由于冬季溫度比較低，一些設施在沒有防凍保溫的情況下會出現凍堵的現象，例如輸油站里面的油罐排污閥，所以為了保證油罐排污閥可以正常使用，需要對其進行防凍保溫，那么油罐排污閥使用電伴熱系統如何選擇產品型號呢？

  電(dian)(dian)伴(ban)熱(re)系統在(zai)油(you)罐(guan)(guan)附屬(shu)排污(wu)閥的(de)(de)應用(yong)介紹，油(you)罐(guan)(guan)所處(chu)的(de)(de)區域(yu)環境比(bi)較復(fu)雜，所以(yi)為其排污(wu)閥選(xuan)(xuan)擇(ze)電(dian)(dian)伴(ban)熱(re)帶(dai)保溫需要具有(you)(you)防爆(bao)防腐(fu)的(de)(de)功(gong)(gong)能，同時它(ta)的(de)(de)維(wei)持溫度要求又比(bi)較高，因此要選(xuan)(xuan)擇(ze)恒(heng)功(gong)(gong)率電(dian)(dian)伴(ban)熱(re)帶(dai)。恒(heng)功(gong)(gong)率電(dian)(dian)伴(ban)熱(re)帶(dai)具有(you)(you)防爆(bao)防腐(fu)功(gong)(gong)能，維(wei)持和耐溫溫度比(bi)較高，發熱(re)也比(bi)較均勻，它(ta)的(de)(de)金屬(shu)編(bian)織層還可以(yi)起到接地保護的(de)(de)作用(yong)。

  電(dian)(dian)(dian)(dian)伴(ban)(ban)熱系統(tong)在(zai)油罐(guan)附(fu)屬排(pai)污(wu)閥的應(ying)用介紹(shao)，使(shi)(shi)用恒(heng)功率電(dian)(dian)(dian)(dian)伴(ban)(ban)熱帶(dai)為(wei)(wei)油罐(guan)排(pai)污(wu)閥保(bao)溫(wen)(wen)時，可以(yi)纏繞安(an)裝，但不可重疊(die)安(an)裝，因為(wei)(wei)重疊(die)安(an)裝會導致(zhi)溫(wen)(wen)度過熱，同(tong)時要(yao)配合(he)(he)溫(wen)(wen)度控(kong)制(zhi)(zhi)器使(shi)(shi)用，來調節(jie)和控(kong)制(zhi)(zhi)溫(wen)(wen)度。由于恒(heng)功率電(dian)(dian)(dian)(dian)伴(ban)(ban)熱帶(dai)分(fen)為(wei)(wei)并(bing)聯(lian)和串聯(lian)兩(liang)種型號，所(suo)以(yi)需要(yao)進(jin)行型號選(xuan)擇，在(zai)油罐(guan)排(pai)污(wu)閥上使(shi)(shi)用可以(yi)選(xuan)擇并(bing)聯(lian)恒(heng)功率電(dian)(dian)(dian)(dian)伴(ban)(ban)熱帶(dai)產品(pin)，它(ta)適合(he)(he)環(huan)境比(bi)較復(fu)雜(za)、溫(wen)(wen)度要(yao)求較高，大(da)型的管道(dao)(dao)、罐(guan)體設備保(bao)溫(wen)(wen)，而在(zai)長距(ju)離大(da)口(kou)徑的管道(dao)(dao)上保(bao)溫(wen)(wen)串聯(lian)恒(heng)功率電(dian)(dian)(dian)(dian)伴(ban)(ban)熱帶(dai)是比(bi)較合(he)(he)適的產品(pin)。
