Abstract

The present invention relates to the field of valve-related technology, specifically to a steam trap comprising a valve body with a float disposed at the top of the valve body; an opening/closing assembly 1 disposed below the float, the opening/closing assembly 1 being in a normally closed state and opened during drainage; and an opening/closing assembly 2 disposed on one side of the opening/closing assembly 1 being in a normally open state and closed during drainage. The present invention provides two flow paths, valve 1 and valve 2, to allow for separate flow of steam and water. Furthermore, the present invention utilizes a float bracket, a reed, and a ball valve cover to cleverly achieve independent opening and closing, thereby enhancing sealing performance. Compared to conventional steam traps that rely solely on a float as a switch, the present invention significantly improves both sealing and safety.
