[0024] As Figure 1 shown, the embodiment of this application provides a water supply system for automatic water inlet and drainage of a raw water tank, including: a raw water tank 100, a first water supply pump 200, and a second water supply pump 300.

[0025] The water inlet of the raw water tank 100 is connected to the municipal tap water pipe network through a water inlet pipe 401. An inlet pressure gauge 101, a conductivity meter 102, and an inlet electric valve 103 are sequentially arranged on the water inlet pipe 401. A water inlet branch 402 is arranged in parallel beside the inlet electric valve 103, and a water inlet manual valve 104 is arranged on the water inlet branch 402. A direct water supply branch 403 is also arranged beside the inlet electric valve 103. One end of the direct water supply branch 403 is connected to the water inlet end of the inlet electric valve 103, and the other end is connected to the water inlet of the first water supply pump 200. A direct water supply manual valve 105 is arranged on the direct water supply branch 403.

[0026] The water outlet of the raw water tank 100 is connected to the water inlet of the first water supply pump 200 through a pipeline. The water outlet of the first water supply pump 200 is connected to the main water supply pipe 404. A pressure transmitter 106 and a main water supply valve 107 are connected in series on the main water supply pipe 404.

[0027] A raw water supply valve 108 is provided between the water outlet of the raw water tank 100 and the water inlet of the first water supply pump 200. A first water supply pump inlet valve 201 is provided in front of the water inlet of the first water supply pump 200, and a first water supply pump check valve 202 is provided at the water outlet of the first water supply pump 200.

[0028] A second water supply pump branch 405 is provided between the water inlet end of the first water supply pump inlet valve 201 and the water outlet end of the first water supply pump check valve 202. A second water supply pump inlet valve 301, a second water supply pump 300, and a second water supply pump check valve 302 are connected in series on the second water supply pump branch 405.

[0029] The drain outlet of the raw water tank 100 is connected to a drain pipe 406, and a drain electric valve 109 is provided on the drain pipe 406.

[0030] An overflow hole is provided on the upper side wall of the raw water tank 100, and the overflow hole is connected to the water outlet end of the drain electric valve 109 through a pipeline. A liquid level sensor 110 is provided in the raw water tank 100, and the overflow hole is set higher than the highest liquid level of the liquid level sensor 110.

[0031] During daily use, when the liquid level sensor 110 in the raw water tank 100 is at a high water level, the three valves of the water inlet electric valve 103, the water inlet manual valve 104, and the direct water supply manual valve 105 are all in the closed state.

[0032] When the liquid level sensor 110 is below the medium and low liquid level, the water inlet electric valve 103 is opened, the water inlet manual valve 104 and the direct water supply manual valve 105 are closed, and the water inlet branch 402 and the direct water supply branch 403 are open circuits. After the water supply pipe 401 obtains water supply from the municipal tap water system, the water inlet water pressure is detected by the water inlet pressure gauge 101, and the water inlet water quality is detected by the conductivity meter 102. When the water quality meets the standard, the raw water tank 100 is supplied with water through the water inlet electric valve 103.

[0033] When the water inlet electric valve 103 fails and cannot be opened, the water inlet manual valve 104 is opened. At this time, the water inlet electric valve 103 and the direct water supply manual valve 105 are closed, the water inlet branch 402 is in a conducting state, and the direct water supply branch 403 is an open circuit. After the water supply pipe 401 obtains water supply from the municipal tap water system, the water inlet water pressure is detected by the water inlet pressure gauge 101, and the water inlet water quality is detected by the conductivity meter 102. When the water quality meets the standard, the raw water tank 100 is supplied with water through the water inlet manual valve 104.

[0034] In this application, by providing a water inlet manual valve 104 in parallel with the water inlet electric valve 103, it is possible to avoid the situation where the water inlet electric valve 103 cannot supply water to the raw water tank 100 in case of a failure. When the water inlet electric valve 103 fails, the water inlet manual valve 104 is manually opened to prevent the raw water tank 100 from running out of water.

[0035] The original water tank 100 supplies water to the first water supply pump 200 and / or the second water supply pump 300 through the water outlet and the original water tank water supply valve 108. Usually, only one of the first water supply pump 200 and the second water supply pump 300 is turned on for water supply. The second water supply pump 300 serves as a backup for the first water supply pump 200. The second water supply pump 300 is only activated when the first water supply pump 200 fails or needs maintenance. That is, the first water supply pump inlet valve 201, the first water supply pump 200, and the first water supply pump check valve 202 are kept open daily, while the second water supply pump inlet valve 301, the second water supply pump 300, and the second water supply pump check valve 302 are kept closed, and the second water supply pump branch 405 is in an open circuit daily.

[0036] The water supply passes through the original water tank water supply valve 108, and after passing through the first water supply pump inlet valve 201, the first water supply pump 200, and the first water supply pump check valve 202, it enters the main water supply pipe 404. The main water supply pipe 404 supplies water to specific water-using units through the pressure transmitter 106 and the main water supply valve 107. The pressure transmitter 106 can detect the water supply pressure, and the main water supply valve 107 can control the opening and closing of the water supply to specific water-using units.

[0037] As described above, when the first water supply pump 201 fails or needs maintenance and shutdown, the first water supply pump inlet valve 201 and the first water supply pump check valve 202 are closed. At the same time, the second water supply pump inlet valve 301, the second water supply pump 300, and the second water supply pump check valve 302 are opened. The water supply passes through the original water tank water supply valve 108, and after passing through the second water supply pump inlet valve 301, the second water supply pump 300, and the second water supply pump check valve 302, the second water supply pump branch 405 is connected to the main water supply pipe 404 to form a path to supply water to specific water-using units.

[0038] When the original water tank 100 fails, needs maintenance or cleaning, the inlet electric valve 103 and the inlet manual valve 104 are closed, and the direct water supply manual valve 105 is opened. The inlet water branch 402 is in an open circuit, and the direct water supply branch 403 is in a path. After the water supply pipe 401 obtains water supply from the municipal tap water system, it passes through the inlet water pressure gauge 101 to detect the inlet water pressure, and the conductivity meter 102 to detect the inlet water quality. When the water quality meets the standard, it directly enters the direct water supply branch 403. Then, through the direct water supply branch 403, it enters the working first water supply pump inlet valve 201, the first water supply pump 200, and the first water supply pump check valve 202 or the second water supply pump inlet valve 301, the second water supply pump 300, and the second water supply pump check valve 302 in sequence, and then enters the main water supply pipe 404.

[0039] A direct water supply branch 403 and a direct water supply manual valve 105 are provided between the water supply pipe 401 and the original water tank 100 to form a short circuit for the original water tank 100. The tap water is directly supplied to the first water supply pump 200 or the second water supply pump 300, which can avoid the situation of water shortage and inability to use water in the backend system caused by maintenance, cleaning, etc. of the original water tank 100.

[0040] When the original water tank 100 needs to be repaired, it may also be necessary to drain the water stored in it. At this time, the drainage electric valve 109 can be opened from the system control interface. The water in the original water tank 100 passes through the lower drainage port, the drainage pipe 406, and the drainage electric valve 109, and then is discharged into the drainage ditch.

[0041] The drainage electric valve 109 is arranged at the bottom of the original water tank 100, which solves the problem of inconvenient emptying of the original water tank 100. When it is necessary to empty the original water tank 100, only need to click to open the drainage electric valve 109 on the system equipment control operation interface, and the original water tank 100 can be automatically emptied, with simple operation.

[0042] In order to avoid the safety risk of excessive water supply to the original water tank 100, an overflow hole is also arranged on the upper side wall of the original water tank 100. The position where the overflow hole is arranged can be higher than the highest liquid level of the liquid level sensor 110. In this way, when the liquid level sensor 110 fails and causes the water level in the original water tank 100 to be too high, the water can be discharged from the original water tank 100 through the overflow hole. The overflow hole is connected to the water outlet end of the drainage electric valve 109 through a pipeline, and the water discharged from the overflow hole can flow along the pipeline into the drainage ditch.

[0043] An overflow port is opened at a position above the high liquid level on the side of the original water tank 100, and the pipeline of the overflow port leads to the drainage ditch, ensuring that when the water inlet electric valve 103 of the original water tank 100 is stuck or fails and causes continuous water inlet, the water will be discharged to the drainage ditch through the overflow port, avoiding the occurrence of pipeline bursting and the machine room being flooded.

[0044] In the embodiment of the present application, the water supply system for automatic water inlet and emptying of the original water tank includes: the original water tank and the first water supply pump; the water inlet of the original water tank is connected to the municipal tap water pipe network through a water inlet pipe, and a water inlet electric valve is arranged on the water inlet pipe; a water inlet branch is arranged in parallel beside the water inlet electric valve, and a water inlet manual valve is arranged on the water inlet branch; the drainage port of the original water tank is connected to a drainage pipe, and a drainage electric valve is arranged on the drainage pipe; the water outlet of the original water tank is connected to the water inlet of the first water supply pump through a pipeline, and the water outlet of the first water supply pump is connected to the main water supply pipe. In the present application, a water inlet manual valve is arranged in parallel beside the water inlet electric valve, and when the water inlet electric valve fails, the water inlet manual valve can be started to supply water to the original water tank; by arranging the drainage electric valve, the drainage can be automatically opened during system maintenance, solving the problem of inconvenient emptying of the water tank, with simple operation.

[0045] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
