The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of no negative-pressure pipeline container water storage device is provided, and the running water pipe that is serially connected in any insufficient pressure and water shortage is online, solves the problem of hydraulic pressure and water shortage, and can be embedded in undergroundly, save spatial surface.
For solving above-mentioned task, the utility model does not have the negative-pressure pipeline container and holds water supply facilities and be made of device in water tank, submersible pump, conduction pipe, conduit pipe and protective housing and the case, submersible pump places the conduction pipe in the water tank, the water supply facilities device of water tank outside concentrates in the protective housing, protective housing is above water tank, seamless link between tank wall and the water tank, making equipment is an overall structure.Pressure sensor is passed to switch board with signal when tap water hydraulic is not enough, and normal pressure is kept in the work of switch board instruction submersible pump; When the tap water quantity not sufficient, submersible pump institute water requirement provides adjusting by water tank, guarantees user's water.
The utility model does not have the negative-pressure pipeline container and holds water supply facilities, submersible pump is built in the water tank, protective housing and water tank seamless link, become an overall structure, compact conformation, so this equipment can be embedded in underground, the rain-proof cover of only exposing protective housing on the ground, take table space tinily, do not have noise and water clock, the investment of having avoided building a house.This equipment not only can solve the water supply problem of pipeline hydraulic pressure when not enough, and can also solve the water supply problem of water flow of pipeline when not enough.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
No negative-pressure pipeline container shown in the drawings holds water supply facilities, is made of device in water tank 23, inlet channel 8, water delivery total pipeline 21, submersible pump 4, conduction pipe 2, conduit pipe 1 and protective housing 20 and the case.Water tank 23 is the seal-off pressure container, the water inlet pipe mouth of tap water inlet channel 8 is introduced its inner and upper, tap water flows in the water tank 23 by inlet channel 8, can produce pressure when holding full water in the water tank 23, when the pressure of tap water itself meets or exceeds the setting value of the pressure sensor 18 that is communicated with outfall sewer road 21, submersible pump 4 is not worked, and the water inlet 24 of tap water by submersible pump 4 enters water-supply-pipe 5 and enter user pipe through water delivery total pipeline 21 again; When tap water pressure during less than the setting value of pressure sensor 18, submersible pump 4 is started working, to keep the setting value of pressure sensor 18; When the inflow of tap water inlet channel 8 can not satisfy water supply requirement, the water requirement of submersible pump 4 provides adjusting by water tank 23, water level in the water tank 23 will descend, ball float in the negative pressure preventer 14 falls, this moment, water tank 23 was connected state with the external world, air enters in the water tank 23, can not make water pipe 23 produce negative pressure, when drawdown during to position that water level controller 7 sets, submersible pump 4 spreads out of instruction by switch board 10 and quits work, when water level returned to the position that sets, submersible pump 4 was reworked.
Submersible pump 4 is built in the water tank 23, be connected with water-supply-pipe 5, water-supply-pipe 5 passes the closed hole 16 of water tank 23, be tightly connected with the blind flange of closed hole 16 and as stress point, submersible pump 4 is suspended in conduction pipe 2 and the water tank 23, and submersible pump 4 does not contact with the tube wall of conduction pipe 2.Water pump cable 6 passes the closed hole blind flange and the sealing back is connected with switch board.
Take out the 22 upper ends sealing of dirty pipe, the lower end is provided with bottom valve, enters conduit pipe 2 inner bottom parts after passing the blind flange of closed hole 16 and sealing, opens the upper end seal cover in the time of need taking out dirt and connects and take out dirty pump and get final product.
Water level controller 7 enters in the water tank 23 by closed hole 16, and the blind flange of its control line and closed hole 16 is tightly connected, and is connected with switch board 10.
Conduit pipe 1 one ends communicate with water tank 23 bottoms, one end communicates with conduction pipe 2 bottoms, the conduction pipe 2 baffle lids 3 that are stamped suitable for reading, have into pump hole on the baffle lid 3, submersible pump 4 enters conduction pipe 2 inside by entering the pump hole, and the water inlet 24 of submersible pump 4 is lower than baffle lid 3, after placing like this, tap water in the water tank 23 can not be from conduction pipe 2 inside that enter suitable for reading of conduction pipe 2, and can only enter the bottom of conduction pipe 2 by conduit pipe 1, make current reduce the motor temperature of submersible pump 4.
Negative pressure preventer 14 communicates with water tank 23 by gate valve 15 above water tank 23, when negative pressure preventer 14 breaks down, does not cause tap water to flow out but closing gate valve 15 keeps in repair.
Protective housing 20 is positioned at the top of water tank 23, seamless link between tank wall and the water tank 23, protective housing 20 is divided into electric control chamber and waterproof compartment by water-stop sheet 12, be provided with manhole 17, closed hole 16, negative pressure preventer 14, water level controller 7, pressure sensor 18 and water delivery pipe valve etc. in the waterproof compartment, this chamber is provided with overflow pipe 19, so that equipment draining in time when leaking; Electric control chamber is provided with switch board 10.Water-stop sheet 12 its excess-three limit and protective housing 20 except that the top are tightly connected, and its plate face is provided with air entraining pipe 13, and the height of overflow pipe 19 should be lower than the suitable for reading of water-stop sheet 12 tops and air entraining pipe 13, and tap water enters electric control chamber when preventing that equipment from leaking.Protective housing 20 is covered by rain-proof cover 9, is provided with exhaust plant 11 in electric control chamber one side on the rain-proof cover 9, so that electric control chamber is aeration-cooling.The shape of rain-proof cover 9 and protective housing 20 can be varied, can be made into individual layer or bilayer.
Electric control chamber inner control cabinet 10 is the constant pressure water supply switch board, and it is outer to be connected with power supply, interiorly is connected with the control line of water pump cable 6, water level controller 7 and the automatically controlled facilities such as holding wire of pressure sensor 18.
