AI Technical Summary
In existing negative pressure water supply equipment, the float detection method is prone to inaccuracy when supplying large or small flow rates of water. Furthermore, the float can deform over time, leading to inaccurate detection and affecting the stability and efficiency of the equipment.
The detection device includes a housing, a pressure chamber, and a triggering mechanism. Through the magnetic linkage of the top plate, the drive block, and the slider, the pressure change inside the tank triggers the booster pump, thereby achieving precise regulation of the pressure inside the tank, independent of the water supply flow rate.
It achieves automatic adjustment based on the gas pressure inside the tank, avoiding the impact of changes in water supply flow on the detection, improving the stability and service life of the equipment, and achieving the effect of saving electricity and energy.
