摘　　要：气瓶圆锥螺纹用于气瓶的瓶口与瓶阀连接,螺纹的强度及密封性是保证气瓶质量的关键环节之一,也是密封相对薄弱的环节。气瓶螺纹的质量与企业安全生产和人民生活安全密切相关。因此,详细了解、正确使用、准确检测气瓶锥螺纹量规是非常必要的。本文主要介绍了用中图测长机检测气瓶圆锥螺纹塞规、环规中径的方法和步骤,并对其基本牙型参数作了简单介绍。The conical thread of gas cylinders is used to connect the bottle mouth and valve of gas cylinders.The strength and sealing of the thread are one of the key links to ensure the quality of gas cylinders,and it is also a relatively weak sealing link.The quality of gas cylinder threads is closely related to the safety of enterprise production and people's lives.Therefore,it is necessary to have a detailed understanding,correct use,and accurate detection of cylinder taper thread gauges.This article mainly introduces the method and steps of using the Zhongtu length measuring machine to detect the diameter of the conical thread plug gauge and ring gauge of gas cylinders,and provides a brief introduction to their basic tooth shape parameters.
