Abstract
The utility model discloses an upper end cover for a heat preservation water tank, which comprises an arc-shaped bottom surface (1) and an annular side wall (2), wherein a manhole (3) is arranged at the center of the arc-shaped bottom surface (1), a transitional circular arc (5) is arranged between the arc-shaped bottom surface (1) and the annular side wall (2), and central axes of the annular side wall (2) and the arc-shaped bottom surface (1) are parallel to each other. In actual use, the upper end cover for the heat preservation water tank can be easily and closely matched with a barrel body of the water tank, thus ensuring heat preservation effect.
Description
Technical field
The utility model relates to a kind of upper end cover, particularly a kind of attemperater upper end cover.
Background technology
Attemperater also is the insulation water tower, and it generally is made up of the water tank ladle body of loam cake end and straight-tube shape.Present existing loam cake end is combined by arcuation bottom surface and annular sidewall as shown in Figure 1, and the center position in the arcuation bottom surface is provided with access opening; According to the difference that rigidity requires, the loam cake end that has is provided with reinforced rib on the arcuation bottom surface, and the loam cake end that has then is not provided with reinforced rib.For the ease of with the loam cake end cap on the water tank ladle body, so annular sidewall is designed to outward-dipping slightly from top to bottom.This structure causes the cooperation that loam cake end and water tank ladle body can't be tight, thereby causes heat insulation effect poor.
The utility model content
Thereby the technical problems to be solved in the utility model provides and a kind ofly can tightly cooperate the attemperater upper end cover of guaranteeing heat insulation effect with the water tank ladle body easily.
In order to solve the problems of the technologies described above, the utility model provides a kind of attemperater upper end cover, comprises arcuation bottom surface and annular sidewall, and the center position in the arcuation bottom surface is provided with access opening; Between arcuation bottom surface and annular sidewall transition arc is set, annular sidewall parallels with the central axis of arcuation bottom surface.
Improvement as attemperater upper end cover of the present utility model: the radius of transition arc is 3～10mm.
Further improvement as attemperater upper end cover of the present utility model: the outside face at annular sidewall is provided with the gear-like protuberance.
Further improvement as attemperater upper end cover of the present utility model: the arcuation bottom surface is provided with reinforced rib.
Attemperater upper end cover of the present utility model, owing between arcuation bottom surface and annular sidewall, be provided with transition arc, therefore the internal diameter of annular sidewall can be arranged to external diameter in actual the use with the water tank ladle body, and can guarantee that annular sidewall is vertical, that is, guaranteed the parallel central axis with the arcuation bottom surface of annular sidewall.During actual like this use, because slight elastic deformation can take place transition arc, therefore when the annular sidewall of attemperater upper end cover contacted with the water tank ladle body, temporarily being deformed into that annular sidewall can be slight was outward-dipping slightly from top to bottom; Thereby guarantee that the attemperater upper end cover can be sleeved on the water tank ladle body easily.After whole suit action was finished, annular sidewall reverted to the plumbness of itself naturally, thereby made the inwall of annular sidewall and the outside face of water tank ladle body realize sealing contact, thereby improved the heat insulation effect of whole attemperater.
The reinforced rib that is provided with on the arcuation bottom surface can improve the intensity of arcuation bottom surface, can improve the intensity of annular sidewall at the gear-like protuberance of the outside face setting of annular sidewall; Above-mentioned 2 binding energy improves the bulk strength of attemperater upper end cover.The gear-like protuberance also has the effect that beautifies whole attemperater upper end cover.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the sectional structure scheme drawing as the loam cake end of prior art;
Fig. 2 is the main TV structure scheme drawing of attemperater upper end cover of the present utility model;
Fig. 3 is the sectional structure scheme drawing of Fig. 2.
The specific embodiment
Fig. 2 and Fig. 3 are in conjunction with having provided a kind of attemperater upper end cover, comprise arcuation bottom surface 1 and annular sidewall 2, center position in arcuation bottom surface 1 is provided with access opening 3, and (diameter of access opening 3 is generally 400～500mm), also is provided with some the reinforced ribs that are parallel to each other 4 (being shown as 3 among Fig. 2 and Fig. 3) on arcuation bottom surface 2.Between arcuation bottom surface 1 and annular sidewall 2 transition arc 5 is set, the radius of this transition arc 5 is 3～10mm.Annular sidewall 2 is a vertical configuration, that is, annular sidewall 2 parallels with the central axis 11 of arcuation bottom surface 1.Outside face at annular sidewall 2 is provided with gear-like protuberance 6, and the height of gear-like protuberance 6 is generally 5～50cm.In actual the use, the internal diameter of annular sidewall 2 can be arranged to external diameter with the water tank ladle body.
During the actual use of this attemperater upper end cover, it is sleeved on the water tank ladle body.Because slight elastic deformation can take place transition arc 5, therefore when annular sidewall 2 contacted with the water tank ladle body, temporarily being deformed into that annular sidewall 2 can be slight was outward-dipping slightly from top to bottom; Thereby guarantee that the attemperater upper end cover can be sleeved on the water tank ladle body easily.After whole suit action was finished, annular sidewall 2 reverted to the plumbness of itself naturally, thereby made the inwall of annular sidewall 2 and the outside face of water tank ladle body realize sealing contact, thereby improved the heat insulation effect of whole attemperater.The mode of available rivet or welding realizes being fixedly linked of annular sidewall 2 and water tank ladle body.During actual the use, access opening 3 is in blocked state; Only when maintenance, access opening 3 just is in open state.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
