Water softener control valve and control method thereof

Abstract

The invention relates to a water softener control valve and a control method of the water softener control valve. The water softener control valve comprises a control body. A water inlet, a water outlet, a sewage drainage opening, an outer filter element connector, an inner filter element connector and a salt suction opening. An ejector inlet, an ejector outlet, a magnetic valve inlet and a magnetic valve outlet are formed in the valve body, the ejector inlet and the ejector outlet are used for being connected with an ejector, and the magnetic valve inlet and the magnetic valve outlet are used for being connected with a magnetic valve. A fixed valve block and a movable valve block driven by a drive mechanism are also arranged in the valve body. A first through hole, a second through hole, a third through hole, a fourth through hole, a fifth through hole and a sixth through hole are formed in the periphery of the fixed valve block at intervals. A seventh through hole communicating with the sewage drainage opening is formed in the middle of the fixed valve block. The first through hole, the fourth through hole and the sixth through hole communicate with the outer filter element connector. The second through hole communicates with the inner filter element connector, the water outlet and the magnetic valve. The third through hole communicates with the salt suction opening and the ejector inlet. The fifth through hole is sealed. A water inlet hole and a breakover blind hole are formed in the periphery of the movable valve block. The water softener control valve is compact in structure and can achieve automatic switching of states of a water softener, and the control method is easy and convenient to implement.

Description

technical field [0001] The invention relates to a water softener control valve and a control method thereof. Background technique [0002] In water treatment applications, multi-functional soft water valves are often used to achieve functions such as softening, backwashing, salt absorption regeneration, positive washing, and water replenishment. Due to its simple structure and high reliability, the planar sealing multi-way valve has gradually become one of the main valve types in the field of multi-function control valves in recent years. However, due to the difficulty in the design of the planar valve, the number of holes in the valve plate of the planar valve is relatively large, which makes the internal flow path of the valve body complicated; second, in the softening process of the fixed bed, the regeneration of salt absorption is usually downstream regeneration, The downstream regeneration means that the brine flows downward from the upper part of the resin layer, and ...

Problems solved by technology

However, due to the difficulty in the design of the planar valve, the number of holes in the valve plate of the planar valve is relatively large, which makes the internal flow path of the valve body complicated; second, in the softening process of the fixed bed, the regeneration of salt absorption is usually downstream regeneration, The downstream regeneration means that the brine flows downward from the upper part of the resin layer, and the brine cannot fully contact with the resin layer, which consumes a lot of water; third, the existing water softener uses two valves, which is difficult to realize within one rotation of the moving valve. Realize the five major functions of softening, backwashing, downstream or countercurrent salt absorption regeneration, positive washing, and water replenishment in sequence. If they cannot be realized in sequence, the soft water valve will have to turn back and forth several times in order to realize a regeneration process flow, which will affect the soft water. valve life
