Abstract

The utility model discloses a heat-insulation anti-corrosion drain well chamber, which is mainly composed of a cover plate, a well cover, a drainage pipe, a steam trap, a safety valve and a lower drainage heat-preservation anti-corrosion device. The utility model is characterized in that the drainage pipe, the steam trap, the safety valve, the lower drainage heat-preservation anti-corrosion device and the well chamber are made into integration. The utility model has the advantages of simple structure, the reduction of the purchasing model selection difficulty of users, convenient construction on site, the assurance of the quality of the whole steam trap, the improvement of energy-saving efficiency and the long service life of the pipe fittings.

Description

The hydrophobic well of heat insulating and corrosion chamber

Technical field:

The utility model relates to the hydrophobic well chamber in a kind of direct-burried heat supply pipeline, relates in particular to the hydrophobic well of a kind of heat insulating and corrosion chamber.

Background technique:

Steam trap connection does not have the safety installations of catchmenting on the existing direct-buried steam pipeline, to be connected annex unprotect measures (major part is exposed on the ground) such as back STEAM TRAP, valve with drain pipe.Promptly brought potential safety hazard, also made the life-span of steam trap connection be subjected to influence.Because the problem of telling somebody what one's real intentions are of supply unit and unit in charge of construction, and the part installation unit lack corresponding installation experience, also make the normal operation of steam trap connection lack assurance, influence the normal operation of whole tubing.

Summary of the invention:

Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, has adopted the hydrophobic well of a kind of heat insulating and corrosion chamber.

To achieve these goals, the technological scheme that its technical problem that solves the utility model adopts is, the hydrophobic well of a kind of heat insulating and corrosion chamber, mainly form, be characterized in: drain pipe, STEAM TRAP, Safety valve, draining down, insulation antiseptic and well chamber are made of one by cover plate, well lid, drain pipe, STEAM TRAP, Safety valve, following draining and insulation antiseptic device.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is simple in structure, be skillfully constructed, having reduced the user purchases the type selecting difficulty, has made things convenient for on-the-spot construction, also make the quality of whole steam trap connection be guaranteed, improved the service life of energy-saving efficiency and pipe fitting, the tool promotional value.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is described in further detail.

Accompanying drawing 1 is a cross-sectional view of the present utility model.

Accompanying drawing 2 is the structural representation of looking squarely of the present utility model.

Embodiment

Referring to Fig. 2, the hydrophobic well of heat insulating and corrosion chamber is the casing that steel plate is welded, and reserves one section drain pipe pipeline section 6 in well chamber one side, links to each other with the drain pipe of underground pipe easily.Drain pipe is made a rectangle bypass with two threeways after inserting the well chamber, and at bypass serial connection one automatic drain valve 13, two of drain valve connects two stop valves 12 more automatically, as starting the normal automatic hydrophobic usefulness in back.On the straight tube in parallel, connect a stop valve 12, use as manual drainage blowdown at ordinary times with bypass.Referring to Fig. 1, in the well chamber with drain pipe with the high position on the welding two angle steel 14, drain pipe and valve are fixed on this angle steel.The last drip pan of introducing 10 of drain pipe, drip pan is positioned at bottom, well chamber, the homonymy of drain pipe when inserting the well chamber.By draining gravity line 11 condensed water in the drip pan is discharged at last.The top of well chamber links to each other with cover plate 4 by bolt 5, adopts heat-insulating and sealing circle 3 between cover plate and the well chamber, leaks to prevent steam.The well lid central openings links to each other with steel pipe 2, as the maintenance and inspection well, welds anti-stealing manhole cover 1 above.At last, lay thermal insulating material 9, and cover, do polyureas external anti-corrosion layer 7 in the well bore outside with sheet metal 8 in the well chamber interior walls.

Claims

1, the hydrophobic well of a kind of heat insulating and corrosion chamber, mainly form by cover plate, well lid, drain pipe, STEAM TRAP, Safety valve, following draining and insulation antiseptic device, it is characterized in that: the top of well chamber links to each other with cover plate by bolt, adopt the heat-insulating and sealing circle between cover plate and the well chamber, well lid central authorities offer a hole, link to each other with steel pipe, wherein, the inwall of well chamber is equipped with thermal insulating material, and is covered by steel plate, and the well bore outside is provided with external anti-corrosion layer.
