蜗轮传动不锈钢法兰式固定球阀.doc

蜗轮传动不锈钢法兰式固定球阀Q347F/H/Y适用于化工、石油、天然气、冶金、等行业及含硫化氢介质、杂质多、腐蚀严重的天然气长输管。 【蜗轮传动不锈钢法兰式固定球阀产品特点】1、阀座采用弹簧结构，将阀座推向球体，保证了良好的低压密封性能2、固定球阀阀前，阀后阀座都能密封，即所谓双向密封特性，利用自带的排放阀，阀体中腔可向外排放3、枢轴采用防吹出保护结构，低摩擦系数的轴承等。具有性能优异，可靠性高，用途广泛4、整体结构具有全通道、紧急密封、防火等特点。5、全通径阀门流道孔直径与管和径内径一致，更于管线清扫。6、阻塞与排泄阀门处于关闭状态时，上下游侧的阀座使流体阻断，阀体中腔的积治物可以排泄，排泄装置如下机能： 事前可检查阀座是否泄漏损伤；减少介质更换对阀门的污染； 在工作压力下，阀门处于全开或全关状态时，可更换阀杆部填料函。（如图5所示排泄装置是排污塞）7、自动泄压阀门中腔停滞的介质由于温度升高，而出现异常升高时，阀座或阀体上安装的安全阀可以自动泄压。8、防火结构采用双重密封，当发生火灾时，非金属阀座烧损后，介质将球体压紧在阀体上的金属密封面阻止介质大量漏出，符合API607规定。9、紧急密封阀座及阀杆密封件出现损伤而引起泄漏时，通过注脂阀注入密封脂可以起瞬时应急密封作用。10、阀杆加长阀杆加长适用于地下安装及低温介质用，加长尺寸，根据需要确定。操作方式有手动、气动、电动、气液联动、液动等。 蜗轮传动不锈钢法兰式固定球阀主要零件材料：零件名称普通碳素钢系列不锈钢系列低温钢系列抗硫系列Gb标准NACE标准阀体、左体、底盖A216-WCBA351-CF8、CF8M、CF3、CF3MA352-LCB、LCCA216-WCBA351-CF8M球体A216-WCB+HCrA351-CF8、CF8M、CF3、CF3MA352-LCB、LCCA216-WCB+HCrA351-CF8M阀座PTFE；烧结碳纤维；金属+橡胶组件上、下阀杆A182-F6aA182-F304、316A182-6a318A182-F316阀座支承点 A182-F304、316LF2ZnA105ZnA182-F316阀杆填料PTFE；碳纤维上、下阀杆轴承、止推轴金属衬PTFE；烧结碳纤维填料压环A182-F6aA182-F6aA182-F304、316A182-F6aA182-F6aA182-F316弹簧3yc-7双头螺柱A193-B7A193-B8 B8MA320-17A193-B7A193-B7螺母A194-2HA193-8MA194-4A194-2HA194-2H压盖A216-WCB,A105排污塞A105A182-F304、316Lf2A105A182-F316蜗轮传动不锈钢法兰式固定球阀主要连接尺寸：PN1.6MPa 公称通径5065801001251502002503003504004505006007008009001000D1516476102127152203254305337387438489591686781876978L17819120322935639445753361068676286491410671245137215241753H110211412715218421927336439543047055058070080095011001200H210712515217830033039849558062567069884010501100115012471374E 1161161711712572572571508383123123F 350350420420400400400410650650735735W23040040065010501050600600800800800800800800800800800800W(kg)121622355874205322460576864128016003450450594075409320PN2.5MPa 公称通径5065801001251502002503003504004505006007008009001000D1516476102127152203254305337387438489591686781876978L17824128330538140350256864876283891499111431346152417271880H110211412715218421927336439543047055058070080095011001200H210712515217830033038949558062567069884010501100115012471374E 1161161711712572572571508383123123F 350350420420400400400410650650735735W23040040065010501050600600800800800800800800800800800800W(kg)1524305587118255370533640103015422100420053007860868410300PN4.0MPa 公称通径5065801001251502002503003504004505006007008009001000D1516476102127152203254305337387438489591686781876978L17824128330538140350256864876283891499111431346152417271880H110211412715218421927336439543047055058070080095011001200H210712515217830033038949558062567069884010501100115012471374E 1161161711712572572571508383123123F 350350420420400400400410650650735735W23040040065010501050600600800800800800800800800800800800W(kg)1524305587118255370533640103015422100420053007860868410300PN6.4MPa公称通径506580100150200250300350400500600700D1516476102152203254305337387489591686L292330356406495597673762826902105412321397H1114124133159250294395445500530660800900H210815519723530037444551255061581010101180E 11611617117125725725715083123F 350350420420400400400410650735W650650650600600800800800800800800800800W(kg)2335499119235564088011001540280053005700PN10.0MPa 公称通径506580100150200250300350400500600700D1516476102152203254305337387489591686L292330356432559660787838889991119413971549H1114124133159250294395445500530660800900H210815519723530037444551255061
