Abstract:
A solenoid valve for a high-pressure container of the present invention comprises: a body portion; a valve seat which is installed on the lower portion of the body portion and has a discharge port through which a raw material gas is discharged; a coil to which electric power is applied; a core installed on the inner surface of the body portion; a lower plunger; an upper plunger; an operating rod arranged in the upper plunger; a spring arranged between the core and the operating rod; and a ball member of a spherical shape which is in contact with the lower surface of the operating rod and is seated on a seating portion formed on the lower side of the upper plunger to open/close an orifice. Thus, the hermetic state can be maintained at low pressure, and leakage in the low-pressure state can be prevented.
