Description

Technical Field

[0001] This invention relates to the field of water supply, specifically to a whole-pipeline circulating water supply system without dead water. Background Technology

[0002] Currently, high-quality water (such as piped drinking water) or chlorine-free, ozone-preserved water systems all require water circulation. However, because high-rise buildings require pumping water to the top floor and then discharging it downwards in stages (top-down supply), pressure differences between the supply and return pipes can cause stagnant water in the floor distribution branch pipes. The current practice is to create a loop between the supply pipe (upstream) and the return pipe (downstream), connecting the distribution branch pipes to each floor's user area. A pump then pumps the water through the supply pipes to the top floor, allowing users to access water through the floor distribution branch pipes connected to the supply pipes. However, this results in water circulating in the supply and return pipes, but not in the floor distribution branch pipes (the pipes used by users on those floors). This compromises water quality in the floor distribution branch pipes and seriously affects user safety. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a whole-pipeline circulating water supply system without stagnant water. This system consists of multiple water supply modules, each with pipes laid out in the same direction, and pressure-reducing series connections between modules to achieve water circulation without stagnant water in each pipeline.

[0004] The technical solution adopted in this invention is as follows: a whole-pipeline non-dead-water circulation water supply system, including a water supply pipe that delivers water to the top floor, and a water supply module connected to the water supply pipe. Several water supply modules are set according to the floor height and are interconnected. Each water supply module includes a water supply pipe, a return water pipe, and floor distribution branch pipes. The water supply pipe is connected to the water supply pipe. One end of the floor distribution branch pipe is connected to the water supply pipe, and the other end of the floor distribution branch pipe is connected to the return water pipe. A pressure reducing component and an air venting component are provided at the upper end of the water supply pipe in the water supply module.

[0005] Furthermore, the water supply modules are connected to each other via return water pipes and supply water pipes.

[0006] Furthermore, a booster pump is installed at the lower end of the water supply pipe.

[0007] Furthermore, the exhaust assembly includes an automatic exhaust valve.

[0008] Furthermore, the pressure reducing assembly includes a pressure reducing valve installed at the upper end of the water supply pipe and a pressure gauge installed at the rear end of the pressure reducing valve.

[0009] Furthermore, it also includes a flow meter for calculating water flow rate and a valve for controlling water flow rate in the pipe, both of which are installed at the lower end of the return water pipe of the lowest water supply module.

[0010] The beneficial effects of this invention are as follows: This invention is equipped with multiple water supply modules, and each water supply module is laid out in the same direction to control the water flow circulation, thereby ensuring that the water flow in the pipe will not stagnate in a certain area and affect the water quality. A pressure reducing component is set between two water supply modules, and the pressure is connected in series between the water supply modules to control the pressure in the water supply modules within the allowable range, thereby ensuring that users can use water normally. In addition, an air venting component is also set at the highest point of the water supply module (i.e., in the pipeline after the pressure reducing component) to remove free gas in each water supply module during the water supply process, thereby ensuring water circulation and maintaining water quality.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 , Figure 4 As shown, a whole-pipeline non-dead-water circulation water supply system includes a water supply pipe 1 and a water supply module connected to the water supply pipe 1. The water supply module can be set in several units according to the floor height and connected in series with each other to reduce pressure. At the same time, each water supply module corresponds to a floor in a region, and the floor distribution branch pipes 4 of different floors in the same water supply module need to be laid out in the same direction.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the water supply module includes a water supply pipe 3, a return pipe 2, and floor distribution branch pipes 4. The uppermost water supply module has its internal water supply pipe 3 connected to the water supply pipe 1. The lower water supply modules are connected to the water supply pipe 3 via the return pipe 2, meaning the return pipe 2 of one water supply module is connected to the water supply pipe 3 of the next water supply module, thus circulating the water. The inlet end of the floor distribution branch pipe 4 is connected to the water supply pipe 3, and several floor distribution branch pipes 4 are evenly arranged on the water supply pipe 3 from top to bottom. Each floor distribution branch pipe 4... For each floor, the floor water distribution branch pipes 4 of different floors in the same water supply module need to be laid out in the same direction. The return end port of the floor water distribution branch pipe 4 is connected to the return water pipe 2. The water supply pipe 3 diverts the water flow to supply each floor water distribution branch pipe 4, thereby guiding the water flow to the corresponding floor. The return water pipe 2 is used for water return, concentrating the water flow in the floor water distribution branch pipe 4 and flowing it to the next water supply module, thereby circulating the water flow and ensuring that the water flow in the pipe does not stagnate in a certain area, creating stagnant water and affecting the use.

[0019] The venting component and pressure reducing component 6 are installed at the upper end of the water supply pipe 3, so that the water flow from the previous water supply module can only flow into the next water supply module after passing through the pressure reducing component 6 and the venting component. The pressure reducing component reduces the pressure inside the pipe, thereby regulating the pressure inside the water supply module and ensuring normal water use for users.

[0020] The venting assembly includes an automatic venting valve 5, which is used to remove free gas from each water supply module during the water supply process. The pressure reducing assembly 6 is installed in the pipeline before the automatic venting valve 5. The pressure reducing assembly 6 includes a pressure reducing valve and a pressure gauge installed at the rear end of the pressure reducing valve. The pressure reducing valve is used to reduce the pressure of the liquid in the pipeline, while the pressure gauge is used to detect the pressure of the water flow in the pipeline after pressure reduction. The pressure reducing assembly 6 keeps the water flow pressure entering the next water supply module within the allowable range, thereby ensuring normal water use for users. Each water supply module is equipped with an automatic venting valve 5 and a pressure reducing assembly 6, so that the pressure can be adjusted independently and the water flow in the water supply module can be circulated, thereby ensuring the water quality for users on each floor.

[0021] A booster pump (not shown in the figure) is provided at the lower end of the water supply pipe 1 to pump water to the upper floor. In addition, a flow meter 8 for calculating the water flow rate and a valve 7 for controlling the water flow rate in the pipe are also included. The flow meter 8 and the valve 7 are both installed at the lower end of the return water pipe 2 of the lowest water supply module.

[0022] This invention includes multiple water supply modules, each with its own pipeline, to control water circulation and prevent water from stagnating in any area, thus affecting water quality. A pressure-reducing component is installed between two water supply modules, connecting them in series to control the pressure within each module and ensuring normal water usage. Furthermore, an venting component is located at the highest point of each water supply module (in the pipeline behind the pressure-reducing component) to remove free gas from each module during water supply, thereby ensuring water circulation and maintaining water quality.

[0023] The above description is only a preferred embodiment of the present invention. The present invention is not limited to the above embodiments. Minor structural modifications may occur during implementation. If various modifications or variations of the present invention do not depart from the spirit and scope of the present invention and fall within the scope of the claims and equivalent technologies of the present invention, the present invention also intends to include these modifications and variations.
