Receiving tube plugging technology and pipeline maintenance process

Receiving ball



At present, for the maintenance and replacement, nearly closed launcher pipeline or pipeline valve components of the pipeline maintenance and waste branch operations, including the commonly used occluder baffle: bag type plug, and disc pipeline occluder。 But most of them need to use multiple pipeline plugging device for pipeline with pressure opening hole plugging operation, occluder operation, complex process, high cost of operation。 The receiving ball cylinder head and block pipeline occluder fast ball cylinder with pressure pipeline, receiving open hole plugging device to complete the operation。 At the end of the operation, the operation procedure is simplified, the process is simple and the safety is high, and the cost is lower than the traditional operation mode。 In charge launcher can be received occluder launcher valve replacement and maintenance work, abandoned branch pipeline; pipeline valve repair and replacement work。

The process flow diagram of the valve replacement and maintenance of the receiving and transmitting tube

1) first close the valve, close close launcher occluder head through receiver & launcher injection.

2) open the normal valve and damage the valve, the valve will be blocked by the end of the valve, and sealing.

3) return the hydraulic control cables, repair or replace the damaged valve.

4) to the hydraulic control cable, and injected into the flange sealing test unit, respectively, on the replacement of the valve distal and proximal flange sealing test, if the seal is intact from the flange sealing test unit, if the seal is required to seal failure and detection。

5) release and return the plugging head, close the valve.

6) exit blocking equipment, job completion. If the sending and receiving ball cylinder valves for the micro leakage of the valve, the valve is closed micro leakage, leakage in the barrel within the allowable range, the receiving ball cylinder proximal no other valve normal circumstances, can still be used near close valve replacement and maintenance task launcher device.
