產(chǎn)品詳細(xì)介紹 產(chǎn)品特點(diǎn)Features 該系列球閥特別適用于各焦化廠焦?fàn)t氨水、噴射循環(huán)系統(tǒng)高低壓轉(zhuǎn)換時(shí)使用。一、閥門的連接尺寸與原三通球閥相同，更換方便。二、特制的增強(qiáng)聚四氟乙烯封圈，其耐磨強(qiáng)度大大提高，顯著提高密封圈的使用壽命。三、獨(dú)特的內(nèi)部結(jié)構(gòu)，不僅大大降低了生產(chǎn)成本，而且使加工與維修更加簡(jiǎn)單化。四、帶倒密封結(jié)構(gòu)的下裝式閥桿，不僅防止了閥桿脫出，而且閥桿部位的密封更加可靠。五、外型結(jié)構(gòu)緊湊，獨(dú)特三塊式設(shè)計(jì)使閥門外觀更完美。 Thevalveseriesareespeciallyapplicableforthehigh/low-temperatureconversioncourseinsuchfieldsastheammoniawaterincokeovensortheinjectioncirculatingsystemincokeplants.1.Theconnectiondimensionofthevalveisidenticaltothatoftheabove-mentioned3-wayballvalveforconvenientreplacement.2.Thespecially-designedsealringmadefromstrongpolytetrafluoroethylenewithmuchgreaterabrasionstrengthcouldobviouslyenhancetheservicelifeofthering.3.Thespecialinteriorstructureappliednotonlyreducestheproductioncostbutalsosimplifiestheprocessingandmaintenancework.4.Thelower-loadingStemwithbackwardsealingconstructionnotonlypreventsthehandleformbacking-outbutalsoensuresthereliabilityofthescalingpartofthehandle.5.Withcompactstructureinconfiguration,thespecially-designed3-partfeaturemakesthevalvemuchmoreperfect. 產(chǎn)品型號(hào)Producttype 零件名稱Accessoryname 零件材料Accessorymaterial Q44M-40DN25 Q41F-40DN25 閥體、閥蓋body,Bonnet WCB 球體Ball 1Cr18Ni9Ti 閥桿Stem 2Cr13 密封圈Sealingring 增強(qiáng)聚四氟乙烯RPTFE 填料Stuffing V型聚四氟乙烯V-shapedPTFE 主要連接尺寸 公稱壓力PN(MPa)Nominalpressure 試驗(yàn)壓力(Mpa) 殼體Shell 高壓液密封閉High-pressureliquidsealing 低壓氣密封Low-pressurehermeticsealing 4.0 6.0 4.4 0.6 適用溫度Applicabletemperture ≤150℃ 氨水等Liquidammonia,etc.
