PROBLEM TO BE SOLVED: To prevent being scalded by preventing fluid in a valve casing from blowing to the outside. SOLUTION: The valve casing is formed from a body 1 and a lid 2. An inlet 5, a valve chamber 4 and an outlet 7 are formed in the valve casing. A valve seat member 9 is mounted on a lower part of the valve chamber 4. A discharge passage 8 communicating the valve chamber 4 with the outlet 7 side is formed on the valve seat member 9. A float 11 as a valve member for opening/closing the discharge passage 8 by being separated from/seated on the valve seat member 9 is arranged in the valve chamber 4. A piston 15 as a pressure responsive member is stored in a pressure chamber 14 formed by a plug 13, displaceably in the axial direction of the discharge passage 8. An operation member 16 movable forward and backward in the discharge passage 8 is fixed to the piston 15. The inlet 5 is connected to an inlet pipe 21, and an inlet communicating path 18 branched from the inlet pipe 21 and communicated with a pressure chamber 14 is connected to the inlet pipe 21. An on-off valve 22 is arranged on the inlet communicating path 18. COPYRIGHT: (C)2008,JPO&INPIT
