Overview


The FT Drop-In Check Valve is an important tool to prevent return flow during a kick and are suitable for most drilling situations in which return flow through the drill string is a risk and normal operation requires the benefits of a full-bore sub. By preventing upward flow through the drill pipe, but allowing fluid to be pumped downward to circulate the well, the drop-in check valve provides the driller with the means to control the drill pipe pressures when required, significantly improving and simplifying well control. When blowout is going to be happened,the thread connections of the kelly is screw out immediately and the drop-in check valve will be put into the drill string and settled in the landing sub between the pipe and drill collar, at the same time, the slip will open automatically and be stuck in the zigzag flute of the landing sub. If the fluid tries to flow up, the rubber packer will expand and seal the annulus. Thus the blowout can be prevented.
