摘要： Disclosed is a water softener that includes a water softener valve and an ion exchange tank. The water softener valve includes a valve body and valve core assembly. The valve body includes a valve chamber, and a water inlet passage and a water outlet passage in communication with the valve chamber. The valve chamber, the water inlet passage, and the water outlet passage all extend in a first orientation, and the water inlet passage and the water outlet passage are both located at a periphery of the valve chamber and are disposed on opposite sides of the valve chamber in a second orientation. The water inlet passage and the water outlet passage respectively define a water inlet and a water outlet at a same end of the valve body along the first orientation. The second orientation and the first orientation are perpendicular to each other.
