Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, in particular to a novel non-negative pressure tank with a movable cover. Background Art

[0002] With the intelligent control and transformation of water services, many residential areas and industrial and mining areas generally use energy-saving non-negative pressure water supply equipment for domestic water. In addition to the function of storing water, non-negative pressure tanks also prevent water pumps from directly absorbing water from the municipal tap water network, which will affect other people's domestic water use and cause pressure imbalance. It is necessary to use tanks equipped with non-negative pressure equipment. Non-negative pressure tanks are all closed, and it is not easy to clean the internal dirt and observe the internal water level control. If there is a slight problem, all pipelines must be removed, which will affect domestic water use over time. Over time, the accumulation of easily corrosive sediments will affect water quality and safety of use. The non-negative pressure water supply tank is the core part of the standard non-negative pressure unit. After the commonly used tanks are welded from the outside, they are closed structures. The inside cannot be cleaned, polished, and polished, which causes a lot of welding slag to remain, and subsequent scale condenses inside, which poses a hidden danger to the later sanitary water use and tank safety, and it is very inconvenient to install instruments inside.
