1、J941H-16CDN150结构特点、用途及注意事项“智高”系列J941H-16CDN150电动截止阀可以安装在管道的任何位置上，介质从下往上流。产品设计制造按国家标准GB12235,结构合理,密封可靠,性能优良,造型美观。合金钢截止阀适用于耐高温的蒸汽、油品管道上，具有耐高温特点。其特点如下：①阀瓣、阀座密封面用硬质合堆焊而成,耐磨、耐高温、耐腐蚀、抗擦伤性好、使用寿命长。②阀杆材料为渗氮钢，渗氮后的阀杆表面硬度高、耐磨、抗擦伤，抗腐蚀。③由于温度、压力等原因，阀门口径DN50以下的阀体、阀盖为模锻件、DN65以上的阀体、阀盖为铸钢件。④阀体材料品种齐全,填料、垫片可根据实际工况或用户要求合理选配,能适用与各种压力、温度及介质工况。⑤安装阀门时注意介质的流向，严格按阀门流向箭头指示的方向安装。⑥电动截止阀尽量垂直安装，阀杆向上。结构设计、特点及用途1．阀体和阀盖连接形式：PN10-64采用栓接阀盖；PN64-320采用自压密封式阀盖。2．阀杆螺母：通常情况下，阀杆螺母材料采用ASTMA439D2，同时可以根据用户要求采用铜合金等材料，对于大口径的截止阀，装滚动轴承，可以有效减小截止阀的开启力矩使阀门可以轻松开关。3．阀杆设计：采用整体锻造工艺制成，按照标准要求确定最小直径。阀盖垫片形式：PN10-64截止阀采用不锈钢石墨缠绕垫片；PN100截止阀可用不锈钢石墨缠绕垫片也可采用金属环垫片；PN160截止阀可采用金属环垫片，PN320截止阀采用自压密封金属环。4．截止阀结构特点：栓接阀盖，明杆支架和升降式阀杆金属封面。5．上密封座设计：我公司提供的所有截止阀都有倒密封设计，通常情况下，碳钢截止阀的阀座设计采用分离式倒密封结构，不锈钢截止阀的倒密封面非常可靠。虽然按照标准API600中有倒密封，但这不作为在带压情况下更换填料的依据。6．填料密封：通常采用成型柔性石墨作为填料材料，可根据用户需求提供PTFE或者复合填料材料。填料与填料函接触的表面粗糙度为3.2um，可以保证阀杆与填料接触面接合紧密但是旋转自如，经过精密的机械加工的阀杆密封面粗糙度0.8um可以保证阀杆可靠的密封。7．阀座：碳钢截止阀阀座通常采用锻钢材料，阀座密封面可根据客户需求喷焊硬质合金，NPS≤10″的截止采用分离式螺纹旋入式阀座，如果用户需要焊阀座结构也可提供；NPS≤12″截止阀采用焊阀座结构；不锈钢截止阀的阀座一般采用整体式或者在本体上焊硬质合金后直接加工阀座。如果用户有需求，不锈钢截止阀阀座也可采用分离式螺纹旋入式和焊接阀座结构。8．主要型号：J941H-10CDN32/J941H-10CDN40/J941H-10CDN50/J941H-10CDN65/J941H-10CDN80/J941H-10CDN100/J941H-10CDN125/J941H-10CDN150/J941H-10CDN200/J941H-10CDN250/J941H-10CDN300/J941H-10CDN350/J941H-10CDN400/J941H-10CDN450/J941H-10CDN500/J941H-10CDN600/J941H-10CDN700/J941H-10CDN800/J941H-10CDN900/J941H-10CDN1000J941H-16CDN32/J941H-16CDN40/J941H-16CDN50/J941H-16CDN65/J941H-16CDN80/J941H-16CDN100/J941H-16CDN125/J941H-16CDN150/J941H-16CDN200/J941H-16CDN250/J941H-16CDN300/J941H-16CDN350/J941H-16CDN400/J941H-16CDN450/J941H-16CDN500/J941H-16CDN600/J941H-16CDN700/J941H-16CDN800/J941H-16CDN900/J941H-16CDN1000J941H-25CDN32/J941H-25CDN40/J941H-25CDN50/J941H-25CDN65/J941H-25CDN80/J941H-25CDN100/J941H-25CDN125/J941H-25CDN150/J941H-25CDN200/J941H-25CDN250/J941H-25CDN300/J941H-25CDN350/J941H-25CDN400/J941H-25CDN450/J941H-25CDN500/J941H-25CDN600/J941H-25CDN700/J941H-25CDN800/J941H-25CDN900/J941H-25CDN1000J941H-40CDN32/J941H-40CDN40/J941H-40CDN50/J941H-40CDN65/J941H-40CDN80/J941H-40CDN100/J941H-40CDN125/J941H-40CDN150/J941H-40CDN200/J941H-40CDN250/J941H-40CDN300/J941H-40CDN350/J941H-40CDN400/J941H-40CDN450/J941H-40CDN500/J941H-40CDN600/J941H-40CDN700/J941H-40CDN800/J941H-40CDN900/J941H-40CDN1000J941H-64CDN32/J941H-64CDN40/J941H-64CDN50/J941H-64CDN65/J941H-64CDN80/J941H-64CDN100/J941H-64CDN125/J941H-64CDN150/J941H-64CDN200/J941H-64CDN250/J941H-64CDN300/J941H-64CDN350/J941H-64CDN400/J941H-64CDN450/J941H-64CDN500/J941H-64CDN600/J941H-64CDN700/J941H-64CDN800/J941H-64CDN900/J941H-64CDN1000J941H-16CDN150电动截止阀设计与制造GB/T12235连接端尺寸结构长度GB/T12221法兰尺寸JB/T79检验与试验JB/T9092材料碳钢GB/T12229不锈钢GB/T12230合金钢Q/ZB66标志GB/T12220供货JB/T7928J941H-16CDN150电动截止阀主要零件材料及主要用途阀体阀盖阀瓣密封圈阀杆填料适用介质适用温度(≤℃)WCBWCB+D507MOD5772Crl3柔性石墨水、油品、蒸汽425ZGlCrl8Ni9Ti0Crl8Ni9Ti+Stellite12Stellite6lCrl8Ni9TiPTFE硝酸类200ZGlCrl8Ni2Mo2TiCF8M+Stellite12lCrl8Ni2Mo2TilCrl8Ni2Mo2TiPTFE磷酸类、碱类、混酸200ZG00Crl7Nil4M02CF3M+Stellite12Stel1ite6316LPTFE磷酸类、尿素、甲铵液200ZGlCr5MOZGlCr5MO+Stellite12Stel1ite625Cr2Mo1VA柔性石墨水、油品、蒸汽550J941H-16CDN150电动截止阀主要外形尺寸、连接尺寸及质量公称压力PN(MPa)公称通径DN(mm)标准值参考值LDD1n2D6bff1Z-φdL1H质量(kg)1．6502301601251001634-φ1859064548652901801451201834-φ1859069060803101951601352038-φ18590715651003502151801552038-φ18590770711254002542101852238-φ185907801191504802802402102438-φ2359081021020060033529526526312-φ2381096732025062240535532030312-φ25810114355030069846041037530412-φ2583012927852.5502301601251002034-φ1859064550652901801451202238-φ1859069065803101951601352238-φ18590715671003502301901602438-φ23590770731254002702201882838-φ255907801271504803002502183038-φ2581081021520060036031027834312-φ2581096732225062242537033236312-φ30830114358530069848543039040416-φ3083012927954．0502301601251008820344-φ18590645616529018014512011022348-φ18590690758031019516013512122348-φ18590715841003502301901601502434．58-φ235907701011254002702201881762834．58-φ258107822071504803002502182043034．58-φ258108752262006003753202822603834．512-φ3081011603996．4503001751351058826344-φ23590710646534020016013011028348-φ23590750778038021017014012130348-φ23590785861004302502001681503234．58-φ258108371711255002952402021763634．58-φ3081010312431505503402802402043834．58-φ3483010662962006504053453002604434．512-φ34830121342010．0503001951451128828344-φ25590714816534022017013811032348-φ255907341028038023018014812134348-φ308108471751004302652101721503834．58-φ308109501941255003102502101764234．58-φ3483011412851505503502902502044634．512-φ3483012404502006504303603122605434．512-φ4l830142585016．0503002151651328836348-φ25590562926534024519015211044348-φ308107431658038026020516812146348-φ308308202161004303002402001504834．58-φ34830935238)
