• intros：{"brand_intro":"泰科（Tyco）是全球消防与安防巨头，隶属于江森自控（Johnson Controls），品牌历史可追溯至1960年。其末端试水装置以军工级精工著称，核心优势在于阀芯采用316不锈钢和PTFE密封圈，耐高压（2.5MPa）且零泄漏。泰科品控遵循UL和FM双认证标准，每台设备出厂前经过100次循环测试。虽然价格是国产品牌的2-3倍，但在高端商业地产、数据中心、机场等场景中占据主导地位，被誉为\"消防界的劳斯莱斯\"。","product_intro":"TYCO-DN20末端试水装置专为高压喷淋系统设计，支持DN20（3/4英寸）接口，最大工作压力2.5MPa。核心卖点：全金属结构无塑料件、压力表带防震填充液、手柄带扭矩限制器（防止过拧损坏）。对比海湾产品，泰科在极端环境（如化工厂、冷库）下密封性更优，但价格翻倍。适用场景：超高层建筑、精密仪器车间、核电站等对可靠性要求极高的场所。","key_specs":{"公称直径":"DN20（3/4英寸，适配细管径系统）","阀体材质":"316不锈钢（耐酸碱腐蚀，寿命20年）","压力表量程":"0-2.5MPa（充油防震，精度1.0级）","工作温度":"-40℃~120℃（适应极端工业环境）","连接方式":"外螺纹（NPT标准，美标接口）","适用标准":"UL 2600 / FM 1120（国际双认证）"}}
