DEVICE FOR PRODUCING BYPASSES UNDER PRESSURE IN FLUID PIPING SYSTEMS

摘要

The invention relates to a device for producing bypasses under pressure in fluid piping systems. The inventive device comprises a horizontal T-shaped body having a radial conduit which can be connected to a connecting collar or scat of the pipe to be bypassed and a radial conduit with a mouth for extracting fluid from the bypass. The aforementioned device is essentially characterised in that it comprises an inverted cup-shaped cutter with an overdimensioned tooth crown and, on the rear part thereof, a stepped extension with two threaded areas. One of said threaded areas is attached to the upper neck of the radial conduit and is closed with a cover and gaskets. According to the invention, the device comprises an actuation means which can be positioned on the neck and which is equipped with a feed screw and a shaft which can be connected to the end threaded area of the cutter by means of a male connector and a nut. The aforementioned actuation means also comprises a lateral valve which connects the outside with the inside of the radial conduit and the bypassed pipe by means of a chamber inside said actuation means and which can be used to inject an inert gas, check the sealing and purge the bypassed pipe.
