[0001] The utility model relates to the technical field of urban water supply, in particular to a tank-type non-negative pressure water supply device with a waterproof overflow function. Background Art

[0002] With the acceleration of urbanization, the safety and stability of urban water supply systems have become an increasingly important issue. Although traditional water supply systems can meet basic water needs, they still have certain limitations in terms of water quality assurance. Especially when the water source is polluted or the water quality is unstable, it is often difficult to completely remove harmful substances and pathogens by relying solely on conventional processes and pretreatment methods. Therefore, deep treatment of urban water supply systems to ensure that the water quality meets the standard for direct drinking has become an urgent problem to be solved.

[0003] In the existing urban water supply system, the flow compensation tank, as a common water delivery equipment, plays an important role in storing and delivering water. However, as time goes by, various impurities such as particulate matter and microorganisms will gradually accumulate inside the flow compensation tank. These impurities will not only affect the water supply quality, but may also cause potential harm to the water supply system. Therefore, it is essential to regularly clean and maintain the flow compensation tank.

[0004] However, the traditional cleaning method often requires draining all the water in the steady flow compensation tank, and even requires dismantling some pipes to operate. Such operations are not only cumbersome and inefficient, but also easily lead to waste of water resources. In addition, the sewage generated during the cleaning process also needs to be specially treated, which further increases the difficulty of cleaning and maintenance. Based on this, it is necessary to study a tank-type non-negative pressure water supply equipment with a waterproof overflow function. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a tank-type non-negative pressure water supply equipment with a waterproof overflow function, which effectively solves the problem that the steady flow compensation tank in the existing water supply structure needs to be frequently dismantled for maintenance and cleaning, and the impurities produced by cleaning need to be handled by an independent structure, which makes maintenance and cleaning difficult and inconvenient to operate.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a tank-type non-negative pressure water supply equipment with a waterproof overflow function, including a steady flow compensation tank, a water inlet system, a drainage system and a bypass system; the upper part of the steady flow compensation tank is provided with a vacuum suppressor, a pressure gauge and a water inlet, and the lower part thereof is provided with a drainage port and a bypass port;

[0007] The water inlet system includes a water inlet pipe, a pressure gauge, a water inlet check valve and a water inlet filter; the water inlet pipe is connected to external water and is connected to the water inlet via the pressure gauge, the water inlet check valve and the water inlet filter in sequence.

[0008] The drainage system includes a drainage pipe, a check valve, a valve and a load. The drainage pipe is connected to the load via the check valve, the valve and a water pump;

[0009] The bypass system includes a bypass pipe, a check valve, a valve, a water pump and a bypass filter; the bypass pipe is connected to the bypass port, and is connected to the water inlet of the bypass filter through the bypass pipe, the check valve, the valve, the water pump in sequence, and the bypass filter produces filtered water and clean water after filtration, wherein the filtered water is connected to the inlet of the water inlet filter through a pipeline, and the clean water is connected to the water inlet through a pipeline.

[0010] Furthermore, the bypass filter includes a shell and a filter screen; the filter screen is arranged obliquely in the shell, the lower part of the filter screen is a filter chamber, the upper part is a clean water chamber, the lower part of the filter chamber is connected to a filtered water drainage pipe, and the upper part of the water purifier is connected to a clean water drainage pipe.

[0011] Furthermore, a baffle extending toward the filter screen is provided on the lower inner wall of the filter chamber, and a gap exists between the baffle and the filter screen; and a guide area is formed between the baffle and the inner wall of the filter chamber, and a filtered water drainage outlet is provided inside the guide area.

[0012] Furthermore, a three-way valve is provided at a position of the water inlet pipe near the water inlet, and the filtered water is connected to a branch of the three-way valve through a pipeline.

[0015] The beneficial effect of the above technical solution is: the utility model structurally optimizes the input and output structure of the steady flow compensation tank, draws out water through a bypass, and during the circulation flushing process, uses the bypass to lead out the water source in the steady flow compensation tank and introduces it into the bypass filter for filtration. The impurity water produced by the filtration is further introduced into the water inlet filter for treatment, avoiding the addition of additional processing structures, centrally treating impurities, greatly simplifying the structure, and the produced clean water is directly sent to the steady flow filter for recycling.

[0016] Structurally, the setting of the bypass filter makes the filtering process more efficient and precise. The water source is effectively separated into filtered water and clean water through the inclined filter in the shell.

[0017] The baffle design at the bottom of the filter chamber not only optimizes the water flow direction and improves the filtration efficiency, but also enables the smooth discharge of filtered water through the filtered water drain port inside the diversion area. This design makes the filtration effect more significant and ensures the water supply quality.

[0018] Therefore, the structural design of the utility model realizes efficient, convenient and environmentally friendly water supply filtering and flushing functions, which is of great significance for improving water supply quality and ensuring water supply safety.
