The invention discloses a pipeline air-tightness detection device, and relates to the technical field of pipeline detection equipment. The pipeline air-tightness detection device comprises at least amain body and two inflatable sealing rings, two sealing ring accommodating grooves are annularly formed in the outer wall of the main body in the circumferential direction, the inflatable sealing rings sleeve the corresponding sealing ring accommodating grooves, an inner cavity of the main body is separated into a sealing ring pressurized cavity, a test pressurized cavity and an air channel accommodating cavity through partition plates, and the two inflatable sealing rings communicate with the sealing ring pressurized cavity; a pressurized test hole is formed in the side wall of the main body;and the air channel accommodating cavity communicates with the external atmospheric pressure, the air channel accommodating cavity is internally provided with a test air channel, and the test air channel comprises a sealing ring inflatable opening and closing air cylinder used for inflating and pressurizing the sealing ring pressurized cavity and a test pressurized opening and closing air cylinder used for inflating and pressurizing the test pressurized cavity. The pipeline air-tightness detection device with high efficiency and high precision and incapable of damaging pipe fittings is provided.
Description
technical field [0001] The invention relates to the technical field of pipeline detection equipment, in particular to a pipeline airtightness detection device. Background technique [0002] In the construction process of oil pipeline network, gas pipeline network or water conservancy pipeline network, due to the limited length of a single pipe fitting, in order to realize the long-distance transportation of fluid, it is often necessary to butt the ends of multiple pipe fittings to increase the length of the pipeline. However, during the docking process of the pipe fittings, due to improper operation by the operator or the influence of the surrounding environment and other factors, the pipe fittings may leak at the butt joint. Therefore, after the pipe fittings are docked, an air tightness test is required. [0003] The existing pipeline airtightness detection method is usually to seal the first and last ends of the butted pipeline, inflate and pressurize the inner cavity, an...
