|Title:||FLOW DIVIDING VALVE|
A main passage 11 has two large-diameter parts 11a, 11b and a small-diameter part 11c positioned between the large-diameter parts 11a, 11b. An inlet passage 12 communicates with the small-diameter part 11c, and outlet passages 13, 14 communicate with the large-diameter parts 11a, 11b. A valve body movement mechanism 3 is provided with: a first valve rod 22, in which a first valve body 21 for opening and closing the space between one of the large-diameter parts 11a and the small-diameter part 11c is fixed to one end; a second valve rod 24, in which a second valve body 23 for opening and closing the space between the other of the large-diameter parts 11b and the small-diameter part 11c is fixed to one end; a first bellows 28, of which one end is fixed to a first bellows flange 29 and the other end is fixed to the first valve body 21; a second bellows 32, of which one end is fixed to a second bellows flange 33 and the other end is fixed to the second valve body 23; a frame body 25, which is provided to the exterior of the main passage 11 and which connects the first valve rod 22 and the second valve rod 24; and an actuator 26, which moves the frame body 25 in the opening/closing direction of the first valve body 21 and the second valve body 23.
