PROBLEM TO BE SOLVED: To prevent the generation of the influence of abnormal pressure to each mechanism and part inside a trap by effectively reducing the abnormal pressure generated in a primary side of the piping. SOLUTION: A plurality of pressure reducing walls are arranged between the primary side piping and the inside of a trap main body, and the abnormal pressure generated in the primary side of the piping colloids with the plurality of pressure reducing walls in order, and the pressure is reduced through several steps. Thereafter, the fluid is made to flow into the trap main body to prevent the generation of a bad influence due to the abnormal pressure to each mechanism and parts inside the trap main body. |
