Description
Prüfgerät zur Feststellung des Mitatmens von Gasschutzmasken Für .die Brauchbarkeit einer GaSS,ChutzTnaSke ist die Stärke des Mitatmens des Maskenkörpiers, insbesondere bei der Einahnung, von großer Bedeutung. Wenn schon bei flacher Atmung, .also bei geringem Einatemwiderstand, :der Maskenkörper so weit zusammenkllappit, daß,er beispielsweise die Nase berührt, so ist die Maske für den Dauergebrauch ungeeignet. je größer die Härte des Maskenstoffes und die. Verrippu ng des Maskenkörpers sind, um so wenigex atmet die Maske m it. Dagegen erhöht eine zü weiche Gummibeschaffenheit das Mitatmen der Maske.Test device to determine whether gas masks are breathing together For .the Usefulness of a GaSS, ChutzTnaSke is the strength of the breathing of the mask body, especially when anticipating, of great importance. If with shallow breathing, .so with low inhalation resistance: the mask body collapses so far, that, for example, he touches the nose, the mask is unsuitable for long-term use. the greater the hardness of the mask material and the. Are ribbing of the mask body, the mask breathes so few times with it. On the other hand, a too soft rubber texture increases the breathing of the mask.
Zur Bestimmung der Stärke des Mitatmens von Gasschutzmasken bzw. zur Feststellung, ob der Maskenkörper zu weich ist oder ob ex den zu stellenden Anforderungen genügt, soll. ein Prüfgerät dienen, das erfindungsgemäß aus einem aus elektrisch leitendem oder elektrisch leitend gemachtem Baustoff hergestellten Prüfkopf besteht, über den die zu prüfende Maske gezogen ist, die an bestimmten Stellen, im Innern des Maskenkörpiers, z. B. durch Anbringen von dünnen Meitallfolien, elektrisch leitend gemacht ist und der ,durch einen elektrischen Stromkreis mit ei!ner Klixagel oder einer anderen Anzeigevorrichtung derart elektrisch gekoppelt ist, daß. beim Berühren der leitend ,gemachten Stellern des MaskenkÖrpiers mit dem Prüfkogf infolge eines im Innern .der Maske, z. B. durch eine mit einem Druckmesser versehene Pumpe, er; zeugten Unterdruckes die Klingel, oder ein anderes akustisches oder optisches. Zeichen anspricht.To determine the strength of breathing from gas masks or for Determination of whether the mask body is too soft or whether it meets the requirements is enough, should. serve a test device that according to the invention consists of an electrical conductive or electrically conductive building material made of a test head, over which the mask to be tested is drawn, at certain points inside of the mask body, e.g. B. by attaching thin Meitallfolien, electrically conductive and which is made by an electrical circuit with a Klixagel or another display device is electrically coupled such that. when touching the conductive, made controls of the mask body with the test head as a result of a inside .the mask, e.g. B. by a pump provided with a pressure gauge, he; testified negative pressure the bell, or some other acoustic or optical. sign appeals to.
Die .dünnen Metallfolien sind insbesondere am Nassen- und Stirnteil des M.askenköTpexs angebracht. Das Leitendmachen kann' auch durch Bronzieren geschehen. Die Verhindung der leitend gemachten Stellen im Inneem des Maskenkörpers mit dem außerhalb des Prüfkopfes befindlichen - Anzeigegerät, z. B. der elektrischen. Klingel, erfolgt durch flache, isolierte Leitungen. Diese Leitungen brauchen nicht durch Bohrungen des MaskeinköTpers hindurchgeführt zu werden, sondern sie können zwischen dem Dichtrahmen und dem Prüfkopf verlegt werden.The thin metal foils are particularly on the wet and front part of the M.askenköTpex attached. Making it leading can also be done by bronzing. The connection of the places made conductive in the interior of the mask body with the located outside the test head - display device, e.g. B. the electrical. Bell, takes place through flat, insulated cables. These lines do not need through Holes of the MaskeinköTpers to be passed, but they can between the sealing frame and the test head.
Besteht beispielsweise die Vorschrjft, daß bei einem Einatemwiderstand von 3o man WS der Maskenkörper 'den Prüfkopf noch nicht be rühmen darf, so ist bei der Prüfung nur nötig, den Kolben der Pumpe langsam herauszuziehen, so daß die Wassersäule des Druckmessers auf 3o nun stehenbleibt. Ertönt kein Klingelzeichen, so hat die Maske den Prüfkopf noch nicht berührt. Ertönt aber das Zeichen, so ist das Mitatmen des Maskenkörpers zu stark.If, for example, there is a regulation that if there is an inhalation resistance from 3o one cannot praise the test head as yet, so is at The test only needed to slowly pull out the plunger of the pump, so that the water column the pressure gauge now stops at 3o. If the bell does not sound, it has mask has not yet touched the probe. But if the sign sounds so the breathing of the mask body is too strong.
Durch weitere Betätigung der Pumpe läßt sich auch feststellen, bei welchem Unterdruck die Klingel ertönt, wann also die Berührung stattfindet.Further actuation of the pump can also be used to determine when what negative pressure the bell sounds, i.e. when the contact takes place.
In der Zeichnung ist eine Ausführungsform des neuen Prüfgerätes dargestellt.In the drawing, an embodiment of the new test device is shown.
Abb. t ist eine Ansicht von der Seite, und Abb. a zeigt einen waagerechten Schnitt durch den Prüfkopf.Fig. T is a side view and Fig. A is a horizontal one Section through the test head.
Über den Prüfkopf a, der einerseits durch den Schlauch b mit der mit dem Druckmesser c versehenen Pumpe d und andererseits durch die Leitung/ über die Stromquelleeanit der elektrischen Klingel g in Verbindung steht, ist die zu prüfende Maske lt gezögen, die im Innern in der Nähe des Nasenteils Metallfolien i trägt, die durch die. Leitung k mit der Klingel g elektrisch gekoppelt sind. Wird die Pumpe d in Tätigkeit gesetzt, so tritt im Innern der Maske h ein gewisser, am Druckmesser c abzulesender Unterdruck -ein. Ist dieser Unterdruck stark genug, so legen sich die im Innern des Maskenkörpers. h angeordneten Metallfolien! auf die Oberfläche des Prüfkopfes a, wodurch der Stromkreis geschlossen und die Klingel g zum Tönen g@ebracht wird.The mask to be tested lt is pulled over the test head a, which is connected on the one hand through the hose b to the pump d equipped with the pressure gauge c and on the other hand through the line / via the power source anit the electric bell g, the mask to be tested lt, which is inside in the Near the nose part i carries metal foils, which through the. Line k are electrically coupled to the bell g. When the pump d is activated, a certain negative pressure, which can be read on the pressure gauge c, occurs inside the mask h. If this negative pressure is strong enough, they settle inside the mask body. h arranged metal foils! on the surface of the probe a, whereby the circuit is closed and the bell g is made to ring.
