style="text-indent:25px">閥門定位器，按結(jié)構(gòu)可分為：氣動閥門定位器、電氣閥門定位器及智能閥門定位器，是調(diào)節(jié)閥的主要附件，通常與氣動調(diào)節(jié)閥配套使用，它接受調(diào)節(jié)器的輸出信號，然后以它的輸出信號去控制氣動調(diào)節(jié)閥，當(dāng)調(diào)節(jié)閥動作后，閥桿的位移又通過機械裝置反饋到閥門定位器，閥位狀況通過電信號傳給上位系統(tǒng)。閥門定位器作為整個調(diào)節(jié)閥中較精密的部件，其故障的發(fā)生率也是較多的，一旦出現(xiàn)故障，就會影響整個系統(tǒng)的運行，所以，對于現(xiàn)場的儀表工作人員來說，多了解一些這方面的知識，是很有必要的！由于定位器安裝過程中調(diào)試不準(zhǔn)或現(xiàn)場振動、溫度變化及調(diào)節(jié)閥閥桿行程改變，反饋桿位置的改變等原因使調(diào)節(jié)閥較小開度和較大開度與控制室的信號不一致。致使閥門定位器輸出的信號不能使調(diào)節(jié)閥全開全關(guān)，造成泄露量大，限量等現(xiàn)象。在對定位器現(xiàn)場調(diào)校中首先應(yīng)保證調(diào)節(jié)閥動作良好，反饋系統(tǒng)安裝牢固動作良好，然后通過標(biāo)準(zhǔn)信號來進(jìn)行調(diào)整。使調(diào)節(jié)閥的行程與控制信號一致。襯氟調(diào)節(jié)閥直銷調(diào)節(jié)閥正常運行后要進(jìn)行維護(hù)和保養(yǎng)。</p><div

①把調(diào)節(jié)閥前后距離較近的、壓力基本穩(wěn)定的兩個設(shè)備作為系統(tǒng)的計算范圍。 ②在較大流量條件下，分別計算系統(tǒng)內(nèi)各項局部阻力(調(diào)節(jié)閥除外)所引起的壓力損失△PF，再求出它們的總和Σ△PF。 ③選擇S值。S值應(yīng)為調(diào)節(jié)閥全開時控制閥上壓差△PV和系統(tǒng)總的壓力損失之比，即S=△PV÷(△PV+Σ△PF)，常選S=0.3-0.5。但某些系統(tǒng)，即使S值小于0.3時仍能滿足控制性能的要求。對于高壓系統(tǒng)，為了降低動力消耗，也可降低到S=0.15。對于氣體介質(zhì)，因為阻力損失較小，調(diào)節(jié)閥上的壓差所占的分量較大，所以一般S值都大于0.5。但在低壓及真空系統(tǒng)中，由于允許壓力損失較小，所以S仍以0.3-0.5為宜。</p><p
