Description

A B port control device for eliminating wrinkles in the pipe

technical field

The present disclosure relates to the technical field of repairing thermoplastic forming pipes, in particular to a B port control device for eliminating wrinkles in the pipe.

Background technique

The FIPP in-situ thermoplastic pipe repair technology is to heat and soften the factory-prefabricated I-shaped or C-shaped liner at the construction site, drag it into the original pipe, and make it close to the original pipe by heating and pressurizing. There is an inner wall of the pipe, and then it is cooled to form a lined pipe with structural strength to achieve the repair of aging pipes. During the pipeline repair process, the small diameter liner may be wrinkled due to the accumulation of water inside the pipeline.

Liner wrinkles can be quickly pressed and released through the liner for several times to squeeze out the accumulated water inside the pipeline, thereby eliminating the wrinkles generated during the repair process of the liner. When the existing B port control device for repairing a thermoplastic formed pipe rapidly pressurizes the liner, it cannot quickly and accurately control the internal pressure of the liner. When the pressure exceeds a certain value, the liner will be swelled and broken.

beneficial effect

The invention is applied to the repairing project of FIPP thermoplastic forming pipeline, and the air inlet is connected with the special steam plug through the duct. After the liner repaired by thermoplastic molding is preheated and dragged into the pipeline to be repaired, the A and B ends of the liner are inserted into special steam plugs. According to the specific usage, after the FIPP liner is preheated, the liner is kept warm and pressure maintained by adjusting the valve. At this time, the FIPP liner will expand, and the FIPP liner and the pipeline to be repaired will closely fit together. Due to the accumulation of water inside the pipeline, the FIPP liner will be wrinkled. At this time, you can start to release and pressurize the inside of the FIPP liner through the 90° ball valve. Repeated circulation can remove the accumulated water in the pipeline and eliminate the wrinkles of the FIPP liner. pleated. The invention can realize the rapid pressure holding and releasing cycle operation while ensuring that the pressure inside the liner does not exceed the set value, thereby realizing the safe discharge of accumulated water in the pipeline and eliminating the wrinkles of the liner.
