摘要： Vent valve assembly for hot water boiler of type used in aircraft galleys permits trapped air in the boiler to escape during the initial fill. The valve includes a floating ball which rises as the boiler is filled so as to seat against an o-ring for sealing the boiler under pressure. A flow diverting plate positioned under the ball permits escaping air to rise rapidly around the ball without causing the ball to lift and be prematurely sealed against the o-ring. The plate also prevents the ball from blocking the air which must enter the boiler when it is drained.
