Detailed Description

Drop-in type check valve is one of blowout preventers in drill string. When the sign of blowout emerges, the Kelly bar is instantly detached to throw the check valve into the water hole of the drill pipe, and is arranged on the position after the pump is opened, thereby preventing the blowout. This tool is provided with a positioning connector. The positioning connector is connected on the part of the drill string, which needs to be submersed into the shaft, convenient for the positioning of the check valve. The drop-in check valve is a heavy one-way valve with certain weight, and can automatically move to the positioning connector after being dropped in.
