Detailed Description

The present invention will now be described in further detail with reference to the attached drawings, which are provided for purposes of illustration and not limitation.

As shown in fig. 1, 2 and 3, the present invention relates to a connecting structure for corrosion-resistant pipelines, which comprises an upper fastening device and a lower fastening base. The upper fixing device and the lower fixing base are a whole set of components. The use of the assembly is programmatically comparable to the manner of welding, without the need for welding. Compared with a socket type connecting piece, the socket type connecting piece is labor-saving and high in fastening degree.

The upper fastening device comprises a threaded column 3, wherein the threaded column 3 is sleeved with a force bearing part 4, and the left side and the right side of the force bearing part 4 are fixedly connected with a left fin 41 and a right fin 42. The left fin 41 and the left threaded rod 5 are screwed. The right fin 42 and the right threaded rod 51 are threadedly connected. The middle part of the threaded rod 51 is provided with threads, the two ends of the threaded rod are clamped in the clamping grooves of the clamping columns, and the parts clamped in the clamping grooves are not provided with threads. Bearing part 4 is through the fin and the cooperation of screw thread stick cooperation and other parts of controlling both ends, and the area of fastening is bigger, and the effect of fastening is better, and two-way bearing moreover, bearing force is higher, and the fastening effect is better.

Lower unable adjustment base includes arc bottom plate 8, and first calorie of post 6, second card post 61, third card post 62 and fourth card post 63 of fixed connection are all around to 8 upper surfaces of arc bottom plate. The middle part of the arc-shaped bottom plate 8 is fixedly connected with an internal threaded pipe 81. The threaded post 3 is screwed into the internally threaded tube 81. The both ends of left-hand thread stick 5 inlay respectively in first calorie of post 6 and fourth calorie of post 63 top, and right-hand thread stick 51 inlays respectively in second calorie of post 61 and third calorie of post 62 top. The arc bottom plate 8 enables the connecting piece and the pipe wall to have the same radian, the matching degree and the sealing degree are higher. The four clamping columns are distributed on the periphery of the connecting piece and are matched with the upper fastening device, so that the strength is better. The threaded rod is matched with the top end of the clamping column, so that the fastening area of the connecting piece is increased. In practice, holes for the clamping posts are first provided at the pipeline connection by means of a drill or other cutting device on both sides of the connection.

The top end of the threaded column 3 is an 8-edge column nut. The force bearing part 4 is sleeved between the screw cap and the screw rod of the threaded column 3. When the threaded post 3 is rotationally tightened and loosened. The force bearing part 4 does not rotate along with the threaded column 3. The bearing part 4 is sleeved on the threaded column in the processing link, and then the threaded column 3 is subjected to thread processing. The advantage of this structure lies in that load-bearing member 4 does not rotate along with the screw post when screw post 3 rotates to screw up, and load-bearing member 4 only overlaps on screw post 3, does not connect with screw post 3. The function of the nut is to press the bearing part 4 to fasten the whole connecting part.

As shown in fig. 2, long cylinders are fixedly welded inside the left end and the right end of the force bearing part 4, the middle part of the long cylinder on the right side and the right fin 42 are integrally cast, and the long cylinder on the left side and the left fin 41 are integrally cast. The left side and the right side of the force bearing part 4 are provided with grooves during processing, and then wings cast integrally are welded in the grooves. The left fin 41 and the right fin 42 are arc-shaped, and have screw holes on the outer sides. The left end and the right end of the bearing part 4 are provided with a left groove and a right groove, the left groove is internally welded with a left cylinder 43 of the left fin 41, and the right groove is internally welded with a right cylinder 44. The left threaded hole 411 is connected to the outer side of the left fin 41, and the right threaded hole 421 is connected to the right end of the right fin 42.

Install left backing plate 7 and right backing plate 71 between first card post 6, second card post 61, third card post 62 and fourth card post 63 and the pipe wall 1, left side backing plate 7 and right backing plate 71 are bent shape, laminate in pipe wall 1. The base plate has the effects that the clamping column of the lower fixing base is not directly contacted with the pipe wall, and the joint is completely sealed by the base plate, the filled anticorrosive material and the later sprayed anticorrosive layer; and meanwhile, the corrosion prevention effect is better, and the clamping column is not contacted with a petroleum product, so that the clamping column is prevented from being corroded to the greatest extent to cause the failure of the connecting piece.

And anticorrosive materials are filled between the arc-shaped bottom plate 8 and the left and right backing plates 7 and 71. Anticorrosive material fills in all space positions of junction, solidifies through anticorrosive glue simultaneously, forms complete sealing state, has certain toughness simultaneously, and backing plate and bottom plate are the same material.

The bottom surface and the end surfaces at two ends of the arc-shaped bottom plate 8 are coated with the anticorrosive coatings 2. The inner surface of the pipe wall 1 is coated with an anticorrosive coating 2. The outer side surfaces of the left pad 7 and the right pad 71 are also coated with the anticorrosive layer 2. The anticorrosive coating 2 of pipe wall 1 is predetermine earlier stage, and the anticorrosive coating 2 of the arc bottom plate 8 of backing plate sprays when installing.

The utility model discloses when implementing, unable adjustment base and backing plate under earlier the pipeline installation to one side, then go on filling anticorrosive material to all spaces departments, solidify with anticorrosive gel, then spout anticorrosive coating 2. After one side is installed, the pipe wall 1 at the other side of the joint is sleeved on the lower fixing base to be piled up and debugged, then the upper fixing device is installed, when the upper fixing device is installed, the positions of the left and right fins are also adjusted along with the fastening of the threaded columns 3, and the threaded rods are installed when the threaded holes of the left and right fins are symmetrically arranged between the clamping grooves of the left or right clamping columns. When the threaded rod is installed, the threaded column 3 is continuously lifted, and the two wings bear the stress of the whole connecting mechanism, so that the two connecting pipelines are tightly connected together. And then spraying anticorrosive gel on the outside to solidify and enhance the sealing property of the whole connecting piece.

The embodiments given above are preferred examples for implementing the present invention, and the present invention is not limited to the above-described embodiments. Any non-essential addition and replacement made by the technical features of the technical solution of the present invention by those skilled in the art all belong to the protection scope of the present invention.
