Title:
FLUID DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/093329
Kind Code:
A1
Abstract:
Provided is an electromagnetic valve (1), which is a fluid device in which a valve seat (110) and a valve body (25) are provided partway along a flow path (11) through which a liquid flows, the fluid device closing when the valve body (25) presses on the valve seat (110), and opening when a gap is produced between the valve seat (110) and the valve body (25). The electromagnetic valve (1) is provided with a first electrode (141) that is electrically conductive with respect to liquid on the upstream side of the valve seat (110) and the valve body (25) in the flow path (11), and a second electrode (142) that is electrically conductive with respect to liquid on the downstream side thereof, the first and second electrodes (141, 142) serving as electrodes for measuring the degree of electrical conductivity between the liquid on the upstream side and the liquid on the downstream side. Leakage of the liquid can be easily detected using the first and second electrodes (141, 142).
