Abstract
The utility model relates to a pipeline engineering coupling, which is composed of an inner sleeve pipe and an outer sleeve pipe. The utility model is characterized in that the inner sleeve pipe and the outer sleeve pipe form a spiral sleeved coupling; a telescopic sealing ring and a pressing nut are arranged between the inner sleeve pipe and the outer sleeve pipe; the outer coupling ends of the inner sleeve pipe and the outer sleeve pipe are tapped with inner threads. The utility model has the advantages of compact structure, simple structure, high coupling speed and high efficiency, especially in the pipe installation and the repair of the pipeline, the utility model is not influenced by a fixed pipe network; the movable joint can be conveniently moved without wrenching other components; some space is left for the convenience of changing and installing the pipe fittings, such as a gate valve, etc. The utility model can be suitable for serving as the movable joint in various pipelines.
Description
The utility model belongs to the pipe coupling class.
At present, being connected between the pipeline that people use always and pipeline, pipeline and the valve is to adopt the simplest tube coupling head, its maximum shortcoming be pipeline fix or closed duct in, be difficult for mounting or dismounting, must pull open pipeline or sawed-off pipeline just can be finished mounting or dismounting.
The purpose of this utility model is that a kind of telescopic movable joint will be provided, so that in various piping erection and maintenance, be not subjected to its pipe network to fix dead or closed circuit influence, need not pull other pipe fitting or sawed-off pipeline, can shift out this movable joint easily, slot milling is convenient to change and installation and maintenance.
Concrete scheme of the present utility model is: design a pair of inside and outside sleeve pipe, both connect for thread set, and between is equipped with elastic seal ring and gland nut; The external connection end of inside and outside sleeve pipe is all attacked interior spiral shell.
During installation, the intake pipe with in the external connection end tipping pipeline of inner sleeve of the present utility model revolves and stretches outer sleeve attaching outlet pipe or valve pipe fitting, screws gland nut and makes the seal ring sealing.
Because the utility model is when unscrewing, can shorten simultaneously, so in the piping erection maintenance, not fixed or the influence of closed circuit structure by its pipe network, need not pull other pipe fitting or sawed-off pipeline, can conveniently shift out this movable joint, slot milling is convenient to replacing and installation and maintenance.This movable joint novel structure, installation and maintenance are efficient and convenient.
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a perspective view of the present utility model.
Embodiment: referring to accompanying drawing, make inner sleeve 4 and outer sleeve 1 and gland nut 3 by figure, the gland nut 3 of on inner sleeve, packing into successively, seal ring 2 and outer sleeve are finished product.
