Valve trim types
阀门剪裁类型
Valve trim is an important component of a valve, as it is the component that actually controls the flow of fluid. Valves are available with different trim types, depending on the type of service and flow characteristics desired for a particular application. Generally speaking, the trim types are divided into three main categories: Simple Ported, Multi Ported, and Balanced Trim.
阀门剪裁是阀门的重要组成部分，因为它实际上控制流体流动。根据特定应用中所需的服务类型和流动特性，可以提供不同的剪裁类型的阀门。一般而言，剪裁类型分为三大类：简单端口，多端口和平衡剪裁。
Simple Ported Trim
简单端口剪裁
Simple ported trim is perhaps the most common type of trim found in industrial valves. As the name implies, this trim type consists of several ports or holes that can be opened and closed to control the flow of fluid. Most simple ported trim designs feature two ports, one located at the top and one at the bottom. The ports are connected via a valve stem, allowing the flow of fluid to be controlled.
简单端口剪裁可能是工业阀门中最常见的剪裁类型。顾名思义，这种剪裁类型由几个口或孔组成，可以开启和关闭以控制流体的流动。大多数简单端口剪裁设计都有两个口，一个位于顶部，一个位于底部。口之间通过阀芯相连，允许控制流体的流动。
Multi Ported Trim
多端口剪裁
Multi-ported trim is a more advanced type of trim, as it features multiple ports that can be opened and closed simultaneously to control the flow of fluid. This type of trim is generally used in higher-pressure applications, as it is better suited to regulating flow under greater pressure. Multi-ported trim typically features three or more ports, allowing for precise control of flow in both directions.
多端口剪裁是一种更高级的剪裁，因为它具有多个可以同时开启和关闭以控制流体流动的口。这种剪裁通常用于压力较高的应用，因为它更适合在更高压力下调节流量。多端口剪裁通常具有三个或三个以上的口，允许精确控制双向流量。
Balanced Trim
平衡剪裁
Balanced trim is a type of trim design used in applications where the pressure drop across the valve must be kept to a minimum. This type of trim is designed to evenly distribute the pressure across the entire valve, allowing for a more efficient flow of fluid through the valve. Balanced trim designs typically feature several ports located around the circumference of the valve, allowing for the even distribution of pressure.
平衡剪裁是一种用于压力降对阀门必须保持最小的应用中的剪裁设计。这种剪裁的设计是为了均匀地在整个阀门上分布压力，从而使流体在阀门中流动得更有效率。平衡剪裁设计通常具有位于阀门周围的几个口，允许均匀地分布压力。
These are the three main types of valve trim. When selecting the trim for a particular application, it is important to consider the desired flow characteristics and the type of service the valve will be used for. The type of trim used should be chosen based on these factors in order to ensure that the valve functions correctly and efficiently.
这就是三种主要的阀门剪裁。在为特定应用选择剪裁时，重要的是考虑所需的流动特性以及阀门用于的服务类型。应根据这些因素选择使用的剪裁类型，以确保阀门正确有效地工作。
