摘要： A method for operating a diaphragm valve (10) comprises the step of reading out data, which characterize at least one property of a diaphragm (14) of the diaphragm valve (10), from at least one data memory (24) integrated into the diaphragm valve (10), by means of a reading device (36). The method further comprises the steps of: (a) transmitting the read-out data to a processing device (40) which is arranged remote from the reading device (36) and the diaphragm valve (10); and (b) synchronizing the transmitted data with data present in the processing device (40).

摘要： The invention relates to a method for diagnosing a diaphragm valve (10) comprising the following steps: a) providing at least one first quantity that characterizes a valve diaphragm (14), at least one second quantity that characterizes the diaphragm valve (10), and at least one third quantity that characterizes operation of the diaphragm valve (10) to a determination device (46); determining a quantity that characterizes a current state of the valve diaphragm (14), in particular a current wear, from the first, second, and third quantities by means of the determination device (46) by using at least one algorithm.

摘要： A method for determining a state variable (Δ
1 ) of a valve diaphragm (20) of a motor-driven diaphragm valve (10) comprises the following steps: a) in a first time range: moving the valve diaphragm (20) in such a way that the diaphragm valve (10) changes from a first state into a second state; in the process b) detecting at least one reference value of a variable which is associated with the movement process of the valve diaphragm (20); c) in a second time range: moving the valve diaphragm (20) in such the way that the diaphragm valve (10) changes from the first state into the second state; in the process d) detecting at least one operating value of the variable which is associated with the movement process of the valve diaphragm (20); e) comparing the at least one reference value with the at least one operating value or variables acquired therefrom; and f) determining the state variable from the result of the comparison.
