[0002] Demineralized water refers to the finished water obtained after removing impurities such as suspended solids, colloids, inorganic cations, and anions in water by using various water treatment processes. Demineralized water does not mean that all salts in the water are removed completely. Due to technical reasons and considerations of water production cost, according to different uses, demineralized water is allowed to contain trace impurities. The fewer impurities in demineralized water, the higher the water purity.

[0003] Common demineralized water technologies include reverse osmosis, electrodialysis, distillation, and ultrafiltration, etc. Among them, reverse osmosis technology is more common. In reverse osmosis technology, the separation of salt water in raw water is mainly achieved through a reverse osmosis membrane. Since the reverse osmosis membrane is prone to blockage and needs to be cleaned regularly, and the staff cannot replace the reverse osmosis membrane in time, the filtration efficiency of the reverse osmosis membrane is reduced and needs to be improved.

The first sealing head 73 is inserted and fixed on the fixed frame 3; this structure avoids the phenomenon of reverse flow through the check valve 72; connection sleeves 74 are movably connected to both the first sealing head 73 and the second sealing head 78.

A salinity measuring instrument 91 is fixedly connected to the connection nut 92; this structure can detect the salt content in the filtered water through the salinity measuring instrument 91.
