Abstract
本实用新型公开了一种无负压供水装置，包括与市政供水管网连接的储水罐，储水罐通过输水管道串联有加压水泵组，加压水泵组连接有出水管，所述的储水罐内设置有稳压罐，稳压罐内充有高压气体，稳压罐通过稳压管道与出水管连通。本实用新型将稳压罐设置在储水箱的内部，一方面节省了安装空间，另一方面，由于稳压罐同时受到其内部的气压和外部储水箱内部的水压，因此，稳压罐的罐壁能够设置的薄一点，有效节约了生产成本；另外，将输水管道位于储水罐内部的一端设置为向下弯曲的结构，能够防止水中的异物进入到管道内部，起到了自动净水的供能，提高了供水质量。
The utility model discloses a non-negative pressure water supply device, which comprises a water storage tank connected to a municipal water supply pipe network. The water storage tank is connected in series with a pressurized water pump group through a water delivery pipeline, and the pressurized water pump group is connected with a water outlet pipe. A pressure-stabilizing tank is arranged in the water storage tank, and the pressure-stabilizing tank is filled with high-pressure gas, and the pressure-stabilizing tank is communicated with the outlet pipe through the pressure-stabilizing pipeline. In the utility model, the surge tank is arranged inside the water storage tank, which saves installation space on the one hand, and on the other hand, since the surge tank is simultaneously subjected to the internal air pressure and the water pressure inside the external water storage tank, the pressure of the surge tank The tank wall can be set a little thinner, which effectively saves production costs; in addition, the end of the water delivery pipeline inside the water storage tank is set as a downward bending structure, which can prevent foreign matter in the water from entering the inside of the pipeline and play an important role in automatic water purification. energy supply and improve the quality of water supply.
Description
Technical field
The utility model belongs to the supply equipment technical field, relates in particular to a kind of non-negative pressure method of water supply device.
Background technology
Progress along with sociometric technique; Municipal water supply system water quality standard progressively improves; Water supply capacity constantly strengthens; For adapting to the social development requirement; Non-negative pressure water-supply installation has appearred in the supply equipment field; The direct city planting ductwork of this non-negative pressure water-supply installation is the water source; Form airtight relay pressurizing way of supplying water continuously; Avoided the water quality standard that the traditional secondary supercharging water supply system causes to reduce a various pollution of waterhead problem; This non-negative pressure water-supply installation is mainly by water storage tank; Water pump assembly; Vacuum tank and intelligence control system form; Acting as of described voltage-stabiliser tube; Water supply is played on the one hand the effect of buffering when city planting ductwork comes the water yield less than user's water supply volume; On the other hand various sudden changes are impacted and had cushioning effect; Can prevent the frequent start-stop of water pump assembly.
There are some deficiencies in existing non-negative pressure water-supply installation: 1, described vacuum tank normally is exposed in air, and owing to being filled with gases at high pressure in vacuum tank, therefore, it is thicker that the tank skin of vacuum tank arranges, and in addition, the occupation of land space is larger; 2, there is no water purification function, make quality of water supply not guarantee.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of non-negative pressure method of water supply device, can realize automatic water purifying and assure feed water safety.
In order to realize the foregoing invention purpose, the utility model adopts technical scheme as described below:
A kind of non-negative pressure method of water supply device, comprise the water tank that is connected with municipal network water supply, water tank is in series with the pressure pump group by aqueduct, the pressure pump group is connected with outlet pipe, be provided with vacuum tank in described water tank, be filled with gases at high pressure in vacuum tank, vacuum tank is communicated with outlet pipe by the voltage stabilizing pipeline.
Further, an end of described aqueduct is positioned at water tank inside, and the end is bent downwardly.
Further, the bottom of described water tank is provided with sewage draining exit, and the sewage draining exit place is connected with blow-off line, is provided with blowoff valve on described blow-off line.
Owing to adopting technique scheme, the utlity model has following superiority:
1, described vacuum tank is arranged on the inside of storage tank, has saved installing space on the one hand, on the other hand, be subject to simultaneously the hydraulic pressure of its inner air pressure and outside storage tank inside due to vacuum tank, therefore, it is thinner that the tank skin of vacuum tank can arrange, and effectively saved cost of production;
2, the aqueduct end that is positioned at water tank inside is set to reclinate structure, can prevent that the foreign matter in sealing enters into pipe interior, has played the energy supply of automatic water purifying, has improved quality of water supply.
Description of drawings
Fig. 1 is structure principle chart of the present utility model;
In figure: the 1-water tank; The 2-vacuum tank; 3-voltage stabilizing pipeline; The 4-outlet pipe; 5-pressure pump group; The 6-blow-off line; The 7-blowoff valve; The 8-aqueduct.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of non-negative pressure method of water supply device, comprise the water tank 1 that is connected with municipal network water supply, water tank 1 is in series with pressure pump group 5 by aqueduct 8, pressure pump group 5 is connected with outlet pipe 4, be provided with vacuum tank 2 in described water tank 1, be filled with gases at high pressure in vacuum tank 2, vacuum tank 2 is communicated with outlet pipe 4 by voltage stabilizing pipeline 3.
One end of described aqueduct 8 is positioned at water tank 1 inside, and the end is bent downwardly, and can prevent in storage tank that the foreign matter in water enters into aqueduct inside, has played the automatic water purifying energy supply.
The bottom of described water tank 1 is provided with sewage draining exit, and the sewage draining exit place is connected with blow-off line 6, is provided with blowoff valve 7 on described blow-off line.
One end port of described aqueduct 8 is conducive to higher than the sewage draining exit of water tank bottom setting the discharge that storage tank deposits to the dirt of its bottom.
Operating principle of the present utility model is: storage tank of the present utility model is connected with municipal network water supply, described outlet pipe is connected with the user, and the utility model is equipped with and compares frequency-variable controller, when the municipal tap water output is large, part hydraulic pressure enters in vacuum tank by the voltage stabilizing pipeline and compresses its inner gas, and automatically regulate pressure pump unit by frequency-variable controller this moment; During less than user's water supply volume, air pressure and hydraulic pressure in vacuum tank provide power, have guaranteed that the municipal tap water pipe network negative pressure can not occur when the municipal tap water output, and what utilize is the former pressure of tap water, can not affect other users, have guaranteed water supply security.
