Vorrichtung zum Öffnen und Schliessen von Absperrorganen von DrucMussigkeitsleitungen.
Es ist bekannt, das Offnen und Schliessen von Absperrorganen von Druckflüssigkeitsleitungen durch einen von der Druckflüssigkeit selbst betriebenen Arbeitszylinder besorgen zu lassen, indem man den Kolben dieses Zylinders mit dem beweglichen Teil des Absperrorgans mittelbar oder unmittelbar verbindet. Da der Bewegungswiderstand beim Beginn des Eröffnen und gegen das Ende des Schliessens bedeutend grösser ist als auf den übrigen Teilen des Weges, so mussten die Abmessungen des Arbeitszylinders jenem nur auf einem verhältnis-

Device for opening and closing shut-off devices of pressure fluid lines.
It is known to have the opening and closing of shut-off devices of pressure fluid lines taken care of by a working cylinder operated by the pressure fluid itself by connecting the piston of this cylinder to the movable part of the shut-off device directly or indirectly. Since the resistance to movement at the beginning of opening and towards the end of closing is significantly greater than on the other parts of the path, the dimensions of the working cylinder only had to be based on that
EMI1.1
larger shut-off devices led to extensive and expensive structures.
According to the invention, however, the working cylinder only needs to be adapted in terms of its dimensions to the average resistance to movement, because it is necessary to overcome the
EMI1.2
Increases in resistance by a pump or other device for increasing the pressure, e.g. B. a multiplier is supported, whereby the working cylinder fluid of higher pressure than that of the hydraulic fluid. can be supplied intermittently whenever necessary. The pump, which is preferably to be driven by human power, as well as the multiplier or the like, can be connected to the pressure line itself and presses hydraulic fluid of increased pressure into the working cylinder, and only for as long as it is necessary to overcome the great resistance, while the drive is otherwise can be left to the working cylinder.
The reduction in the dimensions of the working cylinder made possible in this way is by no means economically compatible with the addition of a small hand pump or the like.
