BURKERT寶德8175型超聲波液位計/寶德超聲波液位計
BURKERT寶德8175型超聲波液位計是一種利用介質(zhì)本身的壓力變化來進行自我調(diào)控，從而保持流經(jīng)該被控系統(tǒng)的流量不變的閥門，具有流量指示，可在線調(diào)節(jié)，適用于供熱及空調(diào)系統(tǒng)等非腐蝕性介質(zhì)。運行前一次性測試調(diào)節(jié)，可使系統(tǒng)流量自動互定在預(yù)設(shè)置的設(shè)定直，該閥門流量調(diào)節(jié)準(zhǔn)確，操作簡單，運行平穩(wěn)，可靠，使用壽命長。BURKERT寶德8175型超聲波液位計工作時（即把此卸荷油道切斷）．油源來油就從該路換向閥進入所控制的執(zhí)行元件，工作壓力大小由圖中壓力閥限定．采用該種卸荷方式是換向閥閥桿從中立位置→工作位置的移動過程中，卸荷油道是逐漸被關(guān)閉的，進入執(zhí)行元件的油量逐漸增加，系統(tǒng)壓力逐漸升高，執(zhí)行元件啟動平穩(wěn)，無沖擊，而且有一定調(diào)速，壓力閥結(jié)構(gòu)簡單．其缺點是卸荷油道長，壓力損失大，尤其換向閥路數(shù)多時，弊端更為突出，該種卸荷方式多用于路數(shù)較少的場合．BURKERT寶德8175型超聲波液位計閥芯的移動，使工作泵的來油進入動臂油缸實現(xiàn)動臂上升。比例導(dǎo)減壓閥的輸出壓力越大，控制主換向閥閥芯的位移越大，主換向閥通過的流量越大，動臂上升的速度越快。當(dāng)操作手柄拉極限位置時，手柄中的限位電磁鐵通電，手柄在極限位置被吸合。動臂以zui大的速度上升，當(dāng)升動臂上位限位開關(guān)所限定的位置時，操作手柄限位電磁鐵斷電，手柄自動恢復(fù)到中位，動臂就可保持在所限定的位置。
