In the water supply unit of existing design, when municipal ductwork pressure reduces underfed, utilize pump operation to increase pressure, long running can cause the minimizing in the life-span of water pump.When city planting ductwork is cut off the water supply, the water in steady-flow tank can only be used to supplement, discharge is not very large, affecting with water precocity user.
utility model content:
The purpose of this utility model provides a kind of non-negative pressure water-supply installation with fluidic device for above-mentioned Problems existing, can ensure user's pipe network water when municipal ductwork pressure underfed.
Above-mentioned object is realized by following technical scheme:
With the non-negative pressure water-supply installation of fluidic device, comprise the water tank and steady-flow tank that are connected with city planting ductwork respectively, described water tank connects water pump assembly, the outlet pipe of described water pump assembly is connected with the supervisor of tee piece, the arm one of described tee piece connects user pipe by straight pipe, the arm two of described tee piece connects the suction side of ejector, the outlet conduit of described steady-flow tank is connected the diffuser pipe of ejector by motor operated valve, the ejection end of described ejector connects user pipe, described straight pipe, user pipe is respectively arranged with pressure monitoring device, described arm one and described arm two are respectively arranged with electromagnetic valve.
The described non-negative pressure water-supply installation with fluidic device, also includes switch board, and described pressure monitoring device, water pump assembly are all connected with switch board with described electromagnetic valve, motor operated valve.
The described non-negative pressure water-supply installation with fluidic device, described ejector adopts Venturi tube ejector.
The described non-negative pressure water-supply installation with fluidic device, the outlet pipe of described water pump assembly is also provided with pressure monitoring device.
Beneficial effect:
The utility model water source when municipal ductwork pressure is stablized is directly user's pipe network water supply after water pump assembly pressurization, when municipal administration pressure transient, double-direction control mechanism controls current are through fluidic device, the flow needed for compensation opened by motor operated valve simultaneously, ensures flow and the pressure of user's pipe network.

detailed description of the invention:
Embodiment 1:
As shown in Figure 1, the non-negative pressure water-supply installation with fluidic device of the present embodiment, comprise the water tank 1 and steady-flow tank 2 that are connected with city planting ductwork respectively, described water tank connects water pump assembly 3, the outlet pipe 4 of described water pump assembly is connected with the supervisor 5 of tee piece, the arm 1 of described tee piece connects user pipe 8 by straight pipe 7, the arm 29 of described tee piece connects the suction side 10 of ejector, the outlet conduit of described steady-flow tank is connected the diffuser pipe 12 of ejector by motor operated valve 11, the ejection end 13 of described ejector connects user pipe, described straight pipe is provided with pressure monitoring device 14, described user pipe is provided with pressure monitoring device 15, described arm one is provided with electromagnetic valve 16, described arm two is provided with electromagnetic valve 17.
After the present embodiment adopts technique scheme, in the process of normal water supply, motor operated valve 11 and electromagnetic valve 17 are closed, , electromagnetic valve 16 is opened, municipal network water supply directly supplies water water tank, water in water tank flows through the arm one of tee piece by water pump assembly, then directly user is supplied by straight pipe, when the water yield in water tank and hydraulic pressure deficiency, it is too low that pressure monitoring device 14 on straight pipe monitors hydraulic pressure, so close the electromagnetic valve 16 on arm one, open the electromagnetic valve 17 on motor operated valve 11 and arm two simultaneously, water in arm one enters the suction side of ejector, the intake place of ejector is made to produce negative pressure appearance, and the water in steady-flow tank enters the diffuser pipe of ejector after the outlet pipe of steady-flow tank flows through motor operated valve, supply user pipe is flowed out from the ejection end of ejector after water that is last and suction side mixes, ensure flow and the pressure of user's pipe network.
Embodiment 2:
The difference of the present embodiment and embodiment 1 is: the described non-negative pressure water-supply installation with fluidic device, also includes switch board 18, and described pressure monitoring device, water pump assembly are all connected with switch board with described electromagnetic valve, motor operated valve.Can by the controlled condition writing controller that presets, make to control convenient and accurate by the switch of switch board by-pass valve control.
Embodiment 3:
The difference of the present embodiment and embodiment 1 or embodiment 2 is, described ejector adopts Venturi tube ejector.
Embodiment 4:
The difference of the present embodiment and above-described embodiment is: the described non-negative pressure water-supply installation with fluidic device, the outlet pipe of described water pump assembly is also provided with pressure monitoring device 19.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-described embodiment, also comprises and is equal to by above technical characteristic the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
