本文件规定了真空技术中使用的夹紧式快速释放联轴器的尺寸，以及与这些联轴器相关的O形圈及其托架的尺寸，用于确保真空密封性。 注意，为联轴器直径保留的尺寸确保了快速释放联轴器与ISO 1609[1]中规定的相应真空法兰的兼容性。

This document specifies the dimensions of the clamped-type quick-release couplings used in vacuum technology, as well as those of the O-rings and their carriers associated with these couplings, used to ensure vacuum tightness. NOTE The dimensions retained for the coupling diameter ensure the compatibility of the quick-release coupling with the corresponding vacuum flanges specified in ISO 1609^[1].
