Description
Technical field
The utility model relates to field of mechanical technique more particularly to a kind of assembling pipe joints.
Background technique
In pipeline engineering construction, different connection methods should be selected according to the material of pipe used.Common steel tube has spiral shell
Line connection, welding are connected with ring flange；Seamless steel pipe, non-ferrous metal and stainless steel tube are mostly welding and flanged joint；Cast iron pipe
Socket joint is mostly used to connect, minority uses flanged joint；Plastic tube mostly uses threaded connection, bonding and hot-melt adhesive paste etc., other are non-
There are many forms again for metal tube connection.Pipeline connection at present is substantially that small diameter pipeline mostly uses screwed connection mode to realize nothing
Leakage sealed connection, large-scale pipeline is using welding or flanged joint.
Pipe screw thread is connected with that cylindrical female is inserted in cylindrical external thread, cylindrical female is inserted in the outer spiral shell of cone
Line and conical internal threads are inserted in three kinds of modes of Conical external threads.Wherein taper thread connects, and is common connection type.
When tightness and maintenance in order to increase gas pipe thread interface not reason screw-thread rust cause it is not easy to disassemble, at screw thread
It generally wants filled.Therefore filler wants that gap and anticorrosion can be filled.To guarantee that interface is tight for a long time, gas pipe thread is not
It is too loose, it cannot prevent from leaking with packing material is added.It should be noted that filler can only be used once in threaded connection, if meeting
Disassembly, should re-replace.
Suitable pipe vice should be selected by tightening pipe screw thread.It mustn't be twisted by the way of cylinder jacketed on the handle in pipe vice
Tight pipe.After pipe screw thread is tightened, 1~2 button screw thread (i.e. screw thread tail) should be exposed outside in pipe fitting or valve member.Screw thread cannot all be twisted
Enter, preservative treatment should be cleaned out and be done to extra flax silk, when upper pipe fitting, it should be noted that the position and direction of pipe fitting can not fall to twist.
Flanged joint is exactly two pipelines, pipe fitting or equipment.It is first individually fixed on a ring flange, then at two
Flange gasket is added between ring flange, and it is dismountable that two ring flanges are finally tensed to the one kind for making it combine closely with bolt
Connector.
This connection is mainly used for the connection of cast iron pipe, rubber-lined pipe, non-ferrous metal pipe and flange valve etc., process equipment with
The connection of flange also all uses flanged joint.
The position that the flanged joint of steel pipe needs to dismantle is related with the flanged (FLGD) valve member of connection, equipment, instrument etc..Flange
There are cast iron and two kinds of steel.Flange and pipeline are connected with flange pine set, threaded connection, are welded to connect three kinds, in Pipe installing
The connection type of multi-purpose downhand welding steel flange.
Flange connection.Flange loose flange is generally used for the pipeline of the similar material such as copper pipe, lead pipe, plastic tube, turns over
According to the operating method that different material selections is different when side, flange requirement is smooth, must not there is breach and fold.
Screwed flange connection, is connected with internal thread ring flange with there is externally threaded steel pipe, and this flange is mostly to cast
Iron material matter can be used for the connection of low pressure pipeline.
Using being welded to connect, this flanged joint is widely used for welded flange connection, flange and steel pipe.Its welding method
Be: choosing a pair of of flange, be attached separately to connect two pipe ends, if any equipment had flange, then select the method for same specification
Orchid covers wait cause, and first spot welding a bit, corrects verticality, finally that flange is secured with tube welding.The inside and outside two sides of slip-on welding flange
All necessary and tube welding.The characteristics of connection: interface is securely tight, and weld strength commonly reaches 85% of pipe strength or more,
Even more than strength of parent.Welded connecting is directly connected between pipeline section, and simple structure, pipeline is beautiful and tidy, is saved a large amount of
Sizing pipe fitting.Interface is tight, does not have to filler, can reduce maintenance work.Interface is not limited by caliber, and operating speed is fast.Welding
Connecting interface is fixed interface, and connection, disassembly are difficult, if you need to overhaul, clear up pipeline then for pipe cutting.Metal tube welding:
It is welded to connect docking, welded flange and other flexible spouts for being mainly used for water supply steel tube.The method of welding usually has gas welding, craft
Electric welding and automatic arc welding, Contact welding etc..Pipeline should carry out comprehensive dress watch before welding.
When steel pipe aligning, the gate of a village of longitudinal seam should mutually stagger 100mm arc length or more, must not there is cross weld seam；Weld bond
It must not be placed in the wall of building, structures etc..
When plate rolling tube, the longitudinal seam of every section pipe cannot be arranged on the same line, the longitudinal direction of two section adjacent pipes
The distance between weld seam should be greater than 3 times of wall thickness, and be not less than 100mm；Two adjacent longitudinal seam spacing are not on same section pipe
It should be less than 300mm.Pipe bending position must not have weld seam, and butt weld cannot be less than the outer diameter of pipe apart from inflection point, and not
Less than 100mm (except weld ell).There should not be circular weld at support of pipelines.
Existing groove packing seal attachment device is mainly used for the connection of building fire-fighting pipeline, which needs in pipe
Road end edge, which extrudes one of groove, to be come, this groove is for fixed connection apparatus and puts airtight and watertight padding.Other pipeline connection sides
Method does not just repeat one by one herein, each versatility of existing pipeline connection technology is not very strong or is only applicable to small in a word
Caliber pipe or medium-sized or large-diameter pipeline connection is only adapted to, the connection of metallic conduit can only be perhaps adapted to or is only fitted
Nonmetal pipeline etc. is answered, it is not pressure-resistant enough that perhaps there is also connection types, and connection type is cumbersome time-consuming or connection type cost
High factors, many assembling pipe joints are not used as telescopic joint, existing telescopic joint accessory substantially use bellows or
It is bent expansion fashion.
Therefore, it is necessary to provide the new assembling pipe joint of one kind to solve the above technical problems.
