PURPOSE: A multistage orifice is provided to easily control pressure as multiple orifice members are installed in multiple stages to facilitate the assembly and separation. CONSTITUTION: A multistage orifice(1) comprises a pressure reducing part(10), a first flange part(20), a second flange part(30), and a fixing part(40). Multiple orifice members(11) having pressure reducing holes(15) are continuously installed inside the pressure reducing part. The first flange part is installed in one side of the pressure reducing part. The second flange part is installed in the other side of the pressure reducing part. The fixing part connects the first and second flange parts to fix the pressure reducing part.
