Description
Bei Hochdruck-Ventilen besteht die Gefahr, idaß beim Öffnen des Ventils durch Weiterdrehen der Spindel über die Endstellung hinaus Ader Schraubteil, in dem die Spindel geführt ist, herausgedreht wird und. dann infolge des -hohen: Druckes mit Spindel und Ventilteller ,herausgeschleudert- wird und dabei, :auch (den das Ventil Bedienenden ernsthaft gefährdet.In the case of high-pressure valves, there is a risk that the valve will open by turning the spindle further beyond the end position, the screw part, in which the spindle is guided, is unscrewed and. then as a result of the high pressure with spindle and valve plate, is thrown out- and at the same time,: also (which the Valve operators at serious risk.
Erfindungsgemäß wird dies dadurch verhütet, daiß eine an ,ihrem einen Ende :am Ventilgehäuse befestigt und mit :ihrem anderen Ende mit Vorspannung um .den Schraubteil herumgelegt ist, derart, daß sie beim Hereinschrauben des Schraub.teiiles gelockert, beim Herausschrauben dagegen giespannt wird, sich dabei. fest an den Schraubteil anlegt und eine Festkupplung des Schraubteiles mit dem Ventilgehäuse heristellt.According to the invention this is prevented by giving one to her End: attached to the valve body and with: its other end preloaded around .the screw part is wrapped around in such a way that when the screw part is screwed in loosened, but when unscrewing it is poured, thereby. firmly to the Screw part applies and a tight coupling of the screw part with the valve housing manufactures.
Die Sicherung bietet ,gegenüber den üblichen Sicherungen den Vorteil, -daß sie (beim Aus- und Einbau des Schrau'bteiles nicht :gelöst oder ehtfernt zu werden braucht, wobei: es bisher oft vergessen wurde, idäe Sicherung wieder in ihren Betriebszulstand z,u bringen.The fuse offers the advantage over the usual fuses, -that they (when removing and installing the screw part) not: loosened or removed needs, whereby: it has been often forgotten so far, idäe fuse back in their Bring operating permit z, u.
Gegenüber einer anderen bekannten Sicherung der Spfndelführung gegen Herausdrehen, bei: der ein Anschlag .am Ventilkegel brei voll ,,geöffnetem Ventil gegen das Ventilgehäuse zu liegen :kommt, .hat die Sicherung naich dler Erfindung den Vorteil, daß sie ohne genaue ,und kostspielige Paßaebeit auch nachträglich angebracht werden kann, daß sie leicht zu montieren ist und ferner ihre Wirksamkeit jederzeit von außen überprüft werden kann.Compared to another known backup of the spindle guide against Unscrew when: the one stop on the valve cone is almost full, the valve is open to lie against the valve housing: comes, .has the fuse after the invention the advantage that they can also be retrofitted without an exact and costly passport can be that it is easy to assemble and also its effectiveness at all times can be checked from the outside.
Inder Zeichnung ist ein Ausführungsbe.iispiel der Erfindung in Anwendung auf ein Hochdruck-Ventil dargestel!l,t.In the drawing, an exemplary embodiment of the invention is in use shown on a high pressure valve! l, t.
Auf den Gewindeteil 6 des Ventilgehäuses i ist der als Führung für die Ventilspindel 2 und in.bekannter Weise als Spannvorrichtung für die Stopfbuchsenpackung dienende Schraubteil aufgeschraubt, der aus dem Ventilführungsteil 3, dem Sechskant 4 und einem sich hieran ansetzenden Teil 5 mit glatter Oberfläche besteht. Um den Ansatz 5 ist der obere Teil einer Schraubenfeder 7 mit Vorspannung herumgelegt. Das untere Ende der Schraubenfeder ist hakenförmig umgebogen und in einer Bohrung 8 des Ventilgehäuses eingehakt. Statt dessen kann naturgemäß auch eine andere Befestigung dieses Schraubenfederendes vorgesehen sein, beispielsweise mittels einer öse am Ventilgehäuse.On the threaded part 6 of the valve housing i is used as a guide for the valve spindle 2 and in a known manner as a clamping device for the gland packing Serving screw part screwed on from the valve guide part 3, the hexagon 4 and an attached part 5 with a smooth surface. To the Approach 5, the upper part of a helical spring 7 is wrapped around with bias. The lower end of the helical spring is bent over like a hook and in a hole 8 of the valve body hooked. Instead, a different fastening can of course also be used this coil spring end be provided, for example by means of an eyelet on Valve body.
Die Schraubenfeder 7 'ist mit solcher Vorspannung auf dem Ansatz 5 angebracht und !besitzt eine Steigung in :solcher Ridhtu:ng, d.aß sie -sich beim Hereinschrauben des Schraubteiles lockert, .so daß also ohne an dem Zustand der Sicherung etwas zu ändern, der Schraubteil heneingedreht und damit in :die Stop@fbuchsenpackung nachgezogen werden kann. Wenn dagegen beim 'Öffnen ides Ventils @die Spindel :auch nach Erreichen der Endstellung des Ventils weiter in der gleichen Richtung gedreht wird, dann wird der Schraubteil zwar zunächst mitgenommen und um ein kurzes ,Stück herausgedreht. Jedoch wird. hierbei rdie Schraubenfeder 7 gespannt, so daß. sie sich ;nun ,sehr feist :gegen den Ansatz 5 ;legt, such festzieht und dabei eine Festkupplung.zwitAchen dem Ansatz 5 und idem Ventilgehäuse i bildet, in dem oie mit ihrem Ende 8 verankert ist. Ein weiteres Herausdrehen des Schraubtei'les ist @damlit unmöglich gemacht.. Wenn der Schrauib@tei1 zur Reparatur od. dgl: aus dem Ventilgehäuse i durch Umdrehen des Sechskants .4 entfernt wenden soll, -ist zunächst das hakenfärm-ige umgebogene Ende der Schraubenfeder 7 auszuhaken.The helical spring 7 'is on the extension 5 with such a pretension attached and! has a slope in: such Ridhtu: ng, i.e. that it -she -she Screwing in the screw loosens, so that without affecting the state of the To change the fuse a little, screw in the screw part and thus into: the stopper socket packing can be tightened. If, on the other hand, when opening the valve @ the spindle: also after reaching the end position of the valve continued to rotate in the same direction is, then the screw part is initially taken along and a short distance unscrewed. However, will. here rdie coil spring 7 tensioned so that. she yourself; well, very fat: against approach 5; set, seek tight and thereby a tight coupling the approach 5 and idem valve housing i forms in which oie anchored at its end 8 is. A further unscrewing of the screw part is @damlit made impossible .. When the Schrauib @ tei1 for repair or the like: from the valve housing i by turning it around of the hexagon .4 is to be removed, -is first the hook-shaped bent Unhook the end of the coil spring 7.
