Abstract
PURPOSE:To relax water hammering by providing a means of controlling electrification to an electromagnetic coil so as to separate a valve once or more from a valve seat before the valve is seated on the valve seat. CONSTITUTION:A control part 42 electrifies an electromagnetic coil 10 to separate an armature 20 from a magnetic pole 16, moving a valve 28 in the direction of a valve seat 30 by means of the energizing force of a leaf spring 26. And, immediately before the valve 28 is seated on the valve seat 30, the control part 42 electrifies the coil 10 for attracting the armature 20 toward the magnetic pole 16 for a defined time and, then, by electrifying the coil 10 again so as to separate the armature 20 from the magnetic pole 16, the valve 28 is seated on the valve seat 30 to close a valve. Thereby, water hammering can be relaxed.
