Description
Technical field
The utility model relates to Pressure monitoring technical field, particularly relates to a kind of intelligent pressure/differential control system for structural fire protection.
Background technology
Along with developing rapidly of social economy's level, skyscraper form is in the sight of people more and more.
High-rise civilian office building becomes the important directions of domestic and international fire-fighting technology area research because of features such as its building interior function are complicated, fire spreading approach is many and evacuating personnel is difficult, and the smoke control system strengthening fire of high-rise building is of great practical significance to the casualties reduced in fire of high-rise building and property loss.
Forced draft is as the Smoke prevention mode of a kind of effective smoke proof staircase and cup, no matter the fire safety rules of home or overseas, have and consistent add pressure request, namely should make when fire, chamber pressure > corridor or room pressure before staircase pressure >.
Once breaking out of fire, the harm of flue gas stands in the breach, and therefore in fire attack process, whether smoke extraction can be implemented effectively, very large on fire extinguishing success or not impact.Smoke extraction can be divided into two large classes, one class is by hot pressing, the coefficient natural draught system of blast, and another kind of is the mechanical smoke extraction of leaning on mechanical force, in building, arrange air-supply machine room, start smoke exhaust fan when needed and carry out forced fume exhaust, to guarantee evacuation time and passage.
Build on ground, general nature smoke discharging effect is better, and during the breaking out of fire of hypogee, Action of Wind pressure is quite faint, relies on separately hot pressing function, and smoke discharging effect is poor, often will carry out mechanical smoke extraction.
In the actual scene of a fire, forced draft fume exhausting type effect is the most desirable.
So-called malleation, refers to the pressure differential of the fire resistant doorsets of smoke proof staircase, fire resistant doorsets both sides between cup and corridor.
And malleation degree can be divided into maximum permissible pressure value and minimum differntial pressure value.
So-called maximum permissible pressure value, refer to the maximum differential pressure value that the general manpower that all fire resistant doorsets descend fire resistant doorsets both sides to allow in off position can be pushed open, so-called minimum differntial pressure value, when referring to fire, personnel evacuate, fire resistant doorsets are once open, the pressure of staircase and enabling cup, by instantaneous decline, in order to prevent flue gas from invading, keep door opening place to have the due minimum pressure difference value of certain blowback wind speed.
According to " Code for fire protection design of buildings " GB50016-2006 9.3.3 article (strong article): in smoke proof staircase, the overbottom pressure value of mechanism contact type sensor fume-resisting system should be 40-50Pa; Cup, common antechamber should be 25-30Pa.
" Code for fire protection design of high rise buildings " GB50045-95(2005 version) 8.3.7 article: the total head of mechanism contact type sensor machine, except calculating least favorable not pipeline loss in head, still should have overbottom pressure.Its overbottom pressure value should meet the following requirements: 8.3.7.1 smoke proof staircase is 40Pa to 50Pa.
8.3.7.2 cup, share cup between room, Fire lift, close refuge story () be 25Pa to 30Pa.
The differential pressure pickup just used in the market, there are solid strain-type, inductance type, resistance-type etc., be difficult to follow the tracks of to larger pressure oscillation, the inertia of instrument own is comparatively large in addition, slow to pressure reacting condition, be difficult to react at short notice, thus produce the problem of pressure hysteresis, to number of floor levels and the more building of measuring point, be difficult to realize measuring simultaneously and rapidly, and can not effectively embody concrete pressure data in real time, just effectively can not play the fire prevention air blowing function of skyscraper.
