Description

Technical Field

[0001] The utility model belongs to the technical field of gas control, and in particular relates to an intelligent gas control system. Background Art

[0002] In many industrial production fields, there are a large number of equipment that require the use of gas in the production process. When these equipment are running, gas supply is crucial to ensure the smooth progress of the production process. However, the current gas control method mainly relies on manual operation, that is, after the equipment is shut down, workers are required to manually close the gas supply valve.

[0003] Currently, the production workshop is a complex and ever-changing environment. Workers need to take into account multiple tasks and links at the same time during the operation process. When the equipment is shut down, the complexity of the production site and the high-intensity work may distract the workers, making it easy for them to forget to turn off the gas valve due to negligence. When the workers forget to turn off the gas, the gas will continue to be supplied, resulting in a large amount of gas waste. Utility Model Content

[0004] The purpose of the present invention is to provide an intelligent gas control system to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent gas control system, comprising:

[0006] An electrical box, wherein a cover is hingedly connected to the surface of the electrical box, wherein a plurality of gas supply pipes are provided in the electrical box, and the two ends of the gas supply pipes are respectively an air inlet end and an air outlet end, and a solenoid valve for controlling the on and off of the gas supply pipes is provided on the surface of the gas supply pipes, and a timing control board for timing is provided on the surface of the electrical box cover, and the time for delaying gas shut-off is measured by the timing control board, so that the timing control board counts down to control the solenoid valve to close the gas supply pipe.

[0007] Preferably, an adjustment button is provided on the surface of the timing control panel.

[0008] Preferably, a socket is provided on the surface of the electrical box cover, and a power indicator light and a plurality of torsion switches are provided on one side of the socket.

[0009] Preferably, a mounting base plate is screwed into the electrical box, and a mutual inductor and an intermediate relay are provided on the surface of the mounting base plate.

[0010] Preferably, a filter is connected to the air inlet end of the air supply pipe through a bracket.

[0011] Preferably, the solenoid valve, socket, power indicator light, torsion switch, mutual inductor, and intermediate relay are all electrically connected to the timing control board.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: during the operation of the equipment in the workshop, the mutual inductor monitors the operating status signal of the equipment in real time. When the equipment stops, the mutual inductor detects the change in the operating signal and transmits this signal to the timing control board. After receiving the signal, the timing control board starts the internal timing program to start countdown. When the timing of the timing control board ends, that is, the delay time reaches the preset value, the timing control board sends a control signal to the intermediate relay to control the solenoid valve to close. After the solenoid valve is closed, the gas path of the gas supply pipeline is cut off, realizing the automatic gas shut-off function, thereby realizing intelligent gas control and the function of automatic gas shut-off with shutdown delay (the delay time is adjustable), thereby eliminating energy waste and reducing production costs.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The utility model provides Figure 1-3 An intelligent gas control system shown includes:

[0019] An electrical box 1, with an electrical box cover 2 hinged on its surface, a plurality of gas supply pipes 3 for gas supply are provided in the electrical box 1, and the two ends of the gas supply pipes 3 are respectively an air inlet end 4 and an air outlet end 5, and a solenoid valve 6 for controlling the on and off of the gas supply pipe 3 is provided on the surface of the gas supply pipe 3, and a timing control board 7 for timing is provided on the surface of the electrical box cover 2, and the time for delaying gas shut-off is timed by the timing control board 7, so that the timing control board 7 counts down to control the solenoid valve 6 to close the gas supply pipe 3.

[0020] The surface of the timing control board 7 is provided with an adjustment button 8, and the delay time can be preset on the timing control board 7 according to needs through the adjustment button 8.

[0021] A socket 9 is provided on the surface of the electrical box cover 2 , and a power indicator light 10 and a plurality of toggle switches 11 are provided on one side of the socket 9 .

[0022] A mounting base plate 12 is screwed into the electrical box 1, and a mutual inductor 13 and an intermediate relay 14 are provided on the surface of the mounting base plate 12. The intermediate relay 14 can enhance the driving ability of the control signal, ensuring that the solenoid valve 6 can reliably receive the control signal sent by the timing control board 7. The intermediate relay 14 can play a role of amplification and isolation during the signal transmission process.

[0023] A filter screen 16 is connected to the air inlet end 4 of the air supply pipe 3 through a bracket 15. The filter screen 16 can filter out solid impurities in the air supply pipe 3 with a diameter larger than its pore size, ensuring that clean gas can be discharged from the air outlet end 5 of the air supply pipe 3, thereby extending the service life of the gas-using equipment.

[0024] The solenoid valve 6 , the socket 9 , the power indicator light 10 , the toggle switch 11 , the mutual inductor 13 , and the intermediate relay 14 are all electrically connected to the timing control board 7 .

[0025] When the intelligent gas control system is operating normally, the socket 9 is connected to the external power supply to power the entire system. The power indicator light 10 lights up to indicate that the system is powered on. The toggle switch 11 is used to manually turn on or off the entire control circuit. After turning on, the system is in standby mode.

[0026] During the operation of the equipment in the workshop, the mutual inductor 13 monitors the operating status signal of the equipment in real time. When the equipment stops, the mutual inductor 13 detects the change of the operating signal and transmits this signal to the timing control board 7. After receiving the signal, the timing control board 7 starts the internal timing program, and the adjustment button 8 can be used to preset the delay time on the timing control board 7 according to the needs, so that the timing control board 7 can count down according to this setting. During the delay stage, the system maintains the gas supply, and the air inlet end 4 of the air supply pipe 3 is connected to the gas source, so that the gas can enter the system through the air outlet end 5 of the air supply pipe 3, and the solenoid valve 6 is in the open state under normal circumstances to ensure that the gas can pass smoothly.

[0027] When the timing of the timing control board 7 ends, that is, the delay time reaches the preset value, the timing control board 7 sends a control signal to the intermediate relay 14. After the intermediate relay 14 receives the signal, its contact state changes, thereby controlling the solenoid valve 6 to close. After the solenoid valve 6 is closed, the gas passage of the gas supply pipe 3 is cut off, and the automatic gas shut-off function is realized, thereby realizing intelligent gas control and the function of automatic gas shut-off during shutdown delay (the delay time is adjustable), thereby eliminating energy waste and reducing production costs.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
