Japanese Patent JP6711569
Kind Code:
B2
Abstract:
The present disclosure relates to a gas solenoid valve for controlling a flow rate of a gas. The gas solenoid valve includes a valve plug to be displaced in the main body between a closed position where the flow path is closed and an open position where the flow path is opened. The main body includes a retainer and a valve seat. The valve plug includes an armature surface and a valve part, the armature surface being displaced in accordance with the magnetic field, the valve part being formed integrally with the armature surface. The armature surface includes an opposed surface that is opposed to the retainer and contacts with the retainer when the valve plug is in the open position, so as to determine an amount of displacement of the armature surface. At least one of the opposed surface and a surface of the retainer is roughened.
