Abstract
The invention belongs to the fire extinguishing device field, and especially relates to a special opening device for a cold aerosol automatic fire extinguishing control system. The device comprises a pneumatic valve fixed at the port of a gas storage bottle and the gas storage bottle for opening the pneumatic valve, wherein the pneumatic valve is communicated with the gas storage bottle through a gas flow pipeline. The device has the advantages of simple structure, and realization of large opening moment, safety, reliability and long service life through the fire extinguishing implementation via utilizing high-pressure nitrogen in the gas storage bottle to open the gas storage bottle and drive a fire extinguishing agent in a powder tank.
Description
Technical field
The invention belongs to the extinguishing device field, relate in particular to a kind of special opening device for self-extinguishing control system adopting cold-air collosol.
Background technology
The industry such as oil field, refinery, enterprise are the emphasis fire prevention units in the fire-fighting program because of inflammable, the explosion hazard of its main production factors.How for physical condition and objective circumstances, adopt low-cost, high efficiency means of fire, eliminating fire in the early stage, the budding stage is the key subjects of every profession and trade, enterprise's fire safety.The production scene that is applied as every profession and trade, enterprise of self-extinguishing control system adopting cold-air collosol provides more reliable safe practice guarantee.This fire-fighting system maintenance cost is low, and the storage-stable phase is long, and fast cleanly fire extinguishing relatively is fit to China's national situation, and is significant to the fire-fighting fire extinguishing of the industries such as oil, natural gas, chemical industry, metallurgy and power communication.
Self-extinguishing control system adopting cold-air collosol mainly is comprised of shower nozzle, starter, air vent valve, pressure controller, opening device, gas bomb, powder tank, relief valve etc.Receive alarm signal, can automatically, also can be manual, make the startup magnetic valve action on gas bomb top, open gas bomb, the high pressure nitrogen in the gas bomb is got in the powder tank, and high pressure nitrogen sprays as the extinguishing chemical in the power drive powder tank, implements fire extinguishing.Opening device on the gas bomb starts magnetic valve and directly opens gas bomb for starting magnetic valve at present, because it is little to start the unlatching moment of magnetic valve, can cause opening failure.
Summary of the invention
Main purpose of the present invention is to overcome the deficiency of above-mentioned technology, and is provided for the special opening device of self-extinguishing control system adopting cold-air collosol, improves the unlatching moment of gas bomb, guarantees reliability and the security of self-extinguishing control system adopting cold-air collosol work.
The present invention for achieving the above object, by the following technical solutions: a kind of special opening device for self-extinguishing control system adopting cold-air collosol, comprise the pneumatic operated valve that is fixed on the gas storage bottle mouth position and the caisson that is used for starting pneumatic operated valve, described pneumatic operated valve is communicated with caisson by vent line.
Described caisson is made of small-sized gas tank and the bottle valve that is fixed on its tank mouth place, and described bottle valve is provided with valve control electromagnet; The gas outlet end of described bottle valve is communicated with described vent line.
Beneficial effect: the present invention is simple in structure, starts gas bomb by the high pressure nitrogen that is stored in the small-sized gas tank, by the extinguishing chemical in the driving of the high pressure nitrogen in the gas bomb powder tank, implements fire extinguishing again, and staring torque is large, and is safe and reliable, long service life.

Fig. 2 is application of the present invention;
Among the figure: 1, pneumatic operated valve; 2, vent line; 3, small-sized gas tank; 4, bottle valve; 5, valve control electromagnet; 6, shower nozzle; 7, starter; 8, gas bomb; 9, powder tank; 10, relief valve; 11, automatic fire alarm Fire extinguisher.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of special opening device for self-extinguishing control system adopting cold-air collosol comprises pneumatic operated valve 1, small-sized gas tank 3, bottle valve 4 and valve control electromagnet 5.Described bottle valve 4 is installed in the tank mouth place of small-sized gas tank 3, and valve control electromagnet 5 is used for controlling the unlatching situation of bottle valve 4; The outlet side of bottle valve 4 is communicated with the pneumatic operated valve 1 of the bottle mouth position that is installed in gas bomb 8 by vent line 2.In the described small-sized gas tank high pressure nitrogen is housed, opens when valve control electromagnet receives the 24V voltage signal, the high pressure nitrogen in the small-sized gas tank is exported in pneumatic operated valve by vent line, and pneumatic operated valve is opened gas bomb, and the high pressure nitrogen in the gas bomb enters in the powder tank like this.By indirectly controlling the pneumatic operated valve on the gas bomb, increased staring torque, improved reliability, the security of system works.
Operation principle: receive fire alarm signal, automatic fire alarm Fire extinguisher 11 output DC24V signals, the 24V signal is delivered to first starter 7, starter output 24V power supply, deliver to the valve control electromagnet 5 among the present invention, valve control electromagnet starts bottle valve 4, so that the pneumatic operated valve 1 that the high pressure nitrogen in the small-sized gas tank is opened on the gas bomb 8 through vent line 2, thereby so that the high pressure nitrogen in the gas bomb enters powder tank 9 by appendix, the pressure fast rise in the powder tank, after 1.4 MPas, starter 7 starts relief valve 10(or opens relief valve on the flour extraction pipe), extinguishing chemical is under the driving of high pressure nitrogen, through duff pipe, from shower nozzle 6 ejections, implement fire extinguishing.The present invention is simple in structure, starts gas bomb by the high pressure nitrogen that is stored in the small-sized gas tank, and gas bomb drives extinguishing chemical in the powder tank again, implements fire extinguishing, and staring torque is large, and is safe and reliable, can make 10 MPa high pressure nitrogens in the gas bomb, keeps at least 5 years terms of validity.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
