• intros：{"brand_intro":"远大阀门集团成立于1994年，位于河北石家庄，是中国最大的蝶阀制造商之一，年销售额超30亿元。公司拥有亚洲最大的蝶阀生产线，产品出口100多个国家。核心技术为衬胶蝶阀和双偏心密封结构，拥有发明专利10余项。品控理念为\"零缺陷，全球同质\"，所有产品通过ISO、API、CE认证。创始人刘国华从乡镇小厂起步，现已成为中国阀门行业领军人物。","product_intro":"该产品为船用衬胶蝶阀，适用于船舶冷却水系统、压载水系统、生活污水系统。核心卖点：阀体轻便（仅为闸阀的1/3）、衬胶层耐腐蚀、90度旋转快速启闭。适用于大口径管路（DN50~DN600），安装空间小。竞品优势：价格仅为进口蝶阀的1/2，且更换胶套成本低。相比球阀，蝶阀更适合大流量低压系统。","key_specs":{"材质":"球墨铸铁阀体+EPDM衬胶，耐海水腐蚀","公称压力":"1.0MPa，适用于低压系统","适用温度":"-10℃~80℃，适应常温海水","蝶板材质":"不锈钢（304），防锈耐磨","驱动方式":"手柄/蜗轮/气动可选，灵活适配"}}
