小型医用气瓶 — 销钉索引轭式阀门连接

[中文适用范围]： 本文件适用于医用气瓶的销钉索引轭式阀门连接，工作压力最大为 200 bar，测试压力最大为 300 bar，或两者兼而有之。注1：这种连接方式主要用于小型气瓶（5升或以下）。注 2：在本文件中，由于其在工业气体领域的普遍使用，因此使用单位 bar。但应注意，bar 不是 SI 单位，压力对应的 SI 单位是 Pa（1 bar = 105 Pa = 105 N/m2）。本文件规定： ——基本尺寸； ——轭式阀门连接替代设计的要求； — 出口连接的孔和销钉的尺寸和位置。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。 [外文原描述]： 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 = 10 5 Pa = 10 5 N/m 2 ). 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.
