Abstract
The invention discloses a heat insulating structure of a directly-buried middle-temperature and low-temperature hot water sleeve compensator. A movable end outer protecting pipe is sheathed outside the movable end pipe of the compensator. One end of the movable end outer protecting pipe is connected with a connecting casing and the other end of the movable end outer protecting pipe is connected onto a slideable support frame. A heat insulating layer is sheathed on the fixed end pipe of the compensator. A fixed end outer protecting pipe is sheathed outside the heat insulating layer. A rubber corrugated pipe is arranged between the movable end outer protecting pipe and the fixed end outer protecting pipe. An outer casing is welded at the upper ends of the movable end outer protecting pipe and the fixed end outer protecting pipe through an annular plate. The heat insulating structure of the directly-buried middle-temperature and low-temperature hot water sleeve compensator has the advantages that the heat insulating structure does not need a connecting pipe, the outer protecting pipes are not required to adopt a reducing structure, the processing technology is simple and the cost is low; and since the rubber corrugated pipe is used in the heat insulating structure, the underground water is prevented from coming into contact with the compensator, the compensator is protected and the service life of the compensator is prolonged.
Description
Technical field
The present invention relates to low-temperature water heating sleeve expansion joint insulating structure in a kind of direct-burried.
Background technique
The Totally enclosed heat-preserving mode identical with straight tube adopted in original direct-burried sleeve expansion joint insulation; When compensator moved, keeping warmth space was compressed, and polyurethane foam can expand and damage outer pillar; Groundwater erosion sleeve expansion joint and hot water pipeline cause the insulating structure loss of function.
Summary of the invention
The purpose of this invention is to provide low-temperature water heating sleeve expansion joint insulating structure in a kind of direct-burried.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: low-temperature water heating sleeve expansion joint insulating structure in a kind of direct-burried; The movable end pipe of compensator is set with the outer pillar of movable end outward; Outer pillar one end of movable end is connected with adapter sleeve; The other end is connected on the slide holder, and the fixed end pipe box of compensator is equipped with thermal insulation layer, and thermal insulation layer is set with the outer pillar of fixed end outward; Be provided with rubber corrugated pipe between outer pillar of movable end and the outer pillar of fixed end, outer pillar of movable end and the outer pillar of fixed end upper end are welded with outer sleeve through ring flat-plate.
The movable end pipe of said compensator is provided with the glass yarn heat-preservation cotton.
Said rubber corrugated pipe inside is provided with the glass yarn heat-preservation cotton.
The outer pillar of said fixed end is connected with thermal insulation layer through self tapping screw.
The two ends of said rubber corrugated pipe are connected with the outer pillar of fixed tube through the outer pillar of cuff and movable end respectively.
Low-temperature water heating sleeve expansion joint insulating structure in a kind of direct-burried of the present invention, insulating structure need not connecting tube, and outer pillar need not to adopt variable-diameter structure; Processing technology is simple, and is with low cost, because the thermal insulation layer of fixed end pipe is relatively thin; Therefore inapplicable compensator insulation at high-temperature-hot-water, outer pillar bascule is adopted in the compensator insulation in can only being applied in the low temperature pipe network; Guaranteed compensator in telescopic process, do not damage thermal insulation layer with outside pillar, adopt rubber corrugated pipe in the insulating structure, completely cut off contacting of underground water and compensator; Protect compensator, prolonged the working life of compensator.
Description of drawings
Fig. 1 is a low-temperature water heating sleeve expansion joint insulating structure schematic representation in a kind of direct-burried of the present invention.
Embodiment
As shown in Figure 1; Low-temperature water heating sleeve expansion joint insulating structure in the direct-burried, the movable end pipe 1 outer outer pillar 3 of movable end that is set with of compensator, outer pillar 3 one ends of movable end pipe are connected with adapter sleeve 2; The other end is connected on the slide holder 6; The fixed end pipe 12 of compensator is set with thermal insulation layer 11, and the thermal insulation layer 11 outer outer pillars 13 of fixed end that are set with are provided with rubber corrugated pipe 8 between outer pillar 3 of movable end and the outer pillar 13 of fixed end; The outer pillar 3 of movable end is welded with outer sleeve 9 with outer pillar 13 upper ends of fixed end through ring flat-plate 5; The movable end pipe 1 of compensator is provided with glass yarn heat-preservation cotton 4, and rubber corrugated pipe 8 inside are provided with glass yarn heat-preservation cotton 4, and the outer pillar 13 of fixed end is through the self tapping spiral shell; 10 are connected with thermal insulation layer 11; The two ends of rubber corrugated pipe 8 are connected with the outer pillar 13 of fixed end through the outer pillar 3 of cuff 7 and movable end respectively, and this structure movable end adopts rubber corrugated pipe to be connected with fixed end, and it mainly acts on and is: bellows can freely stretch when the working pipe of compensator produces displacement; Also isolated simultaneously underground water gets into the thermal insulation layer of compensator; With the insulation of bellows interior insulation employing glass silk flosssilk wadding, have certain elastic deformation to guarantee bellows heat-preservation cotton when flexible on the movable end pipe of compensator, the sliding support support that it is hard wood that the sleeve expansion joint intermediate portion is provided with one group of material guarantees that the rigidity of outer pillar is unlikely to subside.
