Abstract
The utility model discloses a non-negative pressure permanent flow feed water equipment for high-rise building directly connected with main-water ductwork, including a variable frequency holder, a pressure tank, a pressure sensing device, a pump assembly, a permanent flow tank, a vacuum eliminator and a backflow preventer, characterized in that the permanent flow tank is provided with a vacuum eliminator, the inlet of the permanent flow tank is connected with a negative pressure proof module, the inlet of the negative pressure proof module is connected with backflow preventer and then is connected with a water main, the outlet of the permanent flow tank is connected with the pump assembly, the outlet of the pump assembly is connected with a pressure tank and a pressure sensing device. The utility model adds a negative pressure proof module, a permanent flow tank and a vacuum eliminator at the inlet of the permanent flow tank, connects with the main-water ductwork directly, employs the pressure of the main-water ductwork, reduces pump delivery head and electrical energy consumption of investment, saves the pool, investment and space, avoids potential pollution and spilling water loss in the storage cistern. The utility model provides a negative pressure proof module thereby realizing dual negative pressure protection.
Description
Technical field
The utility model relates to a kind of water supply facilities of the highrise building special use that links to each other with the tap water pipe network, the non-negative pressure stabilized water supply facilities of the highrise building special use that particularly can directly link to each other with the tap water pipe network.
Background technology
Because general water supply facilities can produce negative interaction after directly inserting the tap water pipe network, causes ductwork pressure to descend, and influences peripheral user's water, this way of supplying water generally is unallowed.For addressing this problem, traditional way of supplying water adopts reservoir or water tank to cut off usually and regulates.System constitutes (Fig. 1): frequency conversion tank 21, air pressure tank 22, control valve 23, flap valve 24, pressure sensor 25, main pump 26, float valve 27, main valve 28, attached pump 29, pond (case) 210.This way of supplying water and shortcoming are: the water quality in pond or the water tank is easily polluted and the spilling water loss is arranged; Original tap water pipe network pressure can waste; Investment and occupation of land are long-pending big.Existing also have non-negative pressure stabilized water supply facilities (Fig. 2), and it is composed as follows: frequency conversion tank 31, air pressure tank 32, control valve 33, flap valve 34, pressure sensor 35, main pump 36, main valve 37, backflow preventer 38, attached pump 39, current stabilization jar 310.The shortcoming of this structure is: when the vacuum breaker in the current stabilization jar breaks down, still might cause the destruction to pipe network.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of water supply facilities in the prior art, and a kind of non-negative pressure stabilized water supply facilities of the highrise building special use that can directly link to each other with the tap water pipe network is provided.The utility model designs non-negative pressure stabilized water supply facilities, comprise frequency conversion tank, air pressure tank, pressure sensor, water pump assembly, current stabilization jar, vacuum breaker, backflow preventer, it is characterized in that: the current stabilization jar is provided with vacuum breaker, the import of current stabilization jar is connected with negative pressure preventing module, the import of negative pressure preventing module meets the water main after connecting backflow preventer again, current stabilization jar outlet links to each other with water pump assembly, on the outlet pipe of water pump assembly and be connected to air pressure tank and pressure sensor.Negative pressure preventing module is made of motor operated valve, pressure meter, controller, and pressure meter access controller, controller control line connect motor operated valve rotating drive circuit.The utility model has been set up negative pressure preventing module, current stabilization jar and vacuum breaker in the import of current stabilization jar, can directly link to each other with the tap water pipe network, the hydraulic pressure, minimizing pump head, the joint that make full use of the tap water pipe network have lacked the power consumption of investment, saved the pond, saved investment and land used, that has avoided that tap water pollutes in structure such as storage cistern may lose with spilling water.This device has disposed negative pressure preventing module, has realized dual negative pressure protection.
Description of drawings
Accompanying drawing 1 is reservoir of the prior art or cistern water supply equipment,
Accompanying drawing 2 is a non-negative pressure stabilized water supply facilities of the prior art,
Accompanying drawing 3 is a structural representation of the present utility model,
The specific embodiment
Comprise frequency conversion tank 1, air pressure tank 2, pressure sensor 3, water pump assembly 4, current stabilization jar 7, vacuum breaker 8, backflow preventer 6 among the figure, it is characterized in that: current stabilization jar 7 is provided with vacuum breaker 8, the import of current stabilization jar 7 is connected with negative pressure preventing module 9, the import of negative pressure preventing module 9 meets water main 10 after connecting backflow preventer 6 again, current stabilization jar 7 outlet links to each other with water pump assembly 4, on the outlet pipe 11 of water pump assembly 4 and be connected to air pressure tank 2 and pressure sensor 3.Negative pressure preventing module 9 is made of motor operated valve 12, pressure meter 13, controller 14, pressure meter 13 access controllers 14, and controller 14 control lines connect motor operated valve 12 rotating drive circuits 5.
In use, when its operation logic is, the water main 10 of pipe network supplies water and has entered into negative pressure preventing module 9 by backflow preventer 6, if supplying water, the water main of pipe network 10 can satisfy the water requirement, pressure meter 13 reaches setting pressure, and controller 14 is opened motor operated valve 12 by motor operated valve 12 rotating drive circuits 5, makes water main's 10 water of pipe network directly enter into supply equipment, utilize the hydraulic pressure in the pipe network, reduced the lift of supply equipment.When water use peak, the water main 10 of pipe network supplies water and can't satisfy the pressure requirement, and pressure meter 13 does not reach setting pressure, and controller 14 cuts out motor operated valve 12 by motor operated valve 12 rotating drive circuits 5.Return to and set the above upper limit that arrives of threshold pression when following when pressure meter pressure occurring in closing, motor operated valve 12 keeps the aperture state, when water main's 10 pressure of pipe network returned to capping pressure, motor operated valve 12 just passed through motor operated valve 12 rotating drive circuits 5 with its standard-sized sheet by controller 14 again.
