阀门定位器原理与调节第一章气动阀门定位器气动阀门定位器的原理图如下:(气关阀正作用)气动阀门定位器实物图如下:气动阀门定位器是按力平衡原理设计工作的,其工作原理方框见上图所示,它是按力平衡原理设计和工作的。
如图上图所示当通入波纹管的信号压力增加时,使杠杆2绕支点转动,档板靠近喷嘴,喷嘴背压经放大器放大后,送入薄膜执行机构气室,使阀杆向下移动,并带动反馈杆(摆杆)绕支点转动,连接在同一轴上的反馈凸轮(偏心凸轮)也跟着作逆时针方向转动,通过滚轮使杠杆1绕支点转动,并将反馈弹簧拉伸、弹簧对杠杆2的拉力与信号压力作用在波纹管上的力达到力矩平衡时仪表达到平衡状态。
此时,一定的信号压力就与一定的阀门位置相对应。
以上作用方式为正作用,若要改变作用方式,只要将凸轮翻转,A向变成B向等,即可。
所谓正作用定位器,就是信号压力增加,输出压力亦增加;所谓反作用定位器,就是信号压力增加,输出压力则减少。
要改变正反作用,Fisher的阀只需要把里面的调节盘拨到另一侧即可。
一台正作用执行机构只要装上反作用定位器,就能实现反作用执行机构的动作;相反,一台反作用执行机构只要装上反作用定位器,就能实现正作用执行机构的动作。
至于气开阀,由于是在膜盒下面通气,需要将如图中的凸轮反转。
第二章电气阀门定位器由于现在DCS在现场使用越来越多,很多控制器都是使用了中控系统的控制器,所以中控到现场的都是4-20mA的电信号,到现场又需要阀动作的比较快。
虽然阀门定位器由最初的气/气阀门定位器、电/气阀门定位器发展到现在的数字阀门定位器、区域总线阀门定位器,但它们的基本原理和主要功能都没有大的改变。
定位器中基本自控元件介绍--电/气转换器原理随着仪表技术的发展,气动仪表领域已逐步被电动仪表和计算机控制所占领,现在只有在一些特殊的场合还在使用气动仪表,作为仪表中的阀门附件“定位器”也由原来的气动阀门(P/P)定位器逐步由电/气(E/P)阀门定位器所代替。
DVC6200(带4-20ma 反馈反馈,,直行程直行程))操作指导一、 反馈件安装如下图所示,确认无论阀门在全开或全关状态下,校准板上的标准线(黑色塑料板上白线,指示的是定位器阀位传感器位置)在反馈磁条上标注的有效行程范围内(两条白色线之间)。
二、 自动行程校验步骤如下步骤如下::定位器将自动开始行程校验校验完成后必须将定位器投入校验完成后必须将定位器投入““In Service”模式模式。
三、 反馈信号设置1\ 功能激活注意:选择”SEND” 发送后才能完成阀位反馈功能激活。
2\反馈信号正反作用设置:在下面这个菜单的第3项Transmitter of Output 里,可以选择阀门在关闭状态或全开状态下反馈信号为4m A.四、调试按钮:在manual setup 菜单下功能激活:1\功能激活选择send 发送完成接线盒自行程校检按钮设置。
2\按压调试按钮3-10秒钟秒钟,,阀门将自动进行行程校验阀门将自动进行行程校验。
五、 灵敏度灵敏度的的调整如发现阀门有震荡,或阀门动作过慢。
可通过Tuning Set(简单理解为灵敏度)的调整进行改善。
点击send 发送。
有 C D E F G H I J K L M 可选,C 阀门反应最慢,M 阀门反应最快,反应越快越容易引起震荡。
六、 Instrument Mode 的设置设置::在进行定位器校验在进行定位器校验、、参数调整时参数调整时,,一般需要将Instrument Mode 置于Out Of Service (或者Not In Service )状态状态,,校验校验、、调整完成后必须投入In Service!。

Partial Stroke Calibration ProgressConfigurationAfter successfully calibrating the valve for PST go to the Detailed Setup FST/ PST tab and verify that the values for the parameters in the Valve Stroke Test group box are correct. Then go to the Partial Stroke group box and enable any of the behaviors required for the PST.Figure 17. Verify FST/PST Values10Once the PST has been setup and calibrated go to the VST Abnormal Criteria group box and select the criteria to be used to evaluate PST after they are run. Then, select the criteria to be used to abort a PST immediately on initiation, and the criteria to be used to prohibit a PST before initiation.Figure 18. Select VST and PST CriteriaCategorize the stroke alerts from the Valve Stroke Alerts tab into one of the Field Diagnostic Alert categories and suppress them if publishing on the segment is not desired.Figure 19. Set Valve Stroke AlertsInitiating a PST DiagnosticIf an Auto PST is desired then go to the Auto PST tab and set up the PST schedule. The instrument will present a message when the next PST becomes due. If a scheduled PST is not initiated then a PST overdue alert is generated. Figure 20. Setting Auto PSTTo run a manual PST select the Partial Stroke Test icon as shown in figure 21.Figure 21. Initiating a Manual PSTFigure 22. Upload or Delete Saved Partial Stroke DiagnosticsBefore the manual PST initiates, you are given theopportunity to upload and save the instrumentdiagnostic data to ValveLink software. Select thedatasets that are Not In Database and upload. Deletion ofthe data from the instrument is not necessary as newdata will overwrite the oldest dataset. Datasets that arenot uploaded to ValveLink software will not be accessiblein the instrument once they are overwritten by new dataFigure 23.

Resulting Press/Tvl Graph Results with Minimum Pause Time DisabledPST travels to Minimum PST Travel + Set Point Overdrive(20% in this case)Figure 29. Resulting Tvl/Time Graph Results with Minimum Pause Time DisabledPST Pause TimeFigure 30. PST Analyzed Data with Minimum Pause Time DisabledSelect a PST style, either with or without Minimize PST Pause Time, and standardize on that style, as the data may be difficult to compare between the two styles. If the desire is to minimize the amount of time the valve is away from the normal end, then enabling Minimize PST Pause Time is recommended. If the amount of time away from the normal end is not a concern, then disabling Minimize PST Pause Time will cause the set point to pause at the end of the outgoing stroke for the travel to catchup to the set point. The results of the test with the Minimize PST Pause Time disabled will be similar to the PST as offered in earlier versions of SIS instruments.Partial Stroke Test InformationValve Stroke TestA valve stroke test is the process of taking the valve from the normal end to another target position at a preconfigured ramp rate before returning to the normal end while gathering data. The data is analyzed to evaluate the condition of the valve assembly against a set of user defined thresholds. A valve stroke test is only run if everything is normal in the instrument. A safety demand signal will always take precedence over a valve stroke test.D Valve Stroke Test, select Partial Stroke Test, Full Stroke Test, or Disable to select the test to run when the test is initiated using the VST_COMMAND parameter.D Partial Stroke Start Point defines the normal end of the valve. The valve needs to be at this end for a PST to be initiated. When a FST is initiated the valve will be moved by the test to this end before being ramped to the opposite end and ramped back. Setting this value to Not Configured will disable partial stroke tests.D Travel Open End defines, in percent (%) of calibrated travel, the point above which the valve is considered to have reached the high end.D Travel Closed End defines, in percent (%) of calibrated travel, the point below which the valve is considered to have reached the low end.D Test Pause Time is the time between the outgoing and incoming strokes of the test. The default value is 5 seconds.Pause Time will not be used if Minimum PST Pause Time is enabled. The outgoing stroke is from the normal end to the PST target and the incoming stroke is the return stroke to normal. See figure 31.D VST High Friction Breakout Pressure indicates that the breakout required a higher force than configured by the user.Refer to figure 31.D VST Low Friction Breakout Pressure indicates that the breakout required a lower force than configured by the user.Refer to figure 31.D Action On a Failed Test defines if the valve should step or ramp back on a failed stroke test.Figure 31.

Target Travel achieved2. Return to the normal endIn addition to the above, any of the following can be selected to evaluate a Partial Stroke Test.1. Breakout Time2. Outgoing Pressure Threshold3. Incoming Pressure Threshold4. High Friction Breakout Pressure5. Low Friction Breakout PressureD VST Abort CriteriaThe PST is terminated and the valve is returned to the normal end. The return to the normal end will be per the user configuration for an aborted test. The abort criteria will only be active if it is added as a criteria to be evaluated during PST by adding it to the PST Abnormal Criteria.The device always aborts a PST if the Max Travel displacement is exceeded.In addition to the above, any of the following can be selected to abort a Partial Stroke Test:1. Breakout Time2. Incoming Pressure Threshold3. High Friction Breakout PressurePartial & Full StrokeD Partial StrokePST Max Travel defines how much travel displacement is allowed before the PST aborts (see figure 32).PST Minimum Travel is the percentage of total span that the valve moves away from its normal operating end of travel towards its tripped end of travel during the test. The default value is 10%.Set Point Overdrive defines the extent of the set point overdrive over the Minimum Travel Movement when the early turn around is enabled. When the early turn around is not enabled it defines the travel target.Freeze Analog / Discrete Feedbac k when enabled, freezes the corresponding feedback during a partial stroke test. Minimum PST Pause Time,when enabled, the incoming stroke is initiated as soon as the travel reaches the minimum travel movement. Refer to figure 32 for a time series representation of this parameter.Randomized PST, when enabled the instrument randomizes the target travel, for each PST.PST Randomization is defined in percent (%) of calibrated travel span, it defines the extent of randomization from the minimum travel movement towards the normal end. If the user defined randomization is too large the instrument will cap the max randomization to ensure that there will be at least 1% travel movement away from the defined normal end. Refer to figure 31.2122Figure 32. Time Series Representation of Minimum PST Pause TimeT R A V E LPAUSE TIMEj MINIMUM TRAVEL MOVEMENT k MAX.

The default value is 0.25%/second.Incoming Ramp Rate is the rate at which the valve will move during the Incoming stroke of the Partial Stroke test. The default value is 0.25%/second.PST Return Lead defines the percent (%) change in setpoint to overcome the hysteresis in the valve assembly. The error between setpoint and actual error is added to this percent change. For example, if the Return Lead is set at 0.5% and there is a 1% error this will be set at 1.5%PST Breakout Timeout is the user configured amount of time before which the valve must leave the normal end during a PST.VST Outgoing Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the outgoing stroke (see figure 31). This prevents the DVC6200f from exhausting (or building) excessive pressure from/to the actuator in an attempt to move a stuck valve. During PST Calibration, the Partial Stroke Outgoing Pressure Threshold will be set automatically.VST Incoming Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the incoming stroke (see figure 31). This prevents the DVC6200f from exhausting (or building) excessive pressure from /to the actuator in an attempt to move a stuck valve.D Full StrokeFull Stroke Ramp Rate is the rate at which the valve will move during the full stroke test.FST Wait Time is the amount of time to wait for the valve to move to the normal end after initiation of the full stroke test.Full Stroke Breakout Timeout is the user configured amount of time before which the valve must leave the normal end during a full stroke test.PST ProhibitedA partial stroke test will not be initiated if any of the following user-configurable conditions are active:1.
