Beschreibung
Zusammenfassung:	FIELD: plumbing fittings; water valves with ceramic disks. SUBSTANCE: inner radial stop is made in upper portion of housing. Upper end surface of stop is provided with bore. Lock is fitted in spindle. Projecting part of lock is received by bore. Fluoroplastic ring is fitted between spindle and stop. Ratio of height to diameter of ceramic disks ranges from 0.14 to 0.21. EFFECT: enhanced reliability. Использование: в сантехнической арматуре, в частности в водоразборных вентилях с керамическими дисками. Сущность изобретения: в верхней части корпуса выполнен внутренний радиальный упор. На верхней торцевой поверхности упора выполнена проточка. В шпинделе установлен стопор. Выступающая часть стопора входит в проточку. Между шпинделем и упором установлено фторопластовое кольцо. Отношение высоты к диаметру керамических дисков составляет 0,14 - 0,21.
