Device for application to shutters in use with leakage from the packing gland, whose extension can be adjusted in height so as to insert into the bolt of the shutter itself regardless of its diameter and its length

摘要

Technological sector: mechanics; Sector: shutters with fluid conduits. Technical problem: It is known that any shutter with packing gland seal over the course of time has a leakage from it, which leakage is found between packing gland and control shaft for opening/closing of the shutter itself due to repeated manipulation. Characteristics of the invention: It consists of a cylindrical container to be attached to the location of the packing gland of the shutter already in use. A system of seals between shutter (cap) and add-on cylindrical body prevents leakage between them. A system of ceramic/graphite seals sliding inside the cylindrical container, static for all purposes, ensures tightness between control shaft and shutter. From said cylindrical body, closed at the top by threaded or flanged plug, emerges an extension rod of adjustable height, inserted onto the underlying shutter control shaft. End use: permanent repair of shutters losing fluid already in use, without removing their piping. IMAGE
