Valve for drinkers and automatic drinker provided therewith.

摘要

A feature of the valve is the presence of a metal washer (5) slightly extending from the periphery of the passage of the narrowing (2) of the valve body member (1) avoiding friction of the push member (11) in said narrowing; and the formation, in the upper gasket (12) of a concave bevel (13) where the ball (14) engages, forming a contact area which increases the watertightness of the gasket. It is a feature of the drinker that the bowl (35) and the stem (36) are integral, the stem having a cruciform section reinforcing it and facilitating the fall of the water through the lower port (47) of a threaded bushing (40) screwed on a lower tubular extension (43) of the body member (1 sec ) of the valving device (1 min ) on which extension there is also threaded a locknut (45) ensuring the position of the threaded bushing (40). A version having a single rigid gasket (8 min ) with elimination of the washer (5) is contemplated. <IMAGE>
