Description
Affiliated technical field
The utility model discloses a kind of second pressure water supply device that directly links to each other with water supply pipe, belong to the tap water supply technical field.
Background technology
Traditional tap water second pressure water supply device, its pressurized tank water supply unit volume is huge, regulates output and only accounts for 1/3 of tank body, and taking up room also wastes a large amount of steel greatly.And existing general variable frequency water supply unit must supportingly have underground tank or ground upper water box and underground tank and add negative-pressure cup during work, and its shortcoming is that floor space is bigger, the cost height.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that overcomes prior art, provide a kind of volume little, do not need supporting construction underground tank or ground upper water box and underground tank to add the associated mode automatic Regulation frequency conversion water supply facility of negative-pressure cup.
Technical characterictic of the present utility model is structurally to adopt integrated pattern, take into water and the control of water outlet bidirectional modulation, the bailing pipe of water supply installation directly is connected with water supply pipe, by self-con-tained unit its pressure change monitoring is avoided forming negative pressure to guarantee the water supply pipe operate as normal in control, self-con-tained unit can also be regulated to guarantee user's water user's pressure of supply water.
Below introduce structure of the present utility model: a kind of associated mode automatic Regulation frequency conversion water supply facility, comprise and detect control module, variable frequency control cabinet, water pump formation, its feature is at the buffering regulating tank that has directly to be connected with the tap water supply pipeline, and pump outlet connects control valve successively, shunt valve is connected with the buffering regulating tank; Pump intake connects control valve successively, trunk line is connected with the buffering regulating tank; Pump outlet and buffering regulating tank are equipped with pressure sensor respectively and are connected with the detection control module; The buffering regulating tank has the interface that is connected with the tap water supply pipeline.
During the utility model work, the low pressure tap water of tap water supply pipeline enters water pump by the buffering regulating tank, sensor detected pressures on the buffering regulating tank, send working signal to detecting control module, control drives the variable frequency control cabinet and drives water pump to user's water supply of pressurizeing, and according to the size of pump outlet water supply volume, the signal that is sent by pressure sensor is regulated the rotating speed of water pump automatically; When the excessive water of user takes place when, when will producing negative pressure, the water supply pipe insufficient water then sends the signal controlling pump rotary speed by the pressure sensor in the buffering regulating tank, decrease the quantity of exports to guarantee that water supply pipe does not form negative pressure; When tap water pressure was higher than the unit operating pressure, unit quit work automatically, was supplied water to the user by bypass pipe.
The utility model has the advantages that compact conformation, volume are little, control is reliable, automaticity is high.Can not cause Running-water Company's pipeline to produce negative pressure, and influence the normal operation of whole water supply network.Be mainly used in the user of various hydraulic pressure deficiencies, be particularly suitable for occupying a narrow space and build the user of pond or water tank.
Description of drawings
Accompanying drawing 1 is a horizontal type structure schematic diagram of the present utility model, and accompanying drawing 2 is vertical views of Fig. 1.Accompanying drawing 3 is vertical structure schematic diagrames of the present utility model, and accompanying drawing 4 is left views of Fig. 3.Among the figure: 1 buffering regulating tank, 2 water pumps, 3 pressure sensors, 4 pressure sensors, 5 variable frequency control cabinets, 6 bypass pipes, 7 breather valves, 8 blowoff valves.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further: a kind of associated mode automatic Regulation frequency conversion water supply facility, comprise and detect control module, variable frequency control cabinet 5, water pump 2 formations, its feature is at the buffering regulating tank 1 that has directly to be connected with the tap water supply pipeline, and water pump 2 delivery ports connect control valve successively, shunt valve 6 is connected with buffering regulating tank 1; Pump intake connects control valve successively, trunk line is connected with buffering regulating tank 1; Water pump 2 delivery ports and buffering regulating tank 1 are equipped with pressure sensor 3,4 respectively and are connected with the detection control module; Buffering regulating tank 1 has the interface that is connected with the tap water supply pipeline.
Working properly in order to guarantee to cushion regulating tank, breather valve 7 is equipped with on buffering regulating tank 1 top, and blowoff valve 8 is equipped with in the bottom.
Buffering regulating tank described in the utility model is airtight pressure vessel, and is vertical or horizontal, and its volume and regulating effect are in direct ratio.
Detection control module described in the utility model mainly is made up of programmable logic controller (PLC) (PLC), detects control module and connects the formation control loop with the variable frequency control cabinet.
Pressure sensor described in the utility model can adopt the analog pressure signal sensor.
Operational factor behind elder generation's setting pump makes the requirement of satisfying the tap water main of not finding time after equipment installs, and switches on, and then the preceding operational factor of setting pump, makes it satisfy the requirement of user's pressure, formally starts water pump again.When parameter satisfies job requirement behind the pump, by operational factor before the PLC testing pump, when not reaching the outlet setting pressure, water pump starts at once, and pressure of supply water is controlled on the setting pressure parameter, in case parameter is lower than setting value behind the pump, PLC moves to guarantee the tap water main of not finding time with parameter behind the pump immediately.
