Description
Technical Field
[0001] The utility model relates to the technical field of non-negative pressure water supply, in particular to a non-negative pressure water supply device with a cabinet structure. Background Art
[0002] The non-negative pressure water supply equipment is a pressurized water supply unit, one end of which is connected to the municipal water supply network, and is connected in series with the residual pressure of the municipal network to supply water to ensure that the pressure is not less than the set protection pressure of the secondary pressurized water supply equipment. The core of the water supply equipment is to prevent the generation of negative pressure during the secondary pressurized water supply process to ensure that users use water safely, reliably and stably. However, when tap water enters the existing cabinet-type negative pressure water supply equipment, impurities such as scale will gradually appear on the bottom or inner wall after long-term use, affecting the water quality, but it is not easy to clean; after tap water is injected into the flow regulator, The internal pressure will increase, and the negative pressure suppressor needs to be opened to allow the air to be discharged to the outside to balance the air pressure. However, when the air enters the interior of the flow regulator, a fixed-structure filter is used to filter the air. The filter chip is difficult to replace or clean, which increases the degree of blockage of the filter membrane. Replacing a new filter increases the cost of use. When the water inside the flow regulator is drained to flush the scale accumulated inside, when the water is drained through the drain valve, if there is a leak at the position of the drain valve, it is difficult to detect. After the drain valve is closed, it is difficult to detect the leak when the flow regulator is re-injected with tap water. Utility Model Content
