Description

A kind of heating pipeline compensator

Technical field

The utility model relates to heat distribution pipeline, is specifically related to a kind of heating pipeline compensator.

Background technique

Heat distribution pipeline be for from boiler room, the thermal source such as direct combustion machine room, heat supply center leads to the heat supply pipeline of building consumer heat inlet, according to the difference of fed sheet of a media, heat distribution pipeline can be divided into hot water pipeline, steam line and condensing water conduit.

Wherein, for the heat distribution pipeline of delivering vapor, its operating temperature difference is larger, and existing heat distribution pipeline obtains primarily of there being the carbon steel of expansion and contraction property, when specifically using, if pipeline long enough, the heat expansion caused because of the temperature difference makes the elongation of pipeline very large, so need to install compensator on pipeline.

Existing pipeline compensator is generally the compensator of bend pipe compensator, corrugated expansion joint or its great waves pipe insulation; Wherein bend pipe and corrugated expansion joint, design time need consider install time tightly cold, to the guide type shoe preventing compensator unstability be installed on pipeline during installation; And the compensator structure of outer sleeve insulation is complex-shaped, is especially enclosed within pipe outside pipe fitting and forgets axial direction and there is knuckle, when pipe network occurs to leak, easily accidents caused.

In order to solve existing heating pipeline compensator above shortcomings, the utility model have developed a kind of heating pipeline compensator of new structure.

Summary of the invention

The purpose of this utility model is to provide a kind of heating pipeline compensator.

The utility model is achieved through the following technical solutions:

A kind of heating pipeline compensator, comprise compensator body and respectively with the connecting tube of compensator two ends by Flange joint; Wherein said connecting tube forms by three layers, and internal layer is polypropylene tube, and skin is polyvinyl chloride pipe, and mesosphere is high-temperature resistant fiber class thermal insulation layer; Described compensator body is ripple type compensator, ring set is fixed with in the ripple type sleeve pipe of Steel Sleeve at skin, forming annular sealed space respectively between ripple type sleeve pipe and compensator body, Steel Sleeve, is high-temperature resistant fiber class thermal insulation layer in described annular sealed space.

The utility model and compensator two ends are three layers by the connecting tube of Flange joint, compare the connecting tube using now aluminium parcel, high-temperature resistant fiber class thermal insulation layer wherein better can play the effect of insulation, and can reduce the deformation quantity that pipeline expands with heat and contract with cold, longer service life; And ripple type compensator is sleeved on and is all in the sleeve pipe of ripple type, thermal insulating material is set in confined space, and is provided with thermal insulation layer and steel pipe again at the skin of sleeve pipe, can effectively prevent webmaster to be destroyed.

Compared with prior art, the utility model high insulating effect, can effectively avoid temperature stress to concentrate and the heat distribution pipe network accident that causes, and structure is simple, is easy to construction.

Fig. 1 is structural representation of the present utility model;

In figure: 1-compensator body, 2-connecting tube, 3-ripple type sleeve pipe, 4-Steel Sleeve, 5-internal layer, 6-mesosphere, 7-skin, 8-thermal insulation layer, 9-flange.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A kind of heating pipeline compensator as shown in Figure 1, comprises compensator body 1 and the connecting tube 2 be connected by flange 9 with compensator two ends respectively; Wherein said connecting tube 2 forms by three layers, and internal layer 5 is polypropylene tube, and outer 7 is polyvinyl chloride pipe, and mesosphere 6 is high-temperature resistant fiber class thermal insulation layer; Described compensator body 1 is ripple type compensator, ring set is fixed with in the ripple type sleeve pipe 3 of Steel Sleeve 4 at skin, forming annular sealed space respectively between ripple type sleeve pipe 3 and compensator 1 body, Steel Sleeve 4, is high-temperature resistant fiber class thermal insulation layer 8 in described annular sealed space.
