Description

Box relay stack water supply facilities

Technical field

The utility model relates to second pressure water supply equipment, especially a kind of box relay stack water supply facilities.

Background technology

In second pressure water supply equipment, generally there are four kinds: the no-negative-pressure water supply equipment that 1, directly utilizes the city planting ductwork overbottom pressure at present by the way of supplying water branch; 2, establish the water supply facilities (comprising band air pressure tank type) that supplies water by the booster pump pressurization in water tank or pond; 3, box pressurized pump station; 4, water tank and no negative pressure are share type.Wherein 1, way of supplying water is single in 2 two kind of water supply modes, non-negative pressure water-supply installation just shuts down when city planting ductwork is cut off the water, defectiveness aspect the water supply continuity; Supply water by the booster pump pressurization and do not use the pressure more than needed of city planting ductwork again in independent water tank or the pond of establishing, energy-conservation and the environmental protection aspect is not good enough; The 3rd kind water tank type supply equipment mostly is that supply equipment is arranged in the water tank, it is that no negative pressure equipment is arranged at the water tank outside that the 4th kind of water tank share type with no negative pressure, but these two kinds of water supply facilitiess all can not be considered the available pressure more than needed of city planting ductwork at no negative pressure equipment booster pump on type selecting, want high 10-20m in the selection of pump head.

Summary of the invention

The purpose of this utility model just provides good, the compact conformation of a kind of water supply continuity, invests and move into low box relay stack water supply facilities.

Box relay stack water supply facilities of the present utility model, comprise municipal administration water inlet main valve, non-negative pressure stabilized adjuster water inlet pipe, tank inlet pipe, non-negative pressure stabilized adjuster, header, booster pump and water outlet main valve, municipal administration water inlet main valve is leaded up to non-negative pressure stabilized adjuster water inlet pipe and is connect non-negative pressure stabilized adjuster, water tank is inserted by tank inlet pipe in another road, non-negative pressure stabilized adjuster is installed in the water tank, the delivery port and the header of non-negative pressure stabilized adjuster join, the other end of header passes through booster pump, outlet pipe is connected with the water outlet main valve, between water tank and non-negative pressure stabilized adjuster, also be provided with a water supply loop, a termination of water-supply-pipe is gone into non-negative pressure stabilized adjuster in the water supply loop, other end water receiving case is equipped with motor operated valve and relay pump on the water-supply-pipe.

Box relay stack water supply facilities operating principle of the present utility model is: municipal water supply one route water inlet main valve and tank inlet pipe enter water tank, close into water automatically when water is full, finish the water tank moisturizing; Another road enters non-negative pressure stabilized adjuster through non-negative pressure stabilized adjuster water inlet pipe, and the negative pressure cancellation element is regulated non-negative pressure stabilized adjuster internal and external pressure balance, allows water be full of non-negative pressure stabilized adjuster so that normal the conveying.When municipal flow satisfied no negative pressure system job requirement, municipal water directly passed through the frequency conversion or the power frequency work of booster water pump by non-negative pressure stabilized adjuster through header, is supplied water to the user by the water outlet main valve.By setting the required pressure of supply water of user, water supply volume increase as the user, when the hydraulic pressure of city planting ductwork is lower than the required water supply pressure of user, automatically start booster pump, regulate the hydraulic pressure in the pipe network, be increased to the required pressure of supply water of user up to ductwork pressure, guarantee that pipe network is in stable constant pressure water supply state, fully-automatic constant pressure non-negative pressure method of water supply always.When the water of peak, the pipe network water supply quantity not sufficient, when municipal administration water inlet in-pipe flow sky or non-negative pressure stabilized adjuster internal gas pressure are lower than atmospheric pressure, drawdown in the non-negative pressure stabilized adjuster, negative pressure cancellation element and electromagnetic valve are devoted oneself to work, make to keep atmospheric pressure in the non-negative pressure stabilized adjuster, be unlikely to city planting ductwork is produced negative pressure, said process is finished at short notice.When detecting city planting ductwork water inlet pipe lack of water, when pressure is reduced to a certain degree, system starts relay pump automatically and starts immediately, this moment, motor operated valve was opened automatically, relay pump is started working, deposit water in the water tank enters non-negative pressure stabilized adjuster by the relay pump pressurization through water-supply-pipe, to guarantee the continuous operation of no negative pressure system.When the satisfied no negative pressure system of municipal pipe pressure was worked, relay pump was out of service automatically.Cut off the water and relay pump when breaking down when city planting ductwork, no negative pressure system still can utilize the deposit water in the water tank to supply water, and has only when in the water tank during lack of water, and equipment just can quit work because of lacking the water source.

Box relay stack water supply facilities of the present utility model has the following advantages:

1, guarantees the continuity of water supply, remedied the defective of common non-negative pressure water-supply installation aspect the water supply continuity;

2, establish the more energy-conserving and environment-protective of water supply facilities (comprising band air pressure tank type) of water tank or pond supplying water than common by the booster pump pressurization;

3, the equipment booster pump adopts the principle how many differences mends what in the selection of lift, takes into full account the pressure that utilizes city planting ductwork, saves operation and cost of investment;

4, equipment body partly is arranged in the water tank, and compact conformation is elegant in appearance;

5, easy for installation, only need the butt joint intake-outlet just can come into operation.
