Absperrventil

摘要

A shut-off valve for liquids and other substances to be attached to the outlet flange of a container, with a cylindrical valve body (2) which extends through the valve housing inclined at an acute angle to the vertical and whose cylindrical guide (14) ends in an upper elliptical opening of the inlet flange (12), with the face (18) of the valve body also exhibiting an elliptical circumference adjusted thereto. Connected to the lower side of guide (14) is a generally vertical cylindrical downpipe (16), and the valve body (2) is turned from its closed position blocking the valve passage by 180 DEG via actuating means and then shifted axially until completely open. During the closing process, which involves the above process in reverse, the circumferential edge of the valve body shaves all material off the sealing ring (3) and the sealing surface (20) prior to reaching the closed position.
