FIELD: transportation. ^ SUBSTANCE: cock comprises body with "inlet" and "outlet" nozzles, stem, tube valve. In closed cock, contact butt of tube valve rests on packing insert of support. Butt ends areas of the valve are made equal. The valve has toothed coupling with the stem. The latter is mounted in cock body at right angle to valve axis. This provides reciprocating movement of valve. Support at the centre has press-fitted packing insert. Peripheral part of support has spokes that serve for "outlet" screwing into nozzle. Space between spokes serves for liquid medium flowing. ^ EFFECT: decrease in control force and reduction of control execution time. ^ 3 dwg |
