Aircraft potable-water system

摘要

An aircraft potable-water system (10) comprising an automatic valve (60) associated with an overflow line (50) and an automatic switch (70) associated with the storage tank (30). The switch (70) vents the storage tank (30) when it is not full, and automatically converts to a tank-pressurizing condition when the storage tank (30) is full. This conversion of the switch (70) causes the valve (60) to move to an overflow-open position so that excess potable water can be drained through the drainmast (18).

1. An aircraft potable-water system comprising:
a storage tank that is full when it contains a set amount of potable water and not full when it contains less than this amount; a ground-fill line having an upstream end adapted for connection to an external potable-water source and a downstream end communicating with the storage tank; an overflow line having an upstream end communicating with the storage tank and/or the ground-fill line and a downstream end communicating with a drain; a valve movable between an overflow-open position whereat potable water is not blocked from draining through the drain and an overflow-closed position whereat potable water is blocked from draining through the drain; and wherein the valve automatically moves and/or remains in its overflow-open position when storage tank is full and automatically moves and/or remains in its overflow-closed position when the storage tank is not full, this automatic movement being caused without manual or electrical interaction with the valve; and wherein the drain is a drainmast.
