IPC: F16K24/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To discharge a large volume of air when the discharging volume is too large by piercing an auxiliary hole in a side wall of a valve casing, and fitting an opening/closing valve to the auxiliary hole in a system where a small air hole formed in a center part of a loose valve disk to open/close a large air hole formed in an upper part of the valve casing. SOLUTION: When water flows into a valve casing 1 from pipes for water/ sewage works through a communication hole 2, a large air hole 3 is closed by a loose valve disk 4, and a small air hole 5 is closed by a float valve disk 6. When the weight of the float valve disk 6 is larger than the force to push up the float valve disk 6, and the float valve disk 6 is detached from a valve seat 5a of the small air hole 5 to evacuate the air inside a valve casing 1. Because the volume of the air to be evacuated is excessive, the loose valve disk 4 is involved in the air flow during evacuation, and floated, and if the large air hole 3 is closed, a ball valve 12 is turned to open an auxiliary hole 9.
