With reference to Figures 2 to 6, Figure 2 representatively shows a perspective view of another angle of the water supply equipment; Figure 3 representatively shows a top view of the water supply equipment; Figure 4 representatively shows The bottom view of the water supply equipment; a partial view of the water supply equipment is representatively shown in FIG. 5, specifically showing the main structure of the surge tank 100; another partial view of the water supply equipment is representatively shown in FIG. 6, Specifically, the connection relationship between the surge tank 100 and the expansion tank 500 is shown. Below in conjunction with above-mentioned accompanying drawing, the utility model is described in detail.

As shown in Figures 1 to 4, in this embodiment, the surge tank 100 has a horizontal arrangement, and the surge tank 100 has two opposite ends, and the water inlet 111 of the surge tank 100 is arranged near the above-mentioned On the top of one of the two ends, the water outlet 112 is disposed near the bottom of the other of the two ends. Specifically, the surge tank 100 mainly includes a frame body 120 and a tank body 110 erected on the frame body 120 . Wherein, the tank body 110 is provided with a water inlet 111 and a water outlet 112, and both the water inlet 111 and the water outlet 112 are preferably arranged in a vertical direction. In addition, the water outlet 112 is connected with a water outlet pipe 1121 through a flange, and the water outlet pipe 1121 extends downward and bends horizontally toward the water inlet main pipe 300, and the water inlet main pipe 300 is connected to a water inlet pipe corresponding to the position of the water outlet pipe 1121. 310, the water inlet pipe 310 extends horizontally toward the water outlet pipe 1121, and the water inlet pipe 310 and the water outlet pipe 1121 are connected together through the flanges at both ends, so that the water in the surge tank 100 flows into the water inlet main pipe 300. Combining the flow field distribution in the surge tank 100 shown in Figure 13, it can be seen that based on the horizontal design of the surge tank 100 and the design of the water inlet 111 and the water outlet 112, the flow through the water inlet 111 and the water outlet 112 The flow state of the water flow through the surge tank 100 is improved. As shown in Figure 13, the flow field at each end corner of the surge tank 100 is relatively uniform and dense, avoiding the flow field distribution of the surge tank in the existing equipment Uneven and prone to the problem of dead water areas, to achieve the effect of removing dead water areas and preventing the accumulation of chloride ions, it can better improve the anti-corrosion performance, and is more conducive to the realization of the self-cleaning function.

Specifically, in this embodiment, the surge tank 100 can be made of SS304 stainless steel, the surface of which is polished, and the pressure is maintained at 1.0 MPa for the sealing test. In addition, a liquid level sensor may be provided in the surge tank 100 to monitor the information of the liquid level in the tank. At the top of the tank body 110 of the surge tank 100, such as the water inlet 111, a vacuum suppressor 113 (as shown in Figure 8) can also be configured to provide a related pressure display function, so that under extreme conditions, air intake can prevent the pipe network from Negative pressure occurs. In other embodiments, based on the design of the horizontal arrangement of the surge tank 100, the arrangement and relative positions of the water inlet 111 and the water outlet 112 of the surge tank 100 can also be selected in other forms, and are not limited to this embodiment. .

Based on the above, when the water consumption peaks, if the flow rate of the water pump 200 is greater than the flow rate of the tap water pipe network, the water in the surge tank 100 can still maintain a normal water supply for a certain period of time as a supplementary water source. At this time, the air enters the tank body 110 through the vacuum suppressor. In the air cavity of the tank body, the vacuum formation in the tank body 110 is destroyed, so that the pipe network for whom the tap water is supplied does not generate negative pressure.

As shown in FIG. 5 , in this embodiment, a plurality of baffles 121 are arranged around the outer periphery of the frame body 120 , so that the frame body 120 has a box-like or other closed shape. The expansion tank 500 connected with the surge tank 100 is located below the tank body 110 of the surge tank 100 , is surrounded by a frame body 120 , and is closed by a baffle 121 . Based on the above design of the frame body 120 structure, the frame body 120 can lift the tank body 110 on the basis of supporting the tank body 110, and the expansion tank 500 is arranged below the tank body 110. For this, it will It will be described in detail later in the contents of the expansion tank 500 , and will not be repeated here. Moreover, due to the surrounding and sealing of the baffle plate 121, the equipment, pipelines and valves such as the expansion tank 500 and the water outlet 112 under the tank body 110 are further protected, and at the same time, the integrity of the appearance of the surge tank 100 is improved. more beautiful. In addition, a number of openings 1211 and inspection ports are provided on the baffle plate 121 for passage of pipelines and inspection by operators.

As shown in Figure 6, in this embodiment, the number of expansion tanks 500 is designed to be two and connected to the surge tank 100 respectively. 121 surrounds it. Specifically, the expansion tank 500 is provided with a gas storage area and a water storage area, and a flexible diaphragm is provided between the gas storage area and the water storage area. The water storage area is connected to the tank body 110 of the surge tank 100 through pipelines, and the gas storage area is filled with pressurized gas. Among them, in this embodiment, the pressure gas may preferably be nitrogen (N ₂ ), or an inert gas, that is, a rare gas, such as helium (He), neon (Ne), argon (Ar), krypton (Kr) , Xenon (Xe) and Radon (Rn), can be flexibly selected according to the performance requirements and cost budget of the pressure gas. The inner wall of the expansion tank 500 located in the water storage area is coated with an anti-rust and anti-corrosion coating to improve the anti-rust and anti-corrosion performance of the expansion tank 500, and the material of the flexible diaphragm can be preferably EPDM environmental protection rubber, FKM fluororubber or stainless steel sheet and other flexible materials with anti-rust properties.

Based on the above, in the water supply equipment proposed by the utility model, the gas storage area and the water storage area of the expansion tank 500 are separated by a flexible diaphragm. The pressure in the gas storage area pushes the flexible diaphragm to squeeze the water storage area, and the water in the water storage area is squeezed into the surge tank 100 to stabilize the water outlet pressure of the equipment. Specifically, since the diaphragm type expansion tank is a sealed container, when a large flow of water is supplied, it is pressurized by the water pump 200, and the pressure gas stored in the gas storage area of the expansion tank 500 is compressed. The compressed pressure gas releases pressure and expands, and transports the water stored in the water storage area of the expansion tank 500 to the water supply pipe network to supplement the user's small flow water or pipe network leakage, and at the same time make the main pump (that is, the water pump used as a common water pump) It is in shutdown state when the water flow is small or zero.

It is easy to understand that, in order to arrange the expansion tank 500 connected with the surge tank 100, various modifications, additions, substitutions, deletions or other changes are made to the quantity, installation location and specific material selection of the above-mentioned expansion tank 500, these Variations remain within the scope of the principles of the invention. For example, in other embodiments, the number of expansion tanks 500 may be one or more than two. When there are multiple expansion tanks 500 , their connection positions relative to the surge tank 100 are not limited to the bottom of the tank body 110 , and the positions of the expansion tanks 500 are not limited to be the same. In addition, the selection of the above-mentioned pressure gas and the setting of the anti-rust and anti-corrosion coating can also be flexibly adjusted according to actual needs.

Further, in this embodiment, the air pressure in the gas storage area of each expansion tank 500 is greater than 60% of the air pressure in the surge tank 100 , and is more preferably 60%-80% of the air pressure in the surge tank 100 . Because when the water pressure from the water supply pipe network in the surge tank 100 is unstable, the internal pressure of the surge tank 100 will be unstable. Based on the above design, the gas storage area in the expansion tank 500 can release or absorb a certain pressure, which can Further compensating for underpressure situations.

As shown in FIGS. 1 to 4 , in this embodiment, the number of water pumps 200 is designed to be three, and may preferably be vertical water pumps. Specifically, the three water pumps 200 can be divided into the first water pump, the second water pump and the third water pump according to the work priority, and they are respectively connected in parallel between the surge tank 100 and the water outlet pipeline to work independently. In addition, each water pump 200 has a pump inlet pipe 220 and a pump outlet pipe 230, and the pump inlet pipe 220 and the pump outlet pipe 230 of each water pump 200 are connected to the water inlet main pipe 300 and the water outlet main pipe 400 respectively. Wherein, taking the water supply of buildings in the utility model as an example, the first water pump is a commonly used water pump to meet the water supply demand of low head. The second water pump is an auxiliary water pump, which can also be understood as a common water pump to meet the water supply demand of high head. The third water pump is a standby water pump, which can meet the emergency water supply demand when at least one of the other water pumps 200 fails. In other embodiments, the number of water pumps 200 can be flexibly adjusted according to the characteristics of the pipe network where the utility model is located, and at least two water pumps 200 are designed to meet the needs of normal water supply and emergency backup water supply respectively. In addition, when the number of water pumps 200 is more than three, based on the above description of the functions of each water pump 200 , the water pump 200 realizing the same function is not limited to one, and the function realized by each water pump 200 is not limited to one kind. Based on the design concept above, the multi-stage water pump group composed of the water pumps of the present invention can preferably adopt a two-stage water pump group or a three-stage water pump group. For example, Grundfos integrates multi-stage vertical centrifugal frequency conversion water pumps, and cooperates with check valves, maintenance valves, inlet and outlet pipelines, outlet-side pressure gauges, outlet-side pressure sensors and steel bottom plate foundations to form the multi-stage water pump group , is not limited to this. Wherein, FIG. 12 representatively shows a schematic perspective view of the three-dimensional structure of the check valve 210 . Specifically, the check valve 210 adopts a multi-channel structure, which mainly includes a valve seat 211 and three valve cores 212 installed on the valve seat 211, and the valve cores 212 are preferably spring-type valve cores, so that the check valve The valve 210 can still function normally at low flow rates, allowing fluid to pass through relatively easy openings. If a single large spool is used, the spring load is generally relatively large, and the pressure loss is large when the fluid passes through. However, multiple small spools 212 have relatively small loads to ensure that the check valve 210 is under low fluid pressure. work normally.

Furthermore, in this embodiment, the water supply equipment proposed by the present utility model may also include a frequency conversion controller to control the working status of each water pump 200 respectively.

Wherein, the main water outlet pipe 400 is respectively connected to two water outlet components, and the two water outlet components are respectively connected to the water outlets of the two water pumps 200 . Moreover, the water outlet 112 of the surge tank 100 is connected to the water inlet pipeline through a pipeline. Based on the above design, when the water pump 200 works and the relevant valve group is opened, the incoming water flowing into the municipal tap water pipe network of the surge tank 100 through the water inlet 111 of the surge tank 100 flows out from the water outlet 112 of the surge tank 100 and passes through the pipeline. The water flows into the water inlet main pipe 300, and then is pumped into the water outlet main pipe 400 by the water pump 200, and finally flows into, for example, the tap water pipeline of building users.
