Description of High Quality Rubber Diaphragm: 

For the machinery industry, diaphragm is a circular membranous elastic sensitive element. The form of diaphragm mainly includes three kinds: flat diaphragm, vertical chain diaphragm and corrugated diaphragm. The flat diaphragm can be divided into various forms according to whether the surrounding area is fixed, whether there's a central hole and the pressure distribution. The most commonly used diaphragm is the flat diaphragm. 

Fabric Reinforced Diaphragm is diaphragm reinforced with fabric inside, fabric strengthens diaphragms' breaking strength and the pressure it can hold. 

Rubber is a commonly used material of diaphragms. Rubber diaphragm is mostly used in valves, control valves, automatic mechanical servo devices, switches and counters. Its advantages include high reliability, good complexity, long working life and low cost.
