[0002] At present, the conventional pipeline connection adopts the flange connection method. The flange installation needs to occupy a large space, and it is necessary to leave enough construction space for the fastening of the thread; at the same time, the nut is removed during the entire connection process. In addition to the necessary workpieces such as bolts and bolts, other tools such as wrenches and screwdrivers are required, so the time required for its installation is also longer
Moreover, after working for a long time, the bolt material yields and creeps, which weakens the degree of tightening, so that the tightness of the connection is damaged, and it is not easy to repair; Chinese patent 201210109629.0 discloses a "pipeline quick-loading and quick-disconnecting connection assembly", but in use, its sealing effect is poor
