PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf eine Ventildichtung, bei welcher ein Metallring zur
Verwendung kommt, gegen welchen sich das Ventil beim Schließen anlegt.
Alle bisherigen Ventildichtungen dieser Art weisen den Übelstand auf, daß die Metallringe
beim Schließen des Ventils ausweichen können, woraus sehr bald Undiclilhcitc-n entstehen. Es
hat aus diesem Grunde bisher meistens an ίο einem Ventil gefehlt, welches, besonders bei
flüchtigen Körpern, einen guten und vor allem dauernd dichten Abschluß sichert.The present invention relates to a valve seal in which a metal ring is used, against which the valve rests when closing.
All valve seals of this type to date have the disadvantage that the metal rings can give way when the valve is closed, which very soon results in undecleaning. For this reason, until now there has mostly been a lack of a valve which, especially in the case of volatile bodies, ensures a good and, above all, permanently tight seal.
Gemäß vorliegender Erfindung soll nunAccording to the present invention should now
diesem Mangel dadurch abgeholfen werden, daß man als Dichtungsmittel einen weichen MetalljmTg_ verwendet und "diesen 'derart inthis defect can be remedied by reacting ungsmittel used as sealing a soft MetalljmTg_ and "this" in such a way
v~einer Aussparung des Ventilsitzes anordnet, daß er bei gesperrtem Ventil von allen Seiten eingeschlossen ist. Um dies in vollkommenster Weise zu erzielen, erhält das Ventil einen kegeligen Teil, an welchen sich nach oben und unten zylindrische Teile anschließen. v ~ a recess in the valve seat is arranged so that it is enclosed on all sides when the valve is closed. In order to achieve this in the most perfect way, the valve is given a conical part to which cylindrical parts are connected upwards and downwards.
Es ist klar, daß nach einer bestimmten Einpressung des weichen Metallringes dieser eine so große Dichte erreicht, daß keine weitere Verminderung seiner Größe möglich ist, wodurch eine dauernde Dichtheit erzielt wird. · Um auch bei geöffnetem Ventil eine gute Abdichtung der Stopfbüchse zu erzielen, wird vorteilhaft in eine Aussparung der Stopfbüchse ein Dichtungsring eingelegt, gegen welchen sich ein ringförmiger Aufsatz des Ventils / . preßt. - ■' ■ -. : : ■■■ ■. :'.' - .■·/' ■ '■■..■. It is clear that after the soft metal ring has been pressed in a certain way, the latter reaches such a high density that no further reduction in its size is possible, whereby a permanent tightness is achieved. · In order to achieve good sealing of the stuffing box even when the valve is open, a sealing ring is advantageously inserted into a recess in the stuffing box, against which an annular attachment of the valve /. presses. - ■ '■ -. :: ■■■ ■. : '.' -. ■ · / '■' ■■ .. ■.
Beiliegende Zeichnung stellt eine AusfUhrimgsforni der neuen Ventildichtung dar.The enclosed drawing represents an execution form the new valve seal.
Der Ventilsitz α ist mit einer Aussparung versehen, in welche ein weicher Metallring b eingelegt ist. Reim Schließen des Ventils 'c drückt sein kegeliger Teil gegen den Ring b und letzterer ist bei gesperrtem Ventil auf allen Seilen vollständig eingeschlossen, was durch die zylindrischen Fortsetzungen des Ventils oberhalb und unterhalb des Kegelstumpfes bewirkt wird. Ein Verschieben oder Verdrehen des Ringes b ist hierbei ausgeschlossen, und es ist somit eine gute und dauernde Dichtung gesichert.The valve seat α is provided with a recess into which a soft metal ring b is inserted. Reim closing the valve 'c expresses its tapered part against the ring B and the latter is completely enclosed with blocked valve on all ropes, which is effected by the cylindrical continuations of the valve, above and below the truncated cone. A shifting or twisting of the ring b is excluded here, and a good and permanent seal is thus ensured.
Der Ring b kann beliebig geformt werden.The ring b can be shaped as desired.
Bei geöffnetem Ventil tritt ein ringförmiger Aufsatz in eine Aussparung der Stopfbüchse e ein und preßt gegen einen in diese Aussparung eingelegten Dichtungsring d. When the valve is open, an annular attachment enters a recess in the stuffing box e and presses against a sealing ring d inserted in this recess.
