1879.1879. Klasse 85.Class 85. HERMANN GOODSON in BERLIN. Automatisches Druckreductionsventil.HERMANN GOODSON in BERLIN. Automatic pressure reduction valve. . Patentirt im Deutschen Reiche vom I. Februar 1879 ab.. Patented in the German Empire on February 1st, 1879. Das durch beiliegende Zeichnung im Schnitt dargestellte Ventil dient zur Verminderung des Druckes, welcher durch Wasser, Dampf oder gespannte Gase in Rohrleitungen verursacht wird.The valve shown in section by the accompanying drawing is used to reduce the Pressure caused by water, steam or pressurized gases in pipelines will. Wird das Ventil in eine Leitung eingeschaltet, was durch Muffen- oder Flantschenverbindungen e geschehen kann, so tritt die durchströmende Materie zunächst durch das untere Ventil c, treibt dasselbe, sowie dessen durch die Stopfbüchse / gehende Führungsstange und den mit derselben zusammenhängenden, im Cylinder m sich' bewegenden Kolben B in die Höhe, füefst durch die zwischen der Aufsenwandung des Apparats und dem Cylinder begrenzten Raum d und gelangt dann in die weitere Rohrleitung g. If the valve is switched on in a line, which can be done by sleeve or flange connections e , the material flowing through first passes through the lower valve c, drives it, as well as its guide rod going through the stuffing box and the guide rod connected to it in the cylinder m moving piston B upwards, passes through the space d delimited between the outer wall of the apparatus and the cylinder and then enters the further pipeline g. Hört der Durchflufs der Flüssigkeit auf, so wirkt diese auf den Kolben B, dessen Druckfläche eine bedeutend gröfsere als die des Ventils A ist, drückend, und bringt das Ventil zum Schliefsen. Dadurch wird der ursprüngliche Druck ' der Flüssigkeit auf die Leitung vor dem Apparat beschränkt, dagegen der Druck hinter demselben bedeutend vermindert.If the flow of the liquid stops, it acts on the piston B, the pressure area of which is significantly larger than that of the valve A , pushing, and brings the valve to close. As a result, the original pressure of the liquid is restricted to the line in front of the apparatus, while the pressure behind it is considerably reduced. Die Dichtungen des Kolbens B, Ventils A und der Stopfbüchse / geschehen in der für diese Vorrichtungen üblichen Weise durch Leder- und Hanfverpackung.The seals of the piston B, valve A and the stuffing box / are done in the usual way for these devices through leather and hemp packaging. Zur Regulirung der Hubbewegung des Kolbens B dient das in dem unteren Theil, unmittelbar über die Bodenfläche des Cylinders m, angebrachte Rohr mit dem daran befindlichen Hahn h und dem Luftventil k; ersterer, h, regulirt die durch die Rückbewegung des Kolbens comprimirte ausströmende Luft, letzteres, k, dient zur Ergänzung derselben bei der saugenden Aufwärtsbewegung des Kolbens B. The tube with the cock h and the air valve k attached to the lower part, directly above the bottom surface of the cylinder m, serves to regulate the stroke movement of the piston B; the former, h, regulates the outflowing air, which is compressed by the return movement of the piston, the latter, k, serves to supplement the same during the sucking upward movement of the piston B. Die Thätigkeit des Luftventils k wird durch den vor demselben angebrachten Hahn / ebenfalls beliebig regulirt.The action of the air valve k is also regulated as desired by the cock / placed in front of it. Die Zeichnung stellt den Apparat in eine gröfsere Zuflufsleitung unter der Erdoberfläche eingeschaltet dar; durch die oben beschriebenen Vorrichtungen kann derselbe durch hik von oben aus in sehr einfacher, praktischer Weise regulirt werden, indem das Rohr g bis zur Erdoberfläche fortgeführt, die daran befindlichen Hähne h und i, sowie das Luftventil k in einem gufseisernen Verschlufskasten /, dessen Oberfläche mit dem Terrain abschneidet, zu liegen kommen. Durch dieses Verfahren ist die richtige Function des Apparates leicht zu controliren, sowie sind etwa entstehende Schäden sofort wahrzunehmen.The drawing shows the apparatus switched into a larger inflow pipe under the surface of the earth; by means of the devices described above, it can be regulated from above in a very simple, practical manner by hik , by extending the pipe g to the surface of the earth, the taps h and i on it, and the air valve k in a cast-iron lock box /, its surface cuts off with the terrain, come to rest. With this procedure the correct function of the apparatus is easy to control, and any damage that may arise is immediately perceptible.
