Automatic device controller in drilling fluid return sub horizontal

摘要

Automatic device controller in drilling fluid return sub horizontal, is expected to be used preferably, and in both hidroperfurau00e7u00e3o as injection of cement grout, the technique of excavation soil tunnels and similar known as "jet grout Ing ", for the purposes of control volume of the material unloading,That come out during these activities of perturau00e7u00e3o and injection, said device comprising essentially a rectilinear tubular body (2) made of a cylindrical segment (3), followed by a narrowing conical trunk (4), and which is applied around the common shaft (5) of a form Tion of hidroperfurau00e7u00e3o and pumping of cement laitance,With the definition of a ring chamber intermediate (6), gifted by turn of a derivation lateral exit (7), receiving the tubing (8) conductive material in discharge, but with intercalation of a valve (9) for controlling passage of manual, automatic or equivalent NTE.
