Water main, system flowback house steward, each water main, the main that respectively flows back, water inlet decompression venting valve, the special water nozzle of direct drinking, stream
Amount balanced valve, backflow decompression venting valve, backflow preventer, described system water supply house steward and each water main, respectively backflow main,
System flowback house steward is sequentially connected；It is sequentially connected on wherein each water main into water decompression venting valve, the special water nozzle of direct drinking, respectively
Flow balance valve, backflow decompression venting valve, backflow preventer are sequentially connected on backflow main；The special water nozzle of direct drinking is every
At least provided with one on individual water main.
Preferably, described system water supply house steward and system flowback house steward are set along constructure ground or underground, described each
It is arranged in parallel between water main and each backflow main.
The beneficial effects of the utility model embody a concentrated reflection of, and supply water stable and simple in construction, easy to implement, can effectively drop
Low construction cost.It is in particular in, each water main origin or beginning of system sets water inlet decompression venting valve, it is ensured that each water main water
The stabilization of pressure, reduce pipe network cost and operating cost；Each backflow main end sets flow balance valve, backflow decompression venting valve successively
And backflow preventer, wherein flow balance valve connect with backflow pressure-reducing valve, it is ensured that the pressure of return water of each water main and backflow
The pressure of house steward is basically identical, and backflow preventer can be avoided because of when the water supply of other water supply buildings of system or return pressure change pairs
This water supply building has an impact；It is balanced pipe network water pressure simultaneously, between each water main of water supply network and each backflow main simultaneously
Connection is set, and so when system works, is advantageous to pipe network water, hydraulic pressure before reduction pumping plant, is improved pipe network operation condition, and reduce
Water delivery energy consumption cost.Compared with prior art, this water system have technical measures it is clear and definite, it is easy to implement, easy to maintenance,
The advantages such as implementation result is good, construction cost is low.
Brief description of the drawings
Fig. 1 is direct-drinking water pipeline system structural representation.
Embodiment
With reference to Fig. 1, the utility model is described in further detail.
As shown in figure 1, the utility model includes piped direct-drinking water for return pipe net and piped direct-drinking water disinfection system, pipeline
Direct drinking includes system water supply house steward 1, system flowback house steward 2 for return pipe net, each water main 11, each backflow main 12, entered
The special water nozzle 5 of water decompression venting valve 4, direct drinking, flow balance valve 8, backflow decompression venting valve 9, backflow preventer 10；System supplies
Supply mains 1 is sequentially connected with each water main 11, each backflow main 12, system flowback house steward 2；Connect successively on each water main 11
The special water nozzle 5 of water decompression venting valve 4, direct drinking is tapped into, the wherein special water nozzle 5 of direct drinking is at least set on each water main 11
Put one；Flow balance valve 8, backflow decompression venting valve 9, backflow preventer 10 are sequentially connected on each backflow main 12.
Water inlet decompression venting valve 4 is set in each origin or beginning of water main 11, it is ensured that stabilization, the drop of each hydraulic pressure of water main 11
Low pipe network cost and operating cost.The Flow-rate adjustment result of flow balance valve 8 can meet two conditions, first, each supply water of control is done
The return flow of pipe 11, ensure reasonable distribution of the system water supply total amount between each water main 11, second, making system water supply pump not
