Rubber diaphragm is one of the important accessories for various pumps and valves. Rubber membranes are mainly used in valves, regulating valves, automatic mechanical follow-up devices, switches, and counters for flow, pressure, differential, liquid level, constant temperature volume thermal compensation, etc. Its advantages lie in high work reliability, good composites, long working life, and low cost. In low-pressure operations, the force generated by strengthening the diaphragm with a cloth clip may become excessive. For this type of assignment, it is entirely possible to use rubber membranes constructed from uniformly elastic all rubber structures, which can also provide the same advantages as reinforced membranes with cloth clips, while increasing the economic benefits of utilizing uniformly elastic structures. Uniform elastic structure can be applied to various rubbers, with some high-strength fabrics such as nylon, polyester fabric, and even aramid fabric sandwiched inside.
