Abstract
PURPOSE: To evade the trouble due to the discharge of a little amount of water-drop in discharging air by forming integrally a relief valve with an automatic air vent valve and making in common the discharge ports of the air vent valve and the relief valve.
CONSTITUTION: Air is vent from a discharge port 16, passing through a penetration hole 18, and also a float 4 rises gradually. When the float 4 contacts with the penetration hole 18, discharge of air stops, and also the rise of water level stops. When water pressure rises, it pushes a valve 2 from underside, and separates the valve 2 from a valve seat 17 against the pushing force of a spring 7, and water flows out into a water-valve chamber 21 and is discharged from a discharge port 16, The discharge port of the automatic air vent valve and the discharge port of the relief valve are used in common, so when air is discharged, even if a little water-drop is discharged, none is called into question.
