Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel end caps, in particular to a thick-walled duplex stainless steel end cap. Background Art

[0002] Thick-walled duplex stainless steel heads are of great significance in the industrial field. Duplex stainless steel is a material with excellent strength and corrosion resistance. The manufacture of thick-walled duplex stainless steel heads can provide better pressure resistance and stability, thereby ensuring the long-term stable operation of industrial equipment. Since thick-walled duplex stainless steel heads have high strength and stability, they can provide better safety during use.

[0003] The existing stainless steel heads are generally made of stainless steel during use. When the mechanical material is in operation, the stainless steel heads are subject to certain wear and tear, which makes the heads thinner under long-term wear and tear, and the sealing performance of the heads deteriorates, causing leakage of the device, affecting the normal use of the heads. At the same time, due to the thin structure of the heads, it is easy to cause deformation or damage inside the heads due to internal or external influences, which reduces the usability of the heads.

[0004] The existing patent (announcement number: CN211593561U) is a wear-resistant stainless steel head, which relates to the field of head technology, including a head body, a support rod is fixed on the upper part of the interior of the head body, a spring is arranged inside the support rod, support bars are fixed on both sides of the support rod, and the bottom ends of the support rod and the support bar are connected with support plates. This wear-resistant stainless steel head is provided with a replacement plate, bolts, and a wear-resistant layer. When in use, the replacement plate is separated from the head body. After installing the replacement plate, the head body is fixed by bolts. During use, the wear-resistant coating prevents the internal material from being worn on the head body, and the wear-resistant coating delays the wear. After long-term use, the pigment coating is subject to certain wear, and the head body is removed. The replacement plate is made of transparent polyurethane, and the wear-resistant coating is observed to see if it is severely worn so as to replace the internal replacement plate, thereby achieving the effect of wear-resistant and convenient observation of the head.

[0005] In view of the above problems, existing patents have provided solutions, but most of the existing heads have poor bearing capacity and are easily deformed after being subjected to long-term impact.

[0006] Therefore, a thick-walled duplex stainless steel head is proposed. Utility Model Content

[0031] A thick-walled duplex stainless steel end cap comprises an end cap body 1, a reinforcement component 2 is arranged at the bottom of the end cap body 1, and an elastic component 3 is arranged between the reinforcement component 2 and the top of the end cap body 1;

[0032] The reinforcement assembly 2 includes a first reinforcement rod 201, a second reinforcement rod 202, a rotating sleeve 203, a first thread 204 and a second thread 205. One end of the first reinforcement rod 201 is arranged on the bottom inner wall of the head body 1, one end of the second reinforcement rod 202 is arranged on the inner wall of the head body 1 and corresponds to the first reinforcement rod 201.

[0033] Specifically, Figure 1As shown, the elastic component 3 includes a support plate 301, a head inner sleeve 302, a reinforcement ring 303, a buffer bin 304 and a buffer spring 305. The support plate 301 is fixedly arranged on the inner side of the bottom of the head body 1, the head inner sleeve 302 is fixedly arranged on the top inner wall of the head body 1, the reinforcement ring 303 is arranged at the bottom of the head inner sleeve 302 and is located on the support plate 301, the buffer bin 304 is fixedly arranged on the inner side of the top of the head inner sleeve 302, and the buffer spring 305 is arranged between the bottom of the buffer bin 304 and the support plate 301 and the buffer springs 305 are evenly arranged in an array therebetween.

[0034] By setting the reinforcement component 2 including the first reinforcement rod 201, the second reinforcement rod 202, the rotating sleeve rod 203, the first thread 204 and the second thread 205, when in use, the first reinforcement rod 201, the second reinforcement rod 202 and the rotating sleeve rod 203 are installed on the bottom of the head body 1, and then the rotating sleeve rod 203 is rotated to drive the first reinforcement rod 201 and the second reinforcement rod 202 at both ends to move relative to each other. Since the first thread 204 and the second thread 205 are arranged in opposite directions, the first reinforcement rod 201 and the second reinforcement rod 202 move oppositely, so that the bottom of the head body 1 can be supported to prevent the head body 1 from being deformed. The elastic component 3 including the support plate 301, the head inner sleeve 302, the reinforcement ring 303, the buffer bin 304 and the buffer spring 305 are set. When in use, when the fluid inside the head body 1 impacts the support plate 301, the buffer bin 304 and the buffer spring 305 will unload it to prevent a large impact on the inside of the head body 1.

[0035] Specifically, Figure 1 As shown, a first slot 4 is formed on the inner wall of the head inner sleeve 302 , a second slot 5 is formed on one side of the support plate 301 , and reinforcing rods 6 are disposed inside the first slot 4 and the second slot 5 .

[0039] Specifically, Figure 1As shown, a sealing ring 12 is fixedly provided inside the straight cylinder portion 8 of the head body 1, and the sealing ring 12 is made of rubber material.

[0040] Specifically, Figure 1 As shown, a welding ring 13 is fixedly provided on the outer side of the bottom of the head body 1 , the welding ring 13 is aligned with the bottom of the straight cylinder part 8 , and the welding ring 13 is made of the same material as the head body 1 .

[0041] The reinforcement column 10 can provide a certain protection for the support plate 301 to prevent the support plate 301 from being deformed too much due to stress. The reinforcement column 10 can provide a certain protection for the support plate 301. At the same time, the convenient handle 11 facilitates the installation of the head body 1 to prevent the surface of the head body 1 from being too smooth and difficult to operate. The sealing ring 12 can further protect the installation of the head body 1.

[0042] By adopting the above technical solution, the problem that most existing heads have poor bearing capacity and are easily deformed after being subjected to long-term impact is solved.

[0043] Working principle: When the present application is used, the first reinforcing rod 201, the second reinforcing rod 202 and the rotating sleeve rod 203 are first installed at the bottom of the head body 1, and then the rotating sleeve rod 203 is rotated to drive the first reinforcing rod 201 and the second reinforcing rod 202 at both ends to move relative to each other. Since the first thread 204 and the second thread 205 are arranged in opposite directions, the first reinforcing rod 201 and the second reinforcing rod 202 move relative to each other, so that the bottom of the head body 1 can be supported to prevent the head body 1 from being deformed. When the fluid impacts the support plate 301, the buffer bin 304 and the buffer spring 305 will unload the load to prevent a large impact on the inside of the head body 1. The reinforcing column 10 provides certain protection for the support plate 301 to prevent the support plate 301 from being deformed excessively. The reinforcing column 10 can provide certain protection for the support plate 301. At the same time, the convenient handle 11 facilitates the installation of the head body 1 to prevent the surface of the head body 1 from being too smooth and difficult to operate, and the sealing ring 12 will further protect the installation of the head body 1.
