[0002] When there are multiple pressure pipes transporting the same water quality upstream, in order to consider the pressure balance of each pipeline, a new regulating storage tank is usually built at the end of each pressure pipe system.

[0028] refer to Figures 1 to 2 A multi-tube-in-one pressure manifold system according to an embodiment of the present invention is described.

[0029] like Figures 1 to 2 As shown, the multi-pipe-in-one pressure collection pipe system includes multiple water inlet pipes 100, which are used to transport water of the same quality; a collection pipe 200, where the input end of the collection pipe 200 is respectively connected to the output ends of the multiple water inlet pipes 100, and the sum of the pipe diameter cross-sectional areas of all the water inlet pipes 100 is smaller than the pipe diameter cross-sectional area of ​​the collection pipe 200, and the collection pipe 200 is used to reduce water flow turbulence; a water outlet pipe 300, where the input end of the water outlet pipe 300 is connected to the output end of the collection pipe 200, and the output end of the water outlet pipe 300 is connected to the downstream pipe network system, and the diameter of the water outlet pipe 300 is smaller than the diameter of the collection pipe 200.

[0030] like Figure 1As shown, in this embodiment, three water inlet pipes 100 are provided, all transporting water of the same quality. The left end of the water inlet pipe 100 is the input end, and the right end of the water inlet pipe 100 is the output end. The output end of each water inlet pipe 100 is connected to the input end of the manifold 200, and each water inlet pipe 100 is connected to the manifold 200 through a separate channel. The right end of the manifold 200 is the output end, and the output end of the manifold 200 is connected to the input end of the outlet pipe 300. The cross-sectional area of ​​the diameter of all water inlet pipes 100 is smaller than that of the manifold 200, and the diameter of the outlet pipe 300 is also smaller than that of the manifold 200. Therefore, by converging multiple water inlet pipes 100 into a manifold 200 at the upstream starting point or mid-end, pressure fluctuations after converging can be effectively reduced, reducing energy loss in the pressure system, thereby saving project investment and lowering subsequent operation, maintenance and management costs.

[0031] In some specific embodiments of the present invention, the water inlet pipe 100 is a pressure pipe, and the water inlet pipe 100 is made of stainless steel or plastic.

[0032] In some specific embodiments of the present invention, the water outlet pipe 300 is a pressure pipe, and the water outlet pipe 300 is made of stainless steel or plastic.

[0033] In some specific embodiments of the present invention, the collecting pipe 200 includes: a water inlet end 210, the number of the water inlet ends 210 corresponds to the number of the water inlet pipes 100, and each water inlet end 210 is connected to a corresponding water inlet pipe 100; a balancing end 220, the input end of the balancing end 220 is respectively connected to the output ends of multiple water inlet ends 210; a water outlet end 230, the input end of the water outlet end 230 is connected to the output end of the balancing end 220, and the pipe diameter of the water outlet end 230 gradually decreases in the direction away from the balancing end 220.

[0034] In some specific embodiments of the present invention, the water outlet end 230 is an eccentric reducer, and the top of the water outlet end 230 is flush with the top of the balancing end 220 .

[0035] like Figure 1As shown, the water inlet 210, the balancing end 220, and the water outlet 230 are arranged sequentially from left to right. The number of water inlet ends 210 corresponds to the number of water inlet pipes 100, that is, each water inlet pipe 100 can be independently connected to the balancing end 220 through its corresponding water inlet end 210. The input end of the water outlet 230 is connected to the output end of the balancing end 220, and the diameter of the water outlet 230 gradually decreases from left to right. It should be noted that the water outlet 230 is an eccentric reducer, and the top of the water outlet 230 is always flush with the top of the balancing end 220. The water outlet 230 reduces in diameter, that is, the bottom of the water outlet 230 gradually rises from left to right. Therefore, by reducing the diameter, the flow rate of the water in the manifold 200 can be increased. The eccentric reducer can also allow air carried by the water inlet pipe 100 to be smoothly discharged along with the water, preventing air from accumulating in the manifold 200 and affecting the stable operation of the pressure system.

[0036] In some specific embodiments of the present invention, a first valve 110 is provided at the output end of the water inlet pipe 100 , and the water inlet pipe 100 is connected to the corresponding collecting pipe 200 through the first valve 110 .

[0037] In some specific embodiments of the present invention, the output end of the collecting pipe 200 is equipped with a second valve 310 , and the collecting pipe 200 is connected to the water outlet pipe 300 through the second valve 310 .

[0038] like Figure 1 As shown, a first valve 110 is provided between each water inlet pipe 100 and the water inlet end 210, and a second valve 310 is provided between the water outlet end 230 in the collecting pipe 200 and the water outlet pipe 300, so that the collecting system can be managed, regulated and maintained according to needs to ensure that the collecting system can operate normally.

[0039] In some specific embodiments of the present invention, the diameters of the multiple water inlet pipes 100 are different from each other.

[0040] like Figure 2 As shown, in this specific embodiment, the diameters of the three water inlet pipes 100 are different from each other. Specifically, the diameters of the three water inlet pipes 100 gradually decrease from top to bottom.

[0041] In some specific embodiments of the present invention, a mud discharge pipe 400 is further included. The mud discharge pipe 400 is connected to the collecting pipe 200 and is located at the bottom of the collecting pipe 200. The mud discharge pipe 400 is equipped with a mud discharge valve 410, and the mud discharge pipe 400 is used to regularly drain the mud.

[0042] like Figure 2As shown, the mud discharge pipe 400 is provided on the manifold 200. Specifically, the mud discharge pipe 400 is connected to the balancing end 220 and is located at the bottom of the balancing end 220. The mud discharge pipe 400 is connected to the balancing end 220 through a mud discharge valve 410. It should be noted that considering that the water flow rate in the manifold 200 is too low and prone to siltation, the mud discharge pipe 400 is provided at the bottom and controlled by the mud discharge valve 410. This allows for regular emptying and mud discharge, facilitating maintenance of the manifold 200.

[0043] In some specific embodiments of the present invention, Figure 1 The water inlet pipes 100 are L1, L2, and L3, respectively, with corresponding pipe diameters of D1, D2, and D3, and corresponding pipe cross-sectional areas of A1, A2, and A3, respectively. The diameters of the water inlet end 210 of the manifold 200 correspond to the individual water inlet pipes 100, namely D1, D2, and D3, respectively. The diameter of the balancing end 220 of the manifold 200 is D4, and its corresponding cross-sectional area is A4. The first valve 110 between the water inlet end 210 of the manifold 200 and the water inlet pipe 100 is connected via a flange, and the water inlet end 210 and the balancing end 220 are welded.

[0044] The water outlet end 230 of the collecting pipe 200 is an eccentric reducer. The input end of the water outlet end 230 is welded to the output end of the balancing end 220, and its pipe diameter is D4. The output end of the water outlet end 230 is welded to the input end of the water outlet pipe 300. The pipe diameters of the output end of the water outlet end 230 and the water outlet pipe 300 are both D5, and the corresponding cross-sectional area is A5. Specifically, the output end of the water outlet end 230 is equipped with a second valve 310, and the second valve 310 is connected to the water outlet pipe 300 with a flange.

[0045] It should be noted that the relationship between the flow rate and flow velocity of the water inlet pipe 100 is as follows: And under normal circumstances, v1≈v2≈v3.

[0046] It should be noted that the flow rate Q4 at the balancing end 220 of the collecting pipe 200 is equal to Q1+Q2+Q3, wherein the relationship between the flow rate and the flow velocity is as follows: Since A4>>A1+A2+A3, then v4<v1, v4<v2, v4<v3. It can be concluded that the process of water flowing from the water inlet pipe 100 to the collecting pipe 200 is a process in which the water flow velocity is greatly reduced, that is, the kinetic energy is reduced and the potential energy is increased. The kinetic energy is converted into potential energy, which effectively reduces water flow turbulence and reduces energy loss.

[0047] It should be noted that the flow rate of the water outlet pipe 300 is Q5 = Q4 = Q1 + Q2 + Q3, wherein the relationship between the flow rate and the flow velocity is as follows: Since A5≈A1+A2+A3, v5≈v1≈v2≈v3>v4, it can be concluded that the process of water flowing from the collecting pipe 200 to the outlet pipe 300 is a process of increasing water flow velocity, that is, a process of increasing kinetic energy and decreasing potential energy. The potential energy is converted into kinetic energy, and the outlet pipe 300 returns to the normal pressure water transmission pipeline state.

[0048] Among them, the water outlet end 230 is an eccentric reducer, the top of which is flush with the balancing end 220, and the bottom is reduced in diameter. Therefore, Q4=V4·A4=Q5=V5·A5. By reducing the diameter, the flow rate V4 of the collecting pipe 200 can be increased to V5. In addition, by using an eccentric reducer, the air carried by the water inlet pipe 100 can be smoothly discharged into the water outlet pipe 300 along with the water body in the collecting pipe 200, thereby avoiding the accumulation of air in the collecting pipe 200 and affecting the stable operation of the pressure system.

[0049] It can be seen that after the multiple pressure pipes are converted by the collecting pipe 200 system, they are input by multiple water inlet pipes 100 and output by a single water outlet pipe 300, which not only reduces the number of pressure pipes, but also saves project investment and reduces pipe maintenance costs.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
