The present invention proposes a high-pressure-resistant visual window suitable for optical measurement of injectors with wide nozzle angles. The stepped surface is matched with the quartz glass window, the axis of the quartz glass window is not perpendicular to the axis of the constant volume bomb body, the centering O-ring is used to radially position the quartz glass window, a bypass hole is provided in the sleeve, and the quartz glass window The entire side of the shell is communicated with the cavity of the constant volume bomb body through the bypass hole opened on the sleeve to balance the air pressure on the bottom and side of the quartz glass. Several short bolts lock the quartz glass window tightly between the sleeve and the end cover. between. When using PLIF method to study the spray combustion characteristics of multi-hole injectors, it is difficult to measure the spray of wide nozzle angle injectors due to the limited window area of ​​constant volume bombs, and it is difficult to obtain the window intensity if the window area is too large Guaranteed technical issues, improve service life and safety factor.

The invention discloses a frame carrier device and an LED display screen, and belongs to the technical field of LED display screens.
