バルブおよびバルブを備える流体制御装置
Document Type and Number:
Japanese Patent JP6743994
Kind Code:
B2
Abstract:
A valve includes a first valve housing, a second valve housing, a diaphragm, a first fixing part, and a second fixing part. The diaphragm defines an upstream valve chamber together with the first valve housing. The diaphragm defines a downstream valve chamber together with the second valve housing. The diaphragm is movable between a first position in which the diaphragm blocks communication between the upstream valve chamber and the downstream valve chamber, and a second position in which the diaphragm allows communication between the upstream valve chamber and the downstream valve chamber. When in its second position, the diaphragm makes contact with the inlet of the second discharge channel or the wall surface of the downstream valve chamber to seal between the second discharge channel and the first discharge channel, and when in its first position, the diaphragm allows communication between the first discharge channel and the second discharge channel.
