Description

Pipeline connecting device Technical Field The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection device. Background The quick butt joint mechanism of the water pipe is used as a device capable of realizing quick, convenient and reliable connection among the water pipes, wherein the cutting sleeve type quick butt joint mechanism is most common, and the working principle is that the cutting edge inside the cutting sleeve is driven to cut into the outer wall of the pipe by screwing the nut on the cutting sleeve, and the sealing gasket is synchronously extruded, so that the sealing and fixing effects are achieved. However, in the actual use process, various factors can influence the sealing gasket along with the continuous time, on one hand, the continuous pressure impact of water flow in the water pipe and the slight vibration of the pipe, etc. cause that the blade piece is always in contact with the outer wall of the pipe and is stressed, and then relative friction movement occurs, and long-time repeated friction is caused, so that the surfaces of the blade piece and the outer wall of the pipe become smoother, finally friction force between the blade piece and the outer wall of the pipe is reduced, on the other hand, the sealing gasket is in a pressed state for a long time, the elasticity in the sealing gasket is gradually weakened, permanent deformation to a certain extent also occurs, and the reaction force applied by the sealing gasket to the blade piece is reduced along with the change of the sealing gasket, so that the compression degree of the blade piece on the outer wall of the pipe is far less than that of the first installation, and accordingly, the friction force between the blade piece and the pipe is also reduced, and the joint clamped by the pipe is easy to fall off when the water pressure is too high, thereby reducing the reliability of the whole water pipe system, loosening, leakage and other problems frequently occur, and the butt joint mechanism which can normally use for a long time is easy to repeatedly occur, so that the problems are not easy to change, and the whole life cycle is not easy, and the life cycle is stable.
