一：蒸汽安全閥消聲器(qi)用途及產品特點：
安(an)(an)全閥(fa)排(pai)汽消聲器(qi)主要用于電力、化工、冶金等行業中各類泄(xie)(xie)壓(ya)安(an)(an)全閥(fa)、PCV安(an)(an)全閥(fa)和ERV泄(xie)(xie)放排(pai)汽閥(fa)的(de)高(gao)溫高(gao)壓(ya)排(pai)放蒸汽的(de)有效消聲。
蒸汽(qi)(qi)安(an)(an)(an)(an)全閥排(pai)汽(qi)(qi)消聲(sheng)(sheng)(sheng)(sheng)(sheng)器是以針對中(zhong)高頻(pin)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)為主，且消減(jian)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)同時不能(neng)影響安(an)(an)(an)(an)全閥的(de)(de)(de)起跳(tiao)和回座，所以TA系列安(an)(an)(an)(an)全閥排(pai)汽(qi)(qi)消聲(sheng)(sheng)(sheng)(sheng)(sheng)器我們采用了(le)通孔(kong)(kong)(kong)(kong)(kong)擴(kuo)容(rong)(rong)降(jiang)(jiang)壓結合阻(zu)(zu)聲(sheng)(sheng)(sheng)(sheng)(sheng)吸(xi)音的(de)(de)(de)消聲(sheng)(sheng)(sheng)(sheng)(sheng)原理，其中(zhong)以通孔(kong)(kong)(kong)(kong)(kong)擴(kuo)容(rong)(rong)降(jiang)(jiang)壓代替小(xiao)孔(kong)(kong)(kong)(kong)(kong)噴(pen)(pen)注，在結構上(shang)確(que)保安(an)(an)(an)(an)全閥排(pai)汽(qi)(qi)時順暢(chang)，復合式阻(zu)(zu)聲(sheng)(sheng)(sheng)(sheng)(sheng)吸(xi)音罩及阻(zu)(zu)聲(sheng)(sheng)(sheng)(sheng)(sheng)吸(xi)音片的(de)(de)(de)結構能(neng)夠有(you)效地吸(xi)收剩余中(zhong)高頻(pin)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)；PA系列安(an)(an)(an)(an)全閥排(pai)汽(qi)(qi)消聲(sheng)(sheng)(sheng)(sheng)(sheng)器采用了(le)由通孔(kong)(kong)(kong)(kong)(kong)擴(kuo)容(rong)(rong)降(jiang)(jiang)壓管及小(xiao)孔(kong)(kong)(kong)(kong)(kong)噴(pen)(pen)射放(fang)散殼體構成。擴(kuo)容(rong)(rong)降(jiang)(jiang)壓管將汽(qi)(qi)流分注，經此(ci)噪(zao)音衰減(jian)并減(jian)少聲(sheng)(sheng)(sheng)(sheng)(sheng)音的(de)(de)(de)再次產生。小(xiao)孔(kong)(kong)(kong)(kong)(kong)噴(pen)(pen)射放(fang)散殼體是用不銹鋼(gang)加(jia)工鉆(zhan)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)(de)具有(you)眾多小(xiao)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)(de)小(xiao)孔(kong)(kong)(kong)(kong)(kong)元件，把具有(you)寬(kuan)頻(pin)帶的(de)(de)(de)排(pai)汽(qi)(qi)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)推向人耳不敏感的(de)(de)(de)超高頻(pin)區域，并加(jia)速聲(sheng)(sheng)(sheng)(sheng)(sheng)音的(de)(de)(de)衰減(jian)。東勱電力設備安(an)(an)(an)(an)全閥排(pai)汽(qi)(qi)消聲(sheng)(sheng)(sheng)(sheng)(sheng)器具有(you)以下(xia)優點：
1、消聲(sheng)器的消聲(sheng)量能滿足《工業(ye)企業(ye)噪聲(sheng)衛生(sheng)標準(zhun)》的要求，使出口噪聲(sheng)降低36-39分貝(bei)（A聲(sheng)級）；
2、消聲同(tong)時(shi)不(bu)影響(xiang)安全閥的(de)(de)流(liu)量，不(bu)影響(xiang)安全閥的(de)(de)起跳和回座。
3、消聲器(qi)的(de)結構性(xing)能適應瞬間(jian)排放高溫(wen)、高壓蒸(zheng)汽的(de)沖擊。
二、蒸汽(qi)安(an)全閥排汽(qi)消聲器原理(li)：
東勱(mai)電力(li)設備TA系(xi)列蒸(zheng)汽安全(quan)閥排(pai)(pai)汽消音器采用了(le)抗、噴、阻(zu)的消聲(sheng)原(yuan)理(li)，其中以大孔擴容降(jiang)壓(ya)代替(ti)微孔穿板型，在結構上首先保(bao)證(zheng)安全(quan)門排(pai)(pai)汽必須順暢的原(yuan)理(li)，多層次穿孔吸聲(sheng)，并(bing)結合了(le)阻(zu)性消聲(sheng)原(yuan)理(li)，讓蒸(zheng)汽聲(sheng)波進入多孔吸聲(sheng)材(cai)料中的無(wu)數(shu)小孔內，激發多孔材(cai)料分子震動，使聲(sheng)能(neng)為了(le)克服摩(mo)擦阻(zu)力(li)和粘滯力(li)而變(bian)成熱(re)能(neng)，即達(da)到了(le)理(li)想的消聲(sheng)效(xiao)果(guo)，更(geng)保(bao)證(zheng)了(le)蒸(zheng)汽順利排(pai)(pai)放。
三、安全閥排汽消聲器(qi)安裝(zhuang)須知：
（1）安全閥排汽消聲(sheng)器應垂(chui)直于爐(lu)(lu)頂安裝，如圖所(suo)示，用型鋼支架將消聲(sheng)器固(gu)定支座或落地支腿與爐(lu)(lu)頂相(xiang)固(gu)定。
（2）為(wei)增加(jia)爐頂高(gao)空的(de)(de)抗風能力，對(dui)于體形較大消(xiao)聲(sheng)器應(ying)采(cai)用支承式，及在消(xiao)聲(sheng)器前的(de)(de)排汽管裝(zhuang)一段(duan)膨脹(zhang)彎管以(yi)吸(xi)收(shou)熱(re)脹(zhang)。
（3）安(an)全閥排汽(qi)消聲器(qi)下(xia)部的排水口應暢通接(jie)到(dao)地溝，不應裝(zhuang)配閥門。
（4）安全(quan)閥排汽消聲器(qi)裝在(zai)(zai)爐頂平臺(tai)，對(dui)于TA系列(lie)(lie)抗噴阻消聲器(qi)及(ji)FHX系列(lie)(lie)復合(he)式消聲器(qi)排汽出口在(zai)(zai)頂部，應(ying)用(yong)薄板(不銹鋼板、鍍鋅鋼板)制(zhi)作防雨罩一只(zhi)及(ji)周邊加裝防護(hu)網(wang)罩。
（5）安全閥或排汽閥與消聲器這間的(de)排汽管道(dao)上(shang)應沒有疏水點。
（6）對于PA系(xi)(xi)列小(xiao)孔(kong)消聲(sheng)器(qi)(qi)，安裝(zhuang)前(qian)應(ying)(ying)以防小(xiao)孔(kong)堵(du)塞，如新裝(zhuang)的(de)鍋爐或恢復性檢修，投(tou)入運行前(qian)應(ying)(ying)先安裝(zhuang)吹(chui)管(guan)集粒器(qi)(qi)，沖(chong)管(guan)消聲(sheng)器(qi)(qi)對管(guan)路系(xi)(xi)統進行吹(chui)管(guan)，清(qing)除管(guan)道內的(de)雜物。
（7）原則上一只安全門配一只消聲器。對雙(shuang)座式安全門應在安裝(zhuang)時將排(pai)汽管合并成(cheng)一根(gen)排(pai)汽管與消聲器連通
