Operation process of the quick shut-off valve
Thread Content
Could you please explain in detail the operating process of the turbine emergency shutdown valve? It would be great if there were animated diagrams as well. Thank you.
If the emergency shutdown device activates, or if the oil pressure drops, the spring force then becomes greater than the oil pressure behind the piston disc. As a result, the piston disc, along with the valve stem and valve disc, are rapidly pushed to the closed position by the spring force, while the quick-shut oil behind the piston disc is discharged through the return port. Of course, once you clear the oil passages when the quick-shut valve opens and closes, you will understand its working principle very well.

Hello, I have done some basic research on quick-close valves. To understand the process of operation, one must first comprehend the structure of the quick-close valve. There are some things that are hard to say; if you really want to learn, you can call me to talk, my number is 13683861991.
