Description
Technical Field
The utility model relates to a pipeline transformation technical field, in particular to integrated structure is taken over to inside lining pipeline.
Background
In a wet flue gas desulfurization system, the concentration of desulfurized wastewater slurry C L-is high, the pH value is generally between 5 and 5.5, and the desulfurized wastewater slurry is corrosive.
For some reconstruction projects, the carbon steel rubber-lined (plastic) pipelines are required to be connected with pipes, and the pipe diameters of the pipes are small and are generally below DN 50. At present, carbon steel rubber-lined (plastic) pipelines, particularly circulating slurry pipelines (generally more among DN 450-1100), can only be completely removed and returned to a factory, perforated and re-lined with rubber and then installed, and the problems of long construction period, high construction difficulty and high cost exist.
Therefore, a new external connection tube structure needs to be developed, which can not only realize the function of online connection tube, but also ensure the sealing performance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lining pipeline takeover integral structure.
The technical scheme of the utility model: the utility model provides an integrated structure is taken over to inside lining pipeline, includes sets up mounting hole, nozzle seat and the clamp plate that runs through on original pipeline, be equipped with sealed face on the nozzle seat, when the nozzle seat inserts the mounting hole after changeing just, sealed face all around just with the interior laminating of following of mounting hole, the clamp plate is located the lateral wall of original pipeline, clamp plate and nozzle seat fixed connection, and sealed face and the interior edge sealing connection of mounting hole, the middle part fixedly connected with of nozzle seat takes over.
In the lining pipe joint integrated structure, the middle part of the sealing surface is provided with the boss, the thickness of the boss is smaller than the thickness of the inner wall of the mounting hole, and the outer edge profile of the boss is inwards deviated by 1mm compared with the inner edge profile of the mounting hole.
In the lining pipe joint integrated structure, one side of the pressure plate is provided with an extension block protruding outwards, the extension block is accommodated in the mounting hole, and the total thickness of the extension block and the boss is smaller than the wall thickness of the mounting hole.
In the lining pipeline connecting pipe integrated structure, the connecting pipe seat is provided with a threaded hole, a through hole penetrating through the threaded hole is formed in the position of the orthographic projection of the threaded hole on the pressing plate, a bolt is inserted in the through hole, and the tail end of the bolt is in threaded connection with the threaded hole.
The utility model discloses the theory is novel, compares with prior art, has realized that the mill prefabrication combines together with the field installation, can realize not blowing out of pump (single pump), and the construction degree of difficulty is little, the time limit for a project is short, the transformation expense is controllable. Meanwhile, the arrangement of the hand holes can meet the installation and future maintenance convenience.
Drawings
Fig. 1 is a sectional view of the sealing port of the connecting pipe of the present invention (in the drawing, a is a mounting hole, and B is an original pipeline);
fig. 2 is a schematic view of the structure of the socket of the present invention.
In the figure: 1. an external connection pipe; 2. a threaded hole; 3, sealing surface; 4, connecting a pipe seat; 5, pressing a plate; 6, bolts.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example (b): the utility model provides a lining pipeline takes over integral structure, includes and sets up the mounting hole that runs through, nozzle 4 and clamp plate 5 on original pipeline, be equipped with sealed face 3 on the nozzle 4.
When the pipe connecting seat 4 is inserted into the mounting hole and rotates, the periphery of the sealing surface 3 is just attached to the inner edge of the mounting hole (the sealing surface 3 can be milled by a milling machine, and the radian/curvature of the sealing surface is consistent with that of the inner wall of the original pipeline). Referring to fig. 1 and 2, in order to achieve the above-described effects, the mounting hole of the present embodiment is formed in an oblong configuration, and the stem 4 is also formed in an oblong configuration, and when mounting, the stem 4 is placed into the mounting hole with its side facing forward, and then turned forward, and reaches the position shown in fig. 1.
The reason for choosing the long round structure is as follows: firstly, in order to put into the mounting hole in the side direction, secondly, the bent angle junction of long round structure is more level and smooth, more is favorable to sealed.
The pressing plate 5 is located on the outer side wall of the original pipeline, and the pressing plate 5 is fixedly connected with the pipe connecting seat 4.
Referring to fig. 1 and 2, a threaded hole is formed in the connecting pipe seat, a through hole (a threaded structure can be arranged in the through hole) is formed in the position of the orthographic projection of the threaded hole on the pressing plate, a bolt 6 is inserted into the through hole, and the tail end of the bolt 6 is in threaded connection with the threaded hole. During installation, the bolt 6 is screwed down, namely the original pipeline is clamped by the pressure plate 5 and the pipe connecting seat 4, and the sealing connection between the sealing surface 3 and the inner wall of the original pipeline is realized.
In addition, a sealing gasket can be additionally arranged at the joint of the sealing surface 3 and the inner wall of the original pipeline. The sealing gasket is provided with a plurality of bulges to form multilayer sealing.
Further, referring to fig. 2, a boss is arranged in the middle of the sealing surface 3, the thickness of the boss is smaller than that of the inner wall of the mounting hole, the outer edge profile of the boss is offset inwards by 1mm compared with the inner edge profile of the mounting hole, an extending block protruding outwards is arranged on one side of the pressure plate, the extending block is accommodated in the mounting hole, and the total thickness of the extending block and the boss is smaller than the inner wall thickness of the mounting hole.
Referring to fig. 1, the boss and the extension block play a role in limiting and fixing in order to enable the pressing plate 5, the pipe connecting seat 4 and the original pipeline to be better matched.
The middle part of the connecting pipe seat 4 is fixedly connected with an external connecting pipe 1.
