薩姆森(sen)SAMSON氣動(dong)控制閥(fa)(fa)工作(zuo)原理(li)流(liu)(liu)(liu)體按箭頭指向,以流(liu)(liu)(liu)開方向流(liu)(liu)(liu)經閥(fa)(fa)門。閥(fa)(fa)芯(xin)的(de)(de)位(wei)置決定(ding)了(le)閥(fa)(fa)芯(xin)與閥(fa)(fa)座(zuo)之間流(liu)(liu)(liu)量(liang)的(de)(de)流(liu)(liu)(liu)通(tong)截面(mian)積。閥(fa)(fa)桿(gan)設計(ji)為連接到支架連接執行(xing)器(qi)的(de)(de)推桿(gan)設計(ji),閥(fa)(fa)桿(gan)密封(feng)為EPDM或(huo)FPM。通(tong)過改變作(zuo)用在執行(xing)機構上的(de)(de)控制信(xin)號(hao)(hao)使閥(fa)(fa)芯(xin)移動(dong)。對于3374型電動(dong)執行(xing)機構及3274型電液執行(xing)機構,該信(xin)號(hao)(hao)是(shi)三階躍信(xin)號(hao)(hao)。如果(guo)附加使用電動(dong)定(ding)位(wei)器(qi),則信(xin)號(hao)(hao)將是(shi)4至20mA或(huo)0至10 V的(de)(de)連續信(xin)號(hao)(hao)。
閥(fa)門(men)定(ding)(ding)(ding)位(wei)(wei)器(qi)作(zuo)為氣(qi)(qi)(qi)動控(kong)制(zhi)閥(fa)的(de)重要(yao)附件,接受控(kong)制(zhi)系統或(huo)控(kong)制(zhi)器(qi)輸出(chu)的(de)電動或(huo)氣(qi)(qi)(qi)動控(kong)制(zhi)信(xin)(xin)號,按預先設置關(guan)系輔助(zhu)氣(qi)(qi)(qi)動執行(xing)器(qi)調整閥(fa)位(wei)(wei)并實現(xian)準(zhun)確定(ding)(ding)(ding)位(wei)(wei)。閥(fa)門(men)定(ding)(ding)(ding)位(wei)(wei)器(qi)將輸入控(kong)制(zhi)信(xin)(xin)號(給定(ding)(ding)(ding)參(can)數(shu)W)和控(kong)制(zhi)閥(fa)位(wei)(wei)反(fan)饋信(xin)(xin)號(被調參(can)數(shu)X)進行(xing)比較、處理,進而(er)輸出(chu)相應的(de)氣(qi)(qi)(qi)動控(kong)制(zhi)信(xin)(xin)號pst(輸出(chu)參(can)數(shu)Y)給氣(qi)(qi)(qi)動執行(xing)器(qi)。
