can be set at the connecting pipes 5 of multiple moisture exhaust pipes 2. When an alarm occurs in one or several detection components, the lines where these detection components are located can be used as the exhaust and dehumidification lines. Move up and rotate the conversion plates 7 on one side of the head and tail two connecting pipes 5 of this line until the sealing plate 8 at the top of the connecting pipe 5 is replaced with a filter plate 9. At this time, press down the conversion plate 7 and install the air extraction component on the upper end of one of the filter plates 9, and a blower component can be added to the upper end of the other filter plate 9 as needed.

[0028] The function of the filter plate 9 is to capture the humid water vapor in the air. Dry air and moisture-absorbing substances such as anhydrous calcium chloride and anhydrous magnesium sulfate should be filled inside the filter plate 9. The outside air enters the moisture exhaust pipe 2 after being dried by the filter plate 9, and the humid air in the moisture exhaust pipe 2 is discharged after being dried by the filter plate 9, so that air extraction and moisture exhaust can be carried out for this line.

[0029] When the humidity inside the pipeline is relatively serious, the top of the connecting pipe 5 in the middle of the line can be replaced with the filter plate 9 as appropriate, and an air extraction component or a blower component can be added.

[0030] When the filter plate 9 needs to be replaced, only need to press the pressure rods 13 on both sides of the filter plate 9 at the same time, and the elastic clamping blocks 12 are separated from the grooves 10, then the old filter plate 9 can be removed. When installing the new filter plate 9, only need to align the groove 10 with the elastic clamping block 12, and push the filter plate 9 horizontally towards the elastic clamping block 12. When hearing a "click" sound, it means that the elastic clamping block 12 and the groove 10 are successfully paired, and the replacement of the filter plate 9 can be realized.

[0031] Refer to Figure 4 In order to prevent the conversion plate 7 from detaching from the fixed rod 6 during the movement process, a limit plate 14 is fixedly connected to the top of the fixed rod 6. The conversion plate 7 rotates and vertically slides on the fixed rod 6 below the limit plate 14. The rotation of the rotating ring plate can realize the back-and-forth switching between the sealing plate 8 and the filter plate 9.

[0032] One side of the bottom surface of the conversion plate 7 is fixedly connected with a limit block 15, and the limit block 15 can provide a limit for the conversion plate 7 so that it can only rotate half a circle. The bottom surface of the limit block 15 is always lower than the top surface of the connecting pipe 5 during the working process. Without affecting the function of the device, when manually switching, there is no need to align the sealing ring 16 with the sealing groove 17. Only need to press the conversion plate 7 with one side of the limit plate 14 close to the connecting pipe 5, and the switching can be completed. The maintenance efficiency is improved.

[0033] Refer to Figure 2 As shown in

[0034] Refer to Figure 3, the elastic clamping block 12 is J-shaped, and there are gaps for the deformation of the elastic clamping block 12 between the elastic clamping block 12 and the installation groove 11, and between the elastic clamping block 12 and the groove 10. The quick disassembly of the filter plate 9 is realized by the cooperation of the elastic clamping block 12 and the groove 10. Since the top of the communication pipe 5 needs to use the sealing plate 8 to ensure airtightness when moisture exhaust is not required, the filter plate 9 can be directly removed; when moisture exhaust is required, the communication pipe 5 will provide stable support for the filter plate 9. Therefore, the clamping block will not bear a large force, so the clamping block is selected to cooperate with the groove 10.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
