Patentirt im Deutschen Reiche vom 22. Mai 1879 ab.Patented in the German Empire on May 22, 1879.
Die Ventile derjenigen Pumpen, welche bei grofser Kolbengeschwindigkeit einen hohen Druck zu überwinden haben, sind einem starken Verschleifse ausgesetzt, weil die Berührungs- oder Dichtungsflächen von Sitz und Kegel, wenn beide von Metall ausgeführt sind, infolge der Stöfse Unebenheiten erhalten, welche durch das hindurchdringende Wasser in kurzer Zeit zu Einschnitten erweitert werden.The valves of those pumps which produce high pressure at high piston speeds have to overcome, are exposed to strong abrasion, because the contact or Sealing surfaces of the seat and plug, if both are made of metal, as a result of the Get bumpy bumps, which due to the penetrating water in a short time Incisions are expanded.
Bei mäfsigem Druck, bis etwa 8 Atmosphären, wird zur Beseitigung dieses Uebelstandes ein weiches Mittel, Leder, Gummi, Guttapercha oder Holz, als Ueberzug eines der beiden Theile erfolgreich angewendet; für höheren Druck ist dieses aber nicht mehr zulässig, weil dasselbe durch den heftigen Schlag zwischen zwei Metallflächen in kurzer Zeit zerstört wird, zumal die Ueberdeckungsflächen so klein als möglich zu nehmen sind.At moderate pressure, up to about 8 atmospheres, this inconvenience is eliminated a soft agent, leather, rubber, gutta-percha, or wood, successfully used as a coating on one of the two parts; for higher However, this is no longer permissible under pressure, because the same is caused by the violent blow between two metal surfaces is destroyed in a short time, especially since the cover surfaces are as small as are possible to take.
Durch die- Construction der Ring- und Etagenventile wird zwar die Heftigkeit des Schlages vermindert, indem infolge des grofsen Durchgangsquerschnittes der Hub der einzelnen Ringe bedeutend kleiner wird als derjenige der Kegel der Teller- und Glockenventile, aber die mangelhafte Führung der ersteren macht grofse Deckungsflächen erforderlich, und der Schlufs wird erst durch den wiederkehrenden Wasserdruck herbeigeführt, da eine Feder zur Beschleunigung des Falles nicht vorhanden ist.Because of the construction of the ring and floor valves, the force of the blow is increased reduced by the stroke of the individual rings due to the large passage cross-section It becomes significantly smaller than that of the cone of the poppet and bell valves, but the defective one The guidance of the former necessitates large areas of cover, and the closure is only made by the recurring water pressure brought about because there is no spring to accelerate the fall.
Die dargestellte Construction begegnet diesen Uebelständen in folgender Weise. Die Metallringe A1 A2 A3 ruhen auf den Dichtungsflächen des aus Metall hergestellten Sitzes B, so dafs die überdeckenden Lederringe C1 C1 C3 gegen die Wirkung des Schlages geschützt sind, unter allen Umständen aber eine vollkommene Dichtung bewirken, da der Wasserdruck durch die Metallringe D1 D1 D3 auf die ganze Fläche derselben vertheilt wird. Ferner werden die Ringe doppelt geführt, einzeln durch die geneigte Fläche der Ringe C1 C2 C3 und des Sitzes B, und gemeinschaftlich durch das Kreuz E, dessen Büchse den Bolzen F umschliefst. Die Ueberdeckungsfläche des Leders, welche allein den Ueberdruck erzeugt, weil die Metallflächen nicht vollkommen dicht auf einander liegen, kann also möglichst klein genommen werden. Endlich bedingt die gemeinschaftliche Hubbegrenzung durch das Kreuz C, welches gegen den Bolzen F anstöfst, eine beständig waagrechte Lage der Ringe, und durch den Druck der Schraubenfeder G wird der Verschlufs herbeigeführt, bevor die rückgängige Bewegung des Kolbens beginnt, so dafs dieser ohne Stofs erfolgt.The construction shown meets these evils in the following way. The metal rings A 1 A 2 A 3 rest on the sealing surfaces of the seat B made of metal, so that the overlapping leather rings C 1 C 1 C 3 are protected against the impact of the impact, but under all circumstances produce a perfect seal because of the water pressure by the metal rings D 1 D 1 D 3 is distributed over the entire surface of the same. Furthermore, the rings are guided twice, individually through the inclined surface of the rings C 1 C 2 C 3 and the seat B, and collectively through the cross E, the bushing of which surrounds the bolt F. The covering surface of the leather, which alone creates the overpressure because the metal surfaces are not completely close to one another, can therefore be made as small as possible. Finally, the joint stroke limitation by the cross C, which abuts against the bolt F, causes the rings to be in a constant horizontal position, and the pressure of the helical spring G causes the closure before the reciprocating movement of the piston begins, so that it takes place without material .
