Abstract

The invention belongs to the technical field of pipelines, and discloses a PE pipeline pressure device. The PE pipeline pressure device includes a PE plastic plug, a pressure pipe, a pressure gage, anadjustable valve and an air compressor; the PE plastic plug includes a pipe-shaped connection part and a blocking part; the pipe diameter and thickness of the pipe-shaped connection part are the sameas those of a PE pipeline to be tested; the blocking part seals one end of the pipe-shaped connection part; a round hole is formed in the blocking part, and an internal thread joint is welded to theinterior of the round hole; the first end of the pressure pipe is connected with the internal thread joint through a thread, and the second end of the pressure pipe is connected with the air compressor; the adjustable valve is arranged on the pressure pipe; the pressure gauge is arranged on the pressure pipe and is located between the adjustable valve and the first end of the pressure pipe. The PEpipeline pressure device is simple in structure, convenient to mount and resistant to high pressure; by adopting the PE pipeline pressure device and method, it is convenient to read pressure values inside the pipeline; the PE pipeline pressure device and method have a good sealing effect and can be popularized to plastic pipes of other kinds.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a PE pipeline pressurization device and method. Background technique [0002] In modern industrial production and urbanization construction, pipeline facilities such as underground transportation of water, oil, gas, communication, and power supply are more and more widely distributed. They are often called the main artery of modern industry and urban life, so they are also called lifeline projects. Once these pipelines are damaged and destroyed, in addition to direct losses caused by their own destruction, they will also cause serious secondary disasters such as water cuts, floods, and power outages. Among them, PE pipeline has the characteristics of easy construction, fast speed, corrosion resistance, no pollution, and long service life. It is widely used in lifeline projects such as gas transportation, water supply and drainage, and is the most used pipeline. [0003] When P...
