Abstract

The utility model provides a non-negative-pressure pipe direct drinking water supply system, which comprises a steady-flow compensator, a vacuum suppressor, an ultraviolet sterilizer, a water pump, an electromagnetic valve and a control cabinet. A direct drinking water supply pipe is sequentially connected with a backflow preventer, the steady-flow compensator, the ultraviolet sterilizer and the water pump and then connected with a user water supply pipe network. A user return water pipe network is arranged at the elevation same as the user water supply pipe network. The user return water pipe network is connected with the backflow preventer of the direct drinking water supply pipe. The electromagnetic valve and a check valve are arranged on the user return water pipe network. The utility model has the advantages that the steady-flow compensator and the vacuum suppressor are adopted to directly connect the water pump with the direct drinking water supply pipe for pressurization, the user return water pipe network is arranged at the elevation same as the user water supply pipe network, the fresh and healthy direct drinking water in the user water supply pipe network is effectively ensured, the system is simple, the arrangement is flexible, the occupied area is small, the investment is saved, the operation is energy-saving, the installation and the maintenance are convenient, the pressurized pipe direct drinking water supply system can be widely used.

Description

No negative-pressure pipeline direct drinking water supply system
1, technical field
The utility model relates to a kind of piped direct-drinking water pressurizing feedwater system, especially a kind of no negative-pressure pipeline direct drinking water supply system.
2, background technology
The piped direct-drinking water of the highrise building of prior art is supplied to water system to adopt independently piped direct-drinking water treating stations mostly, and independently direct drinking machine room and direct drinking treatment facility need be set, and equipment takes up an area of big, attended operation trouble, and first cost height; Also there are the part residential quarters adopt to concentrate or regional piped direct-drinking water is supplied to water system, but because the use of each building height and subregion situation are not quite similar, have phenomenons such as low district user pipe network pressure-bearing height or decompression energy dissipation, employing is simultaneously concentrated or regional piped direct-drinking water is supplied to the feed-line of water system longer, and the water quality of terminal temperature difference is more difficult to get guarantee.
3, utility model content
In view of above-mentioned the deficiencies in the prior art, the utility model provide a kind of reasonable in design, simple in structure, take up an area of little, reduced investment, convenient operating maintenance and can directly be concatenated into the no negative-pressure pipeline direct drinking water supply system of direct drinking supply pipe network.
The technical scheme that its technical problem that solves the utility model adopts is: no negative-pressure pipeline direct drinking water supply system is by steady flow compensator, vacuum suppresser, ultraviolet sterilizer, water pump, electromagnetic valve and switch board are formed, the direct drinking feedwater piping connects backflow preventer successively, steady flow compensator, ultraviolet sterilizer, connect user's water supply network behind the water pump again, be provided with user's return pipe net with user's water supply network with journey, and after user's return pipe net being received the backflow preventer of direct drinking feedwater piping, on user's return pipe net, be provided with simultaneously electromagnetic valve and flap valve, on the current stabilization hutch water device, be equiped with vacuum suppresser and intake pressure sensor, on the user's water supply network behind the water pump, be provided with the pressure of supply water sensor, vacuum suppresser, ultraviolet sterilizer, water pump, electromagnetic valve, intake pressure sensor and pressure of supply water sensor are wired to switch board respectively.
Vacuum suppresser and steady flow compensator realize that water pump does not produce negative pressure with direct serial connection of direct drinking feedwater piping, intermediate water tank need not be set during the water pump pressurization, not only can utilize the supported pressure on the direct drinking feedwater piping, save energy consumption, and avoid the pollution section of intermediate water tank.
The beneficial effects of the utility model are, when adopting steady flow compensator and vacuum to suppress to realize that water pump directly is connected in series pressurization with the direct drinking feedwater piping, be provided with user's return pipe net with user's water supply network with journey, guaranteed fresh, the health of direct drinking effectively, and system is simple, is provided with flexibly at user's water supply network, take up an area of few, reduced investment, energy saving in running, convenient for installation and maintenance.
