The utility model is realized by the following technical scheme:
as shown in fig. 1 to 4, a water purification system with a pressure regulating function comprises a water inlet pipeline 11, a pure water outlet pipeline 12, a first pipeline 13, a waste water pipeline 14, a backflow pipeline 15 pre-filtering mechanism 2, a reverse osmosis filtering mechanism 3, a pressurizing mechanism 4, a water storage mechanism 5 and a pressure regulating mechanism 6; in this scheme, the pre-filtration mechanism 2 is mainly used for filtering larger particles in raw water to obtain purified water, and the purified water passes through the reverse osmosis filtration mechanism 3 to obtain purified water meeting the drinking standard.
Specifically, the water inlet pipeline 11 is connected with the water inlet end of the pre-filtering mechanism 2 and is used for inputting raw water; the first pipeline 13 is connected between the water outlet end of the pre-filtering mechanism 2 and the water inlet end of the reverse osmosis filtering mechanism 3, and the pressurizing mechanism 4 is arranged on the first pipeline 13; the pure water outlet pipeline 12 is connected with the water outlet end of the reverse osmosis filtering mechanism 3 and is used for outputting pure water; the pressurizing mechanism 4 is used for increasing the water pressure and enabling the reverse osmosis filtering mechanism 3 to perform reverse osmosis.

In the embodiment of the utility model, in order to reduce the TDS value of the first cup of water when the water purification system is standing, one end of the backflow pipeline 15 is communicated to the purified water outlet pipeline 12, the other end of the backflow pipeline is communicated to the water storage mechanism 5, and the pressure regulating mechanism 6 is positioned in the water storage mechanism 5 and connected with the port of the backflow pipeline 15, so that the water pressure in the purified water outlet pipeline 12 is equal to the water pressure in the water storage mechanism 5 when the purified water outlet pipeline 12 is closed. When the system is kept still, namely the pure water pipeline is closed, forward osmosis can occur on the reverse osmosis filtering mechanism, the system enables the water pressure of the pure water pipeline to be equal to the water pressure of the water inlet pipeline through the pressure regulating mechanism, and when the reverse osmosis filtering mechanism is in forward osmosis, the pressure of the pure water end and the raw water end of the reverse osmosis filtering mechanism can be dynamically regulated to keep equal pressure, and the water pressure of the two ends can be slightly changed due to the dynamic regulation process, so that the system can be regarded as approximately equal.

The water is not needed to be discharged, so that the problem of water resource waste is solved.
The principle of the scheme is that the forward osmosis speed of the reverse osmosis filtering mechanism 3 is reduced by isobaric forward osmosis, the principle is that the increase of pressure and the increase of water quantity passing through the reverse osmosis filtering membrane show a linear relationship, as the reverse osmosis filtering membrane cannot completely intercept soluble salts in water, the rate of the water passing through the membrane is faster than the rate of the salt transferring along with the increase of pressure, and the desalination rate can be gradually increased. The scheme reduces the pressure difference on both sides of the membrane when positive permeation occurs through the pressure regulating mechanism 5, thereby reducing the speed. The constant pressure forward osmosis is slow and can be maintained for a plurality of hours. The system limits the permeation of RO membrane highly concentrated water to the pure water direction, and effectively solves the problem of high TDS of the first cup of water after long-time standing.

Although the scheme is theoretically that the waste water is re-collected and then re-utilized, in the continuous recycling process, the TDS value in the water storage mechanism 5 is always increased, and the TDS detector is arranged in the water storage mechanism 5, so that when the TDS value of the waste water in the water storage mechanism 5 exceeds a certain value, the waste water in the water storage mechanism 5 is discharged and is not led into a water inlet pipeline, and the service life of the reverse osmosis filtering mechanism is prolonged.
In addition, the pressure reducing valve 111 is added to the water inlet pipe, so that the water pressure at the water inlet end can be reduced, and the service life of the reverse osmosis filtering mechanism is prolonged after the water pressure at the water inlet end is reduced through experiments.

When the system is kept still, namely the pure water outlet pipeline 12 is closed, forward osmosis can occur on the reverse osmosis filtering mechanism, so that the TDS value of pure water kept in the pure water outlet pipeline 12 can be increased, when the system is used, the high TDS condition can occur on water discharged by the pure water outlet pipeline 12, so that the existing water purifying system has the condition that the TDS value of the first cup of water is too high, and the system enables old water in the pure water outlet pipeline 12 to be pumped back to the water inlet end of the reverse osmosis filtering mechanism through the second backflow pipeline 18, so that the problem of high TDS of the first cup of water after long-time standing is effectively solved.
