对夹式多层次硬密封蝶阀D373H:产品特点1、多层次硬密封蝶阀密封是采用软硬层金属片层叠组成，通过高精度机械加工成形，嵌装在碟板上与阀座吻合，具有金属密封和弹性密封的双重优点，无论在低温和高温情况下，均具有优良的密封特性。2、采用三维偏心结构阀座与碟板几乎无摩擦，具有越关越紧的密封功能。3、结构独特，操作灵活、省力、方便、不受介质压力的高、低影响，密封性能可靠，使用寿命长。4、蝶阀设有密封调节装置，长期使用后若密封性能下降，可调节碟板密封圈向阀座靠近即可恢复原有密封性能，大大地提高使用寿命。详见密封示意（图1）■采用标准设计与制造：GB12238-89JB/T8527-97结构长度：GB12221-89压力-温度等级：JB/T74Gb9131HGJ67法兰标准：GB9113.1～GB9113.26GB9115.1～GB9115.36JB/T174～JB/T90压力试验：GB/T13927-92■主要技术参数公称通径DN（mm）DN（mm）50～200050～200公称压力PN（Mpa）PN（Mpa）0.61.01.62.54.0密封试验Ps（Mpa）强度试验0.91.52.43.756.0密封试验0.661.11.762.754.4气密封试验0.60.60.60.60.6渗漏率水、气、油品等适用温度碳钢-29℃～425℃不锈钢–40℃～600℃适用介质空气、水、蒸汽、煤气、油品以及酸、碱、盐带有弱腐蚀性介质驱动型式蜗杆蜗轮传动、气传动、电传动■主要零部件材料零件名称材料阀体铸钢、不锈钢、铬钼钢、合金钢蝶板铸钢、不锈钢、铬钼钢、合金钢阀杆2Cr13、1Cr13不锈钢、铬钼钢密封闸不锈钢与耐高温石棉组合成多层次轴承奥氏体不锈钢、304氮化ZG00Cr18Ni304填料柔性石墨■蜗轮传动多层次金属硬密封蝶阀■蜗轮传动蝶阀主要外形和连接尺寸H6■CHY.D373-（C、I、P、R）F10公称通径DN结构长度（标准值）外形尺寸（参考值）法兰尺寸和螺栓孔尺寸（标准值）参考重量0.6Mpa1.0Mpa毫米mm英尺inchLHH1A1B1D1Z-dD1Z-d（Kg）502431123501802001104-141254-18126521/2461153701802001304-141454-1813803641203801802001504-181608-18151004641384201802001704-181808-18171255701644601802002008-182108-18271506761755552702802258-182408-22292008892157804004252808-182958-22452501011424384040042533512-1835012-22693001211428599545056039512-1840012-228635014127320105045056044512-2246016-2212240016140350122053558049516-2251516-2614145018152350128053558055016-2256520-2619150020152380136553558060020-2262020-2626060024154435146057066070520-2672520-3038070028165480152075055081024-2684024-3045080032190530171075055092024-3095024-33650900362035951810750550102024-30105028-338301000402166501900900750112028-30116029-36105012004825477522801000925134032-33138032-39140014005627987024501000925156036-36159036-421900160064318100027301000925176040-36182040-482900180072356111030201100980197044-39202044-484000200080406125032701100980218048-42223048-485300用户注意：表中H1可根据用户需要加长（长杆蝶阀），如需特殊材料订货时提出。■蜗轮传动多层次金属硬密封蝶阀■蜗轮传动蝶阀主要外形和连接尺寸H16■CHY.D373-（C、I、P、R）F25公称通径DN结构长度（标准值）外形尺寸（参考值）法兰尺寸和螺栓孔尺寸（标准值）参考重量PN1.6MpaPN2.5Mpa毫米mm英尺inchLHH1A1B1D1Z-dD1Z-d（Kg）502431123501802001254-181254-18126521/2461153701802001454-181458-1813803641203801802001608-181608-18151004641384201802001808-181908-22171255701644601802002108-182208-26271506761755552702802408-222508-262920088921578040042529512-2231012-26452501011424384040042535512-2637012-30693001211428599545056031012-2643016-308635014127320105045056047016-2649016-3312240016140350122053558052516-3055016-3614145018152350128053558058520-3060020-3619150020152380136553558065020-3366020-3626060024154435146057066077020-3677020-3938070028165480152075055084024-3687524-4245080032190530171075055095024-3999024-48650900362035951810750550105028-39109028-488301000402166501900900750117028-42121028-56105012004825477522801000925139032-48142032-56140014005627987024501000925159036-48164036-621900160064318100027301000925182040-56186040-622900180072356111030201100980202044-56207044-704000200080406125032701100980223048-62230048-705300用户注意：表中H1均可根据用户需要加长（长杆蝶阀），如需特殊材料订货时提出。■主要外形和连接尺寸■D373H-40（C、I、P、R）公称通径DN结构长度（标准值）外形尺寸（参考值）法兰尺寸和螺栓孔尺寸（标准值）PN40Mpa毫米mm英尺inchLHH1A1B1D1Z-d502431123501802001254-186521/2461153702702801458-18803641203802702801608-181004641384202702801908-221255701644603804202208-261506761755553804202508-2620088920878040042532012-30
