Description
Technical field
Utility model relates to vacuum insulation technical field of pipeline connection, especially a kind of vacuum heat-insulated pipe scabbard formula insertion connector.
Background technology
In existing technology, the plug-in type coupling that vacuum heat-insulated pipe uses, the basic inserting mode using yin, yang plug.Different places is, some technology use deformation difference produced by the shrinkage factor that different materials is different under low-temperature deep operating mode to carry out physical seal, and some technology use the mode of yin, yang plug inner face axial seal to seal.
In both sealing means, first kind of way proposes high requirement to the selection of material and the processing of the cooperation face of sealing material, through welding fabrication, connection-peg parts also to ensure that high-precision concentricity requirement is to reach final fitted seal requirement, greatly improve difficulty of processing, simultaneously, special undeformed metal material is with high costs, and manufacturing cost is high.These parts be machined out and welding operation produce deformation and duty under catch a cold produce stress influence cause yin, yang plug grafting difficulty, sealing surface cannot ensure to fully seal and cause leakage, cold draining.The manufacture of this connector necessarily causes not having between different yin, yang connection-pegs interchangeability, maintainable extreme difference.
The second yin, yang plug uses the design of inner face axial seal structure, determine the sealing surface that this sealing structure cannot provide permanently effective, lack the sealing structure of low temp compensating after seal is in work half a year or 1 year, follow the string and cause seal failure, gradually produce leakage cold draining, whole vacuum pipe system is caused to lose efficacy, it is impossible to normally to work.And the maintainable extreme difference of axial end surface seal structure.
Summary of the invention
Connecting weak effect, the deficiency of maintainability difference to overcome existing vacuum insulation to connect pipeline, utility model provides a kind of vacuum heat-insulated pipe scabbard formula insertion connector.
Utility model solves its technical problem and be the technical scheme is that a kind of vacuum heat-insulated pipe scabbard formula insertion connector, including convex plug and cloudy plug, described convex plug includes inner tube one, outer tube one and outer tube two it is provided with outside said inner tube one, described outer tube one is provided with flange one, described outer tube two one end is connected with flange one, described outer tube one one end is provided with plug, described cloudy plug includes inner tube two, flange two and outer tube three it is provided with outside said inner tube two, described outer tube three one end is connected with flange two, said inner tube two one end is provided with connector assembly, it is provided with O between described flange one and flange two, described flange one and flange two both sides are provided with binder, described plug is provided with memory sealing ring.
According to another embodiment of utility model, farther including, said inner tube one and inner tube two liang are terminated with inner connecting tube, described outer tube two and outer tube three liang and are terminated with extension tube attached.
According to another embodiment of utility model, farther including, described convex plug and cloudy plug use insulating materials manufacture.
Utility model provides the benefit that, this vacuum heat-insulated pipe scabbard formula insertion connector is mainly used in low-temperature deep liquid conducting pipes, by scabbard formula socket connection method of the present utility model, for vacuum heat-insulated pipe at curstomer's site, use the connection of simple tool, it is not necessary to Site Welding.Vacuum pipe after connection can accomplish that whole piece pipeline reaches whole vacuum thermal insulation.
Particularity due to the conveying of low-temperature deep liquid, pipeline needs to use the two-layer equation insulation construction of vacuum heat-insulated pipe, joint connection in site for double-layered vacuum heat-insulation pipeline proposes special requirement, should confirm that whole segment pipe, all under vacuum heat-preserving state, have to be accomplished in junction again to reliably seal and without cold draining.The structure of double-layer vacuum protection is not destroyed to maintain the integral heat insulation performance of vacuum pipe in i.e. junction.Meanwhile, it is also contemplated that vacuum pipe is prefabricated in the factory and vacuumize, job site can not also cannot be carried out being welded to connect and use complicated work, facility to carry out installation exercise.Therefore, the connector of vacuum heat-insulated pipe and coupling method need to carry out special consideration, guarantee sealing property good, reliable, the heat-insulating property of integral type, quick, easy field-mounted process and maintainability in design.
