Fireproof door control integration system

Abstract

The invention relates to the pneumatic control technology, in particular to a fireproof door control integration system. The system comprises an air pump, wherein the air pump communicates with an airstorage tank through a pneumatic control valve; the pneumatic control valve further communicates with a shuttle valve II through an electromagnetic valve in sequence; the shuttle valve II communicates with a quick exhaust valve and a pneumatic control decompression valve respectively, the system further comprises a door opening air cylinder, the quick exhaust valve communicates with a door opening air inlet of the door opening air cylinder, the pneumatic control decompression valve communicates with a door closing air inlet of the door opening air cylinder, the air storage tank further communicates with the pneumatic control decompression valve through a pressure reducing valve, the system further comprises a check valve, the pneumatic control valve communicates with the decompression valve through the check valve, the system further comprises a shuttle valve I communicating with the air pump, the air storage tank and the pneumatic control valve respectively and further comprises a fire alarm device connected with the shuttle valves; the door opening air cylinder can push and pull a fireproof door with weight up to 50 kg to move back and forth; the operating speed of the fireproofdoor is 0.1-0.2 m / s and the fireproof can be adjusted manually; and the system can work normally at the environmental temperature ranging from subzero 20 DEG C to 60 DEG C.

Description

technical field [0001] The invention relates to pneumatic control technology, in particular to an integrated fire door control system. Background technique [0002] In the prior art, in the fire partition door or other flammable and explosive occasions, it is necessary to use a fully pneumatic control valve to control the expansion and contraction of the cylinder, and the expansion and contraction of the cylinder controls the switch of the door or other equipment. At present, various control valves are used to control In the expansion and contraction work of the control cylinder, each control valve is independent of each other. On the one hand, the connecting air path between the control valves is long, and the response time of the cylinder is long. Especially in the event of a fire, the fire door needs to be closed immediately after opening the fire door. In order to prevent the spread of fire and the diffusion of smoke, the control valves in the prior art cannot open or cl...

[0002] In the prior art, in the fire partition door or other flammable and explosive occasions, it is necessary to use a fully pneumatic control valve to control the expansion and contraction of the cylinder, and the expansion and contraction of the cylinder controls the switch of the door or other equipment. At present, various control valves are used to control In the expansion and contraction work of the control cylinder, each control valve is independent of each other. On the one hand, the connecting air path between the control valves is long, and the response time of the cylinder is long. Especially in the event of a fire, the fire door needs to be closed immediately after opening the fire door. In order to prevent the spread of fire and the diffusion of smoke, the control valves in the prior art cannot open or close the fire doors quickly, and the response is slow; on the other hand, the connecting air paths between the control valves are easily disconnected due to external influences , causing the cylinder to fail to work normally, and the reliability is not high
