over-center valve
Thread Content
I’d like to ask everyone: what is the exact Chinese meaning of this valve? Thank you
Overcenter valves are similar to counterbalance valves in that their purpose is to maintain a set pressure against a load in order to prevent it from falling freely. The main difference is that an overcenter valve uses a pilot signal, usually coming from the inlet of the actuator, to assist in opening the spool. This pilot assistance makes the overcenter valve more efficient, and it reduces the amount of horsepower required as well as the heat generated within the system. This is some information I was able to find
It’s a bit like a pilot-operated valve, using the pressure of the medium itself to assist with sealing as well as opening and closing.
I think it’s better to translate it as a balance valve. http://3dportal.cn/discuz/viewthread.php?tid=630629 http://www.cncad.net/thread-78840-1-1.html
“Over-center” implies being \"off-center,\" and I wonder if translating it as \"eccentric valve\" conflicts with its function :)
I also think it’s an eccentric valve, but it doesn’t quite match the description on the 2nd floor
Eccentric valve: victory:
Tripe Eccentric Butterfly Valve: Three-eccentric butterfly valve. Eccentricity generally applies to butterfly valves. So I think “over-center valve” doesn’t necessarily mean an eccentric valve. It is suggested that the poster post it in the dashboard section to see what experts have to say!
