Description

Thermal insulation pipe for telescopic pipeline

Technical Field

The utility model relates to a thermal insulation pipe, especially a thermal insulation pipe for scalable pipeline belongs to chemical industry equipment technical field.

Background

In chemical production, because of the mechanical vibration directly connected with the pipeline and the vibration caused by the unstable flow of the fluid in the pipeline, the vibration has great destructive effect on the pipeline, and the serious vibration can cause the pipeline to break and crack, thus threatening the safe operation of the system. In order to prevent destructive influence of vibration on pipelines and equipment, at present, stainless steel metal hoses, corrugated expansion joints, corrugated pipe compensators and the like are often adopted at joints of equipment such as pumps, fans and the like and pipelines on medium conveying pipelines such as steam, water, oil, various industrial gases, medicines and the like to reduce and prevent influence of vibration on the pipelines, for longer pipelines, due to influence of expansion with heat and contraction with cold, the metal hoses or the corrugated pipes also need to be installed to compensate for the expansion with heat and contraction with cold, and the metal flexible connections are adopted to compensate for movement of a pipeline system, so that the expansion with heat and the vibration absorption play important roles. In actual production, the steam of carrying in the pipeline, mediums such as cooling water and raw materials often need to carry out the heat preservation operation, to ordinary pipeline, there are a lot of heat preservation means among the prior art, if adopt insulation material parcel pipeline, adopt modes such as compound insulating tube to keep warm to transport medium, but to compensating pipe such as stainless steel metal collapsible tube, ripple telescopic joint, bellows compensator, because compensating pipe is in dynamic flexible state at work, can't wrap fixed heat preservation in the outside package of pipeline, lead to the invalid heat loss in metal collapsible tube position, especially in the pharmaceutical industry, same reation kettle has a large amount of access pipelines, the accumulated heat loss of compensating pipe on each access pipeline has resulted in a large amount of energy extravagant.

Disclosure of Invention

The utility model aims to provide a: the heat preservation pipe for the telescopic pipeline can change the length along with the expansion of the pipeline, can effectively preserve heat of the compensating pipelines such as a stainless steel metal hose, a corrugated expansion joint, a corrugated pipe compensator and the like, and prevents unnecessary heat or cold loss.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the heat preservation pipe for the telescopic pipeline is formed by sequentially connecting a plurality of built-in pipes and an outer sleeve, wherein the built-in pipe main body is a hollow cylindrical inner pipe body, clamping rings protruding outwards are arranged at two ends of the inner pipe body, the outer sleeve main body is a hollow cylindrical sleeve body, two ends of the sleeve body are provided with lantern rings extending towards the direction of a central axis in the sleeve body, the inner wall of each lantern ring is in sliding fit with the outer side wall of the inner pipe body of the adjacent built-in pipe, and the outer side wall of each clamping ring is in sliding fit with the inner side wall of the sleeve body of the adjacent outer sleeve; the built-in pipe comprises an inner pipe heat-insulating layer and an inner pipe coating layer, the inner pipe coating layer is sleeved outside the inner pipe heat-insulating layer, and the clamping ring is fixedly connected with the inner pipe coating layer; the outer sleeve comprises a sleeve heat-insulating layer and a sleeve fastening layer, the sleeve heat-insulating layer is sleeved outside the sleeve fastening layer, and the lantern ring is fixedly connected with the sleeve fastening layer; furthermore, the heat preservation pipe for the telescopic pipeline also comprises a gasket sleeved on the outer side of the inner pipe body, and the gasket is arranged between the clamping ring and the lantern ring in a cushioning mode; further, the inner tube coating layer of the inner tube and the sleeve fastening layer of the outer sleeve are polyethylene or polytetrafluoroethylene layers.

The utility model discloses an actively beneficial technological effect lies in: through setting up inner tube and outer tube that can relative slip, can make the utility model provides an insulating tube is flexible in certain length, the cover is established when establishing on scalable pipelines such as metal collapsible tube, can change self length along with inside required heat retaining pipeline length change, guarantee the heat preservation effect, the packing ring of setting between the snap ring and the lantern ring, can be when there being the clearance between the snap ring and the lantern ring, guarantee the heat preservation effect, the inner tube coating of inner tube and the sleeve pipe fastening layer of outer tube set up to polyethylene or polytetrafluoroethylene layer, can utilize self-lubricating material's lubricated effect to make and slide more smoothly between inner tube and the external pipe, gain better application effect.
