A41Y不锈钢安全阀产品用途
不锈钢安全阀A41Y整体材质选用优质不锈钢铸造而成，采用全封闭阀盖和阀帽结构，安全阀开启排放时，介质不会向外界泄漏，而全部通过排泄管排掉，又可防止灰尘等杂质进入阀内，适用于温度不高于200°C的腐蚀性气体和需要大排量的液体介质。上海申弘阀门有限公司是国内生产安全阀的主导厂，厂内建有远东*的安全阀测试中心，国产*台安全阀就是我厂诞生的，二十多年来，申弘牌安全阀的品种已发展到百余个系列，千余个规格，产品广泛应用于锅炉、石化、电站以及国防工业。并为国内*座核电站秦山核电站研制成功了*批核级安全阀。
安全阀是受压设备、容器或管路上的*超压保护装置。当设备压力升高达到预定值时，安全阀自动开启，继而全量排放，防止设备压力继续升高；当压力降低到规定值时，安全阀及时自动关闭。申弘牌安全阀是选用者为保护工程设备安全运行的的，zui科学的明智选择。所谓安全阀广义上讲包括泄放阀，从管理规则上看，直接安装在蒸汽锅炉或一类压力容器上，其必要条件是必须得到技术监督部门认可的阀门，狭义上称之为安全阀，其他一般称之为泄放阀。安全阀与泄放阀在结构和性能上很相似，二者都是在超过开启压力时自动排放内部的介质，以保证生产装置的安全。由干存在这种本质上类似性，人们在使用时，往往将二者混同，另外，有些生产装置在规则上也规定选用哪种均可。因此，二者的不同之处往往被忽视。从而也就出现了许多间题。如果要将二者作出比较明确的定义，则可按照《ASME锅炉及压力容器规范》*篇中所阐述的定义来理解：

A41Y不锈钢安全阀各种工况下使用寿命安全阀比较合理：
（l）热水锅炉一般用不封闭带扳手微启式安全阀。
（2）蒸汽锅炉或蒸汽管道一般用不封闭带扳手全启式安全阀。
（3）水等液体不可压缩介质一般用封闭微启式安全阀，或用安全泄放阀。
（4）高压给水一般用封闭全启式安全阀，如高压给水加热器、换热器等。
（5）气体等可压缩性介质一般用封闭全启式安全阀，如储气罐、气体管道等。
（6）E级蒸汽锅炉一般用静重式安全阀。
（7）大口径，大排量及高压系统一般用脉冲式安全阀，如减温减压装置、电站锅炉等，如图8所示。
（8）运送液化气的火车槽车、汽车槽车、贮罐等一般用内装式安全阀，如图4所示。
（9）油罐顶部一般用液压安全阀，需与呼吸阀配合使用。
（10）井下排水或天然气管道一般用先导式安全阀，如图6所示。
（11）液化石油气站罐泵出口的液相回流管道上一般用安全回流阀。
（12）负压或操作过程中可能会产生负压的系统一般用真空负压安全阀。
（13）背压波动较大和有毒易燃的容器或管路系统一般用波纹管安全阀。
