Description

Technical Field

[0001] The utility model relates to the field of pipeline fixing structures, in particular to a heat tracing pipeline fixing device. Background Art

[0002] In the instrumentation industry, heat tracing pipelines are often used for sampling or transportation. A heat tracing pipeline uses electrical energy to supplement the heat lost by the heat-traced body during the process flow, so as to maintain a more reasonable process temperature of the flowing medium. It is a high-tech product. Generally, it consists of Figure 1 the shown gas guide pipe, heating wire, temperature measuring sensor, insulating layer, heat preservation layer and other parts. Heat tracing pipelines are often used for gas transportation between instruments, and it is particularly important to have a firm connection with the instruments. Currently, the commonly used connection method in the market is the through-board ferrule joint. The problem with this method is that some gas guide pipes are relatively thin, and the other parts except the gas guide pipe are relatively heavy. Affected by gravity, the middle part will sag, and the two ends of the joint will be pulled by gravity, which is very likely to cause the gas guide pipe to bend and collapse or even break, posing a great risk. Moreover, the heat preservation layer (usually rubber) is exposed outside, which is not aesthetically pleasing. There are also some heat tracing pipelines at both ends of the equipment fixed by structural parts, and the structural parts and the heat tracing pipelines are bonded together with glue. The problem with this method is that when the temperature of the heat tracing pipeline is too high, the glue will fail and fall off over time, causing danger, and there is still the problem of gravity sag.

[0008] The end of the flexible pipe has a flexible pipe joint;

[0009] One of the flexible pipe joints is screwed onto the threaded part of the reducing bushing, so that the reducing bushing and the flexible pipe are combined to form a channel for the gas guide pipe to pass through the instrument sheet metal part and enter the instrument.

[0010] Preferably, the flexible pipe joint rotates on the threaded part of the reducing bushing until the flexible pipe is in close contact with the reducing bushing and then stops.

[0011] Preferably, the adapter port has a covering structure which is sleeved around the outer periphery of the gas guide pipe to prevent heat in the channel from leaking outwards.

[0012] Preferably, the covering structure is a plurality of valves arranged at the adapter port, and the plurality of valves form a circular notch at the axis of the adapter, and the circular notch is the insertion opening for the gas guide pipe.

[0013] Preferably, the covering structure is a film arranged at the adapter port, and the film is penetrable.

[0014] Preferably, the covering structure is made of a soft material.

[0015] The beneficial effects of the present utility model are as follows:

However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0025] The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0026] Embodiment 1

[0027] In this embodiment, a fixed device for tracing pipeline is proposed. Please refer to Figure 2 , Figure 3 and Figure 5 . The fixed device for tracing pipeline includes an instrument sheet metal part 1. The instrument sheet metal part 1 has a through hole 8. A reducing bushing 2 is inserted into the through hole 8. The threaded part of the reducing bushing 2 extends outwards relative to the instrument sheet metal part 1.

[0028] In this embodiment, the fixed device for tracing pipeline further includes a universal pipe 6. It should be noted that the universal pipe 6 can be bent but not folded. In addition, the universal pipe 6 can fix its shape after being bent.

[0029] Please refer to Figure 2 and Figure 3 . There are two heating wires 3, one temperature measuring wire 4 and one gas guide pipe 5 inside the universal pipe 6.

[0030] Please continue to refer to Figure 2 and Figure 3 . There is a universal pipe joint 7 at the end of the universal pipe 6. One of the universal pipe joints 7 is sleeved on the threaded part of the reducing bushing 2, so that the reducing bushing 2 and the universal pipe 6 are combined to form a channel for the gas guide pipe 5 to pass through the instrument sheet metal part 1 and enter the instrument.

[0031] Compared with Figure 1 the fixed structure of the tracing pipeline shown, the fixed device for tracing pipeline proposed in this embodiment has the advantage that since the universal pipe 6 cannot be folded, the gas guide pipe 5 located inside the universal pipe 6 will not have the problem of pipe blockage caused by pipeline folding.

[0032] In addition, since the universal pipe 6 can fix its shape, the pipeline route can be customized by personnel.

[0033] Embodiment 2

[0034] In this embodiment, a fixed device for tracing pipeline is proposed. Please refer to Figure 2 , Figure 3 and Figure 5, the tracing pipeline fixing device includes an instrument sheet metal part 1. The instrument sheet metal part 1 has a through hole 8, and a reducing bushing 2 is inserted into the through hole 8. The threaded part of the reducing bushing 2 extends outward relative to the instrument sheet metal part 1.

[0035] In this embodiment, the tracing pipeline fixing device further includes a universal pipe 6. It should be noted that the universal pipe 6 can be bent but not folded, and in addition, the universal pipe 6 can fix its shape after being bent.

[0036] Please refer to Figure 2 and Figure 3 , there are two heating wires 3, one temperature measuring wire 4, and one gas guide pipe 5 inside the universal pipe 6.

[0037] Please continue to refer to Figure 2 and Figure 3 , there is a universal pipe joint 7 at the end of the universal pipe 6. Among them, one universal pipe joint 7 is sleeved on the threaded part of the reducing bushing 2, so that the reducing bushing 2 and the universal pipe 6 are combined to form a channel for the gas guide pipe 5 to pass through the instrument sheet metal part 1 and enter the instrument.

[0038] This embodiment is an extended example of Embodiment 1. Specifically, the port of the reducing bushing 2 has a covering structure. The covering structure is sleeved around the periphery of the gas guide pipe 5 to prevent the heat in the channel from leaking outwards.

[0039] Further explanation, the covering structure is a plurality of valves 9 arranged at the port of the reducing bushing 2. The plurality of valves 9 form a circular notch at the axis of the reducing bushing 2, and the circular notch is the insertion port for the gas guide pipe 5.

[0040] Please take Figure 3 as a reference. The inner diameter of the reducing bushing 2 is much larger than the diameter of the gas guide pipe 5. After the gas guide pipe 5 is inserted through the reducing bushing, the space inside the reducing bushing 2 cannot be filled, and the heat in the entire channel will overflow from the reducing bushing 2. In this regard, a plurality of valves 9 are arranged at the port of the reducing bushing 2 to sleeve the gas guide pipe 5, which can prevent the heat from leaking out from the reducing bushing 2.

[0041] In this embodiment, the covering structure is not limited to a plurality of valves 9, and can also be a film (not shown in the figure) arranged at the port of the reducing bushing 2. The film is penetrable. In this way, the gas guide pipe 5 pierces the film and extends outwards, and the heat preservation effect possessed by the plurality of valves 9 is achieved by means of the film.

[0042] In this embodiment, it should be noted that the covering structure is made of soft material.

[0043] In the present utility model, unless otherwise clearly stipulated and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0044] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the descriptions in the specification are only preferred examples of the present utility model, which are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
