Abstract

The utility model discloses a full-automatic dewatering and draining device for a directly-buried steam pipe, which comprises a liner and an outer sleeve, wherein the liner is installed in the outer sleeve; a heat insulation layer is filled between the liner and the outer sleeve; a trimming flow guide barrel outwards extends from the upper part in the liner; two ends of the lower part of a three-way pipe extend into the trimming flow guide barrel; the upper end of the three-way pipe penetrates through the liner to extend out of the outer sleeve; a water collection barrel downwards extends from the bottom of the liner; the lower end of a drain pipe extends into the bottom of the water collection barrel; and the upper end of the drain pipe penetrates through the liner to extend out of the outer sleeve. The full-automatic dewatering and draining device for the directly-buried steam pipe, which is disclosed by the utility model, has the characteristics of small land occupation, can automatically dewater and drain and is safe and reliable.

Description

The full-automatic hydrophobic drainage means of a kind of direct-buried steam pipeline

Technical field

The utility model belongs to heat distribution pipeline drainage field, especially relates to the full-automatic hydrophobic drainage means of a kind of direct-buried steam pipeline.

Background technique

On the heat distribution pipeline line, must be provided with draining well and drainage means, the now general hydrophobic drainage means of reinforced concrete construction deep-well that adopts, because of its floor space big; Need be equipped with vehicle and special messenger every day and carry out artificial pump drainage water; Maintenance cost is high, and potential safety hazard is big, the waterproof difficulty; Rainy season or underground water rise and very easily produce the indoor pipe phenomenon of boiling of hydrophobic well, reduce pipe network working life.

Summary of the invention

The purpose of the utility model is to improve the deficiency of prior art and provides a kind of automatic draining direct-buried steam pipeline hydrophobic, that floor space is little, safe and reliable full-automatic hydrophobic drainage means.

The purpose of the utility model is achieved in that the full-automatic hydrophobic drainage means of a kind of direct-buried steam pipeline, is made up of inner bag and outer sleeve; Be characterized in that inner bag is installed in the outer sleeve; Be filled with thermal insulation layer between inner bag and outer sleeve, the top in the inner bag is outward extended with side cut conductance tube, and side cut conductance tube is stretched at the two ends, bottom of three-way pipe; The upper end is passed inner bag and is stretched out outer sleeve; The bottom of inner bag is extended with Water collecting tube downwards, and the lower end of waste pipe extend into the Water collecting tube bottom, and the upper end is passed inner bag and stretched out outer sleeve.

In order further to realize the purpose of the utility model, can be that side cut conductance tube, Water collecting tube are provided with thermal-protective coating outward.

Compared with present technology the utility model has following distinguishing feature and good effect: the utility model adopts inner bag to be installed in the outer sleeve, is filled with thermal insulation layer between inner bag and outer sleeve, and the top in the inner bag is outward extended with side cut conductance tube; Side cut conductance tube is stretched at the two ends, bottom of three-way pipe, and the upper end is passed inner bag and stretched out outer sleeve, and the bottom of inner bag is extended with Water collecting tube downwards; The lower end of waste pipe extend into Water collecting tube bottom, and the upper end is passed inner bag and stretched out outer sleeve, and the upper end of three-way pipe is passed inner bag and stretched out outer sleeve and be linked on the Water collecting tube bottom the heat distribution pipeline band draining heat insulation type internal fixation pier like this; Just directly flow into side cut conductance tube to ducted condensation ponding through three-way pipe, along the Water collecting tube of wall of inner container inflow inner bag bottom, ponding flows down along wall of inner container; Steam and ponding bump in the inner bag have been avoided; Because this device is near heat distribution pipeline, the inner bag inside temperature is higher, under the pressure of ponding steam in inner bag of entering Water collecting tube; Get into waste pipe through the waste pipe lower end; The upper end ground plane white-out water device of waste pipe has so just been discharged ponding automatically, and the thermal insulation layer between inner bag and outer sleeve has kept the temperature in the inner bag; Side cut conductance tube, Water collecting tube are provided with thermal-protective coating outward, form heat bridge to prevent that steam condensate from storing between inner bag and the outer sleeve; The utility model can be discharged ponding and condensed water automatically, need not artificial pump drainage water, has that volume is little, simple in structure, installation and maintenance are easy, safety reliability is high, need not powered attendant-controlled wheelchairs characteristics.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

Fig. 1 is a kind of structural representation of the utility model.

Fig. 2 is the another kind of structural representation of the utility model.

Embodiment

Embodiment 1, and the full-automatic hydrophobic drainage means of a kind of direct-buried steam pipeline is with reference to Fig. 1; Be that inner bag 1 is installed in the outer sleeve 6,6 of inner bag 1 and outer sleeves are filled with thermal insulation layer 7, and the top in the inner bag 1 is outward extended with side cut conductance tube 4; Side cut conductance tube 4 is stretched at the two ends, bottom of three-way pipe 2; The upper end is passed inner bag 1 and is stretched out in the Water collecting tube that outer sleeve 6 inserts heat distribution pipeline band draining heat insulation type internal fixation piers bottom, and the bottom of inner bag 1 is extended with Water collecting tube 5 downwards, and the lower end of waste pipe 3 extend into Water collecting tube 5 bottoms; The upper end is passed inner bag 1 and is stretched out outer sleeve 6 ground plane white-out water devices, and this constitutes a kind of structure of the utility model.

Embodiment 2, and the full-automatic hydrophobic drainage means of a kind of direct-buried steam pipeline with reference to Fig. 2, is on embodiment 1 basis, side cut conductance tube 4, the Water collecting tube 5 outer thermal-protective coatings 8 that are provided with, and other and embodiment 1 are identical.

When using the utility model; The upper end of three-way pipe 2 is passed inner bag 1 and is stretched out on the Water collecting tube that outer sleeve 6 is linked into heat distribution pipeline band draining heat insulation type internal fixation pier bottom, just directly flows into side cut conductance tubes 4 to ducted condensation ponding through three-way pipe 2, flows into the Water collecting tube 5 of inner bag 1 bottom along inner bag 1 wall; Because this device is near heat distribution pipeline; Inner bag 1 inside temperature is higher, under the pressure of ponding steam in inner bag 1 of entering Water collecting tube 5, gets into waste pipe 3 through waste pipe 3 lower ends; The upper end ground plane white-out water device of waste pipe 3 has so just been discharged ponding automatically.。
