Abstract
A manhole device used for a spherical tank comprises a manhole flange, lower paired manhole flanges, upper paired manhole flanges, an ellipsoidal head and a connection pipe with a flange. The manhole flange is arranged on the manhole edge of the spherical tank, and the lower paired manhole flanges and the manhole flange are fixedly welded. The upper paired manhole flanges and the ellipsoidal head are fixedly welded. The connection pipe with the flange is communicated with a cavity inside the ellipsoidal head through a hole in the ellipsoidal head and welded to the outer wall of the ellipsoidal head. The lower paired manhole flanges and the upper paired manhole flanges are connected and fixed through fixing pieces. The manhole device has the advantages that the weight is light, the structure is reasonable, and a manhole is combined with a discharge pipe (bottom) or a bleeder (top), so that the hole-forming area of a spherical tank case is reduced.

In prior art, manhole device is heavier, and on its spherical tank housing, manhole, drain pipe (bottom), exhaust stack (top) point are arranged, and have increased the perforated area on spherical tank housing, has increased the potential safety hazard during spherical tank uses.
Summary of the invention
For solving the problems of the technologies described above, technical problem to be solved in the utility model is to provide a kind of spherical tank manhole device, and it can solve the problem that existing manhole device's consumptive material is many, structure is heavy; And manhole and drain pipe (bottom) or exhaust stack (top) are merged, reduce the perforated area on spherical tank housing.
The technical solution of the utility model is: a kind of manhole device for spherical storage tank, and manhole device comprises manhole flange, pairing manhole lower flange, pairing manhole upper flange, ellipsoidal head, flanged adapter;
Manhole flange is located at spherical storage tank people bore edges, the fixing welding of pairing manhole lower flange and manhole flange;
The fixing welding of pairing manhole upper flange and ellipsoidal head, flanged adapter is communicated with by the Kong Yuqi internal cavities on ellipsoidal head, and flanged adapter is welded on ellipsoidal head outer wall;
Pairing manhole lower flange is connected and fixed by fixed block with pairing manhole upper flange.
In the utility model embodiment, preferably, the extremely middle plate butt welding of manhole flange and spherical tank housing is welded.
Preferred in the utility model embodiment, fixed block comprises bolt, nut, gasket seal, bolt is fixed through the hole on pairing manhole lower flange, pairing manhole upper flange and with nut, gasket seal is enclosed within on bolt, is located between pairing manhole lower flange and/or pairing manhole upper flange and nut.
In the utility model embodiment, preferably, ellipsoidal head outer wall is provided with handle.
Further, the height of flanged adapter is 180~200mm.
All right, flanged nozzle inner wall is provided with annular fixed hole.Preferred in the utility model embodiment.
Compared with prior art, its useful effect is the utility model:
1, replace traditional dull and stereotyped manhole cover (end socket) with ellipsoidal head, bearing capacity strengthens, and under same pressure working condition, adopts ellipsoidal head can greatly reduce material consumption, and alleviator weight, reduces work load.
2, on ellipsoidal head, directly offer flanged adapter, can be set to exhaust stack or drain pipe, cancelled the directly perforated area on spherical tank housing of exhaust stack and drain pipe.
Brief description of the drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representation.
In figure: the extremely middle plate 1 of spherical tank housing, manhole flange 2, pairing manhole lower flange 3, pairing manhole upper flange 4, ellipsoidal head 5, handle 6, flanged adapter 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
