Description
SchutzeinrichtungProtective device
Gegenstand der Erfindung ist eine Schutzeinrichtung, die dazu dient, das Ausströmen von Gas zu entdecken und die Explosionsgefahr in einem zu sichernden Raum zu verhindern.The invention relates to a protective device that serves to detect the escape of gas and to prevent the risk of explosion in a room to be secured.
Die erfindungsgemäße Einrichtung ist gekennzeichnet durch einen Gasdetektor in dem zu sichernden Raum und elektrische Alarmvorrichtungen und/oder elektrische Vorrichtungen zum Absperren der Gaszufuhr oder elektrische Vorrichtungen zum Einschalten einer Lüftungseinrichtung , die jeweils unter der Steuerung des Gasdetektors stehen.The device according to the invention is characterized by a Gas detector in the room to be secured and electrical alarm devices and / or electrical devices for locking the gas supply or electrical devices for switching on a ventilation device, each under the control of the gas detector.
Bei einer vorteilhaften Ausführungsform werden die elektrischen Vorrichtungen durch eine elektrische Einrichtung gespeist, bei der mindestens deren in dem zu sichernden Raum gelegener Teil abgeschirmt und explosionsgeschützt ist.In an advantageous embodiment, the electrical Devices fed by an electrical device, in which at least their part located in the space to be secured shielded and explosion-proof.
Bei einer solchen Einrichtung wird jedes Ausströmen von Gas in dem zu sichernden Raum sofort durch den Gasdetektor entdeckt, der automatisch eine Hupe und/oder ein sichtbares Alarmsignal auslöst. Außerdem wird die Gaszufuhr sofort unterbrochen und eine Lüftung des Raums veranlaßt, so daß jede ExplosionsgefahrWith such a device, any leakage of gas in the room to be secured is immediately detected by the gas detector, which automatically triggers a horn and / or a visible alarm signal. In addition, the gas supply is immediately interrupted and arrange for the room to be ventilated so that there is no risk of explosion

Ein Ausführungsbeispiel der Erfindung wird nun anhand der einzi-*· gen Figur beschrieben, die schematisch eine perspektivische An-r sieht einer erfindungsgemäßen Schutzeinrichtung -darstellt.An embodiment of the invention will now be based on the single * · gen figure described, which schematically shows a perspective An-r sees a protective device according to the invention -represents.
Die in der Zeichnung schematisch dargestellte Schutzeinrichtung dient dazu, den Schutz eines Raumes, beispielsweise einer Küche, gegen eventuelles Ausströmen von Gas und die Explosionsgefahr, die sich daraus ergeben könnte, zu gewährleisten. The protective device shown schematically in the drawing is used to protect a room, for example a kitchen, to ensure against possible gas leakage and the risk of explosion that could result from it.
Diese Einrichtung umfaßt im wesentlichen einen Gasdetektor 2 jedes geeigneten, an sich bekannten Typs, der im Inneren des ι Raumes 1 angeordnet ist, und elektrische Vorrichtungen, näm-■ lieh eine Hupe und/oder eine optische Alarmvorrichtung 3> eine Vorrichtung 4- zum Verschließen der Gaszufuhr und eine Vor-[ richtung 5 zum Einschalten einer Lüftungseinrichtung.This device essentially comprises a gas detector 2 of any suitable type known per se, which is located inside the ι space 1 is arranged, and electrical devices, namely ■ borrowed a horn and / or an optical alarm device 3> a device 4- for closing the gas supply and a pre [ direction 5 to switch on a ventilation device.
; Die verschiedenen elektrischen Vorrichtungen 3» 4-, 5 werden .: durch eine elektrische Einrichtung 7 versorgt, bei der mindestens ihr im Inneren; des Raumes 1 gelegener Teil abgeschirmt und explosionsgeschützt ist. Die Einrichtung 7 besteht im wesentlichen aus einer Leitung 11 zum Zuführen von Strom, einem die Spannung verringernden Umformer 12, einem ; Gleichrichter 13» einer autonomen Sicherheits-Hilfsquelle 14-, die beispielsweise durch eine Akubatterie gebildet wird,und einem ferngesteuerten Relais 16, an welches die Versorgungsleitungen der elektrischen Vorrichtungen 3, 4-, 5 angeschlossen sind.; The various electrical devices 3 »4-, 5 become .: powered by an electrical device 7, in which at least you inside; the part located in room 1 is shielded and is explosion-proof. The device 7 consists essentially of a line 11 for supplying Current, a voltage reducing converter 12, a; Rectifier 13 »of an autonomous safety auxiliary source 14-, which is formed, for example, by an accumulator battery, and a remote-controlled relay 16, to which the supply lines of the electrical devices 3, 4-, 5 are connected are.
; Im allgemeinen wird die Alarmvorrichtung 3 und auch die Vor- ! richtung 4 zum Absperren der Gaszufuhr in Form, eines elektromagnetischen Schiebers im Innern des Raumes 1 angeordnet sein. ; In general, the alarm device 3 and also the ! direction 4 to shut off the gas supply in the form of an electromagnetic slide in the interior of the room 1 be arranged.
Die Lüftungseinrichtung kann eine Klappe oder ein Ventil sein, die sich zu der Umgebungslu-ft hin öffnen, eventuell in Verbindung mit einem Ventilator, um die Evakuierung desThe ventilation device can be a flap or a valve that open to the ambient air, possibly in conjunction with a fan to facilitate evacuation of the
J in dem Raum 1 verteilten Gases zu gewährleisten und um die j Luft im Inneren desselben zu erneuern.To ensure the gas distributed in the room 1 and to renew the air inside it.
Die !Funktionsweise ist die folgende: Im lalle eines Ausströmens von Gas im Innern des Raumes 1 schließen sich, gleich nachdem die Anreicherung der Luft mit Gas den kritischen Regelpunkt des Gasdetektors 2 erreicht hat, dieThe mode of operation is as follows: In the form of an outflow of gas inside the room 1 close immediately after the enrichment of the air with gas has reached the critical control point of the gas detector 2, the
