Description
DEUTSCHESGERMAN
Die Erfindung betrifft ein Ventil aus einem Kunststoff, der sich leicht im Spritzverfahren verarbeiten läßt, wie es z. B. bei den Polyamiden der Fall ist. Ein Auslaufventil dieser Art, bei dem das Verschlußstück durch einen Seesterngriff gegen die Strömungsrichtung auf seinen Sitz geschraubt werden kann, ist bekannt. Das Ventil arbeitet ohne besondere Abdichtung des Gewindes zwischen dem aufschraubbaren Seesterngriff und dem Gehäusestutzen; infolgedessen läßt es sich nicht vermeiden, daß bei einem offenen Ventil und starkem Zuflußdruck Wasser an dem Gewinde austritt.The invention relates to a valve made of a plastic that is easy to process by injection molding lets how it z. B. is the case with polyamides. An outlet valve of this type, in which the closure piece can be screwed onto its seat by a starfish handle against the direction of flow, is known. The valve works without any special sealing of the thread between the screw-on starfish handle and the housing socket; consequently it cannot be avoided that with an open Valve and strong inflow pressure water emerges from the thread.
Bei dem erfindungsgemäßen Ventil wird dies vermieden, und zwar in vorteilhafter Weise dadurch, daß am Ventilstößel eine Manschette angegossen ist, die vom Wasser gegen die Innenwand des Gehäuses gedrückt wird. Dadurch wird ohne besondere Stopfbüchse oder sonstige Spindelabdichtung die Fuge zwischen dem beweglichen Teil und dem Gehäuse abgedichtet; das Ventil kann infolgedessen audh in Fällen verwendet werden, in denen im Auslauf Überdruck gegen die freie Atmosphäre herrscht.In the valve according to the invention, this is avoided, in an advantageous manner in that a sleeve is cast on the valve tappet, which is pressed against the inner wall of the housing by the water will. This creates the joint without a special stuffing box or other spindle seal sealed between the moving part and the housing; as a result, the valve can also be used in Cases are used in which there is overpressure against the free atmosphere in the outlet.
In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen, im Spritzverfahren hergestellten Absperrventils im Längsschnitt dargestellt.In the drawing is an embodiment of an inventive, manufactured by injection molding Shut-off valve shown in longitudinal section.
Es besteht aus einem aus spritzbarem Kunststoff hergestellten Gehäuse 1 mit dem Ventilsitz 3.It consists of a housing 1 made of injectable plastic with the valve seat 3.
Stirnseitig trägt das Gehäuse 1 ein Steilgewinde 4, mit dem der Drehgriff 5 verschraubbar ist. Der Hub des Drehgriffes 5 ist in bekannter Weise durch eine Deckplatte 6 und eine Kopfschraube 7 begrenzt.On the front side, the housing 1 has a coarse thread 4 with which the rotary handle 5 can be screwed. The hub the rotary handle 5 is delimited in a known manner by a cover plate 6 and a head screw 7.
Das Ende des Gehäuses 1 trägt ein zur Aufnahme des Anschlußstutzens 8 dienendes Innengewinde 9.The end of the housing 1 has an internal thread 9 serving to accommodate the connecting piece 8.
Der Ventilstößel 10, welcher mit dem Kolbenteil 10a in dem Gehäuse 1 geführt ist, trägt die erfindungsgemäß
angespitzte, dünnwandige Manschette 11. Der Ventilkegel 2 arbeitet mit dem Ventilsitz 3 zusammen.
Wenn der Drehgriff 5 betätigt wird und durch Drehung nach rechts den Ventilkegel 2 von seinem
Ventil aus Kunststoff, der sich im
Spritzverfahren verarbeiten läßtThe valve tappet 10, which is guided with the piston part 10 a in the housing 1, carries the thin-walled sleeve 11, which is pointed according to the invention. The valve cone 2 works together with the valve seat 3. When the rotary handle 5 is operated and by turning to the right, the valve cone 2 of its plastic valve, which is located in the
Can be processed by spraying

Sitz 3 abgehoben hat, wird die Manschette 11 von der Flüssigkeit unter Druck gesetzt, wobei sie sich weitet und die vordere Gehäusekammer zum Hubgewinde hin abdichtet.Seat 3 has lifted, the cuff 11 is pressurized by the liquid, whereby it expands and seals the front housing chamber to the lifting thread.
Bei geschlossenem Ventil entspannt sich die Manschette 11 und tritt in die Anfangsstellung zurück.When the valve is closed, the cuff 11 relaxes and returns to the initial position.
