Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to an electromagnetic positioning plunger type hard water-free bypass soft water valve used for water purification equipment. Background Art

[0002] The water softener is a key component of the water softener. It mainly controls the water flow and regulates the regeneration process. Through the water softener, the water can be softened and the calcium, magnesium and other ions in the water can be removed, thereby reducing the hardness of the water and making the water softer. It has a good effect on some scenes that require the use of soft water, such as washing and bathing.

[0003] The soft water valve usually has the following structure:

[0004] Valve body: It is the main part of the entire soft water valve, providing a channel for water flow.

[0005] Valve core: used to control the direction and flow rate of water flow, and realize various functions through its movement or rotation.

[0006] Driving device: It can be a motor, electromagnetic device, etc., used to drive the valve core to move.

[0007] Sensors: such as flow sensors, hardness sensors, etc., are used to monitor relevant parameters of water so that the soft water valve can make corresponding adjustments.

[0008] Connection ports: including water inlet, water outlet, regeneration liquid inlet, etc., used to connect to external pipelines.

[0009] Internal control circuit or mechanism: used to coordinate and control the operation of various parts of the soft water valve to achieve automatic control and operation logic.

[0010] Sealing components: ensure the sealing between the various parts of the valve body to prevent water leakage.

[0011] The plunger type soft water valve is a type of soft water valve, and its advantages include:

[0012] Precise control: Ability to precisely control the direction and flow of water flow, ensuring stable operation and efficient regeneration of the water softener.

[0013] Long life: Since the movement of the plunger is relatively simple and the wear is small, the plunger type soft water valve has a long service life.

[0014] High reliability: relatively simple structure, low failure rate and high operational reliability.

[0015] The existing plunger type soft water valve also has some disadvantages:

[0016] 1. In order to achieve no hard water bypass during regeneration, the existing plunger type soft water valve has a hard water bypass in the control valve itself. In order to achieve soft water bypass, most of them use an additional closing component, which is costly and complex to control.

[0017] 2. The existing control valve uses monitoring current to determine the reference point. If the current increases during operation, the reference point may be misjudged. It is difficult to accurately determine whether the current monitoring is the true reference position, causing the control valve to operate in disorder and cannot be used normally.
