Detailed
The throw-type back pressure valve type HY is an internal blowout preventer. When blowout is going to happen, the Kelly rod should be removed immediately and the back pressure valve assembly should be put into the water hole and then pumped downward to the required place. Thus, the blowout can be prevented.
