power case and selector work together to realize standard model and lock model

spring finger can prevent the tools acting early cased by fluid fluction

nitrogen power mechnism gets more power when the pressure increasing. After the pressure was discharged , the tools can be operated also.

oil chamber mechanism delays the nitrogen pressure and nitrogen discharge, it ensures the the reliabilty of the open and close of the well

the metering case can be selected by differnt delay time
