Description
Technical field
The utility model relates to a kind of storage device of non-negative pressure water-supply installation, belongs to a kind of non-negative pressure method of water supply water storage apparatus.
Background technology
Steady flow compensator is the essential core parts of non-negative pressure water-supply installation, its operating principle is: no-negative-pressure water supply equipment comes into operation, and the water of tap water pipe network enters the steady-flow tank of steady flow compensator, and in tank, air is discharged from vacuum breaker, after water is full of, vacuum breaker is closed automatically.When tap water pipe network pressure can meet require with water time, system is directly supplied water to grid by bypass check valve; When tap water pipe network pressure can not meet require with water time, system pressure signal feeds back to frequency-variable controller by distance-transmission pressure gauge, water pump operation, and according to the fast constant pressure water supply of the size self-regulating rotary of water supply volume, if when running water pump reaches power frequency rotating speed, then start the running of another pump variable frequency.Common steady flow compensator does not possess the function that high pressure stores, and therefore there is the storage water yield few, corresponding supply equipment volume is large, and the defects such as resource consumption is large, can not meet user demand.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, and provide a kind of moisture storage capacity large, volume is little, can save material, reduces the storage device of the non-negative pressure water-supply installation of use cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of storage device of non-negative pressure water-supply installation, comprise the steady flow compensator that has high pressure chest and low pressure chamber, described steady flow compensator is provided with a water inlet be connected with tap water pipe network by inlet channel, be communicated with by tube connector between described high pressure chest and low pressure chamber, the tube connector being communicated with described high pressure chest and low pressure chamber is provided with pressure switching valve, check device and pump successively.
The related content of technique scheme is explained as follows:
In technique scheme, described check device is flap valve.
Further technical scheme, described pump is connected with the outlet conduit be connected with grid with user.
Due to the employing of technique scheme, the utility model compared with prior art tool has the following advantages:
Because the utility model is provided with high pressure chest, low pressure chamber, force (forcing) pump and pressure switching valve, steady flow compensator of the present utility model is made to have storage of higher pressures function, store more than the twice of the water yield higher than common steady flow compensator, the steady flow compensator volume-diminished half of identical capacity, better can save material, make non-negative pressure water-supply installation volume less simultaneously, be conducive to saving floor space, reduce use cost.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one structural representation.
In above accompanying drawing: 1, steady flow compensator; 2, water inlet; 3, high pressure chest; 4, low pressure chamber; 5, pressure switching valve; 6, tube connector; 7, check device; 8, pump; 9, outlet conduit.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, the storage device of a kind of non-negative pressure water-supply installation of the utility model, comprise the steady flow compensator 1 that has high pressure chest 3 and low pressure chamber 4, steady flow compensator 1 is provided with a water inlet 2 be connected with tap water pipe network by inlet channel, be communicated with by tube connector 6 between described high pressure chest 3 and low pressure chamber 4, the tube connector being communicated with described high pressure chest 3 and low pressure chamber 4 is provided with pressure switching valve 5, check device 7 and pump 8 successively, pump 8 is connected with the outlet conduit 9 be connected with grid with user.
Operating principle of the present utility model is: tap water flow in steady flow compensator 1 by water inlet 2, when water flow pressure is greater than 0MPa, tap water is through check device (flap valve) 7, pressurizeed by pump 8, pressure switching valve 5 is opened, water enters high pressure chest 3, when pressure is close to 0MPa, pressure switching valve 5 is closed, and the water of high pressure chest 3 enters low pressure chamber 4.
The storage device of non-negative pressure water-supply installation of the present utility model, structure is simple, reliable operation, water storage efficiency are high.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
