管道(dao)凍堵如(ru)何(he)化(hua)(hua)凍?目前管道(dao)化(hua)(hua)凍有四種方式進行化(hua)(hua)凍,一(yi)是熱(re)水化(hua)(hua)凍法(fa),這(zhe)種方式一(yi)般(ban)只能用于家庭水管凍堵,當取水龍頭(tou)的(de)給水立管被凍結(jie)不能放(fang)水時,先(xian)把(ba)龍頭(tou)卸下來,不要關(guan)來水閘門,用溫度低于80℃熱水(shui)(shui)從立管上往下澆(jiao)淋,立管受熱靠其內壁的(de)冰(bing)開始融(rong)化,再被(bei)有(you)(you)壓力水(shui)(shui)一(yi)頂(ding),冰(bing)柱會從龍頭卸下來的(de)接口處(chu)頂(ding)出來,效(xiao)果較好。此方法,有(you)(you)時用一(yi)壺熱水(shui)(shui)便(bian)能(neng)解決問題(水(shui)(shui)管是否能(neng)夠解凍全拼運(yun)氣)。
二是(shi)為噴燈(deng)解凍法(fa),用噴燈(deng)集中(zhong)烘烤(kao)被凍結水管(guan)(guan)下部,使冰凍逐(zhu)步擴散并形成蒸氣,自下而上使管(guan)(guan)內冰凍熔化。此(ci)種方(fang)法(fa)適用于熱鍍鋅鋼管(guan)(guan)(白(bai)鐵管(guan)(guan)),不適用于塑料管(guan)(guan)(您能在(zai)寒冷(leng)的北(bei)風中(zhong)‘伺候’被凍水管(guan)(guan)多久?存在(zai)明顯的局(ju)限性)。
三是為管道電伴熱帶解凍法,電伴熱帶是由一種高分子PTC材料(liao)制成,通電(dian)(dian)后能(neng)迅(xun)速發熱(re)(re)的伴(ban)熱(re)(re)產品。管道(dao)電(dian)(dian)伴(ban)熱(re)(re)帶(dai)種類很多(duo):有自限(xian)溫電(dian)(dian)伴(ban)熱(re)(re)帶(dai)(或自控溫電(dian)(dian)伴(ban)熱(re)(re)帶(dai))、防(fang)爆電(dian)(dian)伴(ban)熱(re)(re)帶(dai)、太陽能(neng)專用電(dian)(dian)伴(ban)熱(re)(re)帶(dai)等(deng)。將電(dian)(dian)伴(ban)熱(re)(re)帶(dai)纏繞(rao)到管道(dao)上,用絕(jue)熱(re)(re)材料(liao)包裹,可用于管線防(fang)凍、防(fang)結(jie)露(lu)和保溫,現在也有化冰雪系列電(dian)(dian)伴(ban)熱(re)(re)帶(dai)。
四是(shi)為電(dian)熱(re)(re)法熔凍,用(yong)一(yi)臺普通電(dian)焊(han)(han)機把兩根(gen)電(dian)纜用(yong)夾子(zi)(zi)分(fen)別夾在(zai)凍結管(guan)(guan)兩端,把立管(guan)(guan)上龍頭卸下來(lai),接(jie)通電(dian)源(yuan),按不同(tong)管(guan)(guan)徑調整(zheng)電(dian)焊(han)(han)機的(de)(de)電(dian)流量(liang),用(yong)不了很久,冰柱會(hui)從(cong)開(kai)(kai)口(kou)處(chu)躥出。這種(zhong)方法是(shi)利用(yong)水管(guan)(guan)的(de)(de)電(dian)阻很大,接(jie)通電(dian)源(yuan)后(hou),在(zai)管(guan)(guan)身(shen)上將產生熱(re)(re)量(liang),使管(guan)(guan)內壁的(de)(de)冰融化松動(dong)被水壓頂(ding)出。此種(zhong)方法適用(yong)于(yu)絲(si)扣(kou)連接(jie)的(de)(de)熱(re)(re)鍍鋅鋼管(guan)(guan),不適用(yong)于(yu)膠(jiao)圈接(jie)口(kou)的(de)(de)管(guan)(guan)子(zi)(zi)。操作時(shi)應(ying)注意的(de)(de)是(shi),在(zai)借(jie)用(yong)民用(yong)電(dian)源(yuan)時(shi)應(ying)把其它家用(yong)電(dian)器斷開(kai)(kai)電(dian)源(yuan),以免(mian)功率(lv)超載(zai),更應(ying)注意用(yong)電(dian)安全。
