Title:
DIAGNOSTIC DEVICE OF DRAIN TRAP AND DRAIN TRAP
Document Type and Number:
Japanese Patent JP2017211026
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To accurately diagnose whether gas is leaked from a drain trap or not.SOLUTION: A diagnostic device 40 includes a temperature/pressure sensor 41 for detecting a temperature and a pressure of fluid flowing through a discharge passage 15 of a drain trap 1, a heat conductive member 43 having one surface coming in contact with the fluid and the other surface facing the outside of the drain trap 1, a temperature sensor 42 for detecting a temperature of the other surface of the heat conductive member 43, and a diagnostic section 45 for diagnosing that gas is leaked from the drain trap 1 when the detected temperature of the temperature/pressure sensor 41 is equal to a corresponding saturation temperature of the detected pressure and the detected temperature of the temperature sensor 42 exceeds a prescribed determination threshold.SELECTED DRAWING: Figure 1
