Description
Ventil, insbesondere Atemventil für Atemschutzgeräte Die Erfindung betrifft ein Ventil, insbesondere ein Atemventil für Atemschutzgeräte, bei dem über einen hohlen, am einen Ende offenen, am anderen Ende geschlossenen und auf dem Mantel mit Durchtrittsöffnungen versehenen Ventilkörper ein Verschlußkörper aus Gummi gespannt ist.Valve, in particular breathing valve for breathing apparatus The invention relates to a valve, in particular a breathing valve for breathing apparatus, in which over a hollow one, open at one end, closed at the other end and on the mantle with passage openings provided valve body stretched a closure body made of rubber is.
Bei einem bekannten, für die Förderung von Flüssigkeiten bestimmten Ventil dieser Art ist über einen kegeligen Ventilkörper, dessen Mantelfläche Längsöffnungen aufweist, ein entsprechend geformter G»mR"ikegel gezogen und an der unteren, größeren Öffnung durch eine Verscbraubung festgespannt. Der Durchtritt der Flüssigkeit durch das Ventil erfolgt in der Weise, daß der Gummikegel durch den Flüssigkeitsdruck geweitet wird, wodurch die Flüssigkeit am oberen Ende ausströmen kann. Infolge des hierbei entstehenden großen Widerstandes ist ein solches Ventil für Atemgeräte nicht verwendbar.In the case of a known one, intended for the delivery of liquids Valve of this type is a conical valve body, the outer surface of which has longitudinal openings has, a correspondingly shaped G »mR" ikegel drawn and attached to the lower, larger Opening clamped by a screw connection. The passage of the liquid through the valve is made in such a way that the rubber cone is affected by the fluid pressure is widened, whereby the liquid can flow out at the upper end. As a result of the Such a valve for breathing apparatus is not the result of great resistance usable.
Demgegenüber besteht die Erfindung darin, daß der Verschlußkörper in unter Eigenspannung stehende Lappen unterteilt ist, die die Ventilöffnungen des nach dem geschlossenen Ende des vorzugsweise zylindrischen Ventilkörpers zu liegenden, in eine Mehrzahl von Ventilsitzflächen aufgeteilten Mantels überdecken. Die Ventilsitzflächen könnenentweder parallel zur Längsachse des Ventilkörpers verlaufen, oder aber das Profil kann die Form einer nach oben bzw. nach unten abgestumpften Pyramide haben, so daß die Profilflächen in einem schrägen Winkel zur Längsachse des Hohlkörpers stehen. Die letztere Ausführungsform bietet den Vorteil, daß in den geneigten Profilflächen die Durchlaßöffnungen größer als in den planparallelen Flächen gemacht werden können. Der Ventilkörper besitzt an .der übergangsstelle von dem runden Teil in den Ventilsitzflächenteil des Ventilkörpers eine Nut und eine Wulst, die zur Halterung des wulstförmig ausgebildeteten geschlossenen Randes des Verschlußkörpers dienen.In contrast, the invention consists in that the closure body is subdivided into lobes under internal tension, which open the valve openings of the to be located after the closed end of the preferably cylindrical valve body, cover jacket divided into a plurality of valve seat surfaces. The valve seat surfaces can either run parallel to the longitudinal axis of the valve body, or that Profile can have the shape of a truncated pyramid upwards or downwards, so that the profile surfaces are at an oblique angle to the longitudinal axis of the hollow body stand. The latter embodiment has the advantage that in the inclined profile surfaces the passage openings can be made larger than in the plane-parallel surfaces. The valve body has the transition point from the round part to the valve seat surface part of the valve body has a groove and a bead, which are designed to hold the bead-shaped serve closed edge of the closure body.
Das erfindungsgemäße Ventil hat den Vorteil, daß es billig herzustellen, einfach zu warten ist, wenig Raum einnimmt und deshalb leicht in jede genügend weite Rohrleitung eingebaut werden kann.The valve according to the invention has the advantage that it is cheap to manufacture, is easy to maintain, takes up little space and is therefore easy enough to move into each one Pipeline can be installed.
In der Zeichnung ist der Erfindungsgegenstand dargestellt.The subject of the invention is shown in the drawing.
Hierin ist i der an seinem einen Ende offene, zweckmäßig zylindrisch geformte Ventilkörper, der sich nach dem anderen verschlossenen Ende zu vorteilhaft etwas verjüngt und am äußeren Umfang in ein vielflächiges, in der Zeichnung achtflächig dargestelltes Profi12 übergeht. Als Werkstoff für den Ventilkörper z wird vorzugsweise eine Preßmasse aus Kunstharz verwendet. Die Flächen 3 des Profils 2 können entweder parallel zur Längsachse des Ventilkörpers i verlaufen, oder sie können auch geneigt zu dieser stehen. Mit q. sind die Ventilöffnungen bezeichnet. 5 ist eine über den Ventilkörper i gespannte Manschette, deren die Ventilöffnungen q. überdeckender Teil in .unter Eigenspannung stehende Lappen 7 unterteilt ist; die Eigenspannung kann durch entsprechende Formgebung oder durch leicht federnde Einlagen erreicht werden. Mit ihrem nicht unterteilten Rande legt sich die Manschette 5 in eine Ringnut 8 des Ventilkörpers i, hinter der noch eine Wulst 6 angeordnet ist, so daß ein sicherer Halt der Manschette erreicht wird.Herein i is the one that is open at one end and is expediently cylindrical molded valve bodies, which closed one after the other The end is tapered a little bit to advantage and on the outer circumference into a multi-faceted, in Profi12, which is represented by eight faces in the drawing, passes over. As a material for the Valve body z is preferably a molding compound made of synthetic resin. The surfaces 3 of the profile 2 can either run parallel to the longitudinal axis of the valve body i, or they can be inclined to it. With q. the valve openings are marked. 5 is a cuff stretched over the valve body i, of which the valve openings q. The covering part is divided into flaps 7 under residual stress; the internal stress can be achieved by appropriate shaping or by slightly resilient Deposits can be achieved. With its edge that is not subdivided, the cuff lies down 5 in an annular groove 8 of the valve body i, behind which a bead 6 is arranged is, so that a secure hold of the cuff is achieved.
