Vorrichtung zum Vorpressen von DichtungselementenDevice for pre-pressing sealing elements

Die Erfindung betrifft eine Vorrichtung zum Vorpressen von Dichtungselementen insbesondere von Stopfbuchspackungen aus geflochtenen Garnen von Absperr- und Regelarmaturen sowie von Pumpenwellen.The invention relates to a device for pre-pressing sealing elements, in particular stuffing box packings made of braided yarns of shut-off and control valves as well as of pump shafts.

In der Praxis hat es sich gezeigt, daß die in die Stopfbuchse eingelegten Packungsringe durch die Stopfbuchsbrille häufig sehr unterschiedlich gepreßt werden. Dabei werden die im Stopfbuchsgrund liegenden Packungsringe zu wenig gepreßt. Korrosionsablagerungen am Innenmantel der Stopfbuchse verstärken dabei noch diesen Effekt. Dies hat den Nachteil, daß nur ein Teil der Pakkungsringe an der Dichtarbeit beteiligt ist. Die Folge davon ist, daß die dichtenden Packungsringe schneller verschlissen werden und somit die Stopfbuchsbrille häufiger nachgezogen werden muß. Ein Einlaufen der Ventilspindel im dichtenden Bereich kann ebenfalls als Folge davon gesehen werden.In practice, it has been shown that the packing rings inserted into the stuffing box are often pressed very differently by the stuffing box gland. The packing rings located in the bottom of the stuffing box are not pressed enough. Corrosion deposits on the inner surface of the stuffing box reinforce this effect. This has the disadvantage that only some of the packing rings are involved in the sealing work. The result of this is that the sealing packing rings wear out more quickly and the stuffing box gland has to be tightened more often. A running-in of the valve spindle in the sealing area can also be seen as a result of this.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der es auf einfache Weise möglich ist, die Pakkungsringe so zu montieren, daß sie gleichmäßiger an der Dichtarbeit beteiligt sind.The invention is based on the object of creating a device with which it is possible in a simple manner to mount the packing rings in such a way that they participate more evenly in the sealing work.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß jeder eingelegte Packungsring mit einer Montagebuchse vorgepreßt werden kann.The solution to this problem by the invention is characterized in that each inserted packing ring can be pre-pressed with a mounting bushing.

Die Neuerung wird nachfolgend anhand eines in der Zeichung dargestellten Ausführungsbeispiels näher beschrieben. In der Zeichnung zeigen:The innovation is described in more detail below using an example shown in the drawing. The drawing shows:

Fig. 1 einen Halbschnitt durch die in eine Stopfbuchse eingebrachte MontagebuchseFig. 1 a half-section through the mounting bushing inserted into a stuffing box

Fig. 2 Montagebuchse mit AusziehwerkzeugFig. 2 Mounting bush with extraction tool

Fig. 3 Montagebuchse mit Ausziehwerkzeug in SeitenansichtFig. 3 Mounting bush with extraction tool in side view

In der Figur 1 ist die zweigeteilte Montagebuchse 1 in eine Stopfbuchse eingelegt. Jeweils nach dem Einlegen eines Pakkungsringes wird durch die zweigeteilte Montagebuchse die gesamte Packung und insbesondere der zuletzt eingelegte Pakkungsring vorgepreßt. Die Vorpreßkraft wird durch die Stehbolzen auf die Stopfbuchsbrille 2 und damit auf die Montagebuchse 1 übertragen. Können die nachfolgend eingelegten Packungsringe bereits durch die Stopfbuchsbrille vorgepreßt werden, wird ohne Montagebuchse weitergearbeitet.In Figure 1, the two-part assembly bushing 1 is inserted into a stuffing box. After each packing ring is inserted, the entire packing and in particular the last inserted packing ring is pre-pressed through the two-part assembly bushing. The pre-pressing force is transferred through the stud bolts to the stuffing box flange 2 and thus to the assembly bushing 1. If the packing rings inserted subsequently can already be pre-pressed through the stuffing box flange, work continues without the assembly bushing.

In der Figur 2 ist die neuerungsgemäße Montagebuchse 1 mit dazugehörigem Ausziehwerkzeug 3 dargestellt. Das Ausziehwerkzeug besteht aus einer Halbschale mit einen Zughaken, welcher in das Gegenstück der Montagebuchse eingreift. Das halbschalenförmige Ausziehwerkzeug 3 besitzt einen Haltegriff zu herausziehen.Figure 2 shows the new assembly bushing 1 with the associated extraction tool 3. The extraction tool consists of a half-shell with a pull hook, which engages in the counterpart of the assembly bushing. The half-shell-shaped extraction tool 3 has a handle for pulling it out.
