Audited Supplier API 7-1 drilling well Float Valve/ Float Valve Sub
1. Introduction:
This Float Valve is normally installed in a standard bore-back of the bit sub, to provide fluid flow control at the bottom of the drill stem. It also prevents backflow of cuttings from plugging the drill bit jets while making connections.
Float valve is one of necessary tool for oil drilling, it consists of float valve sub and float valve, The main function are to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt. When the well blowout or kick, the valve cover of float valve turn off the bore automatically, it will prevent well blowout accident. The working pressure of float valve is supposed to be 5000psi or 10000psi.
