题目内容
案例分析题某机电设备安装公司承担了理工大学建筑面积为2万平方米的图书馆工程的通风空调系统施工任务。该工程共有S1～S6六个集中式全空气空调系统，空调风系统设计工作压力为600Pa。空气处理机组均采用带送风机段的组合式空调机，由安装公司采购并组成项目部承担安装任务。风管系统安装完毕后，严密性试验采用漏光法检测合格。当施工进入空调系统调试阶段时，系统出现三个问题：①空气处理机组运转时晃动；②S1系统调试中在风管所有阀门全开情况下，实测送入空调区风量小于设计风量且相差较大，而该系统风机出口风量实测值符合设计要求；③空气处理机组冷却水进出管路上的阀门有滴水，经检查这两个阀门未保冷但无漏水。针对上述问题，施工单位采取了整改措施后才使系统调试合格。空调系统调试完成后，按施工质量验收程序进行了施工质量验收工作。问题 解决阀门滴水问题的措施有哪些？
