Valve arrangement for e.g. distribution of liquids in analyzer that is utilized for determination of total organic carbon of drinking water, has multi-way valves resting against surface of disk, where surface is adjustable by movement

摘要

The arrangement (60) has multi-way valves resting against a support surface (65) of a ceramic disk (61). Three through holes (69.1-69.3) are formed in another ceramic disk (63) and connected together by a channel (67). The support surface of the former ceramic disk is adjustable in a valve position by a relative movement between the disks over the channel. The disks are moved between the valve position and another valve position relative to each other. The disks are rotatable relative to each other around a common rotational axis that extends vertical to the support surface. An independent claim is also included for an analyzer for automated determination of a measuring variable of a measuring liquid.
