Abstract
PURPOSE:To make to control flow with good precision for various conditions of applicating liquid by using a flow control valve which has small rate of change in flow and still linear quality to valve lift. CONSTITUTION:Finished emulsion for application is detected flow rate by a flow detector in a feed pipe, and thereby a servomotor 6 is ordered to control a flow control valve 7, and flow control is performed so as to get a required flow rate. The flow control valve 7 is lifted and lowered through a valve stem 10, on the top of which a valve head 13, abut ting to a valve seat 11 and in conical or cylindrical shape, is provided. The valve head 13 is treated to conical or cylindrical shape in slender and so as to be small and still linear in rate of change of flow rate to lift of the valve stem.
