Abstract
A valve with capability to self-anticipate failure has a body which is provided with at least one sensor assembly and a controller. The sensor assembly outputs a plurality of time-dependent sensing signals of a first operation parameter of the spindle of the valve or a plurality of time-dependent sensing signals of a second operation parameter of the valve door of the valve. The controller includes a storage unit, a computation unit, and an informing unit. The computation unit computes out a first trendline of the last plurality of time-dependent sensing signals of the first operation parameter stored in the storage unit or a second trendline of the last plurality of the time-dependent sensing signals of the second operation parameter stored in the storage unit. The computation unit also computes out a first accumulated-time threshold of the valve corresponding to a threshold of the first operation parameter over the first trendline or a second accumulated-time threshold of the valve corresponding to a threshold of the second operation parameter over the second trendline. The informing unit outputs the first or the second accumulated-time threshold to the remote of the valve.
