Z41H金属密封柱塞式闸阀金属密封柱塞式闸阀采用国标闸阀尺寸设计的非金属密封法兰连接腰鼓形柱塞闸阀和金属密封法兰连接腰鼓形柱塞闸阀的手轮操作机构有两种形式，一种如图六、图八所示，另一种新形式如图七所示，即手轮只转动而不做上、下运动而阀杆只做上下运动而不转动。当阀门全开时阀杆伸长至最高点，但还是在保护套内。这种手轮的操作机构优点如下：1、手轮不上、下运动所占用的空间小，适合装在空间紧凑的管路系统中。2、手轮上的转动扭矩，不直接作用在阀杆上，则阀杆不易产生弯曲变形，而转动扭矩小。3、阀杆在保护套中上、下运动，与外界隔离，适用于室外安装，避免了大气中吹来的风沙所磨损以及酸碱物质的腐蚀。主要连接、结构尺寸：DN(mm)尺寸（mm）UZ41H-16C（Y、P、R）1520253240506580100125150200250300350400L130150160180240250265280300325350400450500550600W100100120140160180200240270310340400520640760900D95105115135145160180195215245280335405460520580K657585100110125145160180210240295355410470525D14555657885100120135155185210265320375435485t14141416161618202022242630303436n-φ4-144-144-144-184-184-184-188-188-188-188-238-2312-2312-2516-2516-30DN(mm)尺寸（mm）UZ41H-25C（Y、P、R）1520253240506580100125150200250300350400L130150160180240250265280300325350400450500550600W100100120140160180200240280310340400520640760900D95105115135145160180195230270300360425485550610K657585100110125145160190220250310370430490550D14555657885100120135160188218278332390448505t16161618182022222428303436404448n-φ4-144-144-144-184-184-188-188-188-238-258-2512-2512-3016-3016-3416-34DN(mm)尺寸（mm）UZ41H-40C（Y、P、R）1520253240506580100125150200250300350400L130150160180200250265280300325350400450500550600W100100120140160180200240280310340400520640760900D95105115135145160180195230270300375445510570655K657585100110125145160190220250320385450510585D14555657885100120135160188218282345408465535t16161618182022222428303842465258n-φ4-144-144-144-184-184-188-188-188-128-268-2612-3012-3316-3316-3616-39DN(mm)尺寸（mm）UZ41H-64C（Y、R、P）506580100125150200L250280310350400450550W200240280310340400520D175200210250295340405K135160170200240280345D1105130140168202240300t26283032363844n-φ4-238-238-238-258-308-3412-34DN(mm)尺寸（mm）UZ41H-100C（Y、R、P）506580100125150200L250280310350400450550W200240280310340400520D195220230285310350430K145170180210250290360D1112138148172210250312t28323438424054n-φ4-258-258-238-308-3412-3412-41)
