Description

  

      Ventil,        insbesondere        für        Mischbatterien       Die vorliegende Erfindung betrifft ein     Ventil,    ins  besondere für Mischbatterien, das gekennzeichnet ist  durch einen dem Abdichten des Ventils dienenden  O-Ring, sowie durch einen am     Ventilkörper    an  geordneten     Vorkopf,    welcher derart geformt ist, dass  die     Durchflussmenge    über den grösseren Teil des  Ventilhubes angenähert proportional dem Hub ist.  



  Ausführungsbeispiele des Erfindungsgegenstandes  werden anschliessend anhand der Zeichnung erläu  tert. Es zeigen in Ausschnitten:       Fig.    1     einen    Schnitt durch ein Ventil in geschlosse  ner Stellung mit kegelförmigem Sitz mit Abdichtungs  ring im Ventilkörper,       Fig.    2 ein Ventil in halb offener Stellung mit Ab  dichtungsring im Ventilsitz,       Fig.    3 einen Schnitt durch eine weitere Ausfüh  rungsform eines Ventils in geschlossener Stellung,       Fig.    4 ein Ventil analog     Fig.    2 mit Abdichtungs  ring im     Ventilsitz,

            Fig.5    einen Schnitt durch eine weitere Ausfüh  rungsform analog     Fig.    1,       Fig.    6 ein Ventil analog     Fig.    2.  



  Die in den Figuren dargestellten     Ventile    weisen  einen Ventilkörper 1 mit     kugelkalottenförmigem    Vor  kopf 1' auf, dessen Ventilsitz in einem Teil 3 an  geordnet ist. Der     Vorkopf    kann dabei auch anders  geformt sein, jedoch derart, dass die     Durchflussmenge     über den     grössern    Teil des Ventilhubes     ebenfalls    an  genähert proportional dem Hub ist.

   Als Dichtungs  organ dient ein O-Ring 2, welcher beim Kegelventil  nach     Fig.    1, beim Flachventil nach     Fig.    3 und beim  Ventil mit     kugelförmigem    Sitz nach     Fig.    5 im Ventil  körper, in den     Ausführungen    nach den     Fig.2,    4  und 6 im     Ventilsitz    3 angeordnet ist.

      Diese Konstruktion, bei welcher durch die Wir  kung des vorhandenen     Vorkopfes    1' eine sehr gute  und genaue Regulierung der     Durchflussmenge    erreicht  wird, erlaubt überdies mit kleinen Schliessdrücken das  Ventil absolut dicht und     rückschlagfrei        zu    schliessen.

    Die strömungstechnisch     vorteilhafte        Formgebung    spe  ziell der Ausführungen nach den     Fig.    1, 2, 5 und 6  erzielt eine Verminderung der Reibung und des       Durchflussgeräusches.       Die bis jetzt, besonders bei Mischbatterien und       Warmwasserventilen    so     unerwünschten        Quellungen     der Gummi und/oder     Kunststoffdichtungen,    mit einer       in    der Folge stark schwankenden Wassermenge, be  sonders des warmen Wassers,     sind    durch diese Kon  struktion praktisch behoben.  



  Ein Auswechseln des     O-Ringes    ist     denkbar    ein  fach. Er sitzt bei allen     Ausführungen    mit     etwas    Span       nung    in einer     schwalbenschwanzförmigen    Nut 4,       welche        den        Ring    2     in        der        Dicke        ungefähr        zu        85        %          aufnimmt    und umschliesst.

   Beim Schliessen des Ven  tils wird der O-Ring 2 leicht     zusammengedrückt.    Er  kann sich dabei innerhalb der Nut 4 ausdehnen.  



  Ein weiterer Vorteil dieser Anordnung liegt darin,  dass die Schliessbewegung des Ventils durch das Auf  liegen des metallenen Ventilkörpers auf dem me  tallenen Ventilsitz     begrenzt    wird, so dass der O -Ring  nur so weit durch Druck beansprucht werden     kann,     als dies durch die Tiefe der Nut und die Grösse des       O-Ringes        vorausbestimmt    ist.



      Valve, in particular for mixer taps The present invention relates to a valve, in particular for mixer taps, which is characterized by an O-ring serving to seal the valve, as well as by a head on the valve body, which is shaped in such a way that the flow rate over the larger part of the valve lift is approximately proportional to the lift.



  Embodiments of the subject matter of the invention are then tert erläu with reference to the drawing. It shows in excerpts: Fig. 1 is a section through a valve in closed position with a conical seat with sealing ring in the valve body, Fig. 2 is a valve in the half-open position with sealing ring from the valve seat, Fig. 3 is a section through a further embodiment Approximate shape of a valve in the closed position, Fig. 4 shows a valve analogous to Fig. 2 with a sealing ring in the valve seat,

            5 shows a section through a further embodiment analogous to FIG. 1, FIG. 6 shows a valve analogous to FIG. 2.



  The valves shown in the figures have a valve body 1 with a spherical cap-shaped front head 1 ', the valve seat of which is arranged in a part 3 on. The front head can also be shaped differently, but in such a way that the flow rate over the greater part of the valve stroke is also approximately proportional to the stroke.

   As a sealing organ, an O-ring 2 is used, which in the cone valve according to FIG. 1, the flat valve according to FIG. 3 and the valve with a spherical seat according to FIG. 5 in the valve body, in the embodiments according to FIGS. 2, 4 and 6 is arranged in the valve seat 3.

      This construction, in which a very good and precise regulation of the flow rate is achieved through the action of the existing front head 1 ', also allows the valve to be closed absolutely tightly and without kickback with small closing pressures.

    The aerodynamically advantageous shape especially of the embodiments according to FIGS. 1, 2, 5 and 6 achieves a reduction in friction and flow noise. Up to now, especially with faucets and hot water valves, so undesirable swelling of the rubber and / or plastic seals, with a consequent strongly fluctuating amount of water, especially the warm water, are practically eliminated by this construction.



  Replacing the O-ring is easy. In all versions, it sits with some tension in a dovetail-shaped groove 4, which takes up and encloses the ring 2 in thickness to approximately 85%.

   When closing the valve, the O-ring 2 is slightly compressed. It can expand within the groove 4.



  Another advantage of this arrangement is that the closing movement of the valve is limited by the metal valve body resting on the me-tallenen valve seat, so that the O -ring can only be subjected to pressure as far as the depth of the groove and the size of the O-ring is predetermined.
