Abstract

PURPOSE:To make a valve have a flow regulating function in addition to a nonreturn function by making a valve seat so as to be shiftably attached in the valve stem direction by dint of fluid force and to be energized in the opposite direction to a valve plate. CONSTITUTION:In a valve box 3 with an inflow port 1 and an outflow port 2, there is provided with a passage P being opened or closed by a valve plate 4 and a valve seat 5 opposed to this valve plate, and opening or closing of this passage P is attained by movements of the valve plate 4 and the valve seat 5 either. When feed water pressure goes up and a flow rate increases, the valve seat 5 is pushed up against force of a valve seat spring 17 depressing the valve seat 5 so that an opening area of the passage P is reduced. According to this method, an increase in the flow rate by a rise in the feed water pressure and a decrease in the flow rate by a decrement in the opening area of the passage P both are negated so that even if the feed water pressure goes up, the flow rate to keeps its constant value in consequence.
