mso-hansi-font-family:"Times New Roman"">一、产品标准依据

mso-hansi-font-family:"Times New Roman"">沧州中亚试验仪器有限公司生产的金属导管量规符合《GB20041电气安装用导管系统通用要求》、《GBT 17194-1997 电气导管 "Times New Roman"">电气安装用导管的外径和导管与配件的螺纹》。

mso-hansi-font-family:"Times New Roman"">二、金属导管量规选择方法:

1、测量导管最大外径:GBT17194-2导管最大外径的环规

2、测量导管最小外径:GBT17194-3a/3b(刚性/ mso-hansi-font-family:"Times New Roman"">非刚性)

3、测量导管外螺纹:GBT17194-4外螺纹通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">环规

4、测量导管内螺纹:GBT17194-5内螺纹通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">塞规

5GBT17194-5内螺纹通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">塞规:68 mso-hansi-font-family:"Times New Roman"">、10 "Times New Roman"">、1216 mso-hansi-font-family:"Times New Roman"">、20 "Times New Roman"">、2532 mso-hansi-font-family:"Times New Roman"">、40 "Times New Roman"">、5063 mso-hansi-font-family:"Times New Roman"">、75 "Times New Roman"">,共12

mso-hansi-font-family:"Times New Roman"">四、金属导管量规使用方法:

1、检测导管最大外径:试样长度依据标准要求,选择《GBT17194-2导管最大外径的环规》无需过分用力便能使环规通过整段导管试样时,该导管试样为合格。正常情况下,有保护性涂镀层的导管应在涂镀前进行此项试验。

2、检测金属刚性导管最小外径:试样长度依据标准要求,选择《GBT17194-3a刚性金属导管最小外径量规》不过分用力,量规就不可能通过整段导管时,该导管试样为合格。

3、检测非金属刚性导管最小外径:试样长度依据标准要求,选择《GBT17194-3b非刚性金属导管最小外径量规》在自重作用下,环规不能通过整段导管时,该导管试样为合格。

4、检测导管与配件的外螺纹:试样长度依据标准要求,选择《GBT17194-4外螺纹通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">环规》,无需过分用力便可把螺纹环规(T) "Times New Roman"">旋入导管的螺纹中;而不过分用力,就无法使螺纹环规(Z) "Times New Roman"">通过螺纹,则该导管试样的外螺纹为合格。

5、检测导管与配件的内螺纹:试样长度依据标准要求,选择《GBT17194-5内螺纹通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">塞规》,无需过分用力便可把螺纹塞规(T) "Times New Roman"">旋入导管的螺纹中去;而不过分用力就无法使螺纹塞规(Z) "Times New Roman"">通过螺纹,该配件试样的内螺纹为合格。
