Abstract
The utility model provides an anti-corrosion and heat-insulation sealing device for prefabricated insulated pipeline compensator and a protective device for the compensator, which consists of a sealing coating tube, a sealing supporting moving ring, an organic heat insulation layer and an inorganic heat insulation layer that are positioned outside a compensator, a welding tube of compensator, a pipeline reserved welding tube and a pipeline coating tube. The utility model has characteristics of simple structure, low cost and long service life as well as perfect making and mounting technology, and well anti-corrosion and heat-insulation effect, thereby being applicable to underground high temperature pipelines in particular.
Description
Technical field
The utility model relates to anticorrosion, insulation, the seal arrangement of insulation pipe compensator, is applicable to that mainly the insulation pipe outer sleeve expands, the contraction deformation compensation.
Background technique
At present, burying ground soak pipeline is that prefabricated insulation pipe compensator is arranged on the joint, and its subject matter is that seal for pipe joints is bad, and heat insulation effect is poor, fully waterproof.For addressing the above problem, existing pipeline compensator is arranged on technological achievement within insulation, the seal arrangement, play certain effect.But this apparatus structure is complicated, and only organic heat-insulating layer, inorganic insulating layer, soft inorganic insulating layer and filler etc. just reach several layers, and manufacturability is poor, and it is many to relate to material, and cost is higher relatively, and can't realize whole synchroballistic on its structure.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at prior art, design provides a kind of prefabricated thermal insulation pipeline compensator corrosion-resistant thermal insulation seal arrangement, reaches to simplify product structure, reduce production costs, improve usability, realize the purpose of whole synchroballistic.
Basic design of the present utility model is, is provided with sealing and supports shift(ing) ring between hermetically sealed case tube and tube road outer sleeve, and this shift(ing) ring is fixedlyed connected with the pipeline outer sleeve, can move to axial and seal with the hermetically sealed case pipe; Support hermetically sealed case tube and tube road outer sleeve, the pipeline of shift(ing) ring inboard in sealing and reserve configuration organic heat-insulating layer and inorganic insulating layer in the annular space that constitutes between welded pipe, compensator welded pipe and the compensator, or inorganic insulating layer all is set; This device integral shaft is to left and right symmetry.On the outside axial direction of hermetically sealed case pipe, be provided with the hot melt butt joint.
The utlity model has simple in structure, manufacturing and mounting process is good, corrosion-resistant thermal insulation good sealing effect, cost are low, the characteristics of long service life.
Description of drawings
Fig. 1 is a prefabricated thermal insulation pipeline compensator corrosion-resistant thermal insulation seal arrangement general structure schematic representation;
Fig. 2 is a hermetically sealed case tube-surface hot melt butt joint positional structure schematic representation.
Piece number explanation among the figure:
1, shift(ing) ring, 4, organic heat-insulating layer, 5, inorganic insulating layer, 6, pipeline reservation welded pipe, 7, compensator welded pipe, 8, compensator, 9, hot melt butt joint are supported in pipeline outer sleeve, 2, hermetically sealed case pipe, 3, sealing.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Prefabricated thermal insulation pipeline compensator corrosion-resistant thermal insulation seal arrangement comprises pipeline outer sleeve 1, pipeline reservation welded pipe 6, compensator welded pipe 7 and compensator 8, between hermetically sealed case pipe 2 and pipeline outer sleeve 1, be provided with sealing and support shift(ing) ring 3, sealing supports shift(ing) ring 3 fixedlys connected with pipeline outer sleeve 1, can move to axial and seal with hermetically sealed case pipe 2; The hermetically sealed case pipe 2 of example and pipeline outer sleeve 1, pipeline are reserved configuration organic heat-insulating layer 4 and inorganic insulating layer 5 in the annular space that constitutes between welded pipe 6, compensator welded pipe 7, the compensator 8 in shift(ing) ring 3 is supported in sealing, or inorganic insulating layer 5 all is set; This device integral shaft is to the left and right sides symmetry.Outside axial direction along hermetically sealed case pipe 2 is provided with hot melt butt joint 9.
During use, to reserve welded pipe 6, compensator welded pipe 7, compensator 8 different with hermetically sealed case pipe 2 materials because of pipeline outer sleeve 1, pipeline, heat expansion is different with the shrinkage coefficient, it is axially displaced with pipeline outer sleeve 1 relative hermetically sealed case pipe 2 to make sealing support shift(ing) ring 3, breaking plant not, guarantee the operation quality and the effect of anticorrosion, insulation, sealing configuration, and realize whole synchroballistic.
