Abstract

The valve is especially a mixing valve, and has a rotary slider (14) which is arranged in a housing (26), and which is connected to a motor or manual drive (38). The slider can be coupled to the drive by a tongue (22), which is sealed in the housing, and which has a detachable connection to the slider. The tongue may be connected to the slider using spigots (28) and recesses (20,30), and may have bores (20) in order for the fluid which is to be controlled, to be guided above and below the slider. The latter may be symmetrical about a plane which is normal to its axis (16) of rotation.

Description

Die vorliegende Erfindung bezieht sich auf ein Ventil nach dem Gattungsbegriff des Patentanspruches 1.The present invention relates to a valve according to the generic term of Claim 1.

Derartige Ventile besitzen einen Drehschieber, der im Falle eines Durchgangsventiles den Durchtritt des Mediums zwischen einem Ein- und Ausgang steuert und im Falle eines Mischventils über einen zusätzlichen Eingang noch eine Beimischung gestattet. Der Drehschieber besteht in bekannter Weise aus einem mit einer entsprechenden Steuerkurve versehenen Steuerküken, und er wird durch einen Motor- und/oder Handantrieb über eine entsprechende Steuerwelle, die abgedichtet im Ventilgehäuse gelagert ist, angetrieben. Als nachteilig hat sich hierbei herausgestellt, daß das Steuerküken nur von einer Seite von dem Druck des zu steuernden Fluids beaufschlagt wird, wodurch das zu einer Drehung erforderliche Drehmoment erhöht wird.Such valves have a rotary valve, which in the case of a two-way valve Controls the passage of the medium between an input and output and in the case of one Mixing valve allows an admixture via an additional input. Of the Rotary vane consists in a known manner of one with a corresponding control curve provided control plug, and it is powered by a motor and / or manual drive corresponding control shaft, which is sealed in the valve housing, driven. As disadvantageously, it has been found that the control plug only from one side of the Pressure is applied to the fluid to be controlled, causing rotation required torque is increased.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Ventil der eingangs genannten Art so auszubilden, daß sein Drehschieber druckausgeglichen ist und somit mit geringem Drehmoment bewegt werden kann.It is therefore the object of the present invention to provide a valve of the type mentioned to be designed so that its rotary valve is pressure balanced and thus with little Torque can be moved.

Die Lösung dieser Aufgabe gelingt gemäß den kennzeichnenden Merkmalen des Patentanspruches 1. Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Ventils sind den abhängigen Ansprüchen entnehmbar.This problem is solved in accordance with the characteristic features of Claim 1. Further advantageous refinements of the valve according to the invention can be found in the dependent claims.

Anhand der einzigen Figur der beiliegenden Zeichnung sei im folgenden das erfindungsgemäße Ventil näher beschrieben. Gemäß dieser einzigen Figur weist das Ventil 10 ein Gehäuse 12 auf, in welchem ein Drehschieber 14 um eine vertikale Achse 16 drehbar gelagert ist und über seine Steuerkurve 18 den Durchgang eines Fluids zwischen einem nicht dargestellten Ein- und Ausgang, die beide senkrecht zur Zeichenebene verlaufen bzw. die Beimischung des Fluids über den dargestellten Eingang steuert. The valve according to the invention is described in more detail below with reference to the single figure of the accompanying drawing. According to this single figure, the valve 10 has a housing 12 in which a rotary slide valve 14 is rotatably mounted about a vertical axis 16 and, via its control cam 18, the passage of a fluid between an inlet and outlet, not shown, both of which run perpendicular to the plane of the drawing or controls the admixture of the fluid via the input shown.

Der Drehschieber 14 ist im Bereich der Steuerkurve 18 mit parallel zur Drehachse 16 verlaufenden Bohrungen 30 versehen, die das Fluid unter und über den Drehschieber 14 führen.The rotary valve 14 is provided in the area of the control cam 18 with bores 30 running parallel to the axis of rotation 16 , which guide the fluid below and above the rotary valve 14 .

Ein Mitnehmer 22 ist über eine O-Ringdichtung 24 in einem Oberteil 26 des Ventilgehäuses abgedichtet und drehbar gelagert. Der Mitnehmer 22 greift mit Zapfen 28 in entsprechende Ausnehmungen 30 in dem Drehschieber 14 bzw. in die Bohrungen 20 des Drehschiebers 14 ein. Der Drehschieber 44 ist vorzugsweise aus Messing hergestellt, und der Mitnehmer 22 besteht vorzugsweise aus Kunststoff.A driver 22 is sealed via an O-ring seal 24 in an upper part 26 of the valve housing and is rotatably mounted. The driver 22 engages with pins 28 in corresponding recesses 30 in the rotary valve 14 or in the bores 20 of the rotary valve 14 . The rotary valve 44 is preferably made of brass, and the driver 22 is preferably made of plastic.

Eine Antriebswelle 32 ist an ihrem unteren Ende mit einem Vierkant 34 versehen, mit der sie in eine entsprechende Ausnehmung 36 in dem Mitnehmer 22 eingreift.A drive shaft 32 is provided at its lower end with a square 34 , with which it engages in a corresponding recess 36 in the driver 22 .

Ein Antrieb 38 für den Drehschieber 14 ist mittels einer Befestigungsschraube 40 mit dem Oberteil 26 des Gehäuses befestigt, wobei das Oberteil 26 in nicht näher dargestellter Weise mit dem Ventilgehäuse 12 verbunden ist.A drive 38 for the rotary valve 14 is fixed by means of a fastening screw 40 to the upper part 26 of the housing, wherein the upper part 26 is connected in a manner not shown with the valve housing 12th

Der Antrieb 38 umfaßt einen Motorantrieb, der aus einem Synchronmotor 42 besteht, welcher über ein Zahnrädergetriebe 44 auf die Antriebswelle 32 drehend einwirkt.The drive 38 comprises a motor drive, which consists of a synchronous motor 42 , which acts on the drive shaft 32 in a rotating manner via a gear transmission 44 .

Ferner ist ein Handrad 46 mit der Antriebswelle 32 verbunden, und das Handrad 46 kann gegen die Kraft einer Feder 48 zusammen mit der Antriebswelle 32 axial verschoben werden, wobei der Vierkant 34 mit dem Zahnrädergetriebe 44 außer Eingriff gelangt und nur noch mit der Vierkant-Ausnehmung 36 in dem Mitnehmer 22 zusammenwirkt, so daß der Handantrieb unabhängig von dem Motorantrieb wirksam ist.Furthermore, a handwheel 46 is connected to the drive shaft 32 , and the handwheel 46 can be axially displaced together with the drive shaft 32 against the force of a spring 48 , the square 34 disengaging from the gear transmission 44 and only with the square recess 36 cooperates in the driver 22 so that the manual drive is effective independently of the motor drive.

Durch die lose Verbindung des Mitnehmers 22 mit dem Drehschieber 14 und die Abdichtung des Mitnehmers 22 im Gehäuse ist der Drehschieber 14 von oben und unten durch den Druck des Fluids beaufschlagt und sozusagen schwimmend gelagert, so daß er mit geringer Reibung und kleinem Drehmoment bewegt werden kann.Due to the loose connection of the driver 22 with the rotary valve 14 and the sealing of the driver 22 in the housing, the rotary valve 14 is acted upon from above and below by the pressure of the fluid and is floating, so to speak, so that it can be moved with little friction and low torque .

Der Drehschieber 14 ist vorzugsweise zu einer zur Drehachse 16 senkrecht verlaufenden Ebene symmetrisch ausgebildet, so daß die von oben und unten einwirkenden Kräfte des Fluids gleich groß sind.The rotary slide valve 14 is preferably symmetrical with respect to a plane perpendicular to the axis of rotation 16 , so that the forces of the fluid acting from above and below are equal.
