[0021] Please refer to Figure 1 The communication pipe 22 is fixedly provided with a back gas pipe 26 near the filter cartridge communication block 23; the back gas pipe 26 is connected with the communication pipe 22; the inner side of the back gas pipe 26 is embedded with a valve three 27.

[0022] Please refer to Figure 1 The lower side of the tank body 10 is fixedly connected with a sewage pipe 24; the inner side of the sewage pipe 24 is embedded with a valve two 25; the sewage pipe 24 is connected with the inner side of the tank body 10; by setting the sewage pipe 24 and the valve two 25, the inner side of the tank body 10 is easy to clean, the cleaning efficiency is improved, and the labor is saved.

[0023] Please refer to Figure 1The water inlet pipe 18 is provided with a check valve 17 at the joint with the submersible pump 16, so that the water flow drawn in by the submersible pump 16 can only flow into the water inlet pipe 18 in one direction.

[0024] Please refer to Figure 1 The lower side of the tank body 10 is fixedly connected with an emergency water pipe 28; the tank body 10 is in communication with the emergency water pipe 28; a valve four 29 is embedded in the inside of the emergency water pipe 28; by providing the emergency water pipe 28 and the valve four 29, the water flow in the inside of the tank body 10 is controlled by the valve four 29, which is convenient for emergency use and improves the convenience; when the flow rate of the water flow flowing out of the emergency water pipe 28 becomes slow, the back gas pipe 26 is opened, the air pressure at the emergency water pipe 28 is increased, the normal flow of the water flow at the emergency water pipe 28 is facilitated, and the stability of the emergency water is improved.

[0025] Please refer to Figure 1 The inside of the three filter cartridges 19 is embedded with porous sponge filter elements.

[0026] Please refer to Figure 1 The pressure booster controller 11 is electrically connected with the pressure gauge 13 and the pressure sensor 14 respectively; the pressure booster controller 11 is electrically connected with the submersible pump 16.

[0027] Please refer to Figure 1 The safety valve 15 is a one-way pressure relief valve, so that when the water pressure in the inside of the tank body 10 is too large, the tank body 10 is relieved to protect.

[0028] In work, the input end water suction pipe on the submersible pump 16 is inserted into the water well, then the pressure booster controller 11 is operated, so that the submersible pump 16 starts to draw water, the input end water suction pipe of the submersible pump 16 draws well water from the water well into the inside of the submersible pump 16 and transports it to the water inlet pipe 18; after the well water flows out of the submersible pump 16, due to the large water pressure, the well water enters the inside of the water inlet pipe 18 after opening the check valve 17, and then is transported into the inside of the tank body 10; then the well water gradually fills the inside of the tank body 10; after the inside of the tank body 10 is filled, when the water pressure in the inside of the tank body 10 reaches a specified value, the submersible pump 16 can be temporarily stopped, so that the well water flows into the communication pipe 22 at a constant pressure, the water pressure in the inside of the water supply pipe is within a certain range, that is, the pipe tap water supply and the case, after the well water passes through the communication pipe 22, it enters the inside of the filter cartridge communication block 23; due to the principle of the communication device, the well water entering the filter cartridge communication block 23 will first flow through the inside of the filter cartridge 19, and be filtered by the filter elements in the inside of the filter cartridge 19; after the well water is filtered in the inside of the filter cartridge 19, it becomes more pure, then after the well water enters the inside of the water pipe 20 through the filter cartridge communication block 23, it can be discharged by only opening the valve one 21;

[0029] Since the tank 10 side is provided with pressure gauge 13, pressure sensor 14, safety valve 15 in turn, by observing the pressure gauge 13, can accurately read the liquid pressure inside the tank 10, while through the signal transmission of pressure sensor 14, using the booster controller 11 to control the submersible pump 16 constant pressure pumping; Since the check valve 17 can only one-way flow, so by controlling the input pressure of the submersible pump 16, that is, the water supply pressure can be stably controlled, and then the well water fills the inside of the tank 10 using the principle of communicating vessels, the water flow is output from the water pipe 20 at a constant pressure; The standard head of the submersible pump 16 is preferably 30-40 meters, and the standard head of the submersible pump 16 is below 80 meters. Since the head of the submersible pump 16 cannot be too low or too high, the head of the submersible pump 16 is too low, and the delivery power cannot meet the demand, and the head is too high, which will cause the water flow pressure to be too large and damage other components.

[0030] The installation position of the booster controller 11 should be higher than the ground 1.6 meters, away from the harsh environment, moisture-proof, sun-proof, rain-proof, and checked before use.

[0031] When using for a long time, the inside of the tank 10 needs to be cleaned; At this time, the submersible pump 16 is started to pump well water into the inside of the tank 10, and then the valve 25 is opened to discharge impurities from the drain pipe 24; After cleaning, the submersible pump 16 is closed, the valve 27 is opened, the air flows through the return pipe 26 and the communicating pipe 22 inside, and at the same time, since the return pipe 26 is set at a higher position and communicates with the atmosphere, the air pressure at the drain pipe 24 is increased, so that the water flow can flow out of the drain pipe 24.

[0032] When power failure or water failure occurs, first close the valve 27 and the valve 21, open the valve 29, and discharge the well water stored in the tank 10 through the emergency water pipe 28 as emergency water to prevent operation failure from affecting normal water use.
