Description
Technical Field
[0001] The utility model relates to a water supply device, in particular to a water supply device used for fire fighting in buildings, belonging to the technical field of fire fighting water supply equipment. Background Art
[0002] In high-rise buildings, a fire extinguisher box is set up on each floor. Due to the high floors, in order to ensure that the water pressure for fire fighting is sufficient, the water needs to be pressurized for the second time. During the secondary pressurization, larger particles in the water need to be filtered to avoid clogging of the fire-fighting nozzles. The current secondary pressurized water supply facilities cannot automatically discharge the filtered impurities, resulting in manual cleaning of the filter device when using water for fire fighting. Moreover, the current secondary pressurization cannot ensure the stability of the water pressure, which can easily cause the water sprayed from the hydrant to be strong or weak at times.
[0003] Chinese patent number CN219604455U provides a secondary water supply device for building fire fighting, including a secondary water supply device, a pre-filtering assembly and a water tank at the upper end of the secondary water supply device, wherein the pre-filtering assembly includes an inlet pipe fixedly connected to one side of the water tank, and a filter cartridge fixedly installed at the lower end of the inlet pipe. The utility model discloses a secondary water supply device for building fire fighting, wherein the filter cartridge installed between the inlet pipe at the outer end of the water tank and the water delivery pipe can pre-filter the fire fighting water flow entering the water tank before entering, so as to prevent the impurities in the fire fighting water flow from accumulating at the bottom of the water tank after entering, causing the problem of clogging the pipeline during the use of the secondary water supply device, and the valve installed at the upper end of the inlet pipe and the water delivery pipe, and the movable cover threadedly connected to the bottom of the filter cartridge can realize the cleaning of the impurities at the bottom of the filter cartridge after filtering, and can also realize the disassembly and cleaning of the filter plate in the filter cartridge, and the cleaning operation is also convenient.
[0004] However, although the above case can filter the incoming water, it still requires manual cleaning of filtered impurities at regular intervals, and the water pressure after secondary pressurization cannot be guaranteed to be stable.
