The following cases, to go with locator: 1, medium pressure high pressure big time; 2, valve diameter is large Forged Gate, Globe, Check Valves (DN 00); 3, high or low temperature control valve; 4, the action necessary to raise the speed control valve; 5, using standard signal, the operation of non-standard spring when the implementing agency (20 ~ 100KPa spring outside the range); 6, when used for sub-process control; 7, when the valve to achieve the reverse action (air to close each open-type gas conversion); 8, need to change the valve's flow characteristic time (you can change the positioner cam); 9, no spring actuator or piston actuator, the proportion of action to achieve the time; 10, electrical signals to operate pneumatic actuator must Distribution - gas valve positioner.

下列情况下，要配定位器： 1、介质压力高、压差大的时候； 2、调节阀口径大时（DN00）； 3、高温或低温调节阀； 4、需要提高调节阀的动作速度时； 5、用标准信号、操作气动管路截止阀非标准弹簧的执行机构时（20～100KPa以外的弹簧范围）； 6、用于分程控制时； 7、使阀门实现反向动作时（气关式和气开式互相转换）； 8、需要改变阀的流量特性时； 9、无弹簧执行机构或活塞执行机构，要实现比例动作时； 10、用电信号去操作气动执行机构时，必须配电-气阀门定位器。

After Huang Qu senior official yellow Jinlong looking pensive stopping, also in a low voice saying:"Knows, on the Earth 60,000,000 year ago dinosaur exterminate, it is said is because at that time a diameter reached 200 kilometers planetoids to hit Saturn high speed, caused the Saturn entire stratum and the earth's crust receives the undulation, and caused the fierce reverse volcanic eruption, finally acted according to the near several centuries the continually exploration research to indicate, Saturn periphery several satellites, and even the giant beautiful saturn's ring, possibly all was creates by this direct hit, moreover most surprising was, spouted the Saturn parent substance together after the burning hot Saturn lava material coagulation, formed the diameter reached 30 kilometer hit fragment, after is hit unexpectedly Saturn fierceSways the movement, flung the Saturn orbit rapidly ......"

黄区长官黄金龙若有所思的停了停之后，又低声的说道：&知道吗，地球上6000万年前的恐龙灭绝，据说就是由于当时一颗直径达200千米的小行星高速撞击土星，导致土星整个地层和地壳受到波动，并引起剧烈的反向火山喷发，结果根据近几个世纪的持续探索研究表明，土星外围的几个卫星，乃至巨大美丽的土星光环，可能都是由这次直接撞击造成的，而且最令人惊讶的是，一块喷出土星母体由炙热的土星熔岩物质凝固后，形成的直径达30公里的撞击碎块，竟被撞击后土星剧烈的摇晃运行，急速甩出了土星轨道……&

Fault propagate model to obtain and combine present prevailing large amount of information, neuron network,etc. method most model, Direct against fuzzy Petri network give and publish undering the jurisdiction of degrees of algorithm of function concrete their; Petri network reasoning method combine trouble tree forward reasoning reverse algorithm of reasoning mainly, The concrete instance of connection is analysed and compares; Participate in potato cake production line background that design with author finally , combine on-the-spot characteristic of equipment, Set up one fault diagnose concrete model of expert system.
