Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sealed chamber technology, and specifically relates to a flexible sealing connection structure for sealed chambers. Background Technology
[0002] Sealed chambers primarily provide a specific atmosphere for physical and chemical experiments, pharmacological experiments, and the production of special products. They are widely used in industries such as lithium battery research and development and production, physical and chemical research, powder metallurgy, biopharmaceuticals, special welding, OLEDs, materials processing, and fine chemicals.
[0003] Currently, connections between multiple sealed chambers are mostly rigid, with relatively fixed relative positions. This can lead to difficulties in moving large or heavy chambers. If the placement of the chambers to be connected is off, adjustments can be difficult, or even prevent connection altogether. Even if the chambers can be connected, gaps in the sealing surfaces due to misalignment can cause air leakage and contamination. Furthermore, different sealed chambers may be in a state of vibration or relative stillness due to varying equipment and operating conditions. If chambers in different states need to be connected, the vibrating chambers will inevitably negatively impact the still chambers, and vice versa. Therefore, solving these technical problems is a major challenge in the industry. Utility Model Content
[0004] To address the aforementioned issues, this utility model provides a flexible sealing connection structure for sealed chambers. This flexible sealing connection solves the problems of difficulty in positioning multiple sealed chambers when they are docked, as well as how sealed chambers under different working conditions can dock without affecting each other and ensure good sealing performance.
[0005] A flexible sealing connection structure for a sealed chamber includes a first sealed chamber shell and a second sealed chamber shell, which are connected to each other. A first mating flange is installed on the mating surface of the first sealed chamber shell, and a second mating flange is installed on the mating surface of the second sealed chamber shell. A flexible sealing gasket is provided on the flange surfaces of the first and second mating flanges, and the flexible sealing gasket is pressed against the flange surfaces of the first and second mating flanges by a pressing assembly.
[0006] As a preferred embodiment, the clamping assembly includes a first pressure plate and a second pressure plate. The first pressure plate clamps the flexible sealing gasket to the flange surface of the first mating flange using a first fastener. The second pressure plate clamps the flexible sealing gasket to the flange surface of the second mating flange using a second fastener.
[0007] As a preferred embodiment, the first fastener and the second fastener are fastening screws and / or fastening bolts.
[0008] As a preferred embodiment, the flexible sealing gasket is provided with openings corresponding to the first fastener and the second fastener.
[0009] As a preferred embodiment, the first sealing chamber shell is connected to the first mating flange by welding or threading, and the second sealing chamber shell is connected to the second mating flange by welding or threading.

[0018] Please see Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a flexible sealing connection structure for sealed chambers, specifically including a first sealed chamber shell 1 and a second sealed chamber shell 2. The first sealed chamber shell 1 and the second sealed chamber shell 2 are connected to each other and are formed by bending and welding metal sheets. A first mating flange 3 is installed on the mating surface of the first sealed chamber shell 1, and a second mating flange 7 is installed on the mating surface of the second sealed chamber shell 2. A flexible sealing gasket 4 is provided on the flange surfaces of the first mating flange 3 and the second mating flange 7.

In this embodiment, the first sealed chamber shell 1 and the second sealed chamber shell 2 achieve a sealed connection between the two sealed chambers through the flexible sealing gasket 4. At the same time, due to the certain elasticity of the flexible sealing gasket 4, the two sealed chambers can achieve a certain limit of relative movement, thereby realizing the flexible sealing connection function between the two sealed chambers.
