[0002] In recent years, gas safety accidents have occurred frequently at home and abroad. Gas safety has been highly valued by relevant departments. Therefore, the demand for gas safety electromagnetic cut-off valve products has increased sharply. The gas safety electromagnetic cut-off valve is applicable to pipeline natural gas, liquefied petroleum gas, and artificial gas, and is used in conjunction with a gas safety detection alarm. When the gas safety detection alarm detects gas leakage, it will drive the electromagnetic cut-off valve immediately to cut off the gas source to avoid the occurrence of safety accidents. After troubleshooting the cause of the failure and eliminating the failure, the lifting knob of the electromagnetic cut-off valve can be pulled up to resume gas supply and continue to ensure the safety of gas use. With the sharp increase in the demand for electromagnetic cut-off valves, the original production enterprises are rapidly expanding production capacity, and many new enterprises have also started production. The expansion of production capacity by old enterprises leads to unskilled new employees, insufficient equipment for the detection link, chaotic process management, and untraceable quality. The situation of new enterprises is even worse. All these factors result in the performance and quality of the electromagnetic cut-off valve, which is originally a gas safety product, not being guaranteed, thus posing a great potential safety hazard.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: This electromagnetic cut-off valve reset force and cut-off response detection device with high compatibility has the following advantages:

[0016] 1. If there is a unique barcode on the valve to be inspected and the inspection data needs to be bound to the barcode, in the manual loading and unloading production mode, only need to insert a USB interface barcode scanner into the USB socket of the USB interface, and turn on the barcode binding mode on the touch screen of the human-machine interaction display. After manually scanning the product to be inspected, the inspection table will allocate an inspection position for the currently scanned product to be inspected. The detection result display light of the electromagnetic cut-off valve at the allocated inspection position will flash to prompt. Only by placing the just-inspected product at the specified position and pressing the start button at the specified position can the inspection of the specified inspection position be started. Placing it at other inspection positions and pressing the start button cannot start the inspection. In this way, it can better ensure the accuracy of binding the inspection data to the barcode, greatly avoiding random binding in the manual mode. After inserting a USB flash drive into the USB port of the USB interface, the inspection data can be selected for data export and imported into the USB flash drive on the human-machine interaction display. Personnel are responsible for the work of scanning and placing the valve to be inspected, and subsequent work can be completely replaced by an automatic loading and unloading device. All inspection data can be bound to the product barcode, and all inspection data can be exported for analysis, which realizes quality traceability and can systematically analyze the inspection data to provide support for optimizing and improving product quality. Personnel only need to perform the work of scanning and picking up the valve to be inspected, and subsequent work can be completely replaced by an automatic loading and unloading device.

[0017] 2. After the scanned valve to be inspected is placed inside the corresponding valve body profiling fixture, the input end of the solenoid valve is electrically connected to the valve power supply plug located in the same valve body profiling fixture. After compressed air is introduced through the air supply joint pipe, it flows out through the middle holes of the air supply fixture block, air supply transfer fixture, and gasket. When the cylinder extends, it drives the entire air supply part to move, and the gasket will press tightly against the valve to be inspected to form a seal. The air flow then enters the solenoid valve through the middle hole. The jaws of the reset cap clamping mechanism open and move downward to the dropping position of the valve stem under the drive of the servo lifting module. The jaws of the reset cap clamping mechanism close to clamp the reset cap of the valve stem. Driven by the servo lifting module, the reset cap clamping mechanism moves upward to the valve stem pulling position. During this process, the pull pressure sensor will detect the force F required to pull up the valve stem. When the valve stem is at the pulling position, a group of sensors above the through-beam photoelectric sensor will be triggered, and the device will automatically supply power to the valve to make the valve stem drop to close the valve. During the dropping process of the valve stem, first, the signal of the group of sensors above the through-beam photoelectric sensor that was triggered disappears, and then the following group of through-beam photoelectric sensors detects the dropped reset cap of the valve stem and is triggered. The time difference between the disappearance and triggering of the signals of the two groups of sensors is collected and recorded as the valve closing response time t. Pull up the valve stem at least 3 times and record the force F required to pull up the valve stem and the valve closing response time t respectively. If it meets the requirements of industry standards, and at the same time according to the needs of the valve manufacturer, the number of detections can also be set to be greater than a certain value to realize the automatic detection of the reset force and cut-off response of the electromagnetic cut-off valve, reducing the labor intensity of personnel.

[0018] 3. For different models of products from the same valve manufacturer or different models of products from different valve manufacturers, compatibility can be achieved by replacing the body profiling tooling. The valve power supply plug is designed with pulse 6V, pulse 12V, pulse 24V, and AC 220V outputs. Each output voltage needs to be selected and then confirmed again on the touch screen of the human-machine interaction display to output the corresponding voltage, avoiding burning out the valve due to inappropriate voltage. For products of different models from different manufacturers, relevant voltages can also be bound to different model detection processes. After switching the detection model, only need to select the detection process corresponding to the model on the human-machine interaction display, and the device can automatically switch to output the corresponding voltage. For different models of products from the same valve manufacturer, different models of products from different valve manufacturers, or products of the same model but different batches with a large difference in valve stem height, only need to adjust the position of the quick-adjustment bracket on the first mounting bracket to achieve the reset cap drop detection for various models, batches, and products from different manufacturers. It is necessary to confirm by selecting on the device touch screen or by selecting the detection process corresponding to the product model to output the corresponding current. This innovation not only meets the compatibility of different voltage products but also greatly reduces the risk of burning out products due to mis-output voltage. For products with different models, different manufacturers, and different batches having differences in valve stem height, it can be quickly adjusted to adapt, reducing the equipment investment of valve manufacturers.

[0029] The working principle of a highly compatible electromagnetic cut-off valve reset force and cut-off response detection device provided by the present utility model is as follows: If there is a unique barcode on the valve to be inspected and the inspection data needs to be bound to the barcode, in the manual loading and unloading production mode, only need to insert a USB interface barcode scanner into the USB socket of the USB interface 6, and turn on the barcode binding mode on the touch screen of the human-machine interaction display screen 7. After manually scanning the product to be inspected, the inspection table will allocate an inspection position for the currently scanned product to be inspected. The electromagnetic cut-off valve inspection result display light 10 at the allocated inspection position will flash to prompt. Only by placing the just-inspected product at the specified position and pressing the start button 2 at the specified position can the inspection of the specified inspection position be started. Placing it at other inspection positions and pressing the start button 2 cannot start the inspection. In this way, it can better ensure the accuracy of binding the inspection data to the barcode and greatly avoid random binding in the manual mode. The inspection data can be exported and imported into the USB flash drive by selecting data export on the human-machine interaction display screen 7 after inserting the USB flash drive into the USB port of the USB interface 6. The inspected valve after scanning is placed inside the corresponding valve body profiling tooling 421. The input end of the solenoid valve 11 is electrically connected to the valve power supply plug 422 located in the same valve body profiling tooling 421. For products of different models from the same valve manufacturer or products of different models from different valve manufacturers, it can be compatible by replacing the valve body profiling tooling 421. The valve power supply plug 422 is designed with pulse 6V, pulse 12V, pulse 24V, and AC 220V outputs. Each output voltage needs to be selected and confirmed again on the touch screen of the human-machine interaction display screen 7 before the corresponding voltage can be output to avoid burning out the valve due to inappropriate voltage. For products of different models from the manufacturer, the relevant voltages can also be bound to different model inspection processes. After switching the inspection model, only need to select the inspection process corresponding to the model on the human-machine interaction display screen 7, and the device can automatically switch the output to the corresponding voltage. After compressed air is introduced through the air connection joint 415, it flows out through the middle holes of the air supply tooling block 412, the air supply transfer tooling 413, and the gasket 414. When the cylinder 411 extends, it drives the entire air supply part to move, and the gasket 414 will press tightly against the valve to be inspected to form a seal. The air flow then enters the solenoid valve through the middle hole. The claws of the reset cap clamping mechanism 55 open and move downward to the dropping position of the valve stem driven by the servo lifting module 52. The claws of the reset cap clamping mechanism 55 close to clamp the reset cap of the valve stem. Driven by the servo lifting module 52, the reset cap clamping mechanism 55 moves upward to the valve stem pulling position. During this process, the pull-pressure sensor 54 will detect the force F required to pull up the valve stem. At the valve stem pulling position, the upper group of sensors of the through-beam photoelectric sensor 433 will be triggered, and the device automatically supplies power to the valve to make the valve stem drop and close the valve. During the process of the valve stem dropping, first, the signal of the upper group of sensors of the through-beam photoelectric sensor 433 that was triggered disappears, and then the lower group of through-beam photoelectric sensors 433 detects that the dropped valve stem reset cap is triggered. The time difference between the disappearance and triggering of the signals of the two groups of sensors is collected and recorded as the valve closing response time t.Pull up the valve stem at least 3 times and record the force F required to pull up the valve stem and the valve closing response time t respectively. It meets the requirements of industry standards. At the same time, according to the needs of the valve manufacturer, the detection times greater than 3 can also be set, realizing the detection of the reset force of the solenoid valve and the detection of the cut-off response. For different models of products from the same valve manufacturer, or different models of products from different valve manufacturers, or products of the same model but different batches with a large height difference of the valve stem, only by adjusting the position of the quick-adjusting bracket 432 on the first mounting bracket 431, the detection of the reset cap falling off for products of multiple models, multiple batches, and different manufacturers can be realized.
