Description
Technical field
The utility model is related to a kind of heat supply pipeline equipment, and in particular to a kind of totally-enclosed wader of heat supply network buried pipe
Put.
Background technology
Heat-net-pipeline is passing through the area city such as road, river course, often take it is buried lay, the buried pipe standpipe laid is being applied
Man-hour is often only higher by 1 to 2 meters of nature Horizon, and arranges on aerial pipeline standpipe rainhat, and rainhat typically uses sheet metal
Make ,-the 5mm of thickness 3, rainhat makes tapered, completes and coats anti-corrosion material, by the inner ring of rainhat of three band irons
Gu also on heat-net-pipeline, outer is generally more than the -10cm of buried pipe outer tube 5, can block the rainwater of major part, prevent rain
Water immersion underground pipe insulation, destroys insulation material heat-insulating property, in actual motion, the phenomenon expanded with heat and contract with cold because having occurs, extremely
Make rainhat occurs often to deviate from dash position, under rainstorm weather state, there is part rainwater to immerse buried heat-net-pipeline
Heat-insulation layer, be heated after evaporate, partly can buried pipe outer tube export discharge, this can be just seen after rainstorm weather often
Underground pipe outer tube emits vapour phenomenon, and some another meeting is in outer casing wall condensation, because outer tube is far below close to geology temperature
Heat-net-pipeline pumped (conveying) medium temperature, condensate is back in heat-insulation layer again, again by thermal evaporation, and is condensed in outer sleeve inner wall,
Thermal discharge is set to geology during condensation, here it is the heat bridge phenomenon that oneself is formed in buried pipe, causes thermal loss.Separately
Outside, because there is more regions to belong to low-lying land, ponding can be formed in Heavy Rainfall Process, and is possible to flood occur, when flood exceeds
During buried pipe outer tube, just there is substantial amounts of flood immersion buried pipe, cause heat supply beach to melt, even if at this moment by pipeline medium
Heat drying insulation is also useless, because the insulation material of immersion has lost heat insulation effect, and along with residual moisture content is more, heat bridge is non-
Chang great, the heat loss put into operation is very big, very uneconomical, and this will change buried pipe, and this will result in very big warp
Ji changes mistake, and causes heat user also to have very big loss with also not upper heat heat user.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of totally-enclosed water-tight device of heat supply network buried pipe, by rain-proof
Cap inner ring sealing welding sets corrugated stainless steel tubing on heat-net-pipeline between outer tube and rainhat, and by stainless steel wave
The line pipe two ends sealing welding between overcoat tube end, rainhat respectively so that it is complete that heat supply network buried pipe is laid under ground portion
Closing avoids the intrusion of rainwater.
The utility model is achieved through the following technical solutions：
A kind of totally-enclosed water-tight device of heat supply network buried pipe, including heat supply network buried pipe, the heat supply network buried pipe outer wall
Heat-insulation layer is laid with, the heat-insulation layer outer cover positioned at subsurface is equipped with outer tube, and the outer tube two ends are above ground level, positioned at outer
Rainhat is connected with buried heat-net-pipeline above sleeve pipe, it is characterised in that：The rainhat inner ring and heat supply network buried pipe
Outer wall is tightly connected, and bellows is provided between the rainhat and outer tube, and described bellows one end is sealed with rainhat to be connected
Connect, the other end is connected with outer tube end part seal, airway tube is welded with the outer tube, the airway tube free end bends court
Earthward..
The utility model further improvement project is that the bellows is corrugated stainless steel tubing.
The utility model further improvement project is to be provided with valve on the airway tube.
The utility model further improvement project is, the rainhat, bellows, outside the outer tube of part above ground level
Heat-insulation layer is laid with wall.
The utility model compared with prior art, has the following advantages that：
First, the utility model by rainhat inner ring sealing welding on heat supply network buried pipe, it is to avoid rainwater penetrate into.
2nd, the utility model is provided with corrugated stainless steel tubing between rainhat and outer tube, and by corrugated stainless steel tubing
Two ends are connected with rainhat outer, outer tube Seal welds for ends respectively so that rainhat, corrugated stainless steel tubing, overcoat are tubular
Into a sealing structure, effectively prevent rainwater from penetrating into heat-insulation layer.
3rd, the utility model connects outer tube sleeve and rainhat using corrugated stainless steel tubing, meets and meets the buried pipe
Deviation expansion, it is to avoid occur pipeline lose.
4th, the utility model is welded with airway tube in outer tube sleeve, rainhat, stainless steel wave after effective guarantee is closed
The discharge of hot air and the suction of cold conditions air in line pipe, outer tube.
5th, airway tube free end is bent towards ground by the utility model, it is to avoid rainwater occur when rainy enters pipe
Road.
6th, the utility model is provided with valve on airway tube, was put into operation Cheng Qian in heat-net-pipeline, valve is opened, treated
Pipeline is in running status, puts into operation after the normal air discharge in closed structure, closes valve；Disabled in heat-net-pipeline cold
But during, valve is opened, treats that air sucks closed structure, valve is closed after heat-net-pipeline cooling, prevented in air
Steam enters closed structure.
7th, the utility model is laid with insulation in rainhat, bellows, the overcoat pipe outer wall of part above ground level
