Description
Technical field
The utility model relates to apparatus of air conditioning technical field, refers in particular to a kind of smoke proof staircase or cup pressurization is sent
Wind overbottom pressure value control device.
Background technique
When fire, smoke proof staircase and cup are the unique vertical channels of building interior evacuating personnel, it not only acts as peace
The place in temporary shelter place and enforcing remedies when the effect evacuated entirely and fire, it is a large amount of facts proved that, when fire
The personnel death overwhelming majority is caused by sootiness, therefore, when fire, it is necessary to carry out pressure air blowing to the place, be allowed to be formed clear
The zone of positive pressure of clean air plays the left and right of barrier flue gas intrusion.When the smoke proof staircase of pressure air blowing or the positive pressure value mistake of cup
Hour, it is not enough to prevent intrusion of the flue gas of fire bed under the synergy such as hot pressing, wind pressure, buoyancy, expansive force, when the region
When interior positive pressure value is excessive, causes personnel to be difficult to or egress door fire resistant doorsets can not be pushed open at all, influence evacuating personnel, consequence is tight
Weight.The pressurization air supply system in building is passed through using the forced draught blower that roofing or ground machine room lower is arranged at present
One vertical ventilating shaft, to by way of each cup air-supply（When pressurization air supply system serves cup）, the air outlet of cup is normal
Closed form air port, when fire, are unlocked fire bed and adjacent two layers air port；Or it blows to smoke proof staircase（When pressurization air supply system service
When smoke proof staircase）, the air outlet of staircase is from the air grille that hangs down.According to this way, after pressurization air supply system starting,
When smoke proof staircase or cup fire resistant doorsets are closed, smoke proof staircase or preceding indoor overbottom pressure are usually excessive, especially close blower
The cup at end causes fire resistant doorsets to be difficult to open, and influences the safe escape of personnel.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts and deficiency provide a kind of can effectively reduce and miss survey
Probability, and the smoke proof staircase of failure easy-to-search or vestibule pressurization overbottom pressure value control device, may be implemented to cup or
The overbottom pressure of person's staircase control effectively, and keeps overbottom pressure in safe range.
The utility model is achieved through the following technical solutions：
A kind of smoke proof staircase or vestibule pressurization overbottom pressure value control device, including controller, pressure detector, pressurization
Blower, bypasses air hose, special electric regulating valve and attached connection and power supply line, and the controller passes through connection and pressure difference
Detector is connected, and is connected by connection with special electric regulating valve, and booster fan is connected by air hose with pressure air blowing well,
The wind outlet section of booster fan is provided with bypass air hose, and bypassing on air hose has special electric regulating valve, and the controller is according to
The aperture that the data-signal of pressure detector controls the special electric regulating valve realizes that smoke proof staircase or cup overbottom pressure value are big
It is small in safe range.
Preferably, when necessary, the controller is also connected with fire protection control room.
Preferably, the controller uses PLC or single-chip microcontroller.
Preferably, the pressure detector is located at smoke proof staircase or each layer of cup.
Preferably, the pressure detector in the smoke proof staircase is located at the one third apart from the floor ladder bottom
Place.
The utility model provides the control device of a kind of smoke proof staircase or vestibule pressurization overbottom pressure value, smoke prevention staircase
Between pressurization air supply system or cup pressurization air supply system by the regulating and controlling effect of the device, may be implemented to pressure air blowing
The positive pressure value dynamic of smoke proof staircase or cup controls, and wants so that the overbottom pressure value of smoke proof staircase or cup meets safety
It asks, achievees the purpose that fire escape safe escape.
Compared with prior art, the utility model has the beneficial effects that：The utility model may be implemented effectively to manage Smoke prevention
The overbottom pressure value of staircase or cup in safe range, using with communication function detector, greatly reduces other type controls
The probability that device processed is accidentally surveyed, and failure is easy to search.Controller（Control host）According to the data information of detector, with patrolling
The stroke that program rationally manages special electric regulating valve is collected, avoids pressure oscillation larger.
Detailed description of the invention
