Kelly valve (IBOP) can be divided into upper kelly valve and lower kelly valve. They are a kind of control valve used with the top drive system. Normally, two kelly valves are connected in series on the top. Drive the drilling device. The valve adopts a highly reliable metal-to-metal seal and can withstand high pressure from both upper and lower sides. Its working pressure is 5000Psi to 15000Psi. If a well surge is detected, the top drive can be remotely shut down by the top drive, and the top drive can be closed manually, which is an effective way to prevent blowout.
