3.3 The test fluid should be consistent with: the working liquid, the connection group is maintained, E10min, there should be no static leakage in the tight places; the head is maintained at a pressure of 30nin and there should be no leakage.
3.4 ​​During assembly, the sliding rod and the seat are matched, and there should be no leakage at the wide mouth after matching. 3.5 To facilitate the installation of the pipe head, it is recommended to provide a close flange LN10 (JB/2U1.14.2 or JE/T 2001.15.1) on the 22×6mm pipe.
