API 598 第 10 版 2016 阀门的检查与试验 Valve Inspection and Testing API 598 -- 2016 1. Scope 范围 1.1. This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g. ceramic), and metal-to-metal-seated valves of the gate, globe, plug, ball, check, and butterfly types. Resilient seats are considered to be: 本标准包含了弹性阀座、非金属阀座（例如陶瓷）以及金属对金属阀座的闸阀、截止阀、旋塞阀、球 阀、止回阀和蝶阀等类型阀门的检查、检验、补充检验和压力试验要求。弹性阀座包括以下几种： a) soft seats, both solid and semisolid grease type (e.g. lubricated plug); 软密封阀座，固体和半固态润滑脂类（如油封旋塞阀） b) combination soft and metal seats (e.g. laminated seat rings); 软密封和金属密封的组合（如层叠式座圈） c) any other type of seat material designed to meet resilient seat leakage rates as specified in Table 5. 设计满足表5 规定的弹性密封泄漏率的其它任何阀座材料。 API Standard 598 supplements the API standards that reference it, but it may also be applied to other types of valves by agreement between the purchaser and the valve manufacturer. Reference Annex A for information to be specified by the purchaser. API 598 标准是对引用它的API 标准的补充，若买方和阀门制造商经过协商，API 598 亦可用于其它 类型阀门。 1.2. The inspection requirements pertain to examinations and testing by the valve manufacturer and any supplementary examinations that the purchaser may require at the valve manufacturer’s plant. The test requirements cover both required and optional pressure tests at the valve manufacturer’s plant or at a facility mutually agreeable to both the manufacturer and the purchaser. 检查要求适合于阀门制造商的检验和试验和买方可能要求在阀门制造商厂内进行的任何补充检验。试 验要求包括了在阀门制造商厂内或在制造商和买方共同商定的工厂的需要和可选的压力试验。 1.3. The following tests and examinations are specified in this standard: 本标准规定的试验和检验项目如下： a) shell test, 壳体试验 b) backseat test, 上密封试验 c) low-pressure closure test, 低压密封试验 d) high-pressu
