    • According to one embodiment, a flow channel opening and closing device includes a first rotating plate provided rotatably along a face which crosses two adjacent flow channels, having a first fluid passing hole which overlaps with each of the two flow channels midway during rotation, which fully opens the one flow channel and blocks the other flow channel at a region except the first fluid passing hole by making the first fluid passing hole overlap with the one flow channel, and a second rotating plate provided adjacent to the first rotating plate and rotatably along a face which crosses the two flow channels, having a second fluid passing hole which overlaps with each of the two flow channels midway during rotation, which rotates to a position where the second fluid passing hole overlaps at least partially with the one flow channel when the first rotating plate rotates to a position where the first fluid passing hole fully opens the one flow channel.
    • 根据一个实施例,一个流道开启和关闭装置包括第一旋转板,该第一旋转板沿着与两个相邻的流动通道相交的面可旋转地设置,具有第一流体通过孔,其在旋转期间中途与两个流动通道中的每一个重叠, 打开一个流路并通过使第一流体通过孔与一个流路重叠而在除了第一流体通过孔之外的区域处阻挡另一个流路,以及与第一旋转板相邻设置的第二旋转板, 横过两个流动通道的表面具有第二流体通过孔,该第二流体通过孔在旋转期间中途与两个流动通道中的每一个重叠,当第二流体通过孔第一流体通过孔与第一流体通道至少部分地与第一流动通道重叠时, 旋转板旋转到第一流体通过孔完全打开一个流动通道的位置。
