Description
Ortsveränderliche Vorrichtung zum Feststellen von Gasausströmungen aus Gasleitungen Die Erfindung bezieht sich auf eine ortsveränderliche Vorrichtung zum Feststellen von Gasausströmungen aus Gasleitungen, bei -der in einem Gehäuse ein Korb untergebracht ist, in den katalytische Stoffe (z. B. Platin-Asbest) eingelegt sind, die sich beim Zutritt von Gas erwärmen, so daß die Wärme auf einen Ausdehnungskörper wirken kann, der über besondere Kontakteinrichtungen Stromkreise zu einer beliebigen Anzeigevorrichtung schließt.Portable device for detecting gas leaks from gas pipes The invention relates to a portable device for detecting gas leaks from gas lines, both in one housing a basket is housed in which catalytic substances (e.g. platinum asbestos) are inserted are that heat up when gas enters, so that the heat on an expansion body can act, which via special contact devices circuits to any Display device closes.
Es sind bereits ortsfeste Einrichtungen bekanntgeworden, bei denen bei unzulässigem Gasaustritt die Wärmte katalytischer Stoffe Kontakte schließt. Derartige Einrichtungen sind jedoch zufolge der Explosionsmöglichkeit eine große Gefahr. Auch sind schon Vorrichtungen gebaut worden, welche die Explosionsgefahren ausschließen, die aber derart teuer und umständlich in der Bedienung sind; so daß die Verwendung dadurch behindert wird.Fixed facilities have already become known where In the event of impermissible gas leakage, the heat of the catalytic substances closes contacts. However, such facilities are large due to the possibility of explosion Danger. Devices have also been built to reduce the risk of explosion exclude, which are so expensive and cumbersome to use; so that the use is thereby hindered.
Diesen übelständen abzuhelfen und ein ortsveränderliches .einfaches, billiges und ohne besondere Kenntnisse zu bedienendes und explosionssicheres Gerät zum Feststellen und Anzeigen von Gasausströmungen zu schaffen, ist Gegenstand vorliegender Erfindung. Das Wesen der Erfindung besteht darin, daß der obenerwähnte Korb als doppelwandiger, aus engmaschigen Drahtnetzen bestehender Behälter ausgebildet ist, an dessen Außenseife neben einer den :elektrischen Teil gasdicht abschließenden Gehäusezwischenwand ein Bimetallstreifen angeordnet ist. Durch diese Anordnung wird es auch erreicht, daß der elektrische Teil der Vorrichtung vollkommen gegen das Gas abgedichtet ist, so daß ein Verschmutzen der empfindlichen ielektrischen Teile nicht eintreten kann.To remedy these evils and a portable, simple, cheap and explosion-proof device that can be operated without special knowledge To establish and display gas leaks is the subject of the present Invention. The essence of the invention is that the above-mentioned basket as double-walled container consisting of close-meshed wire nets is formed, on its outside soap next to one that seals the electrical part in a gastight manner Housing partition a bimetallic strip is arranged. This arrangement will it also achieves that the electrical part of the device is completely against the Gas is sealed so that the sensitive dielectric parts are not contaminated cannot occur.
Auf der, Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsmöglichkeit schematisch dargestellt. Es zeigt Fig. i einen Querschnitt durch eine in die Erde verlegte Gasleitung mit der auf einem besonderen Prüfrohr aufgesetzten Vorrichtung nach der Erfindung und Fig. 2 einen Schnitt durch die Vorrichtung.. Ein, Gehäuse i ist durch eine Wand i i in zwei Kammern 5, 22 unterteilt. In der einen Kammer 22 ist ein doppelwandiger Korb 2 aus engmaschiglemDrahtnetz herausnehmbar untergebracht, .der mixt' hoch-empfindlichen Stoffen, z. B. Platin-Asbest q., gefüllt ist und auf einer Stütze 2 i ruhen kann. An einer :Seite des Korbes 2, gegenüber der Unterteilungswand i i, ist ein Bimetallstreifen 3 befestigt. Dieser drückt gegen einen Kontaktstift io, der durch die Unterteilungswand i i führt und in einem Bügel 12 gelagert ist. Der Kontaktstift i o schließt -einen Stromkreisunterbrecher 9 zu optischen und akustischen Anzeigevorrichtungen 7, 8, die mit einer Stromquelle 6 in einer Kammer 5 des Gehäuses untergebracht sind. Der Gehäusedeckel ist mit Abzugsöffnungen 2o verstehen. Dier Boden 13 kann ganz durchlässig sein. In- dem zeichnerisch dargestellten Anwendungsbeispiel ist eine öffnung zu der Kammer 22 vorgesehen, an der vermittels einer Verschraubung 14 ein Prüfrohr 15 befestigt werden kann, an ' dessen Ende eine konische Spitze 17 mit Löchern 18 und einerrri Bund r9 befestigt. sind.On the drawing, the subject matter of the invention is shown schematically in an exemplary embodiment. 1 shows a cross section through a gas line laid in the ground with the device according to the invention placed on a special test pipe and FIG. 2 shows a section through the device. A, housing i is through a wall ii in two chambers 5, 22 divided. In one chamber 22, a double-walled basket 2 made of close-knit wire netting is removably housed. It mixes highly sensitive substances, e.g. B. platinum asbestos q., Is filled and can rest on a support 2 i. On one side of the basket 2, opposite the partition wall ii, a bimetallic strip 3 is attached. This presses against a contact pin io, which leads through the partition wall ii and is mounted in a bracket 12. The contact pin io closes a circuit breaker 9 to optical and acoustic display devices 7, 8, which are accommodated with a power source 6 in a chamber 5 of the housing. The housing cover is to be understood with vent openings 2o. The bottom 13 can be completely permeable. In the application example shown in the drawing, an opening to the chamber 22 is provided, to which a test tube 15 can be attached by means of a screw connection 14, at the end of which a conical tip 17 with holes 18 and a collar r9 is attached. are.
Beim Gebrauch wird das Rohr 15 mit '@. konischen Spitze 17 auf das Steigrohr 23 d, Gasleitung 2¢ aufgesetzt und die Pumpe 16 betätigt, die am Saugrohr r 5 befestigt ist. Hierdurch wird das etwa ausströmende Gas in die Kammer 22 mit dem Drahtkorb 2 geführt und gelangt mit den darin gelagerten hochempfIndlichen Stoffen in Berührung. Die hierdurch frei werdende Wärme bringt den Bimetallstreifen 3 zum Ausschlagen, _ so daß über Kontaktstift 1o und Unterbrecher 9 der Stromkreis zu den Anzeigevorrichtungen geschlossen wird. An Stelle des Bimetallstreifens kann auch ein Quecksilberthermometerschalter treten.In use, the tube 15 is marked with '@. conical tip 17 on the Riser pipe 23 d, gas line 2 ¢ attached and the pump 16 actuated, which is on the suction pipe r 5 is attached. As a result, any gas flowing out is carried into the chamber 22 with it the wire basket 2 and arrives with the highly sensitive substances stored in it in touch. The heat released as a result brings the bimetal strip 3 to Knock out so that the circuit is closed via contact pin 1o and breaker 9 the display devices is closed. Instead of the bimetal strip can also kick a mercury thermometer switch.
Das besondere Saugrohr und die Pumpe dienen lediglich zum schnelleren Heranholen der Luft mit etwaigem Gasgehalt zu der Prüf-The special suction pipe and the pump are only used to speed things up Bringing the air with any gas content to the test
