What Is a Diaphragm Seal?
A diaphragm seal is a device used as a seal to prevent leakage of liquids or gases.
It employs a diaphragm made of flexible material, placed around a shaft or pipe, and deforms it by applying pressure from above and below to close any gaps. The operating principle involves placing a diaphragm and deforming it by applying pressure to close the gaps. Widely utilized in industries such as chemical, food, and medical devices, diaphragm seals prevent the leakage of corrosive or toxic substances.
The components consist of the diaphragm and the supporting part, where the diaphragm blocks the passage of liquids or gases, and the supporting part provides support to the diaphragm. Various materials are used, and the key features include high sealing performance, easy maintenance, and high durability. Important considerations when using diaphragm seals include the environmental compatibility of materials, attention to pressure, and regular checks for diaphragm degradation.
