Description

Technical Field

[0001] The utility model relates to the technical field of pipeline plugging, in particular to a leakage plugging mechanism for a pipeline compensator. Background Art

[0002] Pipeline compensators are also called expansion joints or expansion joints. They are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the temperature changes, the pipeline cannot shrink and expand completely freely, thermal stress will be generated in the pipeline. This stress must be considered in the pipeline design, otherwise it may cause the pipeline to rupture and affect the normal production. As an important part of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines. Pipeline compensators are divided into corrugated compensators, sleeve compensators, etc.

[0003] When a pipeline is damaged, a leak will appear on it. If the leak is not sealed in time, water will flow out of the leak hole in the pipeline, and then flow out from the gap between the pipeline compensator and the pipeline, affecting the use of the pipeline compensator and even the entire pipeline. In the existing traditional technology, the pipeline compensator is usually removed to repair the blockage. This method is not only time-consuming and labor-intensive, but also inefficient and may damage the pipeline. Therefore, a leakage sealing mechanism for a pipeline compensator is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a leakage plugging mechanism for a pipeline compensator, which has the advantages of saving time and effort and having high leakage plugging efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leakage plugging mechanism for a pipeline compensator, comprising a pipeline body, a pipeline compensator is sleeved on the middle surface of the pipeline body, annular sleeves are installed at both ends of the pipeline compensator, and a plugging structure is arranged in each of the two annular sleeves;

[0006] The blocking structure includes an insertion rod, which is movably installed in the middle position of the top of the annular sleeve, and a plug is fixedly installed on the top of the insertion rod. A pipeline blocking airbag is arranged in the middle of the inside of the annular sleeve, and a connecting air pipe is fixedly installed at the bottom of the pipeline blocking airbag, a ventilation joint is fixedly installed at the bottom of the connecting air pipe, and a pressure gauge is fixedly installed on the right outer surface of the connecting air pipe.

[0007] Furthermore, the two annular sleeves are sleeved on the surface of the pipeline body.

[0008] Furthermore, a slot is provided on the surface of the pipe body, and a plug hole is provided on the surfaces of the two annular sleeves.

[0009] Furthermore, a rubber layer is provided on the surface of the plug, a guide tip is fixedly installed on the top of the pipeline plugging airbag, and a plurality of grooves are opened on the inner wall of the annular sleeve.

[0010] Furthermore, a guide groove is provided on the inner top wall of the annular sleeve, a plurality of sealing rings are provided on the surface of the pipe sealing airbag, a three-way control valve is fixedly installed on the left side of the connecting air pipe, limit plates are fixedly installed on the left and right sides of the connecting air pipe, anti-slip texture is provided on the surface of the pipe sealing airbag, and a through hole is provided at the bottom of the annular sleeve.

[0011] Furthermore, the guide groove is matched with the guide tip, and the plurality of sealing rings are evenly spaced and distributed along the axial direction of the connecting air pipe and are adhesively connected to the connecting air pipe.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The leakage plugging mechanism for the pipeline compensator is provided with a plugging structure. When a leak occurs in the pipeline body and needs to be plugged, the annular sleeve is first sleeved on both ends of the pipeline compensator, and then the plug is pressed downward. The plug drives the plug rod to move downward through the insertion hole opened on the surface of the annular sleeve to the slot opened on the surface of the pipe body, and the annular sleeve is fixed. Then, the air inlet pipe of the external compressor is connected to the ventilation joint. The ventilation joint is fixedly connected to the connecting air pipe. The connecting air pipe can be connected to the pipeline plugging air bag through the through hole opened at the bottom of the annular sleeve, and then the three-way control is used. The gas flow is controlled by a valve and a pressure gauge, and the gas enters the pipeline plugging airbag through the connecting air pipe. The pipeline plugging airbag will expand due to the filling of gas. After the pipeline plugging airbag expands, the sealing ring arranged thereon will fit with the groove opened on the inner wall of the annular sleeve, so that the pipeline plugging airbag can completely fill the annular sleeve, thereby sealing the pipeline leak point and blocking the gap between the pipeline compensator and the pipeline. Through the above arrangement, not only the work efficiency of the staff is improved, but also the loss caused by arbitrary disassembly of the pipeline compensator can be avoided, and it has high practicality.

A plug 402 is fixedly installed on the top of the insertion rod 401. A rubber layer is provided on the surface of the plug 402 to increase friction and facilitate use. A guide tip is fixedly installed on the top of the pipe blocking airbag 403. A guide groove is provided on the inner top wall of the annular sleeve 3. The guide groove is adapted to the guide tip, which is convenient for guiding the pipe blocking airbag 403 so that it can be fixed in the annular sleeve 3.

[0021] A pipeline plugging airbag 403 is arranged in the middle of the annular sleeve 3, and a plurality of sealing rings are arranged on the surface of the pipeline plugging airbag 403. The plurality of sealing rings are evenly spaced along the axial direction of the connecting air pipe 404 and are adhesively connected to the connecting air pipe 404.

The ventilation joint 405 is connected to an external compressor.

[0022] When implementing, follow these steps:

[0023] 1) First, sleeve the annular sleeve 3 on both ends of the pipeline compensator 2;

[0024] 2) Then press the plug 402 to fix the annular sleeve 3 on the pipeline body 1 through the insertion rod 401;
