style="text-indent:25px">定位器作用：1、用于對調節(jié)質量要求高的重要調節(jié)系統(tǒng),以提高調節(jié)閥的定位精確及可靠性.2、用于閥門兩端壓差大（△p＞1MPa）的場合.通過提高氣源壓力增大執(zhí)行機構的輸出力,以克服流體對閥芯產生的不平衡力,減小行程誤差.3、當被調介質為高溫、高壓、低溫、有毒、易燃、易爆時,為了防止對外泄漏,往往將填料壓得很緊,因此閥桿與填料間的摩擦力較大,此時用定位器可克服時滯.4、被調介質為粘性流體可含有固體懸浮物時,用定位器可以克服介質對閥桿移動的阻力.5、用大口徑（Dg＞100mm）的調節(jié)閥,以增大執(zhí)行機構的輸出推力。</p><p style="text-indent:25px">定位器排出的空氣無法再用只能排大氣，這是定位器的主要耗氣。另外定位器除了智能式的以外，都有一依據(jù)氣動儀表原理工作的部分，其工作動力來自氣源，通過將帶壓氣體減壓所釋放的功來驅動，也要消耗一定氣量?！巴ㄟ^將帶壓氣體減壓所釋放的功來驅動，也要消耗一定氣量。”是指氣動儀表內部工作時用以推動各種膜片、活塞、杠桿運動的各個工作腔室的壓力定位，都是用過有控制的將輸入的壓縮空氣向大氣排放而獲得的。這也是即使在靜止狀態(tài)下，定位器也一直有氣體排出的原因。定位器長期使用后變化小、磨損的燒損小。</p><div

style="text-indent:25px">定位器的作用;1、用于提高輸出力，主要用于高壓差，高壓介質，高溫，低溫和大口徑閥門場合。2、用于提高調節(jié)閥質量和運動速度，主要由于有放大器和足夠的氣源壓力保證。3、用于電—氣轉換，目前多數(shù)調節(jié)閥與計算機相配套，計算機輸出多數(shù)為4—20mA電流信號，可采用電—氣定位器來滿足要求。4、用于分程調節(jié)，兩臺調節(jié)閥分別操作一套設備、一臺調節(jié)閥接收4—12mA電信號，另一臺閥門接收12—20mA電信號。這邊是定位器的一些基本作用了，在實際的應用中這些都是發(fā)揮著關鍵作用的。定位器可以調節(jié)的參數(shù)還有零位彈簧的彈性系數(shù)和反饋杠桿的有效長度。鹽城電氣閥門定位器供應商</p><p style="text-indent:25px">定位器是調節(jié)閥的主要附件。重慶電氣閥門定位器公司</p><p style="text-indent:25px">定位器由于填料的塑性，會產生徑向力，而且會同閥桿之間緊密接觸，但是這種接觸并不是非常均勻的。閥門在使用的過程中，閥桿同填料之間存在著相對運動，隨著高溫、高壓和滲透性強的介質的影響，調節(jié)閥填料函就容易發(fā)生泄漏。一旦出現(xiàn)了泄露，需要采用以下的方法來解決。1.定位器的填料在選用方面，需要選用柔性石墨，因其具有氣密性好，摩擦力小、長期使用后變化小、磨損的燒損小，維修容易等特點。2.填料的各部位以及接觸的各部位需要精加工，保證表面光潔度，減少填料摩擦。重慶電氣閥門定位器公司</p></p><br
