Description
Technical Field
The invention belongs to the field of secondary water supply equipment, and particularly relates to secondary water supply equipment.
Background
The secondary water supply refers to the unique way that a unit or an individual stores and pressurizes urban public water supply or self-built facility water supply and then supplies the water to users through a pipeline, for high-rise buildings, due to the lack of pressure of municipal water supply pipelines, the municipal water supply is generally pressurized for the second time to enable tap water to reach high-rise and high-rise users for use, and during the secondary water supply, the water is supplied to high floors; in the prior art, the box type non-negative pressure water supply equipment is a practical secondary water supply mode at present, the equipment is provided with a water tank on the basis of the original non-negative pressure water supply equipment, and the maximum supply quantity of the municipal pipe network under the lowest service pressure can still be utilized during the peak period of water consumption. While the user's difference in water usage is compensated by the tank. The volume ratio of the box type non-negative pressure water tank is small, and the occupied area is saved. The smaller the volume of the water tank is, the easier the water inside the water tank is to circulate, and the water quality is fresher. Thereby ensuring the water supply pressure of buildings such as high-rise residential districts, office buildings and the like and ensuring the quality of tap water. At present, a plurality of stainless steel square pressure film combined water tanks are used, and a plurality of tie bars are welded inside the stainless steel square pressure film combined water tanks to ensure that the water tanks can bear enough water pressure. However, in the storage process, because the velocity of flow of water in the water tank is slower, rust in the running water, tiny particle impurity etc. very easily deposit, can breed some germ even, and the influence that the accumulation got off to quality of water is big, because the existence of lacing wire makes the water tank be difficult to wash again, existing belt cleaning device often need shut down the washing among the prior art, and need arrange inside water when wasing, wastes time and energy and influences normal water supply, has very big influence to the secondary water supply.
