Valve Types Terminology English-Chinese Comparisons (1)
阀门是一种供控制流体进出的设备，有许多不同种类的阀门可用于不同类型的流动。虽然一些种类的阀门往往会被所处位置或用途而被命名，但大多数阀门种类常常会以英文或拉丁文为基础，根据他们的功能和结构来命名。此文档将针对英文和拉丁文阀门类型术语进行中文对照：
Valves are devices for controlling the passage of fluids in and out, and there are many different types of valves that can be used for different types of flows. While some types of valves are often named based on their location or use, most valve types are often named based on their function and structure, either in English or Latin. The following document will provide Chinese equivalents of English and Latin valve type terminology:
1. 蝶形阀——Butterfly valve
蝶形阀是一种不密封的阀门，由一块板片作为阀门和管道之间的可调节隔室，板片可通过一个轴杆上有诸如旋钮的控制元件的调节。这种阀门可广泛用于控制高温、高压的流体，此外，它们安装价格低廉，维护也不昂贵。
1. Butterfly Valve - Butterfly valves are non-sealed valves, which consist of a plate as an adjustable chamber between the valve and pipe. The plate can be regulated through a controllable element such as a knob on an axle. These valves are widely used to control high temperature and pressure fluids, and they are low-cost to install and not costly to maintain.
2. 球形阀——Ball valve
球形阀由一个穿放在手柄上的旋转球体，其位置可以精确控制流量，从而控制流量。球形阀常用于燃气、水和汽油及其他油脂类非有机液体的控制。此外，它也经常用作调节阀来控制流量，以及消防保护防止意外的关闭。
2. Ball Valve - Ball valves consist of a rotating ball that is placed on a handle, and its position can be accurately controlled to control the flow rate. Ball valves are commonly used to control gases, water, petrols, and other oil-based non-organic fluids. Additionally, they are also frequently used as regulators to control the flow rate, and in fire protection to prevent accidental shut-downs.
3. 闸门阀——Gate valve
它是一种有棱和牙边覆盖阀座的阀门，可以全闭或全开，泄漏量也较少。这些阀门被用于在应用中宰杀服务，并具有可调闸板以控制流动的能力。这种阀门的安装也不昂贵，而且，可以应对各种低压，非危险的工作。
3. Gate Valve - Gate valves are valves that have protrusions and teeth covering a valve seat, that can be completely closed or open, with a low leak rate. These valves are used for shutdown services in applications, and have adjustable gate plates to control the flow. The installation of these valves is not expensive either, and they can handle a variety of low-pressure, non-hazardous work.
4. 膜片阀——Diaphragm valve
膜片阀是一种由一个弹力膜片、夹紧块和调节元件组成的双开式或三开式可调节阀门。它可以控制粉状芯片、液体和气体的流量，其密封性能也极佳，可以精确控制流量，以及抗磨损和腐蚀性能强。
4. Diaphragm Valve - Diaphragm valves are double-open or three-way adjustable valves composed of a resilient diaphragm, clamping blocks, and regulating elements. It can control the flow of powders, liquids, and gases, and has good sealing performance, can precisely control the flow rate, and has strong wear resistance and corrosion resistance.
