Description

Die Erfindung betrifft eine federnd angepreßte Stopfbuchsenabdichtung, insbesondere für Spindeln von Absperrventilen.The invention relates to a resiliently pressed gland seal, especially for spindles of shut-off valves.

Es ist bereits bekannt, die Stopfbüchse von Sp.indelabdchtungen @durch eine Schraubenfeder anzupressen. Die Schraubenfeder umgibt dabei die Spindel und biegt entweder innerhalb oder außer-:halb des Gehäuses und des von der Flüssigkeit benetzten Raumes. Bei einer Ausführung ,ist sie in, der Stopfbüchse selbst untergebracht, in jedem Fall hat sie eine gewisse axiale Ausdehnung und trägt damit zu .den Überallesabmessungen .der Dichtung bei, was besonders bei Absperrorganen unerwünscht ,ist. Bei der Spindelabdichtung nach der Erfindung ruht die Stopfbuchspackung auf einer mit dem Rand im Gehäuse eingelagerten, als Tellerfeder wirkenden Scheibe. Die Schraubenfeder kann dann entfallen, eine Auflagerscheibe muß ohnehin vorgesehen werden. Die Packung wird dadlüreh sehr viel kürzer.It is already known that the stuffing box from Sp.indelabdchtungen @ by to press a coil spring. The coil spring surrounds the spindle and bends either inside or outside of the housing and of the liquid wetted space. In one version, it is housed in, the stuffing box itself, in any case, it has a certain axial extent and thus contributes to the overall dimensions .The seal, which is particularly undesirable for shut-off devices. With the spindle seal According to the invention, the gland packing rests on one with the edge in the housing embedded disc acting as a disc spring. The coil spring can then be omitted a support washer must be provided anyway. The pack will be very good much shorter.

Man .hat Tellerfedern schon verwendet, um ein Hahnküken oder einen 'Ventilkegel gut dichtend auf .den Sitz zu drücken. Um einen gleichmäßigen Druck auf Stopfbuchsp.aekungen zu erzielen, sind; Tellerfedern aber noch nicht verwendet worden.Disc springs have already been used to seal a cock plug or a '' Press the valve cone onto the seat with a good seal. To ensure even pressure to be achieved on the stuffing box; Disc springs but not yet used been.

In drer Zeichnung ist ein Absperrventil .mit einer Stopfbuchsenabdicbtung nach der Erfindung dargestellt. Das Gehäuse i wird. durch das Oberteil :2 ge- 3o schlossen. Das dargestellte Ventil .besitzt eine nichtsteigende Spindel 3 mit dem Ventilteller 4. Auf einem Absatz ,im Gehäuse i liegt die Scheibe 5 mit ihrem Rand. Die Stopfbuchspackung 6 ruht auf der Scheibe 5, sie wird,durch.die Stopfbüchse 7 35 zusammengedrückt.In the drawing is a shut-off valve with a stuffing box seal shown according to the invention. The housing i will. through the top: 2 ge 3o closed. The valve shown .besitzt a non-rising spindle 3 with the Valve disk 4. The edge of the disk 5 lies on a shoulder in the housing i. The stuffing box packing 6 rests on the washer 5, it is through.the stuffing box 7 35 compressed.

Die Zeichnung gibt die Anwendung ,der Stopfbüchsabdichtung bei einer bestimmten Ausführung des Absperrventils wieder. Die Erfindlung kann ,ohne wesentliche Änderung auf andere Ven- 40 ti.le übertragen werden. Sie ist auch anwendbar bei Ventilen mit steigender Spindel.The drawing shows the application of the stuffing box seal in a specific design of the shut-off valve again. The invention can be without essential Change can be transferred to other valves. It is also applicable to Valves with a rising stem.
