Abstract

Det er foreslått et overvåkningssystem for sikring mot lekkasje- og oversvøirumelsesskader ved vannforsyningen til f .eks. et bolig- hus. Dette omfatter en elektrisk styringsenhet (4) tilknyttet i det minste ett elektrisk følerelement (3) , samt en på vannfor- syningsledningen (1) tilknyttet magnetventil (2) (shut-off- valve). Magnetventilen (2) er innrettet til å energiseres av styringsenheten (4) for sperring av vanntilførselsledningen (1) straks et følerelement (3) påvirkes med vann eller væske. Den elektriske styringsenheten (4) er innrettet til å påtrykke følerelementet (3) en vekselspenning som er vesentligere lavere enn vanlig nettspenning . Det er også foreslått en holdekrets i styringsenheten (4) for å sikre lukning av magnetventilen (2) selv om vann- eller væskepå- virkningen på følerelementet (3) skulle opphøre, samt at den nevnte holdekretsens sikring kun kan oppheves ved et manuelt betjenbart bryterorgan.A monitoring system has been proposed for protection against leakage and flooding damage at the water supply to e.g. a residential house. This comprises an electrical control unit (4) connected to at least one electrical sensor element (3), and a shut-off valve (2) connected to the water supply line (1). The solenoid valve (2) is arranged to be energized by the control unit (4) for blocking the water supply line (1) as soon as a sensor element (3) is actuated with water or liquid. The electrical control unit (4) is arranged to apply an alternating voltage which is substantially lower than normal mains voltage to the sensor element (3). Also provided is a holding circuit in the control unit (4) to ensure closure of the solenoid valve (2) even if the water or liquid influence on the sensor element (3) should cease, and that the safety of said holding circuit can only be deactivated by a manually operable switching means. .
