Top Drive IBOP safety valve

Top Drive IBOP safety valve

IBOP for top drive can be divided into Upper IBOP and Lower IBOP also called upper safety valve and lower safety valve; they are control valves which are used with the top drive system. Usually the two valves connected to the top drive drilling device. The IBOP adopts high reliable metal seal. So it can bear high pressure upward and downward. The working pressure can be achieved 10000 psi or 15000 psi. When well kick occurring, The upper IBOP can be closed by remote controlled, but the lower IBOP will be closed manually. Actuator for top drive is a subsidiary body which controls open and close of Upper IBOP. It works with other accessories of the rig, so that control opening and closing of Upper IBOP on any height of derrick driller console. Both the valve body cavity and accessories have special anti corrosive processing, so that prolong the working life.

Upper IBOP for top drive and lower IBOP for top drive are made up of body, lower valve seat, spring, ball valve, knob case, knob, upper valve seat, sealing ring and so on.

The sealing principle: the spring supports the lower valve seat to locate the ball, and that can make the ball contact with the ball seat’s sealing closely. When open, the water hole is unblocked, when close, the surface of the ball sealed against the water hole, the inner annular pressure acts on the ball to make the ball and the ball seat in high pressure and sealing situation.
