Device for the regulation of the quantity of water used for the regeneration of ion-exchange resins for the softening of water. The device comprises means for the selection of a pre-defined flow of water to be supplied to said ion-exchange resins for regeneration of the same, and means acting to allow filling of a combination of tanks (40, 42, 44) which can be selected from among a plurality of combinations of tanks (40, 42, 44), each combination comprising one or more of said tanks (40, 42, 44), said means for enabling filling of a combination of tanks (40, 42, 44) comprising a mobile part (64) and a fixed part (62) having reciprocal matching parts such that pre-defined angular positions of the mobile part (64) correspond to a respective combination of discharge, comprising one or more of said tanks (40, 42, 44) such as to form said selected flow of regeneration water. The device comprises means extending peripherally between the peripheral surface of the fixed part (62) and the peripheral surface of the mobile part (64) and acting to push radially and create a seal between the same. <IMAGE> |
