常州凯文电动装置与阀门选型手册

对于执行机构的输出要大于阀门的负荷，且合理匹配。

检查标准组合时，要考虑阀门所规定的允许压差是否满足工艺要求。

大压差时要计算阀芯所受的不平衡力。

要考虑执行机构的响应速度是否满足工艺操作要求，尤其是电动执行机构。

气动执行机构相比电动执行机构有何特点，输出形式：电动驱动源为电力简单方便，推力、扭矩大，刚度大。

但结构复杂，可靠性差。

在中小规格上比气动的贵。

常用于无气源或不需严格防爆、防燃的场合。

电动执行机构有角行程、直行程、和多回转三种输出形式。

角行程类阀的切断压差较大，是因为介质在阀芯或阀板上产生的合力对转动轴产生的力矩非常小，因此，它能承受较大的压差。

蝶阀，球阀是最常见的角行程类阀门。

单密封类的调节阀如单座阀、高压阀、无平衡孔的单密封套筒阀需进行流向选择。

流开、流闭各有利弊。

流开型的阀工作比较稳定，但自洁性能和密封性较差，寿命短；流闭型的阀寿命长，自洁性能和密封性好，但当阀杆直径小于阀芯直径时稳定性差。

单座阀、小流量阀、单密封套筒阀通常选流开，当冲刷厉害或有自洁要求时可选流闭。

两位型快开特性调节阀选流闭型。

除单、双座阀及套筒阀外，具有调节功能的阀：隔膜阀、蝶阀、O型球阀（以切断为主）、V型球阀（调节比大、具剪切作用）、偏心旋转阀都是具有调节功能的阀。

计算与选型比较而言，选型要重要得多，复杂得多。

因为计算只是一个简单的公式计算，它的本身不在于公式的精确度，而在于所给定的工艺参数是否准确。

双座阀阀芯的优点是力平衡结构，允许压差大，而它突出的缺点是两个密封面不能同时良好接触，造成泄漏大。

人为地、强制性地用于切断场合，显然效果不好，即便为它作了许多改进（如双密封套筒阀），也是不可取的。

双座阀小开度工作时容易振荡:对单芯而言,当介质是流开型时，阀稳定性好；当介质是流闭型时，阀的稳定性差。

双座阀有两个阀芯，下阀芯处于流闭，上阀芯处于流开。

这样，在小开度工作时，流闭型的阀芯就容易引起阀的振动，这就是双座阀不能用于小开度工作的原因所在。

控制阀选型原则调节阀的节流原理和流通能力当流体经过调节阀时,由于阀芯、阀座间流通面积的局部缩小，形成局部阻力,使流体在此处产生能量损失,这个损失的大小通常用阀前后的压差来表示. 当调节阀口径一定，即调节阀接管截面积A一定，且P1—P2不变时，阻力系数ζ减小,流量Q则增大，反之ζ增大则Q减小，所以调节阀的工作原理就是由输入信号的大小、改变阀芯的行程，从而改变流通面积达到调节流量的目的。

C称为流通能力，与阀芯、阀座的结构、阀前后的压差、流体性质等因素有关.必须在规定了—定的条件后，再描述调节阀的流通能力。

我国所用流通能力C的定义为:在调节阀全开，阀前后压差为1kgf／cm2，介质重度为1gf／cm3时,流经调节阀的流量数。

例如:一个C值为32的调节阀就是表示当阀全开,阀前后压差为1kgf／cm2时,每小时能通过的水量为32m3。

一、由工艺或用户提供相关资料:1、被控制流体的种类：（3种)液体、气体和蒸汽对于液体应考虑黏度的修正，当液体粘度过高时，其雷诺数下降,改变了流体的流动状态，在计算控制阀流通能力时,必须考虑粘度校正系数。

对于气体，应该考虑其可压缩性。

对于蒸汽，要考虑饱和蒸汽和过热蒸汽。

2、流体的温度、压力根据工艺介质的最大工作压力来选定控制阀的公称压力时，必须对照工艺温度条件综合选择,因为公称压力是在一定基准温度下，依据强度确定的，其允许最大工作压力必须低于公称压力。

例如:对于碳钢阀门，当公称压力PN1.6MPa,介质温度在200℃时，最大耐压力为1。

6 MPa；当250℃时，最大耐压力为1。

5 MPa;当400℃时,最大耐压力为0。

7 MPa。

对于压力调节系统,还要考虑其阀前取压、阀后取压和阀前后压差,在进一步来选择阀的形式。

3、流体的粘度、密度和腐蚀性根据流体的粘度、密度和腐蚀性来选择不同形式的阀门以便满足工艺的要求。

对于高粘度、含纤维介质常用O型和V型球阀；对于腐蚀性强的易结晶的流体常用阀体分离型的阀体。

The Transmitter module is normally used with the 4-20mA Positioner Board and the board’s power supply. It can also be used as a stand alone feedback transmitter when no position controller is used, but will require an external power supply for stand alone application. This internally mounted module provides a 4-20mA output signal directly proportional to the Positioner Board feedback potentiometer. This signal can be used by a remote instrument to monitor or display actuator position. Zero and span adjustments allow adjustment of the Transmitter’s 4-20mA signal to correspond with the zero and span positions set by the Positioner Board.Friction BrakeAvailable for all Premium Electric actuated valves. Internally mounted device which is used to eliminate mechanical “coast” of the actuator motor at the end of its cycle.

阀门选用标准及要求阀门选型一般要求阀体常用材质阀门内件常用材质阀门密封面常用材料及适用温度闸阀平板闸阀锲式闸阀截止阀柱塞阀球阀节流阀旋塞阀蝶阀止回阀隔膜阀蒸汽疏水阀安全阀减压阀一般要求：根据我集团各产品生产工艺的特点，针对各种介质，作阀门选用的一般要求如下：第一条：阀门选用的第一原则是阀门的密封性能要符合介质的要求。

即内漏要符合标准GB /T13927-1992《通用阀门压力试验》，外漏则是根本不允许的。

第二条：正确选择阀门的类型。

阀门类型的正确选择是以选用者对整个生产工艺流程需要的综合估计为先决条件的，在选择阀门类型的同时，选用者应首先了解每种阀门的结构特点和性能。

一般阀门的类型选择如中低压蒸汽选用铜密封面的截止阀，DN200以上的蒸汽用闸阀；循环水总管上用蝶阀，支管上用衬胶闸阀；低压空气总管上用蝶阀，支管上用截止阀；一般液态物料用球阀等。

第三条：确定阀门的端部连接。

在螺纹连接、法兰连接、焊接端部连接中，前两种最常用，其中螺纹连接形式的价格比法兰连接形式低得多，一般为较小口径阀门，应首先选用。

第四条：阀门主要零件材质的选择。

选择阀门主要零件的材质，首先应考虑到工作介质的物理性能（温度、压力）和化学性能（腐蚀性）等。

同时还应了解介质的清洁程度（有无固体颗粒）。

除此之外，还要参照国家和使用部门的有关规定的要求。

正确合理地选择阀门的材料可以获得阀门最经济的使用寿命和最佳的性能。

(附表1-1、1-2、1-3) 阀体材料选用顺序大致按照铸铁-碳钢-不锈钢，密封圈材料选用顺序：橡胶-铜-合金钢-F4。

第五条：确定流经阀门的流量。

第六条：压力等级选用按照由低到高顺序。

阀门选型手册-阀门选型的步骤和依据阀门选型手册-阀门选型的步骤和依据在流体管道系统中，阀门是控制元件，其主要作用是隔离设备和管道系统、调节流量、防止回流、调节和排泄压力。

由于管道系统选择最适合的阀门显得非常重要，所以，了解阀门的特性及选择阀门的步骤和依据也变得至关重要起来。

阀门行业到目前为止，已能生产种类齐全的闸阀、截止阀、节流阀、旋塞阀、球阀、电动阀、隔膜阀、止回阀、安全阀、减压阀、蒸汽疏水阀和紧急切断阀等12大类、3000多个型号、4000多个规格的阀门产品；最高工作压力为600MPa，最大公称通径达5350mm，最高工作温度为1200℃，最低工作温度为-196℃，适用介质为水、蒸汽、油品、天然气、强腐蚀性介质（如浓硝酸、中浓度硫酸等）、易燃介质（如笨、乙烯等）、有毒介质（如硫化氢）、易爆介质及带放射性介质（金属钠、-回路纯水等）。

阀门承压件材质铸铜、铸铁、球墨铸铁、高硅铸铁、铸钢、锻钢、高、低合金钢、不锈耐酸钢、哈氏合金、因科镍尔、蒙乃尔合金、双相不锈钢、钛合金等。

并且能够生产各种电动、气动、液动阀门驱动装置。

面对如此众多的阀门品种和如此复杂的各种工况，要选择管道系统最适合安装的阀门产品，我以为，首先应了解阀门的特性；其次应掌握选择阀门的步骤和依据；再者应遵循选择阀门的原则。

1．阀门的特性一般有两种，使用特性和结构特性。

使用特性：它确定了阀门的主要使用性能和使用范围，属于阀门使用特性的有：阀门的类别（闭路阀门、调节阀门、安全阀门等）；产品类型（闸阀、截止阀、蝶阀、球阀等）；阀门主要零件（阀体、阀盖、阀杆、阀瓣、密封面）的材料；阀门传动方式等。

结构特性：它确定了阀门的安装、维修、保养等方法的一些结构特性，属于结构特性的有：阀门的结构长度和总体高度、与管道的连接形式（法兰连接、螺纹连接、夹箍连接、外螺纹连接、焊接端连接等）；密封面的形式（镶圈、螺纹圈、堆焊、喷焊、阀体本体）；阀杆结构形式（旋转杆、升降杆）等。
