詳情介紹

電動(dòng)截止閥屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí)，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開(kāi)閥門的力大，所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。近年來(lái)，從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門的力小，而開(kāi)閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時(shí)，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)密。我國(guó)閥門“三給”曾規(guī)定，截止閥的流向，一律采用自上而下。電動(dòng)截止閥開(kāi)啟時(shí)，閥瓣的開(kāi)啟高度，為公稱直徑的25%～30%時(shí)，流量已達(dá)到最大，表示閥門已達(dá)全開(kāi)位置。所以截止閥的全開(kāi)位置，應(yīng)由閥瓣的行程來(lái)決定。設(shè)計(jì)與制造 Design and Manufacture結(jié)構(gòu)長(zhǎng)度Face To Face法蘭尺寸Flange Dimension壓力-溫度 Pressure Temperature Lating試驗(yàn)-檢驗(yàn) Inspection And TestGB122235GB12221GB9113 JB79GB9131GB/T13927 JB/T9092電動(dòng)截止閥壓力試驗(yàn)公稱壓力NominalPressure1.62.54.06.410.016.0強(qiáng)度試驗(yàn) Shell Test2.43.86.09.615.024.0水密封試驗(yàn) Water Seal Test1.82.84.47.011.018.0上密封試驗(yàn)Backseat Test1.82.84.47.011.018.0氣密封試驗(yàn) Air Seal Test0.5-0.7電動(dòng)截止閥主要零件材料及性能體、蓋、板 Body Cover Disc閥桿Stem密封面 Sealing Face墊片Sealing　Shim填料Packing工作溫度℃ Working Temperature適用介質(zhì)Suitable MediumWCB2Cr1313CrSTL木體材料With BodyMaterial尼龍Nylon增強(qiáng)柔性石墨Enhanced Flexible Graphite13Cr/柔性石墨1Cr13/Flexible Graphite08軟鋼08 Soft Steal0Cr18Ni9Ti0Cr17Ni12Mo2TiXD550F(T)PTFE柔性石墨增強(qiáng)柔性石墨Flexible GraphiteEnhanced Flexible GraphiteSFB/260SFP/260PTFE≤425水蒸汽油品WaterSteamPetroleumPtoductsWC138CrMoAl25Cr2MoV≤450WC6≤540WC9≤570C5 C12≤540ZGCr5Mo≤200硝類Nitric acidZG1Cr18Ni9Ti1Cr18Ni9Ti≤200醋類Acetic acidZG1Cr18Ni12Mo2Ti1Cr18Ni12Mo2Ti電動(dòng)截止閥規(guī)格 主要尺寸和重量1.6MPaDNLDD1D2bn-φdHDo重量 Weight凸面法蘭RFJ941HJ941YJ941WJ941FJ941N16C16P16R16I10130906040144-141981204.915130956545144-142181205.3201501057555144-142581407.0251601158565144-142751607.432180135100781-182801808.340200145110851-1833020012.6502301601251001-183502401465290180145120184-1840028022.780310195160135208-1835528029100350215180155208-1841532032.8125400245210185228-1846036079.5150480280240210248-23510400932006003352952652612-237104001792506224053553203012-2578504413006984604103753012-259255006電動(dòng)截止閥規(guī)格 主要尺寸和重量2.5MPaDNLDD1D2bn-φdHDo重量 Weight凸面法蘭RFJ941HJ941YJ941WJ941FJ941N16C16P16R16I101309060401-141981204.9151309565451-142181205.32015010575551-142581407.02516011585651-142751607.43218013510078184-182801808.34020014511085184-1833020012.650230160125100208-183502401665290180145120228-184002802580310195160135228-2335528030100350230190160248-2541532034.8125400270220188288-2546036089.51504803002502183012-25510400992006003603102783412-257104001812506224253703323612-3078504453006984854303904016-30925500651電動(dòng)截止閥規(guī)格 主要尺寸和重量4.0MPaDNLDD1D2bn-φdHD0重量Weight凹凸法蘭 MFMJ941H J941Y J941W J941F J941N40 40P 40R 40I2015010575511-1427514072516011585581-1428516093218013510066184-18302180124020014511076184-18355200175023016012588204-183732402465290180145110228-184082803380310195160121228-1843632044100350230190150248-2348036060125400270220176288-2558840090150480300250204308-256114001002005333753202603812-307204001906.4MPa201901259051204-1822816013凹凸法蘭 MFMJ941H J941Y J941W J941F J941N40 40P 40R 40I2521013510058224-18275180153223015011066244-23325200194026016512576244-233602402550300175135882-234102803565340200160110288-234503204880380210170121308-2348536056100430250200150328-25537400125125500295240176368-30631400130150550340280204388-34501602006504053452604412-3481350028510.0MPa101701007035204-141981206凹凸法蘭 MFMJ941H J941Y J941W J941F J941N100 100P 100R 100I151701057540204-1420214011201901259051224-18228160132521013510058244-18250180143223015011066244-2332622010260165125762-23359240305030019514588284-254142805065340220170110328-254343206580380230180121348-255474000430265210150388-306214501161255003102501728-347324501501505503502902044612-348405003002006504303602605412-4192555060016.0151701107540244-1814814012環(huán)槽法蘭 RTJ J941H J941Y J941W160 160P 160R 160I2019013090512-23156160152521014010058284-23175180173223016511566304-25200200214026017512576324-27231240315030021516588368-252622505365340245190110448-303033207080380260205121468-303414000430300240150488-34485450120

電動(dòng)截止閥屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí)，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開(kāi)閥門的力大，所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。近年來(lái)，從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門的力小，而開(kāi)閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時(shí)，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)密。我國(guó)閥門“三給”曾規(guī)定，截止閥的流向，一律采用自上而下。電動(dòng)截止閥開(kāi)啟時(shí)，閥瓣的開(kāi)啟高度，為公稱直徑的25%～30%時(shí)，流量已達(dá)到最大，表示閥門已達(dá)全開(kāi)位置。所以截止閥的全開(kāi)位置，應(yīng)由閥瓣的行程來(lái)決定。設(shè)計(jì)與制造 Design and Manufacture結(jié)構(gòu)長(zhǎng)度Face To Face法蘭尺寸Flange Dimension壓力-溫度 Pressure Temperature Lating試驗(yàn)-檢驗(yàn) Inspection And TestGB122235GB12221GB9113 JB79GB9131GB/T13927 JB/T9092電動(dòng)截止閥壓力試驗(yàn)公稱壓力NominalPressure1.62.54.06.410.016.0強(qiáng)度試驗(yàn) Shell Test2.43.86.09.615.024.0水密封試驗(yàn) Water Seal Test1.82.84.47.011.018.0上密封試驗(yàn)Backseat Test1.82.84.47.011.018.0氣密封試驗(yàn) Air Seal Test0.5-0.7電動(dòng)截止閥主要零件材料及性能體、蓋、板 Body Cover Disc閥桿Stem密封面 Sealing Face墊片Sealing　Shim填料Packing工作溫度℃ Working Temperature適用介質(zhì)Suitable MediumWCB2Cr1313CrSTL木體材料With BodyMaterial尼龍Nylon增強(qiáng)柔性石墨Enhanced Flexible Graphite13Cr/柔性石墨1Cr13/Flexible Graphite08軟鋼08 Soft Steal0Cr18Ni9Ti0Cr17Ni12Mo2TiXD550F(T)PTFE柔性石墨增強(qiáng)柔性石墨Flexible GraphiteEnhanced Flexible GraphiteSFB/260SFP/260PTFE　　≤425水蒸汽油品WaterSteamPetroleumPtoductsWC138CrMoAl25Cr2MoV≤450WC6≤540WC9≤570C5 C12≤540ZGCr5Mo≤200硝類Nitric acidZG1Cr18Ni9Ti1Cr18Ni9Ti≤200醋類Acetic acidZG1Cr18Ni12Mo2Ti1Cr18Ni12Mo2Ti電動(dòng)截止閥規(guī)格 主要尺寸和重量1.6MPaDNLDD1D2bn-φdHDo重量 Weight凸面法蘭RFJ941HJ941YJ941WJ941FJ941N16C16P16R16I10130906040144-141981204.915130956545144-142181205.3201501057555144-142581407.0251601158565144-142751607.432180135100781-182801808.340200145110851-1833020012.6502301601251001-183502401465290180145120184-1840028022.780310195160135208-1835528029100350215180155208-1841532032.8125400245210185228-1846036079.5150480280240210248-23510400932006003352952652612-237104001792506224053553203012-2578504413006984604103753012-259255006電動(dòng)截止閥規(guī)格 主要尺寸和重量2.5MPaDNLDD1D2bn-φdHDo重量 Weight凸面法蘭RFJ941HJ941YJ941WJ941FJ941N16C16P16R16I101309060401-141981204.9151309565451-142181205.32015010575551-142581407.02516011585651-142751607.43218013510078184-182801808.34020014511085184-1833020012.650230160125100208-183502401665290180145120228-184002802580310195160135228-2335528030100350230190160248-2541532034.8125400270220188288-2546036089.51504803002502183012-25510400992006003603102783412-257104001812506224253703323612-3078504453006984854303904016-30925500651電動(dòng)截止閥規(guī)格 主要尺寸和重量4.0MPaDNLDD1D2bn-φdHD0重量Weight凹凸法蘭 MFMJ941H J941Y J941W J941F J941N40 40P 40R 40I2015010575511-1427514072516011585581-1428516093218013510066184-18302180124020014511076184-18355200175023016012588204-183732402465290180145110228-184082803380310195160121228-1843632044100350230190150248-2348036060125400270220176288-2558840090150480300250204308-256114001002005333753202603812-307204001906.4MPa201901259051204-1822816013凹凸法蘭 MFMJ941H J941Y J941W J941F J941N40 40P 40R 40I2521013510058224-18275180153223015011066244-23325200194026016512576244-233602402550300175135882-234102803565340200160110288-234503204880380210170121308-2348536056100430250200150328-25537400125125500295240176368-30631400130150550340280204388-34501602006504053452604412-3481350028510.0MPa101701007035204-141981206凹凸法蘭 MFMJ941H J941Y J941W J941F J941N100 100P 100R 100I　151701057540204-1420214011201901259051224-18228160132521013510058244-18250180143223015011066244-2332622010260165125762-23359240305030019514588284-254142805065340220170110328-254343206580380230180121348-255474000430265210150388-306214501161255003102501728-347324501501505503502902044612-348405003002006504303602605412-4192555060016.0151701107540244-1814814012環(huán)槽法蘭 RTJ J941H J941Y J941W160 160P 160R 160I2019013090512-23156160152521014010058284-23175180173223016511566304-25200200214026017512576324-27231240315030021516588368-252622505365340245190110448-303033207080380260205121468-303414000430300240150488-34485450120
