Abstract
The utility model discloses a buoy reversing stopping device for a gas pipeline. The buoy reversing stopping device comprises the gas pipeline; the gas pipeline is connected with a gas outlet pipe and a gas inlet pipe; a buoy reversing stopping device is arranged in the gas pipeline; the buoy reversing stopping device comprises clapboards and a buoy, wherein the buoy is buckled on the clapboards reversely; each buoy is provided with two rows of vent holes, each rows of vent holes comprises a plurality of vent holes; water is filled above the clapboard; the bottom end of the buoy extends beneath a water surface, so as to form water seals via the water surface; the gas outlet end of the gas inlet pipe extends to the buoy and extends out from the water surface. According to the buoy reversing stopping device, the water above the clapboards can seal the vent holes of the lower row of the buoy, the water level is about 200-300mm higher than the vent holes in the lower row of the buoy, and the upper row of vent holes in the buoy are floated out of the water surface when the buoy is lifted, so that the water can be completely added once. Gas supply is completed by ejecting the buoy under the action of gas in the gas inlet pipe and lifting the upper row of vent holes in the buoy above the water surface. The buoy falls off in case of no pressure, so that the upper row of vent holes can fall to the positions below the water surface freely to achieve the purpose of stopping reversed gas.
Description
Technical field
The utility model relates to a kind of gas pipeline floating drum reverse-blocking device.
Background technique
Behind the gas-purification of stalk system gas workshop, the gas reverse-blocking device is installed in the position before inflammable gas is outwards carried.The conventional water level method that adopts of existing gas reverse-blocking device, promptly more than the water surface, the height of water level of choke generally about 400～600mm, bleeds off, reduces air pump supply gas resistance to water during conveying gas from inlet hole to inlet hole at water level bottom, air outlet hole.Its shortcoming is: 1, will discharge water before each work, fill it up with water level again behind the end-of-job, bring a lot of inconvenience to operator; 2, Jia Shui discharges water and prolonged the operating time, and all will to bleed off the water yield be 0.16～0.22 cubic metre water at every turn, and is very uneconomical.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of existing technology; A kind of gas pipeline floating drum reverse-blocking device is provided; It utilizes the following row's exhaust port of water seal floating drum on the dividing plate, and height of water level exceeds floating drum under about row's exhaust port 200～300mm and arranges exhaust port on the floating drum when floating drum is risen and emerges, and once adds water to put in place; Supply gas is to rise on the water surface by the gas pressure jack-up floating drum in the suction tude, with row's exhaust port on the floating drum to accomplish; Floating drum falls during no pressure, and the row's of making exhaust port freely falls to dropping to the water surface with upper/lower positions, plays counterseal gas function.
For addressing the above problem, the utility model adopts following technological scheme:
The utility model provides a kind of gas pipeline floating drum reverse-blocking device, comprises gas pipeline, and said gas pipeline is connected with steam outlet pipe and suction tude; Be provided with a floating drum reverse-blocking device in the said gas pipeline; Said floating drum reverse-blocking device comprises a dividing plate and the floating drum of back-off on dividing plate; Floating drum is provided with two rows, every row has a plurality of exhaust ports; The dividing plate top is filled with water, and the floating drum bottom is stretched under the water surface and formed water seal by the water surface, and the outlet side of said suction tude is stretched in the floating drum and stretched out on the water surface.
On the said gas pipeline level displaying device is installed.
Said gas pipeline is provided with drain opening and water supplement port.
The utility model utilizes the water seal floating drum on the dividing plate to arrange exhaust port down; Height of water level exceed under the floating drum about row's exhaust port 200～300mm and when floating drum is risen on the floating drum row's exhaust port emerge; Once add water and put in place, supplying gas is to lean on gas pressure jack-up floating drum in the suction tude, row's exhaust port on the floating drum is risen on the water surface accomplish, floating drum whereabouts during no pressure; The row's of making exhaust port freely falls to dropping to the water surface with upper/lower positions, plays counterseal gas function.
Gas delivery pressure 3.2～3.5KPa, row's exhaust port gross area is greater than the flow of conveying gas on the floating drum, and it is light that the floating drum quality is wanted, and the tube area is not too small, and purpose is to drop to the gas delivery resistance minimum.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model provides a kind of gas pipeline floating drum reverse-blocking device, comprises gas pipeline 1, and said gas pipeline is connected with steam outlet pipe 2 and suction tude 3; Be provided with a floating drum reverse-blocking device in the said gas pipeline; Said floating drum reverse-blocking device comprises a dividing plate 4 and the floating drum 5 of back-off on dividing plate; Floating drum is provided with two rows, every row has a plurality of exhaust ports, the row's of being respectively exhaust port 6 and following row's exhaust port 7, and the dividing plate top is filled with water 8; The floating drum bottom is stretched under the water surface and is formed water seal by the water surface, and the outlet side of said suction tude is stretched in the floating drum and stretched out on the water surface.
Level displaying device 9 is installed on the said gas pipeline.
Said gas pipeline is provided with drain opening 10 and water supplement port 11.
The utility model utilizes the water seal floating drum on the dividing plate to arrange exhaust port down; Height of water level exceed under the floating drum about row's exhaust port 200～300mm and when floating drum is risen on the floating drum row's exhaust port emerge; Once add water and put in place, supplying gas is to lean on gas pressure jack-up floating drum in the suction tude, row's exhaust port on the floating drum is risen on the water surface accomplish, floating drum whereabouts during no pressure; The row's of making exhaust port freely falls to dropping to the water surface with upper/lower positions, plays counterseal gas function.
Gas delivery pressure 3.2～3.5KPa, row's exhaust port gross area is greater than the flow of conveying gas on the floating drum, and it is light that the floating drum quality is wanted, and the tube area is not too small, and purpose is to drop to the gas delivery resistance minimum.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
