Described cylindrical shell bottom is provided with waste pipe.
Described cylindrical shell top is provided with the suction chamber pressure gauge.
Described cylindrical shell discharge chamber one side is provided with overflow pipe, and the overflow pipe position is higher than the dividing plate bottom surface.
Described overflow pipe is connected with the dust flue of hydathode respectively with waste pipe.
Described seal chamber can be rectangular cavities, can be also other shape cavity.
Described intake pipe can be arranged on the gas inlet side of cylindrical shell, also can be arranged on the gas exit side of cylindrical shell.
Compared with prior art, the invention has the beneficial effects as follows:
Apparatus of the present invention reasonable in design, simple and safe operation, the phenomenon of gas leakage while having avoided using blind plate, provide safety guarantee to the personnel of execute-in-place.
The accompanying drawing explanation
Fig. 1 is the structural representations of apparatus of the present invention while normally carrying coal gas;
The A-A that Fig. 2 is Fig. 1 is to view;
View when Fig. 3 is apparatus of the present invention cut-out coal gas.
In figure: 1, gas inlet valve 2, gas inlet pipe 3, suction chamber pressure gage valve 4, suction chamber pressure gauge 5, dividing plate 6, separator pressure table 7, separator pressure meter valve 8, control valve valve 9, intake pipe valve 10, intake pipe 11, control valve 12, gas outlet tube 13, gas exit valve 14, overflow pipe 15, waste pipe 16, waste pipe valve 17, dust flue 18, overflow pipe valve 19, hydathode 20, cylindrical shell
Embodiment
A kind of gas cutting-off machine, as shown in FIG. 1 to 3, comprise cylindrical shell 20, dividing plate 5 and intake pipe 10, cylindrical shell 20 both sides are provided with gas inlet pipe 2 and gas outlet tube 12, cylindrical shell 20 middle parts are provided with dividing plate 5, dividing plate 5 is divided into suction chamber and two spaces of discharge chamber by cylindrical shell 20, and cylindrical shell 20 tops are provided with suction chamber pressure gauge 4, and whole cylindrical shell 20 is all-sealed structure.In dividing plate 5, be rectangular seal cavity or other shape seal chamber, dividing plate 5 tops and both sides are exposed to respectively outside cylindrical shell 20, dividing plate 5 bottom surfaces lower than gas inlet pipe 2 and gas outlet tube 12 and and cylindrical shell 20 bottoms between leave space, the part that dividing plate 5 exposes cylindrical shell 20 is provided with separator pressure table 6 and control valve 11, cylindrical shell 20 is provided with intake pipe 10, intake pipe 10 can be arranged on the gas inlet side of cylindrical shell 20, also can be arranged on the gas exit side of cylindrical shell 20.Cylindrical shell 20 bottoms are provided with waste pipe 15, and discharge chamber one side of cylindrical shell 20 is provided with overflow pipe 14, and overflow pipe 14 positions are higher than dividing plate 5 bottom surfaces, and overflow pipe 14 is connected with the dust flue 17 of hydathode 19 respectively with waste pipe 15.
State when gas pipe line is normally carried coal gas as shown in Figure 1, now, gas inlet valve 1, gas exit valve 13, suction chamber pressure gage valve 3, separator pressure meter valve 7, waste pipe valve 16, overflow pipe valve 18 are all opened; Control valve valve 8, intake pipe valve 9 are all closed, and the coal gas that pipeline is carried enters cylindrical shell 20 by gas inlet, enters the seal chamber opposite side along dividing plate 5 bottoms, then discharges from gas exit.Now, if in coal gas with ponding, ponding flows into gas pipeline drainers 19 by the waste pipe 15 of cylindrical shell 20 bottoms, finally by hydathode 19 outlets, is emitted.In the process of carrying coal gas, if separator pressure table 6 is designated as null value, illustrate that dividing plate 5 is without leak source, if separator pressure table 6 indicated value is greater than zero, illustrate that the dividing plate 5 of seal chamber has leak source, the maintenance of stopping the supple of gas or steam, until normal operation.
While needing to cut off gas operation, as shown in Figure 3, gas inlet valve 1, gas exit valve 13, control valve valve 8, waste pipe valve 16 are all closed; Suction chamber pressure gage valve 3, separator pressure meter valve 7, overflow pipe valve 18 are all opened.Now, add water by intake pipe 10, and guarantee that the water surface is higher than the seal chamber bottom, when having water to flow out from overflow pipe 14, illustrate that the water yield added meets the demands, now, even gas inlet valve 1 has leakage, coal gas is also disconnected by the water resistance in cylindrical shell 20, and then has reached the purpose of cutting off coal gas fully.In this process, if find, the numerical value of separator pressure table 6 is greater than zero, illustrates that seal chamber has leak source, now, open control valve valve 8, by control valve 11, add high pressure water, until the numerical value of separator pressure table 6 is more than or equal to the numerical value of suction chamber pressure gauge 4, prevent that coal gas from passing from dividing plate 5.After treating that gas operation completes, recover the working state that normal coal gas is carried.
