Description

Geräuscharme und vollentlastete Receiverti!-Bauart für verfahrenstechnische Anlagen.Low-noise and fully relieved Receiverti! Design for process engineering systems.

Beschreibung:Description:

Bei der vorgeschlagenen neuartigen Regelventil-Bauart wird das bekannte Prinzip des feststehenden Kegels und der beweglichen Sitzbuchse angewendet.In the proposed new type of control valve, the well-known principle of the fixed cone and the movable Seat bushing applied.

Im Gegensatz zu den bekannten Ausführungen wird jedoch die Sitzbuchse(T) über ein innenliegendes eingeschv/eißtes St egkreuz(2) von der innen, mittig geführten Antriebs-Ventilstange(3) bewegt.In contrast to the known designs, however, the seat bushing (T) is fitted with an internal, welded-in crosspiece (2) moved by the drive valve rod (3), which is guided in the center.

Die angeschraubte oder angeflanschte Führungsbuchse (Zf) dient gleichzeitig zum Befestigen der Gleitdichtung (5) und als Führung der Sitzbuchse (-1) bzw. der fest damit verbundenen Antriebs-Ventilstange (3). Eine zweite Führung der Antriebs-Ventilstange (j?) erfolgt in der Stopfbuchse (6).The screwed-on or flanged-on guide bushing (Zf) serves at the same time to fasten the sliding seal (5) and as a Guide the seat bushing (-1) or the firmly connected Actuator valve rod (3). The drive valve rod (j?) Is guided a second time in the stuffing box (6).

Der Parabolkegel (7) ist in dem Stützkegel (8) eingschraubt, der wiederum mittels der Stege (9) im Ventilgehäuse (10) eingegossen ist. Der Einlaßbogen (11) mit Befestigungsstutzen (12) und Stopfbuchse (6) wird an das Ventilgehäuse (10) angeflanscht.The parabolic cone (7) is screwed into the supporting cone (8), which in turn is cast in the valve housing (10) by means of the webs (9). The inlet bend (11) with fastening nozzle (12) and the stuffing box (6) is flanged to the valve housing (10).

Das eingschraubte Leitblech (13) dient zur Strömungsführung.The screwed-in guide plate (13) is used to guide the flow.

Zum Antrieb der Antr .ebs-Ventilstange kann jede bev/ährte Antriebs-Bauart wie z.B. Kolben.Antrieb, Membran-Antrieb, Motor-Antrieb etc. verwendet werden. Wegen der vollentlasteten Bauart können hierbei für alle Dimensionen relativ kleine und leichte Antriebe verwendent werden.Any well-proven actuator type can be used to drive the actuator e.g. piston drive, diaphragm drive, motor drive etc. be used. Because of the fully relieved design, relatively small and light drives can be used for all dimensions will.

Grundsätzlich werden durch diese neuartige Regelventil-Bauart folgende Vorteile ermöglicht:Basically, this new type of control valve enables the following advantages:

a) Sehr günstiges Strömungsprofil bei der Entspannung und damit sehr geräuscharm und außerdem sehr günstiger c -Wert.a) Very favorable flow profile during expansion and therefore very low-noise and also very favorable c value.

b) Vollentlastete Bauart mit bewährtem Parabolkegel und ohne schrautzempfindliche Bohrungen,Nuten,Schlitzkegel o.a.b) Fully balanced design with tried and tested parabolic cone and without holes, grooves, slotted cones or the like that are sensitive to pollution

c) Beherrschung extremer Nennweiten, Differenzdrücke, Dichtschließ-Bedingungen und Temperaturen mit kleinen Antrieben und damit preisgünstiger Ausführung. c) Control of extreme nominal widths, differential pressures, tight-closing conditions and temperatures with small actuators and thus inexpensive design.

d) Weitestgehende Schmutzunempfindlichkeit durch Selbstreinigungs-Effekt infolge der günstigen Strömungsführung.d) Largely insensitive to dirt due to self-cleaning effect due to the favorable flow guidance.

e) Einfache Wartungs und Reperaturarbeiten, weil Austausch von Kegel, Gleitdichtung und Sitzbuchse ohne Abbau des Antriebes möglich sind.e) Easy maintenance and repair work because the cone is replaced, Sliding seal and seat bushing are possible without dismantling the drive.

f) Wegen Anwendbarkeit für größte Nennweiten und sehr günstigem c -Wert eine echte Ventil-Alternative zu den Regelklappen.f) Because it can be used for the largest nominal sizes and very inexpensive c value is a real valve alternative to control dampers.
