Detailed Description

The secondary water supply facility generally includes a water storage tank connected to a municipal water pipe through a water supply pipe (hereinafter, this water supply pipe is referred to as a municipal water supply pipe), a water inlet end of the water pump connected to the water storage tank, a water outlet pipe of the water pump connected to a water outlet device of a user, and an electric control device, etc., and the water pump supplies water in the water storage tank to the water outlet device (e.g., a faucet) of the user. In the related art, in order to monitor whether the water flow rate into the water storage tub is stable and to detect the amount of water municipal supplied into the water storage tub, a flowmeter is generally provided on the municipal water supply pipe to monitor whether the water flow rate in the municipal water supply pipe is stable and to detect the amount of water municipal supplied into the water storage tub. However, since the utility water supply pipeline is usually a pipeline having a slightly larger pipe diameter, water flowing through the utility water supply pipeline is not filled in a normal condition, thereby making data detected by a flowmeter provided on the utility water supply pipeline inaccurate.

Therefore, according to the embodiment of the utility model, the first reducing pipeline is connected to the municipal water supply pipeline, and the inner pipe diameter of the first reducing pipeline is smaller than that of the municipal water supply pipeline, so that the full pipe degree of water flowing through the first reducing pipeline is larger than that of water flowing through the municipal water supply pipeline, and the accuracy of detecting the water flow flowing through the municipal water supply pipeline can be increased by detecting the water flow flowing through the first reducing pipeline through the flowmeter.

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Since the utility water supply pipeline 100 is usually designed with a margin, i.e. a pipeline with a slightly larger pipe diameter is usually selected, in a normal case, water flowing through the utility water supply pipeline 100 is not full, so that data detected by a flowmeter provided on the utility water supply pipeline 100 is inaccurate, in the embodiment of the utility model, by connecting a section of the first reducing pipeline 300 to the utility water supply pipeline 100, the inner pipe diameter of the first reducing pipeline 300 is smaller than the inner pipe diameter of the utility water supply pipeline 100, so that the full pipe length of water flowing through the first reducing pipeline 300 is larger than the full pipe length of water flowing through the utility water supply pipeline 100, and by detecting the water flow through the first reducing pipeline 300 by the first flowmeter 400, the accuracy of detecting the water flow through the utility water supply pipeline 100 can be increased.

In some embodiments of the present utility model, in order that the arrangement of the first reduced diameter tube 300 does not affect the water flow, the inner diameter of the first length of tube 110 is the same as the inner diameter of the second length of tube 120, and the model of the first reduced diameter tube 300 is one step smaller (one number smaller) than the model of the first length of tube 110.

Alternatively, two backwashing devices 111 are provided, and the two backwashing devices 111 are connected in parallel to the first section of pipeline 110. The two backwashing devices 111 are arranged in parallel, so that one backwashing device 111 of the two backwashing devices 111 is a standby device, therefore, when the backwashing devices 111 need to be overhauled, water consumption of users cannot be influenced, and valves are arranged on pipelines on two sides of each backwashing device 111 and used for opening or cutting off pipeline passages.

Based on the fact that the water pressure in the municipal water supply pipe is large, in order to reduce the impact of the water pressure on the water storage tub 200, the second-stage pipe 120 is connected with the pressure reducing valve group 112. Optionally, two pressure reducing valve groups 112 are provided, and the two pressure reducing valve groups 112 are connected in parallel and arranged in the second section of pipeline 120.

That is, the second end of the second-stage pipe 120 is connected to the water diversion pipe 500, both ends of the water diversion pipe 500 are connected to the two water storage buckets 200, respectively, and the water flowing through the second-stage pipe 120 is divided into two streams within the water diversion pipe 500, one stream flowing into the first water storage bucket 200 and the other stream flowing into the second water storage bucket 200. The provision of the plurality of water storage tanks 200 enables more water to be stored, so that the water supply of the secondary water supply system is more stable.

With continued reference to fig. 1, the secondary water supply system further includes a first water supply pipe 700 and a plurality of second water supply pipes 800, each water storage tub 200 is connected with a water outlet pipe 600, each water outlet pipe 600 is connected with an ultraviolet sterilizer 610, the ultraviolet sterilizer 610 sterilizes water flowing out of the water storage tub 200 to ensure the safety of water for users, and each water outlet pipe 600 is connected with the first water supply pipe 700. One end of each of the plurality of second water supply pipes 800 is connected to the first water supply pipe 700, that is, the inside of the water storage tub 200 is supplied to the first water supply pipe 700 through the water outlet pipe 600, and the water in the first water supply pipe 700 flows into each of the second water supply pipes 800, respectively.

Similarly, the second water supply pipe 800 is designed with a margin, i.e. a pipe with a slightly larger pipe diameter is usually selected, so that in normal circumstances, the water flowing through the second water supply pipe 800 is not full, so that the data detected by the flowmeter provided on the second water supply pipe 800 is inaccurate, therefore, a section of second reducing pipe 820 is connected to the second water supply pipe 800, the inner pipe diameter of the second reducing pipe 820 is smaller than the inner pipe diameter of the second water supply pipe 800, so that the full pipe diameter of the water flowing through the second reducing pipe 820 is larger than the full pipe diameter of the water flowing through the second water supply pipe 800, and the accuracy of detecting the water flow through the second reducing pipe 820 can be increased by detecting the water flow through the second flowmeter 821.
