沟槽式（卡箍）连接阀门是引进美国与德国同类产品而设计制造的一系列新型连接阀门。它具有安装快速,简易,安全,可靠,不受安装场地限制,便于管道与阀门的维修保养,有隔振隔音与一定的角度范围内有克服管道连接不同轴耐用产生仿差,震决温差所产生热胀冷缩等优点。
广泛应用于输送流体管道的给排水,消防,空调,燃气,石油,化工,水处理,市政,造船等管道工程作为控制流体作用。 | 主要技术参数Main technical parameters | 公称压力Nominal pressure | 1.0 | 1.6 | 2.5 | | 试验压力 test pressure | 壳体强度 shell trength | 1.5 | 2.4 | 3.75 | | 密封性能Sealing performance | 1.1 | 1.76 | 2.75 | | 适用介质suitable Media | 产品类型Product type | 铸铁,球墨铸铁Castiron, ductile iron | 铜Copper | 碳钢carbon steel | 不锈钢Stainless Steel | | 适用介质Suitable Media | 水,水蒸汽,油品,空气Water steam oil air | 水,水蒸汽Water,water vapor | 水,水蒸汽,油品,空气water steam oil air | 硝酸类Nitric acid | | 工作温度 work temperature | 密封面介质Sealing surface of the medium | 橡胶Rubber | 乙腈胶橡Acetonitrile Rubber | 乙丙橡胶EPDM | 氟橡胶Viton | 聚四氟塑料PTFE plastic | 铜Copper | 不锈钢Stainless Steel | | 工作温度 work temperature | ≤60 | ≤80 | ≤250 | ≤250 | ≤200 | ≤200 | ≤200 | 主要零件材料Main parts materia | 产品类型 Product Type | 材质Material | | 阀体Body | 阀板Valve plate | 阀轴Valve shaft | 密封面Sealing surface | | 铸铁Cast iron | HT200 | 球铁,碳钢,喷涂或不锈钢Ductile iron,carbon steel or stainless steel spray | 铬不锈钢Chromium Stainless Steel | 铜或不锈钢Copper or Stainless Steel | 橡胶NBR,丁腈橡胶NBR,乙丙EPOM 氟橡胶PTFE,聚四氟塑料F46 | | 球墨铸铁 ductile iron | QT450 | 球铁,碳钢,喷涂或不锈钢Ductile iron,carbon steel or stainless steel spray | 铬不锈钢Chromium Stainless Steel | 铜或不锈钢Copper or Stainless Steel | | 铜Copper | 铜Copper | 铜或不锈钢Copper or Stainless Steel | 铬不锈钢Chromium Stainless Steel | 铜Copper | | 碳钢carbon steel | WCB | 球铁,碳钢,喷涂或不锈钢Ductile iron,carbon steel or stainless steel spray | 铬不锈钢Chromium Stainless Steel | 铜或不锈钢Copper or Stainless Steel | | 不锈钢Stainless Steel | 1Cr18Ni9T1（304） | 不锈钢Stainless Steel | 不锈钢Stainless Steel | 不锈钢Stainless Steel | 主要外型尺寸External dimensions | 公称通径/名称 | 50 | 65 | 80 | 100 | 125 | 150 | 200 | 250 | 300 | 350 | 400 | 425 | 500 | 600 | | | D | 57 | 60 | 76 | 89 | 108 | 114 | 133 | 140 | 159 | 165 | 168 | 219 | 273 | 325 | 377 | 426 | 480 | 530 | 630 | SJKD3型 | | A1 | 14.5 | 14.5 | 14.5 | 16 | 16 | 16 | 19 | 19 | 19 | 25 | 25 | 25 | 25 | 25 | | | B1 | 9.5 | 9.5 | 9.5 | 9.5 | 9.5 | 9.5 | 13 | 13 | 13 | 13 | 13 | 13 | 13 | 13 | | | C | 2.2 | 2.2 | 2.2 | 9.5 | 2.2 | 2.2 | 2.5 | 2.5 | 3.3 | 3.3 | 5.5 | 5.5 | 55 | 55 | | | D381X D81X | L | 88 | 90 | 96 | 115 | | 132 | 159 | 159 | 165 | 165 | 170 | 180 | 190 | 210 | | | H1 | 60 | 75 | 80 | 94 | | 125 | 220 | 220 | 250 | 265 | 300 | 330 | 350 | 410 | | | H0 | 220 | 245 | 270 | 300 | | 350 | 600 | 600 | 740 | 765 | 875 | 940 | 995 | 1130 | | | E | 245 | 245 | 245 | 245 | | 245 | 260 | 260 | 330 | 330 | 425 | 425 | 425 | 425 | | | F | 65 | 65 | 65 | 65 | | 65 | 90 | 125 | 180 | 190 | 210 | 210 | 210 | 210 | | | D0 | 120 | 120 | 120 | 120 | | 140 | 140 | 140 | 240 | 280 | 320 | 320 | 350 | 350 | SJKD3型 | |
