次偏芯型バタフライバルブ。The valve body 3 is pivotally connected to the swinging lever 4 for opening/closing operation by a pin 5 so as to be rotatable about an axis parallel to the swinging axis of the valve body 3, and the valve body 3 is connected to the swinging lever 4 for opening/closing operation. Along with the movement,
A mechanism is provided for regulating the attitude of the valve body 3 with respect to the swing lever 4 so that the valve body 3 is moved almost parallel to the flow path direction near the valve seat 6 and rotated at a position away from the valve seat 6. In the eccentric butterfly valve, in which the posture regulating mechanism is configured, a locking portion 8 for locking a first locking pin 7 connected to the valve body 3 is provided in parallel with the valve body 3. The valve body 1 is provided with a locking effect only during movement, and the swing lever 4 is provided with an elongated pin engagement hole 9 centered around the swing axis X of the valve body 3 relative to the swing lever 4. A second locked pin 10 connected to the valve body 3 is engaged in the elongated hole 9 so as to move relative to the swing lever 4 when the valve body 3 moves in parallel. A secondary eccentric butterfly valve that is characterized by its vertical position.
