style="text-indent:25px">閥門信號反饋器當設備內(nèi)的壓力多的過規(guī)定的工作壓力并達到閥的開啟壓力時，內(nèi)部介質(zhì)作用于鬧瓣上面的力大于加載機構(gòu)施加在它上面的力，于是閥瓣離開閥座，閥開啟，設備內(nèi)的介質(zhì)即通過閥座排出、如果閥的排量大于設備的泄放量，設備內(nèi)壓力即逐漸下降，而且通過短時間的排氣后，壓力即降回至正常工作壓力。此時內(nèi)壓作用于閥瓣上面的力又小于加載機構(gòu)施加在它上面的力，閥瓣又緊壓著閥座，介質(zhì)停止排出，設備保持正常的工作壓力繼續(xù)運行。所以，閥是通過閥瓣上介質(zhì)作用力與加載機構(gòu)作用力的消長，自行關(guān)閉或開啟以達到防止設備多的壓的目的。</p><p style="text-indent:25px">閥門信號反饋器輸出一個連續(xù)信號；當控制偏差不大（低速區(qū)），信號反饋器輸出脈沖連續(xù)；當控制器偏差很小時（自適應或可調(diào)死區(qū)狀態(tài)），則沒有控制指令輸出。調(diào)試（初始化）在很大程度上是自動進行的。在初始化時，微處理器自動確定執(zhí)行機構(gòu)的零點，比較大的行程，作用方向和執(zhí)行機構(gòu)的定位速度，用這些來確定比較小脈沖時間和死區(qū)，從而使控制達到比較好的效果。使用SIPART PS2信號反饋器上的按鍵和LCD 可以手動操作氣動執(zhí)行機構(gòu)。用于信號反饋器、執(zhí)行機構(gòu)和調(diào)節(jié)閥的監(jiān)控和診斷功能SIPART
