Description

Technical Field

[0001] The present application relates to the technical field of water electrolysis hydrogen production, and in particular to an installation component and a flange anti-tilt installation method for a water electrolysis hydrogen production pipeline. Background Art

[0002] The development of green hydrogen energy from water electrolysis has ushered in opportunities. At present, the technology has been industrialized. The installation of hydrogen pipelines for water electrolysis is one of the important points and difficulties in the installation of water electrolysis hydrogen production. Hydrogen is a Class A explosive and dangerous flammable gas with flammable and explosive chemical properties. The flange group must not be tilted during the installation of the hydrogen pipeline to prevent hydrogen leakage.

[0003] The conventional method of assembling flanges for horizontal pipes is as follows: the point at the top of the pipe cross section is called the 0 degree point, the point at the bottom of the pipe cross section is called the 180 degree point, and the left and right points of the pipe cross section are called the 90 degree point and the 270 degree point respectively. The flange is pre-installed at the end of the horizontal pipe, and the flange is spot welded at the 0 degree position of the pipe. Then, a plumb line is placed on the upper part of the flange to check whether the plumb line fits the flange. If there is a gap, adjust the flange inclination until the plumb line fits the flange. Then, spot weld the flange at the 180 degree point of the pipe to ensure that the verticality meets the flange inclination requirements in accordance with the specifications. Then, rotate the flange 90 degrees. At this time, the original 270 degree point of the pipe cross section is rotated to the 0 degree point, and the original 90 Rotate the flange to the 180-degree point, repeat the above steps, spot weld the original 270-degree point first, then put a plumb line on the upper part of the flange to check whether the plumb line fits the flange. If there is a gap, adjust the flange inclination until the plumb line fits the flange, and then spot weld the flange at the original 90-degree point of the pipeline to ensure that the verticality meets the requirements of the flange inclination. The verticality deviation in both directions meets the requirements, and the flange inclination can be confirmed to be qualified.

In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0036] According to a first aspect of the present invention, there is provided a mounting assembly, such as Figure 1 and Figure 2 As shown, the installation assembly is used for installing the flange 2 of the water electrolysis hydrogen production pipeline 1, and the installation assembly includes a pipeline clamp and a flange positioning member.

[0037] In the following description, reference will be made to Figure 1 and Figure 2 The detailed structures of the pipe clamp and flange positioning member of the installation assembly are specifically described.

[0038] like Figure 1 and Figure 2As shown, in an embodiment, the pipe clamp may include a first clamping member 4, a second clamping member 5 and an adjusting member. The first clamping member 4 and the second clamping member 5 may be, for example, a rectangular plate supported by a metal material such as stainless steel or aluminum alloy. In an embodiment, the size of the rectangular plate may be, for example, 200 mm in length, 5 mm in width, and 150 mm in height. The first clamping member 4 and the second clamping member 5 can be connected by an adjusting member, and the adjusting member can include a first arc track 6 and a second arc track 7. The first arc track 6 and the second arc track 7 can be, for example, an arc structure supported by a metal material such as stainless steel or aluminum alloy. The arc structure is provided with an arc through hole along the central axis. The first arc track 6 and the second arc track 7 are connected by an adjusting bolt 8. The adjusting bolt 8 passes through the arc through hole provided by the first arc track 6 and the second arc track 7. The angle and position of the first arc track 6 and the second arc track 7 can be adjusted by locking or loosening the adjusting bolt 8. The first arc track 6 and the second arc track 7 are respectively connected to the first clamping member 4 and the second clamping member 5 by connecting bolts 9. In this way, when you want to change the spacing between the first clamping member 4 and the second clamping member 5, loosen the adjusting bolt 8, adjust the angle and position of the first arc track 6 and the second arc track 7, and then lock the adjusting bolt 8. In the embodiment, the width of the first arc track 6 and the second arc track 7 may be 24 mm, the width of the arc through hole may be 12 mm, and the adjustment bolt 8 may be, for example, a single-head M12 hexagonal bolt.

[0039] like Figure 1 , Figure 2 and Figure 6 As shown, in an embodiment, the flange positioning member may include a first positioning plate 10 and a second positioning plate 11. The first positioning plate 10 and the second positioning plate 11 may be, for example, a rectangular plate supported by a metal material such as stainless steel or aluminum alloy. In an embodiment, the size of the rectangular plate may be, for example, 100 mm in length, 5 mm in width, and 200 mm in height. The flange positioning member may also include a rotating shaft 21, and the first positioning plate 10 and the second positioning plate 11 may be connected to the first clamping member 4 and the second clamping member 5 respectively through the rotating shaft 21. The rotating shaft 21 is a structural member in the prior art, and may be, for example, a structure similar to a door shaft. The first positioning plate 10 and the second positioning plate 11 abut against the flange 2 to be installed. In this way, the first positioning plate 10 or the second positioning plate 11 are both formed with a positioning plane for abutting the flange, and the angle with the first clamping member 4 or the second clamping member 5 may be adjusted through the rotating shaft 21 to adapt to different types of flanges (for example, Figure 6As shown, when the flange is a neck flange 3, the first positioning plate 10 or the second positioning plate 11 forms an angle with the first clamping member 4 or the second clamping member 5, that is, when the flange is a planar flange, the positioning plane of the flange positioning member coincides with the planar flange, and at this time, the positioning plane is perpendicular to the electrolysis water hydrogen production pipeline 1; when the flange is a neck flange 3, the positioning plane of the flange positioning member forms an angle with the electrolysis water hydrogen production pipeline 1 to correspond to the angle of the neck of the neck flange 3).

[0040] It should be noted here that the metal materials selected for the above-mentioned components can effectively extend the life of the installation component and realize the function of multiple uses. In addition, the strength and rigidity of the installation component can also be increased.

[0041] The installation component adjusts the horizontality with the electrolysis water hydrogen production pipeline 1 through the pipeline clamp (it should be noted that the horizontality of the electrolysis water hydrogen production pipeline 1 mentioned here is the standard in the prior art. Since the electrolysis water hydrogen production pipeline 1 passes through the flammable and explosive hydrogen, the horizontality of the electrolysis water hydrogen production pipeline 1 needs to meet the operating standards), and abuts the flange 2 through the flange positioning piece to ensure the verticality of the flange 2 and the electrolysis water hydrogen production pipeline 1, thereby realizing the anti-tilt installation of the flange 2.

[0042] In addition, if Figures 3 to 6 As shown, according to the second aspect of the present invention, a flange anti-tilt installation method for a water electrolysis hydrogen production pipeline is provided, and the above-mentioned installation component is provided, and the flange 2 is installed on the water electrolysis hydrogen production pipeline 1 through the above-mentioned installation component.

[0043] The flange anti-tilt installation method of the water electrolysis hydrogen production pipeline comprises:

[0044] Adjust the horizontality of the electrolytic water hydrogen production pipeline 1 so that the horizontality of the electrolytic water hydrogen production pipeline 1 meets the operation standard;

[0045] Clamp the water electrolysis hydrogen production pipeline 1 by a pipeline clamp;

[0046] Pre-install the flange 2 at the end of the water electrolysis hydrogen production pipeline 1;

[0047] Adjust the angle of the positioning plane of the positioning part of the flange positioning member relative to the water electrolysis hydrogen production pipeline 1 so that the positioning plane abuts against the flange 2, thereby positioning the flange 2;

[0048] The positioned flange 2 is welded to the electrolytic water hydrogen production pipeline 1;

[0049] Remove the mounting assembly.

[0050] Specifically, the first step of the method for preventing the flange of the electrolytic water hydrogen production pipeline from tilting requires adjusting the level of the electrolytic water hydrogen production pipeline 1 so that the level of the electrolytic water hydrogen production pipeline 1 meets the operation standard (it should be noted here that the level of the electrolytic water hydrogen production pipeline 1 mentioned here is the standard in the prior art. Since the hydrogen passing through the electrolytic water hydrogen production pipeline 1 is flammable and explosive, the level of the electrolytic water hydrogen production pipeline 1 needs to meet the operation standard), as Figure 3 shown. In the embodiment, the level of the electrolytic water hydrogen production pipeline 1 can be adjusted by an adjustment assembly. The adjustment assembly can include an operation support (not shown), a channel steel 18, a first round steel 19, and a second round steel 20. The operation support can be, for example, a device in the prior art, and the level of the operation support meets the operation requirements of the electrolytic water hydrogen production pipeline 1. The channel steel 18 can be, for example, a steel material formed into a U-shaped structure. The first round steel 19 and the second round steel 20 can be, for example, stainless steel round steels with a diameter of 10 mm. The first round steel 19 and the second round steel 20 can be respectively welded to the two flange plates of the channel steel 18. In this way, the channel steel 18 can be placed on the operation support, the first round steel 19 and the second round steel 20 are placed away from the operation support, and then the electrolytic water hydrogen production pipeline 1 is placed on the first round steel 19 and the second round steel 20. In this way, the level of the electrolytic water hydrogen production pipeline 1 is ensured.

[0051] The second step requires clamping the electrolytic water hydrogen production pipeline 1 by a pipeline clamping member. Before clamping the electrolytic water hydrogen production pipeline 1 by the pipeline clamping member, lay wires on the operation support and place two parallel straight lines, as Figure 5 shown. In the embodiment, they can be, for example, a first reference line 12 and a second reference line 13. As shown in Figure 6, in the embodiment, they can be, for example, a third reference line 14 and a sixth reference line 17 (it should be noted here that Figure 6 shown is the installation of the necked flange 3. Therefore, a fourth reference line 15 and a fifth reference line 16 need to be additionally set. The included angles formed between the fourth reference line 15 and the fifth reference line 16 and the third reference line 14 and the sixth reference line 17 respectively can correspond to the angle of the neck of the necked flange to ensure that the necked flange 3 and the electrolytic water hydrogen production pipeline 1 meet the installation standard. In this way, corresponding to the above-mentioned first positioning plate 10 and second positioning plate 11, it is convenient for the installation of the necked flange 3). The distance between the two parallel straight lines is the same as the diameter of the electrolytic water hydrogen production pipeline 1. The pipeline clamping member is placed on the parallel straight lines, and by adjusting the first arc track 6 and the second arc track 7, the clamping surfaces of the first clamping member 4 and the second clamping member 5 are respectively made to coincide with the two parallel straight lines. In this way, the distance between the first clamping member 4 and the second clamping member 5 is adjusted to be the same as the diameter of the electrolytic water hydrogen production pipeline 1.

[0052] The third step is to pre-install the flange 2 at the end of the electrolytic water hydrogen production pipeline 1;

[0053] The fourth step is to abut the flange 2 with the flange locating piece. After the pipe clamping piece clamps the electrolysis water hydrogen production pipeline 1, the flange locating piece is close to the end of the electrolysis water hydrogen production pipeline 1 where the flange 2 needs to be installed. Then the first positioning plate 10 and the second positioning plate 11 are abutted against the flange 2 to be installed. In this way, the horizontality required for installation is ensured by the pipe clamping piece, and the verticality of the flange 2 is ensured by the flange locating piece.

[0054] Step 5: Figure 4 As shown, in the embodiment, the flange 2 is welded to the water electrolysis hydrogen production pipeline 1, and the welding can be, for example, spot welding.

[0055] Step 6: Dismantle the installation components to complete the installation. The dismantled installation components can continue to be put into use.

[0056] The flange anti-tilt installation method of the water electrolysis hydrogen production pipeline solves the problem of low efficiency and multiple flange direction adjustment when the flange 2 is installed on the water electrolysis hydrogen production pipeline 1. The flange anti-tilt installation method of the water electrolysis hydrogen production pipeline ensures the horizontality required for installation through the pipeline clamping member of the installation component, and ensures the verticality of the flange 2 through the flange positioning member of the installation component. The operation is simple, the use and assembly are convenient, and the method is safe and reliable. It is particularly suitable for large-scale flange assembly operations, improves the quality of pipeline construction, and increases the comprehensive benefits of the project. It has the characteristics of being fast, efficient, flexible, simple, and highly safe. In addition, the installation components can be reused, saving materials and being economical.
