Description
Technical field
The utility model relates to a kind of manhole cover structure, relates in particular to a kind of manhole cover structure that is applied to liner jar case.
Background technology
For preventing that a jar case inside face is corroded, the jar case of transportation corrosive liquid all can paste line with rubber in one deck at the inside face of tank inner surface and manhole cover.As shown in Figure 1, it is the structural representation of a kind of arc manhole cover of the prior art, and this manhole cover comprises: manhole flange 1a, manhole cover flange 2a and sealing are connected the spherical cover plate 3a at manhole cover flange 2a intermediate openings place.Manhole flange 1a is welded on the tank body; Manhole cover flange 2a and manhole flange 1a when opening manhole, need turn on bolt through bolted connection; Remove manhole cover; So when line with rubber, manhole flange 1a and tank inner surface (not shown) are the one line with rubber, manhole cover flange 2a on the manhole cover and spherical cover plate 3a are the one line with rubber.Because the tank interior space is big; Do not have the dead angle, so the line with rubber of tank body and manhole flange inside face is relatively easy, and the line with rubber of manhole cover flange 2a and spherical cover plate 3a inside face needs to carry out line with rubber to spherical cover plate 3a inside face 31a through the bottom surface 21a of manhole cover flange 2a again to the inside face 21a of manhole cover flange 2a; But because the inside face 31a of the inside face 21a of manhole cover flange 2a and spherical cover plate 3a is too small at the angle of junction; Form the dead angle, so the line with rubber difficulty is big.
Another kind of arc manhole cover of the prior art; As shown in Figure 2; It comprises: the hinged seat 4c and that a curved cover plate 3c, is positioned at curved cover plate 3c outer rim one side is positioned at the handle 5c of curved cover plate 3c outer rim opposite side; Hinged seat 4c is hinged on the manhole neck (not shown) that links to each other with tank body, and curved cover plate 3c lower surface 31c is provided with a circle near the position ring of outer rim and is used for the groove 32c that is fastened togather with the manhole neck.During line with rubber, need the lower surface 31c one line with rubber to groove 32c and curved cover plate 3c, and space, groove 32c place is narrow and small, flex point is many, so, be difficult to line with rubber.
In order to solve the difficult problem of above-mentioned arc manhole cover line with rubber, existing liner jar case adopts flat manhole cover, and is as shown in Figure 3, because the lower surface 31b of flat manhole cover puts down, so be easy to line with rubber.And the compressive property of flat manhole cover is poor, in order to satisfy requirement of strength, must increase the thickness of slab of cover plate 3b, but can increase the weight of manhole cover so again, makes manhole cover feel effort and inconvenient in use.
Summary of the invention
