Be fixed with rotating shaft on the described blade, the end of this rotating shaft is fixedly connected with driving lever, and the two ends of this driving lever are connected to the traction link and the elasticity reset device of described electromagnetic traction device.
Described elasticity reset device comprises reset tension spring, and this reset tension spring one end is connected in described driving lever, and the other end is connected with tension, and this tension is fixed on the described valve body.
Junction with described blade rotor on the described valve body is provided with the copper sheathing that adapts to described blade rotor.
The air inlet of described valve body adopts decorating structure.
The air outlet of described valve body adopts decorating structure.
Technique effect of the present utility model is as follows:
Because the utility model automatic fire control relief valve, realize opening or the blade of valve body air port passage is connected with drive unit to rotating by the position, the position rotation that is blade is controlled by drive unit, this just can make the pressure relief opening on the guard plot exterior wall not be in normally open, thereby can help keeping guard plot exterior wall airtight performance at ordinary times, again can be in the extinguishing chemical dispose procedure according to the requirement of the gas extinguishing system guard plot inner overpressure of releasing automatically.
Because drive unit adopts the pressure reduction accessory drive, that is to say, directly with guard plot external and internal pressure difference as the unlatching parameter of automatic fire control relief valve drive unit with close parameter, thereby help realizing moving automatic open close accurately.
Because the pressure reduction accessory drive comprises the pressure tester of electromagnetic traction device and this electromagnetic traction device action of control, the traction link of described electromagnetic traction device is connected with described blade; Be fixed with rotating shaft on the described blade, the end of this rotating shaft is fixedly connected with driving lever, and the two ends of this driving lever are connected to the traction link and the elasticity reset device of described electromagnetic traction device; Described elasticity reset device comprises reset tension spring, and this reset tension spring one end is connected in described driving lever, and the other end is connected with tension, and this tension is fixed on the described valve body; This just helps effectively finishing following work: according to the structural requirement of gas extinguishing system guard plot, set the force value of relief valve action, pressure tester detects the pressure in the guard plot in real time; When fire took place, gas extinguishing system started, and the guard plot internal pressure raises, when pressure reached setting value, pressure tester sent actuating signal and gives the electromagnetic traction device, and the electromagnetic traction device moves rapidly, drive driving lever by traction link, driving lever drives blade by rotating shaft 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 for once more the electromagnetic traction device, and the traction link of electromagnetic traction device resets; Simultaneously, reset tension spring drives rotating shaft and blade action by driving lever, and blade is returned to closed condition from the enable possition rapidly, to guarantee the concentration of extinguishing chemical in the guard plot.
