2. the seal arrangement with convenient handling lid of the utility model adopts stainless steel rectangular iron hoop to reinforce casing, and rectangle iron hoop frame is lived arm of angle circle that four side plates of casing connect, the distortion can reduce casing and do filling water test time; The supporting bracket that in casing, arrangement can conveniently be taken out and put into, the collapse defect that can prevent from vacuumizing time, lid strength deficiency causes;

3. the seal arrangement with convenient handling lid of the utility model adopts detachable vacuum chuck structure to connect the aperture on lid, while vacuumizing, the rubber of sucker can tightly be fitted in smooth plexiglass surface, both can connect external equipment by sucker inipple, or seal, easy to connect, sealing is reliable, is conducive to the test vacuumizing under repeated disassembled and assembled lid condition.

The technical characteristics of the seal arrangement with convenient handling lid below in conjunction with drawings and Examples to the utility model is further described.
