E, outrigger is sprayed water system II water supply riser 6 with provide construct/watering (fire cistern) of fire demand water is connected, power control system in Smoke Sensor 10 is electrically connected with control device.
The quantity of construction exterior rack Multi-functional spray system of the present invention is arranged according to building shape, area, fire-protection rating, adopts successively setting or interlayer arrange or are arranged at layer and layer interlude, as shown in Figure 7.
Non-work layer fire-fighting spraying is every≤10m within the scope of setting spray water system together; Work layer needs every layer to arrange one maintenance (cooling) water-spray system; If during floor height > 4.0m, need on outrigger, add one maintenance spray system.
The selecting of the water pump in construction exterior rack Multi-functional spray system water supply pond of the present invention, being calculated as follows of the related data such as flow and fire cistern volume:
1. lift (the water supply elevation that water pump can reach): the highest sprinkler height of H=+minimum hydraulic demand+loss of flood peak; In the embodiment of the present invention, minimum hydraulic demand is 10m, and the loss of flood peak is 25m;
2. flow: Q=30L/S;
3. fire cistern calculates: the minimum dischargeable capacity Vm3 of fire cistern, that is: outrigger sprays 1 hour spray-water amount=3600 × flow Q.
The present invention is applicable to the setting of the construction exterior rack Multi-functional spray system of non-work layer fire-fighting and fire-fighting electrical equipment interlock principle is as follows:
Outrigger fire-fighting electrical equipment linked system is by cigarette sense autocontrol valve door assembly 72, droop enclosed spray nozzle 22, and Smoke Sensor 10 forms, and described cigarette sense autocontrol valve door assembly 72 comprises pressure reducing orifice 721, rocking bar signal valve 722, water flow indicator 723; The setting principle of pressure reducing orifice is: the horizontal mains pressure of general spray is not more than 0.4MPa, when spraying horizontal mains pressure and being greater than 0.4MPa, must arrange pressure reducing orifice.
1, area of fire protection divides: job site is vertical≤10m within the scope of floor be an area of fire protection, each area of fire protection should arrange the construction exterior rack Multi-functional spray system that more than a group is applicable to non-work layer fire-fighting; Each area of fire protection arranges a module cage, and module is arranged in metal module case, and each module controls the rocking bar signal valve 722 of a cigarette sense autocontrol valve door assembly 72 and corresponding one group of Smoke Sensor 10.
2, circuit connection controls with signal: module work voltage is 24V, Circuits System is connected with CCC Circuits System, module receives the signal of Smoke Sensor 10 by radio transmission apparatus, and controls the rocking bar signal valve 722 of cigarette sense autocontrol valve door assembly 72; Rocking bar signal valve 722 is by module controlled in wireless, and without the need to connecting power supply, Smoke Sensor 10 is connected, with module generation controlled in wireless with CCC electrical system; Central control system is arranged in job site remote monitoring Acceptance Test System.
3, linking fire operation principle: outrigger spraying system of fire fighting adopts preact system principle, in normal state, does not have water in distributing pipe line; When fire occurs, Smoke Sensor 10 senses that smog changes, and is reached by fire signal in the module of corresponding fire compartment, and module triggers the rocking bar signal valve 722 of cigarette sense autocontrol valve door assembly 72, opens rocking bar signal valve 722 and supply-water pump; After the rocking bar signal valve 722 of autocontrol valve door assembly 72 is opened automatically, preact system is converted into wet type warning system; When fire temperature continues to raise, the blocking device thawing of sagging type enclosed spray nozzle 22 comes off, sagging type enclosed spray nozzle 22 automatic sprinkling fire-extinguishing.
