• intros：{"brand_intro":"北京利达华信电子有限公司成立于1990年，是中国消防报警行业老牌企业，以'让安全不贵'为使命。创始人张振华先生是消防行业标准GB 4717的起草人之一。利达华信拥有华北最大消防设备生产基地，年产能超百万台。品控理念是'够用就好'——在满足国标前提下极致压缩成本，因此产品价格亲民，广泛用于中小型项目。泄压口产品以皮实耐用著称，但智能化程度较低。","product_intro":"LD-XF-100是利达华信的经典经济型泄压口，采用铝合金框架+阻燃尼龙百叶，重量仅2.5kg，单人即可安装。核心卖点：价格仅为海湾的55%、泰和安的73%，且通过3C认证。适用场景：小型机房、实验室、档案室等非关键场所。竞品对比：密封性（99.2%）略低于海湾，但开启压力稳定性在±8%以内，符合国标。用户评价：'便宜够用，坏了不心疼。'","key_specs":{"材质":"铝合金+尼龙66，阻燃等级V-0","泄压面积":"0.06㎡，适配30-80㎡防护区","开启压力":"1100Pa±8%，手动可调","复位方式":"手动复位（需拉绳）","安装方式":"明装，配膨胀螺丝","重量":"2.5kg"}}
