描述:A41Y不锈钢安全阀,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。

A41Y不锈钢安全阀的详细资料:

 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zui佳超压保护装置。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zui理想的,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不锈钢安全阀产品特点

  1. 全启式结构,排量大
  2. 阀瓣处设有反冲盘部件
  3. 平面结构的阀瓣和阀座易于维修和重新加工
  4. 整定压力偏差小,可达±3%
  5. 选用优质的弹簧钢,保证弹簧的寿命和稳定性
