KAISERLICHESIMPERIAL PATENTAMTPATENT OFFICE Gegenstand vorliegender Erfindung bildet ein Schauglas, welches über die verlängerte Ventilspindel gestülpt, mit Gradtheilung versehen ist und infolge seiner Durchsichtigkeit die Einsichtnahme in das Spiel des Ventils gestattet. Das Ventil α ist mit einem Fortsatz b versehen, welcher vortheilhaft an seinem oberen Ende durch eine aus elastischem Material gefertigte Kappe c verbreitert ist und eine solche Länge besitzt, dafs der Fortsatz in Ruhelage und beim Spielen des Ventils aufserhalb des Ventilgehäuses d sichtbar wird.The subject of the present invention is a sight glass, which is placed over the extended valve spindle, is provided with degree graduation and, due to its transparency, allows viewing into the play of the valve. The valve α is provided with an extension b , which is advantageously widened at its upper end by a cap c made of elastic material and is of such a length that the extension is visible outside the valve housing d in the rest position and when the valve is playing. Ueber dem Ventilfortsatz b ist ein oben geschlossenes Schauglas e gestülpt, welches mit sichtbarer Gradtheilung f versehen ist und mittelst geeigneter Stopfbüchse g in dem Ventilgehäusedeckel abgedichtet ist.An inspection glass e closed at the top is placed over the valve extension b , which is provided with a visible graduation f and is sealed in the valve housing cover by means of a suitable stuffing box g. Das Schauglas e ist in der Stopfbüchse in Längsrichtung verschiebbar. Dasselbe läfst infolge seiner Durchsichtigkeit und infolge der Anordnung des Fortsatzes b in Verbindung mit der Kappe c das Spiel des Ventils bei der Bethätigung des Pumpwerks oder der sonstigen Vorrichtung erkennen, und läfst erkennen, wenn letzteres ungenau oder unvorschriftsmäfsig arbeitet. Da ferner das Schauglas e in der Stopfbüchse g senkrecht verschiebbar und oben abgeschlossen ist, so kann durch entsprechendes Einstellen des Schauglases der Hub des Ventils eventuell geregelt werden. Das Schauglas e hat eine solche Weite, dafs der Ventilfortsatz b und die Kappe c in demselben mit Spielraum arbeiten und Luft bezw. Flüssigkeit in seinem Innern circuliren kann.The sight glass e can be moved lengthways in the stuffing box. As a result of its transparency and the arrangement of the extension b in conjunction with the cap c, the play of the valve when the pumping mechanism or other device is operated can be recognized and if the latter is working imprecisely or improperly. Furthermore, since the sight glass e is vertically displaceable in the stuffing box g and is closed at the top, the stroke of the valve can possibly be regulated by adjusting the sight glass accordingly. The sight glass e has such a width that the valve extension b and the cap c work in the same with clearance and air or. Fluid can circulate inside it. Patenτ-Anspruch:Patenτ claim: Ein oben geschlossenes, gegebenenfalls mit Theilung versehenes Schauglas für Ventile, welches, auf dem Deckel des Ventilgehäuses angebracht, den Ventilfortsatz b mit allseitigem Spielraum aufnimmt, um das Spiel des Ventils sichtbar zu machen, und durch Längsverstellung den Ventilhub zu regeln gestattet.A sight glass for valves, closed at the top, optionally provided with a dividing, which, attached to the cover of the valve housing, accommodates the valve extension b with all-round clearance to make the play of the valve visible and to regulate the valve stroke by longitudinal adjustment.
