Abstract
The invention provides a novel compressive compensation device which comprises a working steel tube, a thermal insulating layer and an outer protective steel tube, wherein the thermal insulating layer wraps the working steel tube, the outer protective steel tube is sleeved on the thermal insulating layer, and a strengthening rib is connected between the working steel tube and the outer protective steel tube. The novel compressive compensation device has the advantages of convenience in machining and transportation, stable connection, corrosion resistance and the like.
Description
Technical field
The invention belongs to steam line device technique field, especially relate to a kind of prefabricated direct-buried steam insulation pipe fitting connecting bend.
Background technique
Thermal insulation pipe in existing technology (comprising compensation device, threeway, four-way) is that a kind of good heat insulating, direct-burried safe and reliable, that engineering cost is low are heat preservation pipe prefabricated.It has solved the waterproof of the insulation of the insulation of thermal insulation pipe in the various pipework such as heat supply, cooling, heating power, electric power, chemical industry, curved part, slide lubricated, exposed pipe end, eight crook, problem such as anticorrosion effectively.Not only have advanced technology, practicability that traditional trench and built on stilts channelling hardly match, but also have remarkable social benefit and economic benefit, energy conservation and environmental protection benefit.But the problem that insulation compensation device commonly used damages when having carrying and construction.
Summary of the invention
For solving the problems of the technologies described above, the present invention provides a kind of prefabricated direct-buried steam insulation pipe fitting novel resistance to compression compensation device, and its concrete technological scheme is following:
A kind of novel resistance to compression compensation device, by working steel tube, thermal insulation layer and external protective steel tube are formed, and said thermal insulation layer is wrapped in outside the said working steel tube, and said external protective steel tube is enclosed within outside the said thermal insulation layer, is connected with rinforcement bar between said working steel tube and the said external protective steel tube.Said external protective steel tube outer side surface has corrosion-inhibiting coating.Said external protective steel tube is welded for the multistage straight steel pipe.Thermal insulation layer adopts soft thermal insulating material at deformation section, like glass wool etc.Compensation device external protective steel tube diameter is not less than the straight tube that links to each other with compensation device and protects the steel bushing diameter outward.
Advantage and good effect that the present invention has are: owing to adopt technique scheme; This steam line compensation device inner and outer pipe is reinforced and locatees; The processing of external protective steel tube need not bend pipe, and easy-rupturing not after the welding has that processing is easy, convenient transportation, connection is firm and advantage such as anticorrosion.

Embodiment
As shown in Figure 1; The steam insulation pipe fitting compensation device that the present invention introduces, by working steel tube, thermal insulation layer and external protective steel tube are formed; Thermal insulation layer is wrapped in outside the working steel tube; External protective steel tube is enclosed within outside the thermal insulation layer, is connected with rinforcement bar between working steel tube and the external protective steel tube, prevents the relative displacement of working steel tube and external protective steel tube and deviating from of thermal insulation layer.The external protective steel tube outer side surface has corrosion-inhibiting coating, can play the effect of opposing drying, humidity or electrolytic corrosion.External protective steel tube need not to process in addition the external protective steel tube bend pipe for the multistage straight steel pipe is welded, and saves material and operation.Thermal insulation layer adopts soft thermal insulating material at deformation section, like glass wool etc.The compensation device wall thickness of in construction, choosing is not less than the straight length wall thickness, and should carry out Stress calculation.When utilizing compensation device as thermal compensation, compensation device external protective steel tube diameter should be not less than the straight tube that links to each other with compensation device and protect the steel bushing diameter outward.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
