Description
Technical Field
The utility model belongs to the technical field of belong to tubular product processing, in particular to quick detection device of polyethylene winding arrangement wall pipeline interface seal.
Background
The environment-friendly polyethylene winding structure wall pipe is an ideal substitute for metal and cement pipelines. The composite material has the characteristics of light weight, corrosion resistance, low heat conductivity coefficient, good insulating property, small flow resistance, no scale, secondary pollution prevention, long service life, quick construction, convenient maintenance and the like. The spigot-and-socket electrofusion connection type pipeline joint realizes zero leakage and uneven settlement resistance. The product is mainly applied to the collection and discharge of rainwater and sewage of petrochemical industry, ports and docks, power plants (nuclear power and thermal power) and municipal roads.
In the process of laying the pipeline, after the front-end polyethylene winding structure wall pipeline 13 and the rear-end polyethylene winding structure wall pipeline 9 are butted and laid and are qualified through inspection, the pipeline airtightness inspection is carried out, wherein the airtightness inspection mainly detects the airtightness of the interfaces of the front-end polyethylene winding structure wall pipeline and the rear-end polyethylene winding structure wall pipeline. The pipeline tightness test mainly comprises two modes of water-closing test and gas-closing test. The gas-closing test is to seal the two ends of the pipeline with pipe plugs, then to fill air into the pipeline to a certain pressure, and to measure the pressure drop value of the gas in the pipeline in the specified gas-closing time. The water closing test is to fill the test pipe section with water, and to start timing and observe the water seepage amount of the pipeline when the test water head reaches the specified water head. Pipeline leak tightness tests are generally divided by well spacing. Therefore, at present, due to the fact that the test pipe sections need to be filled with water or gas, the two modes have the defects of long required time, low detection efficiency, time and labor waste, resource waste and the like.

Detailed Description
The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.
The utility model provides a quick detection device of polyethylene winding arrangement wall pipeline interface leakproofness, comprises support 5, annular plate 3, curb plate 2, rubber sealing strip 1, business turn over trachea 7, manometer 6, valve 8, and the curb plate symmetry is adorned admittedly in the outer wall of annular plate both ends, and rubber sealing strip corresponds and sets up in the curb plate top, support and annular plate inner chamber, and the business turn over trachea sets up on the support, and manometer, valve set up on business turn over trachea. The rubber sealing belt is provided with an inflation inlet.
The annular plate, the side plate and the rubber sealing strip form an annular air cavity 11 together with the inner wall of the front-end polyethylene winding structure wall pipeline and the inner wall of the rear-end polyethylene winding structure wall pipeline.
The top of the side plate is provided with a supporting plate 4.
The utility model discloses a theory of operation does:
in the construction of the construction site, when the front-end polyethylene winding structure wall pipeline and the rear-end polyethylene winding structure wall pipeline are connected in a socket joint mode, the connection sealing element 12 is adopted for sealing connection, and therefore the tightness of pipe connector connection is guaranteed. After the pipes are connected, connecting a rubber sealing strip of the polyethylene winding structure wall pipe joint tightness rapid detection device 10 with an air pump, then pushing and pulling the polyethylene winding structure wall pipe joint tightness rapid detection device to the pipe joint, filling air into two rubber sealing strips, and enabling the two rubber sealing strips to be respectively and tightly combined and sealed with the inner walls of the front end polyethylene winding structure wall pipe and the rear end polyethylene winding structure wall pipe, so that a closed annular air cavity is formed among the rubber sealing strip, the inner walls of the front end polyethylene winding structure wall pipe and the rear end polyethylene winding structure wall pipe, the side plates and the annular plates; and then, inflating the annular air cavity through an air inlet and outlet pipe by using an air pump, observing the air pressure value through a pressure gauge, and closing the valve when the air in the annular air cavity reaches a certain pressure. Continuously observing whether the pressure of the pressure gauge changes or not, and judging the tightness of the pipe connector. After the test is finished, the valve is opened to vent the gas in the annular gas cavity, then the gas of the two rubber sealing strips is released, so that the two rubber sealing strips are separated from the polyethylene winding structure wall pipeline, and the pipe connector gas-closing detection device is taken away. The volume of the annular air cavity is small, so that the inflation is fast, the time is saved, and the time and the labor are saved; and a closed water detection method for filling water into the annular air cavity can be adopted for detection, and water resources can be greatly saved during closed water detection.
Through the improvement, the defects in the prior art are overcome, and the novel pipe connector air-tight detection device is provided, and is convenient and rapid to detect.
