[0002] The liquid level controller controls the water pump operation system, which is a fully automatic control system. In existing systems, liquid level gauges, float valves, and pipe force valves are usually used to control water inlet. At the same time, existing systems are often connected to PLC systems for automatic control. However, existing systems usually have some problems, such as:

[0003] 1. The liquid level meter needs to be calibrated regularly when in use, otherwise it will affect the accuracy of water level measurement;

[0004] 2. The use of the float valve is prone to getting stuck on the internal support rod of the water tank due to poor contact and water level fluctuations, which can easily cause the water tank to overflow;

[0005] 3. When the PLC system stops, external communication will be interrupted, causing the water pump to stop running, affecting the effectiveness of water inflow and outflow from the water tank.

[0006] Therefore, in response to the above problems, a simple and reliable water tank water inlet and outlet control system is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1The shown embodiment shows a simple and reliable water tank inlet and outlet water control system, including a water tank 1, a liquid level controller 4 is provided on the water tank 1, the liquid level controller 4 includes a high liquid level probe 41, a middle liquid level probe 42 and a low liquid level probe 43, the high liquid level probe 41 is fixedly arranged at the top of the water tank 1, a water inlet structure is provided on one side of the water tank 1, the middle liquid level probe 42 is arranged on the side of the high liquid level probe 41, the middle liquid level probe 42 is used to detect the water level in the water tank 1, and the low liquid level probe 43 is arranged on the side of the middle liquid level probe 42. The high liquid level probe 41, the middle liquid level probe 42 and the low liquid level probe 43 are all cylindrical, and the high liquid level probe 41, the middle liquid level probe 42 and the low liquid level probe 43 are all stainless steel. The setting of stainless steel material can ensure the monitoring of the liquid level in the water tank 1 while reducing the occurrence of rust, thereby improving the effectiveness of the liquid level controller 4, extending the service life of the liquid level controller 4, and reducing the replacement cost of the liquid level controller 4.

[0023] The water inlet structure includes a water inlet manual gate valve 2 and a water inlet electric butterfly valve 3. The water inlet electric butterfly valve 3 is arranged between the water inlet manual gate valve 2 and the water tank 1. The water inlet manual gate valve 2 is arranged on one side of the water tank 1.

[0024] Specific reference Figure 1 , the liquid level controller 4 is connected to an external control power supply, the liquid level controller 4 is connected to the water inlet electric butterfly valve 3, the high liquid level probe 41 is extended into the water tank 1, and the high water level in the water tank 1 is monitored. When the high liquid level probe 41 contacts the liquid in the water tank 1, the water inlet electric butterfly valve 3 will be closed, and when the medium liquid level probe 42 does not contact the water, the water inlet electric butterfly valve 3 will be opened. At the same time, the water tank 1 will automatically replenish water until the high liquid level probe 41 stops after it is relieved of water. When the low liquid level probe 43 does not contact the water, the water pump 6 stops running. The existing water tank inlet and outlet water control system uses a liquid level meter and a float valve, The pipe force valve controls the water inlet. The system in this embodiment is not connected to the PLC and is used in parallel with the existing system. The liquid level gauge in the original system is only used for monitoring and is not used as a structure to control the start and stop of the water pump 6. The float valve is stopped. The high liquid level probe 41, the middle liquid level probe 42 and the low liquid level probe 43 cylindrical stainless steel rods in this system are set up without the need to correct the measurement deviation, and will not cause overflow in the water tank 1, avoiding waste of water resources and causing failures of other equipment and facilities. Moreover, when the PLC system is shut down, the system is still running and the water supply will not be interrupted, thereby ensuring the effectiveness of the water supply.

[0025] The top and the other side of the water tank 1 are connected to water pipes, and a water outlet structure is provided on the other side of the water tank 1. A bottom valve 7 is fixedly provided on one side of the water tank 1, and the water inlet manual gate valve 2 is connected to another water pipe. The water outlet structure includes a water outlet manual butterfly valve 5 and a water pump 6. The water outlet manual butterfly valve 5 is arranged between the water tank 1 and the water pump 6. The water pump 6 is fixed to one of the water pipes. The water pump 6 facilitates the water outlet control of the water source in the water tank 1.

One of the water pipes is connected to the water tank 1, and the water outlet manual butterfly valve 5 is installed on one of the water pipes, and cooperates with the setting of the water pump 6 to facilitate the output of the water source in the water tank 1. The setting of the water outlet manual butterfly valve 5 enables the system to still output the water source in the water tank 1 when the PLC is shut down in the original system, thereby ensuring the stability and effectiveness of the system operation. At the same time, the manual operation of the water outlet manual butterfly valve 5 can ensure stable water delivery while not easily causing overflow, and can avoid damage to other equipment due to overflow. The water tank 1 itself can also avoid damage caused by overflow, thereby improving the stability and orderliness of water source delivery, and also improving the safety of water inlet and outlet of the water tank 1.
