Description
Technical field
The utility model relates to the water-sealing valve that is used to cut off coal gas in the pipeline.
Background technique
Gas pipe line water seal cut-off valve of the prior art is that domestic and international iron and steel enterprise generally uses a pipeline kind equipment, and its advantage is that making simple, easy to use is a kind of good pipeline supporting facility that can reliably cut off coal gas in the gas pipe line.But its shortcoming is that manifold pressure fluctuates or the low inferior reason of water level will leakage gas.
Chinese patent ZL 200420022383.4 " a kind of gas pipe line water-sealing valve ", the solution that it is more successful water-sealing valve leakage gas problem, its function is, can rely on leakage preventer to check gas leakage at ordinary times, it is low that water level takes place after the water seal water shutoff, can automatic water supplement, in case take place gas leakage up and down draining can effectively control leakage.
Referring to Fig. 1, it is a kind of coal gas water-sealing valve, and wherein 1a is the water-sealing valve body, 2a is a drain opening, 3a is an outlet pipe, and 5a is a sewage pipe, and 51a is a communication valve, 6a is a displacement can, 7a is a valve, and 8a is a secondary valve, and 9a is supply pipe, the 91a main valve that feeds water, 10a is water-adding pipe, 101a communication valve, and 11a is a gas pipe.
Its working principle is, coal gas is by water-sealing valve body 1a circulation, condensed water among the gas pipe 11a and foreign material are discharged to hydathode 6a through what secondary valve 7a was set with a valve 8a, the hydathode working condition is to rely on the effective height of setting to carry out draining, condensed water is discharged to sewage pipe 5a through communication valve 51a, because the time can appearring in the pipeline operation, problem such as pressure surge cause the destruction of the effective height H of water shutoff that the problem of leakage gas takes place, working principle when coal gas is cut off in water seal is: close communication valve 4a, open feedwater main valve 9a to water-sealing valve body 1a water-filling, flowing full promptly reaches the effective height of its water shutoff to waste pipe 2a, for the water shutoff safety that guarantees water-sealing valve is opened moisturizing communication valve 10a, the timely moisturizing when it guarantees pressure surge.Close feedwater main valve 9a when opening coal gas, open communication valve 4a and emit the interior water of water-sealing valve.The shortcoming of this water-sealing valve is, water-sealing valve is opened when normal ventilating coal gas is worked, rely on hydathode to get rid of the condensed water of pipeline automatically, but, let alone gas leakage and the gas poisoning that causes has been undisputable fact owing to reasons such as pressure surge in the gas pipe line cause the displacement can water level low and can't judge and check.
Summary of the invention
The purpose of this utility model is to provide a kind of gas pipe line water-sealing valve that can observed stage, can prevent from the gas pipe line water seal cut-off valve to cause because of water level is low accident to leak the coal gas effectively.
For achieving the above object, the technical solution of the utility model is,
A kind of gas pipe line water-sealing valve that can observed stage, it is installed in the gas pipe line, and it comprises, the water-sealing valve body, U type structure is arranged in the gas pipe line, and U type structure bottom is provided with waste pipe, and waste pipe is provided with first control valve, second control valve; Displacement can is arranged under the waste pipe; Intake pipe is connected in the water seal valve body, which is provided with water supply control valve; Outlet pipe is connected in displacement can; Also be provided with an observations of water stage mechanism, be fixed on the outlet pipe, it comprises, body, and it is a hollow cylindrical shell, the cylindrical shell bottom connects the connecting tube of establishing a band valve; It is fixed in outlet pipe, parallels setting with outlet pipe, and connecting tube is connected with outlet pipe; Floating drum, it is a cavity body structure, is arranged in the hollow cylindrical shell of body; Guide rod, an end connects floating drum, and the other end stretches out the body end cap.
Described floating drum bottom outer tube wall is provided with leads wing, and its effect is to eliminate hollow pontoon to have a down dip in the buoyancy of water effect.
Again, the utility model also is provided with axle sleeve saddle, a ring that supplies the guide rod guiding, fixes; Described axle sleeve saddle, ring are individually fixed in the hollow cylindrical shell of body top, and guide rod passes wherein; Nationality prevents that with cooperation hollow pontoon from tilting to use.
The other also parallel connection of described intake pipe is provided with one road water-adding pipe, which is provided with the moisturizing communication valve.
Also have in its floating drum bottom valve and short tube are housed, the first-class pipe fitting of slip-knot, be connected the setting position of waste pipe, the water level that makes the water seal displacement can moves freely hollow pontoon by connecting circulation at hollow cavity, and there by means of these simple members the water-sealing valve of original technology is had to be good handling.
