とを特徴とする可動オリフイス弁。 Two perforated plates perpendicular to the flow direction of the fluid are interposed in the conduit and are placed in close contact with each other, one of which is fixed and the remaining one is slidably movable with respect to the other. In a movable orifice valve that variably adjusts head loss depending on the communication range of the circular holes, the two perforated plates are provided with a large number of through holes with a common regularity, and each through hole is A movable orifice valve characterized in that each of the hole diameters is not smaller than the hole diameter of the adjacent through-holes closer to the outer periphery, and the hole diameter of the central through-hole is larger than the diameter of the through-hole at the outermost periphery.
