Full-automatic current limiting type negative pressure-free pipe network Pressure-superposed water supply equipment

Abstract

The invention discloses a full-automatic current-limiting non-negative pressure pipe network lamination water-supply device, wherein a pipe network is directly connected in series with a water pump to pressurize and supply water, thereby cancelling a middle process of secondary pollution which is caused by exposition and storing of water bodies of water ponds and water tanks and the like. Under the totally-enclosed environment, the condition of producing negative pressure is eliminated, and the device runs under constrained conditions and does not produce negative pressure, which avoids harmful impact to the pipe network. Even if negative is going to be produced, the marginal state to produce negative pressure can be eliminated, and the dual-function of prevention and elimination can guarantee that water flow state in the pipe network changes steadily and smoothly, and the pipe network runs steadily, and qualified running water is directly supplied to each water-consumed spot. The invention has the outstanding advantages of high energy-saving, high reliability, strong application performance, full-automatic control, and environmental protection.

Description

Technical field: [0001] The invention relates to the technical field of water supply, in particular to a fully automatic flow-limiting non-negative pressure pipe network superimposed pressure water supply equipment, which can be directly connected in series to the pipe network. Background technique: [0002] At present, due to the large coverage area of ​​the water supply pipe network, uneven terrain and more and more high-rise buildings, there are many ways to supply water by secondary pressurization. Qualified drinking water that has been strictly purified, treated and disinfected by the water plant will produce secondary pollution during the process of transportation, storage and secondary pressurization, which will affect the safety of water supply quality. A large number of secondary pollution accidents occurred in the secondary pressurization link, among which, the storage tank and the high level water tank are the main pollution sources. The way of directly installin...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a fully automatic flow-limiting type non-negative pressure pipe network superimposed pressure water supply equipment, which mainly solves the secondary pollution easily caused by the existing water supply equipment and the negative pressure generated during the water supply process. Problems such as elimination after pressure, adverse impact on the pipe network, unstable change of flow state in the pipe network, etc.
