Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a flat welding flange with a neck, please refer to fig. 1 to 4, a movable block 7 is connected with a flange neck 2 in a sliding manner, the movable block 7 can slide left and right and can drive a limiting rod 5 at the end part to slide, a mounting inclined block 6 is arranged on a flange plate, the inclined plane of the mounting inclined block is matched with the inclined plane on the movable block 7, when the flange neck 2 and the flange plate 1 are mounted, a protruding end 401 is arranged in a through hole 3, the through hole 3 and a small through hole 4 are ensured to be right opposite, and in the mounting process, the mounting inclined block 6 can push the movable block 7 to slide outwards, so that the limiting rod 5 is pushed into a clamping groove 9, the limiting rod 5 enters the clamping groove 9 to be clamped, thereby limiting the rotation of the flange neck 2 and realizing the primary fixing of the flange neck 2, therefore, the flange neck 2 cannot rotate during welding, the welding quality is improved, and the diameter of an annular groove 8 is larger than the diameter of the large end of the circular table-shaped flange neck 2, so the installer can observe whether the limiting rod 5 completely extends out and is clamped into the clamping groove 9, if the limiting rod 5 does not completely extend into the clamping groove 9, the flange neck 2 at the position is not completely attached to the flange plate, the installer can be helped to conveniently judge whether the flange neck 2 has height deviation after installation, and the exposed ring groove can be used as a welded seam groove, so that the installer can conveniently perform welding operation.
Further, the flange neck 2 is set to be the round platform shape, and structural strength is increased, and service life is prolonged, and still be provided with the packing ring 11 on the ring flange 1, packing ring 11 protrusion ring flange 1's plane, when connecting two flanges, the bolt passes from bolt hole 10, can give packing ring 11 bigger pressure when screwing the bolt, reinforcing sealing performance.
When the flange neck 2 and the flange plate 1 are welded, the movable block 7, the limiting rod 5 on the movable block, the mounting inclined block 6 and the clamping groove 9 are matched with each other to lock the rotation of the flange neck 2, whether the height deviation exists or not can be distinguished through the extending length of the limiting rod 5 and the matching tightness degree of the clamping groove 9, and the problem that the welding quality does not reach the standard and further the flange quality is influenced due to the fact that the flange neck 2 is staggered in the welding process is effectively solved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the design concept of the present invention should be included in the scope of the present invention.
