Float Valve Description of Downhole Drilling Tools

Float valve joint is one of the necessary tools for oil drilling. The float valve joint is connected to the upper part of the drill bit, and the float valve assembly in the joint is close to the connection thread of the drill bit, and can also be connected to the required place of the drill string. Its main functions are: to prevent mud from being brought into drill cuttings, sediment backflow, and block the water hole of the drill bit; when blowout and kick occur, the valve cover of the float valve assembly automatically closes the water hole, preventing the inside of the pipe string. The occurrence of blowout accidents.

● Model F Plunger Type Float Valve 1F2R-5F6R for Assembly Model F

The Model F Float Valve is a plunger-type float valve that provides a positive instantaneous shut off,providing constant fluid control while drilling,The model F is a reliable and the most economical selection under standard drilling operations.

● Model G Flapper Type Float Valve 2F3R-5F6R for Assembly Model G

The Model G is a flapper-type float valve that,when opened ,offers unrestricted bore through the float valve.The uniquely designed flapper closes rapidly to prevent cutting from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control.

● Model FA Plunger Type Float Valve 1F2R-5F6R for Assembly Model FA

The Model FA Float Valve has a special port running through the plunger of the float valve,This valve is used when monitoring the bit head for gas pressure and allowing differential pressure measuring when required.

● Model GA Flapper Type Float Valve 2F3R-5F6R for Assembly Model GA

The Model GA Float Valve is indistinguishable from the Model G with the exception of a tungsten-cabide insert in the flapper valve,The insert has a quarter-inch orifice through the center that allows for differential pressure monitoring .
