Description
Bekanntlich verunglücken alljährlich viele Arbeiter infolge mangelhafter Gasabsperrvorrichtungen an Gasvergiftung.It is well known that many workers have accidents every year as a result of inadequate gas shut-off devices from gas poisoning.
Gewöhnliche Gasschieber, die ja an sich bei großen Abmessungen infolge Verziehens der Dichtungsflächen nicht dicht bleiben, lassen sich bei staubigen Gasen (Rohgasleitungen) nicht verwenden, da sich bei geöffnetem Schieber die Schieberführungen voll Staub setzen und der Schieber dann nicht geschlossen werden kann.Ordinary throttle valves, which are inherent in large dimensions as a result of distortion of the Sealing surfaces do not remain tight, can be used with dusty gases (raw gas lines) Do not use, as the slide guides will become full of dust when the slide is open and then the slide cannot be closed.
' Man verwendet daher meist Durchzugschieber, Steckscheiben und Brillen, die beim
Wechseln einen großen Querschnitt freigeben, durch die das Gas ins Freie strömt und die
Bedienungsmannschaft gefährdet. In geschlossenen Räumen sind daher derartige Vorrichtungen
überhaupt nicht verwendbar.
Dicht sind eigentlich von den bisher bekannten Absperrvorrichtungen nur die Wasserverschlüsse.
Da sie aber bei dem großen Durchmesser der Gasleitungen viel Raum erfordern,
einen mindestens einmaligen Richtungswechsel und damit eine Drosselung der'For this reason, pull-through valves, blanking disks and glasses are usually used which, when changing, reveal a large cross-section through which the gas flows into the open and endangers the operating team. Such devices cannot therefore be used at all in closed rooms.
Of the previously known shut-off devices, only the water closures are actually tight. But since they require a lot of space with the large diameter of the gas lines, an at least one change of direction and thus a throttling of the
Gase bedingen, ida ferner das erforderliche' Reinhalten der Wassertassen eine ständige und unangenehme Arbeit erfordert und schließlich wegen der Gefahr, daß bei plötzlichen Drucksteigerungen das Absperrwasser herausgeschleudert wird, eine zweite feste, wenn auch nicht ganz dichte Absperrvorrichtung erforderlich erscheint, werden sie nur sehr selten angewendet.Gases make it necessary to keep the water cups clean at all times and requires unpleasant work and finally because of the risk of sudden Pressure increases the shut-off water is thrown out, a second fixed, if not completely tight shut-off device appears necessary, they are used very rarely.
Die Erfindung ist geeignet, die eingangs erwähnten Übelstände und Gefahren zu beseitigen, weil sie einfach, überall anwendbar ist und selbst bei den schmutzigsten Gasen oder Flüssigkeiten einen stets vollkommen dichten Abschluß gewährleistet.The invention is suitable for eliminating the abuses and dangers mentioned at the beginning, because it is easy to use everywhere and even with the dirtiest gases or Liquids always guaranteed a completely tight seal.
In der Zeichnung sind zwei Ausführüngsformen der Erfindung schematisch dargestellt.In the drawing, two embodiments of the invention are shown schematically.
In Fig. ι ist das Schiebergehäuse A auf den beiden Rohrenden B und B1 verschiebbar angeordnet. Die Zeichnung zeigt den Schieber im geöffneten Zustand; die beiden Dichtungsringe C und C1 sind gegeneinander abgedichtet, bleiben daher sauber und verhindern ein Eindringen des Staubes in das Schiebergehäuse. In Fig. Ι the valve housing A is arranged on the two pipe ends B and B 1 displaceably. The drawing shows the slide in the open state; the two sealing rings C and C 1 are sealed against each other, so they remain clean and prevent dust from entering the valve body.
Will man den Schieber schließen, so wird das Gehäuse mittels der-ringsherum angeordneten Schrauben D so weit vom Rohrende B abgezogen, daß die Schieberplatte E herabgelassen werden kann. Dann wird das Gehäuse wieder nach der anderen Richtung verschoben, bis die Dichtungsringe C und C1 an beiden Seiten der Schieberplatte ringsherum fest anliegen und einen dichten Abschluß bewerkstelligen. If you want to close the slide, the housing is pulled off the pipe end B by means of the screws D arranged around it so that the slide plate E can be lowered. Then the housing is shifted again in the other direction until the sealing rings C and C 1 rest firmly all around on both sides of the slide plate and achieve a tight seal.
In Fig. 2 sitzt die Dichtung C1 fest im Gehäuse A1 während die Dichtung C in einem beweglichen Ringe B befestigt ist. Dieser Ring ist durch die beiden elastischen Stahlblechringe E und E1 dicht, aber beweglich mit dem Gehäuse verbunden. An zwei oder drei Stellen des Ringes kqnnen die in der Zeichnung angedeuteten Zugstangen F angebracht werden, die mit Hilfe einer geeigneten Vorrichtung ein rasches Öffnen und Schließen des Ringes und damit des Schiebers ermöglichenIn Fig. 2 the seal C 1 sits firmly in the housing A 1 while the seal C is fixed in a movable ring B. This ring is tightly but movably connected to the housing by the two elastic sheet steel rings E and E 1. The tie rods F indicated in the drawing can be attached to two or three places on the ring, which, with the aid of a suitable device, enable the ring and thus the slide to be opened and closed quickly
sollen. Bei offenem Schieber brauchen die Dichtungen nur mit dieser Einrichtung gegeneinander gedichtet zu werden, da ja kein Druck zu überwinden ist und der Verschluß nur staub-, nicht aber gasdicht sein muß. Die Druckschrauben D sollen nur bei geschlossenem Schieber einen ringsherum vollkommen dichten Abschluß bewirken.should. When the slide is open, the seals only need to be sealed against one another with this device, since no pressure has to be overcome and the closure only has to be dust-tight, but not gas-tight. The pressure screws D should only produce a completely tight seal all around when the slide is closed.
Ob zwar nun dadurch, daß die Dichtungsflächen stets sauber bleiben und die Dichtung ringsherum fest angedrückt wird, ein dichter Abschluß bewirkt wird, läßt sich durch weitere Maßnahmen vollkommene Sicherheit herstellen. Zunächst wird bei geschlossenem Schieber die Entlüftungsöffnung G geöffnet. Etwa noch durchdringendes Gas gelangt ins Freie, aber mangels eines Überdruckes nicht in den abgesperrten Teil der Leitung.Whether a tight seal is brought about by the fact that the sealing surfaces always remain clean and the seal is pressed tightly all around, complete security can be established by further measures. First of all, the vent opening G is opened when the slide is closed. Any gas that may still penetrate enters the open air, but, in the absence of excess pressure, does not enter the shut-off part of the line.
Wenn nun noch Wasser in -das Schieber-If there is still water in -the slide-
ao gehäuse geleitet wird, können etwaige Gasblasen emporsteigen, nie aber in den abgesperrten Teil der Leitung gelangen.ao housing is passed, any gas bubbles can rise, but never into the locked one Get part of the line.
In geschlossenen Räumen muß man die Entlüftungsöffnungen durch eine Leitung ins Freie führen.In closed rooms you have to insert the ventilation openings through a pipe Free lead.
Auf diese Weise werden in einfachster Art die Vorteile des Wasserverschlusses mit einer festen, stets zuverlässigen Absperrvorrichtung verbunden, ohne die Nachteile beider Arten von Verschlüssen aufzuweisen.In this way, the advantages of the water seal with a fixed, always reliable shut-off device, without the disadvantages of both To have types of closures.
