[0042] Example 1

[0043] During routine repair and maintenance work in production workshops, operators lacking pneumatic knowledge can only determine whether cylinders are leaking by groping on the spot, which is not possible to quickly and easily detect cylinder internal leaks. In addition, production sites often need to test gas line pressure to determine whether the gas line pressure meets production requirements. Existing testing devices are complex in structure, the testing process is long and cumbersome, and it is impossible to quickly and accurately determine the gas line pressure of the pipeline.

[0044] In view of this, an embodiment of the present invention provides a pneumatic detection device, including: a power supply 100, a solenoid valve 200, a connector 300 and a pressure gauge 400, the solenoid valve 200 is connected between the power supply 100 and the connector 300, the end of the connector 300 is connected to the pressure gauge 400, and the connector 300 is used to connect to the air path component to be detected.

[0045] To test a cylinder for internal leakage, supply compressed air normally to one end of the cylinder and connect connector 300 to the other end. Turn on power supply 100. After a while, disconnect the circuit between power supply 100 and solenoid valve 200 and check whether the value on pressure gauge 400 changes. After testing one end, repeat the above steps and test the other end. If the value on pressure gauge 400 remains zero at both ends, the cylinder is leaking. If the value on pressure gauge 400 on either end changes, the cylinder is leaking and requires prompt repair or replacement.

[0046] When testing the gas line pressure, the connector 300 is connected to one end of the pipeline, the power supply 100 is turned on, and the value of the pressure gauge 400 is checked to quickly and accurately determine whether the gas line pressure of the pipeline meets the production requirements.

[0047] Furthermore, the pneumatic testing device can also test the pressure-reducing function of a compressed air filter pressure reducing valve. To perform the test, connect connector 300 to the front section of the compressed air filter pressure reducing valve, turn on power supply 100, and check the value on pressure gauge 400. Then, connect connector 300 to the rear section of the compressed air filter pressure reducing valve, turn on power supply 100, and check the value on pressure gauge 400. The difference between the two readings on pressure gauge 400 represents the reduced pressure of the compressed air filter pressure reducing valve, allowing a quick assessment of whether the pressure-reducing function of the compressed air filter pressure reducing valve meets the requirements.

[0048] The pneumatic detection device has a simple structure and is easy to use. It can quickly determine whether the functions of common gas path components meet production requirements, thus quickly resolving gas path problems on the production line. It can be used for daily maintenance of gas path components, thereby improving the efficiency of production equipment.

[0049] In an optional manner of this embodiment, a time relay 500 is connected between the solenoid valve 200 and the power supply 100 .

[0050] See Figure 1 The time relay 500 can set a power-off time during the detection of gas path components. When the power-off time is reached, the time relay 500 disconnects the circuit of the solenoid valve 200, and then the reading of the pressure gauge 400 is observed.

[0051] Furthermore, the time relay 500 is provided with a time indicator light 510 , which is used to display the on / off status of the circuit between the power supply 100 and the solenoid valve 200 .

[0052] See Figure 2 The time indicator light 510 can display the on / off status of the circuit between the power supply 100 and the solenoid valve 200. When the power-off time is reached, the time indicator light 510 lights up, thereby clearly indicating to the operator to perform the reading operation.

[0053] Furthermore, the power supply 100 is provided with a power knob 110 , which is used to turn the power supply 100 on or off.

[0054] See Figure 2 The power knob 110 can be turned on to turn on the power supply 100 during the test, and can be turned back to turn off the power supply 100 after the test is completed.

[0055] Furthermore, the power supply 100 is provided with a power indicator light 120 , which is used to display the on or off status of the power supply 100 .

[0056] See Figure 2 When the power supply 100 is turned on, the power indicator light 120 lights up, clearly indicating to the detection personnel that the power supply 100 is turned on. When the power supply 100 is turned off, the power indicator light 120 goes out, clearly indicating to the detection personnel that the power supply 100 is turned off.

[0057] In an optional manner of this embodiment, the solenoid valve 200 is provided with a solenoid valve knob 210 , and the solenoid valve knob 210 is used to open or close the solenoid valve 200 .

[0058] See Figure 2 The solenoid valve 200 is a two-position five-way solenoid valve. The solenoid valve knob 210 can adjust the open or closed state of the solenoid valve 200. When performing a test, the solenoid valve 200 is opened by rotating it, and after the test is completed, the solenoid valve 200 is closed by rotating it again.

[0059] Furthermore, the solenoid valve 200 is provided with a solenoid valve indicator light, which is used to display the open or closed state of the solenoid valve 200.

[0060] When the solenoid valve 200 is open, the solenoid valve indicator light is on, clearly indicating to the inspector that the solenoid valve 200 is open. When the solenoid valve 200 is closed, the solenoid valve indicator light is off, clearly indicating to the inspector that the solenoid valve 200 is closed.

[0061] In an optional manner of this embodiment, the connector 300 is a three-way quick connector.

[0062] See Figure 1The first end of the connector 300 is connected to the solenoid valve 200, the second end is connected to the pressure gauge 400, and the third end is used to connect to the gas path component to be tested.

[0063] In an optional manner of this embodiment, the pressure gauge 400 is an electronic pressure gauge.

[0064] The electronic pressure gauge can quickly and accurately display the value during testing, informing the tester of the real-time gas line pressure.

[0065] It should be noted that the power supply 100, solenoid valve 200, connector 300, time relay 500 and pressure gauge 400 are all arranged in the box and are in a closed state during detection, thereby ensuring the accuracy of the detection value. The box is provided with a detection opening, and the end of the connector 300 connected to the gas circuit component to be detected extends out of the detection opening to facilitate connection with the corresponding gas circuit component to be detected. A controller can also be provided in the box, and the controller is connected to the pressure gauge 400 signal. A buzzer is provided outside the box, and the buzzer is connected to the controller signal. When detecting whether the cylinder has internal leakage, if the value of the pressure gauge 400 changes during the detection, the buzzer will sound to remind the detector that the cylinder has internal leakage and needs to be repaired or replaced in time.

[0066] The following describes how to use the pneumatic detection device:

[0067] The pneumatic detection device can detect whether the cylinder has internal leakage. During the test, supply compressed air normally to one end of the cylinder and connect the connector 300 to the other end of the cylinder. Turn the power knob 110 to turn on the power supply 100 and set the power-off time of the time relay 500. After the time is up, the time relay 500 will disconnect the circuit between the power supply 100 and the solenoid valve 200, and the time indicator light 510 will light up. You can check whether the value of the pressure gauge 400 has changed. After the test on one end is completed, repeat the above operation and test the other end of the cylinder. If the values ​​of the pressure gauges 400 at both ends are always zero, it means that there is no internal leakage in the cylinder. If the value of the pressure gauge 400 at either end changes, it means that there is an internal leakage in the cylinder and it needs to be repaired or replaced in time.

[0068] The pneumatic detection device can also detect the gas line pressure. During the detection, the connector 300 is connected to one end of the pipeline, the power supply 100 is turned on, and the value of the pressure gauge 400 is checked to quickly and accurately determine whether the gas line pressure of the pipeline meets the production requirements.

[0069] The pneumatic testing device can also test the pressure-reducing function of a compressed air filter pressure reducing valve. To perform the test, connect connector 300 to the front section of the compressed air filter pressure reducing valve, turn on power supply 100, and check the value on pressure gauge 400. Then, connect connector 300 to the rear section of the compressed air filter pressure reducing valve, turn on power supply 100, and check the value on pressure gauge 400. The difference between the two readings on pressure gauge 400 represents the reduced pressure of the compressed air filter pressure reducing valve, allowing a quick assessment of whether the pressure-reducing function of the compressed air filter pressure reducing valve meets the requirements.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
