Definitions
- the present invention relates to a flow path switching valve used in an analyzer such as a liquid chromatograph, and in particular, a stator having a plurality of ports for connecting flow paths, a surface closely contacting the stator, and between the stator ports on the surface.
- the present invention relates to a rotary type switching valve that includes a rotor having a switching groove for connecting the two ports, and switches the connection between the ports by rotating the rotor.
- the flow path switching valve used under such high pressure conditions has a stator having a plurality of ports for connecting the flow paths and a surface closely contacting the stator, and the surface is electrically connected between the two ports of the stator.
- a rotary switching valve provided with a rotor having a switching groove for the purpose (see Patent Document 1). The rotary switching valve rotates the rotor while bringing the planes of the stator and the rotor into close contact with each other, thereby switching the port to be conducted and switching the flow path to be connected.
- FIG. 1 An example of the structure of the rotary switching valve is shown in FIG.
- a cylindrical base 42 constituting the lower part of the housing and a stator 40 constituting the upper part of the housing are fixed by a plurality of screws 44.
- a plurality of ports 46 for connecting flow paths are provided on the upper surface of the stator 40.
- Each port 46 communicates with a lower surface 41 of the stator 40 which is an upper plane in the housing.
- the rotor 10 is accommodated in the base 42.

Between the outer peripheral surface of the rotor holding portion 8 and the inner peripheral surface of the base 42, a bearing 22 that suppresses rotation blur of the rotor holding portion 8 is inserted. A spring 18 is inserted between the rotor holding portion 8 and the bearing 20 in a compressed state. The rotor holding portion 8 is urged toward the stator 40 by the elastic force of the spring 18, whereby the rotor 10 is pressed against the lower surface of the stator 40. Thereby, the liquid tightness between the rotor 10 and the stator 40 is improved, and the liquid leakage from the switching groove 14 of the rotor 10 is prevented.

As a result, the flatness of the contact plane of the rotor with the stator is impaired, the torque for rotating the rotor increases, liquid leakage from the rotor switching groove occurs, and liquid remains in the worn part of the rotor. As a result, problems such as cross contamination occur. In addition, when the rotor wears, rotor shavings are generated, and the shavings flow with the liquid flowing through the switching groove and are introduced into the analytical column connected downstream of the switching valve, causing deterioration of the analytical column.
