Abstract
The utility model relates to a direct bury type vacuum heat preservation stream pipe drainage system which comprises a stream supply pipe, inorganic heat preservation materials, a vacuum layer, a coat pipe and etc. The stream supply pipe vertical lower part is melt with a roundness water storage case, which is closely linked with the stream supply pipe, and leaves a space to the water storage case, the coat pipe lower part is melt with a steel pipe as the lower protective cap. The drainage pipe vertically perforates the stream supply pipe and is melt with the stream supply pipe outside wall, the lowermost part inserts into the water storage case. The drainage pipe up part from the protective cap leads out and links to a drainage device and the corresponding water discharge pipeline. When the stream pipeline inside condensed water produced, the condensed water flows into the roundness water storage case, depending on the stream self-pressure can head the condensed water into a conduit pipe, then by the drainage device the water is discharged. The utility model has the wholesome effect that the direct bury type vacuum heat preservation stream pipe inside is directly added with the drainage device, perfectly resolve the problems that the stream pipeline drainage, heat preservation, stream condensed water storage and discharge.
Description
Technical field
The utility model belongs to the heat supply pipeline facility.
Technical background
World oil crisis impels various countries to pay close attention to power-saving technology, and the district heating engineering of taking as the leading factor with cogeneration of heat and power develops rapidly.The Soviet Union and Northern European countries set about research and have promoted the use of directly buried installation heat supply pipeline technology in the seventies from the sixties.Europe, particularly German direct embedment steel pipe technical development is very fast, and Italy, Sweden, Finland are now also developing the high temperature steam pipeline directly buried technology.Domestic direct-buried steam pipe laying technology is from late nineteen eighties, and the directly-buried thermal insulation pipes that adopts is the compound heat preservation structure at present, and does not consider the hydrophobic problem of steam line.When but steam line arrives each user at delivering vapor, on the way because of radiation loss or pressure degradation reason, will have a large amount of water of condensation to produce, this will influence the smooth delivery of power of steam.How getting rid of these water of condensation raising delivering vapor quality is present assistant officer difficult problems to be solved.
Summary of the invention
The purpose of this utility model provides a kind of direct buried type vacuum insulation draining apparatus for steam conduit.
Structural principle of the present utility model as shown in drawings.Direct buried type vacuum insulation draining apparatus for steam conduit has steam transmitting pipe (1), inorganic heat insulation material (2), vacuum layer (3), last protective cap (4); outer sleeve (5), conduit pipe (6), circular water collecting box (7); following protective cap (8), endshield (9), STEAM TRAP (10) etc.Below welding circular water collecting box (7) perpendicular to steam transmitting pipe (1) is welded with protective cap (8) down on the outer sleeve (5) of water collecting box (7) below, water collecting box (7) communicates with steam transmitting pipe (1).Conduit pipe (6) vertically passes steam transmitting pipe (1), and insert in the water collecting box (7) its lower end, and the upper end is drawn from last protective cap (4) and is connected to STEAM TRAP (10) and pipeline, and the outer wall welding of middle part and steam transmitting pipe (1) is fixing.Last protective cap (4) lower end and outer sleeve (5) welding, upper end and conduit pipe (6) welding.Steam transmitting pipe (1) outsourcing inorganic heat insulation material (2) also leaves vacuum layer (3), and outer sleeve (5) adopts the steel pipe manufacturing.The Circular Plate that endshield (9) adopts the polyvinyl chloride material to make is with the outer and inner tube bituminous seal.Its objective is the infiltration that prevents draining apparatus for steam conduit moisture in transportation or installation process, (when imbedding installation, endshield being dismantled).When having water of condensation to produce in the steam line, just can flow in the circular water collecting box (7), rely on the pressure of steam self water of condensation can be headed into conduit pipe (6), discharge by STEAM TRAP (10) again.
The beneficial effects of the utility model are directly to add a steam trap connection in direct buried type vacuum insulation steam line, have solved problems such as the assembly of hydrophobic, insulation, steam condensate of steam line and discharging more satisfactoryly.
Description of drawings
The accompanying drawing left side is structural principle of the present utility model (main looking) figure, and the right side is a side view.1-steam transmitting pipe among the figure, 2-inorganic heat insulation material, 3-vacuum layer, the last protective cap of 4-, 5-outer sleeve, 6-conduit pipe, 7-water collecting box, protective cap under the 8-, 9-endshield, 10-STEAM TRAP.
Specific embodiment
Steam transmitting pipe of the present utility model (1) adopts manufacturings such as steel pipe, and length is 700mm, diameter of steel tube 219mm.The thickness of inorganic heat insulation material (2) is 60～100mm.The thickness of vacuum layer (3) is 10～100mm.It is 300mm that outer sleeve (5) adopts its length of steel pipe, and diameter is 478mm.Endshield (9) is a polyvinyl chloride rounding ring flat-plate, with outer and inner tube with bituminous seal when welding (construction dismantle).Conduit pipe (6) is used seamless steel pipe, diameter 33mm.Open the hole that a diameter is about 100mm on the top of outer sleeve (5).Also having diameter on the top of steam transmitting pipe (1) is the 34mm hole.The bottom of steam transmitting pipe (1) communicates with circular water collecting box (7), so have the hole of diameter 70mm, it is the bottom welding of steel pipe and the steam transmitting pipe (1) of 108mm that circular water collecting box (7) can adopt diameter, the round plate soldering and sealing of its lower end mouth.For giving water collecting box (7) slot milling, the hole that to open an about diameter in outer sleeve (5) bottom be 150mm.Outer sleeve (5) is enclosed within on the steam transmitting pipe (1), conduit pipe (6) is inserted from outer sleeve (5) top macropore, from the upper and lower hole of steam transmitting pipe (1), pass, insert bottom in the water collecting box (7).Conduit pipe (6) and steam transmitting pipe (1) are welded from the top of outer sleeve (5) with welding gun.Have on the position of 150mm macropore in outer sleeve (5) bottom simultaneously, weld diameter is the following protective cap (8) of steel pipe conduct of 159mm, the round plate soldering and sealing of its lower end mouth.Open on the position in 100mm hole protective cap in the welding (4) on outer sleeve (5) top.Last protective cap can be with the steel pipe of diameter 100mm, and the protective cap upper end-hole is welded with round plate, but will draw conduit pipe (6) and be connected with STEAM TRAP (10) and corresponding waste pipe.
When imbedding installation, steam direct-buried formula vacuum thermal-insulating pipeline, the vacuum heat-preserving steam trap connection is set by designing requirement.The vacuum thermal-insulating pipeline internal fixation section that direct buried type vacuum insulation draining apparatus for steam conduit and two ends have no vent welds together, and forms vacuum layer and extraneous completely cutting off.Behind the pipeline pressure test, on insulation pipe, connect vacuum pump, extract air and moisture in the cavity, form vacuum heat-preserving.
