產(chǎn)品概述:
“A47H、A47Y型雙聯(lián)彈簧式安全閥”主要用在受壓設(shè)備、鍋爐、壓力容器或管道上作為起壓保護裝置及安全保護用閥,當(dāng)設(shè)備壓力升高超過允許值,";A47H、A47Y型雙聯(lián)彈簧式安全閥";能自動開啟,繼而全量排放,以防止設(shè)備壓力繼續(xù)升高。當(dāng)壓力降到規(guī)定值時,“A47H、A47Y型雙聯(lián)彈簧式安全閥”能及時關(guān)閉以免壓力過分降低,控制壓力不超過規(guī)定值,自動防止因超壓而可能出現(xiàn)的事故,所以“A47H、A47Y型雙聯(lián)彈簧式安全閥”又被稱為壓力容器的最終保護裝置,在應(yīng)用“A47H、A47Y型雙聯(lián)彈簧式安全閥”時,必須遵循其適用規(guī)范的要求,以確保生產(chǎn)正常進行。

訂貨須知:
一、訂貨須知:
1.A47H、A47Y型雙聯(lián)彈簧式安全閥產(chǎn)品型號與公稱壓力及公稱通徑2.A47H、A47Y型雙聯(lián)彈簧式安全閥連接法蘭標(biāo)準與額定流量系數(shù)Cv3.A47H、A47Y型雙聯(lián)彈簧式安全閥進口壓力與調(diào)節(jié)范圍及工作介質(zhì)和介質(zhì)溫度。
二、安裝及維護應(yīng)注意以下事項:
(1)A47H、A47Y型雙聯(lián)彈簧式安全閥在規(guī)定的整定壓力范圍內(nèi),可以通過旋轉(zhuǎn)調(diào)節(jié)螺桿改變彈簧的壓縮量來對開啟壓力進行調(diào)整。
(2)當(dāng)要求的開啟壓力超過彈簧整定壓力范圍,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行調(diào)整。
(3)調(diào)整開啟壓力時,當(dāng)進口介質(zhì)壓力達到開啟壓力的90%以上時,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,可利用調(diào)節(jié)圈進行調(diào)整,調(diào)整方法可參見我公司產(chǎn)品使用說明書,調(diào)整后請將鎖緊螺釘擰緊。
(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)進口管。進口管內(nèi)徑應(yīng)不小于安全閥的進口通徑。
(7)A47H、A47Y型雙聯(lián)彈簧式安全閥推薦單獨使用一根排放管,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
(8)A47H、A47Y型雙聯(lián)彈簧式安全閥在規(guī)定的整定壓力范圍內(nèi),可以通過旋轉(zhuǎn)調(diào)節(jié)螺桿改變彈簧的壓縮量來對開啟壓力進行調(diào)整。
(9)當(dāng)要求的開啟壓力超過彈簧整定壓力范圍,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行調(diào)整。
(10)調(diào)整開啟壓力時,當(dāng)進口介質(zhì)壓力達到開啟壓力的90%以上時,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
(11)當(dāng)排放壓力或回座壓力不符合要求時,可利用調(diào)節(jié)圈進行調(diào)整,調(diào)整方法可參見我公司產(chǎn)品使用說明書,調(diào)整后請將鎖緊螺釘擰緊。
(12)A47H、A47Y型雙聯(lián)彈簧式安全閥調(diào)整完畢后,應(yīng)進行鉛封。
(13)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)進口管。進口管內(nèi)徑應(yīng)不小于安全閥的進口通徑。
(14)A47H、A47Y型雙聯(lián)彈簧式安全閥推薦單獨使用一根排放管,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
