Abstract

TECHNOLOGICAL FIELD: Mechanical/Hydraulic. TECHNICAL PROBLEM: To reduce the number of components and slowness of assembly of a typical gate valve, eliminates a coupling surface which over time can become a source of leakage of the liquid, and simultaneously achieve complete fluidtightness using ceramic graphite seals. CHARACTER OF THE INVENTION: It is well known that a gate valve for use in fluid pipes traditionally consists of a body, and a stuffing box that compresses an impregnated cord or tow in the seat and around the control shaft, thus preventing leakage of the fluid but only for a short while. The invention consists in a particular configuration of the colour which does away with the stuffing box, the stuffing box fixing bolts and the impregnated cord or tow. Fluidtightness inside the cover is provided by a set of ceramic/graphite seals which prevent all leaks for a long period of time. USE: Industrial manufacture of gate valves without stuffing boxes while achieving complete fluidtightness. <IMAGE>
