Cavitation jet flow self-cleaning non-negative pressure water supply system

Abstract

The cavitation jet flow self-cleaning non-negative pressure water supply system comprises a water tank, a water inlet pipe and a water outlet pipe are inserted into the side wall of the water tank in a penetrating mode, a blow-off pipe is inserted into the bottom of the water tank in a penetrating mode, and a water supplementing pipe communicated with the water inlet pipe is inserted into the upper end of the water tank in a penetrating mode; a sliding sleeve is connected to the inner wall of the water supplementing pipe through a suspension spring, a rotating box is rotationally connected to the side wall of the lower portion of the sliding sleeve in a sealed mode, a rotating water spraying mechanism is arranged in the rotating box, and a hydraulic cylinder is fixed to the upper end of the water tank. The self-cleaning device has the advantages that the whole self-cleaning process is carried out only when the water supply pressure is sufficient, the cleaning action is not triggered if the water supply pressure is insufficient, a water source in the water tank is ensured to be used for supplying water, water flow sprayed by the spray head cannot clean the inner wall of the water tank when the water supply pressure is insufficient, water supply is preferentially carried out, and then cleaning is carried out; and shutdown operation is not needed, and online descaling can be achieved.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a cavitation jet self-cleaning non-negative pressure water supply system. Background technique [0002] Non-negative pressure water supply equipment has become an indispensable part of people's domestic water, especially for communities, non-negative pressure water supply equipment is even more essential. Whether the secondary water supply is clean and hygienic and whether the facilities can operate normally is related to the people The health and quality of life of the masses are major livelihood issues. According to the management requirements of the urban secondary water supply system, water supply pipes, water tanks and other equipment must be cleaned and disinfected regularly, among which the cleaning and disinfection of the secondary water supply tank is the most critical On the one hand, the water tank stores a large amount of static water, which is easy to ...
