Abstract
The utility model belongs to the pipeline fittings of a heat distribution pipeline. The bottom of the bracket is fixedly connected with a mirror surface stainless steel upper slide plate to form a pipe supporting part. A plurality of circular or other-shaped composite interlayer sliding plate pieces filled in polytetrafluoroethylene are respectively put into the corresponding holes of position limiting fixed plates and form new sliding friction pair with the couple of the mirror surface stainless steel upper slide plate of the upper part. The utility model has simple and reasonable structural design and high safety, uses the multidigit embedded fixed structure and the interlayer composite sliding plate pieces filled in polytetrafluoroethylene to make the utility model have good use effect and is capable of reducing the technical cost of the heat distribution pipeline, etc.
Description
The utility model belongs to the pipeline fittings of heat distribution pipeline, is used to reduce the friction thrust of pipeline.A kind of filled polytetrafluoroethylene sliding support of main proposition is applicable to all heat distribution pipelines that need compensation design, is applicable to that also thermal walking need reduce the bridge of surface friction drag, equipment etc.
Packaged type bearing between employed ground buttress and conduit saddle in above-mentioned technical field at present, mainly contain two types: a kind of is all kinds of roll type bearings, its friction factor is by 0.1 design, but owing to factor affecting such as manufacturing and environmental corrosions, actual friction factor far surpasses design load.Second kind is the sliding support that forms between carbon steel board, and its coefficient of sliding friction is 0.3.For satisfying the designing requirement that reduces friction factor, the employing that has directly is encased inside the technology of two polyfluortetraethylene plates between the carbon steel board of carbon steel sliding support, utilize the characteristics of the low coefficient of sliding friction of this solid lubricant of teflon to make sliding support, the bearing of this directly pad people polyfluortetraethylene plate, owing to there is not the structure Fixed Design, two polyfluortetraethylene plates are because of the adhesion between its creep and material of the same race, slip away the friction interface together and lose efficacy; Three above countersunk head screws of the employing that also has are fixed on the big plate of teflon on the upper and lower base plate of sliding support, because the linear expansion coeffcient of the polyfluortetraethylene plate that is fixed is much larger than the linear expansion coeffcient of steel substrate, the shearing stress that two kinds of sheet material fixedly occurs on the interface when temperature variation makes it inefficacy.What also have except that above-mentioned situation is bonded in filling-modified polytetrafluoroethylene (PTFE) sliding plate sheet on after treatment the matrix steel plate with tackiness agent, this method has still that peeling strength is very low, tackiness agent natural aging, bonding life-span are short, can not with problems such as susceptor design is complementary working life.
In view of existing problem in the prior art, task of the present utility model is: design and a kind ofly can make full use of the polytetrafluoroethylmaterial material characteristic, and rational in infrastructure, sliding support safely and effectively in job applications.
The utility model is finished the technological scheme that its invention task takes: at the fixedly connected mirror finished stainless steel upper slide of the frame bottom that is used for jacking pipeline or bearing load, several filled polytetrafluoroethylene composite intermediate layer slip plates circular or other shape embed respectively in the respective aperture of spacing fixed plate, and the linear expansion amount that makes each filled polytetrafluoroethylene composite intermediate layer slip plate is all in the location tolerance scope that embeds, filled polytetrafluoroethylene composite intermediate layer slip plate combines with the mirror finished stainless steel upper slide couple on top and forms friction pair, form the novel sliding friction pair of mirror finished stainless steel upper slide and filled polytetrafluoroethylene composite intermediate layer slip plate thus, its dry sliding friction coefficient empirical tests is 0.06 to 0.10, and spacing fixed plate bottom is provided with infrabasal plate and also is fixedly connected with it as its base plate.
Then can be filled polytetrafluoroethylene composite intermediate layer slip plate is fastening in the center when being inverted use by one piece of countersunk head screw.
The support of jacking pipeline or support loading can be made up of side plate, riser and upper substrate, and the mirror finished stainless steel upper slide is fixedlyed connected formation conduit saddle portion with the upper substrate of support.
When the utility model is used for pipeline construction, the conduit saddle portion that will be made of the mirror finished stainless steel upper slide of side plate, riser, upper substrate and bottom is welded on the pipeline, and the basic courses department that filled polytetrafluoroethylene composite intermediate layer slip plate, spacing fixed plate and infrabasal plate are constituted is welded on giving on the reason steel plate of folder pier by infrabasal plate.
Spacing fixed plate is the orifice plate of stamping-out processing, filled polytetrafluoroethylene composite intermediate layer slip plate is the plate by the powder cold press and sintering, wherein the filled polytetrafluoroethylene sandwich layer will play the reduction linear expansion coeffcient, creep rate and the effect that improves permissible compression stress, the top layer of pure teflon has guaranteed the dry sliding friction coefficient that it is low.
The utility model compared with prior art, reasonable in design, simple in structure, safety reliability improves, adopt the multidigit damascene structures to fix, solved because the fixing difficult problem of the structure that the big and high creep of teflon linear expansion coeffcient brings, employing filled polytetrafluoroethylene composite intermediate layer slip plate has improved 2-3 times of permissible compression stress, and makes the utility model friction pair have low dry sliding friction coefficient 0.06-0.10.Be applied to heating pipeline, can reduce friction thrust more than 2/3rds, thereby can reduce the cost of engineerings such as heating pipeline significantly, particularly more remarkable to its effect of high aerial pipeline.
Embodiment's accompanying drawing is;
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 3 is a teflon composite intermediate layer plate schematic representation.
The embodiment who provides is in conjunction with the accompanying drawings further specified the utility model structure:
As shown in drawings: the utility model top conduit saddle portion is by side plate 1, riser 2, upper substrate 3 and the mirror finished stainless steel upper slide 4 that is fixedly connected in the substrate bottom constitute, spacing fixed plate 6 is for having the orifice plate of a plurality of circular ports, with infrabasal plate 7 welding one, several circular filled polytetrafluoroethylene composite intermediate layer slip plates 5 embed respectively in the hole of spacing fixed plate 6, all in the location tolerance that embeds, teflon composite intermediate layer slip plate and mirror finished stainless steel upper slide couple form novel sliding friction pair to the linear expansion amount that makes each filled polytetrafluoroethylene composite intermediate layer slip plate.
Filled polytetrafluoroethylene composite intermediate layer slip plate 5 is that the top layer by filled polytetrafluoroethylene sandwich layer and pure teflon is composited.
