产品介绍
阀杆螺母
阀杆螺母的材料完全符合API标准,可耐高温,抗腐蚀能力强。
螺栓连接
栓接阀杆的制造严格按照API600标准规范。螺母的制造严格按照ANSI B1.1标准规范。
栓接螺母,六角形, 刚性,热锻,制造严格按造标准ANSI B 18.2.2.
阀盖
阀盖和阀体壁厚相同与支架连接或分开.体盖连接法兰的孔口平面能与螺栓螺母完全吻合.
当阀门全开时可以更换填料,阀杆填料函尺寸严格按照API标准执行.
阀杆
单片结构的阀杆表面经过热处理,硬度良好。头部呈圆形且表面经过抛光处理,可降低其与阀板接套之间的摩擦。
阀板
阀板可随阀杆自由转动,当关闭阀门时可减小与阀座之间的摩擦。阀板锻造并经过磨圆,镜面抛光,热处理和硬度调整。
阀体
铸钢阀体的壁厚高于API600的最低标准要求.通口和阀座尺寸按照ANSI B 16.5
的管件标准要求设计。可更换阀座,体盖连接为内外螺纹副,阀体中心为椭圆形可增加中腔壁厚, 承压力能力亦随之增强。
