Abstract
The utility model provides a water sealed gas isolating device which comprises a base and an outer barrel body fixed on the base, wherein a seal cover and a gas outlet pipe are arranged at the upper part of the outer barrel body, an interlayer is arranged in the outer barrel body, and a gas inlet pipe penetrates through the interlayer; an inner barrel body is further invertedly arranged on the interlayer, one end of the gas inlet pipe is located in the inner barrel body, and the other end of the gas inlet pipe extends out of the outer barrel body; and a plurality of vent holes are formed in a side edge of the inner barrel body. The water sealed gas isolating device is simple in structure and convenient to operate, automatic cut-off of gas backflow under accident conditions is achieved, and potential safety hazards are removed.
Description
Technical field
The utility model relates to gas safe protective equipment, is specifically related to a kind of water-sealed type gas isolating device.
Background technique
Fuel gas return-flow vaporizing station harmfulness is huge, to manufacturing enterprise, brings very large potential safety hazard.Therefore; when causing fuel gas return-flow, the shutdown of combustion gas wind conveyer must have reliable isolation mounting to realize blocking-up; existing fuel gas return-flow early warning is to realize by personal monitoring; after operator find fuel gas return-flow, realize fuel gas return-flow and block again by closing air valve, it is often because human negligence causes great industrial accident.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, the water-sealed type gas isolating device of security protection performance excellence.
For solving the problems of the technologies described above, a kind of water-sealed type gas isolating device of the utility model, comprises pedestal, exterior bowl, described exterior bowl is fixed on pedestal, described exterior bowl top is provided with sealing cover and steam outlet pipe, and described exterior bowl is built-in with interlayer, and described interlayer runs through and is provided with suction tude; On described interlayer, being also inverted has that inner drum, described suction tude one end are placed in inner drum, the suction tude the other end is extended down to outside exterior bowl outward; Described inner drum side is provided with some exhaust ports.
Before the utility model operation, be equipped with a certain amount of water on interlayer, make its liquid level a little less than the outlet of suction tude, the exhaust port of inner drum is immersed in liquid level below simultaneously.When pressure that combustion gas is imported and produced by suction tude is greater than after inner drum deadweight, inner drum is realized floating.Inner drum floating certain distance final vacuum hole exposes to liquid level, and combustion gas is derived and by steam outlet pipe, imported work area again and use by exhaust port.When meeting accident, to combustion gas wind conveyer, shut down, after combustion gas discharge pressure disappears, inner drum declines under Gravitative Loads; When being immersed in liquid level below fuel gas return-flow approach completely, thoroughly blocks exhaust port, fuel gas return-flow removing the hidden trouble, and the sealing cover that exterior bowl arranges can be for convenience detach so that operator overhaul, maintenance.
Further, described sealing cover and exterior bowl joint are provided with the sealability that pad can increase exterior bowl, and it has increased susceptibility, the reliability of retardance fuel gas return-flow.
Further, described inverted inner drum bottom is provided with counterweight regulating course, and operator can realize combustion gas derivation and the efficient retardance to backflow combustion gas smoothly by increase and decrease counterweight according to the size that imports gaseous-pressure.
The utility model is simple in structure, easy to operate, can realize the automatic blocking-up of fuel gas return-flow, stops potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A water-sealed type gas isolating device, comprises pedestal 8, exterior bowl 3, and described exterior bowl 3 is fixed on pedestal 8, and described exterior bowl 3 tops are provided with sealing cover 1 and steam outlet pipe 11, and described exterior bowl 3 is built-in with interlayer 12, and described interlayer 12 runs through and is provided with suction tude 6; On described interlayer 12, being also inverted has that inner drum 10, described suction tude 6 one end are placed in inner drum 10, suction tude 6 the other ends are extended down to outside exterior bowl 3 outward; Described inner drum 10 sides are provided with some exhaust ports 9.
Described sealing cover 1 is provided with pad 2 with exterior bowl 3 joints.
Described inverted inner drum 10 bottoms are provided with counterweight regulating course 4.
Embodiment
Before operation, according to gaseous-pressure size, on counterweight regulating course 4, place corresponding counterweight 7, make liquid level 5 not to exhaust port 9 tops.During the work of combustion gas wind conveyer, the combustion gas of its conveying produces certain pressure and promotes inner drum 10 floatings, and after exhaust port 9 exposes to liquid level 5, combustion gas is derived by exhaust port 9 and imported work area by steam outlet pipe 11 and uses.After combustion gas wind conveyer hang-up, to gaseous-pressure disappearance, inner drum 10 sinks under the Action of Gravity Field of own wt and counterweight 7, and when exhaust port 9 is submerged in behind liquid level 5 belows, it has blocked the approach of fuel gas return-flow automatically, and fuel gas return-flow hidden danger is removed thereupon.
The utility model is simple in structure, easy to operate, has realized the automatic blocking-up of fuel gas return-flow under fortuitous event, has removed safety in production hidden danger.
