Abstract
The utility model relates to a portable and movable joint for pipelines. The utility model has the structure that one end of a movable joint sleeve pipe is provided with an inner screw thread which is connected to one end of a screw thread arranged on a pipeline, the other end of the movable joint sleeve pipe is provided with an outer screw thread which is connected to a movable joint sleeve cover, a wedge-shaped rubber sealing ring is arranged between the connection of the movable joint sleeve pipe and the movable joint sleeve cover, and one end of the pipeline is inserted into a hole arranged on the other end of the movable joint sleeve pipe. The utility model has the advantages of simple connection way, flexible installation and operation, convenient operation, labor saving, time saving and enhanced efficiency of installation and maintenance work, and besides, the utility model is favorable for disassembly and suitable for the installation and the connection of pipelines, valves and pipe pieces.
Description
The utility model relates to a kind of pipe joint or pipe fitting, and particularly a kind of pipeline makes things convenient for movable joint.
There are a lot of problems in the 15mm-50mm pipeline movable joint that adopts in installation and maintenance dismounting at present: after the movable joint attaching nut takes apart, can not movable joint be removed at once and change, because movable joint Butt sealing place does not have the gap, pipeline can't be dismantled, have to take the way that links closely, pull and prize, take apart at the place with the movable joint Butt sealing, but be easy to damage pipe fitting and pipeline.Particularly in well or the narrow place of work surface change pipeline, during the valve pipe fitting, pipeline must be cut off a place, otherwise dismounting is not got off.During installation, must take to move back button or add way such as movable joint, take a lot of work, time-consuming, very inconvenient, working efficiency is not high.
Therefore, for overcoming the problems referred to above, the present invention has designed a kind of pipeline and has made things convenient for movable joint, and this movable joint is used for connecting pipe, and valve pipe fitting etc., connecting mode are simple, are beneficial to dismounting, installs, use flexibly, convenient, laborsaving save time, improve install and maintenance work efficient.
The purpose of this utility model provides a kind of a kind of pipeline that is beneficial to piping erection dismounting maintenance and makes things convenient for movable joint.
The utility model is to adopt such method to realize: it is to adopt the end on movable joint quill to have internal thread that pipeline makes things convenient for movable joint, be connected with screw thread one end on the pipeline (outside thread be connected with valve, pipe fitting can replace to silk with) have outside thread at the other end of movable joint quill, be connected with the movable joint upper shield, movable joint quill with have a wedge-shaped rubber seal ring between the movable joint upper shield is connected, go into an end of pipeline in another stomidium interpolation of movable joint quill, have the sphere of activities that pipeline (after pulling down sleeve pipe) has 20mm at least.
When movable joint is installed in the pipeline butt joint, wherein on place's pipeline without threading, movable joint upper shield and sealing rubber ring, movable joint quill are enclosed within on the threadless pipeline, pipeline inserts 3/4 place in the movable joint quill, be not less than 10mm apart from the sleeve pipe internal thread, the internal thread of movable joint quill is connected (outside thread is connected on valve or the pipe fitting) on threaded pipeline or the pipe fitting.This moment, pipeline was in 1/2 place in the sleeve pipe, and pipeline is not less than 20mm apart from the sleeve pipe internal thread, so that pipeline is flexible in sleeve pipe when removing.With movable joint upper shield, wedge-shaped rubber circle movable joint quill and pipeline space are sealed, when maintenance is removed, dismantle movable joint upper shield and seal ring, dismantle at the movable joint quill that will be connected on pipeline or the valve pipe fitting, and be enclosed within on the threadless pipeline the promptly dismountable pipeline of changing, valve or pipe fitting etc.
The utility model compared with the prior art, it is simple to have a connecting mode, is beneficial to dismounting, installs, use flexibly, convenient, laborsaving saves time, improves install and maintenance work efficient, and be applicable to that the installation of pipeline, valve and pipe fitting connects.
Concrete structure of the present utility model and embodiment are provided by the following drawings.
Accompanying drawing has been described the general structure generalized section that a kind of pipeline makes things convenient for movable joint.
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.
See shown in the accompanying drawing: it is to adopt the end on movable joint quill 1 to have internal thread that pipeline makes things convenient for movable joint, (outside thread is connected with valve, pipe fitting and can replaces silk is used) is connected with screw thread one end on the pipeline 4, the other end at movable joint quill 1 has outside thread, be connected with movable joint upper shield 2, movable joint quill 1 with have a wedge-shaped rubber seal ring 3 between movable joint upper shield 2 is connected, go into an end of pipeline 5 in another stomidium interpolation of movable joint quill 1, have after pipeline 5(pulls down sleeve pipe) have 20 centimetres the sphere of activities at least.
Connection and sealing means thereof that this method adopts can anti-8 kilograms of pressure.
The wedge-shaped rubber internal diameter of the seal ring is less than outer diameter tube.
When movable joint is installed in the pipeline butt joint, wherein on place's pipeline 5 without threading, movable joint upper shield 2 and sealing rubber ring 3, movable joint quill are overlapped 1 on threadless pipeline 5, pipeline 5 inserts 3/4 place in movable joint cover 1 pipe, be not less than 10mm apart from the sleeve pipe internal thread, the internal thread of movable joint is connected (outside thread is connected on valve or the pipe fitting) on threaded pipeline 4 or the pipe fitting.This moment, pipeline 5 was in 1/2 place in the sleeve pipe 1, and pipeline 5 is not less than 20mm apart from the sleeve pipe internal thread, so that pipeline stretches sleeve pipe 1 in when removing.With movable joint upper shield 2, wedge-shaped rubber circle 3 movable joint quill 1 and pipeline space are sealed, when maintenance is removed, dismantle movable joint upper shield 1 and seal ring 3, dismantle at the movable joint quill 1 that will be connected on pipeline or the valve pipe fitting, and be enclosed within on the threadless pipeline 5 the promptly dismountable pipeline of changing, valve or pipe fitting etc.
Claims (2)
1, a kind of pipeline makes things convenient for movable joint, it has pipeline 4, nut, outer sleeve and constitutes, it is characterized in that: the end on movable joint quill 1 has internal thread, be connected with screw thread one end on the pipeline 4, the other end at movable joint quill 1 has outside thread, be connected with movable joint upper shield 2, movable joint quill 2 with have a wedge-shaped rubber seal ring 3 between movable joint upper shield 1 is connected, go into an end of pipeline 5 in another stomidium interpolation of movable joint quill 1.
