Detailed Description
As shown in fig. 1-2, a water supply and drainage pipeline connecting and fixing device comprises a sleeve 1, a threaded pipe 11 is connected to the sleeve 1 through a thread, a sleeve 2 concentric with the sleeve 1 is fixed to one end of the sleeve 1, the sleeve 2 is fixedly and hermetically connected with the sleeve 1, one end of a pipeline 8 extends into the sleeve 1 after penetrating through the sleeve 2 and the sleeve 1, the sleeve 2 is welded to the pipeline 8, a sleeve ring 3 is sleeved on the sleeve 2, a plurality of blind holes 4 are uniformly distributed on the circumference of the outer edge of the sleeve ring 3, the sleeve ring 3 is connected to the sleeve 2 through a thread, a fixing ring 9 is fixed on the pipeline 8 in the sleeve 1, a rubber sleeve 12 is fixedly sleeved on the outer edge of the fixing ring 9, a top ring 5 is sleeved on the pipeline 8 between the fixing ring 9 and the sleeve 1, a plurality of ejector rods 6 are uniformly distributed and fixed on the circumference of the end face, facing the, the cover is equipped with connecting pipe 10 on the pipeline 8 in the sleeve 1, and connecting pipe 10 inner edge and rubber sleeve 12 sliding seal contact are fixed with conical rubber ring 7 on the terminal surface of apical ring 5 orientation connecting pipe 10, rubber ring 7 is the elasticity rubber ring, and rubber ring 7 inner edge and pipeline 8 outer fringe sliding seal contact have seted up conical surface 13 on connecting pipe 10 orientation rubber ring 7 one end, and the conical surface 13 sealing contact of rubber ring 7 outer fringe and its one side connecting pipe 10.
When installing pipeline 8, establish sleeve pipe 2 and sleeve 1 at 8 pot heads of pipeline that need connect, then make pipeline 8 run through sleeve 1, fixed ring 9 is fixed on pipeline 8, later, pulling sleeve pipe 2 and sleeve 1 for fixed ring 9 is located sleeve 1, then with sleeve pipe 8 and pipeline 8 fixed connection.
When two pipelines 8 are connected, two ends of a connecting pipe 10 are respectively sleeved on fixing rings 9 on the two pipelines 8, a rubber sleeve 12 is in sliding sealing contact with the inner edge of the connecting pipe 10, a pull rod is inserted into a blind hole 4 and then a lantern ring 3 is rotated, the lantern ring 3 is enabled to be close to a sleeve 1 on a sleeve 2, the lantern ring 3 enables a top ring 3 to drive a rubber ring 7 to be close to the connecting pipe 10 through a top rod 6, after the outer edge surface of the conical rubber ring 7 is in contact with a conical surface 13 of the connecting pipe 10, the lantern ring 3 is continuously screwed, under the guiding action of the upper conical surface of the connecting pipe 10, the pressure between the inner edge of the rubber ring 7 and the outer edge of the pipeline 8 is increased, the pressure between the outer edge surface of the rubber ring 7 and a conical surface 13 of the connecting pipe 10 is increased, at the moment, the pipeline 8 is in sealing connection with the connecting pipe 10, make rubber ring 7 have to the surplus of the direction motion of solid fixed ring 9 place, make things convenient for 7 inner edges of rubber ring and the outer fringe tightly to support conical surface 13 on pipeline 8 outer fringe and the connecting pipe 10, gu the rubber sleeve 12 of fixed ring 9 outer fringe can be further with connecting pipe 10 inner edge sealing connection simultaneously, the sealing performance of pipeline 8 connection fixing device has been increased, connecting pipe 10 has the movement surplus between sleeve 1 and pipeline 8, consequently, can compensate two pipeline 8 and connect, be applicable to the butt joint connection of the 8 ports of pipeline of different distances, pipeline 8 connects the back simultaneously, two sleeve 1 pass through screwed pipe 11 threaded connection, the stability performance of pipe connection fixing device has been increased.
