閥門定位器按其結(jié)構(gòu)形式和工作原理可以分成氣動閥門定位器、電－氣閥門定位器DXP-L21GSEB參數(shù)及設(shè)置
閥門定位器能夠增大調(diào)節(jié)閥的輸出功率，減少調(diào)節(jié)信號的傳遞滯后的情況發(fā)生，加快閥桿的移動速度，能夠提高閥門的線性度，克服閥桿的摩擦力并消除不平衡力的影響，從而保證調(diào)節(jié)閥的正確定位。銷售要經(jīng)驗(yàn)還是要學(xué)歷
一伙劫匪在搶銀行時(shí)說了句至理名言：“通通不許動，錢是國家的，命是自己的！”劫匪回去后，其中一新來的碩士劫匪說，老大，我們趕快數(shù)一下?lián)屃硕嗌?，那老劫匪（小學(xué)文化）說：“你傻啊？這么多，你要數(shù)到什么時(shí)候？今天晚上看新聞不就知道嗎？”
啟示：看來學(xué)歷只是敲門磚啊，經(jīng)驗(yàn)很重要，相信每一個(gè)成功的銷售都有類似的“土方”，類似的“經(jīng)驗(yàn)”啊。
