Abstract
The utility model relates to a kind of pressure container by manhole cover, comprise flange and be arranged on the cover plate on flange, the side of described flange is provided with the attaching parts for being fixedly connected with manhole, the thickness of attaching parts equals the wall thickness of vessel, described cover plate comprise with flange with the use of cover board body, the middle part outwardly convex of cover board body, the shape of bossing is circular, oval, butterfly or spherical.The utility model is advantageously: the utility model is convenient to welding in the process used, and under same pressure and temperature, cover plate of the present utility model can not thicken because of the increase of equipment operation pressure.
Description
Technical field
The utility model relates to bunkerage field, and particularly a kind of pressure container by manhole cover.
Background technology
Current existing pressure container, comprise vessel, vessel is cylindrical, and vessel is provided with manhole, and manhole is circular or oval, manhole is provided with flange, flange is provided with the blind flange for sealing manhole, and blind flange is a circular flat blind flange or reunion shape face-flange lid, and the blind flange of this structure is in the process used, can thicken along with the increase of equipment operation pressure, the thickness of blind flange also can increase along with the increase of manhole size in addition.In the process that flange welds with manhole, the bottom surface due to flange is a plane, so more difficult when welding with manhole.
Summary of the invention
For above-mentioned shortcoming, the utility model object is to provide a kind of pressure container by manhole cover.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pressure container by manhole cover, comprise flange and be arranged on the cover plate on flange, the side of described flange is provided with the attaching parts for being fixedly connected with manhole, the thickness of attaching parts equals the wall thickness of vessel, described cover plate comprise with flange with the use of cover board body, the middle part outwardly convex of cover board body, the shape of bossing is circular, oval, butterfly or spherical.
Described attaching parts and integrated flange are arranged, and the external diameter of the entrance point of attaching parts is greater than the external diameter of exit end, and the shape of attaching parts is identical with the shape of manhole.
The shape size of described bossing is identical with the shape size of manhole.
The utility model is compared with prior art advantageously: the utility model is convenient to welding in the process used, and under same pressure and temperature, cover plate of the present utility model can not thicken because of the increase of equipment operation pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of pressure container by manhole cover, the cover plate comprising flange 1 and be arranged on flange 1, the side of described flange 1 is provided with the attaching parts 3 for being fixedly connected with manhole, the thickness of attaching parts 3 equals the wall thickness of vessel, described cover plate comprise with flange 1 with the use of cover board body 2, the middle part outwardly convex 4 of cover board body 2, the shape of protruding 4 parts is circular, oval, butterfly or spherical.
Described attaching parts 3 and flange 1 integrated setting, the external diameter of the entrance point of attaching parts 3 is greater than the external diameter of exit end, the external diameter of attaching parts 3 entrance point is 50-100cm, and the external diameter of attaching parts 3 exit end is 10-40cm, and the shape of described attaching parts 3 is identical with the shape of manhole.
The shape size of described protruding 4 parts is identical with the shape size of manhole.
Attaching parts inserts in manhole and welds by the utility model in the process used, and welding is simple, convenient like this, and in order to convenient disassembly, can also add leader, handle can also be provided with Anti-slip cover in the part of cover board body projection; In order to ensure the tightness between cover plate and flange, a seal ring can also be added between cover plate and flange.
