• intros：{"brand_intro":"远大阀门集团创立于1994年，总部位于河北邢台，是中国最大的民营阀门制造商之一，年产能超50万台。公司以'高性价比+快速交付'著称，拥有亚洲最大的衬氟阀门自动化生产线。创始人闫国平从农机配件作坊起步，坚持'用普通材料做顶级耐腐蚀阀门'的逆向创新，通过优化衬里工艺将成本降低30%。远大品控引入德国TÜV莱茵认证，其衬氟蝶阀在环保水处理领域市占率连续五年第一。","product_intro":"D371F46-16C衬氟蝶阀定位中端市场，主打'轻量化与易维护'。阀体采用对夹式设计，重量仅为同规格截止阀的1/3，特别适合管道空间受限的环保工程。核心卖点是'双偏心密封结构'：蝶板与阀座在开启瞬间即脱离接触，减少衬氟层磨损，实测开关寿命达10万次以上。适用场景包括污水处理厂的加药系统、电厂的脱硫脱硝管道。相比竞争对手，远大提供'3年衬里脱落包换'服务，且支持48小时定制非标口径。","key_specs":{"公称通径":"DN50-DN600，覆盖主流管道尺寸","适用介质":"盐酸、硫酸、磷酸等，pH值1-14","阀板材质":"WCB+全衬FEP，耐腐蚀且刚性足","驱动方式":"手动/蜗轮/气动/电动，适配自动化需求","密封等级":"零泄漏（API 598标准），优于国标"}}
