Document Type and Number:
Japanese Patent JP7132648
Kind Code:
B2
Abstract:
The invention discloses an hinged valve. The hinged valve includes a valve body, a valve stem, a valve spool, an actuator and a sliding member. The valve body is a housing, which is formed with a valve stem hole for partially accommodating the valve stem. A passage having an inlet and an outlet is formed in the housing. The valve spool is connected to the valve body through a hinge, so that the valve spool is able to rotate around the rotation axis of the hinge. The actuator cooperates with the sliding member, so that the rotational movement of the valve stem is transmitted to the valve spool through the actuator via the sliding member and converted into a movement that drives the valve spool to rotate around the rotation axis of the hinge to open or close the valve. The valve spool is provided with a locking post, the bottom end of the valve stem is provided with a locking hook. A locking boss is provided on the locking post, and a locking-ledge is provided on the locking hook. When the valve is in the closed state, the valve spool is locked to the valve body by the locking hook and the locking post, and the locking-ledge on the locking hook and the locking boss on the locking post cooperate with each other. The valve of the application has a more reliable locking and a more reliable sealing.
