Abstract
A motor providing safety actuation including a spring which, during the power outage, is designed to close a valve by moving a valve cone towards a valve opening. For installation or transportation of such valves with motors, it is desirable to lock the valve actuation rod. A device is described for securing a resilient locking element to the valve cone which is mounted on a valve actuating rod. In the desired installation position, the locking element is in a force-transmitting engagement with a guide mechanism of the actuating rod so as to lock the actuating rod in a position or, alternatively, engages in a formfitting manner with a recess of the guide mechanism of the actuating rod. To secure the actuating rod in position in a force-transmitting or formfitting manner, the motor is powered until the valve actuating rod is sufficiently retracted. Subsequently, a mechanical connection is established between the resilient locking element and the guide mechanism of the actuating rod. After the motor is installed, the actuating rod is released by further retracting the valve actuating rod.
