Non-automatic grout float collar float shoe
the tongue plate springs back pressure control valve is closed by the controlling single-stream period of time, which can effectively avoid the formation of a cement plug cement reflux in the tube.
Description
main feature:
1, a reliable back-pressure sealing mechanism, tongue valve and seat soft metallic material. After compression can produce micro-deformable, help to improve the sealing effect, the back pressure seal the bigger the better.
2, the tongue plate springs back pressure control valve is closed by the controlling single-stream period of time, which can effectively avoid the formation of a cement plug cement reflux in the tube.
