Description

Technical Field

[0001] This utility model relates to the field of tube sheet technology, specifically to a corrosion-resistant 304 stainless steel tube sheet. Background Technology

[0002] Stainless steel tube sheets are pipe fittings made of stainless steel and are mainly used to fix piping systems. They are formed by drilling, threading, and welding of round stainless steel plates. They are widely used in industrial pipelines (such as petroleum, chemical, and medical fields) and construction fields (such as decoration projects and kitchenware manufacturing), especially in working conditions that require withstanding temperature differences or complex stresses. Common materials include 304 stainless steel and 316 stainless steel, which have the characteristics of high strength, corrosion resistance, and easy processing, and can meet the strength and sealing requirements of different working conditions.

[0003] In existing 304 stainless steel pipe sheets, pipes are directly inserted into the pipe holes of the 304 stainless steel pipe sheet, and the connection between the pipe and the 304 stainless steel pipe sheet is sealed by welding. However, during the welding process, incomplete welding sometimes occurs. Furthermore, over long-term use, leaks may sometimes occur at the weld between the 304 stainless steel pipe sheet and the pipe, affecting the sealing quality. Additionally, the 304 stainless steel pipe sheet has a protruding center, which can allow water to remain on the outer ring of the protruding center. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a corrosion-resistant 304 stainless steel tube sheet includes a tube sheet body 1, which is made of 304 stainless steel. A groove 2 is provided on the water inlet side of the tube sheet body 1, with the water inlet diameter completely overlapping the groove 2. A pipe hole 3 is provided in the middle of the tube sheet body 1 corresponding to the area of ​​the groove 2. A first rubber ring 4 is installed inside the tube hole 3 of the tube sheet body 1, and the first rubber ring 4 protrudes from the surface of the pipe hole 3. By passing the pipe through the pipe hole 3 and welding the pipe to the tube sheet body 1, the welding between the pipe and the tube sheet body 1 is achieved. At the same time, the first rubber ring 4 further seals the gap between the pipe hole 3 and the pipe, improving the sealing effect. When water is transported, the water will completely pass through the area of ​​the groove 2, and the water remaining in the groove 2 can be drained through the pipe, improving the water flow effect.

[0023] like Figures 1 to 5 As shown, the tube sheet body 1 has a first receiving hole 5 at the middle position corresponding to the tube hole 3, and the first rubber ring 4 is located inside the first receiving hole 5.

[0024] By pre-opening a first storage hole 5 inside the tube hole 3 of the tube sheet body 1, the first rubber ring 4 can be stored and positioned to prevent the first rubber ring 4 from falling off or sliding.

[0025] like Figures 1 to 5 As shown, the tube sheet body 1 has a first chamfer 6 at the water inlet end corresponding to the tube hole 3.

[0026] When the pipe is welded to the tube sheet body 1 through the pipe hole 3, the weld point can remain in the area of ​​the first chamfer 6 to prevent the weld point from protruding from the end face of the tube sheet body 1.

[0027] like Figures 1 to 5 As shown, the tube sheet body 1 has a second chamfer 7 at the water outlet end corresponding to the tube hole 3.

[0028] When the pipe is passed through the pipe hole 3, the design of the second chamfer 7 makes it easy for the pipe to be inserted into the pipe hole 3.

[0029] like Figures 1 to 5 As shown, a second storage hole 8 is provided on both sides of the tube sheet body 1. A second rubber ring 9 is installed inside the second storage hole 8. The second rubber ring 9 is located in the area where the two tube sheet bodies 1 are in contact.

[0030] The second rubber ring 9 is stored and positioned through the second storage hole 8. At the same time, the second rubber ring 9 can seal the area where the two tube sheet bodies 1 are in contact.

[0031] like Figures 1 to 5As shown, the tube sheet body 1 undergoes anti-corrosion processing, such as electrochemical processing and coating anti-corrosion processing, to further improve the anti-corrosion performance of the tube sheet body 1.

[0032] like Figures 1 to 5 As shown, a connecting hole 10 is provided between two adjacent pipe holes 3. The two ends of the connecting hole 10 pass through the welding ring between the tube sheet body 1 and the pipe, so as to realize the connection between the two adjacent pipe holes 3.

[0033] This utility model provides a corrosion-resistant 304 stainless steel tube sheet, and its specific working principle is as follows:

[0034] When the device is in use, the pipe is passed through the pipe hole 3 and welded to the tube sheet body 1 to achieve the welding between the pipe and the tube sheet body 1. At the same time, the gap between the pipe hole 3 and the pipe is further sealed by the first rubber ring 4 to improve the sealing effect. When transporting water, the water will pass through the area of ​​the groove 2 completely, and the water remaining in the groove 2 can be drained through the pipe to improve the water flow effect.

[0035] 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.
