BURKERT氣動(dòng)閥001248中秋節(jié)*
德國寶德BURKERT閥門定位器（又稱：氣動(dòng)閥門定位器）是調(diào)節(jié)閥的主要附件，通常與氣動(dòng)調(diào)節(jié)閥配套使用，它接受調(diào)節(jié)器的輸出信號(hào)，然后以它的輸出信號(hào)去控制氣動(dòng)調(diào)節(jié)閥，當(dāng)調(diào)節(jié)閥動(dòng)作后，閥桿的位移又通過機(jī)械裝置反饋到閥門定位器，閥位狀況通過電信號(hào)傳給上位系統(tǒng)。德國寶德BURKERT閥門定位器是控制閥的主要附件.它將閥桿位移信號(hào)作為輸入的反饋測(cè)量信號(hào),以控制器輸 出信號(hào)作為設(shè)定信號(hào)，進(jìn)行比較，當(dāng)兩者有偏差時(shí)，改變其到執(zhí)行機(jī)構(gòu)的輸出信號(hào)，使執(zhí)行機(jī)構(gòu)動(dòng)作，建立了閥桿位移倍與控制器輸出信號(hào)之間的一一對(duì)應(yīng)關(guān)系。因此，閥門定位器組成以閥桿位移為測(cè)量信號(hào)，以控制器輸出為設(shè)定信號(hào)的反饋控制系統(tǒng)。該控制系統(tǒng)的操縱變量是閥門定位器去執(zhí)行機(jī)構(gòu)的輸出信號(hào)。德國寶德BURKERT閥門定位器的作用（1）用于對(duì)調(diào)節(jié)質(zhì)量要求高的重要調(diào)節(jié)系統(tǒng)，以提高調(diào)節(jié)閥的定位及可靠性。（2）用于閥門兩端壓差大（ △p>1MPa）的場(chǎng)合。通過提高氣源壓力增大執(zhí)行機(jī)構(gòu)的輸出力，以克服液體對(duì)閥芯產(chǎn)生的不平衡力，減小行程誤差。 　　（3）當(dāng)被調(diào)介質(zhì)為高溫、高壓、低溫、有毒、易燃、易爆時(shí)，為了防止對(duì)外泄漏，往往將填料壓得很緊，因此閥桿與填料間的摩擦力較大，此時(shí)用定位器可克服時(shí)滯。
BURKERT 5281型電磁閥：伺服輔助是電磁閥系列：適用于中性氣體和液體及壓縮空氣，廣泛應(yīng)用于過程控制系統(tǒng)，化學(xué)處理，水/污水處理和消毒處理中。
BURKERT 2000型角座閥：外部先導(dǎo)角座閥。溢流口與滑塊間有自調(diào)節(jié)密封壓蓋，閥體角座結(jié)構(gòu)可實(shí)現(xiàn)較大流量，特別是與普通截止閥相比時(shí)。。。。
