Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the gate of a flaw detection room, and more specifically, to an opening-and-closing type sealed gate. Background Art
[0002] There are several types of gates for flaw detection rooms. Different radiation sources have different requirements for the corresponding gates. Some gates have lead plates hung on the door bodies for shielding, and some are concrete doors. With the continuous development of technology, the trend of equipment large-scale has gradually emerged. Larger ships, or larger boilers, etc. Larger and larger large welded structural parts need to be flaw detected. Therefore, the volume requirement of the flaw detection room is also getting larger and larger. Correspondingly, the size of the portal is larger. The concrete-cast gate of the flaw detection room is more common in the field of large-scale industrial flaw detection because of its convenient construction, ability to absorb rays and scattered rays, low protection cost and good effect. When the size of the door body increases and the self-weight of the gate reaches several thousand tons, higher requirements are placed on safety and maintainability.
[0003] The existing forms of the gates of flaw detection rooms are relatively large in size. When in use, since there are rays inside the flaw detection room, poor sealing of the gate will cause the rays to diffuse outward, causing harm to the personnel in the external environment. Content of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, the utility model provides an opening-and-closing type sealed gate, which has the advantages of being easy to manufacture and having good sealing performance.
[0005] To achieve the above object, the utility model provides the following technical solution: An opening-and-closing type sealed gate, comprising: a gate body, a lapping area and a sealing structure. The gate body is integrally square in structure and is arranged in an opening-and-closing manner; the gate body stands upright outside the wall with a tiny gap left. There is a door opening in the wall. The size of the gate body is larger than the size of the door opening. Lapping areas are left on the outer side and the top of the gate body; a sealing structure is arranged at the mutually contacting part of the gate bodies; a door groove is opened on the ground at the lower part of the gate body. The door groove is a rectangular groove, and the gate body moves along the door groove outside the wall.
[0006] As a preferred technical solution of the utility model, the lapping area is always located in the area outside the door opening of the gate.
[0007] As a preferred technical solution of the utility model, the sealing structure is integrally in a "Z" shape and is composed of a first sealing surface and a second sealing surface. The second sealing surface is inclined, the first sealing surface is vertical, and the first sealing surface is on both sides of the second sealing surface; the inclination angle of the second sealing surface is 40° - 50°; the first sealing surfaces of the gate bodies are mutually contacted, and the second sealing surfaces are mutually contacted. Rubber plates are arranged on the contacting surfaces.
[0008] As a preferred technical solution of the present utility model, a convex door frame is provided on the wall on the side of the door body of the large door facing the flaw detection room, and the convex door frame is integrally in an L-shaped structure.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The overlapping area of the door body of the present utility model can meet the gap control amount required for protection, which is convenient for manufacturing and can prevent the refraction of rays. By providing a Z-shaped sealing structure and using the mutual closing of the sealing surfaces to improve the sealing performance, the outward scattering of rays can be avoided.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0015] As Figures 1 to 3 shown, the present utility model provides a pair-opening sealed large door, including: a large door body 1, an overlapping area 3, and a sealing structure 4. The large door body 1 is integrally in a square structure, and the large door body 1 is arranged in a pair-opening manner; the large door body 1 stands upright on the outside of the wall 2, and a door opening is provided in the wall 2. The size of the large door body 1 is larger than the size of the door opening. An overlapping area 3 is left on the outside and the top of the large door body 1; a sealing structure 4 is provided at the part where the large door bodies 1 are in contact with each other; a door groove 5 is opened on the ground at the lower part of the large door body 1, and the door groove 5 is a rectangular groove, and the large door body 1 moves along the door groove 5 on the outside of the wall.
[0016] Among them, the overlapping area 3 is always located in the area outside the door opening of the wall 2. The setting of the overlapping area 3 can correspond to the outer dimension of the door body being larger than the door opening dimension after closing the door. The overlapping area 3 can meet the gap control amount required for protection, which is convenient for manufacturing and can prevent the refraction of rays.
[0017] Among them, the sealing structure 4 is integrally in a "Z" shape and is composed of a first sealing surface 7 and a second sealing surface 8. The second sealing surface 8 is inclined, the first sealing surface 7 is vertically arranged, and the first sealing surface 7 is on both sides of the second sealing surface 8; the inclination angle of the second sealing surface 8 is 40° to 50°; the first sealing surfaces 7 of the large door body 1 are mutually attached, and the second sealing surfaces 8 are mutually attached, and rubber plates are arranged on the attachment surfaces.
[0018] Among them, a convex door frame 6 is arranged on the wall of the large door body 1 facing the flaw detection room, and the convex door frame 6 is integrally in an L shape. During construction, only the flatness of the door frame needs to be controlled for the convex door frame 6 to ensure that the gap requirements are met, and there is no requirement for the high flatness of the entire wall. It has good economy and is convenient to control the small gap between the large door and the wall.
