发明名称 Earthquake relief valve
摘要 This disclosure is directed to a vibration or shock-activated valve. A valve mounted for rotation in a gas line or the like is connected to an elongate handle by a valve stem. The valve is spring activated to rotate from an open to a closed position. The elongate handle engages and is restrained by a ball detent. The ball detent is normally urged into engagement with the elongate handle by a conical end of a pendulum member. When vibration or shock moves the pendulum, the ball detent releases the elongate handle permitting the spring loaded valve to rotate from the open to the closed position. A handle stop at 90 DEG stops the valve in the closed position.
