Abstract
The invention discloses a heat-preserving waterproof fully-buried expansion joint. The technical scheme is as follows: the heat-preserving waterproof fully-buried expansion joint comprises a working corrugated pipe, a guide pipe and a protective corrugated pipe, wherein the left end of the working corrugated pipe is connected with an adapter pipe, the guide pipe is arranged in the working corrugated pipe, the protective corrugated pipe is axially connected with the working corrugated pipe, the junction of the working corrugated pipe and the protective corrugated pipe is provided with a guide plate, the right end of the working corrugated pipe is provided with a baffle plate, an outer jacket is installed on the periphery of the guide plate, the outer jacket is connected with the adapter pipe on the left end in a sealing manner through a soldering ring, a heat-preserving sleeve is installed between the outer jacket and a sandwich layer of the adapter pipe on the right end, and the right port of the outer jacket is fixed on the heat-preserving sleeve in a sealing manner by utilizing a compression flange. The heat-preserving waterproof fully-buried expansion joint has the beneficial effects that the structure is simple and reasonable, and the expansion joint is provided with the outer jacket having the waterproof function and the heat-preserving sleeve having the heat-preserving function; moreover, an anticorrosive, high-temperature-resisting and pressure-resisting material is selected, so that the service life is long, the frequent maintenance is not needed, and a great amount of manpower and material resource can be saved.
Description
Technical field
The present invention relates under ground piping expansion joint application used, relate in particular to a kind of type that entirely buries expansion joint of thermal-insulating waterproof.
Background technique
Along with industrialized fast development, environmental pollution is also more and more serious.In water, the corrosive material that contains in soil is many, the pipeline of underground installation need to overhaul often, to guarantee its normal work, engineering is huge, cost is also high.
Summary of the invention
In order to address the above problem, the object of this invention is to provide a kind of type that entirely buries expansion joint of thermal-insulating waterproof, this expansion joint has been provided with the oversheath of waterproof action, plays the lagging of insulation effect, and selects the material corrosion-resistant, high temperature resistant, crushing resistance is strong.
To achieve these goals, technological scheme of the present invention is achieved in that a kind of type that entirely buries expansion joint of thermal-insulating waterproof, it comprises the work bellows 3 of left end connecting tubes 1, be located at the honeycomb duct 2 of described work bellows 3 inside, the protection bellows 4 being axially connected with described work bellows 3, described work bellows 3 and described protection bellows 4 joints are provided with guide plate 10, described work bellows 3 right-hand members are provided with baffle plate 11, be peripherally equipped with oversheath 5 at described guide plate 10, described oversheath 5 is tightly connected by weld-ring 6 with the described adapter 1 of left end, between the interlayer of the described adapter 1 of described oversheath 5 and right-hand member, lagging 9 is housed, the right output port of described oversheath 5 is used supported flange 7 that its sealing is fixed on described lagging 9.
Further, the heat insulating stuffing of described lagging 9 can be high density polyethylene (HDPE) or polyurethane foam.
