Background technology
Current secondary water-supply equipment: the non-negative pressure water-supply installation that a class is common, needs to install vacuum suppresser, user side air pressure tank etc., complex structure, control, connect complexity, cost is high, and use vacuum suppresser easily to bring the impurity in air into drinking water, not environmentally.Another kind of is that cavity-separating residual quantity compensates non-negative pressure water-supply installation, vacuum tank adopts a point chamber welding procedure, although solve some problems of traditional non-negative pressure water-supply installation, but manufacture craft is quite complicated, high pressure chest weld seam is easy to crack, affect application life, cost increases, and reduces the water space of steady-flow tank.
In view of the above defect of traditional non-negative pressure water-supply installation, my department have developed novel residual quantity and compensates non-negative pressure water-supply installation.
Utility model content
The utility model solves the problem such as inadequate environmental protection, Structure and energy complexity of the existence of traditional non-negative pressure water-supply installation, also reduces cost simultaneously.
The invention provides a kind of novel non-negative pressure water-supply installation.The utility model relates to residual quantity and compensates non-negative pressure water-supply installation.Its critical piece comprises: stabilizing compensation tank, main pump, switch board, the gasholder water-fast gas of the equivalent pressure of water under high pressure (after the pre-stored pump), constant voltage chamber, flap valve, ball valve, three-way magnetic valve, motor operated valve, Counterflow-proof device, pressure transmitter, water inlet conflux house steward, filter clamor, water outlet collecting pipe, municipal inlet tube.
Residual quantity of the present invention compensates non-negative pressure water-supply installation, and its current order and modular construction are closed and be: municipal water, after mechanical filter, enters Counterflow-proof device, by motor operated valve, enters constant voltage chamber.The import of outlet pipe one road, constant voltage chamber water pump, a route three-way magnetic valve is connected with stabilizing compensation tank, and the other end and the water outlet of three-way magnetic valve house steward of confluxing is connected.Conflux house steward and water outlet is confluxed between house steward and is installed booster pump.Municipal inlet tube and user's outlet pipe are provided with pressure transmitter.
When municipal pressure is normal, municipal administration water passes through backflow preventer, the arrival end of water pump is arrived by the current stabilization in constant voltage chamber, supercharging through water pump assembly is supplied water to user, simultaneously, water pump rear portion water under high pressure through three-way magnetic valve from A mouth through B mouth to the moisturizing of stabilizing compensation tank, water is full of compensating tank and just gas is pushed back in gasholder, complete the first water impoundment to stabilizing compensation tank, now water under high pressure after the pressure P 1 of gas and water pump in the pressure of water, gasholder in stabilizing compensation tank, three kinds of pressure are equal.
The water use peak phase, when municipal water supply can not meet the use water of user, motor operated valve is by the feedback of pressure transmitter, automatic adjustment degree of opening, ensure not produce negative pressure minimum pressure P2 to city planting ductwork, maximize and supply water to user, three-way magnetic valve conversion simultaneously, cut off the B-A direction that stabilizing compensation tank is connected with user's water main, and open stabilizing compensation tank with to B-C direction, constant voltage chamber, to the moisturizing of constant voltage chamber, the air release pressure in gasholder compensates out the water under high pressure in voltage stabilizing compensating tank, after converging with municipal water, supply water to user through water pump assembly supercharging.Realize the function of stabilizing compensation.
When in stabilizing compensation tank, water enters constant voltage chamber, municipal water demand is diminished, municipal ductwork pressure rises, control system opens large valve to motor operated valve signal, city planting ductwork supplies water normal, and electric T-shaped valve is changed, now after water pump water under high pressure to the retaining of stabilizing compensation tank, until vacuum tank water is full, gas is just pushed back in gasholder, now complete stabilizing compensation tank retaining and moisturizing process again.
During low discharge voltage stabilizing packing state, water pump assembly and control system are in resting state, and rely on gasholder, three-way magnetic valve is often opened with service pipe B-A and is connected, and plays voltage stabilizing pressure maintaining effect to user pipe.
Three-way magnetic valve also can adopt multiple electrically operated valve to replace, and realizes its switching function.
Three-way magnetic valve can also adopt hydraulic diaphragm three way cock to replace.
The volume V2 type selecting of stabilizing compensation tank 1 calculates according to law of conservation of energy P1V1=P2 (V1+V2), ensure that the economic serviceability of complete equipment.
The utility model has the advantages that: simpler than traditional non-negative pressure water-supply installation structure, manufacture craft process is simple, achieves residual quantity and compensates, and install simple, small investment, system water supply is stablized, and fully ensure that system end pressure.Integration Specialty Design, compact conformation, good looking appearance, this equipment configuration energy-saving frequency conversion pump, utilize superposition pressure and the automatic frequency-conversion method of operation of pipe network, energy-saving effect is significantly improved.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model and embodiment are described further.
Detailed description of the invention, when municipal pressure is normal, municipal administration water is by backflow preventer 10, the arrival end of water pump 2 is arrived by the current stabilization in constant voltage chamber 5, supercharging through water pump assembly is supplied water to user, meanwhile, after water pump a road water through three-way magnetic valve 8 to stabilizing compensation tank 1 moisturizing, as shown in figure tri-(1), three-way magnetic valve water (flow) direction A → B.
The water use peak phase, municipal water supply can not meet the use water of user, and motor operated valve 9, by the feedback of pressure transmitter 11, automatically regulates motor operated valve open degree, ensures not produce negative pressure to city planting ductwork, maximize and supply water to user.Three-way magnetic valve 8 is changed simultaneously, and the water of voltage stabilizing compensating tank 1 is compensated out, as shown in figure tri-(2), and three-way magnetic valve water (flow) direction B → C.After converging with municipal water, supply water to user through water pump assembly 2 supercharging.
During low discharge voltage stabilizing packing state, water pump assembly 2 and control system are in resting state, and rely on gasholder 4, three-way magnetic valve 8 and user pipe are often opened and be connected, as shown in figure tri-(3), and the water (flow) direction B → A of three-way magnetic valve.Voltage stabilizing pressure maintaining effect is played to user pipe.
