Description

Ein als bekannt vorausgesetztes Membranregelventil a wird mittels einer Rohrleitung b einmal mit dem Wasserbehälter c und einmal mit der Speiseleitung d verbunden. Im Wasserbehälter c wird am Ende der Steuerleitung b ein Ventil oder Schieber durch einen Schwimmer f, der in einem Beruhigungsbehälter i geführt wird, von der Flüssigkeitshöhe derart gesteuert, daß der .Wasserdruck infolge gesteuertem Abfluß in der Verbindungsleitung bzw. Steuerleitung b verschieden hoch gehalten wird.A presumed to be known diaphragm control valve a is by means of a pipe b once with the water tank c and once with the feed line d connected. In the water tank c is a valve or at the end of the control line b Slide by a float f, which is guided in a calming tank i, controlled by the liquid level in such a way that the .Wasserdruck as a result of controlled Outflow in the connecting line or control line b held at different levels will.

Der Druck in der Steuerleitung b wird von der Speiseleitung über die Leitung g hergestellt. Die Querschnitte einer Stauscheibe h oder der Rohrleitung g werden der Öffnung e der Steuerung angepaßt, d. h. bei e ist der Querschnitt größer. Die Arbeitsweise erfolgt derart, daß bei gefülltem Behälter oder gewünschtem Wasserstand die Leitung b oben abgeschlossen wird, wodurch der Druck in der Leitung b ansteigt und das Ventil a schließt. Ist der Behälter leer, so ist die Leitung b oben offen, der Durchfluß bei g kleiner, als oben bei größerem Querschnitt e abfließen kann, wodurch in der Steuerleitung b ein geringerer Wasserdruck vorhanden ist und das Regelventil a öffnet. Die Steuerkraft wird durch Widerstand erzeugt, d. h. durch Differenzdruck, der zwischen den Leitungen b und j vorhanden ist. Bei Handeinstellung kann beim Schließen von Ventil r das Regelventil a geöffnet werden, oder bei offenem Ventil i und Schließen von Ventil 2 kann das Regelventil a geschlossen werden. Bei automatischer Einstellung sind Ventil i und 2 offen. Ventil 3 dient zur Entwässerung und zur Kontrollöffnung des Regelventils.The pressure in control line b is taken from the feed line via the Line g established. The cross-sections of a baffle plate h or the pipeline g are adapted to the opening e of the control, i.e. H. at e the cross-section is larger. It works in such a way that when the container is full or the water level is desired the line b is closed at the top, whereby the pressure in the line b increases and valve a closes. If the container is empty, line b is open at the top, the flow at g is smaller than it can flow off above with a larger cross-section e, whereby there is a lower water pressure in the control line b and that Control valve a opens. The control force is generated by resistance, i. H. by Differential pressure existing between lines b and j. With manual adjustment control valve a can be opened when valve r is closed, or when it is open Valve i and closing valve 2, the control valve a can be closed. at automatic setting, valves i and 2 are open. Valve 3 is used for drainage and to the control opening of the control valve.

PATENTANSPRUCH: Vorrichtung zum Regeln des Flüssigkeitsstandes in Behältern, insbesondere in Dampfkesseln, gekennzeichnet durch ein Membranventil in der Speiseleitung, auf dessen Membran einerseits der das Ventil öffnende Druck der Speiseleitung hinter dem Ventil und in entgegengesetztem Sinne der Druck einer zum Behälter führenden Leitung (b) wirkt, deren Öffnung hier durch ein Schwimmerventil in Abhängigkeit vom Flüssigkeitsstand geändert wird und die über eine Leitung (g) mit einer Drosselstelle (h) mit der Speiseleitung (d) vor dem Ventil verbunden ist. PATENT CLAIM: Device for regulating the liquid level in containers, especially in steam boilers, characterized by a diaphragm valve in the feed line, on the membrane of which the pressure of the feed line opening the valve behind the valve and, in the opposite sense, the pressure of a line leading to the container (b) acts, the opening of which is changed here by a float valve depending on the liquid level and which is connected to the feed line (d) upstream of the valve via a line (g) with a throttle point (h).
