Retrievable Drop-in Check Valve, Inside Blowout Preventer Valve, 35~70 MPa
Retrievable drop-in check valve is a drill string inside BOP valve. It has a landing sub and connected to the right position of drill string, then put into the well, to help the check valve assembly into place. Retrievable drop-in check valve is one kind of one way check valve to prevent backflow when well kick. It allows fluid down to return well. This valve can control pressure in the drilling process and improve the well control obviously. As long as drop in, it can be into place on the land sub automatically, easy operate, so that achieve the purpose of the blowout control. In addition, compared with other previous drop-in check valve, the disassembly of this check valve can save a lot of manpower and material resources.
