<p>A device (10) for controlling an earthquake-vulnerable or other operation according to seismic activity, such as the flow of water from a reservoir or natural gas to users, includes a control unit (12) for controlling the operation when actuated by a predetermined triggering movement, an actuator unit (11) for producing the triggering movement when the actuator unit is subjected to a threshold level of seismic activity, and a coupling unit (13) for coupling the triggering movement from the actuator unit to the control unit. Mounting components are provided for mounting the coupling unit on the control unit and the actuator unit on the coupling unit so that a user can adjustably set the position of the actuator unit relative to the control unit in order to level the actuator unit in two different directions. One embodiment includes a first clamped flange (30) for mounting the coupling unit (13) on the control unit (12) so that a user can pivot the position of the coupling unit relative to the control unit about a first axis (21), and a second clamped flange (34) for mounting the actuator unit (11) so that a user can pivot the position of the actuator unit relative to the coupling unit about a second axis (22). Hydraulic or electrical control units may be used.</p> |
