Claims

[Scope of utility model registration request]

A flow path control valve mechanism for a water softener, etc., which operates a main valve, a reclaimed water valve, etc. using a predetermined cam mechanism, and switches the flow path between water passage, backwashing, regeneration, rapid flushing, and water replenishment. , a valve body 7 elastically supported by the casing 1, a valve chamber 10 communicating with the reclaimed water passage 9 and the raw water passage 4, and a valve 2 that moves within the valve chamber 10.
has a semicircular passage 13a at the tip approximately in the center, and a passage 3 communicating the semicircular passage 13a with the valve chamber 10, and a semicircular passage 13a in the approximately central part of the raw water passage 4 facing the valve 2. A valve seat 12 having a circular passage 13b is protruded, and when the valve 2 moves in the valve chamber 10 against a spring and seats on the valve seat 12 of the raw water passage 4, the valve 2 and the valve The respective semicircular passages 13a and 13b of the seat 12 form a small circular passage 13, and when the valve 2 moves against the spring to the intermediate position of its stroke, the raw water passage 4 and the A flow path control valve for a water softener or the like, characterized in that the flow path is switched by communicating the semicircular port 13a of the valve 2, the passage 3, the valve chamber 10, and the reclaimed water passage 9.
