Abstract: A flowpath switch valve is configured for extended service life by spreading the region, of the sliding surfaces of a stator and a rotor, that is subject to wear over the entirety of the sliding surfaces. The stator has fixed stator flowpaths, and the rotor has rotor flowpaths. A flowpath switch valve, depending on the rotor rotation state, realizes connection patterns that include: a first connection pattern wherein a rotor flowpath 241 connects a fixed stator flowpath 31 and a fixed stator flowpath 32; a second connection pattern wherein the rotor flowpath 241 connects the fixed stator flowpath 31 and a fixed stator flowpath 36; a third connection pattern wherein a rotor flowpath 242 connects the fixed stator flowpath 31 and the fixed stator flowpath 32; and a fourth connection pattern wherein the rotor flowpath 242 connects the fixed stator flowpath 31 and the fixed stator flowpath 36.

Abstract: A liquid chromatograph has a long-life flow passage switching valve with reduced abrasion caused by sliding of flow passage end portions of a stator and flow passage end portions of a rotor seal. The flow passage switching valve includes: a stator; and a rotor seal connected with a rotor configured to rotate and slide on a circumference with respect to the stator. The stator has stator flow passages that open to the rotor seal. The rotor seal has a rotor seal flow passage for coupling two or more of the stator flow passages. A flow passage end portion that is positioned at a tip end in a sliding direction of the rotor seal flow passage is positioned in a direction opposite to the sliding direction of the stator flow passage end portion to be connected to the rotor seal flow passage, at least at the start of sliding.

Abstract: Provided are: a flow path switching valve that reduces the pressure load in a contact surface outer peripheral section of the flow path switching valve and inhibits friction between constituent components; and a liquid chromatographic device using the flow path switching valve. The flow path switching valve is provided with a stator having a plurality of through holes and a seal having conduction grooves for causing the through holes to conduct. The seal has a first portion present vertically beneath a region comprising at least a surface of contact with the stator, and a second portion having lower rigidity than the first portion, on the outside of the first portion. Due to this configuration, it is possible to reduce the pressure load when a flow path of a liquid is switched under high-pressure conditions, and inhibit the phenomenon of friction itself.
