In the above structure, since the outlet passage 10 is communicated from a part of the annular groove 6, a step 9 is formed at the connecting portion between the annular groove 6 and the outlet passage 10. There is a problem that the foreign matter 13 adheres and accumulates on the step portion 9 and the outlet passage 10 is narrowed, so that the discharge flow rate is reduced, and the outlet passage 10 is closed. That is, a steam trap is generally mounted on the outlet side of a steam-using device or at the end of a pipe, so that the temperature inside the trap is lower than that in a steam-using device or in a pipe, and is contained in the fluid. Iron ions and copper ions are easily deposited, and are deposited and deposited first in the step portion 9 (ie, convex portion) having the highest charge density in trap casing, and rust and scale are formed by using the initially deposited substances as nuclei. It grows and accumulates with the metal. In addition, the steam trap generally has an outlet connected to a drain pit via a drain pipe, so that when a backflow occurs, the outlet passage is closed due to the backflow of foreign matter in the drain pit. there were.
