PATENTAMT^PATENT OFFICE ^
Das dargestellte Absperrventil wird mit dem unter No. 61654 geschützten Ventil vermittelst der Verschraubung C in Verbindung gebracht.The shut-off valve shown is connected to the number given under No. 61654 protected valve by means of the screw connection C.
B ist das Vierkant, von dem das Ventil geöffnet und geschlossen wird. Die hohle Ventilspindel B ist oben mit einem Ventilgehäuse, welches gleichzeitig als Handrad zum Oeffnen und Schliefsen des Ventils dient, versehen. B is the square from which the valve is opened and closed. The hollow valve spindle B is provided with a valve housing at the top, which also serves as a handwheel for opening and closing the valve.
In dem Ventilgehäuse befindet sich ein hydraulischer Cylinder F mit zwei verschieden grofsen Bohrungen, in welchen sich die Kolben M und N auf- und abbewegen können.In the valve housing there is a hydraulic cylinder F with two bores of different sizes in which the pistons M and N can move up and down.
Auf dem Flantsch des Cylinders F ist eine Membrane D aufgelöthet; zum Schutz für letztere ist oben eine Metallscheibe E lose aufgelegt. O sind Aussparungen im Deckel H, in welchen noch Federn angebracht werden können; diese Aussparungen stehen durch Löcher mit der Atmosphäre in Verbindung.A membrane D is soldered onto the flange of the cylinder F; To protect the latter, a metal disk E is loosely placed on top. O are recesses in the cover H, in which springs can still be attached; these recesses are in communication with the atmosphere through holes.
In dem Raum zwischen den beiden Kolben M nnd N befindet sich eine Flüssigkeit, bestehend aus einer Mischung von Glycerin und Gelatine, welche bezweckt, beim Oeffnen des Ventils als elastisches Kissen zu wirken.In the space between the two pistons M and N there is a liquid consisting of a mixture of glycerine and gelatin, which aims to act as an elastic cushion when the valve is opened.
Die obere weitere Ausbohrung von B ist zur Aufnahme des Ventils J, welches mit seitlichen Nuthen T versehen ist, um den Durchtritt des Gases nach dem Raum L zu ermöglichen. Die Ventilspindel / ist oben mit einem Bund versehen, gegen den sich eine Feder K legt, die das Bestreben hat, J immer nach oben gegen den Kolben N zu drücken.The upper further bore of B is for receiving the valve J, which is provided with lateral grooves T to allow the passage of the gas to the space L. The valve spindle / is provided at the top with a collar against which a spring K rests, which tends to always push J upwards against the piston N.
Bei geöffnetem Ventil tritt das Gas durch die Bohrungen der Spindel B, hebt das Ventil J und tritt durch die seitlichen Nuthen T nach oben in den Raum L unter die Membrane D. When the valve is open, the gas passes through the bores of the spindle B, lifts the valve J and passes up through the lateral grooves T into the space L under the diaphragm D.
Infolge dessen wird D gehoben und mit ihr zugleich der hydraulische Cylinder F. Da der Kolben M nicht mit nach oben sich bewegen kann, so verursacht der Uebergang der Flüssigkeit von dem grofsen in den kleinen Cylinder ein Abwärtsbewegen des Kolbens N mit grofser Kraft, wodurch sich das Yentil nach unten bewegt.As a result, D is lifted, and with it the hydraulic cylinder F. Since the piston M cannot move upwards with it, the passage of the liquid from the large to the small cylinder causes the piston N to move downwards with great force, whereby the yentil moves down.
Wenn der Gasdruck in L gefallen ist, ■ so geht der hydraulische Cylinder wieder nach unten, und das Ventil / geht in seine frühere Stellung nach oben.When the gas pressure in L has fallen, the hydraulic cylinder goes down again and the valve / goes up to its previous position.
Durch das Steigen oder Fallen des Druckes in L wird also die Ausströmungsöffnung des Ventils J verengt oder erweitert.As the pressure in L rises or falls, the outflow opening of valve J is narrowed or widened.
Der hydraulische Cylinder kann auch noch bei Dampfwasserableitern u. dergl. Verwendung finden.The hydraulic cylinder can also be used in steam water traps and the like Find.
