Abstract

The electrically-controlled protection equipment is for pipes, hoses etc. delivering electrically-conductive liq. media to user units. If liquid discharge becomes uncontrolled, this is detected and the flow shut off. A solenoid valve is mounted in the fixed part of the pipe upstream of the hose leading to the consumer unit. Leaking fluid strikes a detector under the latter, and which deenergises the solenoid valve via an amplifier, shutting off the flow.

Description

Beschreibung: Elektrisch gesteuerte Schutz w zum Absperren von lüssigkeitsleitungen. Description: Electrically controlled protection w to shut off liquid lines.

Zweck der Erfindung ist es, Flüssigkeitsschäden im Zusammenhang mit dem Gebrauch von flüssigkeitsgespeisten Geräten zu verhindern bzw. einzudämmen.Purpose of the invention is related to fluid damage to prevent or limit the use of liquid-fed devices.

Die Aufgabe ist erfindungmäßig dadurch gelöst, daB ein Magnetventil (M) im festen Teil der Zuleitung (H) vor dem Schlauchstück (S) zum Verbrauchsgerät (G) angebracht ist.The object is achieved according to the invention in that a solenoid valve (M) in the fixed part of the supply line (H) in front of the hose section (S) to the consumer device (G) is attached.

Wenn aus dem beschädigten bzw. schadhaften Schlauch Flüssigkeit austritt, trifft diese auf den unter dem Verbrauchsgerät befindlichen Fühler () und löst über den Schaltverstärker (v) das im Ruhezastand angezogene und damit geöffnete Magnetventil aus, so daß weiterer Flüssigkeitszulauf und Plüssigkeitsaustritt hinter dem Magnetventil verhindert wird.If liquid leaks from the damaged or defective hose, this hits the sensor () located under the consumer device and triggers over the switching amplifier (v) the solenoid valve, which is attracted and thus opened when idle off, so that further liquid inlet and liquid outlet behind the solenoid valve is prevented.

Ruhzustand bedeutet. daß die Spule des Magnetventils unter Spannung steht, damit dias Sperrstück zurückgezogen ist und der Zufluß frei ist.Means idle state. that the coil of the solenoid valve is energized stands so that the locking piece is withdrawn and the inflow is free.
