PSQ角行(xing)(xing)程執(zhi)行(xing)(xing)機(ji)構主(zhu)(zhu)要是由相互(hu)隔離的(de)電(dian)器控(kong)制(zhi)部分(fen)和齒(chi)(chi)(chi)(chi)輪(lun)傳動部分(fen)組成，電(dian)機(ji)做為連接兩(liang)隔離部分(fen)的(de)中(zhong)間部件。電(dian)機(ji)轉(zhuan)(zhuan)矩通過(guo)主(zhu)(zhu)齒(chi)(chi)(chi)(chi)輪(lun)傳送(song)到行(xing)(xing)星齒(chi)(chi)(chi)(chi)輪(lun)，主(zhu)(zhu)齒(chi)(chi)(chi)(chi)輪(lun)驅(qu)動行(xing)(xing)星齒(chi)(chi)(chi)(chi)輪(lun)帶動中(zhong)空的(de)齒(chi)(chi)(chi)(chi)輪(lun)。中(zhong)空齒(chi)(chi)(chi)(chi)輪(lun)比二級齒(chi)(chi)(chi)(chi)輪(lun)少三個(ge)齒(chi)(chi)(chi)(chi)，因此可(ke)(ke)以由行(xing)(xing)星齒(chi)(chi)(chi)(chi)輪(lun)驅(qu)動，行(xing)(xing)星齒(chi)(chi)(chi)(chi)輪(lun)轉(zhuan)(zhuan)一周中(zhong)空齒(chi)(chi)(chi)(chi)輪(lun)轉(zhuan)(zhuan)動三個(ge)齒(chi)(chi)(chi)(chi)，行(xing)(xing)星齒(chi)(chi)(chi)(chi)輪(lun)的(de)外部始終嚙(nie)合一個(ge)蝸(gua)桿齒(chi)(chi)(chi)(chi)輪(lun)，運行(xing)(xing)時(shi)也(ye)不分(fen)開(kai)(kai)，這種(zhong)設計使電(dian)機(ji)在故障或閥門轉(zhuan)(zhuan)矩意外增加時(shi)可(ke)(ke)直接通過(guo)手(shou)輪(lun)進行(xing)(xing)手(shou)動控(kong)制(zhi)。執(zhi)行(xing)(xing)機(ji)構有(you)兩(liang)個(ge)螺紋(wen)止檔機(ji)構限位(wei)，也(ye)有(you)兩(liang)限位(wei)開(kai)(kai)關(guan)來(lai)(lai)實現電(dian)限位(wei)，每個(ge)轉(zhuan)(zhuan)向的(de)行(xing)(xing)程范(fan)圍可(ke)(ke)以通過(guo)限位(wei)開(kai)(kai)關(guan)的(de)位(wei)置來(lai)(lai)控(kong)制(zhi)，閥門開(kai)(kai)度(du)由一個(ge)凸起的(de)顯示器指示，獨特的(de)轉(zhuan)(zhuan)矩開(kai)(kai)關(guan)可(ke)(ke)調整從50%-100%的(de)***大轉(zhuan)(zhuan)矩，實現轉(zhuan)(zhuan)矩保護(hu)，以防止閥門被卡(ka)死(si)時(shi)造成的(de)閥桿損壞。
