A cleaning device (4) is equipped with a cleaning mechanism (5) that removes foreign matter in a subject location in a flow passage, and a determination device (6) that determines an operation of the cleaning mechanism (5). The cleaning mechanism (5) has a deformation member (51) that is arranged at a position exposed to fluid flowing through the flow passage and is deformed by a change in temperature, and a cleaning member (52) that advances toward and retreats from the subject location in response to deformation of the deformation member (51), thereby removing foreign matter from the subject location. The determination device (6) has a magnet (61) that is displaced in conjunction with the cleaning member (52), a magnetic sensor (62) that detects the magnetic field of the magnet (61), and a determination unit (64) that determines the operation of the cleaning mechanism (5) on the basis of the detection result of the magnetic sensor (62).

If the period up to the point in time at which a malfunction is detected for the third time after the blockage-resolving operation is performed is equal to or less than a second threshold (S32, S33), a second malfunction prevention operation, which is the operation from among the blockage reoccurrence prevention operation and the air binding prevention operation that was not selected as the first malfunction prevention operation, is performed (S34).

Abstract

A shock absorber 1 is provided with a casing 10, and an absorption body 40 which moves when pushed by water flowing inside the casing 10. A first flow passage F1 is formed within the casing 10. A through-hole 46 which constitutes part of a second flow passage F2 and through which water flows is formed in the absorption body 40. When a backflow occurs, the absorption body 40 closes an inflow opening 23 to shut off the first flow passage F1 but allows water to flow through the second flow passage F2. In a normal flow state, the absorption body 40 is located closer to an outflow opening 33 than in the backflow state but maintains the outflow opening 33 open, thereby allowing water to flow through the first water flow passage F1 and the second water flow passage F2.

Abstract

The present invention includes a threshold value calculation unit that calculates a normal range that is a range of values that are taken when a steam trap is in a normal state, by using a predetermined calculation reference, based at least on state values with normal determination results, from among state values that have been stored in the storage unit during a predetermined period. A determination unit can perform predictive determination to determine whether the steam trap is in a normal state or a state that indicates an inclination toward a bad state and is highly likely to change to a bad state, by determining whether or not the state values are in the normal range, and the threshold value calculation unit performs accuracy determination to determine the accuracy of the predictive determination based on the results of the predictive determination regarding the state values stored in the storage unit, and adjusts the calculation reference based on the result of accuracy determination.
