Y43H-64C,Y43H-100C高壓蒸汽減壓閥
Y43H/Y型先導(dǎo)活塞式蒸汽減壓閥
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蒸汽減壓閥主要性能:
本蒸汽減壓閥適用于蒸汽介質(zhì)的管路上,通過調(diào)節(jié)使介質(zhì)壓力降低到目標(biāo)值,當(dāng)進(jìn)口壓力發(fā)生變化時(shí),靠介質(zhì)本身能量自動(dòng)保持出口壓力在一定范圍,但進(jìn)出口的壓差必須≥0.2MPa.詳細(xì)數(shù)值參考下列表格數(shù)據(jù):

Y43H蒸汽減壓閥安裝與使用:
⒈安裝減壓閥前必須先對使用管路系統(tǒng)進(jìn)行沖洗清理,防止施工過程中的焊渣、氧化皮等臟物隨介質(zhì)流入閥內(nèi),影響減壓閥正常工作,并在閥前安裝過濾設(shè)備。
⒉減壓閥在安裝時(shí)盡可能的安裝在便于操作和維修的位置,在管路上安裝該減壓閥時(shí)必須水平直立安裝,管路中的介質(zhì)流向應(yīng)和本閥箭頭指向保持*。
⒊使用時(shí)應(yīng)先把旁路管道上的截止閥門打開,排除管路中的冷凝水和汽水混合物,防止在減壓閥開啟時(shí)產(chǎn)生水擊現(xiàn)象損壞減壓閥,在無異?,F(xiàn)象后,按順時(shí)針方向緩慢旋動(dòng)調(diào)節(jié)螺釘,將出口壓力值調(diào)節(jié)到目標(biāo)壓力,調(diào)節(jié)完成后將調(diào)節(jié)螺釘上的鎖緊螺母背緊,擰上防護(hù)蓋。
⒋安裝減壓閥閥前閥后的直管長度閥前約600MM,閥后約1000MM。
⒌減壓存放應(yīng)在干燥環(huán)境,進(jìn)出口必須用盲板堵塞,*存放還應(yīng)定期進(jìn)行檢查,各部位及加工面上涂上防銹劑。
Y43H蒸汽減壓閥故障與消除方法:
故障現(xiàn)象 | 產(chǎn)生原因 | 消除方法 |
不減壓 | ⒈主閥或附閥密封面有污垢 | ⒈將污垢清除干凈 |
不通汽 | ⒈清洗過程中閥蓋裝錯(cuò)位 | ⒈拆下閥蓋準(zhǔn)確定位后裝好 |
