Technical Field
[0001] The utility model relates to the technical field of high-level water tanks, in particular to an automatic water replenishment control device for a high-level water tank. Background Art
[0002] The automatic water replenishment control device of the high-level water tank is usually a device used to manage the water level of the water tank, which involves automatic control and water replenishment functions. This device usually includes a water level sensor, a control module and an actuator. The high-level water tank increases the water pressure through gravitational potential energy, which can meet the production and domestic water needs with high water pressure requirements. In the case of large water consumption, if there is no regulation of the high-level water tank, the water pressure may decrease, resulting in abnormal operation of industrial and domestic water. The high-level water tank can store water to deal with emergencies or large changes in water consumption. With a high-level water tank, the sustainability of production and domestic water can be guaranteed.
[0003] For example, the Chinese patent "CN213655097U" discloses an automatic water replenishment control device for a water pool, which proposes that: the water supply pump mechanism includes a water pump body and a water pump control cabinet, the water pump body is provided with a water supply pipeline connected to a high-level water tank, the water supply pipeline is provided with a pressure monitor, a floating hydraulic switch is provided in the high-level water tank, and the water inlet end of the high-level water tank is provided with a water replenishment electric valve connected to the water supply pipeline, and the water replenishment electric valve is connected to the floating hydraulic switch in communication. It can realize automatic water replenishment, reduce wiring costs, avoid frequent water pump startup, and extend the service life of the water replenishment device. The water replenishment liquid difference setting can meet the application requirements of matching with the variable frequency water pump, and reduce the water replenishment energy consumption. It has a delay control function. When the floating hydraulic switch fails or the power supply of the high-level water tank fails, the water supply pipeline can have a certain compensation water pressure, provide a water replenishment interval, prevent frequent triggering of the water pump, and extend the service life of the water pump.
[0004] It can be seen from the above-mentioned device that although the above-mentioned device has a delayed control function to extend the service life of the Yancheng water pump, the applicant believes that there are the following defects:
[0005] The existing device uses a sensor to detect the water level in the water tank during use. The equipment cost is high and relies on electricity to supply the detection. In addition, the cost of controlling the water replenishment inside the water tank by using an electromagnetic valve increases. In the event of a power outage, the water tank solenoid valve and sensor cannot be used normally, affecting the normal water supply of the water tank. Utility Model Content

A control rod 415 is arranged below the connecting plate 49, and the control rod 415 is movably installed inside the float valve 42. A water seal 416 is arranged on the outer wall of the control rod 415. Two limit plates 417 are relatively arranged on the inner wall of the float valve 42, and a valve 418 is arranged below the limit plate 417. The valve 418 is arranged at the lower end of the control rod 415. The adjusting component 5 includes an adjusting motor 51 and a slide groove 54.

The slider 53 is slidably installed inside the slide groove 54.
[0027] Working principle: First, when the high-level water pool is not filled with water, the control ball valve 1 is opened to allow water to enter the high-level water pool 3 through the water inlet pipe 2. When there is no water in the water pool, the float 414 is affected by gravity to drive the rocker arm 411 to tilt downward through the movement limit of the connecting plate 49. When the rocker arm 411 tilts downward, the control rod 415 simultaneously drives the valve 48 set inside the float valve 42 to move upward. When the valve 48 is driven to move upward, the water inlet flange 41 and the water outlet 419 inside the float valve 42 are in a connected water inlet state. At this time, water flows from the float valve 42 into the high-level water pool 3 to replenish water inside the high-level water pool 3. During the replenishment process, the water level continues to rise. When the water surface contacts the float 414 When the water level in the high-level water tank 3 reaches the required threshold, the valve 418 is completely fitted with the lower part of the inner wall of the float valve 42 and the lower part of the float valve 42 to form a sealed state, so that the water flow no longer enters the outlet pipe. When the water source in the high-level water tank 3 is used, the float 414 descends, and the valve 418 automatically rises again to replenish water.
[0028] Secondly, while the water volume inside the high-level water tank is controlled by the float 414, the adjusting motor 51 is used to drive the adjusting rod 413 to rotate, the slider 53 moves the adjusting motor 51 to limit the movement, and the adjusting rod 413 moves up and down through the surface thread to adjust the position of the float. The threshold of the water surface in the high-level water tank 3 is adjusted by the change in the position of the float 414.
