Description

Technical Field

[0001] This utility model relates to the field of adapter plate technology, specifically a cast adapter plate connection device with a buffer structure. Background Technology

[0002] Adapter plates are intermediate transitional components that connect two or more parts. Their core function is to solve problems such as interface mismatch between different parts, the need for functional expansion, or the need to adjust the installation position. They are commonly found in connection systems for pipelines, equipment, and instruments.

[0003] In existing technologies, adapter plates are typically connected to flanges on both sides of the connecting pipes via graphite rings. The graphite rings abut against both the flanges and the adapter plate, respectively, to provide a seal. However, with prolonged use, the graphite rings are prone to wear, leading to a decrease in sealing performance and causing media leakage. Furthermore, during installation, the mounting holes on the adapter plate usually need to be precisely aligned with the mounting holes on the flanges. In actual use, this requires repeated adjustments to the adapter plate or flanges, and takes a considerable amount of time to install the adapter plate correctly. Utility Model Content

[0004] The purpose of this invention is to solve the problems that graphite rings are easily worn down after long-term use, leading to a decrease in sealing performance and leakage of the medium. At the same time, during installation, the mounting holes on the adapter plate usually need to be precisely aligned with the mounting holes on the flange. In actual use, the adapter plate or flange needs to be adjusted repeatedly, which takes a long time to install the adapter plate. Therefore, a cast adapter plate connection device with a buffer structure is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A casting adapter plate connection device with a buffer structure is designed, including an adapter plate body and mounting holes. The inner wall of the adapter plate body is machined with multiple mounting holes. The adapter plate body has a sealing structure inside. Both sides of the adapter plate body are provided with connection structures. Both sides of the adapter plate body are connected to flanges by bolts and nuts. The outer wall of the flange is fixedly connected to a first connecting pipe and a second connecting pipe, respectively.

[0006] This setting involves passing bolts through the mounting holes on the adapter plate body and the flange, respectively, and then tightening the nuts to secure the adapter plate body and the flange together.

[0007] Preferably, the sealing structure includes a first groove, and a wave spring and a graphite ring are sequentially inserted into the inner wall of the first groove from the outside to the inside. The two sides of the wave spring abut against the graphite ring and the inner wall of the first groove, respectively. The first groove is machined on both sides of the inner wall of the adapter plate body.

[0008] This setting allows for the application of additional elastic force via a specially designed wave spring, ensuring the graphite ring remains firmly pressed against the flange.

[0009] Preferably, the outer sides of the graphite rings are all tightly abutted against the flanges.

[0010] This feature provides a reliable seal for the media (such as molding sand, cooling water, and hydraulic oil) transported in the casting system through the placement of graphite rings.

[0011] Preferably, the connection structure includes inserts, the inner sides of which are fixedly connected to the adapter plate body, and the outer walls of which are inserted into the second groove.

[0012] This feature: The insert has beveled surfaces on both sides, which can act as a guide, making it easier for it to enter the second groove.

[0013] Preferably, the second groove is machined on the inner wall of the flange.

[0014] This feature allows the mounting holes on the flange to align with those on the adapter plate body through the cooperation of the second groove and the insert block, eliminating the need for repeated adjustments.

[0015] The present invention proposes a casting adapter plate connection device with a buffer structure, which has the following advantages: by cooperating with the adapter plate body and the sealing structure, the corrugated spring is placed into the first groove, and then the graphite ring is placed into the first groove. When the first and second pipes are used to transport the casting medium, slight vibration will occur. The corrugated spring can apply additional elastic force to keep the graphite ring pressed against the flange, reducing the possibility of reduced sealing performance and leakage of the medium.

[0016] By cooperating with the adapter plate body and the connecting structure, the insert block is inserted into the second groove. At this time, the multiple mounting holes on the adapter plate body are aligned with the mounting holes on the flange, eliminating the need for repeated adjustments. Then, the bolts are passed through the mounting holes on the adapter plate body and the flange, and the nuts are tightened onto the bolts. The adapter plate body and the flange can then be installed in a relatively short time. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-6 In this embodiment, a casting adapter plate connection device with a buffer structure includes an adapter plate body 7 and mounting holes 8. The inner wall of the adapter plate body 7 is machined with multiple mounting holes 8. The interior of the adapter plate body 7 is provided with a sealing structure 2. Both sides of the adapter plate body 7 are provided with connecting structures 5. Both sides of the adapter plate body 7 are connected to flanges 4 by bolts and nuts. The outer wall of the flanges 4 is fixedly connected to the first connecting pipe 1 and the second connecting pipe 3 respectively.

[0020] The sealing structure 2 includes a first groove 201. A corrugated spring 202 and a graphite ring 6 are sequentially inserted into the inner wall of the first groove 201 from the outside to the inside. The two sides of the corrugated spring 202 abut against the graphite ring 6 and the inner wall of the first groove 201, respectively. The first groove 201 is machined on both sides of the inner wall of the adapter plate body 7. The outer sides of the graphite ring 6 abut against the flange 4. The corrugated spring 202 is placed into the first groove 201, and then the graphite ring 6 is placed into the first groove 201. When the first pipe 1 and the second pipe 3 are used to transport the casting medium, slight vibration will occur. The corrugated spring 202 can apply additional elastic force (which can play a buffering role) to keep the graphite ring 6 abutting against the flange 4, reducing the possibility of decreased sealing performance and leakage of the medium.

[0021] The connecting structure 5 includes insert blocks 501. The inner sides of multiple insert blocks 501 are fixedly connected to the adapter plate body 7. The outer walls of the insert blocks 501 are all inserted into the second grooves 502. The second grooves 502 are all machined on the inner wall of the flange 4. When the insert blocks 501 are inserted into the second grooves 502, the multiple mounting holes 6 on the adapter plate body 7 are aligned with the mounting holes on the flange 4. There is no need to make repeated adjustments. Then, the bolts are passed through the mounting holes 6 on the adapter plate body 7 and the mounting holes on the flange 4. After that, the nuts are tightened on the bolts. Thus, the adapter plate body 7 and the flange 4 can be installed in a short time.

[0022] Working principle: When using a cast transition plate connection device with a buffer structure: The operator places the wave spring 202 into the first groove 201, then places the graphite ring 6 into the first groove 201, and then inserts the insert block 501 into the second groove 502. At this time, the multiple mounting holes 6 on the adapter plate body 7 are aligned with the mounting holes on the flange 4, without the need for repeated adjustments. Then, the bolts are passed through the mounting holes 6 on the adapter plate body 7 and the mounting holes on the flange 4, and then the nuts are tightened on the bolts. The adapter plate body 7 and the flange 4 can be installed in a short time. After the adapter plate body 7 is installed, when the first pipe 1 and the second pipe 3 are used to transport the casting medium (such as cooling water, hydraulic oil, etc.), slight vibration will occur. The wave spring 202 can apply additional elastic force (which can play a buffering role and reduce the damage to the graphite ring 6), so that the graphite ring 6 is always pressed against the flange 4, reducing the possibility of reduced sealing and leakage of the medium.

[0023] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
