BALL COCK-CONDENSATE ACCUMULATOR

摘要

The invention relates to pipeline valves and accessories, in particular to ball cocks for gas-main and industrial gas pipelines used in transportation of gas containing a condensate with mechanical impurities, said cocks providing, at a predetermined service life, passage of gas, cleaning and diagnosing equipment, reliability in chocking the gas stream against action of mechanical impurities, and removal of the condensate. A ball condensate-picker cock comprises: a welded body with inlet and outlet pipe junctions; a drainage conduit, spindle flanges and a plug drive; a flush rotary-on-supports ball plug; two spring-loaded seats with sealing rings and holders mounted into the pipe junctions so as to interact with a surface of the ball plug. The distinction consists in that the flush rotary-on-supports ball plug being made by different production methods is provided with a central bore of a passage diameter DN having a dimension D 1 larger than an internal diameter D of a header pipe over a length L 1 and with two drain openings having lead-in chamfers positioned at the bore end faces in the center of the plug bottom, and the drainage conduit is made of two - internal and external - parts, the internal part being formed as a curvilinear pipe with a beveled inlet end face and a straight outlet end face welded to a transition for exiting out of the body, wherein the inlet end face is arranged in the center of a bottom of a semi-body and the outlet end face is made of a pipe welded to the body, a ball stopcock, and an outlet pipe junction. This allows to broaden the technical functionality of the cock in part of catching, collecting, and removing the condensate out of the pipeline, prolonging the service life of the cock due to execution of the running and thorough repairs, and also to execute exploitation works for diagnosing the gas pipelines. The set of claims is proposed with two dependent claims. Drawings in Figs 1-10 are submitted.
