Vorrichtung zur verlustarmen Einstellung von PluidströmenDevice for low-loss adjustment of fluid currents

Die Erfindung betrifft eine Vorrichtung zur verlustarmen Einstellung von Pluidströmen. Absperrvorrichtungen konventioneller Bauart besitzen hohe Druckverlustbeiwerte infolge starker Strömungsumlenkungen und Strömungsablenkungen an Dichtkörper und Ventilsitz. Die Ablösestellen sind dabei meist unzweckmäßig angeordnet.The invention relates to a device for low-loss adjustment of positive currents. Shut-off devices more conventional Design have high pressure loss coefficients as a result of strong flow deflections and flow deflections on sealing body and valve seat. The separation points are usually arranged inappropriately.

Im Rahmen von Einsparungsmaßnahmen zur Senkung von Betriebskosten bei chemischen oder energietechnischen Anlagen ist es notwendig, Strömungsirreversibilitäten weitgehenst zu vermindern. Aufgabe der Erfindung ist der Aufbau einer Armatur mit geringen Strömungsverlusten, kompakter Bauweise und einfacher Herstellung.As part of savings measures to reduce operating costs in chemical or energy-technical systems, it is necessary to reduce flow irreversibilities as far as possible. The object of the invention is the construction of a valve with low flow losses, compact design and simple manufacture.

Der düsenförmige Ventilkörper (1) ermöglicht eine gute Umsetzung der kinetischen Strömungsenergie in potentielle Druckenergie im erweiterten Teil der Düse. Der Ventilsitz (6) wirkt als definierte Ablösekante (Effekt des sog. Stolperdrahtes bei Tragflügeln) und bewirkt ein besseres Anliegen der Strömung im Expansionsteil der Düse. Die gleichen Überlegungen gelten auch für den stromlinienförmig ausgebildeten Schließkörper (5)· Durch Drehen der Hohlspindel (J>), die sich auf einem Körper (2) beweglich abstützt, kann der Schließkörper axial und translatorisch bewegt werden. Ein Schneckenrad bewirkt die Verstellung der Hohlspindel über den ZahnkranzThe nozzle-shaped valve body (1) enables a good conversion of the kinetic flow energy into potential pressure energy in the enlarged part of the nozzle. The valve seat (6) acts as a defined detachment edge (effect of the so-called tripwire on airfoils) and causes the flow to be better positioned in the expansion part of the nozzle. The same considerations also apply to the streamlined closing body (5). By turning the hollow spindle (J>), which is movably supported on a body (2), the closing body can be moved axially and translationally. A worm wheel adjusts the hollow spindle via the gear rim

Claims (1)

Anspruch;Claim; Die Erfindung ist dadurch gekennzeichnet, daß ein düsenförmiger Körper (1) mit strömungsgünstig angeordneter Ablösekante (6) verwendet wird, wobei
