PROBLEM TO BE SOLVED: To provide a float type steam trap which can furthermore improve the valve closing ability, in the float type steam traps which can make an apparatus compact, and can improve the water discharging ability, and can improve the valve closing ability, and can prevent occurrence of the water hammering. SOLUTION: A body 1 has a float chamber 1c, an inlet port 1d, and an outlet port 1e. A holder 3 has a passage 3a communicating with the outlet port 1e therein, and is fixed to the body 1 inside the float chamber 1c. A valve seat 5 is provided so as to communicate with the outlet port 1e. A float 4 has a floating ball 4a, and a lever 4b. The float 4 is provided in the float chamber 1c so as to vertically move. A valve body 6 is provided in the lever 4b. The lever 4b is fixed to the floating ball 4a at one end thereof, and is rotatably connected to the holder 3 at the other end thereof. The valve body 6 slides with respect to the valve seat 5 to open and close the valve seat 5 in cooperation with the vertical movement of the floating ball 4a. The valve seat 5 and the valve body 6 are made of materials having different wear resistance respectively. The cross section of the edge of the sealing surface of the valve seat has the shape making a right angle or an acute angle. COPYRIGHT: (C)2005,JPO&NCIPI
