Description

A kind of secondary water-supply steady flow compensation system
Technical field
The utility model belongs to supply equipment technical field, is specifically related to a kind of secondary water-supply steady flow compensation system.
Background technology
Can negative interaction be produced after general supply equipment directly accesses tap water pipe network at present, because the flow of water pump is usually greater than running water pipe flow of inlet water, thus cause ductwork pressure to decline, affect periphery user water.In order to solve the irrationality of this water supply scheme, so traditional way of supplying water needs to build water source water tank and attic tank in the import department of water pump, there are three problems in this traditional water supply scheme, first, all easily there is pollution problem in water pump water source water tank and attic tank, because the design in pond all exists overfall, the water tank of life also must periodic cleaning for avoiding water quality to degenerate, and thus causes the waste of drinking water.The second, the building cost of attic tank is higher, and along with the development in city, attic tank is also difficult to see.3rd, the tap water in city planting ductwork first will be put into water source water tank and then be extracted into attic tank with water pump, and like this, the pressure energy of tap water has just been wasted.
People have developed the secondary water supply system with steady flow compensation function for this reason, in secondary water supply system design process, when the water yield of city planting ductwork, hydraulic pressure can not meet the water yield, the hydraulic demand of user's pipe network, all needing, secondary pressurized equipment is set a water is promoted thus meets the needs of user's water.
At present, second pressure water supply equipment main on market is non-negative pressure water-supply installation, can match, but in actual application, above equipment still exists more problem and shortage, makes user's pipe network job insecurity according to the concrete supply and demand condition of project.
Utility model content
The purpose of this utility model is solve above-mentioned technical problem and provide a kind of secondary water-supply steady flow compensation system without negative pressure.
For achieving the above object, the utility model adopts following technical scheme:
A kind of secondary water-supply steady flow compensation system, comprises steady flow compensation tank, is provided with vacuum suppresser and fluid level controller in described steady flow compensation tank; A pressure chamber and a steady flow compensation chamber is formed by the first pressure-bearing dividing plate in described steady flow compensation tank; Described vacuum suppresser is arranged on described first dividing plate; Described steady flow compensation chamber is included one and to be filled with the high pressure chest of gases at high pressure in advance by the common pressure chamber and formed by the second pressure-bearing dividing plate that anti-negative pressure flow-limiting valve is connected with city planting ductwork water inlet pipe, nontoxic rubber capsule is provided with in described high pressure chest, the intake-outlet of described nontoxic rubber capsule connects two-way compensating device, described two-way compensating device also connects the suction side of described common pressure chamber water side and variable frequency pump, and described two-way compensating device is also connected to the supply channel for supplying water to user.
The water inlet pipe that described steady flow compensation tank connects with city planting ductwork is provided with at least one backflow-proof valve.
Described water inlet pipe is provided with y-type filter, and this y-type filter is located at the influent side of described backflow-proof valve.
Vacuum suppresser is arranged on the inside of steady flow compensation tank by the utility model, when tap water enters into common pressure chamber, vacuum suppresser is opened and is entered in pressure chamber by the eliminating atmosphere of common pressure chamber inside, pressure chamber is totally-enclosed, not with contacting external air, thus stopped the pollution of air to tap water, and there is bidirectional compensating function, stable water supply further, and it is frequent to solve water pump start and stop, voltage stabilizing function is not enough, the problem that discharge pressure changes greatly, and water system is run safer stable, energy-efficient.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of secondary water-supply steady flow compensation system that the utility model embodiment provides.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
