Description
Technical field
A kind of flange being connected with pipeline is the utility model is related to, more particularly relates to one kind high polymer material system
Into new socket joint flange.
Background technology
Flange is the conventional attachment structure of pipeline connection, and wherein socket joint tubular type connection is again a kind of common flange connection side
Formula.
Bell-and-spigot pipe is divided into rigid socket joint connection and connects two kinds with flexible socket joint.Rigid socket joint connection is inserted with the socket of pipeline
Enter in the bellmouth of pipeline, caulking material filleting is first used after contraposition, is then sealed with encapsulant, make a firm envelope
Close.Flexible socket joint jointing is only put into flexible rubber ring pipeline socket in sealing, and then force will pipe
Sub- spigot insertion, forms a sealed tube for adapting to a range of displacement and vibration.
Application number：201110388265.X Authorization Notice No. CN 102494210 B, entitled：In " bump joint "
State's patent of invention discloses a kind of flange：" it includes two fittings bodies, two flange bodies, a sealing ring；Described two joints
