KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Der Zweck der vorliegenden Erfindung ist, ein Undichtwerden von Ventilen durch beständiges Abschleifen infolge der mit grofser Geschwindigkeit an den Dichtungsflächen durchströmenden Massen zu verhüten.The purpose of the present invention is to prevent valve leakage through persistent Abrasion as a result of the flow through the sealing surfaces at high speed To prevent crowds. Letzteres ist erfahrungsgemäfs die Ursache von Riefen, welche an Sitz und Kegel sichtbar werden. Vorzugsweise tritt diese Wirkung während der Dauer des Oeffhens des Ventils und bei gedrosseltem Ventil ein infolge der hiermit verbundenen gröfseren Durchströmungsgeschwindigkeit der Massen, aber auch bei normal geöffnetem Ventil.Experience has shown that the latter is the cause of scoring visible on the seat and cone will. This effect preferably occurs while the valve is open and when the valve is throttled, a result of the associated higher flow velocity of the masses, but also when the valve is normally open. Um nun die Dichtungsflächen dieser reibenden Wirkung zu entziehen, ist die Sitzfläche am Kegel von den Wänden α und b eingeschlossen, am Sitz aber leitet die Wand c die Strömung über die Dichtungsfläche hinweg. Die Wand α geht mit ganz leichtem Spielraum im Sitz s, so dafs beim Oeffnen des Ventils nur ein ganz geringer Durchströmungsquerschnitt entsteht, die Masse aber über c hinaus sofort zur Ausdehnung und zur Annahme einer geringen Geschwindigkeit gezwungen wird.In order to remove this frictional effect from the sealing surfaces, the seat surface on the cone is enclosed by the walls α and b , but at the seat wall c directs the flow over the sealing surface. The wall α goes with a very slight margin in the seat s, so that when the valve is opened only a very small flow cross-section is created, but the mass beyond c is immediately forced to expand and to assume a low velocity. Pateντ-Anspruch:Pateντ claim: Hubventil, dessen Dichtungsflächen mit ringförmigen Schutzwänden (a und b) am Kegel und (c) am Sitz derart versehen sind, dafs die Dichtungsflächen des Ventils der abschleifenden Wirkung der durchströmenden tropfbaren oder gasförmigen Flüssigkeit nicht ausgesetzt sind.Lift valve, the sealing surfaces of which are provided with annular protective walls (a and b) on the cone and (c) on the seat in such a way that the sealing surfaces of the valve are not exposed to the abrasive effect of the dripping or gaseous liquid flowing through.
