附 录 C（规范性附录）阀门的无损检验要求C.1 范围本章规定了特殊压力级阀门的铸造、锻造、滚压、轧制和组焊阀体、阀帽、阀盖的无损检验要求及缺陷排除和修复规则。C.2 概述铸造、锻造、滚压、轧制或焊接材料，按材料技术条件要求热处理后检验，至于在机加工前或机加工后进行由制造厂决定。表面应清洁，不能隐蔽不可接受的表面缺陷。检验表面（见C.3.1.2和C.3.2.2）不包括螺纹、钻孔或螺纹孔，如用于螺栓连接、装密封件、阀杆或辅助连接孔的表面。C.3 规定的检查C.3.1 铸件C.3.1.1 射线检查要求作射线检查的阀体、阀帽或阀盖的部位如图C.1至C.11所规定的典型部位，图示A段为要求的拍摄覆盖范围，用tm的倍数表示，tm是由6.1确定的最小壁厚要求值。规定A段长度为3tm或70mm取其较大者。但是，在某些情况下规定的A值会超出图C.1至C.11所示要求的拍摄覆盖面。例如，图C.6的阀体颈部或通道拍摄部位可能容纳不了规定的整个A值。在这种情况下，可通过提供真实的拍摄范围示意图来表示要求。如果规定的整个覆盖宽度A会导致实际拍摄延伸到邻接的边棱和岔口部位，则该A值可以缩小到实际的最大值，覆盖范围作小量变动是允许的。所采用的射线检查程序和验收标准应符合JB/T 6440的规定。C.3.1.1.1 阀体a）在阀体焊接端，从阀体端部往回延伸3tm或70mm中较大值一段距离的环带区。b）在阀体颈部，对自密封阀门从阀体顶部向下延伸，对螺栓连接阀门是从法兰背面向下延伸一个等于3tm或70mm中较大值的一段距离的环带区。c）在阀座和阀体之间的区域内取等于3tm或70mm中较大值宽度，并包含该相接处约210的扇形带区，如图C.1所示。C.3.1.1.2 阀盖填料函与阀盖封板或法兰的相接处，如图C.1所示。C.3.1.1.3 盖板a）带凸台面或不带凸台面的平盖板（见图C.11）不要求作定量检验。b）对于蝶形盖板（见图C.10），在蝶形部分与法兰部分相接区域取宽度等于3tm或70mm中较大值的环带区域。C.3.1.2 表面检验磁粉检验应按JB/T 6439的程序和验收标准、液体渗透检验应按JB/T 6902的程序和验收标准。C.3.1.3 超声波检查超声波检查应按JB/T 6903的程序和验收标准。检验覆盖范围应为图C.1至图C.11所示的典型部位。C.3.2 锻件、棒料、板材和管材产品C.3.2.1 超声波检验和验收按JB/T 6903的规定。射线检查和验收按JB/T 6440 的规定。C.3.2.1.1 阀体通道端部圆筒形部分和阀体颈部。C.3.2.1.2 阀盖填料函和法兰之间的环形部分。C.3.2.1.3 阀瓣a）带凸面的或不带凸面的平盖板（见图C.11）不需作定量检验。b）对于蝶形盖板（见图C.10），在蝶形部分与法兰部分相接附近取宽度等于3tm或70mm中较大值的环带区。如果检验中超声波显示由于晶粒大小的原因无法理解，则该材料应采用C.3.1.1要求的程序作射线检验。厚度小于12.7mm的截面中有超过4.8mm长的线状显示，厚度在12.7mm至25.4mm厚的截面中有超过9.7mm长线状显示，厚度大于25.4mm的截面中有超过19.1mm长的线状显示则定为不合格。C.3.2.2 表面检验阀体、阀盖的所有外表面和可触及的内表面都应进行表面检验。碳钢和合金钢应进行磁粉检验或液体渗透检验；不锈钢应进行液体渗透检验。磁粉检验应按JB/T 6439 的程序和验收标准、液体渗透检验应按JB/T 6902的程序和验收标准。C.3.3 组焊件 由铸件、锻件、棒料、管材、板材坯件混合组焊成的阀体和阀盖应按相应的方法进行检验，对铸件，用C.3.1的方法；对锻件、滚压件或轧制件用C.3.2的方法。所有组焊缝按GB 150.4-2011和3.1.5的规定进行无损检验。图C.1 闸阀阀体(自密封阀盖)图C.2 Y型截止阀阀体(自密封阀盖)注：阀盖与Y型截止阀阀盖相同。图C.3 角阀阀体(自密封阀盖)图C.4 下弯阀体（自密封阀盖）图C.5
