摘要：
An orifice changeable pressure type flow rate control apparatus comprises a valve body of a control valve for a pressure type flow rate control apparatus installed between an inlet side fitting block provided with a coupling part of a fluid supply pipe and an outlet side fitting block provided with a coupling part of a fluid takeout pipe; a fluid inlet side of the valve body and the inlet side fitting block, and a fluid outlet side of the valve body and the outlet side fitting block are detachably and hermitically connected respectively so a flow passage for gases through the control valve is formed; and, a gasket type orifice for a pressure type flow rate control apparatus is removably inserted between a gasket type orifice insertion hole provided on the outlet side of the valve body and a gasket type orifice insertion hole of the outlet side fitting block.
