Application principle of solenoid valve of water dispenser


In the process of using the water purifier, some sewage and impurities will be left inside the machine due to the filtration of filter element. If it is disassembled and cleaned, it will be very troublesome. Using the water inlet solenoid valve can complete the internal washing well and ensure the water purification effect of the product!

The ordinary inlet solenoid valve needs manual control to realize the flushing function. It needs to open the machine, then adjust the valve to complete the flushing, and flush for 60 seconds to complete. It is more complicated. The self-flushing water inlet solenoid valve is more convenient than the ordinary one. It will be equipped with an automatic flushing button outside the water purifier. As long as you press it and wait for about 18 seconds, the flushing effect can be completed. After the flushing, the sewage and impurities stored inside the machine can be very clear!

In the water purifier industry, there are three types of solenoid valves, namely, ordinary water inlet solenoid valve, self-flushing water inlet solenoid valve and self-flushing water inlet solenoid valve with wastewater proportional valve. Different kinds of products have similar principles and different functions.

Firstly, let’s talk something about the working principle of water purifier solenoid valve.

Working principle of water inlet solenoid valve: there is a closed cavity in the solenoid valve, and through holes are opened at different positions. Each hole is connected with different oil pipes. The piston is in the middle of the cavity, and two electromagnets are on both sides. The valve body will be attracted to which side when the magnet coil is energized. Different oil drain holes will be opened or closed by controlling the movement of the valve body. The oil inlet hole is normally open, and the hydraulic oil will enter Different oil drain pipes then push the piston of the oil cylinder through the oil pressure. The piston drives the piston rod and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the on-off current of the electromagnet.

Secondly, let have a look at the function of the water inlet solenoid valve.

It is a kind of product which can control the water flow of water purifier through electromagnetic control, and belongs to the automation basic component. The solenoid valve can cooperate with different circuits to achieve the desired control effect, and the control flexibility is very accurate. To put it simply, the function of the water inlet solenoid valve can realize the flushing effect of the water purifier!
