AI Technical Summary
Existing technology cannot accurately measure the deflection angle of the dual valve plates in the bypass valve, which may lead to air leakage problems during assembly.
A fixing fixture comprising a slider, a bracket, a guide sleeve, a push rod, and a push head is designed to stably fix the bypass valve through a limit pin and a knob screw, allowing for individual measurement of the deflection angle of each valve plate.
It enables quick clamping and accurate measurement of valve plate deflection angle, avoiding assembly errors caused by mutual interference of valve plates.
