自动软水器由多路控制阀，树脂罐，盐罐和管道系统组成。
The automatic water softener is composed of multi-channel control valve, resin tank, salt tank and pipeline system.
软水器一般分为单阀单罐、单阀双罐和双阀双罐，单阀单罐只能单一供水、单一再生，无法做到连续供水，单阀双罐一个罐供水时另一个备用，当供水完成后会自动切换到备用罐继续供水，供水、再生两个罐轮流进行，这样来回的循环往复，从而可以实现24小时不间断供水。双阀双罐两个罐同时供水，错开再生，即当其中一个罐子再生时，另一个供水，从而可实现24小时连续供水。
Water softeners are generally divided into single valve and single tank, single valve and double tank and double valve and double tank. Single valve and single tank can only supply water and regenerate water, so continuous water supply cannot be achieved. When one tank of single valve and double tank supplies water, the other is standby. When the water supply is completed, it will automatically switch to the standby tank to continue to supply water. The two tanks of water supply and regeneration take turns, so that round-trip water supply can be realized, so that 24-hour uninterrupted water supply can be realized. Double valve double tank two tanks supply water at the same time, staggered regeneration, that is, when one tank regenerates, the other supplies water, so that 24-hour continuous water supply can be realized.
