《阀门培训》课件标题:《阀门培训》课件一、引言阀门是流体输送系统中的重要组成部分,起着控制、调节和切断流体流动的作用。
掌握阀门的原理、结构、类型、安装、调试和维护等知识,对于从事流体输送系统的设计、施工和维护工作的工程师和技术人员来说至关重要。
本课件旨在为阀门培训提供系统的教学内容,帮助学员掌握阀门相关知识,提高实际操作能力。
二、阀门原理与结构1. 阀门原理阀门通过改变阀门通道的截面积,实现对流体流量、压力和流向的控制。
阀门主要由阀体、阀盖、阀杆、阀瓣和密封元件等组成。
阀门的工作原理是利用执行机构(手动、电动、气动等)驱动阀杆,使阀瓣产生相应的位移,从而改变阀门通道的截面积,实现对流体流动的控制。
2. 阀门结构阀门结构主要包括阀体、阀盖、阀杆、阀瓣、密封元件、填料函、填料压盖等部件。
阀体和阀盖是阀门的主体结构,阀杆连接执行机构和阀瓣,阀瓣用于调节流体流量,密封元件和填料函用于实现阀门的密封性能。
三、阀门类型与应用1. 按结构分类(1)截止阀:主要用于切断和接通流体,适用于清洁介质。
(2)闸阀:适用于大口径、高压力的管道,具有流通能力大、阻力小等特点。
(3)球阀:具有结构紧凑、密封性能好、开关迅速等特点,广泛应用于石油、化工等领域。
(4)蝶阀:结构简单、重量轻、操作方便,适用于低压、大口径的管道。
(5)调节阀:用于调节流体流量、压力和温度,具有精确、灵敏的特点。
2. 按驱动方式分类(1)手动阀门:通过手动操作实现开关和控制。
(2)电动阀门:通过电动执行机构实现开关和控制。
(3)气动阀门:通过气动执行机构实现开关和控制。
(4)液动阀门:通过液压执行机构实现开关和控制。
四、阀门安装与调试1. 安装前准备(1)检查阀门型号、规格是否符合设计要求。
(2)检查阀门外观,确保无损坏、变形等缺陷。
(3)检查阀门密封面,确保无划痕、磨损等影响密封性能的问题。
(4)检查阀门连接法兰、螺栓等配件是否齐全、完好。
2. 安装步骤(1)将阀门安装在管道上,确保阀门与管道同轴。

我分公司fisher调阀均为电动调节阀和气动调节阀。
气动调节阀:气动调节阀就是以压缩空气为动力源,以气缸为执行器, 并借助于电/气阀门定位器、转换器、电磁阀、保位阀等附件驱动阀门, (阀芯阀座相对移动)来实现开关量或比例式调节,接收控制信号: 4—20mA电流信号并将电信号转变为压力信号(由定位器完成或电磁 阀完成)来调节管道介质的流量、压力、温度等各种工艺参数。 气动调节阀优点:结构简单、动作可靠稳定、输出力大、安装维修方便、 价格便宜且防火防爆。缺点:响应时间大、信号不适于远传。 电动调节阀:电动执行机构接收4—20mA电流信号,通过电机的正反 转驱使阀芯阀杆产生相对位移(直行程、角行程)来改变阀芯和阀座 之间的截面积大小,控制管道介质的流量、温度、压力等工艺参数。 电动调节阀优点:动作快、适合远距离传送;节能(只在工作时才消耗 电),环保(无碳排放),安装快捷方便(无需复杂的气动管路和气泵 工作站)。 缺点:结构复杂、推力小、价格贵,适用于防爆要求不太高 及缺乏气源的场合。
气动调节阀分类:
按流向不同分为:流开和流关(闭) 流开:在阀芯节流处介质流动方向与阀门打开方向相同。 流关:在阀芯节流处介质流动方向与阀门关闭方向相同。 哪些阀需要进行流向选择, 哪些不需要?单密封类的调节阀: 单阀座、高压阀无平衡孔的单密 封套筒阀需进行流量选择(通常 选择流开)。 流开、流闭各有利弊:流开型阀 门工作比较稳定,但自洁性和密 封性较差,寿命短。流闭型的阀 寿命长、自洁性和密封性好,但 当阀杆直径小于阀芯直径时稳定 性差。 当冲刷严重或有自洁要求时选择 流闭。两位型快关特性调节阀选 择流闭。

调校人员准备:操作员A在上位计算机记录实时数据发布测试指令,操作员B现场调试操作,操作员C作现场记录回复。
调校步骤:插好压力模块与DRUCK TRX-II的信号连接线。
开DRUCK TRX-II 电源,DRUCK TRX-II设置为压力测试量模式。
1.零位调整零位调整的目的是为了保证定位器各部件处于正确的工作位置。
零位调整的过程如下:⑴将执行机构行程调到中间位置,将转臂上的0位对准定位器箱体上的0位刻线,然后使行程销与转臂垂直,全行程值与转臂上刻度对应。
注意:阀杆行程小于1~1/8英寸(29mm)时行程销也必须在1~1/8刻线处。
⑵将喷嘴锁母松开,顺时针拧喷嘴定位器到头,然后反时针拧2周固定。
⑶解除定位器上所有负荷,将定位器的输出,连到执行机构的输入。
⑷将输入信号与定位器相连,首先输入中间值。
比如:3582系列定位器3~15psig(0.2~1.0bar)信号范围时输入9 psig(0.6bar),然后给定位器供气。
注意:正常工作时,挡板必须正对喷嘴,保证挡板不移动,不扭曲。
⑸将挡板打到推板上刻度的零位,输出压力也应为中间值,若不是,松开挡板螺钉,并调整使其输出压力达到中间值然后锁紧。
⑹将挡板转到正作用象限刻度10处,输出压力也应为中间值,若不是,调整波纹管螺栓,使其输出压力达到中间值然后锁紧。
⑺将挡板转到反作用象限刻度10处,输出压力也应为中间值,若不是,调整推板螺栓,使其输出压力达到中间值然后锁紧。
⑻重复⑸、⑹、⑺检查挡板是否正对喷嘴。
若不是,重新调整喷嘴和挡板,直到零位达到。
为行程调整做好准备。
2.行程调整⑴解除负荷,将定位器输出与执行机构输入相连接。
给定位器输入信号并且为中间值。
⑵将挡板调到推板刻度大约为6位置(正作用象限或反作用象限)给定位器供气,执行机构应运动到其行程的中间值。

二.费希尔定位器的工作原理。
三.费希尔定位器的调试及整定。
四.4200反馈快速调整的方法。
费希尔国际有限公司始于1880年,发明人是william Fisher发明了第一台泵调节器。
分类“DVC5000。
DVC6000。
DVC2000DVC2000----------直行程,角行程。
行程:最大2英寸,在大的行程可以通过增加气动放大器,改变双作用。
没有连接杆和连接件减少了安装零件和安装的复杂程度。
里面带非接触式阀位变送器和阀位开关,阀位变送器需要单独供电。
二. 费希尔定位器的工作原理。
Fisher DVC5000/6000系列智能定位器的结构原理图如下图所示智能定位器结构原理图:工作原理:控制器来的控制信号经端子盒进到印刷线路板子模块,在这里被微处理器读取后经数字算法处理后转换成模拟量后送给I/P转换器。
当信号改变时I/P转换器的线圈和衔铁之间的磁吸引力改变,并因此改变了喷嘴挡板间的距离进而改变了喷嘴背压,该背压经放大器放大后送给执行机构并通过执行机构改变阀杆的位置。
阀行程传感器通过反馈杆感受阀杆位置的变化,并将此信号反给印刷线路板组件参与计算。
当阀杆位置达到正确位置,阀杆位置信号反到印刷线路板组建,经过处理后使I/P驱动信号稳定下来,则喷嘴背压稳定下来,则到执行机构的输出力也稳定下来阀杆位置不再变化。
单作用执行机构:将单作用正作用式数字式阀门控制器(a型气动放大器)连接到单作用执行机构上时,必须把输出口B堵死,把输出口A连接到执行机构膜盖上。
在输出口B处不需要压力表,在其相应位置上改装一个带过滤网的排空管塞。
将单作用反作用式数字式阀门控制器(B型气动放大器)连接到单作用执行机构上时,必须把输出口A堵死,把输出口B连接到执行机构膜盖上。
在输出口A处不需要压力表,应改装一个堵头。
双作用执行机构:当用在双作用执行机构上时,DVC6000系列数字式阀门控制器通常采用A型气动放大器,当无输入信号时,如果气动放大器已经调整好,则输出口A的压力应为0,而输出口B的压力等于输入气源的的压力。

Fisher ™ 9500 Butterfly Control ValveThe Fisher 9500 butterfly valve is a fully lined valve for use with corrosive fluids and where tight shutoff is required. The nitrile or PTFE liner totally isolates the valve body and shaft from the process fluid andmaintains excellent shutoff at pressure drops to 15.2bar (220 psi), and temperatures to 121°C (250°F).W9224‐3Fisher 9500 Valve with 1052 Actuator and FIELDVUE ™DVC6200 Digital Valve ControllerThe 9500 valve is available in NPS 2 through 12 and is compatible with ASME B16.1 CL125B, with ASME B16.34 CL150 and CL300, or with DIN flanges. These valves are furnished with splined shafts for use with power actuators, with a Fisher 1077 manual actuator,or with a 1078 declutchable manual actuator (see figure 1).W4082-1Fisher 9500 Valve with 1066SR Actuator231. The pressure/temperature limits in this bulletin and any other applicable standard or code limitation should not be exceeded.2.

Fisher 1077 and 1078 Manual Rotary ActuatorsW4867W45791077 MANUAL ACTUATOR1078 DECLUTCHABLE MANUAL ACTUATOR4Featuresn Versatile—Conventional disks are available forbidirectional, on/off or throttling control. Valves are available with S31600 [316 stainless steel (SST)]FISHTAIL disk for on/off or throttling control (see figure 2). The disks can be obtained in a variety of alloy materials for additional corrosion resistance.n Economical—Valve body and shafts are isolatedfrom process fluid, allowing use of cast iron valve bodies for corrosive applications.n Adjustable Shaft Seal—Liner is directed against a flatdisk hub by a thrust bearing, creating a sealbetween the liner and the disk as shown in figure 3.Seals are adjusted as necessary to provide leak control.n Flange Gasket Not Required—Partial O -ring (figure3) is molded as part of the liner. It seals againstmating flanges which eliminate the need for flange gaskets.n Excellent Flow Control—The conventional disk isapproximately equal percentage flow characteristic through 60 degrees of its rotation. The FISHTAIL disk has an approximate equal percentage flow characteristic through a full 90 degrees of disk rotation.n Operational Economy—The FISHTAIL disk reducesdynamic torque, which allows the use of a smaller actuator size for a given application.n Minimum Maintenance—No lubrication is required,and no packing or flange gaskets to replace. Shaft seal is easy to adjust. Removing valve components and changing the valve action is accomplished without complete disassembly. Field -replaceable slip -in liner minimizes downtime and reduces maintenance costs.5Table 3.

Forconventional disks, flow may be in either direction. For FISHTAIL disks, the FISHTAIL edge of the disks must be located in to the downstream end of the valve (see figure 2).The liner overlaps the valve face producing the partial O -ring shown in figure 3. It acts as the flange gasket.Improper use of additional gasketing materials may damage the valve liner.The simplicity of the 9500 valve design is achieved by relying on mating pipe flanges to retain the slip -in linerin the valve body. Care must be taken duringinstallation to assure that the pipe flanges are properly supported to avoid liner damage, flange joint leakage,and problems with valve operation. Flexible, plastic flanges; fiberglass, slip -on flanges; or weld -neckflanges with other than standard inside diameters may not provide adequate support for the liner. The use of flange adapters can overcome flange support problems during installation. Whenever a flange adapter is used, a standard flange gasket must be installed between the line flange and flange adapter.Do not use a flange gasket between the valve and flange adapter. The partial O -ring on the liner acts as the flange gasket and any additional gasket here will damage the liner.Excessive line bolt load on flexible mating flanges can warp the liner. Also, failing to support the liner at the inside diameter can warp the liner. The use of flange adapters can overcome bolt load problems during installation.Slip -on pipe flanges may be used with NPS 2, 3, or 49500 valves. Valves NPS 6 and larger will require flange adapters for complete liner support.The maximum and minimum allowable insidediameter of mating flanges or adjacent pipes are given in figure 4 and table 5. Flanges or pipes with inside diameters smaller than the minimum shown mayinterfere with the opening of the disk. Flanges or pipes with an inside diameter larger than the maximum shown may not be in full contact with the liner. Flange adapters are needed in either case, to provide disk clearance or to fully contact the liner.7Figure 4.

2.2阀体耐压强度试验此工作要求委托具备阀体耐压强度试验资质的试验站做强度试验,由校验人员做阀门开关的配合工作。
试验在阀门全开状态下用〔5~10℃〕的干净水进展,要求耐压强度试验压力为公称压力的1.5倍时,所有在工作中承受压力的压腔承压3min,没有可见的泄漏现象。
常用ANSI〔psi〕标准与常用PN〔MPa〕标准的换算:2.3阀门的泄漏量试验要求试验所用介质为5~10℃〔空气或氮气〕或清洁水,试验压力为0.35Mpa。
当阀的允许压差小于0.35Mpa时,应选用设计规定的值。
试验时气开阀的气动信号压力为零,气关阀的信号压力为输入信号上限值加上20Kpa;用量杯量取泄漏的介质量,然后与计算的允许泄漏量进展比拟来判断其泄漏是否合格。
当用气体介质做试验时,用排水取气法收集泄漏的气体量进展比拟。
允许泄漏量计算(依据如下附表1-3)附表1调节阀泄漏量分级注:⑴△P为阀前后压差〔kPa〕;⑵D为阀座直径〔mm〕;⑶对于可压缩流体体积流量,绝对压力为101.325kPa和绝对温度为273K的标准状态下的测量值;⑷A试验程序时,应为0.35MPa,当阀的允许压差小于0.35MPa时,用设计规定的允许压差;⑸B试验程序时,应为阀的最大工作压差。
