Description of reference numerals: 1, end socket, 2, cylindrical shell, 3, supporting leg, 4, blowoff valve, 5, delivery port, 6, safety valve, 7, content gauge, 8, pressure sensor, 9, water inlet, 10, negative pressure canceller, 11, water pump.
The specific embodiment
With reference to 1 pair of flow regulator of the present utility model of Figure of description, be described in detail below.
Flow regulator of the present utility model, its structure comprises cylindrical shell 2, negative pressure canceller 10 and content gauge 7, described negative pressure canceller 10 is arranged on the top of cylindrical shell 2, play the effect that negative pressure is eliminated, content gauge 7 is arranged on the inner chamber bottom of cylindrical shell 2, the two ends, left and right of described cylindrical shell 2 are respectively arranged with end socket 1, the top of described cylindrical shell 2 is also provided with water inlet 9 and pressure sensor 8, water inlet 9 is connected with city planting ductwork, described pressure sensor 8 and cylindrical shell 2 intracavity inter-connections, the bottom of described cylindrical shell 2 is provided with delivery port 5, blowoff valve 4 and safety valve 6, described delivery port 5 is connected with the water sucking mouth of water pump 11, the delivery port of water pump 11 is connected with user's pipe network, described pressure sensor 8, content gauge 7 and water pump 11 are electrically connected to electrical control system respectively.
The bottom of described cylindrical shell 2 is provided with supporting leg 3, and described supporting leg 3 comprises two, is separately positioned on the left and right sides of cylindrical shell 2 bottoms.
Described blowoff valve 4 and safety valve 6 are separately positioned on the left and right sides of delivery port 5.Blowoff valve 4 is for regularly the dirt in cylindrical shell 2 being discharged, and safety valve 6 raises for the pressure in cylindrical shell 2, while surpassing setting, automatically opens, and by the water in discharge cylindrical shell 2, carries out pressure release.
Described cylindrical shell 2, end socket 1, supporting leg 3, blowoff valve 4, safety valve 6, water inlet 9, delivery port 5 and negative pressure canceller 10 are respectively stainless steel and make.
Flow regulator is docked by end socket 1 and cylindrical shell 2 spot welding, by supporting leg 3, supports firm.Tap water enters in flow regulator by water inlet 9, and negative pressure canceller 10 is opened automatically, and the interior air of cylindrical shell 2 is discharged automatically, prevents that negative pressure from producing.After water is full, negative pressure canceller 10 is closed automatically.
When municipal ductwork pressure can meet water requirement, system directly supplies water to user's pipe network.When municipal ductwork pressure can not meet water requirement, the pressure signal in cylindrical shell 2 feeds back signal to electrical control system by pressure sensor 8, controls water pump 11 operations, and according to the big or small self-regulating rotary speed constant pressure water supply of water supply volume.
If the city planting ductwork water yield is greater than pump capacity, system keeps normal water supply; If during water use peak, the water yield of city planting ductwork is less than pump capacity, and the water in flow regulator is water source normal water supply as a supplement.When the interior water level of cylindrical shell 2 drops to designated water level, content gauge 7 is by signal feedback to control system, and water pump 11 autostops, to protect water pump 11.
Except the technical characterictic described in manual, be the known technology of those skilled in the art.
