用于确定电子控制的和马达驱动的膜片阀的阀膜片的状态参量的方法以及膜片阀系统
摘要：
一种用于确定马达驱动的膜片阀(10)的阀膜片(20)的状态参量(Δ1)的方法，所述方法包括如下步骤：a)在第一时间范围中：使所述阀膜片(20)运动，使得所述膜片阀(10)从第一状态过渡到第二状态，在此b)检测与所述阀膜片(20)的运动过程相关联的参量的至少一个参考值；c)在第二时间范围中：使所述阀膜片(20)运动，使得所述膜片阀(10)从第一状态过渡到第二状态，在此d)检测与所述阀膜片(20)的运动过程相关联的参量的至少一个运行值；e)将所述至少一个参考值与所述至少一个运行值比较或与从其中所获得的参量的至少一个运行值比较；以及f)从比较的结果中确定状态参量。
摘要（英）：

The invention relates to a method for determining a state variable (DELTA 1) of a valve diaphragm (20) of a motor-driven diaphragm valve (10) , which comprises the following steps: a) in a first timerange: 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.
