A41Y不銹鋼安全閥產品用途
不銹鋼安全閥A41Y整體材質選用優質不銹鋼鑄造而成，采用全封閉閥蓋和閥帽結構，安全閥開啟排放時，介質不會向外界泄漏，而全部通過排泄管排掉，又可防止灰塵等雜質進入閥內，適用于溫度不高于200°C的腐蝕性氣體和需要大排量的液體介質。上海申弘閥門有限公司是國內生產安全閥的主導廠，廠內建有遠東*的安全閥測試中心，國產*臺安全閥就是我廠誕生的，二十多年來，申弘牌安全閥的品種已發展到百余個系列，千余個規格，產品廣泛應用于鍋爐、石化、電站以及國防工業。并為國內*座核電站秦山核電站研制成功了*批核級安全閥。
安全閥是受壓設備、容器或管路上的*超壓保護裝置。當設備壓力升高達到預定值時，安全閥自動開啟，繼而全量排放，防止設備壓力繼續升高；當壓力降低到規定值時，安全閥及時自動關閉。申弘牌安全閥是選用者為保護工程設備安全運行的的，zui科學的明智選擇。所謂安全閥廣義上講包括泄放閥，從管理規則上看，直接安裝在蒸汽鍋爐或一類壓力容器上，其必要條件是必須得到技術監督部門認可的閥門，狹義上稱之為安全閥，其他一般稱之為泄放閥。安全閥與泄放閥在結構和性能上很相似，二者都是在超過開啟壓力時自動排放內部的介質，以保證生產裝置的安全。由干存在這種本質上類似性，人們在使用時，往往將二者混同，另外，有些生產裝置在規則上也規定選用哪種均可。因此，二者的不同之處往往被忽視。從而也就出現了許多間題。如果要將二者作出比較明確的定義，則可按照《ASME鍋爐及壓力容器規范》*篇中所闡述的定義來理解：

A41Y不銹鋼安全閥各種工況下使用壽命安全閥比較合理：
（l）熱水鍋爐一般用不封閉帶扳手微啟式安全閥。
（2）蒸汽鍋爐或蒸汽管道一般用不封閉帶扳手全啟式安全閥。
（3）水等液體不可壓縮介質一般用封閉微啟式安全閥，或用安全泄放閥。
（4）高壓給水一般用封閉全啟式安全閥，如高壓給水加熱器、換熱器等。
（5）氣體等可壓縮性介質一般用封閉全啟式安全閥，如儲氣罐、氣體管道等。
（6）E級蒸汽鍋爐一般用靜重式安全閥。
（7）大口徑，大排量及高壓系統一般用脈沖式安全閥，如減溫減壓裝置、電站鍋爐等，如圖8所示。
（8）運送液化氣的火車槽車、汽車槽車、貯罐等一般用內裝式安全閥，如圖4所示。
（9）油罐頂部一般用液壓安全閥，需與呼吸閥配合使用。
（10）井下排水或天然氣管道一般用先導式安全閥，如圖6所示。
（11）液化石油氣站罐泵出口的液相回流管道上一般用安全回流閥。
（12）負壓或操作過程中可能會產生負壓的系統一般用真空負壓安全閥。
（13）背壓波動較大和有毒易燃的容器或管路系統一般用波紋管安全閥。
