[中文适用范围]： 该国际标准规定了井下安全阀（SPA）的最低要求。它涵盖了井下安全阀，包括所有设置公差和/或间隙的组件，这些组件可能影响 SPA 的性能或互换性。包括维修操作和连接至流量控制或其他设备的连接，但不涉及与井筒管道的连接。 注：限制：井下安全阀是一种紧急安全装置，不用于生产作业，如降低产量/注入、停止生产，或用作回注阀。 翻新作业不在本国际标准的范围内（见第 8 条）。 [外文原描述]： This specification provides the requirements for subsurface safety valves (SSSVs), annular safety valves (ASVs) and the secondary tools as defined herein necessary to operate the features included within them, including all components that establish tolerances and/or clearances that may affect performance or interchangeability of the SSSV or ASV components. It includes repair operations and the interface connections to control conduits and/or other equipment but does not cover the connections to the primary well conduit. NOTE The SSSV and ASV are emergency fail-safe devices. The products covered within this specification are installed and operated to the requirements of API Recommended Practice 14B. This specification does not cover installation, maintenance, control systems for SSSV or ASV, computer systems, and control conduits not integral to the downhole SSSV or ASV. Also not included are products covered under API 6A, API 11D1, API 14L, API 17C, API 19G, API 19AC, API 19V
