EMERGENCY VENTILATION SYSTEM OF SHIP USING FIRE MAIN LINE PRESSURE

摘要

PURPOSE: An emergency ventilation system for a ship using the pressure of a fire main pipe is provided to operate a water turbine motor and a ventilation fan without supplying power by opening a ventilation valve of a seawater supply line so that seawater can be supplied to the water turbine motor. CONSTITUTION: An emergency ventilation system for a ship using the pressure of a fire main pipe comprises a ventilation fan(20) and a water turbine motor(30). The water turbine motor is driven by the pressure of seawater supplied from the fire main pipe. A seawater supply line supplies the seawater to the water turbine motor, and comprises a fire hydrant(41), a ventilation valve(42), and a drain port(43). The ventilation valve controls the supply of seawater to the water turbine moror.
