FLOW PASSAGE CONTROL VALVE

WIPO Patent Application WO/2014/049836

A1

A flow passage control valve (1) is formed by providing valves (6-13) in a valve housing (5) in which set flow passages are formed. A camshaft (48) for operating each of the valves (6-13) is provided in the left-right direction at the upper part of the valve housing (5). The valves (6-13) are divided into a first valve group (49) and a second group (50), which are arranged on both sides of the camshaft (48) in the front-rear direction. The first valve group (49) includes: a first water passage valve (6) which is provided in a first water passage (14) leading from a raw water inlet (22) to a pressure tank (3); a second water passage valve (7) which is provided in a second water passage (15) leading from the pressure tank (3) to a treated water outlet (23); and a bypass valve (8) which is provided in a bypass passage (24) for connecting the first water passage (14) and the second water passage (15). The second valve group (50) includes the remaining valves, which are not included in the first valve group (49). Separating the valves for a water system and the valves for a regeneration system facilitates the arrangement of a flow passage for each step and can provide a large water flow capacity.
