Abstract
The utility model relates to a movable joint for a pipeline, which comprises a joint body, a pressing cover, a filler, a pressing ring, etc., wherein, a telescopic cavity is arranged in the joint body; the part of the telescopic cavity, which is adjacent to an end opening, is provided with a sealing slot, and the filler and the pressing ring are filled into the sealing slot. The utility model plays the role of sealing by the pressure of the pressing cover to the pressing ring and the filler which is enabled to be deformed. The utility model has the advantages of convenient assembly and disassembly, and simple manufacturing technique. A pipeline has a certain telescopic distance in the telescopic cavity, and thereby, relatively greater errors are allowed to exist in the length and the installing angle of the pipeline.
Description
The utility model relates to the union that a kind of pipeline is used.
In the fitment process of various pipelines, in order to simplify working process, convenient finishing generally adopts union to come connecting tube.A flat mouthful Butt sealing is adopted in existing union, and inconvenience is installed, and cutting stock precision height when requiring to install.Inaccurate or the variation of duct length and angle can make installation very difficult and easy water clock and damage in blanking owing to reasons such as temperature variation cause.Patent application CN2073523U discloses a kind of pipe joint that comprises fittings body, compressing member, Sealing etc., utilizes the distortion of Sealing to seal, and it is easy to have loading and unloading, makes characteristic of simple, but requires still higher to the pipeline cutting stock precision of installing.
The purpose of this utility model provides a kind of simple in structure, and is easy to loading and unloading and can allow connecting tube length that pipeline union than mistake is arranged.
Purpose is achieved in that the utility model is made up of fittings body, gland, filler, trim ring, and an end of fittings body has screw thread or flange plate, and the other end has telescopic cavity, telescopic cavity by port section seal groove is arranged, insert filler and trim ring in the seal groove.
The utility model utilizes gland to trim ring and filler pressurization, makes filler produce deformation, with the gap between closed conduit and the fittings body, makes pipeline that bigger flexible scope is arranged in telescopic cavity like this; Because gland does not directly contact with filler, thereby avoids damaging filler; Owing to have the gap between telescopic cavity and the pipeline, make this union allow the error of several angle when mounted.The utility model is easy to loading and unloading, and accuracy of manufacturing is less demanding, and technology is simple, is a kind of pipe joint preferably.
Fig. 1 is an a kind of embodiment's of the present utility model positive view.
Fig. 2 is the structural drawing of collar 8.
Fig. 3 is an another kind of embodiment's of the present utility model positive view.
As shown in Figure 1, telescopic cavity 2 is arranged in fittings body 1, gland 9 and fittings body are with being threaded.During installation pipeline is inserted in the telescopic cavity, insert filler 4, trim ring 5, filler 6, trim ring 7 and collar 8 in the seal groove 3 successively, last gland.Collar 8 structures are seen Fig. 2, during last gland, and filler 4,6 distortion under trim ring 5,7 compressings, the gap between SEALING FITTING body and the pipeline, radial contraction, fastening pipeline and fittings body take place in collar 8 simultaneously.Wherein filler 4,6 can adopt plastics, rubber, spunyarn, asbestos etc. according to the field of employment difference.If outer diameter tube is D, then footpath, chamber d greater than D2-4mm, seals the vallecular cavity footpath greater than D8-12mm.Collar two exterior angle chamferings and gland female cone angle are the 50-60 degree.The seal groove bottom is an arc among the figure, can improve the stressing conditions of filler in seal groove, makes sealing effect better.The pipeline of the fittings body the other end and fittings body are with being threaded.
For the bigger pipeline of diameter, gland can be connected with screw rod with fittings body, and its structure as shown in Figure 3.
If be used in the high pressure pipe line, engrave annular ditch groove in the part that stretches into seal groove of pipeline, can make the higher pressure of connection tolerance of the present utility model.
Claims (5)
1, a kind of pipeline union, comprise fittings body 1, gland 9, an end of fittings body has screw thread or flange plate, it is characterized in that the other end of fittings body has telescopic cavity 2, telescopic cavity by port section seal groove 3 is arranged, be filled with filler 4,6 and trim ring 5,7 in the seal groove.
2, by the described pipe joint of claim 1, it is characterized in that being provided with between trim ring and the gland collar 8.
3, by the described pipe joint of claim 1, it is characterized in that being filled with alternately in the seal groove two layers of filler and two trim rings.
4,, it is characterized in that the seal groove bottom is circular arc by the described pipe joint of claim 1.
