Rubber diaphragm is a flexible diaphragm made of rubber or other elastic materials that can move freely in space or other devices. It is usually used as a seal between two components, such as a valve, to regulate or guide the flow of fluids, gases, and steam.
Rubber diaphragm have many uses, including regulating flow, controlling pressure, sealing the space within the two components of the system, and preventing backflow between the two components.
In some cases, rubber diaphragm need to be able to withstand various temperatures, pressures, and corrosive substances. When selecting a diaphragm for a specific system or equipment, certain factors need to be considered, including fluid type, temperature, pressure, size and shape limitations of the casing, and expected results.
Rubber diaphragm, if designed properly, have many advantages compared to other methods of sealing two parts. It can provide long-lasting sealing because it can withstand various conditions and even work with specific liquids that corrode metal units.
Rubber diaphragms have been applied in many industries, including automotive engineering, medical technology, and other fields. In automotive engineering, rubber diaphragms are used for fuel injectors, actuators, and brake servo systems.
