Abstract
The utility model relates to a telescopic joint for a pipeline, which belongs to a pipeline jointing element. The inner part of a telescopic pipe sleeve is provided with a section of telescopic pipe capable of sliding axially; one end of the telescopic pipe sleeve is provided with threads, and the other end is in fit with a press cap; an outer casing of the telescopic pipe is in fit with the press cap and extends out of the press cap, and the outer end of the outer casing is provided with external threads. When the utility model is arranged, both ends of the pipeline being connected are respectively connected with both ends of the telescopic joint; when necessary, the telescopic pipe sleeve can be directly used as a pipeline joint. The design solves the disadvantage that the length of a connecting member is fixed existed in the existing pipeline connection technique, and the utility model has the advantages of convenient pipeline connection in the processes of installation and maintenance, simple structure, easy operation and high work efficiency.
Description
The utility model belongs to a kind of pipe connecting part, is widely used in being connected of Chemical Manufacture and liquid-transport pipe-lines such as tap water.
At present when installation and service conduits, basically adopt the active joint pipeline Placement of (claiming the friendship joint again), because the stationarity of pipeline, the problem of bringing is that the distance between connected pipe ends must be controlled in the margin of error of 3mm, this brings sizable difficulty in operation, become the disadvantage in the pipeline connection technology.
The pipe coupling that provides a kind of length to stretch just is provided the purpose of this utility model, thereby solves problems of the prior art.
The design's pipeline expansion joint, be to conceive like this: the inside at flexible pipe box is provided with one section telescopic pipe that can slide vertically, and an end of flexible pipe box is shaped on internal thread, and it can be connected with an end of connected pipe.The other end cooperates with clamping cap by internal and external screw thread, and the clamping cap center is a circular hole, and the end of clamping cap is provided with a seal ring, with shoulder in the flexible pipe box every matching.The shell of telescopic pipe cooperates with clamping cap, and can endwisely slip along the center hole of clamping cap.The outer end of telescopic pipe is shaped on outside thread, is used for and being connected of the connected pipe the other end.
Use this pipeline expansion joint, pipeline is easy to connect in installing, overhauling, and simple in structure, and easy operating can be increased work efficiency greatly.
Below in conjunction with accompanying drawing the utility model is further described, and provides the embodiment of present design:
Fig. 1 is a pipeline expansion joint structural drawing:
One section telescopic pipe 9 is arranged in flexible pipe box 2, and the left end of flexible pipe box 2 is made internal thread 1, and internal thread 1 afterbody is made shoulder every 3.The right-hand member of flexible pipe box 2 and clamping cap 8 match by internal and external screw thread, and establish a rubber seal 6 at the inner top of clamping cap 8, and the shoulder interior with flexible pipe box 2 cooperates every 5.Telescopic pipe 9 stretches out outside the clamping cap 8, and cooperates with clamping cap 8.Fin 4 is made in the inner of telescopic pipe 9, and is excessive to prevent liquid in pipe pressure, the pipe box 2 of deviating to stretch, and shell is shaped on outside thread 10.During installation, the two ends of connected pipe are connected with the left end of flexible pipe box 2 and the right-hand member of telescopic pipe 9 respectively.In the occasion of necessity, flexible pipe box 2 can directly connect as pipeline, as the telescopic pipe in the utility model 9 is removed, also can work as ordinary couplings and use, and has the effect that improves work efficiency.
