Abstract

The utility model relates to a ground-buried heat insulation steam water draining well, particularly a fitting of a ground-buried heating power transport pipeline, which comprises a well body, wherein a hand operated water outlet pipe and an automatic water outlet pipe which are associated and connected with a water draining pipe are arranged in the well body; a stop valve is installed on the hand operated water outlet pipe; a steam trap is installed on the automatic water outlet pipe; both heads of the steam trap are respectively connected with the stop valve in series; the well body is an enclosed box body which is formed by the weld of steel plates; the inner wall of each of the steel plates lays a heat-preservation material layer; the heat-preservation material layer is coated by a thin steel plate layer; the outer side of each of the steel plates of the well body is coated with an outer anti-corrosion layer; the bottom of the box body is provided with a water collecting bucket which is connected with the water outlet pipes; the bottom of the water collecting bucket is provided with an artesian water pipe. Because the water draining, the steam trap, a safety valve door and the water collecting bucket are prefabricated into integration with the functions of water discharge, heat preservation and corrosion prevention, the utility model is not only convenient for the purchasing links of users but also for operation sites; the equipment is safe, the water draining quality can be ensured, and the energy-saving efficiency and the service life of pipe fittings can be improved.

Description

Bury the hydrophobic well of the heat insulation steam in ground

Technical field

The utility model relates to the accessory that buries ground heating power conveyance conduit, refers in particular to a kind of hydrophobic well chamber that is used on the direct-burried heat supply pipeline.

Technical background

On the direct-buried steam pipeline commonly used now, hydrophobic well all directly places the face of land, the well body of building by laying bricks or stones is uncovered, it is built-in with manual drainage pipe in parallel and automatic waste pipe, on the manual drainage pipe stop valve is installed, automatically on the waste pipe STEAM TRAP is housed, STEAM TRAP two respectively is connected in series a stop valve, the deficiency that exists is: 1) uncovered structure makes and buries the STEAM TRAP that ground heating power delivery pipe drain pipe is connected, annex unprotect measures such as valve, high temperature vapour of discharging after hydrophobic and the water safety installations that do not catchment, directly enter the atmosphere and the face of land, caused accident potential, also make the life-span of steam trap connection be subjected to influence; 2) automatically waste pipe is consistent with manual drainage pipe caliber, because to bury in the ground conveyance conduit foreign material more, the volume that has is also bigger, directly can't discharge by the manual drainage pipeline of less caliber, has influenced the normal use of equipment when equipment is initial; 3) because part installation unit lacks corresponding installation experience, also make the normal mounting of steam trap connection and operation lack assurance, influence the normal operation of whole tubing.

Summary of the invention

The utility model is just in order to overcome above-mentioned deficiency, a kind of hydrophobic well of the heat insulation steam in ground that buries is provided, by the well chamber with steam trap connection, heat insulation, anticorrosion set one, both made things convenient for user's buying link, also provide convenience for site operation, more make the quality of whole steam trap connection be guaranteed, improved the working life of energy-saving efficiency and pipe fitting, specifically implement like this: bury the hydrophobic well of the heat insulation steam in ground, comprise the well body, the well body is built-in with manual drainage pipe related with drain pipe being of joining and waste pipe automatically, on the manual drainage pipe stop valve is installed, on the waste pipe STEAM TRAP is housed automatically, STEAM TRAP two respectively is connected in series a stop valve, it is characterized in that the well body is the closed box that is welded by steel plate, the steel plate inwall is equipped with adiabator layer, and described adiabator layer is covered by a sheet metal layer, and the well bore steel plate outside scribbles external anti-corrosion layer, bottom half is provided with the drip pan that links to each other with waste pipe, and the drip pan bottom is equipped with the gravity flow water pipe.The utility model is with drain pipe, STEAM TRAP, Safety valve, drip pan, following draining, insulation and the anticorrosion one that is prefabricated in factory; the level that need not to consider construction party can both conveniently be installed and be reliable; enclosed construction provides safety measure; avoided accident potential, also prolonged greatly the working life of equipment simultaneously.

Casing of the present utility model top is welded with the well lid frame for the circumference connecting head on it, be coated with anti-stealing manhole cover on the described well lid frame mouth, when equipment need keep in repair, enters the well body and can operate as long as open anti-stealing manhole cover.

Manual drainage pipe of the present utility model and the automatically rectangular arrangement of waste pipe, when solving device start the blowdown of manual drainage pipe smooth or can't the blowdown problem, the utility model overstriking manual drainage pipe caliber can make initial bigger material discharge smoothly.

The utility model is welded with the angle steel of two fixed manual waste pipes and automatic waste pipe for two drainage pipe fastness in fixing and the reinforcement well chamber in the well chamber, this angle steel and manual drainage pipe are with waste pipe is contour automatically.

The utility model is by drain pipe just, STEAM TRAP, Safety valve, drip pan, draining, insulation and the anticorrosion one that is prefabricated in factory down, both made things convenient for user's buying link, also provide convenience for site operation, device security is reliable, hydrophobic quality is guaranteed, and has improved the working life of energy-saving efficiency and pipe fitting.
