Aiming at the problems that the operation precision is difficult to guarantee, the construction risk is high and the safety coefficient is low during the resetting operation of the explosion-proof flange plate in the prior art, the newly designed explosion-proof flange plate alignment tool is shown in figures 1 to 3. The newly designed anti-explosion flange plate alignment tool 1 mainly comprises a support base body 10 and a calibration assembly 40. The support base 10 mainly plays a role in bearing and pre-positioning, and the calibration assembly 40 mainly plays a role in accurately positioning and applying external force. Specifically, a cavity 11 for receiving a pair of flanges to be aligned is formed in the support base 10, an opening 12 is formed at one side of the support base 10, and a pair of flanges to be aligned is protruded from the opening 12 into the cavity 11. The support substrate 10 is positioned entirely across the outside of a pair of flanges to be aligned, with corresponding threaded holes (one of which is shown at 33 in FIG. 2 to show the approximate location of the threaded holes) in both flanges located in the cavity 11 inside the support substrate 10. The alignment member 40 is generally rod-shaped, and the alignment member 40 passes through the support base 10 and extends into the corresponding threaded holes 33 of a pair of flanges to be aligned. The alignment assembly 40 is operable to rotate so that the corresponding threaded holes 33 of a pair of flanges to be aligned are on the same axis, and the alignment assembly can be aligned by inserting bolts through the aligned threaded holes and tightening the bolts. Compared with the existing manual adjustment mode, the explosion-proof flange plate is adopted to align the tool 1 for alignment operation, so that the production stop time can be reduced, and the operation is simpler, more convenient and more labor-saving. The whole process of adjusting the operation well is all gone on in the outside of ring flange, can stop to take place the crowded accident of hindering of personnel when the maintenance fastening, also can not appear the instrument maloperation on the pipeline, cause the cracked accident of pipeline.
The structure of the anti-explosion flange aligning tool 1 is described in detail as follows: referring to fig. 1 and 3, the support base 10 includes first and second end portions 13 and 14 formed on opposite sides of the opening 12, respectively, so that the relative positions of the flanges are well defined by the first and second end portions 13 and 14 disposed across the outer sides of a pair of flanges to be aligned during operation. The first end 13 and the second end 14 are preferably designed to extend in the same direction as the mounting direction of the flange. Therefore, the relative position of the flange plates does not need to be changed during alignment operation, the installation direction of the flange plates is kept unchanged, the alignment operation of the two flange plates can be performed in the normal flow of an oil field metering station or a gathering and transportation station, the operation is not influenced, and a special operation area does not need to be arranged. For convenience of description, the flange disposed adjacent to the first end portion 13 is defined as a first flange 31, and the flange disposed adjacent to the second end portion 14 is defined as a second flange 32. Referring to fig. 2 and 3, when the first flange 31 and the second flange 32 extend into the cavity 11, the first flange 31 vertically abuts against the inner wall 15 of the first end portion 13, and the alignment member 40 extends from the second end portion 14 through and into the corresponding threaded holes of the first flange 31 and the second flange 32.
It will be appreciated that the same explosion proof flange alignment fixture 1 may be required to perform flange alignment operations of various sizes, and therefore, the alignment assembly 40 is specifically designed to be comprised of the threaded rods 17 and the alignment rods 18. In cooperation with the alignment member 40, an internally threaded hole 16 is formed in the second end portion 14 of the support base 10, and the internally threaded hole 16 extends in a direction perpendicular to the flange. The threaded rod 17 passes through the internally threaded hole 16 and is in threaded engagement with the internally threaded hole 16. A positioning rod 18 is detachably fixedly connected to the front end of the threaded rod 17, i.e. the end close to the first end 13. The locating bar 18 may have a variety of dimensions, such as 20-1, 20-2, and 20-3 shown in FIG. 4. Alternatively, the positioning rod 18 is provided with an internally threaded tube section 22 matching the threaded rod 17, and the internally threaded tube section 22 of the positioning rod 18 is bolted to the threaded rod 17. The locating rod 18 has a tapered end 20 formed thereon. The cone base and the cone tip of the conical end portion 20 are distributed in sequence in the direction from the second end portion 14 to the first end portion 13.
To ensure a certain alignment angle, the height of the tapered end 20 is preferably designed to be 2 to 3 times that of the internally threaded pipe section 22, while also ensuring that the tapered end 20 has a certain taper to facilitate subsequent alignment. As shown in fig. 4, the external diameter of the internally threaded tubular section 22 may be designed to be equal to or greater than the external diameter of the threaded rod 17 to ensure the structural stability of the tapered end 20. When the outer diameter of the internally threaded pipe section 22 is designed to be larger than the outer diameter of the threaded rod 17, the internal thread thereon may be designed at the center of the internally threaded pipe section 22. After both the first flange 31 and the second flange 32 extend into the cavity 11 and hold the first flange 31 against the inner wall 15 of the first end 13, operatively rotating the threaded rod 17 to drive the positioning rod 18 towards the first end 13, the positioning rod 18 extending into the threaded hole 33 in the second flange 32, the outer surface of the tapered end portion 20 contacts the inner surface of the threaded bore 33 of the second flange 32, and as the threaded shaft 17 is advanced, the tapered end portion 20 passes completely through the threaded bore 33 of the second flange 32 and into a corresponding threaded bore (not shown) in the first flange 31, the outer surface of the tapered end portion 20 contacts the inner surface of the threaded hole in the first flange 31, and as the threaded rod 17 is further advanced, the tapered end portion 20 fully penetrates the threaded hole in the first flange 31, so that the corresponding threaded holes of the first flange 31 and the second flange 32 are located on the same axis. In order to facilitate the turning of the operating threaded rod 17, a handle 19 is preferably provided on one side of the threaded rod 17.
The inner surface 21 of the support base 10 between the first end 13 and the second end 14 may be designed to be flush to accommodate alignment between the two flanges of the pipeline without other components. However, in an actual working site, the outside of the pipeline may be provided with other parts such as the solenoid valve, the corresponding circuit of the solenoid valve, and the explosion-proof isolating shell, which may cause inconsistency of working space outside the pair of flanges to be aligned, and in order to ensure that the alignment of the threaded holes can be accomplished in this case, it is preferable to provide the inner surface 21 of the support base 10 between the first end portion 13 and the second end portion 14 as an upwardly curved surface or other irregular curved surface, and with this structure, the support base 10 can be adapted to align the threaded holes on the two flanges under the working condition that the outside of the pipeline is provided with other parts.
Inevitably, after the positioning rod 18 passes through the threaded hole of the first flange 31 completely, the tip of the tapered end portion 20 of the positioning rod 18 may contact the inner surface of the support base 10, and in order to avoid spark and thus explosion when contacting, it is preferable that the positioning rod 18 and the support base 10 are made of copper metal.
