Description
Technical field
The utility model belongs to the pipe transportation technology field, relates in particular to the conduit saddle that the directional support of cold conditions medium transport pipeline is used.
Background technique
Along with the develop rapidly of China's Petrochemical, large-scale normal, middle high-pressure low tempertaure storage technology (such as liquid ethylene, liquid gas, rock gas etc.) obtains wide popularization and application, the long distance of various low temperature liquid material media is carried proposed Secretary.The length of pipeline medium directly affects the Economy of basin district operation apart from transfer efficiency, therefore the medium transport loss of refrigeration capacity of pipeline is subject to great attention in the industry, cold insulation pipe carrier has solved because plain carbon steel structural tube support causes the discontinuous cold bridge that forms of thermal insulating material and has cut off, reduced the loss of refrigeration capacity of pipeline, the temperature drop of the pipeline medium that long distance is carried is guaranteed.
The difference of linear expansion of different cold insulation materials is very large, and the shrinkage amount difference of material is also very large.This so that cold insulation pipe carrier under the low-temperature operation operating mode, because of pipeline different with the linear expansion coeffcient of conduit saddle cold insulation piece, the contour projector of pipeline and conduit saddle cold insulation piece is also different and cause producing between pipeline and the conduit saddle cold insulation piece gap, and operating pipeline can expand with heat and contract with cold the generation displacement and vibrate.The shrinkage displacement that the while pipeline should expand with heat and contract with cold and produce makes between pipeline and the conduit saddle segregation phenomenon to have occurred, and cold insulation pipe carrier can not slide with pipeline, causes the cold insulation material on cold insulation pipe carrier axial two end faces cold insulation piece and the pipeline to occur disconnecting.Cold in disconnection place can directly pass in the atmosphere, because " cold " air contacts with " heat " air, can produce the dewfall phenomenon in disconnection place of conduit saddle end face and pipeline cold insulation material, even freeze, because the density of the density ratio water of ice is little, can allow the gap support greatly more steam enter the pipeline cold insulation structure, pass in time, the volume of ice is also increasing, finally causes the cold insulation layer structural damage of conduit saddle.Bring potential safety hazard for whole pipe-line system, and cause great loss of refrigeration capacity.
At present, some cryogenic pipelines such as a large amount of construction project such as LNG, LPG, oil transport pipeline, low-temperature storage tank need pipeline support when the pipeline fed sheet of a media, and the normal displacement of cold insulation pipeline avoids causing that the amplitude of pipeline is very large.Traditional conduit saddle does not just satisfy such occasion, needs a kind of spacing conduit saddle of original slip that is different from of exploitation, both can be spacing also slidably, assurance pipeline performance safety.
Be widely used in petrochemical industry, control gold, refrigeration, empty minute engineering, low-temperature material storage and the conveying engineering of the industries such as food, communications and transportation, building.
The model utility content
For the defective that exists in the prior art and technical problem, the utility model provides a kind of cold insulation spacing conduit saddle that slides, thereby can prevent conveyance conduit owing to the excessive vibration that causes of pipeline localized stress that the reason such as expand with heat and contract with cold causes, guarantee the safe operation that pipeline is carried.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of cold insulation spacing conduit saddle that slides, comprise cold insulation piece, upper curved plate, lower curved plate, dunnage and floor, described cold insulation piece is wrapped on the outer wall of delivery pipe, described upper curved plate and lower curved plate are set in respectively the upper and lower of cold insulation piece, and are fixedly connected with by fastening piece; Described dunnage is fixed on the bottom of lower curved plate, and described floor level is located at the lower end of dunnage, and the bottom on floor is provided with two bounding meanss.
As preferably, described cold insulation piece comprises cold insulation piece and lower cold insulation piece, and the junction plane of upper cold insulation piece and lower cold insulation piece is provided with every cold sealing gasket.
As preferably, described floor has thrust piece, and this thrust piece is between two bounding meanss.
As preferably, described lower curved plate both sides are respectively equipped with thrust block and fixed block.
Beneficial effect: with respect to prior art, the utlity model has following advantage: by axial limiting, radially slide excessive or the excessive and vibrative problem of displacement of pipeline localized stress that solves; Simple in structure, easily manufactured, both solved the cold insulation problem, eliminated again the localized stress problems of too, can prolong the working life of pipeline, guarantee safe operation.

Wherein, delivery pipe 1, upper cold insulation piece 2, lower cold insulation piece 3, upper curved plate 4, lower curved plate 5, dunnage 6, floor 7, every cold sealing gasket 8, stiffening rib 9, bounding means 10, thrust piece 11, thrust block 12, fixed block 13.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
A kind of cold insulation spacing conduit saddle that slides is the composited pipe suspension and support that forms by every cold material, rigidity clip (arc plate), limit assembly and fastening piece.It comprises cold insulation piece 2, lower cold insulation piece 3, upper curved plate 4, lower curved plate 5, dunnage 6 and floor 7, wherein go up cold insulation piece 2 and lower cold insulation piece 3 employing polyurethane every cold material, should be every cold material by specialized mould via a kind of sealing porous structure that chemical raw material foaming forms, have fire-retardant (oxygen index 〉=30%), do not absorb water, heat-transfer coefficient low (0.02～0.035w/m.k), the compound one's best quality of intensity high (20 MPa).Described upper cold insulation piece 2 and lower cold insulation piece 3 are wrapped in respectively on the outer wall of delivery pipe 1, and arrange every cold sealing gasket 8 on the junction plane between them, then upper curved plate 4 and lower curved plate 5 are enclosed within on the cold insulation piece, and by fastening piece (bolt assembly) with cold insulation piece fixing and locking on pipeline outer wall, be fixed with dunnage 6 in the bottom of lower curved plate 5 in addition, in order to improve the intensity of dunnage 6, at dunnage 6 welding stiffening ribs 9, the bottom that is fixed in dunnage 6 of while described floor 7 levels, and 7 bottoms, floor also are provided with two bounding meanss 10, floor 7 is placed on the thrust piece 11, and thrust piece 11 is between the bounding means 10, move axially spacing purpose thereby reach.In addition, thrust block 12 and fixed block 13 are set in the both sides of lower curved plate 5.
In the utility model extensive use chemical industry, oil refining, petrochemical industry, LNG, ethene and the storage tank project, both can be spacing also slidably, can cold insulation again can vibrationproof cold insulation pipe carrier.By fastening piece and dish-shaped gasket construction, utilization makes the arc plate that the cold insulation piece is clamped on the pipeline, has solved the amount of the expanding with heat and contract with cold differences that produce owing to material is different and has caused between cold insulation material and pipe clamp, the pipeline and produce the difficult problem that the gap causes conduit saddle clamping bolt pretightening force to be become flexible.By axial limiting, radially slide excessive or the excessive and vibrative problem of displacement of pipeline localized stress that solves.
