Among the figure, 1 current stabilization jar, 2 water inlets, 3 vacuum suppressers, 4 delivery ports, 5 conflux house steward, 6 feed pipes, 7 pressurized tanks, 8 vector water pumps, 9 vector motors, 10 vector converter controllers, 11 pressure sensors, 12 unidirectional stop valves, 13 switch boards.
The specific embodiment
To combine accompanying drawing that the specific embodiment in the utility model is done further explain below.
The pot type vector non-negative pressure water-supply installation that the utility model relates to; Include current stabilization jar 1, said current stabilization jar 1 top is provided with water inlet 2 and vacuum suppresser 3, and the bottom of said current stabilization jar 1 is provided with delivery port 4; Include the house steward 5 of confluxing, feed pipe 6; Pressurized tank 7, vector water pump 8, vector motor 9 and vector converter controller 10, said vector motor 9 is arranged on the vector water pump 8, and vector converter controller 10 is fixed on the vector motor 9; The delivery port 4 of said current stabilization jar 1 is connected with the house steward 5 of confluxing; The water inlet end of said two vector water pumps 8 is connected with the house steward 5 of confluxing respectively, and the water side of two vector water pumps 8 links to each other with feed pipe 6 respectively, and said pressurized tank 7 links to each other with the water side of two vector water pumps 8.
The water side that water inlet 2 places of said current stabilization jar 1 are provided with 11, two vector water pumps 8 of pressure sensor is provided with unidirectional stop valve 12.
Said pressure sensor 11 and vacuum suppresser 3 are electrically connected with vector converter controller 10 through switch board 14 mutually.
Pressurized tank described in the instance of the utility model 7 is a diaphragm type pressurized tank 7; Said pressurized tank 7 is when work, and feed pipe 6 is in the moment of vector water pump 8 start and stop, and pressure increases suddenly in the feed pipe 6; At this time water under high pressure can pour in the pressurized tank 7 at once; Feed pipe 6 internal pressures are maintained on the relatively stable value, and when feed pipe 6 internal pressures reduced suddenly, the water in the pressurized tank 7 flow in the feed pipe 6 from pressurized tank 7 again; Make feed pipe 6 under the effect of pressurized tank 7, be always maintained at metastable state.
In the utility model, water level rises in current stabilization jar 1, and air in the current stabilization jar 1 is discharged through vacuum suppresser 3, and vacuum suppresser 3 is closed during full water; During drawdown, vacuum suppresser 3 is opened, and sucks air through vacuum suppresser 3 in the current stabilization jar 1; Realize the pressure balance in the current stabilization jar 1; Guaranteed the tap water pipe network is not produced negative pressure, the vacuum suppresser 3 in the utility model is a prior art, repeats no more at this.
