Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas circuit control equipment technology, specifically to a gas circuit intelligent automatic distribution device. Background Technology
[0002] In industrial production, scientific research and other fields, it is often necessary to distribute the gas output from the gas source to different gas-using equipment according to a certain proportion or demand. The gas distribution device is the key equipment to achieve this function.
[0003] Utility model patent CN214427380U discloses a multi-channel standard gas distribution device, comprising: N standard gas branches, each standard gas branch connected to a standard gas source, where N is a positive integer greater than 2; the N standard gas branches connected to a mixing tube; and the mixing tube connected to an analyzer. The advantages of this multi-channel standard gas distribution device are: it allows simultaneous access to multiple alternative standard gases, enabling rapid selection and replacement between these gases without frequent cylinder movement, and avoids gas mixing.
[0004] Although the above technical solutions have corresponding advantages, existing gas distribution devices still have some shortcomings in use. For example, traditional gas distribution devices mostly use manual valves for control, requiring operators to manually adjust the opening of each valve to achieve gas distribution. This is not only cumbersome to operate, but also has low distribution accuracy, making it difficult to meet the requirements of scenarios with high gas flow control. At the same time, manual operation is prone to errors due to human factors, affecting the accuracy of production or experiments.
[0005] On the other hand, some gas distribution devices lack real-time monitoring capabilities, failing to obtain parameters such as gas pressure and flow rate from each branch in a timely manner. When abnormalities occur in the gas path (such as excessive pressure or unstable flow rate), they cannot issue alarms or take corresponding protective measures in a timely manner, which may damage gas-using equipment or even cause safety accidents. In view of this, we propose an intelligent automatic gas distribution device. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figures 1-3 This utility model provides a technical solution: an intelligent automatic gas distribution device, including a device housing 1, a main pipe 10 fixedly installed inside the device housing 1, and an air inlet connector 11 fixedly installed at the air inlet end of the main pipe 10, which extends out of the device housing 1 for easy connection to a gas source; a total pressure sensor 12 and a total flow sensor 13 are fixedly installed on the main pipe 10, which can monitor the gas pressure and flow rate in the main pipe in real time, providing data support for controlling the gas state in the main pipe.
[0034] like Figure 1 and Figure 2 As shown, multiple branch pipes 3 are detachably installed on the main pipeline 10, extending out of the device housing 1. Electromagnetic proportional valves 30 are fixedly installed on the branch pipes 3, and branch flow sensors 31 and branch pressure sensors 32 are also fixedly installed on the branch pipes 3. A controller 15 is fixedly installed inside the device housing 1, and a display 17 is fixedly installed outside the device housing 1. The electromagnetic proportional valves 30 can accurately adjust the gas flow rate, and the branch flow sensors 31 and branch pressure sensors 32 can monitor the gas parameters of each branch pipe in real time. The controller 15 inside the device housing 1 receives and processes these parameters, while the external display 17 displays the parameters intuitively, realizing precise control and status monitoring of the gas in each branch.
[0035] In this embodiment, the end of the main pipe 10 away from the air inlet connector 11 is not connected to the outside. The number of branch pipes 3 is 5 to 8, which ensures that the gas in the main pipe can flow smoothly to each branch pipe 3 to meet the needs of multiple gas uses.
[0036] like Figure 1 As shown, a horizontally arranged support cylinder 14 is fixedly installed on the inner wall of the device housing 1. The end of the main pipe 10 away from the air inlet connector 11 is inserted into the support cylinder 14, which provides stable support for the main pipe 10 and enhances the stability of the main pipe 10 installation.

[0039] In addition, a handle 18 is fixedly installed on the side of the device housing 1. The handle 18 has a U-shaped cross section, which makes it easy for the operator to push and pull the device. Together with the rollers 19 at the bottom, it further improves the ease of movement of the device.
[0040] It is worth noting that both ends of the branch pipe 3 are fixedly installed with end joints 33. The end joint 33 on the side closer to the main pipe 10 is connected to the main pipe 10 with a flange, while the end joint 33 on the other end is detachably connected to the external pipe, making the installation, disassembly and connection of the branch pipe 3 to the external pipe more convenient and quick.

A front cover plate 2 is detachably installed on the front side of the device housing 1 by multiple fastening screws. Multiple heat dissipation holes 20 are provided on the front cover plate 2. The multiple heat dissipation holes 20 are conducive to heat dissipation inside the device. At the same time, the detachable design of the front cover plate 2 facilitates the inspection and maintenance of the internal components of the device.
[0042] It is worth noting that the total pressure sensor 12, total flow sensor 13, electromagnetic proportional valve 30, branch pressure sensor 32, and branch flow sensor 31 are all electrically connected to the controller 15. The controller 15 can control the opening of the electromagnetic proportional valve 30 according to preset parameters or external commands to achieve intelligent automatic gas distribution. The touch screen display 171 is electrically connected to the controller 15 and is used to display the parameter information of each gas path and to set the parameters. The alarm module 172 is electrically connected to the controller 15. When abnormal gas path parameters are detected, the controller 15 controls the alarm module 172 to issue an alarm.
[0043] Finally, it should be noted that the components involved in this utility model, such as the total pressure sensor 12, total flow sensor 13, electromagnetic proportional valve 30, branch flow sensor 31, branch pressure sensor 32, controller 15, display 17, touch screen 171, alarm module 172, corresponding control program and control system, are all general standard parts or components known to those skilled in the art.

[0045] When the power is turned on, the total pressure sensor 12 and the total flow sensor 13 start to work. The gas parameters of each branch pipe 3 are set through the touch screen 171 of the display 17. After receiving the command, the controller 15 adjusts the opening of the electromagnetic proportional valve 30. The gas is diverted to the branch pipe 3 through the main pipe 10. The branch flow sensor 31 and the branch pressure sensor 32 monitor the parameters in real time and feed them back to the controller 15. The data is displayed on the touch screen 171.
[0046] If the parameters are abnormal, the alarm module 172 will issue an alarm. Adjustments need to be made via the touch screen 171.
