It is necessary to set up a pressurized water supply system to supply water for this water point. In previous designs, clean water tanks - automatic constant pressure variable flow water supply devices and stacked water supply devices were often used to realize pressurized water supply. At the same time, with the "Code for Design of Water Supply and Drainage in Buildings" (GB50015-20032009 Edition), the requirements for water-proof pollution have been improved, and some areas such as chemical agent tank farms, chemical workshops, laboratory buildings (medicine, pathology, biochemistry) and other areas need water supply pipes. Set the air gap; the water point in the corresponding project must be equipped with a clean water tank - automatic constant pressure variable flow device pressurized water supply. However, these water supply pressurization devices are relatively large in volume and scattered in equipment.

实施例Example
如图1所示，为带空气间隙小流量一体化供水装置外部正视图，所述的带空气间隙小流量一体化供水装置包括不锈钢柜体，如图2所示，所述的不锈钢柜体具有进水口9、出水口10和溢流排污口11，如图3所示，不锈钢柜体内设有带空气间隙的不锈钢过渡水箱2，不锈钢过渡水箱2的顶部和底部分别连接进水管和出水管，进水管和出水管分别连接进水口9和出水口10，出水管连接内置止回阀的管中泵6，不锈钢过渡水箱2还连接溢流排污管4，溢流排污管4连接溢流排污口11。不锈钢过渡水箱2的出水管还连接气压罐7，所述的出水口10设有压力表8。不锈钢过渡水箱2顶部连接防虫透气管5。As shown in Figure 1, it is an external front view of an integrated water supply device with an air gap and a small flow rate. The integrated water supply device with an air gap and a small flow rate includes a stainless steel cabinet. As shown in Figure 2, the stainless steel cabinet has The
所述带空气间隙小流量一体化供水装置进水补至不锈钢过渡水箱2，不锈钢过渡水箱2的进水口与其溢流液位(HH.L，高高液位)之间有充足的空气间隙h(150mm)，具备有效的防止给水回流污染的功能。不锈钢过渡水箱2的容积需保证有3min的装置设计流量，水以装置3min的最大流量4m3/h计算，不锈钢过渡水箱2的容积不应小于200L。不锈钢过渡水箱2供管中泵6吸水。The integrated water supply device with air gap and small flow is supplied with water to the stainless steel
如图4所示，所述的不锈钢柜体的下部设有检修门，检修门上集成有装置智能控制器1，不锈钢过渡水箱2内设有水位计，不锈钢过渡水箱2的进水管上设有进水电动阀3，装置智能控制器1连接水位计、进水电动阀3和管中泵6。所述带空气间隙小流量一体化供水装置进水通过液位信号，由装置智能控制器1，实现对不锈钢过渡水箱2的自动补水，补水方式如下：当不锈钢过渡水箱2液位达到MH.L(中高液位)，开启进水电动阀3，开始补水；当液位达到H.L(高液位)，关闭进水电动阀3，停止补水。当液位到达HH.L(高高液位)，不锈钢过度水箱2通过溢流排污管4溢流，装置报警。As shown in Figure 4, the lower part of the stainless steel cabinet is provided with an inspection door, an intelligent device controller 1 is integrated on the inspection door, a water level gauge is provided in the stainless steel
管中泵6用作加压水泵，该水泵、电机均选用不锈钢材料，泵组和电机内的轴承采用水润滑轴承，不需要添加任何润滑油，根本上解决了充油式电机带来的漏油、水质污染问题；同时由于该泵的电机和水泵部分完全密闭在管道中，水泵电机部分被循环水环绕，依靠水的流动对电机进行散热冷却，电机运行超静音，噪声可降低至约40分贝，根本上解决了电机噪音问题。水泵外观简洁美观，占地小，安装拆卸方便。The in-pipe pump 6 is used as a pressurized water pump. The water pump and the motor are made of stainless steel. The bearings in the pump unit and the motor are lubricated with water, without adding any lubricating oil, which fundamentally solves the leakage caused by the oil-filled motor. Oil and water pollution problems; at the same time, because the motor and water pump part of the pump are completely sealed in the pipeline, the motor part of the water pump is surrounded by circulating water, relying on the flow of water to dissipate heat and cool the motor, the motor runs ultra-quiet, and the noise can be reduced to about 40 decibels, which fundamentally solves the problem of motor noise.

When the device is running, set the operating pressure of the device according to the water pressure requirements of the water point, and start an in-pipe pump 6 according to the water volume requirements of the water point, and control the frequency conversion operation of the water pump through the pressure of the water outlet (air pressure tank 7 and pressure gauge 8 are set at the water outlet) , the operating parameters are flow rate Q=0.8～2m 3 /h, head H=30～60m. With the increase of water consumption, when the flow rate is greater than 2m 3 /h, the second water pump starts frequency conversion operation. The corresponding technical parameters of the device are: flow Q=0.8~4m 3 /h, head H=30~60m; power P=1.0~2.2kW.
所述带空气间隙小流量一体化供水装置通过装置智能控制器1，根据不锈钢过渡水箱2的液位控制管中泵6的启停：L.L(低液)1台水泵停止，LL.L(低低液位报警)2台水泵停止并报警。同时装置也可通过装置智能控制器1切换至手动操作，用启停按钮控制管中泵6的水泵工频运行。装置单台管中泵6工频运行参数为流量Q＝2.35m3/h，扬程H＝60m；功率P＝1.1kW。The integrated water supply device with an air gap and small flow is controlled by the intelligent controller 1 of the device, according to the start and stop of the pump 6 in the liquid level control pipe of the stainless steel transition water tank 2: LL (low liquid) 1 water pump stops, LL.L (low liquid) Low liquid level alarm) 2 water pumps stop and alarm. Simultaneously, the device can also be switched to manual operation through the device intelligent controller 1, and the power frequency operation of the water pump of the pump 6 in the pipe can be controlled with the start-stop button. The power frequency operation parameters of a single in-pipe pump 6 in the device are flow rate Q=2.35m 3 /h, head H=60m; power P=1.1kW.
