Installed in the central air-conditioning duct system works easily fusing temperature control gold using gravity acting and spring mechanism closes the valve. When a fire occurs, the fire invaded the duct, high temperature causes the fusible alloy melting on the valve, or to memory alloy deforms the valve automatically closes, for air duct and the fire district throughout occasions. Installed in ventilation and air conditioning systems to send, return air piping clean laminar flow operating engineering company, usually was turned on, when the gas pipeline fire when the temperature reached 70 ℃ purification, fusible film fuse, torsion force valve Auto Close hospital operating room decontamination equipment, in a certain period of time to meet the fire resistance stability and fire integrity requirements, from smoke fire retardant valves. When the valve is closed, the output off signal. ICU overall plan and the regional design A, pre-planning ICU mode (integrated or multi-unit mode), the number of beds (recommended multi-unit ICU beds each cell 8-12), visits visits system, the number of equipment needs (nursing station, storage room, number of facilities, number of employees, management and continuing education needs, etc.). B, ICU should be implemented to control access system. Through free access to the ICU situation allowed. Of supplies and medical staff visit channel must be separated from the channel. C, select the location as much as possible in light, well-ventilated place. D, there is an elevator, emergency room, operating room, radiology, laboratory as close as possible.
