A kind of cistern pressure-stabilizing water supply system, as shown in Figure 1, including cistern 1, water pump 2 and water-main for water storage
3, the water in cistern 1 is extracted out using multiple water pumps 2 and then is delivered into water-main 3, water-main 3 and needs to stablize hydraulic pressure
Equipment connection, stable hydraulic pressure is provided for these equipment.
As shown in Fig. 2, cistern 1 be set to bottom surface hereinafter, 1 upper end of cistern have using armored concrete construction it is flat with bottom surface
Neat head cover 12 reduces the floor space of water system, improves to make the place of 1 top of cistern that can also be used
Utilization of area rate.1 upper end side wall of cistern is equipped with the water inlet pipe 11 communicated therewith, and water inlet pipe 11 is connected to cistern 1
One end is equipped with the float switch 111 for being same as opening and closing water inlet pipe 11, and water inlet pipe 11 can be connected to tap water pipe line can also place
Water recovery culvert is connected to, and is 1 amount of makeup water of cistern using tap water and place water, is conserved water.2 water inlet of water pump connects
There are drinking-water pipe 21, the one end of drinking-water pipe 21 far from water pump 2 to extend down into cistern 1, but the bottom of cistern 1 is used for a long time
Portion has impurity deposition, and when drinking-water pipe 21 stretches into 1 bottom of cistern, have impurity sucking makes to influence the normal of water system
With, and when drinking-water pipe 21 is too close to float switch 111, the water inlet of drinking-water pipe 21 is excessively close apart from the water surface, may when drawing water
There is free aspiration to enter, so the water inlet of drinking-water pipe 21 is located at the centre position between 1 bottom of pond of float switch 111 and cistern.
As shown in Figure 1, water pump 2 is electrically connected with the frequency converter 41 of control 2 rotating speed of water pump, frequency converter 41 is electrically connected with controller
4, frequency converter 41 is controlled using controller 4, to control the rotating speed of water pump 2, and then controls the displacement of water pump 2.Water pump 2 is discharged
Mouth is connected to water-main 3, because there are gaps inside water pump 2, does not work in water pump 2 and the hydraulic pressure of its water outlet is more than water inlet
When hydraulic pressure, water can be flowed back to from the gap in water pump 2 in cistern 1, therefore be equipped with only between 2 water outlet of water pump and water-main 3
Valve 22 is returned, the water for flowing back to cistern 1 is reduced, the hydraulic pressure in water-main 3 can be maintained when water pump 2 does not work, and reduce water
The pressure difference between 2 water outlets and water inlet is pumped, reduces load when water pump 2 starts, water pump 2 is made smoothly to start.
As shown in Figure 1, water-main 3 is equipped with the pressure switch 34 that can detect its inside water pressure, pressure switch 34 is set
There are upper limit value and lower limiting value, the ranging from equipment between the upper limit value and lower limiting value provides the pressure limit for stablizing hydraulic pressure, pressure

Water pump 2 processed makes water pump 2 be stopped, and continues to increase to stop hydraulic pressure；When hydraulic pressure is less than lower limiting value in water-main 3, pressure
Switch 34 triggers and so that controller 4 is controlled water pump 2 makes water pump 2 start, will be in water-main 3 to increase the hydraulic pressure in water-main 3
Hydraulic pressure maintain between upper limit value and lower limiting value.
As shown in Figure 1, when multiple equipment uses water simultaneously, water consumption increases, and the hydraulic pressure in water-main 3 is made to be dropped rapidly to
Lower limiting value is hereinafter, in order to maintain the hydraulic pressure in water-main 3, water pump 2 that repeatedly starting and stopping, water pump 2 will produce larger electricity when starting
Stream, frequent start and stop water pump 2 is unfavorable for its long-time service, therefore flow sensor 31 is additionally provided on water-main 3, utilizes flow
Sensor 31 detects the flow in water-main 3, is according to the frequency conversion for controlling water pump 2 by controller 4 with the flow in water-main 3
There is 2 repeatedly starting and stopping of water pump to make the displacement of water pump 2 and the total water consumption of multiple equipment maintain an equal level to reduce in device 41
Situation extends the service life of water pump 2.
Pressure release electromagnetic valve 32 is additionally provided on water-main 3, pressure release electromagnetic valve 32 is electrically connected with pressure switch 34, works as pressure switch
When hydraulic pressure is more than upper limit value in 34 detection water-mains 3, pressure release electromagnetic valve 32 is opened, and is reduced the hydraulic pressure in water-main 3, is worked as water-main
When hydraulic pressure is less than upper limit value in 3, pressure release electromagnetic valve 32 is closed, and hydraulic pressure is made to maintain between upper limit value and lower limiting value, it is therefore prevented that total
Hydraulic pressure is more than upper limit value in water pipe 3, makes voltage regulation result more preferably.The water outlet of pressure release electromagnetic valve 32 is connected with return duct 321, reflux
The one end of pipe 321 far from pressure release electromagnetic valve 32 is connected to cistern 1, and the water that pressure release is flowed out is back in cistern 1, is saved
Water is used, also saves cost.
As shown in Figure 1, water-main 3 is connected with several distributive pipes 33, distributive pipe 33 respectively with the equipment that needs to stablize hydraulic pressure
Connection, distributive pipe 33 are equipped with voltage-stabiliser tube 331, are equipped with catch 332 in voltage-stabiliser tube 331, catch 332 be located at voltage-stabiliser tube 331 into
Play the role of obstructing inlet and outlet between the mouth of a river and water outlet, catch 332 and 331 inner wall of voltage-stabiliser tube there are gap,
Water is flowed into from the water inlet of voltage-stabiliser tube 331, and water outlet is flow to from the gap between 331 madial wall of catch 332 and voltage-stabiliser tube, profit
The flow velocity of flow is reduced or remitted with catch 332, flow velocity fluctuates the shadow to the flow velocity in voltage-stabiliser tube 331 in water-main 3 and distributive pipe 33
Sound is smaller, reduces influence of the flow velocity fluctuation of water to equipment water hydraulic pressure；Between between 331 madial wall of catch 332 and voltage-stabiliser tube
The sectional area of gap is more than the caliber of distributive pipe 33, has further slowed down the flow velocity in voltage-stabiliser tube 331, has further reduced the stream of water
Speed fluctuation is to the equipment influence of water hydraulic pressure.
Specific working mode：Multiple water pumps 2 draw water from cistern 1, then deliver the water water-main 3, using only
Returning valve 22 prevents water to be back in cistern 1 from the water pump 2 of stopping, and water pump 2 and pressure release electromagnetism are controlled using pressure switch 34
Valve 32 detects the flow in water-main 3 to maintain the pressure in water-main 3, using flow sensor 31, controls the row of water pump 2
Water further maintains the hydraulic pressure in water-main 3 to also avoid the repeatedly starting and stopping of water pump 2, increases the service life of water pump 2.
Then it utilizes voltage-stabiliser tube 331 to reduce or remit the flow velocity of water, reduces flow velocity in water-main 3 and distributive pipe 33 and fluctuate to voltage-stabiliser tube 331
In flow velocity influence, the flow velocity to reduce water fluctuates influence to equipment water hydraulic pressure.Water-main 3 carries for multiple equipment
For stable hydraulic pressure, the larger flow generated using multiple water pumps 2 provides abundance while maintaining hydraulic pressure for multiple equipment
Water, and then meet the water source that steady pressure is provided with a water system for multiple equipment.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
