价格:500.00
产品名称:锻钢固定球阀产品型号:Q47F公称通径:DN50~DN1200结构形式:球形公称压力:1.6Mpa~32.0Mpa连接方式:法兰适用温度:-20~180℃驱动方式:手动、电动、气动阀体材质:A105锻钢、WCB铸钢、不锈钢制造标准:国标GB、德国DIN、美国API、ANSI适用介质:水、油、燃气、气体及某些腐蚀性液体生产厂家:上海剑阀阀门有限公司产品说明Q47F锻钢固定球阀是新一代高性能球阀,适用于长输管线和一般工业管线,其强度、安全性、耐恶劣环境性等在设计时进行了特殊考虑,适用于各种腐蚀性和非腐蚀性介质。它与浮动球阀相比,工作时,阀前流体压力在球体上产生的作用力全部传递给轴承,不会使球体向阀座移动,因而阀座变形小,密封性能稳定、使用寿命长,适用于高压、大口径场合。先进的弹簧预阀座组件,具有自紧特性,实现上游密封。每阀有两个阀座,每个方向都能密封因而安装没有流向限制,是双向。本阀有二块式和三块式两种阀体结构,中法兰用螺栓连接,密封采用增强聚四氟乙烯镶入不锈钢圈内,钢圈后部设有弹簧保证阀座紧贴球体,保持密封。上下阀杆均设有PTFE轴承,减少磨擦,操作省力,小轴底部没有调整片,保证球与密封圈的接处位置。采用全通径的结构使阀门流量孔么与管线内径一致,以便管线清扫。产品特征1、结构特点:固定球阀球体带有固定轴的球阀,称为固定球阀。固定球阀主要用于高压大口径。根据阀座密封圈的安装不同,固定球阀可以有两种结构:球体前密封的阀座,球体后密封的阀座2、整体结构:具有全通道、紧急密封、防火等特点。3、全通径:阀门流道孔直径与管和径内径一致,更于管线清扫。4、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:①事前可检查阀座是否泄漏损伤;②减少介质更换对阀门的污染;③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)5、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。6、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。7、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。8、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。主要性能参数试验压力(MPa)公称压力(MPa)压力级(Class)1.62.54.06.410.016.025.01503004006009001500强度试验2.43.86.09.615.02437.53.17.810.215.323.138.4密封试验1.82.84.47.011.017.627.52.25.67.511.216.828.1气密试验0.5-0.7工作温度PTEE≤150℃PPLE≤300℃碳纤≤350℃适用介质C:水、油、气体、蒸气P:硝酸类(温度≤200℃)R:醋酸类(温度≤200℃)主要零部件材质序号零件名称材质GBASTM1阀体WCB、A105A182F3162弹簧60Si2Mn3163密封圈增强聚四氟乙烯增强聚四氟乙烯4垫片柔性石墨+不锈钢柔性石墨+3165排污螺塞253166O型密封圈橡胶橡胶7底盖A1053168螺钉353169阀杆2Cr13+镀镍磷31610滑动轴承不锈钢+PTFE316+TPFE11球体A105+镀镍磷A182F31612阀座A105+镀镍磷31613螺柱35CrMoA31614螺母3531615压套A10531616填料PTFEPTFE17填料压盖WCBA216-WCB18键45316外形结构图Q47、Q347型ANSICLASS150LB-1500LB主要尺寸及重量■CLASS150公称通径2"21/2"3"4"5"6"8"10"12"14"16"18"20"24"28"32"36"40"D1516476102127152203254305337387438489591686781876978LRF17819128322935639445753361068676286491410671245137215421753BW21624128330538145752155963576283891499111431346154217271880H110211412715218421927336039543047055058070080095011001200H210712515217830033039849558062567069884010501100115012471374E1161161711712572572571508383123123F350350420420400400400410650650735735W23040040065010501050600600800800800500800800800800800800W(kg)1216223558742053224605768641280160035404500594075409320■CLASS300公称通径2"21/2"3"4"5"6"8"10"12"14"16"18"20"24"28"32"36"40"D1516476102127152203254305337387438489591686781876978LRF21624128330538145752155963576283891499111431346154217241887BW21624128330538145752155963576283891499111431346154217271880H110211412715218421927336039543047058058070080095011001200H210712515217830033039849558062567084084010501100115012471374E1161161711712572572571508383123123F350350420420400400400410650650735735W23040040065010501050600600800800800800800800800800800800W(kg)1524305587118255370533640103015422100420053007860868410300■CLASS400公称通径2"21/2"3"4"6"8"10"12"14"16"20"24"28"D1516476102152203254305337387489591686LRF292330356406495597673762826902105412321397BW295333359410498600676765829905106012411410H1114124133159250294395445500530660800900H210815519723530037444551255061581010101180E11611611611611617117125725725715083123F350350350350350420420400400400410650735W600600600600600800800800800800800800800W(kg)2335499119235564088011001540280053005700■CLASS600公称通径2"21/2"3"4"6"8"10"12"14"16"20"24"28"D1516476102152203254305337387489591686LRF292330356432559597787838889991119413971549BW295333359435562600791841892994120014071562H1114124133159250294395445500530660800900H210815519723530037444551255061581010101180E11611611611611617117125725725715083123F350350350350350420420400400400410650735W600600600600600800800800800800800800800W(kg)35385510223239071096017001970325058006700■CLASS900公称通径2"21/2"3"4"6"8"10"12"14"16"18"20"24"D1516476102152203254305324375426473572LRF36841938145761073783896510291130121913211549BW37142238446061374084196810381140123213341568H1217241259297360322420470510600700720810H2126158191216270394502572675762866894956E116116116116171171257257150150180180220F350350350350420420420400410410650650735W600600600600800800800800800800800800800W(kg)506080125270■CLASS1500公称通径2"21/2"3"4"6"8"10"12"14"16"18"20"24"D1516476102146194241289318362395440504LRF368419381546705832991113012571384153716641689BW3714223845497119411000114612761407155916861902H1126158191216296378495542590670710750850H22172412592973654755786967618319009501080E116116116116171257257150150180220220280F350350350350420400400410410650735735735W600600600600800800800800800800800800800W(kg)5075117216380Q47F锻钢固定球阀http:///html/76.html)
