清掃装置及びそれを備える弁装置
Document Type and Number:
Japanese Patent JP7294650
Kind Code:
B2
Abstract:
To easily grasp an operation situation of a cleaning mechanism.SOLUTION: A cleaning device 4 includes: a cleaning mechanism 5 for removing a foreign substance in an object place in a flow passage; and a determination device 6 for determining the operation of the cleaning mechanism 5. The cleaning mechanism 5 includes: a deformation member 51 arranged at a position exposed to a fluid circulating in the flow passage, and changing by the temperature change; and a cleaning member 52 for advancing/retreating with respect to the object place by the deformation of the deformation member 51, and for removing the foreign substance in the object place. The determination device 6 includes: a magnet 61 which displaces being interlocked with the cleaning member 52; a magnetic sensor 62 for detecting a magnetic field by the magnet 61; a temperature sensor 63 for detecting the temperature of the fluid in the flow passage; and a determination part 64 for determining the operation of the cleaning mechanism 5 based on the detection result of the magnetic sensor 62 and the temperature sensor 63.SELECTED DRAWING: Figure 1
