Description

A pearl worm equipment that is used for middle-high pressure gas pipeline to implement maintenance and construction operation

Technical Field

The utility model relates to the field of gas pipeline maintenance, in particular to a bead worm device for implementing maintenance and construction operation of a medium-high pressure gas pipeline.

Background

At present, after the gas supply pipeline is delivered and used, a large amount of maintenance, inspection personnel and external detection equipment are put into the gas supply pipeline for timing, post inspection and detection, and the normal operation of the pipeline is ensured in real time.

The processing procedure of pipeline dangerous case or adding supply branch at present is:

because no complete maintenance equipment is matched in the prior art, the temporary cutting (flattening) of the pipeline (or depressurization and gas carrying) can be performed, and the detection and recovery of the supply after the maintenance can be performed. In the construction process, flammable and explosive gas with a certain concentration exists in the gas pipeline and in the construction site environment, so that the potential safety hazard that the flammable gas burns and flashes when meeting a fire source is very easy to occur. Especially when the exact leakage point of the pipeline can not be found, the pipeline is gradually excavated and searched by using machinery, and the protective measures are not in place at the moment, so that the pipeline is extremely dangerous.

When the gas pipeline is welded with gas and pressure on the pipeline after the pressure is reduced, under the condition of unknowing or the peak period of positive gas consumption, the pipeline is tempered due to siphon negative pressure caused by using a large amount of gas, so that serious safety accidents occur.

Therefore, the large-diameter pipeline maintenance construction process is complex and changeable, complicated (emergency notification of valve closing (or bypass temporary supply) of downstream users at accident points, warning isolation of accident areas, night construction explosion-proof illumination, protection spraying, gas blowing-off, gas detection after maintenance, replacement and gas recovery notification) and uncertainty of normal supply time recovery are caused, and the use condition of a stove in the house of resident users after gas recovery is not clear, so that certain hidden hazards exist, and a large amount of gas resources are flushed out at the damaged positions due to leakage, so that resource waste and loss are caused.

In addition, ponding of gas pipeline in the operation, ice blockage in winter are common potential safety hazards, and at present, the ball is adopted, the outer half tropical zone of pipeline is heated and melted or is purged with high-pressure air flow to be disposed, and the mode has the following defects:

1. when the middle-low pressure pipeline adopts an air duct: because the air duct cannot enter the main pipeline for a long distance (1. The sealing between the air duct and the pipeline access port is difficult to solve; 2. The hardness of the air duct is self, (the reverse thrust of the gas);

2. when the high-medium pressure pipeline adopts a ball or sweeps: the factors such as the length, fluctuation, diameter change, branching, steering, no ball passing reserved outlet, high-pressure gas capacity of a gas storage tank and the like of the laid pipeline are caused, when the ball is passed or blown out, water is split in other branches and non-constant diameter pipelines, and secondary collection or backflow deposition (ice blocking is easy to form in winter); or the ball-through construction can not be realized, accumulated water in the maintained pipeline can not be discharged, and the accumulated water is retained in the pipeline.

3. The pipeline has the lowest point position due to the local settlement of the foundation at the pipeline laying position, and the concrete position, water accumulation amount and the like of the pipeline where the ponding is positioned cannot be intuitively judged by the buried pipeline at the ground surface. The ice blockage situation of the pipeline laid on the ground surface occurs in winter, and the semi-tropical ablation is mostly adopted, so that the problem can be solved only temporarily (accumulated water can be secondarily gathered at other low-lying positions to form ice blockage).

4. Because the upstream pipeline is in danger, accumulated water is caused to enter in the maintenance process (after the rush repair is finished, no corresponding suction and discharge or treatment equipment is arranged in the pipeline), the accumulated water can be gradually collected and deposited at the lowest depression of the pipeline under the drive of the flow rate of the pipeline, and specific point positions cannot be visually perceived or can not be predicted.

The accumulated water in the pipeline can gradually flow away, collect and deposit along with the air flow of the pipeline due to factors such as the air consumption of the downstream of the pipeline, the low-lying situation of the pressure regulator and the like, so that the pipeline is blocked again (or frozen and blocked in winter) at other places; the purging or the ablation is not thorough, repeated construction is formed, and a great amount of construction cost and economic loss are brought for each purging and replacing pipeline fuel gas.

With the increase of the service life of urban pipe networks and pipelines, partial buried pipelines are faced to the condition of reaching the service life, and as the actual safety condition inside the pipelines is unknown (such as the corrosion condition of the pipe walls and welded junctions of the pipelines), corresponding decisions on the corresponding pipelines are difficult to make. The pipeline laid in urban greening areas and under roads is inspected, detected or replaced integrally after being excavated integrally, so that the pipeline is not realistic, and only can be temporarily used or new pipelines can be laid in a planning mode after risk delay.

The newly laid pipeline is welded and spliced, and currently known splicing equipment can only perform straight-line and equal-diameter pipeline and pipe fitting splicing, and can not realize forward and backward splicing of the elbow and the reducer pipe fitting. The pipeline closing device has single use function.

Therefore, there is a need to design a bead worm device for performing maintenance and construction work on existing gas pipelines to solve the above problems.
