Opening/closing apparatus for discharge line of fuel cell electric vehicle

An opening/closing apparatus comprising:

• a body part provided at an outlet end of a discharge line configured to discharge a target fluid to outside in a first direction, the body part having a discharge part configured to discharge the target fluid to the outside in a second direction intersecting the first direction;
• a guide part configured to surround a periphery of the discharge part and guide the target fluid, which has passed through the discharge part, in the first direction;
• and
• an opening/closing part configured to selectively open or close the discharge part based on discharge pressure of the target fluid,
• wherein the opening/closing part comprises:
• a shaft part configured to be selectively movable upward or downward relative to the body part in response to pressure of the target fluid;
• and
• a cap member connected to the shaft part and configured to be movable in response to the upward or downward movement of the shaft part from a first position at which the cap member closes the discharge part to a second position at which the cap member opens the discharge part,
• wherein the shaft part comprises:
• a shaft body accommodated in the body part so as to be movable upward or downward;
• and
• a shaft plate provided at an end of the shaft body so as to cover the discharge line and configured to be selectively movable upward or downward in response to discharge pressure of the target fluid, and
• wherein the cap member is moved downward to the first position by its own weight when the discharge pressure of the target fluid applied to the shaft plate is eliminated.
