Description
Technical field
The utility model is related to a kind of coal gas drainer automatic gas leakage preventing devices, belong to metallurgy industry coal gas drainer
Equipment technical field.
Background technology
Various kinds of coal gas is largely used in smelter.Due to the variation of gas temperature and pressure, partial moisture is from coal
Separate out in gas becomes liquid water, accumulates in the duct.The presence of these condensed waters can hinder the proper flow of coal gas, increase
Add pipe loadings, pipeline break is caused when serious, accelerate the corrosion of pipeline, forms water attack and influence pipeline, valve and instrument member
The safe operation of part.Therefore, the condensed water in gas piping must be discharged in time, could ensure gas piping and affiliated facility
Safe operation.For this purpose, specially devising the coal gas drainer for gas piping.Gas condensed water is while being discharged into water trap
Also coal gas can be carry, therefore, water trap is as a possible gas leak mouth, in addition to having discharge condensed water function in time
While, it has to be possible to it is effectively prevent gas leak, there is good resistance to sparking energy.
Traditional wet bottom gas water trap, principle are to stretch into the drainpipe of gas piping lower part in water trap cylinder,
It is lived with the water seal of certain altitude, coal gas is made both not run not come out, the coal gas condensed water in pipeline can be automatically drained out again.Coal gas positive normal pressure
In the case of power, water trap can safe operation, but when gas pressure occur fluctuation, there is high pressure, cause water trap water level
The depletion of reduction or other reasons, water is not enough to seal coal gas, eventually causes coal gas and largely leak, and accident occurs.
Utility model content
The utility model aim is to provide a kind of coal gas drainer automatic gas leakage preventing device, can effectively prevent because of coal
Gas leak caused by drainage potential drop caused by gas pipe network pressure oscillation or other reasons is low solves to exist in background technology
The problem of.
The technical solution of the utility model is：
A kind of coal gas drainer automatic gas leakage preventing device, including tank body, conduit, guide rod, sealing plate, overflow cylinder, every
Plate and hollow floating ball with calibration bar are equipped with partition board, the left and right two that the inside division of tank body is connected to by partition board at lower end in tank body
The lower part of a chamber, tank body left chamber is equipped with overflow cylinder, and conduit is fixed on the upper end of tank body left chamber, and guide rod is located in conduit,
The lower end of guide rod be equipped with the matched sealing plate of overflow cylinder, the hollow floating ball with calibration bar is equipped in tank body right chamber, it is hollow
The calibration bar of floating ball is pierced by from the top of tank body.
The conduit is overlapped with the center line of overflow cylinder.
The center line of the conduit and overflow cylinder is arranged in parallel with partition board.
The both sides of the overflow cylinder are separately fixed on tank body and partition board.
The top of the tank body right chamber is equipped with blow down valve.
The utility model is used, in use, tank body is mounted on the overflow pipe of coal gas drainer, coal gas drainer is normal
When draining, the indoor sealing plate of tank body left chamber floats automatically, and condensed water flows into the right chamber of tank body by overflow cylinder, and through coal gas
The overflow pipe of water trap discharges；Drainage potential drop is low caused by gaspipe network pressure oscillation or other reasons, is not enough to seal
When chute blockage gas, the indoor sealing plate of tank body left chamber quick blocking overflow cylinder under the action of gas pressure is let out to cut off coal gas
Leakage approach.
The utility model has the beneficial effects that：It can effectively prevent caused by gaspipe network pressure oscillation or other reasons
Gas leak caused by drainage potential drop is low avoids the gas poisoning of gas leak initiation, catches fire, the generation of explosion accident.
It is simple in structure, it is easy to maintain, reduce the input of man power and material.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：It is tank body 1, conduit 2, guide rod 3, sealing plate 4, overflow cylinder 5, blow down valve 6, partition board 7, hollow floating with calibration bar
Ball 8, overflow pipe 9.
Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1, a kind of coal gas drainer automatic gas leakage preventing device, including tank body 1, conduit 2, guide rod 3, sealing
Plate 4, overflow cylinder 5, partition board 7 and the hollow floating ball 8 with calibration bar, are equipped with partition board 7 in tank body 1, and partition board 7 is by the inside points of tank body 1
The left and right two chambers of lower end connection are cut into, the lower part of 1 left chamber of tank body is equipped with overflow cylinder 5, and conduit 2 is fixed on 1 left chamber of tank body
The upper end of room, guide rod 3 are located in conduit 2, and the lower end of guide rod 3 is equipped with and 5 matched sealing plate 4 of overflow cylinder, 1 right chamber of tank body
Interior to be equipped with the hollow floating ball 8 with calibration bar, the calibration bar of hollow floating ball 8 is pierced by from the top of tank body 1.
In the present embodiment, tank body 1 is sealing, is mounted on the overflow pipe 9 of coal gas drainer, close to the room of water trap
Interior overflow cylinder 5 is welded with the inner wall sealing of partition board 7 and tank body 1, and the surface of overflow cylinder 5 is equipped with sealing plate 4, and sealing plate 4 is pine
