It seals between plain cushion and the side wall of the ream platform.
In this manner it is ensured that sealing effect during internal boost process mesolow.
Further, the head cover is towards having circumferentially arranged groove at the outer ledge of the side of the manhole,
The secondary sealing area is the bottom surface of the groove；The inner shape of the groove is consistent with the shape of the manhole.
In this way, due to having groove at the outer ledge of head cover so that the middle part of head cover forms protrusion, convenient for sealing plain cushion
Positioning, it is convenient for assembly.
Further, the positioning plate is annular in shape, and has boss, the shape of the boss towards the side of the manhole
It is consistent with the shape of the manhole.
Using the above structure, by positioning plate setting circlewise, it can facilitate and top plate is operated, meanwhile, in positioning plate
Upper setting boss can limit positioning plate and be moved horizontally on manhole, be fastened convenient for subsequent bolt, reduce installation difficulty.
Further, the side of the head cover towards the manhole is also equipped with hanging ring.
In this way, head cover can be pressed on the inside of manhole using hanging ring, facilitates installation before bolt fastening.
Further, it is also associated with iron chains between head cover side inwardly and the inner wall of the tank body.
In this way, by after disassembling bolts, head cover can be hung in by iron chains in tank body, prevent head cover from falling to tank base,
Facilitate subsequent installation.
Further, the manhole is ellipse or oblong.
In this way, head cover can be facilitated to be packed into tank body outside tank body.
In conclusion the utility model have it is reasonable in design, difficulty of processing is smaller, easy for installation, sealing performance compared with
Well, the advantages that relatively low to the intensity requirement of bolt.
