Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of water supply equipment, in particular to a pressurized water hammer device. BACKGROUND
[0002] In the prior art, water hammer devices are commonly used to lift fluids, particularly water, to a certain height. However, these devices have inherent limitations in pumping height, which limits their efficiency in high-altitude or high-lift applications. Traditional water hammer devices rely on a single unit of pump to lift fluids, and their pumping capacity is constrained by the pump design and power system.
[0003] To overcome these limitations, pressurization technology is introduced to improve the efficiency of water hammer devices. One common method is to increase the number of pump bodies by connecting multiple devices in series to increase the total flow gain. However, this approach results in increased equipment complexity, not only occupying more space, but also significantly increasing initial installation and operating costs.
[0004] Another strategy is to improve the internal design of the pressurizer to achieve the effect of secondary pressurization, which may include using more efficient auxiliary designs, optimizing flow channels, or adopting multi-stage compression mechanisms. Such improvements, while theoretically improving pumping performance, often require more complex manufacturing processes and even energy consumption requirements, which correspondingly increase operating costs and failure rates. SUMMARY
[0005] To this end, the present application provides a pressurized water hammer device to solve the problem of limited water hammer pumping flow in the prior art and the increased cost caused by the pressurization method.

[0023] The application will be further described in detail below with reference to the accompanying drawings.

The terms "first", "second", "third" and the like in the present application are intended to distinguish the objects referred to, and do not have a special meaning in the technical connotation aspect (for example, it should not be understood as emphasizing the importance or order, etc.). The expressions such as "including", "containing", "having" and the like also mean "not limited to" (some units, components, materials, steps, etc.).
[0025] The terms such as "upper", "lower", "left", "right", "intermediate" and the like referred to in the present application are generally made for the purpose of indicating the relative position relationship for intuitive understanding with reference to the drawings, and are not an absolute limitation on the position relationship in the actual product.
[0026] A pressurized water hammer device, with reference to Figure 1 , comprising a water inlet pipe 1, a water outlet pipe 2 and a pressure storage bin 3, the pressure storage bin 3 is higher than the water inlet pipe 1 and the water inlet is communicated with the water inlet pipe 1, and the water outlet is communicated with the water outlet pipe 2. The internal water of the pressure storage bin 3 increases the air pressure, and the bottom is provided with a first one-way valve 8, which is used to allow the water flow of the water inlet pipe 1 to flow to the pressure storage bin 3, and to prevent the water in the pressure storage bin 3 from flowing to the water inlet pipe 1.
[0027] It should be noted that in the embodiment of the present application, the connection position of the pressure storage bin 3 and the water outlet pipe 2 is above the one-way valve 8, so that after the water flow enters the pressure storage bin 3 and is pressurized, it will only flow smoothly to the water outlet pipe 2 and will not flow into the water inlet pipe 1.
[0028] The pressurized water hammer device further comprises a self-pressurizing pipeline 4. The self-pressurizing pipeline 4 is communicated with the water outlet end of the water inlet pipe 1, and the other end of the self-pressurizing pipeline 4 is bent upward to form a pressurizing section 5, and a pressurizing drain valve 11 is installed at the end of the pressurizing section 5.
[0029] A plurality of water inlet pipes 6 are connected to the pressurizing section 5, and the ends of all the water inlet pipes 6 away from the pressurizing section 5 are communicated with the water outlet pipe 2. Specifically, in order to ensure the pumping effect, 3-6 water inlet pipes 6 are provided, and in the embodiment of the present application, 4 water inlet pipes 6 are provided. The connection positions of the four water inlet pipes 6 and the pressurizing section 5 are at different heights and are distributed along the axial direction.
[0030] Correspondingly, the water source position (i.e. the water inlet end of the water inlet pipe 1) is 6-8 meters higher than the pressurized water hammer device (i.e. the water outlet end of the water inlet pipe 1); the water inlet position (i.e. the water outlet end of the water outlet pipe 2) is 18-24 meters higher than the pressurized water hammer device (i.e. the water inlet end of the water outlet pipe 2).
[0031] Further, a second one-way valve 9 is arranged at a position close to the pressurizing section 5 of each upper water pipe 6, and is used to allow water in the pressurizing section 5 to flow into the upper water pipe 6, and to prevent water in the upper water pipe 6 from flowing into the pressurizing section 5. Through this arrangement, when the water flow at the pressurizing section 5 increases, the water pressure will also increase, thereby opening the second one-way valve 9, and then the high-pressure water will flow into the upper water pipe 6, and then flow into the water outlet pipe 2 along the upper water pipe 6.
[0032] The other two ports of the four three-way interfaces 7 are connected to the water outlet pipe 2 in a series connection manner.
[0033] The implementation principle of the embodiment is that water at the water source flows into the device along the water inlet pipe 1, and a relatively balanced water pressure state is formed in the device.
[0034] When the starting water drain valve 10 is opened, the water in the water pipe 1 will overflow due to the pressure difference (6-8 meters), and then the flow rate will increase, so that the water pressure in the device increases, and when the pressure reaches a certain value, the starting water drain valve 10 will be automatically closed. At this time, the water pressure in the device increases dramatically, and the first one-way valve 8 is opened due to the pressure difference, and part of the water flows into the pressure storage bin 3 to increase the pressure.
[0035] The water after being pressurized flows into the water outlet pipe 2 from the bottom of the pressure storage bin 3, and the second one-way valve 9 is opened, so that the high-pressure water flows into the upper water pipe 6, and finally flows into the water outlet pipe 2, thereby forming a higher water flow, which is pumped out of the device (18-24 meters).
[0036] With the water flowing into the pressure storage bin 3 and the water outlet pipe 2, the water pressure in the two increases, and gradually becomes greater than the water pressure in the water inlet pipe 1, the self-pressurizing pipeline 4 and the pressurizing section 5. At this time, the first one-way valve 8 and the second one-way valve 9 will be automatically closed to prevent water from flowing back. After the first one-way valve 8 and the second one-way valve 9 are closed, the water pressure will generate a reaction force to push the water in the water inlet pipe 1, the self-pressurizing pipeline 4 and the pressurizing section 5 to flow back, thereby reducing the water pressure in the water inlet pipe 1, the self-pressurizing pipeline 4 and the pressurizing section 5. At this time, the starting water drain valve 10 and the pressurizing water drain valve 11 will be automatically opened, and the next working process will be started, thereby forming an automatic circulation working process.
[0037] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradictions). In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described. The embodiments not explicitly described should also be considered as the scope of the present disclosure.
