全自(zi)動無(wu)塔供(gong)水設備閥門止回閥排(pai)氣(qi)閥疏水器

　　全自動無(wu)塔供水(shui)(shui)設備的閥門(men)(men)、止回(hui)閥、排氣(qi)閥和(he)疏水(shui)(shui)器 熱水(shui)(shui)系統中為了方便使用。維(wei)護(hu)檢修，需(xu)設置(zhi)一些控制附(fu)件閥門(men)(men)或(huo)止回(hui)閥。閥門(men)(men)或(huo)止回(hui)閥的種類、型式(shi)在全(quan)自(zi)動無塔供水設備系(xi)統中已有介(jie)紹。熱(re)水(shui)(shui)系(xi)統中在(zai)(zai)選用(yong)時(shi)(shi)應(ying)考(kao)慮(lv)適(shi)用(yong)于介(jie)質溫度的(de)(de)(de)產(chan)品(pin)，同時(shi)(shi)應(ying)考(kao)慮(lv)使用(yong)安裝方便、水(shui)(shui)頭損失小(xiao)(xiao)、節(jie)水(shui)(shui)、性能(neng)可(ke)靠(kao)、防止水(shui)(shui)擊的(de)(de)(de)產(chan)品(pin)，常(chang)選用(yong)蝶閥、球閥等。另外其材質應(ying)與所選用(yong)的(de)(de)(de)管材配合。 水(shui)(shui)在(zai)(zai)加(jia)熱(re)過程中會逸出原溶解(jie)于水(shui)(shui)中的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)和管網(wang)中熱(re)水(shui)(shui)汽化的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)，這些氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)將(jiang)(jiang)引起噪聲、振動(dong)(dong)。應(ying)及時(shi)(shi)加(jia)以排除。在(zai)(zai)上行(xing)下給式(shi)竹網(wang)中常(chang)利(li)用(yong)設(she)置自(zi)(zi)動(dong)(dong)排氣(qi)(qi)(qi)(qi)(qi)閥或氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)液體(ti)(ti)(ti)(ti)(ti)自(zi)(zi)動(dong)(dong)分離(li)器等排除氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)：自(zi)(zi)動(dong)(dong)排氣(qi)(qi)(qi)(qi)(qi)閥的(de)(de)(de)構(gou)造見圖4. I5，自(zi)(zi)動(dong)(dong)排氣(qi)(qi)(qi)(qi)(qi)閥的(de)(de)(de)工(gong)作(zuo)原理，大都是依(yi)靠(kao)水(shui)(shui)對浮(fu)體(ti)(ti)(ti)(ti)(ti)的(de)(de)(de)浮(fu)力，通過杠桿(gan)機構(gou)的(de)(de)(de)傳動(dong)(dong)，使排氣(qi)(qi)(qi)(qi)(qi)孔(kong)自(zi)(zi)動(dong)(dong)啟閉，達到(dao)(dao)自(zi)(zi)動(dong)(dong)阻水(shui)(shui)排氣(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)目(mu)的(de)(de)(de)。當(dang)(dang)閥體(ti)(ti)(ti)(ti)(ti)內無(wu)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)時(shi)(shi)。水(shui)(shui)將(jiang)(jiang)浮(fu)體(ti)(ti)(ti)(ti)(ti)浮(fu)起。通過杠桿(gan)機構(gou)將(jiang)(jiang)排氣(qi)(qi)(qi)(qi)(qi)孔(kong)關閉，而當(dang)(dang)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)從管道進入(ru)閥體(ti)(ti)(ti)(ti)(ti)后(hou)，氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)將(jiang)(jiang)水(shui)(shui)面壓下去。浮(fu)體(ti)(ti)(ti)(ti)(ti)浮(fu)力減小(xiao)(xiao)，浮(fu)體(ti)(ti)(ti)(ti)(ti)依(yi)靠(kao)自(zi)(zi)重下落(luo)，排氣(qi)(qi)(qi)(qi)(qi)孔(kong)開啟，使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)自(zi)(zi)動(dong)(dong)排出。氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)排除后(hou)，水(shui)(shui)又(you)將(jiang)(jiang)浮(fu)體(ti)(ti)(ti)(ti)(ti)浮(fu)起，排氣(qi)(qi)(qi)(qi)(qi)孔(kong)重新關閉，如此連續(xu)運行(xing)，達到(dao)(dao)自(zi)(zi)動(dong)(dong)排氣(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)目(mu)的(de)(de)(de)。
