    • A flow control device for a gas chromatograph is provided. The flow control device includes first and second valves each having alpha and beta operating states and a plurality of ports. In each of the first and second valves, the ports are associated to have alpha pairs of the ports and beta pairs of the ports. In the alpha operating state of each of the first and second valves, the ports in each of the alpha pairs are connected and the ports in each of the beta pairs are disconnected. In the beta operating state of each of the first and second valves, the ports in each of the beta pairs are connected and the ports in each of the alpha pairs are disconnected. The first and second valves are formed by a cylindrical manifold plate disposed between cylindrical first and second port plates. A first diaphragm is disposed between the first port plate and the manifold plate and a second diaphragm is disposed between the second port plate and the manifold plate.
    • 提供了一种用于气相色谱仪的流量控制装置。 流量控制装置包括每个具有α和β操作状态的第一和第二阀以及多个端口。 在第一和第二阀中的每一个中,端口被连接成具有α对端口和β对端口。 在第一和第二阀中的每一个的α操作状态下,连接每个α对中的端口,并且每个β对中的端口被断开。 在第一和第二阀中的每一个的β操作状态下,每个β对中的端口被连接,并且每对α对中的端口被断开。 第一和第二阀由设置在圆柱形第一和第二端口板之间的圆柱形歧管板形成。 第一隔膜设置在第一端口板和歧管板之间,第二隔膜设置在第二端口板和歧管板之间。
