Belong to the thawing of the low-temperature metal between piece and lower sheet metal and push down lid door plate so as to discharge left snap arm and right snap arm, play isolation and make
With.
The beneficial effects of the utility model are：1 at the same using two transverse directions stopper arms come sealing cover door-plate, use
The strength locking lid door-plate of physical arrangement rather than spring, sealing effect are more than the three times of previous check-valves.2nd, it is logical to prolong plate after
It crosses several long handle handgrips that can rotate snapping to be fixed on housing, dismounting when being easily installed uses.3rd, hot melt piece uses
The mode of temporary weld with holes, the binding force of welding is strong, can sustain the power of two snap arm, and hot melting way is relatively steady
It is fixed.
