To achieve these goals, the invention provides a kind of seal fan pipeline of gas baffle door, comprise Fan pipeline, described Fan pipeline is provided with the trap that can stop air circulation, the highest water surface of described trap, lower than the air inlet of described Fan pipeline and air outlet, described trap is provided with water valve.
Preferably, described water valve comprises water intaking valve and draining valve, and described draining valve is positioned at the bottom of described trap.
Preferably, described water intaking valve is positioned at the top of described trap.
Preferably, described trap is provided with overfall, the extreme lower position of the water surface when extreme lower position of described overfall circulates higher than described trap blocks air, the extreme higher position of described overfall is lower than described air inlet and described air outlet.
Preferably, described overfall is positioned at the side near seal fan on trap.
Preferably, it is characterized in that, the inwall of described trap is provided with protection rubber.
Present invention also offers a kind of gas baffle door, comprise baffle door, seal fan and connect the seal fan pipeline of described baffle door and described seal fan, described seal fan pipeline is the seal fan pipeline described in above-mentioned any one.
The seal fan pipeline of gas baffle door provided by the invention, comprises Fan pipeline, Fan pipeline is provided with trap and can stops air circulation, and the highest water surface of trap, lower than the air inlet of Fan pipeline and air outlet, trap is provided with water valve.
When seal fan pipeline closed by needs, by water valve to water filling in trap, make trap water and stop air circulation, making the flue gas in flue cannot by seal fan pipeline; When needs opening encapsulation Fan pipeline, released the water in trap by water valve, make trap unimpeded, thus make the air-flow of seal fan can by seal fan pipeline.
Known by foregoing description, relative to above-mentioned background technology, the seal fan pipeline of gas baffle door provided by the invention, Fan pipeline arranges trap, trap is provided with water valve, and water valve can control the turnover of water easily, thus trap can be opened and closed; Glassware for drinking water has good sealing; can stop the circulation of air, thus flue gas cannot be passed through, and water can protect trap from corrosion; so seal fan pipeline provided by the invention can open and close, and can effectively stop passing through of flue gas when closing.
Accompanying drawing explanation
The structural representation of the seal fan pipeline of a kind of gas baffle door that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
Core of the present invention is to provide a kind of seal fan pipeline of gas baffle door, and sealing Fan pipeline can open and close, and can effectively stop passing through of flue gas when closing.Another core of the present invention is to provide a kind of gas baffle door comprising above-mentioned seal fan pipeline.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, in a kind of detailed description of the invention, the seal fan pipeline of gas baffle door provided by the invention, comprise Fan pipeline 1, Fan pipeline 1 be provided with trap 13 and can air circulation be stoped, the highest water surface of trap 13, lower than the air inlet 12 of Fan pipeline 1 and air outlet 11, trap 13 is provided with water valve.Above-mentioned trap 13 can be independent water seal part, and then water seal part is connected with Fan pipeline 1, also directly a part for Fan pipeline 1 can be set to trap 13.
When seal fan pipeline closed by needs, by water valve to water filling in trap 13, make trap 13 water and stop air circulation, making the flue gas in flue cannot by seal fan pipeline; When needs opening encapsulation Fan pipeline, released the water in trap 13 by water valve, make trap 13 unimpeded, thus make the air-flow of seal fan can by seal fan pipeline.
Known by foregoing description, relative to above-mentioned background technology, the seal fan pipeline of gas baffle door provided by the invention, Fan pipeline 1 arranges trap 13, trap 13 is provided with water valve, and water valve can control the turnover of water easily, thus trap 13 can be opened and closed; Glassware for drinking water has good sealing; can stop the circulation of air, thus flue gas cannot be passed through, and water can protect trap 13 from corrosion; so seal fan pipeline provided by the invention can open and close, 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 132 are provided separately, more convenient control discharges water to adding of trap 13, and draining valve 132 is positioned at trap 13 bottom, trap 13 is discharged water more convenient.
In addition, described water intaking valve 131 is positioned at the top of described trap 13.Water intaking valve 131 is positioned at trap 13 top, is convenient to add water to trap 13.
Further, trap 13 is provided with overfall 133, the extreme lower position of the water surface when extreme lower position of overfall 133 circulates higher than trap 13 blocks air, the extreme higher position of overfall 133 is lower than the air inlet 12 of Fan pipeline 1 and air outlet 11.The effect of overfall 133 is to facilitate staff to judge, and whether trap 13 completes water seal.Particularly, carrying out in water seal process, when discharging the water being used for water seal in overfall 133, staff judges that water seal completes, then stop adding water.
Closer, overfall 133 is positioned at the side near seal fan on trap 13.In order to prevent the flue gas in flue from revealing from overfall 133, overfall 133 is arranged at the side near seal fan on trap 13, when trap 13 stops that flue gas passes through, overfall 133 place does not have smoke spillage.
In order to prevent trap 13 by flue gas corrosion, the inwall of trap 13 is provided with protection rubber.Be arranged at the protection rubber of trap 13 inwall, can prevent from infiltrating through flue gas in water to the corrosion of trap 13.
The aerator that the embodiment of the present invention provides comprises gas baffle door, and comprise baffle door, seal fan and connect the above-mentioned seal fan pipeline of baffle door and seal fan, the structure of other parts with reference to prior art, can repeat no more herein.
