In order to give the operation indication convenient, described venting indicator lamp and urgent start and stop button are installed in the left and right sides outside the guard plot respectively.
The beneficial effects of the utility model are: this system has adopted the control design of full intelligence, and the fire extinguishing meter is raw material with the air, is released to key link by separation, storage, pipe network laying, control.Can adopt combination to distribute flexibly according to actual condition, and applied range, can not produce secondary disaster, economic benefit is obvious.Simultaneously, select control valve that selector valve and signal ball valve are combined, realized the intellectuality control to gas release, and convenient to operation, safe and reliable.
Description of drawings
Fig. 1 is the connection layout in kind that a kind of intelligence described in the utility model is annotated the nitrogen fire extinguishing system;
Fig. 2 is the block diagram that a kind of intelligence described in the utility model is annotated the nitrogen fire extinguishing system;
Among the figure: 1-main control system, 2-intelligence nitrogen-making device, 3-manual ball valve, 4-pressure transmitter, 5-nitrogen storage tank, 6-gas pipeline, 7-decompressor, 8-alarm detector, 9-audible-visual annunciator, 10-signal feedback device, 11-select control valve, 12-electrical cable, 13-venting indicator lamp, 14-guard plot, 15-nozzle, the urgent start and stop button of 16-.
The specific embodiment
With reference to the accompanying drawings a kind of intelligence described in the utility model being annotated the nitrogen fire extinguishing system is described further:
As shown in Figure 1, 2, a kind of for intelligence notes nitrogen fire extinguishing system, comprise main control system 1, intelligent nitrogen-making device 2, nitrogen storage tank 5, electrical cable 12, gas pipeline 6 and guard plot 14, described main control system 1 connects intelligent nitrogen-making device 2, and intelligent nitrogen-making device 2 is connected with nitrogen storage tank 5 by gas pipeline 6, and the dotted line shown in the figure all is electrical cable 12; Solid line shown in the figure all is gas pipeline 6.Simultaneously, nitrogen storage tank 5 is connected to guard plot 14 by gas pipeline 6, and 14 tops, guard plot are provided with nozzle 15.Simultaneously, intelligent nitrogen-making device 2 is connected respectively to pressure transmitter 4, decompressor 7, manual ball valve 3, alarm detector 8, venting indicator lamp 13, urgent start and stop button 16, audible-visual annunciator 9, signal feedback device 10 and selects control valve 11 by electrical cable 12; And select control valve 11 to be arranged in parallel a manual ball valve 3 by gas pipeline 6.Simultaneously, alarm detector 8 is installed in the guard plot top two side positions, and at least two of the quantity of alarm detector 8, can be three or four, and this can be decided according to the size of guard plot 14.Described selection control valve 11 is in series with a decompressor 7 and a manual ball valve 3 with the end that manual ball valve 3 is set up in parallel respectively by gas pipeline 6, can monitor and guarantee nitrogen state when transmitting so in real time.Simultaneously, the position that keeps to the side directly over the nitrogen storage tank 5 is provided with a pressure transmitter 4, so also the atmospheric pressure state of monitoring observation in the nitrogen storage tank 5 in real time.Also for monitoring in real time outputs to nitrogen state in the guard plot 14, the other end of signal feedback device 10 is arranged on the gas pipeline 6 between nozzle 15 and the selection control valve 11.Venting indicator lamp 13 and urgent start and stop button 16 are installed in the 14 outer left and right sides, guard plot respectively, when abnormal conditions take place, can judge the present located state fast, also can remove to open urgent start and stop button 16 by artificial mode, can put out a fire to it too.
When automatic alarm system was in readiness, the control system of intelligent nitrogen-making device 2 began to monitor in real time manual ball valve 3, pressure transmitter 4, decompressor 7, alarm detector 8, venting indicator lamp 13, urgent start and stop button 16, audible-visual annunciator 9, signal feedback device 10 and selects control valve 11 openings.Simultaneously, gather the real-time numerical value of nitrogen storage tank 5 upward pressure transmitters 4, and compare with the setting alarm threshold value; When being lower than setting value, start intelligent nitrogen-making device 2 automatically to nitrogen storage tank 5 supply nitrogen.When pressure transmitter 4 return numerical value be higher than set the maximum pressure value after, stop air feed automatically.
When main control system 1 detects alarm detector 8 signals on the guard plot 14 (as smoke detector, heat detector, temperature sensing cable, oxygen concentration detector etc., be fire when routine requires combinde alarms and take place), start audible-visual annunciator 9.Simultaneously, the selection control valve 11 of the corresponding guard plot 14 of main control system 1 control, beginning is 14 release nitrogen to the guard plot.And signal feedback device 10 sends feedback signal to main control system 1.After the affirmation, light venting indicator lamp 13; Meanwhile, pressure transmitter 4 detected pressures on the nitrogen storage tank 5 change, and intelligence nitrogen-making device 2 starts when reaching setting threshold, carries out the nitrogen supply to nitrogen storage tank 5; After be finished the release time of nitrogen, close and select control valve 11, signal feedback device 10 sends feedback signal simultaneously, and the fire extinguishing action is finished.
If audible-visual annunciator 9 is failed Normal Alarm, when the people when observing guard plot 13 actual breaking out of fires, can manually press the urgent start and stop button 16 that is arranged on the guard plot outside, start and select control valve 11 to carry out to put out a fire to move.
Behind the signal, select control valve 10 normally to open if main control system 1 receives the report for police service, main control system 1 sends fault warning.At this moment, can adopt manually and to open, guarantee that nitrogen storage tank 5 exhausts finish the fire extinguishing action.
