Description
Technical field
The utility model belongs to a kind of pipe support, relates to the flexible bearing support of a kind of large-diameter pipeline be under high temperature or worst cold case specifically.
Background technique
Pipeline is the important mode of a kind of fluid conveying, and especially in the production process of chemical industry, metallurgy, heating power etc., the fluid be transferred may relate to the operating modes such as high temperature, low temperature, high pressure, shock and vibration, corrosion and wearing and tearing.This will propose special requirement to the design of pipeline and supporting thereof.Such as, high-temperature gas transmission pipeline generally will arrange insulated lining and thermal insulation layer in metal pipe internal wall and outer wall; Low temperature gas transmission or liquid-transport pipe-line generally can arrange thermal-protective coating or insulation casing at metallic conduit outer wall; The heat distribution pipeline of delivering vapor or hot water generally also will carry out heat-insulation and heat-preservation process.Moreover, industrial pipeline also always can be embedded in underground or lay along ground, more by built on stilts, along laying from all directions, to meet the needs of production, then the load of pipeline, is comprised the weight of conveying fluid, self weight of pipeline, thermal-protective material weight and various additional load and all will be transmitted by pipe-supporting bearing, wherein, by the conveying temperature of fluid and the load that causes of the temperature difference of ambient temperature be susceptor design most important be also a load of the most difficult expectation.The conversion in season, the fluctuation of operation all can cause the variation of pipeline and Bearing Seat Force.Thus, will become extremely important to rationally pipe-supporting seat structure design reliably high temperature and cryogenic piping.
With the industrial expansion such as chemical industry, metallurgy, the structure style for the support, bracket, suspension bracket, guiding base, spacing base, slip joint, expansion joint, bellows etc. of different occasion pipeline is a lot, forms the quite a few of serial and standard.HG/T21629 " pipe support standard drawing " and GB/T12777 " metal corrugated pipe expansion joint general technical specifications " etc. are the most frequently used standards of current chemical pipe design, but to some slightly particular point occasion be not easy to choose desirable pipe-supporting pattern, especially to the high-temperature pipe of some major diameter heavy loads.Such as, the temperature difference flexible compensation of pipeline neither total energy realize by elbow, and along with the maximization of device, the high-temperature and pressure pipeline of two or three rice diameter has not been what is fresh, such pipeline relies on owing to not having ready-made standard, sometimes has to take the support design that the mode of piecing together has been come it.
Summary of the invention
The purpose of this utility model is to provide a kind of high/low temperature pipeline extension bearing being applicable to major diameter, heavy load, large temperature difference place.
High/low temperature pipeline extension bearing of the present utility model, it comprises metallic conduit, expansion joint, expansion joint guide protective tube, insulated lining, spacing conduit saddle, it is characterized in that being positioned on the metallic conduit of spacing conduit saddle both sides and respectively have an expansion joint, (metal pipe internal wall has expansion joint guide protective tube to corresponding expansion joint, metal pipe internal wall has insulated lining, insulated lining between two expansion joints axially middle part has expansion joint, Elastic heat insulation material is filled at expansion joint, the conduit saddle that leads respectively is arranged at the bottom being positioned at the metallic conduit outside two expansion joints, spacing conduit saddle is fixedly connected with common backplane.Respectively have one piece of guide pipe butt plate (14) under each guiding conduit saddle respectively, guiding conduit saddle is by being flexibly connected to conduit saddle base plate with common backplane.
It is be connected with common backplane by the slotted hole of 4 on guide pipe butt plate with 4 bolts that guiding conduit saddle as above and common backplane are flexibly connected, between bolt with on the common backplane of metallic conduit Vertical direction, have club.
Guiding conduit saddle as above with spacing conduit saddle center line for reference symmetry distributes.
Common backplane as above is positioned at inside bolt and has club baffle plate, for carrying out spacing to club.
Expansion joint as above can be single ripple, also can be many ripples (or claiming bellows).
Expansion joint as above is according to occasion needs, and remove expansion joint and the guiding conduit saddle of spacing conduit saddle side, retain opposite side, then seat structure is just turned into one-way expansion form.
The feature of the utility model bearing is that the design of expansion joint and guiding conduit saddle carry relative to supporting flue and defining dual freedom on stretching, and expansion joint is placed between spacing conduit saddle and guiding conduit saddle, make expansion joint work from the impact of radial force, radial force, also namely pipeline weight is then all born by guiding conduit saddle.The bolt hole of guide pipe butt plate adopts vertically in slotted hole, and up and down with double nut location, base plate bottom is designed with many clubs, makes it have carrying and guiding two-fold advantage freely concurrently.The triangular collaborative effect that formation is flexible, spacing again that cooperatively interacts of spacing conduit saddle, expansion joint, guiding conduit saddle, makes axial force digest on the spot and is unlikely to marry again next fulcrum.Meanwhile, the structural type of this bearing also has good flexibility in design for the type of fluid of Cemented filling, pressure, temperature.
Bearing is externally connected by common backplane, connecting bolt and nut and fixes.Common backplane can be seated in concrete foundation, also can be fixed on steel structure or steel platform.
This form pipe support can form a kind of series product or a standard according to different pipeline specifications and pressure rating.
Advantage of the present utility model: this pipe support has and integrates carrying, guiding, spacing, flexible function, broad application temperature range, and can form series and standardized product, has technology and business concurrently and promotes and be worth.
