Belüftungsventil Ventilation of the area sventil

In Luftschutzräumen und ähnlichen aus einer mehr oder weniger großen Anzahl von Räumen bestehenden Anlagen, die be- oder entlüftet werden müssen, werden Ventile verwendet, um die Belüftung bzw. Entlüftung der einzelnen Räume zu regulieren. Diese Ventile sind in das Rohrsystem zum Transport^ In air raid shelters and the like from one more or less large number of rooms existing systems that need to be ventilated, valves are used to to regulate the ventilation or venting of the individual rooms. These valves are in the pipe system for transport ^

der Luft eingebaut und bestehen bisher meistens aus Klappen ' oder sonstigen Absperrorganen, die als selbständige Bauelemente ausgebildet sind.built into the air and so far mostly consisted of flaps' or other shut-off devices that are designed as independent components.

Die Neuerung hat das Ziel, diese Ventile einmal zu vereinfachen und zu verbilligen und auch in ihrer Wirkungsweise zu verbessern. Demgemäß besteht die Neuerung- darin, daß das aus einem geeigneten Kunststoff bestehende Belüftungsventil nach Art einer von.einem Flansch begrenzten Reinigungsöffnung des betreffenden Rohres ausgebildet ist, die durch einen rostartigen Deckel verschlossen ist, dessen Spalten durch ein verschiebliches Gegenstück mehr oder weniger verschlossen werden können. Das Ventil kann nach'der Neuerung entweder in die Mantelfläche des Be- oder EntlUftungsrohres eingeordnet sein. Eine weitere Möglichkeit "Gesteht aber auch darin, das Ventil dem Rohr 'als stirnseitige Abschlußkappe zuzuordnen. Die Neuerung hat weiter zum Gegenstand, daß die öffnung des Ventils von einem Maschengewebe überdeckt- ist. Es hat sich gezeigt, daß diese Maßnahme vorteilhaft ist, da mit ihr einmal verhindert wird, daß Fremdkörper von außen in das Ventil bzw, in das Rohr einge-·.· bracht werden können, wie z. B. brennende Tabakreste, wodurch Gerüche in andere Kb ;me übertragen werden können. Andererseits wird durch das Maschengewebe die Geräuschübertragung verringert, da es sich als schallhernrnend erwiesen hat.The aim of the innovation is to simplify and make these valves cheaper and also to improve their mode of operation. Accordingly, the innovation consists in the fact that the ventilation valve made of a suitable plastic is designed in the manner of a cleaning opening of the pipe in question limited by a flange, which is closed by a grate-like cover, the gaps of which can be more or less closed by a sliding counterpart . According to the innovation, the valve can either be arranged in the jacket surface of the ventilation pipe. Another possibility, however, is to assign the valve to the pipe as an end cap. Another object of the innovation is that the opening of the valve is covered by a mesh fabric. It has been shown that this measure is advantageous because is prevented with it once that foreign bodies or from the outside into the valve, einge- in the pipe · · can be introduced, such as burning tobacco residues, whereby odors in other Kb;.. me can be transmitted the other hand, by the. Mesh fabric reduces the transmission of noise because it has been shown to be acoustically absorbent.

Claims

In the drawing, an embodiment of the innovation is shown. Fig. 1 shows a plan view of the ventilation pipe 1 with the valve 2. Fig. 2 shows a section according to II-II of Fig. 1. Fig. J shows the view of a construction designed as an end cap. The tube 1 has an opening formed in the manner of a cleaning opening, delimited by a flange 3, which is closed by the cover which is adapted to the shape of the tube and which is fastened to the tube with two screws 5. Inside the cover see the correspondingly slotted counterpart 6, which can be moved with the help of the screws 7 in the circumferential direction so that the slots of the cover 4 and counterpart 6 more or less overlap. Any position between the full opening of the slots and their full closure can therefore be set. In principle, the valve shown in Fig. 3 is designed in the same way. The cover 8 with the radial slots closes the tube. The counterpart "below" with the corresponding slots ~ can be moved around the axis 10 with the aid of the pin 11 'in the Urafang direction for the purpose of changing the free passage cross-section.
