b.Opening and closing mechanism no. 6, open clamp no. 9 loose to the position;
c.Hold the handle no.10, put closure cover no.1 removed lightly, take out main sealing ring no.12;
d.Take off adjustable nut no.16, extract vertical shaft no. 17, lay front folder no. 14 and closure cover no 2 to safe place, and pay to protect sealing face.
e.Remove the front cover no. 8,top cover no.7 and guide screw no.5, take off clamp ring no.9 together with open &close mechanism no. 6 to safe place.
2.Barrel flange welding
Clean up the position between barrel flange no. 13 and barrel, make sure the inner bore alignment, according to folding location to find good direction: welding.
Usually, the material of Barrel flange designed according to the barrel material. Its welding property is same or equivalent to barrel material. If no special requirement, it is ok to use the barrel electrode to weld.
3.Heat treatment
After Barrel flange and barrel welded, Welding joint should be heat treatment for the whole or parts as to GB150-1998, it won’t affect the quality and property of barrel flange, but please pay to protect sealing face, avoid to collision and scratch.
4.check and inspection
After heat treatment of barrel flange and barrel, welding joint has to be 100% X ray examination, reaches II level is ok.
5.Assembly and adjustment
Clean up the sealing face of barrel flange and closure cover, to install the QOC as reversing disassembly order, adjust the folding mechanism to adjust bolt and nuts to make the closure cover to the central position of barrel flange, it is should coat antirust grease on connect thread, rotary parts and sealing face.
Usefulness
1. QOC’s opening
Open order: Twist off check screw no.2 to make the pressure falling to zero, then takes off interlocking board no 4, opening open & close mechanism (guide screw) no.6, loose clamp ring no.9 to open completely, hold handle no.10, make sure the closure cover opened completely, same time, put in or take out item from barrel.
