蒸汽減壓閥介紹Y43H蒸汽減壓閥屬于先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力、利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動(dòng)活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實(shí)現(xiàn)減壓穩(wěn)壓功能。Y43H蒸汽減壓閥主要用于蒸汽管路，起減壓穩(wěn)壓作用。蒸汽減壓閥主要技術(shù)參數(shù)和性能指標(biāo) 閥體 閥蓋 底蓋WCB閥座 閥盤2Cr13缸套2Cr13/25(鍍硬鉻)活塞2Cr13/銅合金活塞環(huán)合金鑄鐵導(dǎo)閥座 導(dǎo)閥桿2Cr13膜片1Cr18Ni9Ti主閥彈簧50CrVA導(dǎo)閥主彈簧50CrVA調(diào)節(jié)彈簧60Si2Mn蒸汽減壓閥流量系數(shù)(Cv)DN1520253240506580100125150200250300350400500Cv12.546.591625366410014025040057078010201500蒸汽減壓閥主要外形連接尺寸(PN1.6-4.0)公稱通徑DN外 形 尺 寸LHHl1.6/2.5MPa4.0MPa15160180295902016018033098251802003301103220022033011040220240345125502502703451256528030035013080310330385160100350380385170125400450400200150450500415210200500550475240250650525290300800580335350850620375400900660405450900730455500950750465蒸汽減壓閥主要外形連接尺寸(PN6.4-16.0) DN外 形 尺 寸LHHl6.4MPa10.0/16.0MPa151801803051052018020034010525200220340120322202303401204024024035513550270300355135653003403601408033036039517100380400185125450415215150500430225200550495260250650545310300800600355350850640395400900690435500950780495Y43H蒸氣減壓閥_圣核閥門制造(上海)有限公司
