Description
Technical field
The utility model relates to water supply pressurized equipment field, especially a kind of stabilizing compensation formula non-negative pressure water-supply installation.
Background technology
At present, quickening along with urbanization process, city area constantly increases, the laying area of city tap-water company city planting ductwork is also increasing, the distance of water place and water factory of Running-water Company is more and more far away, certainly will cause the whole pressure of supply water of water supply network more and more lower, in city, the place of pressure of supply water deficiency is also just more and more, and what many places had increased storage-type secondary water-supply structure or employing immediately is that the mode supplying water without negative pressure pressurization supplies water;
Storage-type secondary water-supply is to build pond or water tank at underground or roof, and tap water is all put into pond or water tank, due to pond or the storing water in water tank time long, water flow is poor, there is structural defect in pond sealing simultaneously, so the very easily immersions such as microorganism, mosquito cause water pollution.The water coming from tap water pipe network is put into pond, the whole vanishing of original hydraulic pressure, so will build pump house, the pressurization again of starting from scratch is supplied water, waste energy.Repair pond and build pump house and take up room greatly, and cannot supply water to user while having a power failure.
The mode supplying water without negative pressure pressurization is to be mainly connected water tank with running water pipe, water tank is communicated with service pipe by control piper, the duty of control piper is controlled by electrical control cubicles, its operating principle is before tap water forced feed user, first tap water is stored in water tank, like this, when water low-valley interval, tap water pressure is met consumers' demand, by tap water self pressure, to user, supply water, when water use peak is during the period, tap water pressure can not be met consumers' demand, now electrical control cubicles will be supplied with user after the retaining pressurization in water tank by control piper, thereby realize the water demand meet user's when section in office, the application of tradition non-negative pressure water-supply installation is very extensive, but the weak point of traditional water supply equipment is: due to the restriction of water supply chamber and water tank volume, retaining in water tank can only meet the water demand of the water use peak phase user in the short time, after retaining in water tank is finished, just stop supplying water, when retaining reach a certain amount of after just again start supply water, bother very much, can not meet the round-the-clock user's request of user.
Utility model content
The shortcoming of two kinds of way of supplying water based on common in above reality; technical problem to be solved in the utility model is to provide a kind of without building pond, water tank and pump house; can prevent that water quality is contaminated; and the compensation non-negative pressure water-supply installation of a kind of Intellight voltage-stabilizing with water-shortage protection device simple in structure, reasonable in design, easy to use.
Stabilizing compensation formula non-negative pressure water-supply installation of the present utility model, comprise stabilizing compensation tank, constant voltage systems stabilisation and electrical control cabinet, described stabilizing compensation tank upper left quarter has a water inlet, water inlet and city planting ductwork feed pipe connect and compose inlet pipeline, vacuum table, valve, strainer, backflow preventer are housed on inlet pipeline successively, on stabilizing compensation tank top, pressure sensor and negative pressure inhibition device are also housed, in stabilizing compensation tank bottom, have delivery port, blowoff valve and a liquid level sensor;
Constant voltage systems stabilisation comprises pressure sensor, diaphragm-type air-compressed tank, two variable frequency pumps and a straight-through water pipe, can according to setting pressure and user's water situation successively or stack start operation, and can automatically regulate running frequency, two pumps of variable frequency pump group are standby each other; When grid power blackout causes equipment downtime or city planting ductwork hydraulic pressure to reach setting pressure of supply water, close pump group or control system dormancy, by straight-through water pipe, to user, supply water, diaphragm-type air-compressed tank be connected on user's feed pipe on, can voltage stabilizing and protection variable frequency pump group frequent starting, user's supply channel has also connected a flow meter and a pressure sensor;
Negative pressure inhibition device shown in Figure 2, comprises shell, has several outer wall pores on shell, and there are cursory ball and inner air vent in negative pressure inhibition device inside, and negative pressure inhibition device is connected with stabilizing compensation tank by connecting bolt; When device power-up is used, the water of city planting ductwork enters stabilizing compensation tank, and the air in tank is discharged from negative pressure inhibition device outer wall pore, when air is drained, cursory ball is floated by water, closes exhaust opening, stops exhaust, prevent water outlet, when current are normally carried in steady-flow tank, if any a small amount of air accumulation, arrive certain degree in tank, in tank, water level declines, cursory ball declines thereupon, and now air has steam vent to discharge; In equipment normal course of operation, when city planting ductwork output is not enough, when in inlet pipeline, water lacks, or hydraulic pressure is during lower than atmospheric pressure in steady-flow tank, in steady-flow tank, water level declines, and cursory ball declines thereupon, open pore, air amount, makes to keep atmospheric pressure in steady-flow tank, unlikely to city planting ductwork generation negative pressure.
When liquid level sensor is used at city planting ductwork shortage of water supply or stops supplying water, in tank, water level declines gradually, when water level drops to lowest water level, is, liquid level sensor signals to control system, and supply equipment is shut down.
Electrical control cabinet is in order to the data of each link of collecting device and setting and control the operation of whole equipment, can be by important parameter and the running status of electrical control color touch screen facilities for observation cashier's office in a shop.
