D343H三偏心硬密封蝶阀
价格:200.00
三偏心硬密封蝶阀概述:D343H三偏心硬密封蝶阀是劳伦斯阀门引进德国MAK公司技术开发的新一代蝶阀,产品性能优于国内外领先水平,广泛适用于冶金、石油、化工、电力、市政工程等工业管道上作截断或调节介质流量之用。三偏心硬密封蝶阀产品特点:1、结构尺寸短、体积小、重量轻、操作轻便、2、采用整轴结构,蝶板为行架式结构,蝶板强度高,过流面积大,流阻小、节省能源。3、独特的角偏心设计:本蝶阀在传统的双偏心结构基础上配置独特的角偏心设计,充分利用凸轮效应,从而实现阀门开启时,阀座与密封圈瞬时脱离,在90度行程上完全消除摩擦磨损。4、弹性金属对金属密封:蝶阀阀座表面堆焊耐温、耐腐蚀合金材料,密封圈由T形密封环两侧多层不锈钢片组成。在外加转矩的作用下,弹性密封圈与金属阀座之间的接触角产生轻微的契块效应,使得密封圈发生柔动和径向压缩,使得阀座360度周圈均匀密封比压,从而实现用最小的转矩实现最严密的关闭。三偏心硬密封蝶阀主要技术参数:公称通径DN(mm)50~2000公称压力PN(MPa)0.61.01.62.54.0试验压力强度试验0.91.52.43.756.0密封试验0.661.11.762.754.4气密封试验0.60.60.60.60.6适用介质水、蒸气、油品、酸类腐蚀性等。驱动方式手动、蜗轮传动、气动、电动适用温度碳钢:-29℃~550℃不锈钢-196℃~600℃三偏心硬密封蝶阀主要材料:零件名称材料阀体铸铁、不锈钢、铬钼钢、合金钢蝶板铸钢、合金钢、不锈钢、铬钼钢密封圈不锈钢与耐高温石棉板组合成多层次阀杆2Cr13、1Cr13不锈钢、铬钼钢填料柔性石墨D3(6、9)43H-6~10(C、P、R、V)连接尺寸:公称通径DN外形尺寸连接尺寸LHD343HD643HD943HPN0.6MPaPN1.0MPa短长H1A1B1H2A2B2H3A3B3DD1z-dDD1z-d50108150112350180200605245725302502551401104-141651254-1865112170115370180200625245725502502551601304-141851454-1880114180120380180200645245725652502551901504-182001608-18100127190138420180200675355926002502552101704-182201808-18125140200164460180200715355926402502552402008-182502108-18150140210175555270280800355927053003152652258-182852408-2220015223020860527028085025017077530031532028012-183402958-2225016525024368027028092525017094530031537533512-2239533012-223001782702838003804201035450220107030031544039512-2244540012-223501902903108353804201070450220114030031549044516-2250546016-224002163103409154504701190450280121030031554049516-2256551516-264502223303809604504701250650280133557571459555016-2261556520-2650022935041010204804901295650280141557571464560020-2267062020-2660026739047012256406601455850380160565681075570520-2678072520-3070029243055013556406601585850380184465681086081024-2689584024-30800318470640147064066017001250380204065681097592024-30101595024-3390033051071015458509001865125038022557858631075102024-301115105028-33100041055077017958509002015150058023807858631175112028-301230116028-36120047063089019658509002226150058026407858631405134032-331455138032-391400530710920238028861630156036-331675159036-4216006007901085295631561820176040-331915185040-5418006708701230322134212045197044-422115202044-5420007609501350348536852265218048-482325223044-54D3(6、9)43H-16~25(C、P、R、V)系列连接尺寸:通径DN外形尺寸连接尺寸LHD343HD643HD943HPN1.6MPaPN2.5MPa短长H1A1B1H2A2B2H3A3B3DD1z-dDD1z-d50108150112350180200605245725302502551651254-181651254-1865112170115370180200625245725502502551851454-181851458-1880114180120380180200645245725652502552001608-182001608-18100127190138420180200675355926002502552201808-182351908-22125140200164460180200715355926402502552502108-182702208-16150140210175555270280800355927053003152852408-223002508-1620015223020860527028085025017077530031534029512-2236031012-2625016525024368027028092525017094530031540535512-2642537012-303001782702838003804201035450220107030031546041012-2648543016-303501902903108353804201070450220114030031552047016-2655549016-334002163103409154504701190450280121030031558052516-3062055016-364502223303809604504701250650280133557571464058520-3067060020-3650022935041010204804901295650280141557571471065020-3373066020-3660026739047012256406601455850380160565681084077020-3684577020-3970029243055013556406601585850380184465681091084024-3696087524-428003184706401470640660170012503802040
