Abstract

The invention relates to devices aimed to overlap the column of the tubing strings (TS) during the well running and overhaul repair without its killing. Device to overlap the column tubing strings includes a case, locking element in form of the cup with a saddle, shut-off valve with elastic element, coupling, adapter with radial channels, at that the adapter has additional axial channel in the pressure chamber and by-pass channel with elastic element, shut-off valve and a seat, and the accuracy class of the coupling and stem is the same that the accuracy class of the parts of a well pump.
