Abstract
The utility model relates to an optimized air-storage tank inspection-hole structure, which comprises a manhole ring, a nut, a gasket, a pressure plate, a cover plate, a bolt and a sealing ring, wherein the cover plate is elliptic, the radial section of the manhole ring is elliptic, the cover plate is covered on the inner end surface of the manhole ring, the sealing ring is arranged between the cover plate and the inner end surface of the manhole ring, the bolt is fixedly arranged on the cover plate, the nut and the gasket are both arranged on the bolt, the pressure plate is positioned between the gasket and the outer end surface of the manhole ring, the manhole ring is formed from a seamless steel pipe with an elliptic radial section, more than three positioning parts are fixedly arranged in the inner-end inner wall of the manhole ring along the circumferential direction, and the sealing ring is positioned between the positioning parts and the cover plate. The utility model solves the quality problem caused by welds by forming the manhole ring through the seamless steel pipe, eliminates the quality hidden danger invisible to naked eyes, saves the man hour and the material consumed by manual electric-arc welding, prevents the sealing ring from sliding out when in installation by arranging the positioning parts in the manhole ring, lowers the installation difficulty and ensures the installation quality.
Description
Technical field:
The utility model relates to container, relates in particular to gas holder, the particularly peep hole of gas holder, and concrete is a kind of gas holder peep hole structure of optimization.
Background technique:
Peep hole on the gas holder is also referred to as manhole, under the normal working of container, it is by covering palte seal, when needs annual test or third pary certification or discovery have other situation, need open cover plate, the work maintainer enters container intracavity by peep hole and is engaged in the inspection operation.In the prior art, peep hole is made of manhole circle, nut, packing ring, pressing plate, cover plate, bolt and seal ring, and it is oval that cover plate is, and the manhole circle is radial cross section and is oval tubular, by two radial cross sections is that semielliptical workpiece welding constitutes, because its weld seam can't be done the RT non-destructive inspection, therefore can not guarantee the weld seam inherent quality, often produce the phenomenon of infiltration in use, simultaneously, welding two semiellipse workpiece needs manual finishing, and efficient is low, the cost height.In addition, when cover plate was packed in the manhole circle, seal ring often can not put in place, caused sealing surface to reveal.
Summary of the invention:
The purpose of this utility model is to provide a kind of gas holder peep hole structure of optimization, and the gas holder peep hole structure of described this a kind of optimization will solve the technical problem that manhole circle weldquality can not guarantee, manhole circle welding efficiency is low, cost is high and seal ring can not put in place in the gas holder peep hole device in the prior art.
The gas holder peep hole structure of this optimization of the present utility model is by the manhole circle, nut, packing ring, pressing plate, cover plate, bolt and seal ring constitute, it is oval that described cover plate is, it is oval that the radial cross section of described manhole circle is, cover plate covers and is arranged on the interior edge face of manhole circle, described seal ring is arranged between the interior edge face of cover plate and manhole circle, described bolt setting on the cover board, described nuts and washers all is arranged on the bolt, described pressing plate is between packing ring and manhole circle exterior edge face, wherein, described manhole circle is oval seamless steel pipe by a radial cross section and constitutes, along the locating piece that circumferentially is set with three above numbers, described seal ring is between locating piece and cover plate in the inner inwall of manhole circle.
Further, the edge circumferentially is set with four locating pieces in the inner inwall of manhole circle.
Working principle of the present utility model is: the manhole circle is oval seamless steel pipe by radial cross section and constitutes, and has solved because the quality problems that weld seam causes have been eliminated the hidden danger of quality that is invisible to the naked eye, and saved man-hour that manual electric arc welding consumed and material.Locating piece prevents that seal ring from skidding off when mounted, has reduced installation difficulty, has guaranteed installation quality.
The utility model compared with the prior art, its effect is actively and significantly.The utility model utilizes seamless steel pipe to constitute the manhole circle, solved because the quality problems that weld seam causes, eliminated the hidden danger of quality that is invisible to the naked eye, and man-hour that manual electric arc welding consumed and material have been saved, in the manhole circle, locating piece is set, prevented that seal ring from skidding off when mounted, reduced installation difficulty, guaranteed installation quality.
Description of drawings:
Fig. 1 is the structural representation of the gas holder peep hole structure of a kind of optimization of the present utility model.
Embodiment:
As shown in Figure 1, the gas holder peep hole structure of a kind of optimization of the present utility model, by manhole circle 4, nut 8, packing ring 7, pressing plate 6, cover plate 1, bolt 5 and seal ring 2 constitute, it is oval that described cover plate 1 is, it is oval that the radial cross section of described manhole circle 4 is, cover plate 1 covers and is arranged on the interior edge face of manhole circle 4, described seal ring 2 is arranged between the interior edge face of cover plate 1 and manhole circle 4, described bolt 5 is fixedly installed on the cover plate 1, described nut 8 and packing ring 7 all are arranged on the bolt 5, described pressing plate 6 is between packing ring 7 and manhole circle 4 exterior edge faces, wherein, described manhole circle 4 is oval seamless steel pipe by a radial cross section and constitutes, and along the locating piece 3 that circumferentially is set with three above numbers, described seal ring 2 is between locating piece 3 and cover plate 1 in the inner inwall of manhole circle 4.
Further, the edge circumferentially is set with four locating pieces 3 in the inner inwall of manhole circle 4.
The working procedure of present embodiment is: manhole circle 4 is oval seamless steel pipe by radial cross section and constitutes, and has solved because the quality problems that weld seam causes have been eliminated the hidden danger of quality that is invisible to the naked eye, and saved man-hour that manual electric arc welding consumed and material.Locating piece 3 prevents that seal ring 2 from skidding off when mounted, has reduced installation difficulty, has guaranteed installation quality.
