Description

Es sind schlauchförmige, elastische Spindeldichtungen. für Ventile bekannt, welche im Schließzustand des Ventils gestreckt und im öffnuilgszustand des Ventils entspannt sind.They are tubular, elastic spindle seals. for valves known which stretched in the closed state of the valve and in the open state of the valve are relaxed.

Da aber z. B. Auslaufventile fast dauernd geschlossen und nur in den kurzen Öffnungsperioden geöffnet werden, ist es von wesentlicher Bedeutung, die Dehnungsbeanspruchung des die Spindel abdichtenden Dichtkörpers auf den Öffnungsvorgang zu verlegen. Deshalb wird erfindungsgemäß die Dichtung .derart angeordnet, daß sie während des Öffnungsvorganges axial gestreckt wird und im Schließzustand des Ventils entspannt ist.But since z. B. outlet valves closed almost continuously and only in the short opening periods, it is essential that the Expansion stress of the sealing body sealing the spindle on the opening process relocate. Therefore, according to the invention, the seal is arranged in such a way that it is stretched axially during the opening process and when the valve is closed is relaxed.

Dazu kann der Durchstromkanal gleichachsig, auch winklig oder in verschiedener Höhe zweinander in den Dichtkörperraum einmünden.For this purpose, the flow channel can be coaxial, also angled or in different Height between each other open into the sealing body space.

In der Zeichnung ist ein Ventil nach der Erfindung beispielsweise im Längsschnitt dargestellt. Dias VentiIgehäuseunterteil a ist mit einem Oberteil b verschraubt, in welch letzterem eine Schraubspindel c ,geführt ist, welche in an sich bekannter Art drehgelenkig mit einer Unterspindel d zusammenarbeitet. Eine elastische schlauchförmige Dichtung g ist mit einem Außenflansch lt innerhalb des Unterteiles durch eine Buchse i während der Verschraubung von a mit b fest eingepreßt und mit einem Innenflansch an seiner anderen Seite vermittels einer Muttere mit der Unterspindeld dicht verspannt, wobei eine Unterlagscheibe r eine Verdrehung der Buchse und des Dichtkörpers verhindert. Zwischen der Buchse i und der Dichtung o, ist ein Rohrabschnitt-o und zwischen letzterer und der Unterspindel t1 ebenfalls ein solcher Rohrabschnitt p eingebaut zur Sicherung der beiden Flansche gegen deren radiale Verschiebung. Der Innenflansch der Dichtung ist mit f und der Außenflansch derselben mit lt bezeichnet.In the drawing, a valve according to the invention is shown, for example, in longitudinal section. The lower part of the valve housing a is screwed to an upper part b, in which the latter a screw spindle c is guided, which works in a manner known per se pivotably with a lower spindle d. An elastic tubular seal g is firmly pressed in with an outer flange lt inside the lower part through a socket i during the screwing of a with b and tightly clamped with an inner flange on its other side by means of a nut with the lower spindle, whereby a washer r rotates the Bushing and the sealing body prevented. Between the bushing i and the seal o, a pipe section -o is installed, and between the latter and the lower spindle t1 there is also such a pipe section p installed to secure the two flanges against their radial displacement. The inner flange of the seal is designated by f and the outer flange of the same by lt.
