[0003] The prior art document with the announcement number CN213952379U provides a device linkage pressure balance type automatic water supply device. The device is provided with a frequency converter and a PLC controller. The pressure sensor arranged in the pressure equalizing tank can monitor the water pressure value in the pressure equalizing tank in real time and transmit the information to the PLC controller. The frequency of the frequency converter is controlled by the PLC controller to adjust the running power of the hydraulic pump driving motor, so that the constant pressure adjustment of the water pressure is realized. The electromagnetic valve on the water guide pipe is opened according to the demand. After the water pressure in the pressure equalizing tank is reduced, the above device can supplement the water pressure in time, realize constant pressure output, realize stable pressure automatic water supply of the equipment, and is suitable for popularization and use.

[0004] The prior art scheme in the above has the following defects although the structure of the prior art can realize the beneficial effects related thereto: when the water guide pipe bursts, the originally closed water channel becomes no longer sealed.

Protective measures such as a filter screen are arranged at the inlet of the pressure equalizing tank to prevent impurities from entering the pressure equalizing tank. If the filter screen is not cleaned in time, the stones and other impurities intercepted will reduce the flow of the water guide pipe, thereby affecting the balanced water supply of the water supply system. At present, the filter valve is mainly cleaned manually, and the cleaning efficiency is low.
