Abstract
PURPOSE: To close a valve securely by a method wherein a main valve is provided with a valve disk, a float being used for a pilot valve, a starting end of a flowout passage being opened in the center at one end of a valve chamber, and a terminal end of a flow-in passage being communicated to the periphery.
CONSTITUTION: A rise of a water level in a tank makes a float 20 float up and a sealing surface 21 attaches to a pilot valve seat 16, causing a pilot valve hole 13 be blocked. Thereupon, a pressure within a space below a valve disk 17 of a valve chest 5 rises approaching the pressure at an inlet port side 11. On the other hand, pressure between the valve disk 17 and an annular valve seat 6 falls according to a flow, the valve disk 17 is attracted to the side of an outflow passage 7, and a sealing surface 18 is attached to the annular valve seat 6 to block the outflow passage 7. At this time, the sealing surface 18 of the valve disk 17 is flat and because the valve seat surface of an outer valve seat 9 is formed on the same flat as the valve seat 6, the sealing surface 18 is simultaneously attached to the outer valve seat 9 as well.
