Abstract
The invention discloses a novel full-embedding type expansion joint. The novel full-embedding type expansion joint adopts the technical scheme that the novel full-embedding type expansion joint comprises a corrugated pipe and a flow guide pipe, wherein the two ends of the corrugated pipe are respectively connected with a connecting pipe, the flow guide pipe is arranged in the corrugated pipe, the periphery of the corrugated pipe is provided with an outer protecting sleeve, the outer protecting sleeve is sealed and connected with the connecting pipe at the left end through a welding ring, a heat insulation sleeve is arranged in an interlayer between the outer protecting sleeve and the connecting pipe at the right end, and the right end port of the outer protecting sleeve is sealed and fixedly arranged on the heat insulation sleeve by a pressing flange. The expansion joint has the beneficial effects that the structure is simple and reasonable, the exterior is provided with the outer protecting sleeve, and the damage to the expansion joint by the heavy pressure of the soil is avoided; the interlayer is provided with the heat insulation sleeve, so the freezing cracking of the expansion joint under the low-temperature environment is avoided; the flow guide pipe and the corrugated pipe are made of stainless steel material, the heat insulation filling material adopts high-density polyethylene or foaming polyurethane, and the other parts are made of carbon steel, so compared with other materials, the corrosion-resistant, high temperature-resistant, low temperature-resistant and pressure-resistant performances are better.
Description
Technical field
The present invention relates under ground piping expansion joint application used, relate in particular to a kind of novel type expansion joint that entirely buries.
Background technique
In urbanization layout, the use of under ground piping is very extensive.The expansion joint being applied under ground piping there will be various problem in different places.The expansion joint being embedded in acid soil or liquid is easily corroded; Be embedded in the expansion joint of cold area easily by bursting by freezing; Be embedded in expansion joint under face deeper and crush easily etc. problem.
Summary of the invention
In order to address the above problem, the object of this invention is to provide a kind of novel type expansion joint that entirely buries, this expansion joint has oversheath outward, in have lagging, and select 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 novel type expansion joint that entirely buries, and it comprises the bellows 3 of two ends connecting tubes 1, is located at the honeycomb duct 2 of described bellows 3 inside.Described bellows 3 be peripherally equipped with oversheath 4, described oversheath 4 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 4 and right-hand member, lagging 5 is housed, the right output port of described oversheath 4 is used supported flange 7 that its sealing is fixed on described lagging 5.
Further, the heat insulating stuffing of described lagging 5 can be high density polyethylene (HDPE) or polyurethane foam.
Further, described supported flange 7 is fastening by bolt 8.
Further, the described novel type expansion joint that entirely buries is that metallic material is made, and described honeycomb duct 2 wherein and bellows 3 are stainless steel material making.
The present invention has following beneficial effect: the present invention is simple and reasonable, is provided with oversheath outward, and protection expansion joint avoids damaging under earth weight; Mesosphere is provided with lagging, can prevent under low temperature environment expansion joint bursting by freezing.And in the present invention, honeycomb duct, bellows adopt stainless steel material, heat insulating stuffing adopts high density polyethylene (HDPE) or polyurethane foam, other component adopt carbon steel, and these materials are with respect to other materials, and corrosion-resistant, high temperature resistant, low temperature resistant, compression resistance is all more intrepid.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
With reference to accompanying drawing 1 description of symbols: 1, take over 2, honeycomb duct, 3, bellows, 4, oversheath, 5, lagging, 6, weld-ring, 7, supported flange, 8, bolt.
A kind of novel type expansion joint that entirely buries of the present invention, it is the sealed environment that is added oversheath and lagging and formed a resistance to compression, insulation by conventional expansion joint.Specific operation are: the embedded honeycomb duct 2 of bellows 3 of two ends connecting tubes 1, the peripheral oversheath 4 of installing.Described oversheath 4 passes through weld-ring 6 seal weldings with the described adapter 1 of left end.Between the interlayer of the described adapter 1 of described oversheath 4 and right-hand member, lagging 5 is housed, seal welding between described lagging 5 and described adapter 1.The right output port of described oversheath 4, by the fastening supported flange 7 of bolt 8, is fastened on described lagging 5 peripheries by its sealing.The heat insulating stuffing of described lagging 5 can be high density polyethylene (HDPE) or polyurethane foam.
The described novel type expansion joint that entirely buries is that metallic material is made, and described honeycomb duct 2 wherein and bellows 3 are stainless steel material making.Adapter 1, oversheath 4, lagging 5, weld-ring 6, supported flange 7 materials can adopt carbon steel or other metals.Generally speaking, the cost performance of carbon steel is higher.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other amendments that those of ordinary skill in the art make technological scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
