After placed , the connection box should repeat above testing immediately
Test procedure as following :
First , use the shortest Length 38mm,Diameter 6.4mm flat-head circular shaft against knock-off cover apply 44.5N force,continue apply force 1min
Apply force direction with orifice cove plane vertical , its add maybe cause knock-off orifice cover move place , after 1 h , measurement orifice cover with connection box wall dislocation
Second , use a screw knife as chisel , Open the knock-off cover , knockoff after allow the screw knife blade edge along already opened inner wall scratch a circle. In order to clear the edge’s debris
Third , For another two knock-off cover repeat the first step and second step
If connection box’s knock-off cover can have more diameter trepan , when small diameter knock off cover is opened , big diameter knock-off cove should not move , qualified determination
