Abstract
The present disclosure relates to a valve device including a valve base having a discharge flow path through which a target fluid is discharged, a plunger configured to be rectilinearly movable from a first position at which the plunger closes the discharge flow path to a second position at which the plunger opens the discharge flow path, a solenoid configured to provide driving power for moving the plunger, and an anti-freezing member connected to the plunger and configured to prevent freezing of the target fluid in the discharge flow path by moving in the discharge flow path in conjunction with a movement of the plunger, thereby obtaining an advantageous effect of preventing the discharge flow path through which the target fluid is discharged from being clogged, and of improving safety and reliability.
Claims11
A valve device comprising:
- a valve base having a discharge flow path configured to discharge a target fluid therethrough, wherein the target fluid includes discharge water and exhaust gas that are produced during operation of a fuel cell stack;
- a plunger configured to be rectilinearly movable from a first position at which the plunger closes the discharge flow path to a second position at which the plunger opens the discharge flow path;
- a solenoid configured to provide driving power for moving the plunger;
- an anti-freezing member connected to the plunger and configured to restrict freezing of the target fluid in the discharge flow path by moving in the discharge flow path based on a movement of the plunger;
- and
- a hydrophobic coating layer provided at an outer surface of the anti-freezing member,
- wherein a distal end of the anti-freezing member passes through the hydrophobic coating layer, and a distal end surface of the distal end is exposed to an outside of the hydrophobic coating layer and configured to be exposed to an outside of the valve base.
