Definitions
- the present invention relates to a regulating and shut-off valve according to the preamble of claim 1, as for example from the DE-U-200 01 883 is known.
- Such a fitting has a valve housing in which a valve plug is displaceably guided and sealingly engageable with a valve seat formed on the valve housing.
- the regulating and shut-off valve has a valve outlet housing, into which a valve top is screwed with a rotatably arranged in this and connected to a rotary handle spindle.
- an intermediate tube is provided whose length is dimensioned such that the valve housing in the interior of a building and the valve outlet housing, the outer wall of the building can be arranged outstanding.
- the intermediate tube surrounds an intermediate spindle, which engages with the spindle, so that an axial displacement of the intermediate spindle takes place by rotation on the rotary handle, which is transmitted to the valve cone, which is in operative connection with the intermediate spindle.
- the previously known regulating and shut-off valve on a vent valve which has a valve with an open poppet occluding a venting sealing element which releases the vent opening with the valve plug closed.
- a venting valve body provided under spring preload on the valve outlet housing is provided. This is spring biased so that when acting in the valve outlet housing internal pressure, which also acts on the vent valve body, the vent valve is closed, whereas with shut off valve and running water from the valve, the vent valve opens at low internal pressure to one between the intermediate spindle and vent the intermediate space formed between the upper valve part and the valve cone when the shut-off valve is shut off, ie, the valve cone sealingly abuts against the valve seat.
- the control of the vent valve is not always reliable. Thus, it may happen that a hose is connected to an outlet of the valve outlet housing, which can be closed at the end, before the regulating and shut-off valve closed becomes. In this case, the internal water pressure in the valve outlet housing is not degraded, so that the vent valve is not actuated and a ventilation of the valve can not be performed thereafter. In frost, the valve can be blown up.
- the US 4,475,570 discloses an outlet fitting with forced ventilation.
- the previously known outlet fitting has a valve seat housing in which a valve plug is displaceably guided and can be applied sealingly against a valve seat formed on the valve seat housing. Furthermore, a valve outlet housing is provided. Between this valve outlet housing and the valve seat housing is an intermediate tube. Furthermore, the previously known outlet fitting to a valve. This is located in the outlet housing and regulates the flow passage to a hose nozzle. In the usual water extraction, this valve is deformed by the water pressure so that water flow is possible.
- the threaded engagement for mediating an axial movement by the rotational movement of the spindle takes place in the outlet housing after the US 4,475,570 via the valve seat housing, which is bridged for the flow of water by a recessed inside a threaded sleeve flow passage.
- the design according to this prior art requires a very accurate dimensional coordination between the actuator body and the position of the pin with respect to a sealing contact with the valve seat.
- the present invention is based on the problem, the regulating and Absperrara-matur of the type mentioned in such a way that a reliable venting of the valve can take place independently of the internal pressure in the valve outlet housing.
- the present invention is further based on the problem of improving the above-mentioned regulating and shut-off valve in terms of their durability.
- the present invention provides a regulating and shut-off valve having the features of claim 1.
- the regulating and shut-off valve according to claim 1 has an actuating body, which cooperates with the spindle and is held longitudinally displaceable in the valve upper part.
- the adjusting body is rotationally held in the valve bonnet.
- the actuator is inventively designed so that it is closed when the valve cone, i. can be moved longitudinally displaceable with a closed valve from a first position to a second position and in this case acts on the sealing element of the venting valve, that this closes the vent in the first position of the actuating body and releases it in a second position of the actuating body.
- the actuator according to the present invention is rotationally held relative to the spindle, but cooperates with this, for example, such that the displacement movement of the actuator is at least partially coupled to a sliding movement of the spindle and / or the displacement movement of the actuator in the valve outlet housing of the rotation of the Spindle is influenced, in particular directly due to the pitch of the spindle in the longitudinal direction thereof is adjusted. This adjustment takes place in particular when the valve is closed.
- the actuator can be adjusted from the first to the second position. In the first position of the actuating body acts on the sealing element such that it closes the vent opening, whereas the sealing element in the second position of the actuating body releases the vent opening.

Abstract
Description
Die vorliegende Erfindung betrifft eine Regulier- und Absperrarmatur gemäß dem Oberbegriff von Anspruch 1, wie sie beispielsweise aus dem
Eine derartige Armatur hat ein Ventilgehäuse, in dem ein Ventilkegel verschieblich geführt und dichtend an einen an dem Ventilgehäuse ausgebildeten Ventilsitz zur Anlage bringbar ist. Ferner weist das Regulier- und Absperrventil ein Ventilauslaufgehäuse auf, in das ein Ventiloberteil mit einer drehbar in diesem angeordneten und mit einem Drehgriff verbundenen Spindel eingeschraubt ist. Zwischen dem Ventilgehäuse und dem Ventilauslassgehäuse ist ein Zwischenrohr vorgesehen, dessen Länge derart bemessen ist, dass das Ventilgehäuse im Innenbereich eines Gebäudes und das Ventilauslaufgehäuse die Außenwand des Gebäudes überragend angeordnet werden kann. Das Zwischenrohr umgibt eine Zwischenspindel, die mit der Spindel im Eingriff steht, so dass durch Drehen an dem Drehgriff eine axiale Verstellung der Zwischenspindel erfolgt, die auf den Ventilkegel übertragen wird, welcher in Wirkverbindung mit der Zwischenspindel steht. Ferner weist die vorbekannte Regulier- und Absperrarmatur ein Entlüftungsventil auf, das ein bei geöffnetem Ventilkegel eine Entlüftungsöffnung verschließendes Dichtelement hat, welches die Entlüftungsöffnung bei geschlossenem Ventilkegel freigibt.Such a fitting has a valve housing in which a valve plug is displaceably guided and sealingly engageable with a valve seat formed on the valve housing. Further, the regulating and shut-off valve has a valve outlet housing, into which a valve top is screwed with a rotatably arranged in this and connected to a rotary handle spindle. Between the valve housing and the Ventilauslassgehäuse an intermediate tube is provided whose length is dimensioned such that the valve housing in the interior of a building and the valve outlet housing, the outer wall of the building can be arranged outstanding. The intermediate tube surrounds an intermediate spindle, which engages with the spindle, so that an axial displacement of the intermediate spindle takes place by rotation on the rotary handle, which is transmitted to the valve cone, which is in operative connection with the intermediate spindle. Furthermore, the previously known regulating and shut-off valve on a vent valve, which has a valve with an open poppet occluding a venting sealing element which releases the vent opening with the valve plug closed.
Bei der vorbekannten Regulier- und Absperrarmatur ist ein unter Federvorspannung an dem Ventilauslaufgehäuse vorgesehener Entlüftungsventilkörper vorgesehen. Dieser ist derart federvorgespannt, dass bei einem in dem Ventilauslaufgehäuse wirkenden Innendruck, der auch auf den Entlüftungsventilkörper wirkt, das Entlüftungsventil geschlossen ist, wohingegen bei abgesperrter Armatur und ablaufendem Wasser aus der Armatur sich das Entlüftungsventil bei geringem Innendruck öffnet, um einen zwischen der Zwischenspindel und dem Zwischenrohr zwischen dem Ventiloberteil und dem Ventilkegel ausgebildeten Zwischenraum zu entlüften, wenn die Absperrarmatur abgesperrt ist, d.h. der Ventilkegel an dem Ventilsitz dichtend anliegt. Die Steuerung des Entlüftungsventils ist aber nicht immer zuverlässig. So kann es vorkommen, dass an einem Auslassstutzen des Ventilauslaufgehäuses ein Schlauch angeschlossen ist, welcher endseitig verschlossen werden kann, bevor die Regulier- und Absperrarmatur geschlossen wird. In diesem Fall wird der Wasserinnendruck in dem Ventilauslaufgehäuse nicht abgebaut, so dass das Entlüftungsventil nicht betätigt und eine Lüftung der Armatur danach nicht durchgeführt werden kann. Bei Frost kann die Armatur gesprengt werden.In the previously known regulating and shut-off valve, a venting valve body provided under spring preload on the valve outlet housing is provided. This is spring biased so that when acting in the valve outlet housing internal pressure, which also acts on the vent valve body, the vent valve is closed, whereas with shut off valve and running water from the valve, the vent valve opens at low internal pressure to one between the intermediate spindle and vent the intermediate space formed between the upper valve part and the valve cone when the shut-off valve is shut off, ie, the valve cone sealingly abuts against the valve seat. The control of the vent valve is not always reliable. Thus, it may happen that a hose is connected to an outlet of the valve outlet housing, which can be closed at the end, before the regulating and shut-off valve closed becomes. In this case, the internal water pressure in the valve outlet housing is not degraded, so that the vent valve is not actuated and a ventilation of the valve can not be performed thereafter. In frost, the valve can be blown up.
Darüber hinaus besteht bei Regulier- und Absperrarmaturen das Problem, dass aufgrund des Nachlaufens von Wasser aus der Armatur bei der Belüftung der Benutzer der Armatur in dem Glauben, der Ventilkegel sei noch nicht zur Anlage an den Ventilsitz gelangt, den Drehgriff weiter dreht, was zu einer übermäßigen Beanspruchung des Ventilkegels bzw. des Ventilsitzes führt.In addition, there is the problem with regulating and shut-off valves, that due to the running of water from the valve during ventilation of the user of the valve in the belief that the valve plug is not yet comes to rest against the valve seat, the rotary handle continues to rotate, which an excessive stress on the valve cone and the valve seat leads.
Die
Der Gewindeeingriff zur Vermittlung einer axialen Bewegung durch die Drehbewegung der Spindel erfolgt bei dem Auslaufgehäuse nach der
Der vorliegenden Erfindung liegt das Problem zugrunde, die Regulier- und Absperrara-matur der eingangs genannten Art dahingehend weiterzubilden, dass eine zuverlässige Entlüftung der Armatur unabhängig von dem Innendruck in dem Ventilauslaufgehäuse stattfinden kann. Der vorliegenden Erfindung liegt weiterhin das Problem zugrunde, die eingangs genannte Regulier- und Absperrarmatur hinsichtlich ihrer Haltbarkeit zu verbessern.The present invention is based on the problem, the regulating and Absperrara-matur of the type mentioned in such a way that a reliable venting of the valve can take place independently of the internal pressure in the valve outlet housing. The present invention is further based on the problem of improving the above-mentioned regulating and shut-off valve in terms of their durability.
Zur Lösung dieser Probleme wird mit der vorliegenden Erfindung eine Regulier- und Absperrarmatur mit den Merkmalen von Anspruch 1 angegeben. Die Regulier - und Absperrarmatur nach Anspruch 1 weist einen Stellkörper auf, der mit der Spindel zusammenwirkt und längsverschieblich in dem Ventiloberteil gehalten ist. Darüber hinaus ist der Stellkörper verdrehfest in dem Ventiloberteil gehalten. Der Stellkörper ist erfindungsgemäß derart ausgestaltet, dass er bei geschlossenem Ventilkegel, d.h. bei geschlossener Armatur von einer ersten Stellung in eine zweite Stellung längsverschieblich bewegt werden kann und hierbei derart auf das Dichtelement des Entlüftungsventils einwirkt, dass dieses in der ersten Stellung des Stellkörpers die Entlüftungsöffnung verschließt und in einer zweiten Stellung des Stellkörpers diese freigibt.To solve these problems, the present invention provides a regulating and shut-off valve having the features of claim 1. The regulating and shut-off valve according to claim 1 has an actuating body, which cooperates with the spindle and is held longitudinally displaceable in the valve upper part. In addition, the adjusting body is rotationally held in the valve bonnet. The actuator is inventively designed so that it is closed when the valve cone, i. can be moved longitudinally displaceable with a closed valve from a first position to a second position and in this case acts on the sealing element of the venting valve, that this closes the vent in the first position of the actuating body and releases it in a second position of the actuating body.
Der Stellkörper nach der vorliegenden Erfindung ist verdrehfest gegenüber der Spindel gehalten, wirkt mit dieser jedoch zusammen, beispielsweise derart, dass die Verschiebebewegung des Stellkörpers zumindest abschnittsweise an eine Verschiebebewegung der Spindel gekoppelt ist und/oder die Verschiebebewegung des Stellkörpers in dem Ventilauslaufgehäuse von der Drehung der Spindel beeinflusst wird, insbesondere unmittelbar aufgrund der Gewindesteigung der Spindel in Längsrichtung derselben verstellt wird. Diese Verstellung erfolgt insbesondere bei geschlossenem Ventil. Bei geschlossenem Ventil kann der Stellkörper von der ersten in die zweite Stellung verstellt werden. Bei der ersten Stellung wirkt der Stellkörper derart auf das Dichtelement ein, dass dieses die Entlüftungsöffnung verschließt, wohingegen das Dichtelement in der zweiten Stellung des Stellkörpers die Entlüftungsöffnung freigibt.The actuator according to the present invention is rotationally held relative to the spindle, but cooperates with this, for example, such that the displacement movement of the actuator is at least partially coupled to a sliding movement of the spindle and / or the displacement movement of the actuator in the valve outlet housing of the rotation of the Spindle is influenced, in particular directly due to the pitch of the spindle in the longitudinal direction thereof is adjusted. This adjustment takes place in particular when the valve is closed. When the valve is closed, the actuator can be adjusted from the first to the second position. In the first position of the actuating body acts on the sealing element such that it closes the vent opening, whereas the sealing element in the second position of the actuating body releases the vent opening.

An den Spindelkopf 41a schließt sich ein Spindelbund 41b an. Unmittelbar benachbart zu dem Drehgriff 55 ist durch einen an der Spindel 41 befestigten Sprengring 41c eine ringförmige Anschlagfläche 41d ausgebildet.The
Zwischen einem sich zwischen dem Sprengring 41c und dem Spindelbund 41b erstreckenden zylindrischen Führungsabschnitt 41e der Spindel 41 und dem Ventiloberteil 42 befindet sich ein Führungshülsenabschnitt 43a einer Stellhülse 43. Diese erstreckt sich in axialer Länge über eine Teillänge des Ventiloberteils 42 und bis über den Endbereich der Zwischenspindel 63. An ihrem dem Führungshülsenabschnitt 43a gegenüberliegenden Ende bildet die Stellhülse 43 eine Zwischenspindelaufnahme 43b aus, an deren stirnseitigen Ende Dichtringe 43c vorgesehen sind, welche die Zwischenspindelaufnahme 43b gegenüber der Außenumfangsfläche der Zwischenspindel 63 abdichten.Between a
Die Zwischenspindelaufnahme 43b hat einen gegenüber dem Führungshülsenabschnitt 43a größeren Innendurchmesser und so ist zwischen den beiden Abschnitten 43a, 43b der Stellhülse 43 eine eine ringförmige Anlagefläche 43d für die Spindelschulter 41b ausbildende Stellhülsenschulter 43e vorgesehen.The
Die Außenumfangsfläche des Führungshülsenabschnitts 43a der Stellhülse 43 liegt an Dichtringen 42a dichtend an, die in dem Ventiloberteil 42 aufgenommen sind. Die Zwischenspindel 63 ist verdrehfest, jedoch axial verschieblich in der Zwischenspindelaufnahme 43b gehalten; die Stellhülse 43 wiederum ist mit ihrem Führungshülsenabschnitt 43a axial verschieblich, jedoch verdrehfest in dem Ventiloberteil 42 geführt.The outer peripheral surface of the guide sleeve portion 43 a of the adjusting

An der einen Seite dieses Anlagekranzes 42b liegt die Druckfeder 44 an. Die gegenüberliegende Seite des Anlagekranzes 42b bildet die Gegenfläche zu der an dem Sprengring 41c ausgebildeten Anschlagfläche 41d der Spindel 41.Against the free end-side end of the guide sleeve portion 43 a is a
Das Ventilauslaufgehäuse 4 weist an seiner Unterseite eine unter Zwischenlage eines Rohrbelüfters 45 angeschraubte Schlauchtülle 46 auf, die einen Auslasskanal 47 axial verlängert, welcher sich im Wesentlichen rechtwinklig zu der Längsachse der Zwischenspindel 43 bzw. der Spindel 41 erstreckt. Auf der anderen Seite des Ventilauslaufgehäuses 4 wird der Auslasskanal 47 in Form einer Entlüftungsbohrung fortgesetzt, in der ein eine Entlüftungsöffnung 48 freigebendes Entlüftungsventil 49 angeordnet ist. Dieses Entlüftungsventil 49 weist einen Entlüftungsventilkörper 49a auf, der unter Vorspannung einer Entlüftungsfeder 49b gegen eine Dichtfläche eines Entlüftungsventileinsatzes 49c unter Zwischenlage eines Dichtungselementes 49d die Entlüftungsöffnung 48 verlegend anliegt.

Wird nun von dem Benutzer der Armatur zur Entnahme von Wasser der Drehgriff 55 gedreht, so wird diese Drehung über die Spindel 41 übertragen, welche relativ zu der Zwischenspindel 63 wandert, die über eine Sechskantführung verdrehfest in der Stellhülse 43, diese wiederum über eine Sechskantführung verdrehfest in dem Ventiloberteil 42 aufgenommen ist. Zunächst aber bleibt die Armatur geschlossen, da die Relativbewegung zwischen der Spindel 41 und der Zwischenspindel 63 durch eine Axialbewegung der Stellhülse 43 zusammen mit der Spindel 41 ausgeglichen wird, und zwar aufgrund der Federkraft der Druckfeder 44. Diese Druckfeder 44 übt eine Federkraft aus, die größer als der gegen den Ventilkegel 22 wirkende Leitungsdruck des dort anstehenden Wassers ist. Die Drehung an dem Handgriff 55 führt dementsprechend zunächst zu einer Lageverschiebung der Stellhülse 43 gegenüber dem Ventiloberteil 42 und gegenüber der Zwischenspindel 63. Durch die Anlage der Spindelschulter 41b an der Stellhülsenschulter 43e wird diese Bewegung der Stellhülse 43 auf die Spindel 41 übertragen. Der Führungskegel 49e wandert hierbei über das Kurvenprofil 43f, d.h. über die Rampe auf das Plateau, wodurch das Dichtungselement 49d gegen die an dem Entlüftungsventilkörper 49a ausgebildete Dichtfläche gegen die Kraft der Feder 49b angelegt wird. Das Entlüftungsventil 49 wird somit geschlossen. Die vorerwähnte Relativbewegung von Stellhülse 43 und Spindel 41 endet, wenn der Sprengring 41c mit seiner Anschlagfläche 41d gegen den Anlagekranz 42b des Ventiloberteils 42 zur Anlage gelangt, so dass die Stellhülse 43 gegenüber dem Ventiloberteil 42 lagegesichert ist. Danach führt eine weitere Drehung an dem Handgriff 55 zu einer Relativbewegung zwischen der Zwischenspindel 63 und der Stellhülse 43 in axialer Richtung, die in ihrer Lage unverändert bleibt und somit das Entlüftungsventil 49 geschlossen hält.If now turned by the user of the valve for removing water, the
