[0023] In the following, the application will be further described in conjunction with specific embodiments, and it should be noted that, without conflict, the following described embodiments or technical features can be combined to form new embodiments.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0026] The terms "include" and "have" in the specification and claims of the present application, as well as any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] One of the preferred embodiments of the present application, as shown in Figures 1 to 5 A centralized gas supply system for the inflation of energy storage devices of die casting machines, comprising an energy storage tank 1 and an energy storage assembly 2 arranged outside the factory building, and an inflation pipe line architecture 3 arranged inside the factory building; the energy storage tank 1 is adapted to compress and deliver the gas in the tank to the energy storage assembly 2 by a compressor; the inflation pipe line architecture 3 is uniformly distributed in multiple die casting machine assembly areas inside the factory building, and the gas inlet end of the inflation pipe line architecture 3 is connected to the energy storage assembly 2, so that the energy storage assembly 2 supplies gas to multiple die casting machine assembly areas through the inflation pipe line architecture 3.

[0028] It should be known that in the prior art, the air supply system of the die casting machine energy storage tank inflation cannot quickly and effectively supply air to the die casting machine assembly area in the factory building, and cannot effectively detect the air supply amount of the plurality of energy storage tanks 20. Such conditions are prone to cause the energy storage tank 20 to be repeatedly inflated with gas in the tank body and prone to cause the air supply of the total pipeline 30 under unstable conditions, which is prone to cause safety hazards.

[0029] As can be understood from the above, the energy storage assembly 2 can store the gas compressed and delivered by the compressor in the energy storage tank 1. Therefore, as shown in the figure, the energy storage assembly 2 includes a plurality of energy storage tanks 20. The energy storage tank 1 delivers the gas in the tank to the plurality of energy storage tanks 20 by the compressor; the gas outlet ends of the plurality of energy storage tanks 20 are connected with the inflation pipeline architecture 3; by simultaneously controlling the opening and closing of the gas outlet end valves of the plurality of energy storage tanks 20, the air supply of the energy storage assembly 2 to the inflation pipeline architecture 3 is controlled, so that the inflation pipeline architecture 3 can simultaneously supply air to the die casting machine assembly area in the factory building under the condition that the gas outlet end valves of the plurality of energy storage tanks 20 are opened. Figure 2

[0030] It should also be known that from the above, the inflation pipeline architecture 3 is connected with the energy storage assembly 2 to collectively supply air to the die casting machine assembly area in the factory building. However, if the air inlet ends of the inflation pipeline architecture 3 are respectively connected with the energy storage assembly 2, and then collectively supply air to the die casting machine assembly area in the factory building; such pipeline design is too complex, which is not conducive to the arrangement of the pipeline, and also not conducive to the stable delivery of the gas. Therefore, the inflation pipeline architecture 3 is provided with the total pipeline 30 and the plurality of branch pipelines 31 in the embodiment, and the plurality of branch pipelines 31 are arranged in the die casting machine assembly area in the factory building and connected with the total pipeline 30. At the same time, the total pipeline 30 is connected with the plurality of energy storage tanks 20 in the energy storage assembly 2, which is equivalent to that the energy storage assembly 2 supplies air to the total pipeline 30 in the inflation pipeline architecture 3, and then collectively supplies air to the die casting machine assembly area in the factory building through the plurality of branch pipelines 31.

[0031] As can be understood, after a long time of use, the energy storage tank 20 may be damaged or the gas in the tank body may be delivered, thereby causing the gas pressure of the total pipeline 30 to be unstable, and further causing the pressure of the plurality of branch pipelines 31 to be unstable. However, unstable gas delivery is prone to cause safety hazards, so the plurality of energy storage tanks 20 need to be able to stably supply air to the inflation pipeline architecture 3 in the embodiment.

[0032] Therefore, in the embodiment, as shown in the figure, Figure 3 ​As shown, the energy storage assembly 2 further comprises regulating valves 21 and detection devices. Meanwhile, the regulating valves 21 and the detection devices are also provided in plurality. The regulating valves 21 and the detection devices are correspondingly installed at the outlet ends of the energy storage tanks 20; the detection devices can detect the working pressure or the working flow of the energy storage tanks 20, and the regulating valves 21 can adjust the opening degree according to the detection results of the detection devices. Meanwhile, the energy storage assembly 2 further comprises a plurality of conveying pipes 22, both ends of the conveying pipes 22 are connected with the opening ends of the energy storage tanks 20 and the main pipeline 30 respectively.

[0033] In the embodiment, in the case that the energy storage tanks 20 supply the main pipeline 30 with unstable gas, there are multiple methods for the regulating valves 21 and the detection devices to cooperate and adjust. The specific methods and adjustment modes will be specifically explained by the following two examples.

[0034] Example 1: As shown, Figure 4 When the detection device detects that the working pressure or the working flow of at least one energy storage tank 20 is lower than the set first threshold value, the regulating valve 21 corresponding to the energy storage tank 20 with the working pressure or the working flow lower than the set first threshold value is closed, and after the above-mentioned regulating valve 21 is closed, the opening degree of the regulating valve 21 corresponding to the remaining energy storage tank 20 with normal working pressure or working flow is adjusted and increased.

[0035] Specifically, when the detection device detects that the working pressure or the working flow of at least one energy storage tank 20 is lower than the set first threshold value, the detection device sends a first control signal for closing to the regulating valve 21 corresponding to the energy storage tank 20, and sends a second control signal for increasing the opening degree to the remaining energy storage tanks 20.

[0036] In the example, the first threshold value can be set as the minimum gas supply amount of the gas in the energy storage tank 20 under the condition that the energy storage tank 20 can normally deliver, and the first threshold value can be set according to the actual needs of the person skilled in the art, for example, the first threshold value can be set as 5% to 10% of the rated pressure or the rated flow of the energy storage tank 20. In order to facilitate understanding, the following will be explained in detail by a specific example.

[0037] As shown, Figure 4As shown, it is assumed that the energy storage assembly 2 contains a total of 16 energy storage tanks 20, and the theoretical gas supply amount of each energy storage tank 20 is a, so the total pipeline 30 has a gas supply amount of 16a. When the detection device detects that the working pressure or working flow of two energy storage tanks 20 is lower than the first threshold value, it means that the two energy storage tanks 20 cannot normally deliver gas to the total pipeline 30. Therefore, the two regulating valves 21 corresponding to the two energy storage tanks 20 that cannot normally supply gas can be closed. At this time, the actual gas supply amount of the total pipeline 30 is 14a. However, the stable gas supply amount required by the total pipeline 30 is 16a, so the opening degree of the 14 regulating valves 21 corresponding to the remaining 14 energy storage tanks 20 that can normally supply gas needs to be increased, so that the gas supply amount of the remaining 14 energy storage tanks 20 that can normally supply gas increases from a to a+(1 / 7)a. In this way, the gas supply amount of the total pipeline 30 can be restored to 16a again, thereby maintaining the stable inflation of the multiple die casting machine assembly areas in the factory building.

[0038] It should be understood that the total number of energy storage tanks 20, the number of tank bodies whose working pressure or working flow is lower than the set first threshold value, and the gas supply amount of the energy storage tank 20 are only exemplary, and can be set by the person skilled in the art according to actual needs.

[0039] Example II: As shown in Figure 5 When the detection device detects that the difference between the working pressure or working flow of at least one pair of energy storage tanks 20 exceeds the set second threshold value, the opening degree of the regulating valve 21 corresponding to the energy storage tank 20 with larger working pressure or working flow is increased, and the opening degree of the regulating valve 21 corresponding to the energy storage tank 20 with smaller working pressure or working flow is decreased.

[0040] Specifically, when the detection device detects that the difference between the working pressure or working flow of at least one pair of energy storage tanks 20 exceeds the set second threshold value, it sends a third control signal for increasing the opening degree to the regulating valve 21 corresponding to the energy storage tank 20 with larger working pressure or working flow, and sends a fourth control signal for decreasing the opening degree to the regulating valve 21 corresponding to the energy storage tank 20 with smaller working pressure or working flow.

[0041] In this example, the specific value of the second threshold value can be selected by the person skilled in the art according to actual needs, for example, the difference between the working pressure or output flow of a pair of energy storage tanks 20 can be set to 4% to 9% of the rated pressure or rated flow. For the convenience of understanding, one specific example will be described in detail below.

[0042] As shown in Figure 5As shown, it is assumed that the total number of energy storage tanks 20 in the energy storage assembly 2 is 16, and the theoretical average flow rate of each energy storage tank 20 is a; in the actual detection, it is found that the actual flow rate of one of the energy storage tanks 20 is 105%, and the actual flow rate of another energy storage tank 20 is 95%, at this time, the actual flow rate difference between the two energy storage tanks 20 is 10%a, which is greater than the set second threshold value, so it is necessary to reduce the opening of the regulating valve 21 corresponding to the energy storage tank 20 with the maximum actual flow rate, and at the same time, increase the opening of the regulating valve 21 corresponding to the energy storage tank 20 with the minimum actual flow rate, so that the working flow rates in all energy storage tanks 20 tend to be average.

[0043] It should be understood that the total number of energy storage tanks 20 and the gas supply amount of the energy storage tank 20 described above are only exemplary, and can be set by the actual needs of those skilled in the art.

[0044] In this embodiment, the detection device includes a sensor and a controller. The sensor can be a pressure sensor 23 or a flow sensor according to different detection parameters. In this embodiment, the pressure of the gas in the energy storage tank 20 is detected by the pressure sensor 23. The controller is used to receive the detection results of the sensor and send corresponding control signals.

[0045] Taking example one described above, the pressure sensor 23 is correspondingly installed at the outlet of the 16 energy storage tanks 20; when the working pressure or working flow rate of a pair of energy storage tanks 20 detected by the pressure sensor 23 is lower than the set first threshold value, the controller will send a first control signal to close the regulating valve 21 corresponding to the above-mentioned pair of energy storage tanks 20 according to the detection result of the pressure sensor 23, so that the corresponding pair of energy storage tanks 20 stops supplying gas; at the same time, the controller will also send a second control signal to increase the opening of the regulating valve 21 corresponding to the remaining 14 energy storage tanks 20 with normal working pressure or working flow rate, so that the gas supply amount of the 14 energy storage tanks 20 increases.

[0046] Taking example two described above, the pressure sensor 23 is correspondingly installed at the outlet of the 16 energy storage tanks 20; when the actual flow rate difference of a pair of energy storage tanks 20 detected by the pressure sensor 23 is greater than the set second threshold value, the controller will send a third control signal to increase the opening of the regulating valve 21 corresponding to the energy storage tank 20 with the larger working pressure or working flow rate according to the detection result of the pressure sensor 23, so that the flow rate of the corresponding energy storage tank 20 increases; at the same time, the controller will also send a fourth control signal to reduce the opening of the regulating valve 21 corresponding to another energy storage tank 20 with the smaller working pressure or working flow rate, so that the flow rate of the corresponding energy storage tank 20 decreases.

[0047] It should be understood that the specific structure and working principle of the pressure sensor 23 and the controller are known to those skilled in the art, and thus will not be described in detail here. Generally, the controller can be installed in the factory building to control all the regulating valves 21, or a central controller can be used to control all the regulating valves 21 in the entire central gas supply system.

[0048] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
