Description

H. GRUSON in BUCKAU bei MAGDEBURG. Neuerungen an Hornblower'schen Rohrventilen. H. GRUSON in BUCKAU near MAGDEBURG. Innovations in Hornblower pipe valves.

Patentirt im Deutschen Reiche vom 24. Februar 1878 ab.Patented in the German Empire on February 24, 1878.

Dieses Ventil bezweckt eine möglichst vollkommene Beseitigung der Uebelstände, die den bisherigen Admissions ventilen anhaften.The aim of this valve is as complete as possible the elimination of the troubles which the previous admissions valves stick.

In der beiliegenden Zeichnung stellen die Fig. ι und 3 zwei Verticalschnitte und Fig. 2 einen Horizontalschnitt dar, während Fig. 4 eine Ansicht und einen Horizontalschnitt des nackten Ventilkörpers zeigt.In the accompanying drawing, FIGS. 1 and 3 represent two vertical sections and FIG. 2 represents a horizontal section, while Fig. 4 is a view and a horizontal section of the naked Valve body shows.

Der Dampfeintritt erfolgt durch das horizontale Rohrstück a, der Austritt durch die untere Oeffmmg b. Das Absperrventil c, welches durch Flügel in dem Rohr α geführt ist, wird mittelst des Handrades d geschlossen und beim Zurückschrauben desselben durch den Dampfdruck geöffnet. The steam enters through the horizontal pipe section a, the exit through the lower opening b. The shut-off valve c, which is guided by vanes in the tube α , is closed by means of the handwheel d and opened by the steam pressure when it is screwed back.

Der über dem oberen Sitz e befindliche Raum ist mit dem unterhalb des Sitzes f gelegenen Raum durch zwei Seitenkanäle gg verbunden.The space above the upper seat e is connected to the space below the seat f by two side channels gg .

Der Ventilkörper, Fig. 4, besteht aus einem oben mit Durchbrechungen versehenen Metallrohr, das in der Nähe des unteren Endes eingeengt ist. Quer durch das Rohr geht ein horizontaler Kanal h, durch welchen die Spindel des Absperrventils dringt. Der Ventilkörper ist genau cylindrisch abgedreht, so dafs der untere Rand mit dem oberen cylindrischen Theil einerlei Durchmesser besitzt. Mit diesem Durchmesser stimmt auch die lichte Weite der beiden Sitze e und f über ein.The valve body, Fig. 4, consists of a metal tube provided with openings at the top and narrowed near the lower end. A horizontal channel h, through which the spindle of the shut-off valve penetrates, passes through the pipe. The valve body is turned exactly cylindrical, so that the lower edge and the upper cylindrical part have the same diameter. The clear width of the two seats e and f also coincides with this diameter.

Die sämmtlichen Doppelsitzventile, sowie das Rohrventil von Hornblower u. s. w., zeigen für Dampf bei schwacher Oeffnung eine unvollständige Entlastung, herrührend von einer Druckabnahme des bewegten Dampfes in der Nähe des einen Sitzes. Ueberdies erzeugt der Temperatur-Unterschied des gedrosselten und frischen Dampfes, sowie die verschiedene Wärmeausdehnung der Metalle, bald ein Klemmen, bald eine Undichtigkeit des Kegels. Der erste Uebelstand, der sich hier als Druckabnahme gegen den unteren Ventilrand äufsern müfste, ist durch den Stofs des nach unten gerichteten Dampfstrahles compensirt. Der zweite, in einer zu starken Wärme-Ausdehnung des Ventilkörpers bestehende, wird dadurch aufgehoben, dafs bei völligem oder annäherndem Schliefsen ein Zusammendrücken des Ventilkörpers durch den äufseren Dampfdruck erfolgt.The entire double seat valves, as well as the pipe valve from Hornblower and so on, show for steam with a weak opening, incomplete relief, resulting from a decrease in pressure of moving steam near one seat. In addition, the temperature difference between the throttled and fresh steam, as well as the various thermal expansion of the metals, soon a jamming, soon a leak in the cone. The first problem, which is shown here as a decrease in pressure against the lower edge of the valve is through the fabric of the downward facing Steam jet compensated. The second, in excessive thermal expansion of the valve body existing ones are abolished by the fact that when they are completely or nearly closed, they are compressed of the valve body takes place through the external steam pressure.
