Under the normal power-up situation, structural requirement according to the gas extinguishing system guard plot, set the force value of pressure relief opening action, pressure tester 6 detects the pressure in the guard plot in real time, when fire takes place, gas extinguishing system starts, the guard plot internal pressure raises, and when pressure reached setting value, pressure tester 6 sent actuating signal by Control Component 7 and gives gear-box motor 16, gear-box motor 16 moves rapidly, drives blade 2 by electromagnetic clutch 17 and moves simultaneously; Blade 2 arrives the enable possition from closed condition rapidly, and the pressure in the guard plot discharges rapidly, realizes the purpose of building enclosure in the protection guard plot.When the guard plot internal pressure is reduced to preset value when following, pressure tester 6 sends signal, gear-box motor 16 counteragents for gear-box motor 16 by Control Component 7 once more; Drive blade 2 backward rotation simultaneously, blade 2 is returned to closed condition from the enable possition rapidly, to guarantee the extinguishing concentration of extinguishing chemical in the guard plot.
Under the condition of outage, dead electricity, power failure, owing to there is not power supply, electromagnetic clutch 17 outages are thrown off with gear-box motor 16.When fire takes place; gas extinguishing system starts; the guard plot internal pressure raises, when pressure reaches certain value, because blade 2 is eccentric; pressure in the guard plot produces turning torque on asymmetric blade 2; this moment overcomes the suction of permanent magnet 10, and permanent magnet 10 is thrown off with adjusting screw(rod), and blade 2 is opened; pressure in the guard plot discharges rapidly, realizes the purpose of building enclosure in the protection guard plot.When the guard plot internal pressure was reduced to certain value, blade was by deadweight and the action of the gravity of linkage, and then permanent magnet mechanism holds adjusting screw(rod), and blade is returned to closed condition from the enable possition, with the extinguishing concentration of extinguishing chemical in the assurance guard plot.
As Fig. 4-shown in Figure 6, embodiment two of the present utility model.Different with embodiment one is, the electric driver of present embodiment is an electromagnetic actuator device, comprises electromagnet 4, traction link 5 and crank 13, and electromagnet 4 flexibly connects with traction link 5, and traction link 5 links to each other with blade rotor 3 by crank 13; Permanent magnet mechanism also is arranged on the homonymy of electromagnetic actuator device simultaneously, stationary links 9 is connected with blade rotor 3 by crank connecting link 13, the other end of stationary links 9 connects permanent magnet 10, adjusting screw(rod) 11 is fixed on the valve body by screw bracket 12, and stationary links 9 is connected with adjusting screw(rod) 11 adhesives by permanent magnet 10.
Under the normal condition, structural requirement according to the gas extinguishing system guard plot, set the force value of pressure relief opening action, pressure tester 6 detects the pressure in the guard plot in real time, when fire takes place, gas extinguishing system starts, the guard plot internal pressure raises, and when pressure reached setting value, pressure tester 6 sent actuating signal by Control Component 7 and gives electromagnet 4, electromagnet 4 moves rapidly, and drives blade 2 actions by crank 13; Blade 2 arrives the enable possition from closed condition rapidly, and the pressure in the guard plot discharges rapidly, realizes the purpose of building enclosure in the protection guard plot.When the guard plot internal pressure is reduced to preset value when following, pressure tester 6 sends signal for electromagnet 4 by Control Component 7, and electromagnet 4 dead electricity reset; Blade is by deadweight and the action of the gravity of linkage, and then permanent magnet mechanism holds adjusting screw(rod), and blade is returned to closed condition from the enable possition, with the extinguishing concentration of extinguishing chemical in the assurance guard plot.
Under the condition of outage, dead electricity, power failure: owing to there is not power supply; electromagnet 4 outages; traction link 5 is in suspended state; when fire takes place; gas extinguishing system starts; the guard plot internal pressure raises; when pressure reaches certain value; because blade 2 is eccentric, the pressure in the guard plot produces turning torque on asymmetric blade 2, and this moment overcomes the suction of permanent magnet 10; permanent magnet 10 is thrown off with adjusting screw(rod) 11; blade 2 is opened, and the pressure in the guard plot discharges rapidly, realizes the purpose of building enclosure in the protection guard plot.When the guard plot internal pressure was reduced to certain value, blade was by deadweight and the action of the gravity of linkage, and then permanent magnet mechanism holds adjusting screw(rod), and blade is returned to closed condition from the enable possition, with the extinguishing concentration of extinguishing chemical in the assurance guard plot.
Operation principle of the present utility model is:
Under the normal power-up situation, structural requirement according to the gas extinguishing system guard plot, set the force value of pressure relief opening action, pressure tester detects the pressure in the guard plot in real time, when fire takes place, gas extinguishing system starts, the guard plot internal pressure raises, and when pressure reached setting value, pressure tester sent actuating signal by Control Component and gives electric driver, electric driver moves rapidly, drives blade and moves simultaneously; Blade arrives the enable possition from closed condition rapidly, and the pressure in the guard plot discharges rapidly, realizes the purpose of building enclosure in the protection guard plot.When the guard plot internal pressure is reduced to preset value when following, pressure tester sends signal by Control Component to electric driver once more, the electric driver counteragent; Drive the blade action simultaneously, blade is returned to closed condition from the enable possition rapidly, to guarantee the extinguishing concentration of extinguishing chemical in the guard plot.
Under the condition of outage, dead electricity, power failure: owing to there is not power supply, (or the electromagnet outage is thrown off with traction link) thrown off in the electromagnetic clutch outage with motor, and permanent magnetism adhesive mechanism has an effect.When fire takes place; gas extinguishing system starts; the guard plot internal pressure raises; when pressure reaches setting value; because blade is eccentric, the pressure in the guard plot produces turning torque on asymmetric blade, and the magnetic force that this moment overcomes permanent magnet mechanism is opened blade; pressure in the guard plot discharges rapidly, realizes the purpose of building enclosure in the protection guard plot.When the guard plot internal pressure was reduced to certain value, blade was by deadweight and the action of the gravity of linkage, and then permanent magnet mechanism holds adjusting screw(rod), and blade is returned to closed condition from the enable possition, with the extinguishing concentration of extinguishing chemical in the assurance guard plot.
The above only is a preferred implementation of the present utility model.Should be pointed out that for a person skilled in the art,, can also make many distortion and improvement according to the same principle of invention of the utility model, such as: transmission mechanism can be selected gear drive or jointed gear unit for use.Reducing gear can be selected gear reduction unit, planet wheel decelerator, belt reducing gear or worm type of reduction gearing etc. for use; But these all fall into protection domain of the present utility model.
