Study of Valve Seat Bubble Leakage Detection and Laser Alignment Device
To find out the principle and measurement accuracy of laser alignment applied to valve seat bubble leakage detection,and to improve the efficiency and accuracy of valve seat bubble leakage detection,the valve seat bubble leakage detection and laser alignment device is studied.Through the design of the valve seat bubble leakage detection device based on laser alignment,analysis of the current situation and scientific experiments,the measurement stability of the device,the relationship between the bubble formation rate or leakage rate and the volume of individual bubbles,the accuracy of the relationship between the number of bubbles specified in the domestic and foreign standards and the volume of the gas leakage conversion,and so on,has been studied in depth.It concludes that the bubble leakage detection device based on laser alignment has superior measurement stability,and the bubble formation rate is proportional to the volume of a single bubble.Based on the conclusions of the study,the irrationality of the conversion relationship between the number of bubbles and the volume of gas leakage in the domestic and foreign standards and the application suggestions are put forward.
