The present invention is further arranged to：Drive section is additionally provided on the transmission shaft, the drive section is equipped with and institute
State the keyway that flat key matches.
Beneficial effect：It is an advantage of the invention that under normal circumstances by electric and pneumatic or driving driving crank rotation of surging
Rotary plate reaches valve and turns off or on, in the case where the unusual failure that happens suddenly does not need gas source, hydraulic power source and power supply,
The lockset that connect with main crank of auxiliary crank frame driven by driving device will be unlocked, by the counterweight of main crank frame by valve oneself
It is dynamic to close, solve original driving device cannot in the case where power-off or electric device are broken down by valve rapid-closing,
How valve must turned off or under fault condition in especially some engineerings, so as to avoid safety accident generation.
The invention will be further described below in conjunction with the accompanying drawings.
