一种缺陷深度测量装置
By designing a defect depth measuring device that includes a main body, a main piston, and a measuring piston, and using the cylinder chamber area ratio for equal magnification and zeroing mechanism calibration, the problem that existing tools cannot accurately measure the depth of volumetric defects in long-distance oil and gas pipelines has been solved, and high-precision defect depth measurement has been achieved.

Abstract
本发明公开了一种缺陷深度测量装置，包括主体、主活塞和测量活塞，主体内竖向设有主缸室和测量缸室，且测量缸室的下端与主缸室的上端连通，主活塞安装在主缸室内，测量活塞安装在测量缸室内，主缸室和测量缸室断截面的面积分别为S1和S2，且S1>S2，且测量缸室旁沿其上下方向设有长度刻度，主缸室内位于主活塞的上方以及测量缸室内位于测量活塞的下方填充有液体，主活塞的下端中部竖直设置有一个下端贯穿主体下端的测量探针，如此可将测量探针的下端伸入到缺陷内，测量时测量活塞的位移量是将主活塞向下移动的位移量进行等倍的放大(倍数为S1 / S2)，如此可对缺陷深度进行精确的测量。
