摘要
PURPOSE: A down-stepped differential pressure type flow control device valve is provided to maintain uniform differential pressure by trebling differential pressure and have an effect to control minute flow rate.;CONSTITUTION: A down-stepped differential pressure type flow control device valve is composed as follows. The shapes of holes arranged on the surface of each cylinder are different. In a section where an opening stoke is 20% or less, multiple small slots(13) of which curved length is the largest are matched with small circular holes(16) to maintain uniform differential pressure. In a section where the opening stroke is 60% or less, middle slots(12) and middle circular holes(15) are arranged. In a section where the opening stroke is 60% or more, large slots(11) and large circular holes(14) are arranged so that supply flow rate can be more than tripled.;COPYRIGHT KIPO 2013
