The utility model object realizes being completed by following technical scheme:
A kind of network pressure superposition water supply system, at least comprise direct-furnish district supply channel and low-pressure charging district supply channel, the supply channel one end in described direct-furnish district is communicated with city planting ductwork, the other end is communicated with direct-furnish district water end, it is characterized in that: the described direct-furnish district supply channel at described city planting ductwork interface rear is provided with normally open type magnetic valve, the described direct-furnish district supply channel at described normally open type magnetic valve rear forms in parallel with described low-pressure charging district supply channel.
Described low-pressure charging district supply channel at least comprises steady-flow tank, at least two-way branch line, and wherein a road branch line is communicated with the described direct-furnish district supply channel at described normally open type magnetic valve rear, and another road branch line is communicated with low district water end.
Along the water supply direction of described low-pressure charging district supply channel, described branch line is disposed with import gate valve, import connecting hose, low district booster pump, outlet connecting hose, outlet gate valve, exports back valve.
Normally closed solenoid valve, pressure signal sensor, electric shock point pressure meter is provided with between the described direct-furnish district supply channel at described branch line and described normally open type magnetic valve rear.
The water inlet of described steady-flow tank forms with described city planting ductwork and is communicated with.
Described steady-flow tank is provided with vacuum suppresser.
The utility model has the advantages that: with water low ebb time, the electromagnetic valve of direct-furnish water section is in normally open, direct-furnish district is directly supplied water by city planting ductwork with water, and the energy of water pump is effectively controlled.In water use peak period, when municipal ductwork pressure cannot meet direct-furnish district pressure, close the city planting ductwork normally open solenoid valve in direct-furnish district, open the ability electromagnetic valve of low-pressure charging unit, direct-furnish district is supplied water and lists low-pressure secondary pressurized water supply scope in, thus while ensure that direct-furnish district water, can not the pressure of supply water in Zeng Hui low-pressure charging district.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present utility model.
Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As shown in Figure 1, mark 1-21 in figure to be expressed as: direct-furnish district water end 1, direct-furnish district pipe network 2, normally closed solenoid valve 3, normally open type magnetic valve 4, city planting ductwork interface 5, outlet connecting hose 6, outlet gate valve 7, export back valve 8, import gate valve 9, import connecting hose 10, low district booster pump 11, low district's water supply header 12, steady-flow tank delivery port 13, liquid level signal probe 14, steady-flow tank 15, steady-flow tank water inlet 16, inlet check valve 17, low district water end 18, vacuum suppresser 19, pressure signal sensor 20, electric shock point pressure meter 21.
Embodiment: as shown in Figure 1, the network pressure superposition water supply system in the present embodiment comprises direct-furnish district pipe network 2 and low-pressure charging district supply channel, and direct-furnish district pipe network 2 is for supplying water for direct-furnish district water end 1, and low-pressure charging district supply channel is that low district water end 18 supplies water.
As shown in Figure 1, supply channel one end of direct-furnish district pipe network 2 is communicated with city planting ductwork by city planting ductwork interface 5, the other end connects direct-furnish district water end 1, its pipeline is provided with normally open type magnetic valve 4, normally open type magnetic valve 4 normality is opened, namely keep city planting ductwork interface 5 to be communicated with between direct-furnish district water end 1, complete direct-furnish district and supply water.
As shown in Figure 1, the direct-furnish district supply channel at normally open type magnetic valve 4 rear forms in parallel with low-pressure charging district supply channel, connecting pipeline is between the two provided with normally closed solenoid valve 3, normally closed solenoid valve 3 normality is closed, only in the water use peak phase, just open when the source pressure of coming from city planting ductwork interface 5 is not enough to directly deliver to direct-furnish district water end 1, utilize low district's water supply pressurized equipment, namely by low district booster pump 11, the object that direct-furnish district supplies water is ensured.
Low-pressure charging district supply channel comprises steady-flow tank 15, and the steady-flow tank water inlet 16 at steady-flow tank 15 top is communicated with city planting ductwork through city planting ductwork interface 5, the pipeline between steady-flow tank water inlet 16 and city planting ductwork is provided with the inlet check valve 17 for preventing aqueous reflux.Steady-flow tank delivery port 13 bottom steady-flow tank 15 is communicated with low district's water supply header 12, and low district's water supply header 12 is divided into two branch lines, and wherein a road is that low district water end 18 supplies water, and another road is that direct-furnish district water end 1 supplies water.Two branch lines are disposed with respectively secondary to water inlet gate valve 9, import connecting hose 10, low district booster pump 11, outlet connecting hose 6, outlet gate valve 7, outlet non-return valve 8 along its water supply direction, namely completed the supercharging at water source by low district booster pump 11, ensure that water source has enough pressure to be fed to two water end places respectively.
The present embodiment is when specifically using: (1) is with water low ebb period, the direct-furnish district water end 1 that the water source of city planting ductwork interface 5 directly enters direct-furnish district 2 through normally open type magnetic valve 4 makes normal water supply, now normally closed solenoid valve 3 is closed, low district supplies water and between direct-furnish water, nothing contacts, and carries corresponding water supply function separately.
(2) in water use peak period, the source pressure of coming from city planting ductwork interface 5 is not enough to directly deliver to direct-furnish district water end 1, now normally open solenoid valve 4 cuts out, the current of municipal water supply interface 5 must enter steady-flow tank 15 through inlet check valve 17, enter low district's water supply header 12 through steady-flow tank delivery port 13 again, then enter in low district water end 18 through water inlet gate valve 9, import connecting hose 10, low district booster pump 11, outlet connecting hose 6, outlet gate valve 7, outlet non-return valve 8 successively.Now current divide two-way to carry out, one normally closed solenoid valve 3 of water end 18, tunnel, direct Jin Di district, tunnel through having opened enters direct-furnish district water end 1, and then reaches indirectly by low district's water supply pressurized equipment, namely by low district booster pump 11, the object that direct-furnish district supplies water is ensured.
