產(chǎn)品概述Q41F型法蘭浮動球閥、不銹鋼法蘭球閥采用單斜面彈性密封圈或V型槽彈性密封圈結(jié)構(gòu)設(shè)計,當(dāng)介質(zhì)壓力較小時,密封圈與球體的接觸面積較小,因而有較大的密封比壓,確保可靠密封,介質(zhì)壓力較大時,密封圈與球體接觸面積增大,故密封圈能承受較大的介質(zhì)推力而不會損壞.由于聚四氟乙烯等密封圈材料具有良好的自潤滑性,與球體的摩擦損小,故球閥的使用壽命長。Q41F型法蘭浮動球閥、不銹鋼法蘭球閥適用于水、氣、油品、天然氣和酸堿腐蝕性介質(zhì)。適用溫度:-196~350℃驅(qū)動方式:手動、氣動、電動、液動等法蘭球閥規(guī)格:公稱通徑:DN?15-250?1/2"~10"永鵬機(jī)械球閥分類:浮動球閥、手動球閥、內(nèi)螺紋球閥、高壓對焊球閥、高壓氣動球閥、自鎖球閥、自來水電動球閥、自控球閥、自復(fù)位球閥、自動球閥、自動復(fù)位球閥、自動浮球閥、自保持電動球閥、自保持電磁球閥、球閥、鑄鐵絲扣球閥、鑄鐵絲口球閥、鑄鐵球閥、Q41浮動球閥、Q47固定球閥、法蘭球閥、V型球閥、卡套球閥、焊接球閥、美標(biāo)球閥、高壓球閥、高溫球閥、電動球閥、氣動球閥、黃銅球閥、不銹鋼球閥、天燃?xì)馇蜷y等?產(chǎn)品特點:1、*的閥座:聚多年球閥制造經(jīng)驗而設(shè)計的閥座,確保閥門密封,磨擦系數(shù)低,操作力矩小、多種閥座材料、適應(yīng)范圍廣。2、開關(guān)無誤的手柄:采用扁頭閥桿,與手柄的連接不會錯位,從而保證手柄指示的開關(guān)狀態(tài)與閥一致。3、鎖緊裝置:為防止閥門開關(guān)誤操作,在閥門全開、全關(guān)位置有鎖定孔,確保閥門處于正確的位置。4、法蘭浮動球閥、不銹鋼法蘭球閥閥桿防飛結(jié)構(gòu):閥桿為下裝式,防止受壓飛出,同時可在火災(zāi)后,與閥體形成金屬接觸,確保閥桿密封主要性能規(guī)范設(shè)計與制造結(jié)構(gòu)長度法蘭尺寸壓力-溫度試驗-檢驗GB122237GB12221GB9113?JB79GB9131GB/T13927?JB/T9092壓力試驗公稱壓力1.62.54.0強度試驗2.43.86.0水密封試驗1.82.84.4氣密封試驗0.4-0.7主要零件材料閥體?ZG1Cr18Ni9Ti?CF8CF3ZG1Cr18Ni12Mo2TiCF8MCF3M球體?閥桿?1Cr18Ni9Ti304304L1Cr18Ni12Mo2Ti?316316L閥?座聚四氟乙烯PTFE?加坡纖增強聚四氟乙烯PTFE+Glass?對位聚苯PPL?墊片聚四氟乙烯PTFE?不銹鋼/柔性石墨閥桿座聚四氟乙烯PTFE?不銹鋼/柔性石墨?填料聚四氟乙烯PTFE?增強柔性石墨?填料壓蓋?1Cr18Ni9Ti?304304L1Cr18Ni12Mo2Ti?316316L溫度-29~150(聚四氟乙烯?PTFE)?-29~200(加玻纖增強聚四氟乙烯?PTFE+GLASS)? -29~300(對位聚苯?PPL)?介質(zhì)水?蒸汽?油品硝酸類?強氧化介質(zhì)醋酸類?尿素類?介質(zhì)水?蒸汽?油品國標(biāo)主要外型尺寸1.6MPaDN?LDD1D2bn-φdHD0? ? ? 凸面法蘭?RF Q41F Q41PPL 16C 16P 16R15130956545144478140201401057555144484160251501158565144495180321651351007816481502504018014511085164815030050200160125100184817035065220180145120204819535080250195160135208821540010028021518015520882505001253202452101852288265600150360280240210248-232708002004003352952652612-2333012002.5MPa151309565451644103140? ? 凸面法蘭 RF Q41F Q41PPL 25 25P 25R20140105755516441121602515011585651644123180321651351007818481502504018014511085184815630050200160125100208817235065220180145120228819735080250195160135228-23222400100280230190160248-23253500125320270220188288-25275600150360300250218308-252868002004003603102783412-253401200
