Das dargestellte Niederschraubventii mit längsfedernder Verbindung zwischen Ventilteller und Spindel erhalt beim Oeffnen und Schliefsen des Ventils eine reibende Drehung des Tellers auf seinem Site, so dafs der Teller einerseits sich frei in die zum gehörigen Schliefsen geeignete Stellung betten kann und andererseits durch abschleifende Reibung seinen guten Schlufs selbsttätig sicherstellt. Sehr zweckmäfsig wird dabei die Spindei mittelst einer Kegeldichtung abgedichtet.The Niederraubventii shown with a longitudinal spring connection between the valve plate and the spindle receives a frictional rotation when the valve is opened and closed of the plate on its site, so that on the one hand the plate can be freely inserted into the one belonging to it Can bedding a suitable position and on the other hand by abrasive friction automatically ensures good conclusions. The spindle is very useful sealed with a cone seal.
Die mittelst Griffes α und Schraubengewindes im Gehäuse H verstellbare Spindel b ist am unteren Ende mit einer Bohrung c versehen, in deren senkrechten Schlitzen i der aus einer dicken, flachen Metallscheibe bestehende Ventilteller g mittelst durchgeschraubten Stiftes h geführt ist. Zwischen Ventilteller und Boden der Bohrung ist eine federnde Packung j eingespannt, bestehend aus einer Anzahl schwach ausgebauchter und auf einander gebauter Metallscheiben. Die unterste der Scheiben ist in der Mitte ausgebuckelt, so dafs sie möglichst in der Mittelrichtung gegen den Ventilteller wirkt. Die 'Schlitze i sind so lang, dafs der Teller g im offenen Zustande etwas aus der Bohrung c vorgetreten ist und beim Niederschrauben der Spindel etwas in jene zurückweichen kann, dagegen nur so breit, dafs der Teller sich sowohl beim Oeffnen wie beim Schliefsen mit dem Schlüssel drehen und also reibend auf seinem Sitz gleiten mufs. Der Anschlag k verhindert ein zu weites Lüften des Ventils. The spindle b , adjustable by means of the handle α and screw thread in the housing H, is provided at the lower end with a bore c, in the vertical slots i of which the valve plate g, which consists of a thick, flat metal disk, is guided by means of a screwed through pin h. A resilient packing j , consisting of a number of slightly bulged metal disks built on one another, is clamped between the valve plate and the bottom of the bore. The lowermost of the disks is bulged in the middle so that it acts against the valve disk in the central direction as far as possible. The slots i are so long that the plate g protrudes somewhat out of the hole c when it is open and can recede a little into it when the spindle is screwed down, but only so wide that the plate is both open and closed with the Turn the key and slide it on its seat by rubbing. The stop k prevents the valve from being released too far.
Bei Röhren von gröfserer Weite würde die Anordnung nach Fig. 1 eine Spindel b von unbequem grofsem Durchmesser erfordern, deshalb wird in solchem Falle besser die: Abänderung Fig. 3 angewendet. Hier ist' die Spindel m in einem auf die oben offene Ventilkammer aufgeschraubten Deckel m1 geführt und endet oben in ein schwach verjüngtes Vierkant, auf welches der Griff η gesteckt und mittelst Stiftes ο befestigt wird.In the case of tubes of greater width, the arrangement according to FIG. 1 would require a spindle b of an uncomfortably large diameter, so in such a case it is better to use the modification of FIG. 3. Here the spindle m is guided in a cover m 1 screwed onto the valve chamber, which is open at the top, and ends at the top in a slightly tapered square, onto which the handle η is inserted and fastened by means of a pin ο.
In Fig. 4 ist eine Kegeldichtung für die Ventilspindel angeordnet. Die Dichtung besteht aus dem metallenen Kegel p, welcher oben den Spindelgriff q trägt und von der Plattenfeder * gegen seinen Sitz im Deckel r gehalten wird, während sein unteres Ende eine Aussparung hat, in welche ein an der Spindel b fester Vorsprung u fafst und bei der Drehung der Schraube eindringt. Der Deckel r fafst mit einer ringförmigen Kante in eine ringförmige Nuth im Oberrande des Gehäuses H und ist dort mit einer geeigneten Packung versehen.In Fig. 4, a cone seal for the valve spindle is arranged. The seal consists of the metal cone p, which carries the spindle handle q at the top and is held against its seat in the cover r by the plate spring *, while its lower end has a recess into which a projection u fixed to the spindle b fafs and at the rotation of the screw penetrates. The lid r fits with an annular edge into an annular groove in the upper edge of the housing H and is provided there with a suitable packing.
Anstatt die Verbindung zwischen Spindel und Teller durch federnde Scheiben j herzustellen, kann man sich zu demselben Zwecke auch anders gestalteter Federn oder anderer elastichen Zwischenmittel bedienen.Instead of establishing the connection between the spindle and the plate by resilient disks j , differently designed springs or other elastic intermediate means can be used for the same purpose.
