Abstract
The utility model provides a fast movable joint for a pipe, composed of a joint body, an external pressure thread clamping member, a fastening ring, a washer, a spacing sleeve and sealing rings on both sides of the spacing sleeve. The utility model has the advantages of reliable sealing, pressurization, convenient installation, no need of processing the end of a pipe, and no need of holding the pipe. The utility model can also be used for pipe interfaces of valves and equipment, simplifying installation and maintenance.
Description
The utility model belongs to a kind of effective link.
The union that the connection of pipeline is adopted at present, its structure adopts the screw thread hitch mode that adapts with pipeline, is made up of two fittings bodies and sealing gasket and coupling nut, is processed with to be connected the screw thread that adapts with pipeline on the inwall of fittings body.Behind the screw thread of the processing of the pipe end of the pipeline that will connect and the mutual interlock of fittings body inner thread, twine fiber crops, japanning during installation, then fittings body be tightened in respectively take over the end on, and must hold pipeline and prevent its rotation, at last sealing gasket is arranged between two fittings bodies and connects and step up with coupling nut.So, tighter to installation requirement again when this union is taken a lot of work when as installed, and because pipe end is processed with screw thread and attenuation, so it installs and uses the life-span, and quite the pipeline section at other positions is low.This brings the consumption of bigger constant and unhelpful human and material resources to maintenance.
At above-mentioned situation, it is easy that the purpose of this utility model provides a kind of installation and maintenance, do not need the pipe end machining screw is also sealed reliable and withstand voltage, and working life also high quick movable pipe joint.
Quick movable pipe joint provided by the utility model to achieve these goals steps up part by fittings body spacer, seal ring, packing ring, retaining ring and external pressure screw thread and is formed.
The description of the drawings:
Accompanying drawing 1 is the structure cut-away view of general type of the present utility model;
Accompanying drawing 2 is end views of retaining ring;
Accompanying drawing 3 is one of embodiment of the present utility model structural drawing;
Accompanying drawing 4 is two structural drawing of embodiment of the present utility model;
Accompanying drawing 5 is three structural drawing of embodiment of the present utility model;
The utility model is according to Fig. 1. Fig. 2, structure, fast movable joint for pipe comprises that fittings body (1), dead ring ((2), (8)), sealing ring ((3), (5)), spacer (4), packing ring (6) and external pressure screw thread add The parts such as tight part (7). Wherein sealing ring (3) and sealing ring (5) are arranged on the both sides of spacer (4), the outside of sealing ring (3) is provided with dead ring (2), the outer wall of dead ring (2) reaches with it, and the inwall of contacted fittings body (1) is conical surface, be provided with packing ring (6) and dead ring (8) in the outside of sealing ring (5), the outer wall of dead ring (8) and with it the contacted external pressure screw thread inwall that steps up part (7) be conical surface, fittings body (1) steps up part (7) to be threaded with the external pressure screw thread, has flexible dead ring (2) and dead ring (8) has breach.
During use, will be fittings body (1), dead ring (2), sealing ring (3) and spacer (4) are enclosed within on the pipeline (9), to step up part (7) to the external pressure screw thread, dead ring (8), packing ring (6) and sealing ring (5) are enclosed within on the pipeline (10), to and spacer (4) be moved in the middle of the port of pipeline (9) and pipeline (10) the axial alignment of pipeline (9) and pipeline 10 then, make the end of pipeline (9) and pipeline (10) be inserted into the inside of spacer (4), to rely on all parts the two ends of spacer (4) again, will step up part (7) to the external pressure screw thread at last and be screwed to fittings body (1) upward and tighten connection and the sealing of just finishing pipeline. This moment, sealing ring (3) and sealing ring (5) were subjected to axial pressure and axial shrinkage, cause that simultaneously radially Peng inner surface that makes sealing ring (3) and sealing ring (5) that rises is attached on the outer surface of pipeline (9) and pipeline (10) tightly, thus the sealing of the system of realization. Having is simultaneously radially contractd under the force action of the bounce that flexible dead ring (2) is subjected to the pressure of joint (1) and sealing ring (3) tightly embraces the outer surface of pipeline (9), be subjected to radially being contractd under the force action of reaction force that the external pressure screw thread steps up the pressure of part (7) and packing ring (6) and tightly embrace the outer surface of pipeline (10) and have flexible dead ring (8), thereby realize fastening purpose. The sealing effectiveness of system and fastening force step up tightening of part along with the external pressure screw thread and are strengthened.
One of embodiment of the present utility model;
According to quick movable pipe joint shown in Figure 3, the end face of the both ends of the surface of spacer (13) and contacted with it seal ring (12) and (14) is conical surface, sets up packing ring (11) between seal ring (12) and retaining ring (2).It is to bring into play to greatest extent impacting force and increase substantially its voltage endurance capability that such structure can make.
Embodiment's of the present utility model two;
According to the quick movable pipe joint of figure shown in (4), fittings body (19) is a reducer, and its inwall is stepped shaft cylinder curved surface, and the outer wall two ends are processed with respectively with the external pressure screw thread and step up be connected with (7) screw thread of usefulness of part (15).
Embodiment's of the present utility model three;
According to the quick movable pipe joint shown in the figure (5), on one section inwall of fittings body (21) and be attached thereto on the outer wall that the external pressure screw thread that connects steps up part (22) and be processed with screw thread, the inwall that steps up part (22) with the contacted external pressure screw thread of the outer wall of retaining ring (8) is conical surface.
The needs that the utility model connects according to the pipeline of different spatial can be designed Loose joint bend, threeway, many series product such as logical, also can use on the pipe interface of various valves and equipment.
The quick movable pipe joint that the utility model provides according to said structure does not need any processing to pipeline when practical application, and to the connection of coarse table pipeline, its advantage is more outstanding.
Claims (4)
1, a kind of quick movable pipe joint, it is characterized in that comprising that fittings body, spacer, seal ring, packing ring and external pressure screw thread step up part, wherein spacer (4) is arranged between seal ring (3) and the seal ring (5), and packing ring (6) is arranged between seal ring (5) and the retaining ring (8);
