Description

Utilize the secondary booster water supply facilities of city planting ductwork overbottom pressure

Technical field

The utility model relates to a kind of water supply facilities, relates in particular to a kind of secondary booster water supply facilities that utilizes the city planting ductwork overbottom pressure.

Background technology

In the water supply facilities like product that utilizes city planting ductwork overbottom pressure secondary booster, all forming at present by water inlet pipe, adjusting water pot, booster water pump, negative pressure arrester, connecting line gate valve, flap valve, electro connecting pressure gauge, pressure sensor etc.How the water inlet pipe and the outlet pipe of equipment separate, also have bypass pipe, pipeline complexity.

Summary of the invention

The purpose of this utility model is: provide a kind of and can utilize municipal tap water pipe network overbottom pressure, simple, the intelligent control of compact equipment, pipeline avoids producing the secondary booster water supply facilities of negative pressure.

The utility model is realized by following scheme: comprise water inlet pipe, regulate water pot, water level controller, electro connecting pressure gauge, electromagnetic valve, the supply-water pump unit, variable frequency control cabinet and water main), regulate electromagnetic valve and the electro connecting pressure gauge of eliminating negative pressure is housed on the water pot, they receive the pressure signal opens solenoid valve by switch board, to avoid negative pressure to produce and exhaust during hypertonia, it is characterized in that: also comprise the suction water pipe threeway, cyclic balance is regulated water pipe, water inlet pipe also enters the adjusting water pot in the municipal tap water in the suction of supply-water pump unit, regulate that standby adjusting increase-volume is equipped with in the water pot bottom or to the pond, the tube connector threeway of case, water pump assembly after the suction water pipe suction supercharging by exit of pump through flap valve, gate valve is delivered to the user to the water main, regulate in the water pot tank body water level controller is housed, in order to the startup and the low water stage pump trip of control of pump unit, the cyclic balance adjusting water pipe that is picked out by outfall sewer is equipped with on top.

The utility model also is provided with the sensor of controlled pressure.

Water level controller described in the utility model is arranged at regulates water pot tank body middle and lower part.

The utility model supercharging equipment had both utilized municipal tap water pipe network overbottom pressure, and can avoid negative pressure again, do not rob water, not influence near the water supply of periphery with aquatic products, so it has following advantage:

1, reduced investment, instant effect, can not build pond, water tank, pump house, reduce investment outlay more than 50%;

2, keep original municipal tap water water quality, guarantee non-secondary pollution; Save sterilization, cleaned the expense of pond link;

3, compact equipment, pipeline is simple, installation is convenient;

4, intelligent control can accomplish that how much pressure lacks what are mended, and can avoid producing negative pressure, municipal water supply is not had influence, autostop when anhydrous.

Description of drawings

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is Fig. 1 vertical view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

Comprise water inlet pipe 2, adjusting water pot 3, water level controller 4, electro connecting pressure gauge 5, electromagnetic valve 6, suction water pipe threeway 7, suction distribution pipe 8, water pump assembly 9, cyclic balance adjusting water pipe 10, variable frequency control cabinet 11, pressure sensor 12 and water main 13.Press water in the city planting ductwork 1 enters by water inlet pipe 2 and regulates water pot 3; regulating water pot 3 tank bodies middle part is equipped with water level controller 4 and shuts down in order to the control priming level with when anhydrous; electro connecting pressure gauge 5 and electromagnetic valve 6 controls are housed on adjusting water pot 3 tank decks avoid the generation of negative pressure; one circulation adjusting water pipe 10 is housed on outfall sewer 13 passes to bottom in the jar from tank deck top; water pump assembly 9 draws water from suction distribution pipe 8 and delivers to the user through gate valve, flap valve, outfall sewer, sensor 12 also is housed with transmission controlled pressure value signal on the house steward.The switch of electric elements is by switch board 11 controls.

Operating principle of the present utility model is:

After the press water of city planting ductwork enters the adjusting water pot, water level constantly rises in jar, when water level rises to the upper limit water level of water level controller, and one of starting mode of pump, the water that water pipe is regulated in the circulation of front end outfall sewer at this moment is back in the adjusting water pot, and the water main send pressure (hydraulic) water to the user simultaneously.When the flow of first water pump, when pressure can satisfy water, this pump was with regard to frequency conversion or power frequency work; When the power frequency flow can not satisfy water, pressure can descend, and the sensor received signal reaches switch board again, after judging, switch board sends instruction, the operation of devoting oneself to work automatically of second water pump, first power frequency work at this moment, the pressure operation that water supply network sets is kept in second frequency conversion work.Otherwise when reducing gradually with discharge, switch board can stop a water pump operation again automatically, and another continues power frequency or frequency conversion work.When night, municipal ductwork pressure was increased to the force value of setting, switch board received this signal, can instruct two pumps all to quit work, and directly delivered to the user by municipal administration pipe water.When municipal ductwork pressure dropped to setup pressure value, equipment can start water pump again, and the output constant pressure supplies water.When municipal ductwork pressure is reduced to 0.01Mpa when not producing negative pressure as yet; switch board receives electric contact table signal; send instruction; electromagnetic valve is opened; air enters the adjusting water pot; avoid negative pressure to produce; as regulate and still have water in the water pot, and on the water level lower control limit, water pump assembly still works on; not enough up to water inlet; when water level controller was reduced to lower limit, water pump just can be shut down, and avoided the anhydrous idle running of water pump and damaged; when city planting ductwork recovered feedwater and makes water level controller reach priming level, equipment began to start operation again.
