2020年10月15日，工業用燃氣表電機閥故障處理方法(fa)氣(qi)(qi)(qi)動(dong)球(qiu)閥(fa)(fa)故障處理方法(fa)氣(qi)(qi)(qi)動(dong)球(qiu)閥(fa)(fa)它以壓縮(suo)空(kong)(kong)氣(qi)(qi)(qi)為(wei)(wei)動(dong)力(li)，球(qiu)桿帶動(dong)球(qiu)體回(hui)轉90度(du)即(ji)可實現(xian)全(quan)開(kai)——全(quan)閉的(de)(de)(de)動(dong)作(zuo)(zuo)。閥(fa)(fa)座形式(shi)：T，F，C型(xing)。其配(pei)套使用的(de)(de)(de)附件(jian)有(you)空(kong)(kong)氣(qi)(qi)(qi)過濾(lv)減(jian)壓閥(fa)(fa)，限位(wei)開(kai)關(guan)，電(dian)磁(ci)閥(fa)(fa)。其中(zhong)空(kong)(kong)氣(qi)(qi)(qi)過濾(lv)減(jian)壓閥(fa)(fa)的(de)(de)(de)主要(yao)作(zuo)(zuo)用是(shi)(shi)：穩(wen)定壓力(li)，過濾(lv)空(kong)(kong)氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)雜質與(yu)水汽。該(gai)閥(fa)(fa)使用一定時間(jian)經(jing)常出現(xian)的(de)(de)(de)故障是(shi)(shi)漏氣(qi)(qi)(qi)。下面簡(jian)單介紹(shao)一下該(gai)閥(fa)(fa)的(de)(de)(de)常見(jian)故障及相應的(de)(de)(de)維修方法(fa)。對于(yu)(yu)氣(qi)(qi)(qi)動(dong)球(qiu)閥(fa)(fa)的(de)(de)(de)漏氣(qi)(qi)(qi)方式(shi)，常見(jian)的(de)(de)(de)有(you)以下幾種：汽缸(gang)(gang)(gang)上的(de)(de)(de)電(dian)磁(ci)閥(fa)(fa)漏氣(qi)(qi)(qi)，可能(neng)是(shi)(shi)由(you)于(yu)(yu)減(jian)壓閥(fa)(fa)中(zhong)的(de)(de)(de)氣(qi)(qi)(qi)壓過高。汽缸(gang)(gang)(gang)的(de)(de)(de)排氣(qi)(qi)(qi)孔漏氣(qi)(qi)(qi)，這是(shi)(shi)因為(wei)(wei)汽缸(gang)(gang)(gang)內部(bu)的(de)(de)(de)兩(liang)個活動(dong)部(bu)件(jian)與(yu)缸(gang)(gang)(gang)體的(de)(de)(de)密(mi)(mi)封處的(de)(de)(de)密(mi)(mi)封圈出現(xian)老化現(xian)象。汽缸(gang)(gang)(gang)的(de)(de)(de)上下部(bu)漏氣(qi)(qi)(qi)，這是(shi)(shi)由(you)于(yu)(yu)執(zhi)行(xing)機(ji)構(gou)與(yu)氣(qi)(qi)(qi)缸(gang)(gang)(gang)的(de)(de)(de)密(mi)(mi)封處的(de)(de)(de)密(mi)(mi)封圈由(you)于(yu)(yu)其執(zhi)行(xing)機(ji)構(gou)的(de)(de)(de)頻繁活動(dong)而沒有(you)達到密(mi)(mi)封的(de)(de)(de)效果(guo)。除上面的(de)(de)(de)3種情(qing)況以外，還有(you)另外一種情(qing)況也(ye)可能(neng)使汽缸(gang)(gang)(gang)漏氣(qi)(qi)(qi)，即(ji)汽缸(gang)(gang)(gang)中(zhong)的(de)(de)(de)彈簧損壞，由(you)于(yu)(yu)力(li)到不(bu)到位(wei)造(zao)(zao)成的(de)(de)(de)，這也(ye)可能(neng)造(zao)(zao)成關(guan)不(bu)到位(wei)。

     對應解決辦法：更換(huan)執(zhi)行機構的(de)密(mi)(mi)封圈(quan)(quan)。更換(huan)汽(qi)缸處(chu)的(de)密(mi)(mi)封圈(quan)(quan)。將減(jian)壓閥的(de)氣壓調(diao)節為(wei)3-5公斤(jin)，或者是將電(dian)(dian)磁閥下(xia)部(bu)處(chu)拆開(kai)(kai)(kai)(kai)通氣動(dong)(dong)作(zuo)幾次，有(you)(you)時(shi)(shi)也有(you)(you)可(ke)(ke)能更換(huan)電(dian)(dian)磁閥。指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)故(gu)(gu)(gu)障(zhang)(zhang)，故(gu)(gu)(gu)障(zhang)(zhang)現(xian)(xian)象：給(gei)電(dian)(dian)動(dong)(dong)執(zhi)行機通電(dian)(dian)后(hou)發(fa)現(xian)(xian)電(dian)(dian)源(yuan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)不(bu)(bu)亮，伺放(fang)板(ban)無反(fan)饋(kui)，給(gei)信(xin)(xin)號(hao)(hao)不(bu)(bu)動(dong)(dong)作(zuo)。故(gu)(gu)(gu)障(zhang)(zhang)判斷和(he)檢(jian)(jian)(jian)(jian)修過程：因(yin)電(dian)(dian)源(yuan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)不(bu)(bu)亮，首(shou)先(xian)檢(jian)(jian)(jian)(jian)查保(bao)(bao)險管是否開(kai)(kai)(kai)(kai)路(lu)，經(jing)檢(jian)(jian)(jian)(jian)查保(bao)(bao)險管完(wan)好，綜合(he)故(gu)(gu)(gu)障(zhang)(zhang)現(xian)(xian)象，可(ke)(ke)以(yi)推斷故(gu)(gu)(gu)障(zhang)(zhang)有(you)(you)可(ke)(ke)能發(fa)生(sheng)在伺放(fang)板(ban)的(de)電(dian)(dian)源(yuan)部(bu)分,接著檢(jian)(jian)(jian)(jian)查電(dian)(dian)源(yuan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)，用萬(wan)用表檢(jian)(jian)(jian)(jian)測(ce)發(fa)現(xian)(xian)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)開(kai)(kai)(kai)(kai)路(lu)，更換(huan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)故(gu)(gu)(gu)障(zhang)(zhang)排除(chu)。結論：電(dian)(dian)源(yuan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)開(kai)(kai)(kai)(kai)路(lu)會造成整個伺放(fang)板(ban)不(bu)(bu)工作(zuo)。故(gu)(gu)(gu)障(zhang)(zhang)現(xian)(xian)象：電(dian)(dian)動(dong)(dong)執(zhi)行器的(de)執(zhi)行機構通電(dian)(dian)后(hou)，給(gei)信(xin)(xin)號(hao)(hao)開(kai)(kai)(kai)(kai)可(ke)(ke)以(yi)，關(guan)不(bu)(bu)動(dong)(dong)作(zuo)。故(gu)(gu)(gu)障(zhang)(zhang)判斷和(he)檢(jian)(jian)(jian)(jian)修過程：先(xian)仔細檢(jian)(jian)(jian)(jian)查反(fan)饋(kui)線(xian)路(lu)，確認反(fan)饋(kui)信(xin)(xin)號(hao)(hao)無故(gu)(gu)(gu)障(zhang)(zhang)，給(gei)開(kai)(kai)(kai)(kai)信(xin)(xin)號(hao)(hao)時(shi)(shi)開(kai)(kai)(kai)(kai)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)亮，說(shuo)明開(kai)(kai)(kai)(kai)正常，給(gei)關(guan)信(xin)(xin)號(hao)(hao)時(shi)(shi)關(guan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)不(bu)(bu)亮，說(shuo)明關(guan)可(ke)(ke)控硅部(bu)分有(you)(you)問(wen)題，首(shou)先(xian)檢(jian)(jian)(jian)(jian)查關(guan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)，用萬(wan)用表檢(jian)(jian)(jian)(jian)測(ce)發(fa)現(xian)(xian)關(guan)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)開(kai)(kai)(kai)(kai)路(lu)，將其更換(huan)后(hou)故(gu)(gu)(gu)障(zhang)(zhang)排除(chu)。結論：關(guan)和(he)開(kai)(kai)(kai)(kai)指(zhi)(zhi)(zhi)(zhi)示(shi)(shi)燈(deng)(deng)(deng)不(bu)(bu)亮(開(kai)(kai)(kai)(kai)路(lu))時(shi)(shi)可(ke)(ke)控硅不(bu)(bu)動(dong)(dong)作(zuo)。
