吉林销售截止阀厂家

欧通截止阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质由阀瓣下方进入阀门时，操作力所需要克服的阻力，是阀杆和填料的摩擦力

与由介质的压力所产生的推力，关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。按连接方式分为三种：法兰连接、丝扣连接、焊接连接。从自密封的阀门出现后，截止阀的介质流向就改由阀瓣上方进入阀腔，这时在介质压力作用下，关阀门的力小，而开阀门的力大，阀杆的直径可以相应地减少。同时，在介质作用下，这种形式的阀门也较严密。系列产品：进口截止阀、高压截止阀。高温截止阀。高压高温截止阀。电动截止阀J941H/J961Y。气动截止阀J641H。气动角座阀。日标截止阀J41W。德标截止阀。美标截止阀J41W。保温截止阀BJ41H/BJ45。高温截止阀J41Y/J61Y。高压截止阀J41H、对焊截止阀J61Y/J65Y/J64H。高温高压截止阀。Y形截止阀J45/J65Y。自密封截止阀J41W/J61W。黄铜截止阀J11W。铸铁截止阀J41TW。铸钢截止阀J41H。锻钢截止阀。不锈钢截止阀J41W。铬钼钢截止阀J41Y-100I。波纹管截止阀WJ41/WJ44/WJ61H、保温波纹管截止阀BWJ41W。丝口截止阀J11W。法兰截止阀J41。氧气截止阀JY41W。真空截止阀NKJ41H/44H/J61。水封截止阀DS41H/DS61H。伞齿轮截止阀J541H。氨用截止阀J41B/J42B/J61B/J21B/J11B。角式截止阀J44H。衬氟截止阀J41F4/J45F4。衬胶截上阀J41J/J45J。塑料截止阀J41F-6S、J11F-6S。液化气截止阀J41F。天燃气截止阀J41N。低温截止阀DJ41W。撞击式大口径截止阀。蒸汽截止阀。斯派沙克式截止阀。节流阀、高压节流阀、截止节流平衡阀L41Y/L44Y/L46Y/L86Y/L87Y/L66Y/L67Y/L47Y。节流截止放空阀FJ41Y。节流截止排污阀TPJ41Y。 阀体的材质有: 铸铁、铸钢、不锈钢、锻钢、铬钼钢、铬钼钒钢。工作压力1.6-32MPA(美标从150LB-2500LB，日标从10K-64K)。工作温度-20
