(2)當(dāng)要求的開(kāi)啟壓力超過(guò)彈簧整定壓力范圍,需更換另一根由本公司提供的整定壓力范圍合適的彈簧然后進(jìn)行調(diào)整。
(3)調(diào)整開(kāi)啟壓力時(shí),當(dāng)進(jìn)口介質(zhì)壓力達(dá)到開(kāi)啟壓力的90%以上時(shí),不應(yīng)旋轉(zhuǎn)調(diào)節(jié)螺桿,以免閥瓣跟著旋轉(zhuǎn),損傷密封面
(4)當(dāng)排放壓力或回座壓力不符合要求時(shí),可利用調(diào)節(jié)圈進(jìn)行調(diào)整,調(diào)整方法可參見(jiàn)我公司產(chǎn)品使用說(shuō)明書,調(diào)整后請(qǐng)將鎖緊螺釘擰緊。
(5)A47H、A47Y型雙聯(lián)彈簧式安全閥調(diào)整完畢后,應(yīng)進(jìn)行鉛封。
(6)A47H、A47Y型雙聯(lián)彈簧式安全閥必須垂直安裝,并且最好直接安裝在容器或管道的接頭的頂部而不另設(shè)進(jìn)口管。進(jìn)口管內(nèi)徑應(yīng)不小于安全閥的進(jìn)口通徑。
(7)A47H、A47Y型雙聯(lián)彈簧式安全閥推薦單獨(dú)使用一根排放管,排放管應(yīng)盡可能加以彈性支撐。排放管的內(nèi)徑不應(yīng)小于安全閥的出口通徑,排放管的阻力應(yīng)盡量小。調(diào)整、安裝
