Abstract

The utility model discloses an online trapping devices of heat medium pipeline, including one with the clamp cover of leak source pipeline outer peripheral face adaptation, press from both sides the cover and include first semicircle subassembly and lower semicircle subassembly, but the cover is established outside this leak source pipeline after first semicircle subassembly and lower semicircle subassembly amalgamation, and the intercommunication has high calandria on the first semicircle subassembly, is equipped with high calandria on the high calandria, is equipped with low calandria on the lower semicircle subassembly, is equipped with low calandria on the low calandria. The online heat medium pipeline leakage repairing device improves the leakage repairing efficiency of the heat medium system pipeline and reduces the influence of leakage repairing on production.

Description

Online leakage repairing device for heat medium pipeline

The technical field is as follows:

the utility model relates to a polyester chemical industry field specifically says to a heat medium pipeline is device of mending leakage on line.

Background art:

in the production process of the polyester filament, many links are required to be carried out in a high-temperature environment, so a heating medium heating and heat preservation system is used, leakage points can appear at the position of a pipeline welding seam or a pipeline quality flaw in the long-term operation process of the system, and if the system is not repaired in time, the stable operation and the safety of the system are affected.

When the heat medium system pipeline leaks, the inlet and outlet valves of the pipeline with the leakage point of the heat medium system are closed firstly according to the conventional leakage repairing mode, the heat transfer oil in the pipeline is discharged out of the pipeline by opening the low discharge valve, then nitrogen is introduced into the pipeline to serve as welding protective gas, then the leakage point is repaired and welded, and the conventional leakage repairing mode is not only low in efficiency but also brings great parking loss to a poly-spinning enterprise.

The utility model has the following contents:

the utility model aims to solve the technical problem that an improve heat medium system pipeline mending leakage efficiency is provided to reduce the online mending leakage device of heat medium pipeline of mending leakage to production influence simultaneously.

The technical solution of the utility model is that, a heat medium pipeline online trapping devices is provided, including one with the clamp cover of leak source pipeline outer peripheral face adaptation, press from both sides the cover and include first semicircle subassembly and lower semicircle subassembly, but the cover is established outside this leak source pipeline after first semicircle subassembly and lower semicircle subassembly amalgamation, the intercommunication has high calandria on the first semicircle subassembly, is equipped with high calandria on the high calandria, is equipped with low calandria on the lower semicircle subassembly, is equipped with low calandria on the low calandria.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: the leakage repairing efficiency of the pipeline of the heat medium system is improved, and the influence of leakage repairing on production is reduced.

Preferably, one end of the high calandria and one end of the low calandria are respectively welded on the upper semicircular component and the lower semicircular component.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1, an online leakage repairing device for a heat medium pipeline comprises a jacket adapted to the outer peripheral surface of a leakage point pipeline 2, the leakage point pipeline is a cylindrical pipeline and comprises an upper semicircular component 11 and a lower semicircular component 12, the upper semicircular component 11 and the lower semicircular component 12 are spliced and then sleeved outside the leakage point pipeline 2 to form a structure of the heat medium jacket, the upper semicircular component 11 is communicated with a high exhaust pipe 3, the high exhaust pipe 3 is provided with a high exhaust valve 31, the lower semicircular component 12 is provided with a low exhaust pipe 4, and the low exhaust pipe 4 is provided with a low exhaust valve 41. For convenient welding, the upper semicircular component and the lower semicircular component are combined to form a locking mouth at two ends, and the inner diameter of the upper semicircular component is consistent with the outer diameter of the leakage point pipeline. When welding, lead to nitrogen gas in the high calandria, all discharge the air in the cover that presss from both sides, the nitrogen gas that is full of in the cover that presss from both sides carries out electric welding protection gas as, then carries out electric welding respectively to the junction of clamp casing spare and heat medium pipeline and handles, and after the electric welding was accomplished, the low row valve of closing the low calandria lets in the conduction oil from the high calandria to close the high row valve.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
