基于功能的同义词：直角回转阀

基于密封性能的名称：零泄漏阀 特定设计配置及其具体名称, 基于驱动方式的术语, ，以及 行业特定俚语及口语表达 **for ball valves across different contexts.**.

**The Direct Answer: Common Alternative Names for a Ball Valve**

**If you need the shortest possible answer to “What is another name for a ball valve,” the following three are the most universally recognized and widely accepted alternatives:**

1. **Quarter-Turn Valve** **– A** **functional descriptor**. **. Because a ball valve operates with a 90-degree rotation to open or close, this name highlights its fundamental distinction from multi-turn valves such as gate or globe valves.**.

2. **Shut-off Valve** **– An** **application-based name**. **. Since ball valves are primarily used for on-off isolation rather than precise throttling, engineers frequently refer to them simply as “shut-off valves” when emphasizing their isolation function.**.

3. **Ball Cock** **– A** **historical/colloquial term**. **. In earlier British English and specific plumbing contexts, small ball valves were often called “ball cocks” (though in modern industrial usage, this term more specifically denotes a float-operated valve).**.

**In-Depth Analysis: Context-Specific Alternative Names**

**Alternative names for ball valves are not arbitrary; they derive from** **structural features**, **actuation methods**, **, or** **industry application habits**.

**1. Function-Based Synonym: Quarter-Turn Valve**

1. **Context:** **Engineering specifications, general valve classification.**.

2. **Background:** **API and ASME standards classify valves as either multi-turn or part-turn (quarter-turn).**. **Quarter-turn** **is a shared attribute of ball valves, butterfly valves, and plug valves. When someone specifies “a stainless steel quarter-turn valve for this location,” they are almost certainly referring to either a ball valve or a butterfly valve.**.

**2. Seal-Performance Based Name: Bubble-Tight Valve**

1. **Context:** **Quality test reports, gas service applications.**.

2. **Meaning:** **The unique floating or trunnion-mounted ball design enables ball valves to achieve excellent shutoff performance under both low and high pressure, with zero bubble passage during seat leakage tests. When specifying valves for gas pipelines, engineers may explicitly request “bubble-tight shut-off valves.”**”

**3. Specific Design Configurations and Their Specific Names**

**4. Actuation-Based Terminology**

1. **Actuated Ball Valve:** **When a valve is not manually operated by a lever, it is often no longer referred to simply as a “ball valve” in control narratives. It becomes part of a** **MOV (Motor Operated Valve)** 或 **POV (Pneumatic Operated Valve)** **package.**.

**5. Industry-Specific Slang and Colloquialisms**

1. **Plumbing / Residential Sector:**

   1. **Stop Cock:** **Specifically refers to a small, right-angle ball valve with a lever handle typically found under a toilet or sink.**.

   2. **Isolator:** 在英国和澳大利亚的锅炉维护手册中，技术人员通常将管道上的小型球阀称为“隔离阀”。”

   3. 杠杆阀： 非技术用户通常根据其外观（长杠杆手柄）来命名该阀门，以区别于圆形手柄的闸阀。.

2. 液压/气动领域：

   1. 球式截止阀： 高压液压球阀的常见商业名称。.

3. 工业自动化领域：

   1. 开关型终端执行元件： 虽然并非球阀专属，但在DCS（分布式控制系统）逻辑图中，一个 自动化球阀 用于隔离时被归类为 开关型终端执行元件.

常被混淆的“伪别名”（重要区分）

并非所有名称中带有“球”字的阀门都是同一种类型。以下术语常被误认为是球阀的同义词，但它们指的是不同的设备：

为何有如此多的名称？

这种命名多样性源于 功能导向 的工程沟通需求。.

1. 当讨论 管道布局空间, 时，工程师称之为 **Quarter-Turn Valve** （强调紧凑安装）。.

2. 当 采购关注成本和重量, 时，他们会比较 杠杆操作阀 与手轮操作阀。.

3. 当 维护团队编写工作许可, 时，他们将其标记为 球阀隔离阀 （强调安全隔离）。.

总结：
如果您听到“四分之一转截止阀”或“杠杆球旋塞,”，它们指的是球阀。对于专业文档，, Ball Valve 仍是首选术语。使用 四分之一转球阀 以强调操作便利性，以及 气泡级密封截止球阀 以突出密封完整性。.
