Abstract
The utility model discloses a steel outer protection polyurethane heat preservation elbow, which comprises an elbow pipe body. A high-density polyethylene outer projection pipe is coated outside the elbow pipe body. A zinc-plating iron sheet outer protection layer is coated on the periphery of the high-density polyethylene outer protection pipe. A polyurethane heat preservation layer is filled between the elbow pipe body and the high-density polyethylene outer protection pipe. Sponge stripes are filled between the high-density polyethylene outer protection pipe and the zinc-plating iron sheet outer protection layer. A zinc-plating iron sheet is prefabricated in the polyurethane foam heat preservation elbow. The heat preservation performance of the elbow is improved by the polyurethane heat preservation layer. Due to the sponge strips filled in the zinc-plating iron sheet outer protection layer, an enough space is provided for expansion of the elbow, so that the zinc-plating iron sheet outer protection layer can be ensured not to be deformed or damaged.
Description
Technical field
The utility model relates to a kind of elbow structure, relates in particular to a kind of steel and protects the polyurethane heat-insulation elbow outward.
Background technique
Elbow is the conduit component of using always.
In the construction of prefabricated thermal insulation pipeline, because the built on stilts prefabricated thermal insulation pipeline that lays is directly exposed under the sunlight, do not have the constraint of soil to pipeline, pipeline is in operation and can produces bigger thermal expansion displacement, and the use of the elbow thermal expansion displacement of extraction duct to a certain extent.
But existing elbow has used such as thermal insulating materials such as rock wools, and not only thermal insulation property is barely satisfactory, and this thermal insulating material life-span is very short.In addition, during the working environment of elbow was in and exposes to the sun and rain, though the improvement that adds external protection outside elbow is arranged, still, when being subjected to displacement when the thermal expansion of elbow extraction duct, external protection of the prior art just was easy to distortion and damages.
The model utility content
The utility model provides a kind of steel to protect the polyurethane heat-insulation elbow outward at the drawback of prior art.
Steel described in the utility model protects the polyurethane heat-insulation elbow outward, comprises the elbow body, the outer pillar of the external coating high density polyethylene (HDPE) of described swan neck, the peripheral galvanized sheet iron outer protective layer that coats of the outer pillar of this high density polyethylene (HDPE); Outside elbow body and high density polyethylene (HDPE), be filled with polyurethane insulation coating between the pillar, outside high density polyethylene (HDPE), be filled with sponge strip between pillar and the galvanized sheet iron outer protective layer.
Steel described in the utility model protects outward in the polyurethane heat-insulation elbow, by the thermal insulation property that polyurethane insulation coating improves elbow is set, the sponge strip of filling in the galvanized sheet iron outer protective layer then provides the allowance space for elbow expands, and can guarantee that the galvanized sheet iron outer protective layer does not deform and damages.
Description of drawings
The cross-sectional schematic that Fig. 1 protects the polyurethane heat-insulation elbow outward for steel described in the utility model;
Another cross-sectional schematic that Fig. 2 protects the polyurethane heat-insulation elbow outward for steel described in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1 and Figure 2, steel described in the utility model protects the polyurethane heat-insulation elbow outward, comprises elbow body 1, coats the outer pillar 4 of high density polyethylene (HDPE) outside the described elbow body 1, the outer pillar 4 peripheral galvanized sheet iron outer protective layers 2 that coat of this high density polyethylene (HDPE); Outside elbow body 1 and high density polyethylene (HDPE), be filled with polyurethane insulation coating 5 between the pillar 4, outside high density polyethylene (HDPE), be filled with sponge strip 3 between pillar 4 and the galvanized sheet iron outer protective layer 2.
In the utility model, when elbow absorbed the thermal expansion displacement of prefabricated thermal insulation pipeline, the cavity between soft sponge strip, prefabricated direct-buried insulation elbow outer surface and the galvanized sheet iron external protection can be protected the galvanized sheet iron outer protective layer not deform and damage; The galvanized sheet iron outer protective layer plays further protection and water-tight effect, can sun-resistantly drench with rain, and guarantees outward appearance and other built on stilts conformity with prefabricated thermal insulation pipeline parts of elbow.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
Claims (1)
1. a steel protects the polyurethane heat-insulation elbow outward, comprises the elbow body, it is characterized in that the outer pillar of the external coating high density polyethylene (HDPE) of described swan neck, the peripheral galvanized sheet iron outer protective layer that coats of the outer pillar of this high density polyethylene (HDPE); Outside elbow body and high density polyethylene (HDPE), be filled with polyurethane insulation coating between the pillar, outside high density polyethylene (HDPE), be filled with sponge strip between pillar and the galvanized sheet iron outer protective layer.
