Description
技术领域technical field
本实用新型涉及一种供水系统。The utility model relates to a water supply system.
背景技术Background technique
传统的供水方式离不开蓄水池，蓄水池中的水一般自来水管供给，这样有压力的水进入水池后压力降为零，大量的能源便白白地浪费了。随着二次供水加压技术的发展，无负压供水设备从根本上解决了这些问题。无负压供水设备不需建造水塔，投资小、占地少，采用水气自动调节、自动运转、节能与自来水自动并网，停电后仍可供水，调试后数年不需看管。比建造水塔节约投资70％，比建造高位水箱节约投资60％，大大节约土建投资。The traditional water supply method is inseparable from the cistern. The water in the cistern is generally supplied by tap water pipes. After the pressured water enters the pool, the pressure drops to zero, and a large amount of energy is wasted in vain. With the development of secondary water supply pressurization technology, non-negative pressure water supply equipment fundamentally solves these problems. The non-negative pressure water supply equipment does not need to build a water tower. It has small investment and occupies less land. It adopts automatic adjustment of water and gas, automatic operation, energy saving and automatic grid connection of tap water. Compared with building a water tower, it saves 70% of investment, and saves 60% of investment compared with building a high-level water tank, which greatly saves civil construction investment.
目前的无负压供水设备只保证其出水口的供水压力，而不重视公共管网供水压力的作用，当公共管网供水压力不足时，会影响供水系统自身及管网中其他供水系统的正常运行。此外，用于为储水箱提供压力的气体储压罐中的水不能自动循环，这部分死水会对供水系统造成污染。The current non-negative pressure water supply equipment only guarantees the water supply pressure of its water outlet, and does not pay attention to the water supply pressure of the public pipe network. When the water supply pressure of the public pipe network is insufficient, it will affect the normal operation of the water supply system itself and other water supply systems in the pipe network. run. In addition, the water in the gas pressure storage tank used to provide pressure for the water storage tank cannot be automatically circulated, and this part of stagnant water will pollute the water supply system.

上述供水系统的运作方式为：将公共供水管网7内的水引入，经过内部的调控，再通过出水管42导出供用户使用。其中，内部的调控方法具体为：The operation mode of the above-mentioned water supply system is as follows: the water in the public water supply pipe network 7 is introduced, and after internal control, it is exported through the water outlet pipe 42 for users to use. Among them, the internal control methods are as follows:
控制主机1将控制阀21打开，让公共供水管网7内的水流入第一储水箱22，第一储水箱22内的水再流入第一管线3，控制主机1通过调控变频器51使水泵52将第一管线3内的水引入第二管线4，第二管线4内的水再通过出水管42导出供用户使用；The control host 1 opens the control valve 21 to allow the water in the public water supply pipe network 7 to flow into the first water storage tank 22, and then the water in the first water storage tank 22 flows into the first pipeline 3, and the control host 1 controls the frequency converter 51 to make the water pump 52 introduce the water in the first pipeline 3 into the second pipeline 4, and then export the water in the second pipeline 4 through the outlet pipe 42 for use by users;
其中，第一压力传感器31用于检测第一管线3内水的输出压力值P1，并将该输出压力值P1传送给控制主机1，控制主机1将P1与内部的预设压力值进行对比，第二压力传感器41用于检测第二管线4内水的输入压力值P2，并将该输出压力值P2传送给控制主机1，控制主机1将P2与内部的预设压力值进行对比；Among them, the first pressure sensor 31 is used to detect the output pressure value P 1 of the water in the first pipeline 3, and transmit the output pressure value P 1 to the control host 1, and the control host 1 compares P 1 with the internal preset pressure value For comparison, the second pressure sensor 41 is used to detect the input pressure value P 2 of the water in the second pipeline 4, and transmit the output pressure value P 2 to the control host 1, and the control host 1 compares P 2 with the internal preset pressure value for comparison;
当P1大于内部的预设压力值时，即表示公共供水管网7内的供水压力充足，控制主机1便会通过变频器调节水泵的转速和功率，保障压力值P2在恒定要求范围内，从而保障出水管42的稳定供水；当P1小于内部的预设压力值时，即表示公共供水管网7内的供水压力不足，控制主机1便会再通过变频器5调节水泵52的转速和功率，保障压力值P1在要求范围内，从而保障第一管线3内的水压稳定。在上述过程中，第一气体储压罐23与第一储水箱22协同运转，用于保障第一储水箱22内的压力恒定，以避免公共供水管网7的供水压力不足造成不良影响，当第一储水箱22内的压力较大时，部分水注入罐内，压缩罐内的空气，当第一储水箱22内的压力较小时，罐内的水则会被排出；第二气体储压罐62亦同理，与第二储水箱61协同运转，用于保障第二储水箱61内的压力恒定，从而进一步保障出水管42处供水的稳定；其中，第一气体存储罐和第二气体存储罐内都不会存留不能循环的死水，保障了用户的用水健康；When P 1 is greater than the internal preset pressure value, it means that the water supply pressure in the public water supply pipe network 7 is sufficient, and the control host 1 will adjust the speed and power of the water pump through the frequency converter to ensure that the pressure value P 2 is within the constant required range , so as to ensure the stable water supply of the water outlet pipe 42; when P 1 is less than the internal preset pressure value, it means that the water supply pressure in the public water supply pipe network 7 is insufficient, and the control host 1 will then adjust the speed of the water pump 52 through the frequency converter 5 and power to ensure that the pressure value P1 is within the required range, thereby ensuring the stability of the water pressure in the first pipeline 3 . In the above process, the first gas pressure storage tank 23 and the first water storage tank 22 operate in cooperation to ensure that the pressure in the first water storage tank 22 is constant, so as to avoid adverse effects caused by insufficient water supply pressure of the public water supply pipe network 7. When the pressure in the first water storage tank 22 is high, part of the water is injected into the tank to compress the air in the tank. When the pressure in the first water storage tank 22 is low, the water in the tank will be discharged; The tank 62 is also the same, and works in conjunction with the second water storage tank 61 to ensure that the pressure in the second water storage tank 61 is constant, thereby further ensuring the stability of the water supply at the outlet pipe 42; wherein, the first gas storage tank and the second gas storage tank There will be no stagnant water that cannot be circulated in the storage tank, which ensures the health of the user's water;
当P2大于内部的预设压力值时，即表示出水管42处的出水量较低，控制主机1可关闭控制阀21、降低水泵52功率(甚至关闭部分水泵52)，由第一储水箱22、第二储水箱61内的水用于供给，这一过程中，第一气体储压罐23和第二气体储压罐62亦协同运转，保障出水管42处供水的稳定。When P2 is greater than the internal preset pressure value, it means that the water output at the water outlet pipe 42 is low, and the control host 1 can close the control valve 21, reduce the power of the water pump 52 (or even turn off part of the water pump 52), and the first water storage tank 22. The water in the second water storage tank 61 is used for supply. During this process, the first gas pressure storage tank 23 and the second gas pressure storage tank 62 also work together to ensure the stability of the water supply at the outlet pipe 42 .
以上所述实施例仅表达了本实用新型的具体实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。The above-mentioned embodiments only express the specific implementation manners of the utility model, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the utility model.
