Kitchen in, the oil smoke in gas flue blows back into kitchen in order to prevent, smoke exhaust ventilator outlet mouth of pipe and public gas flue
Between it is general be all provided with the device as fire-proof valve for flue, existing fire-proof valve for flue is generally comprised and is made of shell
Exhaust gases passes, the exhaust gases passes have opposite air inlet and air outlet, the outlet mouth of pipe of smoke exhaust ventilator are connected on air inlet, out
Air port is extend into public gas flue, and valve block able to turn on or off is provided at exhaust gases passes air outlet, and valve block is a piece of or two panels
It is hinged on exhaust gases passes by valve block shaft, air outlet side is provided with the high temperature that valve block can be made to forcibly close and closes device.When
When without using kitchen ventilator, valve block is covered since self gravity is in the closed position in outlet air oral area；When using kitchen ventilator, valve block
In an open position, valve block is far from air outlet.Due to the public public gas flue in a longitudinal direction of more users, once single household is sent out
It lights a fire calamity, a large amount of high-temperature harmful gas pours in longitudinal public gas flue, at this time if closed in fire-proof valve for flue not in time
Valve block, these a large amount of high-temperature harmful gas can be entered by the exhaust gases passes of fire-proof valve for flue be used the use of kitchen ventilator
In the man of family, to threaten the life security of resident.Existing fire-proof valve for flue is provided on the outer end face of outlet air end and is setting
Determine the high temperature that at temperature valve block can forcibly close to air inlet side and close device, when flue-gas temperature is in very in public gas flue
Under the high state of emergency, when flue-gas temperature reaches the warning temperature of setting in public gas flue, which, which closes device, makes to be in
The valve block of opening state is closed by force.But it is to use the strength of spring by valve that the high temperature on existing fire-proof valve for flue, which closes device all,
Piece is closed, and when continuous high temperature is to certain time in public gas flue, for spring because of high temperature failure, valve block loses the restrained force of spring,
It can be opened again, high-temperature harmful gas can pour in user family, to threaten the life security of resident.
