Description
Technical field
The present invention relates to the connection of delivery pipe, more particularly, to the attachment structure between delivery pipe and conveying tube joint.
Background technology
Connection between traditional delivery pipe and conveying tube joint is typically using butt welding or directly in delivery pipe and pipe
Welding flange connects on joint.Butt welding is cumbersome, cost is high, maintenance when need destroy cutting.In the past, in delivery pipe
And on pipe joint during the connection of welding flange, the traditional connected mode of steel pipe is first to do groove in steel tube head portion to fall
Angle, is then welded and fixed a piece of ring flange again, and the termination part of joint also obtains groove chamfering and is welded and fixed a piece of ring flange, rubber again
Glue sealing ring is placed between two flange plates, then is locked two panels ring flange with bolt.If using butt welding or its
The connection of his non-dismountable formula, it is difficult to carry out that the anti-corrosion treatment to tube wall, which is, while welding slag etc also can not be located
Reason.The traditional connected mode of plastic conduit be before plastic pipe welding on be first inserted in a ring flange, then by the method for being inserted in
The tubing end head of blue disk is with a plastics flange connector to being welded into flange-interface.Same pipe fitting with before flange connector,
Butt welding welding before ring flange also must be first inserted in end socket of pipe fitting portion, then by end socket of pipe fitting portion with plastics flange connector to being welded into
Flange-interface, is put into rubber seal between two flange connectors, then with bolt by two panels ring flange lock sealing.
Traditional connected mode requires that the outside dimension of integral (type) flange disk is larger, more than connection more than tube outer diameter 100mm,
Working face position can not meet installation requirement, cause installation connection difficult.And pipe part and ring flange butt welding must be connected
Connect, cost is high, work efficiency is low, and welding requirements is high, does not allow welding dislocation, deflection, telescopic moving poor, it is impossible to which adaptation is drawn by the external world
Rise and various change in location occur, be also easy to produce fracture, also unfavorable maintenance.Shortcoming be weld bond at the construction field (site) can not admittedly molten, pickling and
Passivation, that is to say, that Crater antiseptic, just since weld bond, the weld bond of welding gets rusty easily for corrosion in the future.
The content of the invention

One clamping face, the bellmouth for clamping face place gasket seal, and delivery pipe is connected by boss flange gland by bolt with pipe joint,
Boss flange gland and pipe coupling flange the bellmouth end face is provided with bolt hole.
The delivery pipe can set flange socket joint end structure, and the flange can be individual layer flange, double flare or three layers of flange.
The delivery pipe flange bell end can be clamped in pipe joint female end groove.
The clamping face of the pipe coupling flange female end can be provided with seal groove, and seal groove is provided with gasket seal.
Gasket seal can be provided between the clamping face of the delivery pipe bell end and pipe joint female end.
Internal pressure convex surface ring bar can be provided with the compressive plane of the boss flange gland.
The boss flange gland can use split type or monoblock type.
Bolt hole can be provided with the boss flange gland, the bolt hole can use circular hole or square opening, by pipe diameter size
Difference, the fastening bolt on boss flange gland can be provided with 4 holes, 6 holes and 8 holes etc..
The pipe joint can use threeway, reducer tee, four-way, reducing cross, 90 ° of elbows, 90 ° of elbows of reducing, 45 ° it is curved
Head, straight coupling, reducing joint or loose joint are first-class.
The delivery pipe can use metallic object, non-metallic body or metal and non-metal composite.
Compared with the prior art, the invention has the advantages that：
The present invention is using the substitution welded flange connection of pipe coupling flange bellmouth end face connected mode, so as to overcome existing skill
The defects of art, have be connected firmly, pressure-bearing is high, does not produce secondary pollution, good seal performance to water quality, is not easy to pull, convenient inspection
The advantages that repairing.
