Description

Technical Field

[0001] This utility model relates to the field of metal end cap technology, specifically a metal end cap with strong safety performance. Background Technology

[0002] Metal heads, also known as end caps, are components used to seal the ends of containers, isolating them from the internal and external media. They are primarily connected to the vessel body by welding and are a major pressure-bearing component of pressure vessels. Metal heads are widely used in various container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers, and separation equipment.

[0003] For example, a metal end cap for a pipe, as disclosed in Chinese Patent Publication No. CN218914177U, includes an end cap, which is the main body of the metal end cap for the pipe. The outer edge of the end cap is provided with a welding ring, an inner surface layer, which is disposed on the inner surface of the end cap, an outer surface layer, which is disposed on the outer surface of the end cap, the inner surface layer and the outer surface layer are integrally disposed, an adhesive layer, which is disposed on the inner surface of the outer surface layer, a seepage-proof layer, which is disposed inside the outer surface layer, and a wear-resistant layer, which is disposed on the outer surface of the end cap.

[0004] The metal end caps in the aforementioned patents can only achieve high sealing performance. However, existing metal end caps are connected by welding, and the weld seam is relatively weak compared to the inner wall of the pipe. Furthermore, the weld seam lacks protective components, resulting in a relatively weak connection between the end cap and the pipe. Therefore, an improved device is needed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a metal end cap with strong safety performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal end cap with high safety performance, comprising a support device, a covering device slidably mounted on the outer ring of the support device, the support device comprising a positioning rod, an extension plate, an end cap and an alignment ring, the alignment ring being fixedly mounted on the outer ring of the end cap, the extension plate being fixedly mounted on the outer ring of the end cap, and the positioning rod being fixedly mounted on the top end of the extension plate.

[0007] Preferably, the covering device includes a positioning slide rod and a protective ring, wherein the positioning slide rod is slidably inserted into the top end of the protective ring, and the positioning slide rod is arranged in a ring.

[0008] Preferably, a pipe is welded to the top of the end cap, an iron ring is welded to the outer ring of the pipe and the end cap, and an alignment sleeve is installed at the bottom of the outer ring of the pipe.

[0009] Preferably, the protective ring is slidably fitted onto the outer ring of the end cap and the pipe.

[0010] Preferably, both the top of the protective ring and the interior of the alignment ring are provided with circular holes, and the circular holes are distributed in a ring shape.

[0011] Preferably, an alignment ring is fixedly installed on the outer surface of the pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When this device is in use, the positioning rod can be inserted into the inside of the pipe when the end cap is spliced ​​with the pipe, so that the round hole inside the alignment ring can be aligned, improving the accuracy of the positioning rod being inserted into the protective ring. At the same time, the iron ring is welded at the junction between the pipe and the end cap, which prevents external objects from directly contacting the weld between the pipe and the end cap. Meanwhile, the protective ring is located on the outer ring of the iron ring, which prevents external objects from directly contacting the iron ring, improving the protective performance of the iron ring, thus completing the work of protecting the weld between the pipe and the end cap.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4The present invention provides an embodiment of a metal end cap with high safety performance, including a support device 1, a covering device 2 slidably installed on the outer ring of the support device 1, the support device 1 including a positioning rod 3, an extension plate 4, an end cap 5 and an alignment ring 6, the alignment ring 6 being fixedly installed on the outer ring of the end cap 5, the extension plate 4 being fixedly installed on the outer ring of the end cap 5, and the positioning rod 3 being fixedly installed on the top end of the extension plate 4.

[0021] The covering device 2 includes a positioning slide rod 7 and a protective ring 8. The positioning slide rod 7 is slidably inserted into the top of the protective ring 8, and the positioning slide rod 7 is arranged in a ring, which facilitates the protective ring 8 to slide onto the outer ring of the alignment ring 6.

[0022] A pipe 9 is welded to the top of the end cap 5. An iron ring 11 is welded to the outer ring of the pipe 9 and the end cap 5. An alignment sleeve 10 is installed at the bottom of the outer ring of the pipe 9 to facilitate the docking and assembly of the pipe 9 and the end cap 5.

[0023] The protective ring 8 is slidably fitted onto the outer ring of the end cap 5 and the pipe 9, and can protect the outer surface of the iron ring 11.

[0024] Both the top of the protective ring 8 and the interior of the alignment ring 6 have circular holes arranged in a ring shape, which facilitates the insertion of the positioning slide rod 7 into the interior of the protective ring 8 and the alignment ring 6.

[0025] A positioning ring 6 is fixedly installed on the outer surface of the pipe 9. The ring passes through the round hole inside the protective ring 8 without penetrating the bottom end of the protective ring 8, so that the positioning slide rod 7 can be placed inside the protective ring 8.

[0026] Working principle: In use, first place the end cap 5 on the ground, then place the pipe 9 on top of the end cap 5. At this time, because the alignment sleeve 10 has a slot inside, when the pipe 9 is connected to the end cap 5, the slot inside the alignment sleeve 10 can be vertically aligned with the positioning rod 3, so that the pipe 9 can be accurately spliced ​​with the end cap 5. Subsequently, when the pipe 9 is connected to the end cap 5, the user can operate external welding equipment to weld the gap at the junction of the end cap 5 and the pipe 9, thus connecting the end cap 5 and the pipe 9. After connecting them together, the weld seam can be ground smooth. Then, the iron ring 11 is placed around the weld seam junction of pipe 9 and end cap 5. The top and bottom ends of the iron ring 11 are then welded to pipe 9 and end cap 5 respectively, so that the iron ring 11 can be located on the outer periphery of the weld seam of end cap 5 and pipe 9, thereby protecting the weld seam. Then, the protective ring 8 is slidably fitted onto the outer ring of pipe 9 and end cap 5 until the arc groove inside the protective ring 8 slides and fits onto the aligning ring 6, so that the protective ring 8 can be temporarily placed and supported. Furthermore, when the inner ring of the protective ring 8 is in contact with the outer ring of the pipe 9 and the end cap 5, the round hole inside the top of the protective ring 8 can be vertically aligned with the round hole inside the alignment ring 6. At this time, the positioning slide rod 7 can be inserted into the interior of the protective ring 8 and the alignment ring 6, so that the protective ring 8 can be restricted to the periphery of the iron ring 11, thus protecting the iron ring 11 and improving the safety performance of the weld between the end cap 5 and the pipe 9. When this device is in use, the iron ring 11 is welded to the outer surface of the weld at the junction of the end cap 5 and the pipe 9, so that the weld can be protected firstly. At the same time, the protective ring 8 is installed on the periphery of the iron ring 11, so that the surface of the iron ring 11 can be protected, preventing external objects from directly impacting the iron ring 11 and improving the protective performance of the iron ring 11. In addition, when the protective ring 8 is installed, the inner wall of the protective ring 8 has an arc groove, and the arc groove can be looped around the outer ring of the alignment ring 6, so that the protective ring 8 can be temporarily placed, and the protective ring 8 can be rotated and adjusted along the outer ring surface of the alignment ring 6 to complete the work.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
