Description

Technical Field

[0001] The utility model relates to the technical field of metal can sealing, in particular to a sealing structure for a metal containing can. Background Art

[0002] Metal containment tanks usually require reliable sealing structures to ensure that the substances inside do not leak or be contaminated by the outside world. The following are some common sealing structures used for metal containment tanks:

[0003] Welding seals: In the construction of metal containment tanks, welding can be used to seal the joints. This method can provide a very strong and reliable seal suitable for high pressure or high temperature environments.

[0004] Rubber gasket seal: Use rubber gaskets or sealing rings on the connection part to achieve sealing by pressing the connection parts. This method is suitable for lower pressure and temperature conditions and is usually used to seal the lid or bottom of a metal container.

[0005] Threaded connection seal: When using threaded connection, the seal is achieved through the close contact between the threads. At the threaded interface of the metal container, sealants or fillers can be used to enhance the sealing effect.

[0006] Flange seal: Metal holding tanks usually use flange connections at the inlet or outlet. Flange connections use bolts and gaskets to press two flange plates tightly together to form a seal. This method is suitable for parts that need to be frequently disassembled and assembled, such as pipe connections.

[0007] Magnetic Seals: In some cases, magnetic seals can be used to seal metal containment tanks. This method uses magnetic forces to hold two components together, forming a seal. Magnetic seals are often used in leak-free environments such as high vacuum or high purity gas applications.

[0008] For the current method of sealing with a gland, a rubber pad or a sealing rubber ring is provided on the outside of the gland to achieve sealing of the metal container at the port. However, after long-term use, the sealing rubber ring will be deformed and thus cannot effectively guarantee stable and effective sealing of the port. Utility Model Content
