Abstract

Improvements in bonded plug valves, characterized in that said valves comprise, a casing having a conduit passing through it for the flow of fluid and a conical bore intersecting said conduit, a conical plug mounted to rotate in said conical bore, intended to block the duct in the closed valve position of the plug, the plug of which has a port intended to be connected and establish communication with the duct in the open position of the valve, the plug and housing defining a chamber at one end of the plug, a stem mounted to rotate inside the housing mechanically coupled to the plug to rotate the plug, said housing having an annular rib surrounding the stem at one end of the chamber, the stem having an annular rim and being located on the part of the stem that is in said chamber, a thrust bearing and annular obturator surrounding the stem and abutting with the opposing side faces: of the annular rib and the annular flange to form a hermetic seal therebetween.
