Abstract
The utility model relates to a gas leakage-prevention drainer comprising a gas drainer body and a leakage preventer, wherein the leakage preventer consists of a cylinder, the bottom of the gas drainer body is communicated with the bottom of the cylinder by a connecting pipeline, the leakage preventer further comprises a plurality of through pipes, a piston cover, a partition plate and an indicating rod, the plurality of through pipes are uniformly arranged at the bottom of the cylinder, the piston cover is arranged at the upper part of the plurality of through pipes and is tightly contacted with the inner wall of the cylinder, the partition plate is fixed on the inner wall of the cylinder at the upper part of the piston cover, a vent hole is arranged in the middle of the partition plate, the lower end of the indicating rod is fixed on the piston cover, the upper end of the indicating rod penetrates through the vent hole and extends out of the cylinder, and a drain pipe is connected on the side wall at the top of the cylinder and communicated with the gas drainer body. The gas leakage-prevention drainer has the advantages of being simple in structure, good in effect of preventing gas leakage, and capable of being recycled as water enters in the gas drainer body through the drain pipe.
Description
Technical field
The utility model relates to a kind of coal gas anti-leak hydathode.
Background technique
When carrying the CO that blast furnace produced, on pipeline, all be provided with a drainage device at a certain distance at present, but this drainage device, generally can only discharge impurity contained in the coal gas and water, but the excess pressure for coal gas causes pipeline breaking, is not solved at all.Anti-leakage gas drainage device of the prior art, comprise coal gas drainer and the leakage preventer that is connected with the anti-leak hydathode, leakage preventer comprises cylindrical shell, indicating arm, baffle plate and be located at baffle plate with the floating drum in the lower cylinder body utilizes the gas pressure fluctuation, when the coal gas drainer water seal is breakdown, water is discharged from drainage pipe, drawdown, floating drum sinks, and valve is closed automatically, thereby seal coal gas, prevent that coal gas from leaking in a large number, but under the situation of water seal low excessively (serious water shortage), valve can not be closed fully, produce gas leakage, cause potential safety hazard, the water by drainage pipe discharges does not obtain recycling, the wasting of resources, this structure are also complicated.Therefore, need provide a kind of new technological scheme to solve the problems referred to above.
The model utility content
The purpose of this utility model provide a kind of simple in structure, prevent the coal gas anti-leak hydathode that gas leakage is effective.
The technical solution adopted in the utility model:
A kind of coal gas anti-leak hydathode, comprise coal gas drainer body and leakage preventer, described leakage preventer comprises cylindrical shell, described coal gas drainer body bottom is communicated with the cylindrical shell bottom by connecting tube, described leakage preventer also comprises many siphunculus, piston cap, dividing plate and indicating arm, described many siphunculus evenly are located at the cylindrical shell bottom, described piston cap places many siphunculus tops and closely contacts with cylinder inboard wall, described piston upper part of the cover cylinder inboard wall is fixed with dividing plate, have ventilating hole in the middle of the described dividing plate, described indicating arm lower end is fixed on the piston cap, described indicating arm upper end is passed ventilating hole and is extended to the cylindrical shell outside, described cylindrical shell top sidewall is connected with waste pipe, and described waste pipe is communicated with the coal gas drainer body.
Described siphunculus number is the 4-10 root.
The beneficial effects of the utility model: after coal gas enters cylindrical shell, utilize in the closed container gas to rise and occupy the space principle, water level rises, and coal gas enters siphunculus, when gas pressure surpasses certain value, the coal gas that enters siphunculus makes piston cap upwards withstand ventilating hole, prevented the leakage of coal gas, indicating arm rises simultaneously, gives warning effect, water enters in the coal gas drainer body by waste pipe, reusable edible.

Fig. 1 is a structural representation of the present utility model.
Wherein, 1, cylindrical shell, 2, ventilating hole, 3, waste pipe, 4, connecting tube, 5, the coal gas drainer body, 6, indicating arm, 7, siphunculus, 8, piston cap, 9, dividing plate, 10, leakage preventer.
Embodiment
As shown in Figure 1, a kind of coal gas anti-leak hydathode of the present utility model, comprise coal gas drainer body 5 and leakage preventer 10, leakage preventer 10 comprises cylindrical shell 1, coal gas drainer body 5 bottoms are communicated with cylindrical shell 1 bottom by connecting tube 4, leakage preventer 10 also comprises 8 siphunculus 7, piston cap 8, dividing plate 9 and indicating arm 6,8 siphunculus 7 evenly are located at cylindrical shell 1 bottom, piston cap 8 places 8 siphunculus 7 tops and closely contacts with cylindrical shell 1 inwall, cylindrical shell 1 inwall on piston cap 8 tops is fixed with dividing plate 9, have ventilating hole 2 in the middle of the dividing plate 9, indicating arm 6 lower ends are fixed on the piston cap 8, indicating arm 6 upper ends are passed ventilating hole 2 and are extended to cylindrical shell 1 outside, and cylindrical shell 1 top sidewall is connected with waste pipe 3, and waste pipe 3 is communicated with coal gas drainer body 5.
After coal gas enters cylindrical shell 1, utilize in the closed container gas to rise and occupy the space principle, water level rises, and coal gas enters siphunculus 7, when gas pressure surpasses certain value, the coal gas that enters siphunculus 7 makes piston cap 8 upwards withstand ventilating hole 2, prevented the leakage of coal gas, indicating arm 6 rises simultaneously, gives warning effect, water enters in the coal gas drainer body 5 by waste pipe 3, reusable edible.
Claims (2)
