The seal fan pipeline of the gas baffle door that the utility model provides, comprise Fan pipeline, Fan pipeline is provided with trap and can stops circulation of air, and the highest water surface of trap is lower than air inlet and the air outlet of Fan pipeline, and trap is provided with water valve.
When needs are closed the seal fan pipeline, by water valve water filling in the trap, make the trap water and stop circulation of air, make the flue gas in the flue can't pass through the seal fan pipeline; When needs opening encapsulation Fan pipeline, emit water in the trap by water valve, make trap unimpeded, thereby make the air-flow of seal fan can pass through the seal fan pipeline.
By foregoing description as can be known, with respect to the above-mentioned background technology, the seal fan pipeline of the gas baffle door that the utility model provides, at Fan pipeline trap is set, trap is provided with water valve, and water valve can be controlled the turnover of water easily, thereby makes the trap can opening and closing; Glassware for drinking water has good sealing property; can stop the circulation of air, thereby flue gas can't be passed through, and water can protect trap to avoid corrosion; so the seal fan pipeline that the utility model provides can opening and closing, and can effectively stop passing through of flue gas when closing.
Description of drawings
The structural representation of the seal fan pipeline of a kind of gas baffle door that Fig. 1 provides for the utility model embodiment.
The specific embodiment
Core of the present utility model provides a kind of seal fan pipeline of gas baffle door, and the sealing Fan pipeline can opening and closing, and can effectively stop passing through of flue gas when closing.Another core of the present utility model provides a kind of gas baffle door that comprises above-mentioned seal fan pipeline.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, in a kind of specific embodiment, the seal fan pipeline of the gas baffle door that the utility model provides, comprise Fan pipeline 1, Fan pipeline 1 is provided with trap 13 and can stops circulation of air, the highest water surface of trap 13 is lower than air inlet 12 and the air outlet 11 of Fan pipeline 1, and trap 13 is provided with water valve.Above-mentioned trap 13 can be independent water seal part, and the water seal part is connected with Fan pipeline 1 then, and also directly the part of Fan pipeline 1 is set to trap 13.
When needs are closed the seal fan pipeline,, make trap 13 waters and stop circulation of air to trap 13 interior water fillings by water valve, make the flue gas in the flue can't pass through the seal fan pipeline; When needs opening encapsulation Fan pipeline, emit water in the trap 13 by water valve, make trap 13 unimpeded, thereby make the air-flow of seal fan can pass through the seal fan pipeline.
By foregoing description as can be known, with respect to the above-mentioned background technology, the seal fan pipeline of the gas baffle door that the utility model provides, at Fan pipeline 1 trap 13 is set, trap 13 is provided with water valve, water valve can be controlled the turnover of water easily, thereby makes the trap 13 can opening and closing; Glassware for drinking water has good sealing property; can stop the circulation of air, thereby flue gas can't be passed through, and water can protect trap 13 to avoid corrosion; so the seal fan pipeline that the utility model provides can opening and closing, and can effectively stop passing through of flue gas when closing.
In addition, water valve comprises water intaking valve 131 and draining valve 132, and draining valve 132 is positioned at the bottom of trap 13.Water intaking valve 131 and draining valve were arranged in 132 minutes, and more convenient control discharged water to adding of trap 13, and draining valve 132 is positioned at trap 13 bottoms, and it is more convenient that trap 13 is discharged water.
