In the case of kind, fire smoke can flow backward inlet pipe road, not have the effect for preventing fire smoke from flowing backward.
The working method of the utility model are as follows: booster fan 12 is set as common wind speed, and the moment is sent to each floor of building
Wind, when fire occurs for a certain layer in building, generates flue gas, fire-fighting system detects that fire, starting exhaust fan 22 are used for
Smoke evacuation in time increases 12 air-supply air quantity of booster fan, and air-supply check (non-return) valve 3 and air draft check (non-return) valve 4 are under the action of respective wind-force, angle
Degree is opened towards respective wind direction.
In fume-resisting system, when 12 failure of booster fan, booster fan 12 cannot be sent to air supply duct 11 again
Wind, check (non-return) valve 3 of blowing at this time restore state when static state, and non-return valve cover 33 covers in non-return valve support 31, even if fire cigarette
Air-flow channels to air outlet, under the action of blowing check (non-return) valve 3, fire smoke can also be stopped to enter the reverse irrigation of air supply duct 11；When adding
When 12 wind-force of pressure fan is smaller, at each air outlet, if the blast pressure of air outlet is greater than the flowing pressure of fire smoke,
Non-return valve cover 33 opens certain angle under the action of positive pressure, then air outlet still can be defeated to elevator cup and staircase
Fresh air is sent, guarantees safety zone；If the blast pressure of air outlet is less than the flowing pressure of fire smoke, non-return valve deck
Plate 33 swings to the non-return valve support 31 of air-supply check (non-return) valve 3 under the action of pressure difference, non-return under the flowing pressure of fire smoke
Valve cover 33 tightly covers on the ventilation opening of air-supply check (non-return) valve 3, and fire smoke reverse irrigation is stopped to feed in air piping 11.
In smoke evacuation system, exhaust fan 22 discharges fume to fire smoke, and fire smoke is sucked exhaust duct first
21, when air draft air quantity is sufficiently large, fire smoke follows air draft wind direction discharge building high-rise under the action of pressure difference；Work as air draft
When deficiency in draught, fire smoke may flee hither and thither in exhaust duct 21, when the fire smoke fled is fled to a certain floor
When, the non-return valve cover 33 of air draft check (non-return) valve 4 swings to the non-return of air draft check (non-return) valve 4 under the Action of Wind pressure for fleeing fire smoke
Valve support 31, under the flowing pressure of fire smoke, non-return valve cover 33 is tightly covered on the ventilation opening of air draft check (non-return) valve 4, resistance
Baffle alters fire smoke into other floors.
Non-return valve cover 33 is that 35 longitude and latitude weaving of basalt fibre silk forms, light weight, when pressure difference changes,
Pressure difference can be followed to carry out the automatic adjustment of angle；Cover board support 34 is iron frame, and intensity is big, is hardly damaged；High temperature resistant, energy
It is enough to work normally under high temperature fire smoke environment without damaging.
Other technologies are referring to the prior art.
The above is only preferred embodiments of the present invention, is not the limit to technical solutions of the utility model
It is fixed, it is noted that those skilled in the art can also make further under the premise of technical solutions of the utility model
Improvement and change, these improvement and change should all be covered within the protection scope of the present utility model.
