Description

Technical Field

[0001] The utility model relates to the technical field of double-pass water supply devices, in particular to a double-pass water supply device for non-negative pressure water supply equipment. Background Art

[0002] Non-negative pressure water supply equipment is a pressurized water supply unit, which is often connected to the municipal water supply pipeline. It is a secondary pressurized water supply equipment that is connected in series and superimposed on the residual pressure of the municipal pipeline network to ensure that the pressure of the municipal pipeline network is not less than the set protection pressure (the set pressure must be higher than the pressure demand of the direct supply area of ​​the community, generally not less than 1.2Kg). In the process of community construction, in order to ensure the water supply of high floors, non-negative pressure water supply equipment is required. Combined with the water supply device, the water supply pressure can be guaranteed and it is convenient for adjustment and use. The relevant technology currently circulating in the market is double-chamber water supply. Its working principle is to build a diaphragm in the stabilizing tank to divide the stabilizing tank into two independent chambers. The two chambers of the stabilizing tank are connected to the tap water network respectively, one part is connected to the booster pump through the pipeline, and then connected to the user, and the other part is directly connected to the user. When the user's water demand can be met, the equipment directly supplies water to the user through the stabilizing tank. When the user's water demand cannot be met, the booster pump is started through another chamber of the stabilizing tank to supply water to the user. As we know, in non-negative pressure water supply equipment, the size of the turbulence tank plays a key role in non-negative pressure water supply, and dividing the turbulence tank into two chambers actually reduces the size of the turbulence tank. The disadvantage of this is that to achieve the same technical function, a larger turbulence tank is required, and the production and cost of the turbulence tank will increase.

[0003] When supplying water, the existing two-way water supply device generates water shock waves due to the inertia of the pressurized water flow, forming a water hammer phenomenon and causing vibration of the water pipe. Under long-term influence, the water pipe will rupture and cannot supply water normally. After long-term operation, scale will appear in the water supply barrel and the water supply pipe. If it is not cleaned in time, it will affect the water quality. In this regard, in order to solve this technical problem, the present application proposes a two-way water supply device for non-negative pressure water supply equipment. Utility Model Content
