Rotary connection two-way detection device and method

Abstract

The invention discloses a rotary connection two-way joint detection device and method, and relates to the technical field of two-way joint detection, the rotary connection two-way joint detection device comprises a bearing plate, a supporting frame is fixed on the bearing plate, a sliding frame is fixedly connected with a limiting frame, and a straight pipe section is in threaded fit with a two-way joint. A first sealing assembly opposite to the end face of the two-way connector is installed on the limiting sleeve, and a second sealing assembly opposite to the annular abutting table is installed at the end, facing the two-way connector, of the straight pipe section. The double-shaft motor drives the adjusting assembly to drive the straight pipe section to rotate, and the straight pipe section is rotationally connected with the two-way connector in a threaded fit mode. According to the invention, the end face and the annular abutting table of the two-way joint are pressed and sealed at the same time, so that the two connecting ends of the two-way joint have a good sealing effect when a hydrostatic test operation is carried out, and the detection effect of the two-way joint is greatly improved.

Description

technical field [0001] The invention relates to the technical field of two-way joint detection, in particular to a rotary connection two-way detection device and method. Background technique [0002] A pipe joint is a part of a hydraulic system that connects pipelines or mounts pipelines on hydraulic components. For the connector, in the process of testing the two-way joint, it is necessary to pressurize the inside of the two-way joint, and the overall strength of the two-way joint is determined by the leakage. [0003] The Chinese patent with the authorization announcement number CN 215524937 U discloses a pipeline joint detection device, including a fixed plate, the top ends of the fixed plate are fixed with support brackets, and the upper ends of the two support brackets are fixed by a first connecting plate. A piston cylinder is sleeved, the bottoms of the two piston cylinders are connected with a detection tube, the other ends of the two detection tubes are connected w...

[0003] The Chinese patent with the authorized notification number CN 215524937 U discloses a pipe joint detection device, which includes a fixed plate, and the two ends of the top of the fixed plate are fixed with support frames, and the upper ends of the two support frames are fixed by the first connecting plate. Piston cylinders are sleeved, and the bottoms of the two piston cylinders are connected with detection tubes, and the other ends of the two detection tubes are connected with pipe joints, and the lower ends of the two support frames are sleeved with sleeves through the rotating mechanism. The top of the device is fixed with a placement groove, and the pipe joint is located in the placement groove; however, during the use of the device, it cannot effectively seal the end of the pipe connection components such as pipe joints and two-way joints, causing the two-way joints to be internally sealed. During pressurized detection, the pressurized water is easy to leak from the end of the two-way joint, which makes it impossible to detect whether there is a crack in the body of the two-way joint, and the detection operation is greatly restricted. A rotary connection two-way detection device and Method, to solve the above-mentioned existing technical problems
