控制阀国际标准体系和我国标准工作介绍国际电工委员会(International Electrotechnical Commission,)是根据1904年9月在美国召开的国际电气会议的决定，于1906年在伦敦成立的。

它是世界上最早的国际性电工标准化专门机构。

1947年加入国际标准化组织（ISO），作为它的电工部门。

1976年IEC和ISO达成协议，脱离ISO，成为在法律上独立于ISO 的组织，但在技术上仍与ISO进行密切合作。

IEC的目的是促进电气、电子工程等领域中标准化及有关问题的国际合作，增进国际间的相互了解，它的任务是制定国际标准以加强国际间的贸易。

国际电工委员会制订的标准在国际上占有重要的地位，许多国家把它作为自己的国家标准，或者与本国国家标准等同看待，在国际贸易中常常用IEC标准作为确定规格和产品质量的标准依据。

国际电工委员会目前设有80多个技术委员会，各技术委员会内可设分委员会，各技术委员会和分委员会下设若干工作组。

其中第65技术委员会（缩写TC65），名为“工业过程测量和控制（Industrial –Process Measurement and Control）,它成立于1969年，当时曾定名为“过程控制系统”，其任务为制订工业过程测量和控制系统与元件（即仪表）的国际标准，协调影响测量或控制系统匹配的有关标准化工作。

考虑到系统和系统元件的不同特点以及有利于工作的开展，在1973年TC65成立了两个分技术委员会：SC65A“系统考虑”（System Consideration）和SC65B “系统的元件”(Elements of Systems)。

SC65B的第9工作组（WG9）具体负责工业过程控制阀(Industrial Process Control Valves)的标准制订工作，其标准序号为IEC60534。

中国是IEC的正式成员国，积极参与了国际标准的制订工作，并在标准的贯彻、实施上取得了可喜成绩。

调节阀的⼝径计算控制阀的⼝径计算⼀、引⾔控制阀（调节阀）在⼯业⽣产过程⾃控系统中的作⽤犹如“⼿⾜”，其重要性是不⾔⽽喻的。

如何使⽤户获得满意的产品，除了制造上的精⼯细作外，还取决于正确的⼝径计算，产品选型，材料选⽤等，⽽其前提是要准确掌握介质、流量、压⼒、温度、⽐重等⼯艺参数和技术要求。

这是供需双⽅务必充分注意的。

本⼿册编制参考了国内外有关专业⽂献，也结合了我⼚长期来产品选型计算中的实际经验。

⼆、术语定义1、调节阀的流量系数流量系数Kv值的定义：当调节阀全开，阀两端压差为1×102Kpa（1.03巴）时，流体⽐重为1g/cm3的5℃～40℃⽔，每⼩时流过调节阀的⽴⽅⽶数或吨数。

Kv是⽆量纲，仅采⽤m3/h或T/h的数值。

Cv值则是当阀全开，阀前后压差1PSi，室温⽔每分钟流过阀门的美加仑数。

Cv=1.167 Kv。

确定调节阀⼝径的依据是流量系数Kv值或Cv值。

所以正确计算Kv（Cv）值就关系到能否保证调节品质和⼯程的经济性。

若⼝径选得过⼤，不仅不经济，⽽且调节阀经常⼯作在⼩开度，会影响控制质量，易引起振荡和噪⾳，密封⾯易冲蚀，缩短阀的使⽤寿命。

若⼝径选得过⼩，会使调节阀⼯作开度过⼤，超负荷运⾏，甚⾄不能满⾜最⼤流量要求，调节特性差，容易出现事故。

所以⼝径的选择必须合理，其要求是保证最⼤流量Qmax时阀的最⼤开度Kmax≤90%，实际⼯作开度在40—80%为宜，最⼩流量Qmin时的开度Kmin≥10%。

如兼顾⽣产发展，Kmax可选在70—80%，但必须满⾜Kmin≮10%。

对⾼压阀、双座阀、蝶阀等⼩开度冲刷厉害或稳定性差的阀则应⼤于20%~30%。

2、压差压差是介质流动的必要条件，调节阀的压差为介质流经阀时的前后压⼒之差，即ΔP=P1-P2。

在亚临界流状态下，压差的⼤⼩直接影响流量的⼤⼩。

调节阀全开压差是有控制的，其与整个系统压降之⽐（称S）是评定调节阀调节性能好坏的依据，如果流量波动较⼤时，S值应⼤些；波动⼩，也应⼩些。

控制阀细节分析之五－阀芯阀座李宝华摘要：包含阀芯阀座的阀内件（Valve Trim ）是控制阀的关键核心部件，直接影响控制阀的流量特性、流体调节和控制质量。

阀内件是与流体直接接触的阀内可拆卸的改变流通截面积和截流件导向等作用的零部件总称，包括典型截流件的阀芯(Plug)和阀座(Seat)、套筒(Cage)、阀杆(Stem)，以及减噪器(Flow divider)、抗空化气蚀部件(AC-trim)、导向(Guide)，等等。

从单座型控制阀(Globe valve)的阀芯阀座等阀内件的细节分析入手，看部分品牌厂家的阀芯阀座设计。

关键词：控制阀；阀内件；阀芯；阀座；细节分析；区别引言控制阀（Control valve ，国标GB/T 17213.1-1998定义为控制阀，国内旧称调节阀）是终端控制元件，决定着过程控制是否及时有效，在整个控制回路中较为重要但又是长期以来技术比较薄弱的环节。

一个控制系统的控制质量受到组成系统各环节的影响，更取决最薄弱环节的影响，控制阀虽然相对控制系统和过程仪表而言略显简单，但在工业生产过程对控制要求及安全性不断提高的情况下，其必要性、重要性以及在回路中较高的故障频次已引起业内注意。

控制阀的生产厂家众多，造成控制阀品种多、规格多、参数多，质量参差不齐。

不同厂家的同类型控制阀的设计差异、技术特点和应用情况如何？应是大家关注的问题。

本文着重对目前在用量最大、多数厂家都在生产的单座型控制阀(Globe valve)做一些细节分析。

以部分知名品牌控制阀为例，对阀内件的阀芯阀座的技术细节进行分析探讨。

阀内件（Valve Trim）国标《工业过程控制阀 第1部分：控制阀术语和总则》GB/T17213.1－1998（等效IEC 60534-1）对阀内件（Valve Trim ）的定义是：阀内接触被控流体的部件，例如截流件、阀座、套筒、阀杆、以及连接阀杆与截流件的部件等。

阀体、阀盖、底法兰和垫圈不属于阀内件。
