電動調(diào)節(jié)閥使用要點

⑴調(diào)節(jié)閥屬于現(xiàn)場儀表，要求環(huán)境溫度應在-25～60℃范圍，相對濕度≤95%。如果是安裝在露天或高溫場合，應采取防水、降溫措施。在有震源的地方要遠離振源或增加防振措施。

⑵調(diào)節(jié)閥一般應垂直安裝，特殊情況下可以傾斜，如傾斜角度很大或者閥本身自重太大時對閥應增加支承件保護。

⑶安裝調(diào)節(jié)閥的管道一般不要離地面或地板太高，在管道高度大于2 m時應盡量設(shè)置平臺，以利于操作手輪和便于進行維修。

⑷調(diào)節(jié)閥安裝前應對管路進行清洗，排除污物和焊渣。安裝后，為保證不使雜質(zhì)殘留在閥體內(nèi)，還應再次對閥門進行清洗，即通入介質(zhì)時應使所有閥門開啟，以免雜質(zhì)卡住。在使用手輪機構(gòu)后，應恢復到原來的空檔位置。

⑸為了使調(diào)節(jié)閥在發(fā)生故障或維修的情況下使生產(chǎn)過程能繼續(xù)進行，調(diào)節(jié)閥應加旁通管路。

同時還應特別注意，電動調(diào)節(jié)閥的安裝位置是否符合工藝過程的要求。

⑹電動調(diào)節(jié)閥的電氣部分安裝應根據(jù)有關(guān)電氣設(shè)備施工要求進行。如是隔爆型產(chǎn)品應按《爆開危險場所電氣設(shè)備安裝規(guī)范》要求進行安裝。如現(xiàn)場導線采用SBH型或其它六芯或八芯、外徑為??11.3 mm左右的膠皮安裝電纜線。在使用維修中，在易爆場所嚴禁通電開蓋維修和對隔爆面進行撬打。同時在拆裝中不要磕傷或劃傷隔爆面，檢修后要還原成原來的隔爆要求狀態(tài)。

⑺執(zhí)行機構(gòu)的減速器拆修后應注意加油潤滑，低速電機一般不要拆洗加油。裝配后還應檢查閥位與閥位開度指示是否相符。
