标准范围
本文件适用于医用气瓶的销分度轭式阀门连接，工作压力最高可达200？巴或最大300巴的测试压力，或两者兼而有之。笔记？1？这种类型的连接主要用于小型气缸（5？l或以下）。笔记？2？在本文件中，由于其在技术气体领域中的普遍用途，使用了单位棒。然而，应该注意的是，bar不是国际单位制单位，压力的相应国际单位制单位是Pa（1 bar=105？Pa？=105 N/m2）。本文件规定:—？基本尺寸；—？轭式阀门连接的替代设计要求；—？出口连接孔和销的尺寸和位置。它还规定了气体和气体混合物出口连接的孔和销的尺寸和位置。
This document is applicable to pin-index yoke-type valve connections for medical gas cylinders, with a working pressure up to a maximum of 200 bar or test pressure up to a maximum of 300 bar, or both.NOTE 1 This type of connection is primarily used for small cylinders (5 l or below).NOTE 2 In this document the unit bar is used, due to its universal use in the field of technical gases. It should, however, be noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa (1 bar = 105 Pa = 105 N/m2).This document specifies:— basic dimensions;— requirements for alternative designs of the yoke-type valve connections;— dimensions and positions for the holes and pins for the outlet connections.It also specifies the dimensions and positions for the holes and pins for the outlet connections for gases and gas mixtures.
