Features The double-clip connected ball valve possess such features as compact structure, smaller volume, lighter ponderance, fine sealing performance,flexible on-off, convenient installation course, etc. The heating double-clip connected ball valve enjoys favorable heat/cold preservation performances which not only effectively prevent the slabby medium in pipelines from solidifying but also reduce the heat loss of the medium in pipelines. The double-clip connected ball valve series could also be applied with the mounted corresponding motor or air operated plant to implement remote control or automatic control. 对夹球阀技术规范Technical Specification 结构形式 Structure form | 对夹式 Double-clip type | 连接法兰 Connecting flange | ANSI B16.5、JB/T79 | 驱动方式 Driving manner | 手动、电动、气动 Manual,Moton driving,Pneumatil | 试验和检验 Test & Inspection | JB/T9092-99 API 598 | 主要零件材质表Form of Major Patrs Materials 序号 NO | 零件名称 Accessory name | 材 质 Material | GB | ASTM | 1 | 阀体 Body | CF8 | A351-CF8 | 2 | 密封圈 Sealing Ring | PTFE、PPL | 3 | 球体 Ball | 0Cr18Ni9 | A351-CF8 | 4 | 阀杆 Stem | 0Cr18Ni9 | A276-304 | 5 | 阀座 Seat | 0Cr18Ni9 | A276-304 | 6 | 垫片 Gasket | PTFE、PPL | 7 | 垫片 Gasket | 柔性石墨 不锈钢 Graphite stainless steel | 8 | 填料 Stuffing | PTFE、PPL | 9 | 压套 Stufing cover | 0Cr18Ni9 | A351-CF8 | 主要外型及连接尺寸表Main Types and Connecting Dimension 公称通径(DN) Nominal diameter | 主 要 尺 寸 (mm)Main dimension | L | D | W | H | ( mm) | ( in) | 1.0MPa | 1.6MPa | 2.5MPa | 150Lb | 10k | 手动 | 手动 | 15 | 1/2 | 40 | 53 | 53 | 53 | 47 | 58 | 130 | 80 | 20 | 3/4 | 45 | 63 | 63 | 63 | 57 | 63 | 170 | 80 | 25 | 1 | 50 | 73 | 73 | 73 | 66 | 74 | 170 | 100 | 32 | 11/4″ | 60 | 84 | 84 | 84 | 75 | 84 | 200 | 110 | 40 | 11/2″ | 70 | 94 | 94 | 94 | 85 | 89 | 250 | 120 | 50 | 2 | 80 | 109 | 109 | 109 | 103 | 104 | 250 | 130 | 65 | 21/2″ | 110 | 129 | 129 | 129 | 122 | 124 | 350 | 140 | 80 | 3 | 120 | 144 | 144 | 144 | 135 | 134 | 350 | 150 | 100 | 4 | 140 | 164 | 164 | 170 | 173 | 159 | 240 | 180 | 注:系列阀门主要零部件及密封面的材质可根据实际工况条件或用户特殊要求设计选用.
