Description

Technical Field

[0001] The invention relates to the technical field of solenoid valve production, in particular to an airtightness detection device for solenoid valve production which is easy to connect. Background Art

[0002] The easy-to-connect airtightness detection device for solenoid valve production is a device widely used in the field of industrial automation. Its main function is to ensure the safe operation of the equipment and to detect possible safety hazards as early as possible.

[0003] When gas flows in the pipeline, eddy currents are easily generated, resulting in energy loss and pressure fluctuations in the gas, making it difficult for the gas to enter the solenoid valve stably. Some equipment finds it difficult to promote chemical reactions between gases at the same time, resulting in low efficiency in the solenoid valve air tightness detection. When the gas enters the detection device, if the flow rate is too large, gas shock may occur, resulting in the generation of bubbles and increasing the possibility of gas shock.

[0004] In addition: when using the existing air tightness detection device for solenoid valve production, it is difficult to make the connecting pipe more accurately transmit the pressure to the pressure sensor when it is under gas pressure, which may cause the connecting pipe to expand or contract excessively, making it difficult for the pressure sensor to detect the actual pressure change, reducing the accuracy of air tightness detection, and it is difficult to perform vibration detection on some equipment while supporting it. If the connecting pipe vibrates abnormally, it may mean that there is a leak at the connection between the solenoid valve and the connecting pipe, resulting in unstable gas flow and affecting the air tightness detection result;

[0005] Finally: When the existing airtight detection device for solenoid valve production is in use, it is difficult to control the operation of the vibration detection part, which may cause the vibration detection part to work for a long time and become fatigued, thereby reducing the service life of the vibration detection part and increasing the downtime of the airtight detection device for solenoid valve production; the existing technology is difficult to switch the control switch, and the same control switch may be repeatedly squeezed, and the practicality is relatively simple.
