Stopfbuchsabdichtung Ton Absperrschiebern mit BundBpindel"Stuffing box seal clay gate valves with collar and spindle "

TJm eine einwandfreie Abdichtung der Stopfbuchse "bei Abeperrorganen su erzielen, muß die gebräuchliche Stopfbuchspackung, ■welche im allgemeinen aus geflochtener Hanf«- oder AsbeBtschnur besteht, mittels einer Stofpbuchsbrille oder eines besonderen Druckstückes Btark zusammengepresst werden. Die Polge davon ist, daß die Spindel sich nur sehr schwer drehen läßt, da die Reibung zwischen Packung und Spindeloberfläche durch den großen pressdruck stark erhöht wird. Bei Schiebern, die entweder ganz offen oder ganz geschlossen sind, ißt es nur nötig, daß die Stopfbuchsenin ösr\ ETitiffteiinn&en-elnwandfrei dicht sind. Während der kurzzeitigen Dauer der Betätigung kommt es auf eine absolute Dichtheit nicht an. Aus diesem Grunde werden häufig Tor dem Bewegen der Spindel die Stopfbuchsschrauben etwas gelöst, um eine leichtere Bedienung zu erzielen. Wenn der Schieber in der Endstillung ist," werden die Stopfbuchsschrauben wieder nachgezogen und damit die Stopfbuchse abgedichtet. Dies ist_aber bei ,Schiebern, die unter der Erde oder an sonst irgendwie unzulänglichen Stellen eingebaut sind, nicht möglich^ Es sind Sehieberausführungen bekannt, bei denen durch den gegen die Haube anlaufenden Zeil ein Druckstock die Packung von Schieber inneren her zusammenpresst, um auf diese Weise ein Abdichten der Spindel bei ganz geöffnetem Schieber zu erzielen. Dies hat jedoch den Nachteil, daß die Packung bei geschlossenem Schieber nicht unterIn order to achieve a perfect sealing of the stuffing box in blocking devices, the usual stuffing box packing, which generally consists of braided hemp or asbestos cord, must be pressed together by means of a stuffing box gland or a special pressure piece can be very difficult to turn, because the friction between the packing and the spindle surface is greatly increased by the large contact pressure. For valves that are either fully open or fully closed, it eats only necessary that the Stopfbuchsenin ETR \ ETitiffteiinn & en-elnwandfrei are tight. While The short duration of the actuation does not depend on absolute tightness. For this reason, the stuffing box screws are often loosened a little before moving the spindle in order to achieve easier operation and thus the stuffing box sealed. But this is not possible with valves that are installed underground or in any other inadequate places ^ There are known valve designs in which a pressure block compresses the packing from the inside of the valve in this way by means of the line running against the hood to achieve sealing of the spindle with the slide fully open. However, this has the disadvantage that the pack is not under when the slide is closed

Druck steht, so daß sie in dieser Stellung undicht werden kann·Pressure is so that they are leaking in this position can·

Um diesen Mangel zu "beseitigen, wird gemäß der !feuerung vorgeschlagen, die Spindel selbst zum Anpressen der Packung heranzuziehen· Die bei den Endstellungen dee Abeperrkörpere auftretende Eeaktionskraft sucht die Spindel mit ihrem Bund nach außen "bzw. nach dem Schie"berinneren zu "bewegen. Dabei wird jeweils eine der Packungen, die über und unter dem Spindelbund liegen, zusammengepreßt. Durch mehr oder weniger starkes Anziehen der Spindel ist es möglich, die Anpresskraft derart zu steigern, daß eine einwandfreie Abdichtung erzielt wird. Bei der Betätigung cLes Schiebers dagegen wird Bofort die Packung entlastet, so daß die Spindel leicht „bewegt werden kann. Weitere Eigenheiten ergeben sich aus der nachfolgenden Besehreibung und den am Schluß aufgeführten Ansprüche*In order to remedy this deficiency, it is proposed according to the fire to use the spindle itself to press the packing tries to move the spindle with its collar outwards or "inwards" after the slide. One of the Packs lying above and below the spindle collar, compressed. By tightening the spindle to a greater or lesser extent, it is possible to increase the contact pressure in such a way that a perfect sealing is achieved. When pressing cLes Slide, however, Bofort is relieved of the packing, so that the Spindle can be easily "moved. Further peculiarities result from the following description and those listed at the end Expectations*

Die Schieberhau.be 1 besitzt oberhalb des Spindeldurchlassee 2 eine Aussparung, welche genügend lang ist, um ober- und unterhalb des Bundes 3 der ^Spindel 4 $e eine Dichtungspackung 5, 6 aufzunehmen.

"DeT äußere Spindeldurchlaß ist alB Stopfbuchsbrille 9 ausgeführt, durch welche in üblicher Weise mittels der Schraube 10, 11 der Anpreßdruck der Packungen 5, 6 geregelt wird.
