Abstract

PURPOSE: To enhance the anti-explosion safety of an actuator for operating a diaphragm valve, by placing all electric lines in compressed air supply pipings and a pressure container connected thereto, to isolate the electric lines from the external air.
CONSTITUTION: When the exciting coil 2 of a force motor 1 is energized, a lever 3 is moved to regulate the quantity of discharged air from a nozzle 5 by a flapper 4 mounted on the lever 3. As a result, compressed air B to be supplied to a pilot valve 6 is regulated. The regulated operating pressure C of the compressed air B is applied to the diaphragm 8 of a diaphragm valve 7 to open or close a valve 10. In such an actuator, the exciting coil 2 is energized by electric power supplied through a power line 15, a drive circuit 16 and another power line 17. The power line 15 is housed in a pipe 18 for supplying the compressed air B. The drive circuit 16 is housed in a pressure container 19 connected to the pipe 18. The power line 17 is housed in a pipe 20.
