阀门对于工业中很常见，比如石油、化工、核电、冶金、大型煤化工等领域都有很广泛的使用，随着阀门品牌的不断增加，阀门功能的不断进步，阀门领域的不断延展，阀门的标准也显得越来越重要了。陶瓷阀门因为比金属材料结合能力高的特性而被发展使用于工业领域，可以说是阀门史上一次大胆的创新。本文中小编将会从几方面分别为大家介绍各种陶瓷阀门标准以及相关要求。
陶瓷阀门结构材料标准：
1. 陶瓷阀的闸板、阀座密封面材料应采用结构陶瓷制造，具有耐磨损、耐腐蚀和抗高温蠕变、抗热震性等优良性能，以达到长寿命、免维护的特效。
2. 排渣阀阀体下部分应带有排渣口，在关闭的情况下由于管道压力冲向排渣口是渣子彻底排出，不会有灰渣留在阀底，闸板完全密封。
陶瓷阀门设计制造标准：
结构长度标准：GB/T 12221-2005
连接法兰标准：GB/T 9113
压力温度等级：GB/T 12224-2005
试验检验标准：GB/T 13927-2008
陶瓷阀门应用范围标准：
石油化工、冶金、矿山、电力、输煤厂、水泥厂、水处理等行业的灰渣水混合物工况，渣水比>1:6，最大粒度≤50mm。
陶瓷阀门安全标准：
提高阀门产品的安全性，保障设备和人员的安全。许多阀门都是用在压力管道上，安全至关重要。产品质量一定要达到国家标准的要求，壳体的壁厚要求，焊接连接处的探伤检验要求、材料要求等一定要符合国家安全卫生标准。这些要求在《特种设备安全技术规范》被引用，因而成了强制性的要求。
关于陶瓷阀门的标准问题，现在似乎有一点让人捉摸不透。陶瓷阀门是一种新型特种陶瓷阀门，最近几年，在高磨损、高腐蚀工况下广泛使用，现在几乎已经是这些行业的必然选择了。但陶瓷阀门原来并没有专门的标准，其法兰及结构长度等基本上都是按照普通钢制球阀的标准来设计与制造的。就拿国标来说，法兰一般是依照GB/T 9113和JB/T 79.1 来设计制造，结构长度则是依照GB/T 12221-2005(老版本为GB/T 12221-1989)来设计制造的(非标产品除外)。究其原因，应该是因为客户使用陶瓷阀门基本上都是淘汰掉原来的产品后用陶瓷阀门来代替，而相应的管道等配套设备没有改变。
以上就是小编今天对陶瓷阀门标准的全部介绍了，大家是不是觉得清晰明朗了许多呢？陶瓷阀门随着是一项新科技，但是生产和销售它的公司和品牌也非常多，大家在选择的时候一定要仔细，可以通过以上的标准来选择自己心仪的陶瓷阀门，从陶瓷材料的抗压强度、弹性、硬度、韧性等多种方面来选择分析。对陶瓷阀门的标准介绍就说这么多，希望小编今天的讲述能给大家一些参考。
