Abstract

A radiator valve comprises a housing (1) on which are arranged a pipe union (11) for connection to the radiator and a screw socket (13) for receiving the first closure piece (4), which is arranged on a hollow valve spindle (3). The first closure piece (4), together with a valve seat (33) in the housing (1), forms a choke-like preset device for the throughflow. To allow the line or radiator to be emptied through the hollow valve spindle (3), the hollow valve spindle (3) contains a second valve closure piece (5), which can be actuated from the outside against the force of a spring and moved forward from the outside with regard to a corresponding valve seat in the valve spindle (3). The second hollow valve closure piece (5) is double acting and can be moved, with its end (52) opposite the discharge valve seat (33), through the first valve closure piece (4) toward the housing valve seat (14). A controller (9) which acts on the second valve closure piece (4) can be placed on the valve.

Description

"Heizungsventi1" "Heizungsventi1"
Die Erfindung betrifft ein Heizungsventil nach dem Oberbegriff des Anspruches 1, welches in Geradsitz¬ oder Schrägsitzbauweise in Heizungsanlagen mit mehreren Heizkörpern und verschiedenen Strängen vorwiegend im Rücklauf eingesetzt wird, über solche Heizungsventile, die der Absperrung eines Stranges dienen, läßt sich der entsprechende Teil der Anlage entleeren.The invention relates to a heating valve according to the preamble of claim 1, which is used in a straight seat or angled seat construction in heating systems with several radiators and different lines, mainly in the return line, via such heating valves, which serve to shut off a line, the corresponding part of the system can be used empty.
Bekannt ist ein gattungsgemäßes Heizungsventil aus dem DE-GM 71 11 825. Bei diesem Heizungsventil ist im Schraubstutzen des Gehäuses eine ebenfalls der Vorein- Stellung der Durchflußmenge dienende hohle Spindel eingeschraubt, die über eine Schraubkappe gegen den Ventilsitz im Gehäuse zur Absperrung und zur Vorein¬ stellung verschiebbar ist. In der hohlen Ventilspindel ist ein Kugelventil angeordnet, über welches der Strang bzw. ein Heizkörper entleert werden können. Durch die hohle Ventilspindel hindurch kann von außen mit einer aufschraubbaren Entleervorrichtung die Kugel gegen den Druck der Rückstellfeder verschoben und damit von ihrem Ventilsitz im Inneren der Ventilspindel abgehoben werden. Der vordere Teil dieser Ventilspindel dient der Voreinstellung. Mit solchen Heizungsventilen wird durch entsprechende Voreinstellung im jeweiligen Strang den notwendigen Betriebsbedingungen Rechnung getragen. Es zeigt sich jedoch häufig, daß in größeren Anlagen die Betriebsbe¬ dingungen schwanken, so daß eine einmalige Voreinstel¬ lung des Durchflusses unzureichend ist. In der Regel wird dann an der entsprechenden Stelle ein Regelveπtil, meistens ein Membranregler, eingesetzt. Ein solcher nachträglicher Einsatz erfordert hohe Montagekosten.A heating valve of the generic type is known from DE-GM 71 11 825. In this heating valve, a hollow spindle, which also serves for presetting the flow rate, is screwed into the screw socket of the housing and is screwed against the valve seat in the housing for shut-off and for pre-opening position is displaceable. A ball valve is arranged in the hollow valve spindle, via which the line or a radiator can be emptied. The ball can be moved from the outside against the pressure of the return spring through the hollow valve spindle using a screw-on emptying device and can thus be lifted off its valve seat inside the valve spindle. The front part of this valve spindle is used for presetting. With such heating valves, the necessary operating conditions are taken into account by appropriate presetting in the respective branch. However, it is often found that the operating conditions fluctuate in larger systems, so that a one-time presetting of the flow is insufficient. As a rule, a control valve, usually a membrane regulator, is then used at the appropriate point. Such subsequent use requires high assembly costs.
Die Aufgabe der Erfindung besteht darin, ein Heizungs¬ ventil der eingangs genannten Art vorzuschlagen, welches in einfacher Weise mit einem Druckregler kombi¬ nierbar ist.The object of the invention is to propose a heating valve of the type mentioned at the outset, which can be combined in a simple manner with a pressure regulator.
Gelöst wird die Erfindungsaufgabe mit einem Heizungs¬ ventil mit sämtlichen Merkmalen des Anspruches 1.The object of the invention is achieved with a heating valve with all the features of claim 1.
An einem solchen erfindungsgemäßen Heizungsventil, welches als Absperrventil mit Entleerungsfunktion und Voreinstellmöglichkeit eingesetzt werden kann, läßt sich ein Regler ansetzen, ohne daß das Ventilgehäuse oder das Oberteil zu montieren ist. Der Regler greift dabei mit einem entsprechenden Betätigungsglied in die hohle Ventilspindel ein und wirkt gegen das zweite Ver¬ schlußstück in dieser Ventilspindel. Auf einfache Weise kann daher ein solches Heizungsventil zum Regel¬ ventil umgestaltet werden.A controller can be attached to such a heating valve according to the invention, which can be used as a shut-off valve with drainage function and presetting possibility, without the valve housing or the upper part having to be mounted. The controller engages with a corresponding actuating element in the hollow valve spindle and acts against the second closure piece in this valve spindle. Such a heating valve can therefore be converted into a control valve in a simple manner.
Nach einer bevorzugten Ausführungsart der Erfindung gemäß Anspruch 2 läßt sich der Regler am äußeren Ende der Ventilspindel aufsetzen. Der Regler ist damit ge¬ häuseunabhängig und läßt sich in vorteilhafter Weise an verschiedenen Ventilgrößen • mit unterschiedlichen Gehäusen, jedoch gleicher Ventilspindelendgestaltung, einsetzen. In weiterer Ausgestaltung der Erfindung wird gemäß An¬ spruch 4 eine Möglichkeit aufgezeigt, die Voreinstel¬ lung von außen sichtbar zu gestalten. Gemäß Anspruch 5 bilden Schraubkappe und Anzeigering die von außen sichtbare Voreinstellungsanzeige.According to a preferred embodiment of the invention according to claim 2, the controller can be placed on the outer end of the valve spindle. The controller is thus independent of the housing and can be used advantageously on different valve sizes with different housings but the same valve stem end design. In a further embodiment of the invention, according to claim 4, a possibility is shown to make the presetting visible from the outside. According to claim 5 screw cap and indicator ring form the preset display visible from the outside.
Anhand eines abgebildeten Ausführungsbeispieles wird im folgenden die Erfindung näher erläutert. Es zeigen:The invention is explained in more detail below on the basis of an illustrated exemplary embodiment. Show it:
Fig. 1 einen Längsschnitt durch ein als Absperr¬ ventil ausgestaltetes Heizungsventil mit einer vorgegebenen Voreinstellung1 shows a longitudinal section through a heating valve designed as a shut-off valve with a predetermined presetting
undand
Fig. 2 die Kombination eines Heizungsventiles gemäß Figur 1 mit einem an der Ventilspin¬ del aufgesetzten Membranregler.2 shows the combination of a heating valve according to FIG. 1 with a membrane regulator attached to the valve spindle.
Zunächst wird auf Figur 1 Bezug genommen. Mit der Ziffer 1 ist das Gehäuse eines Heizungsventiles bezeich¬ net. An diesem Gehäuse 1 sind sich gegenüberliegend die Anschlußstutzen 11 und 12 angedeutet, die zum Strang bzw. zum Heizkörper führen. Der Schraubstutzen 13 dient der Aufnahme des eingeschraubten Ventilober¬ teiles 2. Im Inneren des Gehäuses 1 ist ein Ventil¬ sitz 14 ausgebildet, gegen den ein erstes an der Ventilspindel 3 angeordnetes Verschlußstück 4 wirkt. Im Prinzip bestimmt die Stellung dieses ersten Ver- schlußstückes 4 zum entsprechenden Ventilsitz 14 die Voreinstellung für den Durchfluß. Mit diesem ersten Verschlußstück 4 ist das Heizungsventil absperrbar. In dem axialen Hohlraum 31 der Ventilspindel 3 ist gegen den Druck der Feder 6 ein doppelt wirkendes zweites Verschlußstück 5 verschiebbar. Mit seinem oberen Ver¬ schlußstückende 51 bildet es mit dem Ventilsitz 33 in in der hohlen Spindel 3 das Entleerungsventil. Durch Aufsetzen einer nicht dargestellten Entleerungsvorrich¬ tung ist das zweite Verschlußstück 5 mit seinem Ver¬ schlußstückende 51 von diesem Ventilsitz 31 abhebbar. Zur Entleerung strömt das Wasser aus dem Strang oder dem Heizkörper durch das hohle zweite Verschlußstück 5 in den Hohlraum 31 der Ventilspindel und von dort nach außen in die aufgesetzte Entleervorrichtung. Der Hohlraum 53 im zweiten Verschlußstück 5 ist zum Gehäuse hin offen. Er endet unterhalb des Verschlußstückendes 51, so daß im in Figur 1 gezeigten Zustand der Ventil¬ sitz 33 verschlossen ist.Reference is first made to FIG. 1. The number 1 denotes the housing of a heating valve. On this housing 1, the connecting pieces 11 and 12 are indicated opposite, which lead to the strand or to the radiator. The screw socket 13 serves to receive the screwed-in valve upper part 2. A valve seat 14 is formed in the interior of the housing 1, against which a first closure piece 4 arranged on the valve spindle 3 acts. In principle, the position of this first closure piece 4 relative to the corresponding valve seat 14 determines the presetting for the flow. With this first closure piece 4, the heating valve can be shut off. In the axial cavity 31 of the valve spindle 3, a double-acting second closure piece 5 can be displaced against the pressure of the spring 6. With its upper closure end 51 it forms with the valve seat 33 in the drain valve in the hollow spindle 3. By placing an emptying device, not shown, the second closure piece 5 with its closure piece end 51 can be lifted off this valve seat 31. For emptying, the water flows from the strand or the heater through the hollow second closure piece 5 into the cavity 31 of the valve spindle and from there to the outside into the attached emptying device. The cavity 53 in the second closure piece 5 is open to the housing. It ends below the closure piece end 51, so that the valve seat 33 is closed in the state shown in FIG.
Das gegenüberliegende Verschlußstückende 52 ragt durch das erste Ventilverschlußstück 4 nach außen hindurch und bildet mit dem hindurchragenden Abschnitt die Kontur des ersten Verschlußstückes und bestimmt mit diesem den Drosselspalt. An dem aus dem VentiloberteilThe opposite closure piece end 52 protrudes through the first valve closure piece 4 and forms with the protruding section the contour of the first closure piece and determines the throttle gap with it. At the top of the valve
2 herausrageπden Ende der Ventilspindel 3 ist auf einer Drehmitnahme 32 eine Schraubkappe 8 drehfest auf¬ gesetzt und durch eine darüber fest aufgesetzte Kappe 82 gesichert, die gleichzeitig die hohle Ventilspindel2 protrudes the end of the valve spindle 3, a screw cap 8 is placed on a rotary driver 32 in a rotationally fixed manner and secured by a cap 82 firmly placed thereon, which at the same time holds the hollow valve spindle

Die Voreinstellung erfolgt nach Abnahme der Kappe 82 und der Schraubkappe 8. Dabei wird die Ventilspindel 3 nicht bewegt. Danach erfolgt eine entsprechende Verdre¬ hung des Anzeigeringes 7, über den eine verzahnt im Anzeigering 7 sitzende Voreinstellmutter 10 mit dem darin drehfest aufgenommenen Stellring 10a verschoben wird und die Ventilspindel 3 in axialer Richtung mit¬ nimmt. Der entsprechenden Drehmitnahmeverbindung dient der Abschnitt 21 im Ventiloberteil 2 in Verbindung mit der entsprechenden Ausbildung der Ventilspindel 3 in diesem Bereich. Außen ist an dem Ventiloberteil 2 ein Gewindeabschnitt 22 ausgebildet, in den der Anzeigering 7 e i ngre i ft .The presetting is carried out after removing the cap 82 and the screw cap 8. The valve spindle 3 is not moved. This is followed by a corresponding rotation of the indicator ring 7, by means of which a presetting nut 10, which is toothed in the indicator ring 7, is displaced with the adjusting ring 10a accommodated therein in a rotationally fixed manner and drives the valve spindle 3 in the axial direction. The corresponding rotary driving connection is used in section 21 in the valve upper part 2 in connection with the corresponding design of the valve spindle 3 in this area. On the outside of the valve upper part 2, a threaded section 22 is formed, into which the indicator ring 7 entries.
Wie Figur 2 zeigt, ist auf das äußere Ende der Ventilspindel 3 mit einem entsprechend ausgebildeten Abschnitt 34, der auch der Aufnahme der Kappe 82 dient, ein Regler, vorzugsweise ein Membranregler 9, aufsetzbar. Seine zugehörige Schraubhülse 91 ragt dabei in einen Absatz 81 an der Schraubkappe 8 ein. Am Regelglied, im Falle des Membranreglers die Mem- bran, ist ein Betätiguπgsgl ied 92 in Form eines Rohres befestigt, welches in die hohle Ventilspindel 3 hineinragt und mit seinem freien Ende gegen das zweite Verschlußstück 5 wirkt. Über dieses Betäti¬ gungsglied wird das zweite Verschlußstück 5 mit seinem Verschlußstückende 52 in Richtung auf den Ven¬ tilsitz 14 im Gehäuse 1 verschoben und steuert damit geregelt den Durchfluß. As FIG. 2 shows, a regulator, preferably a diaphragm regulator 9, can be placed on the outer end of the valve spindle 3 with a correspondingly designed section 34, which also serves to receive the cap 82. Its associated screw sleeve 91 protrudes into a shoulder 81 on the screw cap 8. On the control element, in the case of the membrane regulator the membrane, an actuation element 92 in the form of a tube is fastened, which projects into the hollow valve spindle 3 and acts with its free end against the second closure piece 5. Via this actuator, the second closure piece 5 is displaced with its closure piece end 52 in the direction of the valve seat 14 in the housing 1 and thus controls the flow in a controlled manner.
