BYPASS VALVE WITH AN INTEGRAL FLOW SENSOR FOR A WATER TREATMENT SYSTEM

摘要

A bypass valve (10) includes a body (12) with first and second chambers (41, 43) connected by a bridge passage, an untreated water inlet (18) and untreated water outlet (20) both open into the first (16) chamber (41), and a treated water inlet (24) and a treated water outlet (22) both open into the second chamber. A first valve element (40) is rotatably received in the first chamber (41) alternately to connect the inlet to the untreated water outlet or the bridge passage. A second valve element (42) is rotatably received in the second chamber (43) alternately to connect the outlet to the treated water outlet or the bridge passage. A manually operable mechanism rotates the first valve element in the fist chamber and the second valve element in the second chamber. A flow sensor is received within either the first or second valve element within a flow meter cage (60) to measure the amount of water flowing through the bypass valve.
