SFQM-1隧道防水板焊缝气密性试验仪 针式隧道防水板焊缝气密性试验仪 电动隧道防水板焊缝气密性检测仪
宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">一、概述:
宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">防水板接缝较多,放水的关键取决于接缝密封好坏程度。国家常采用的是双焊缝自动热合技术,这一种方法一方面能保证焊接质量,另一方面便于充气检查。

宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">充气检查方法是将5 mso-hansi-font-family:"Times New Roman"">号注射针与压力表相连接,用打气筒进行充气,当压力表达到0.25Mpa "Times New Roman";mso-hansi-font-family:"Times New Roman"">时停止充气,保持15min mso-hansi-font-family:"Times New Roman"">,压力下降在10% "Times New Roman"">以内,说明焊接缝合格。如压力下降过快说明有渗漏,用肥皂水涂在焊缝上,有气泡的地方重新补焊。
