Rubber Triangle Diaphragm

描述

rubber triangle diaphragm

Corrugated diaphragms are circular elastic sensing elements featuring concentric annular corrugations, typically fabricated from vulcanised rubber and metal composites. Their profile (i.e., the shape of the corrugations) encompasses various forms including circular arc, sinusoidal, triangular, and trapezoidal. Consequently, triangular diaphragms constitute a specific type of corrugated diaphragm characterised by triangular corrugations.

The core characteristics of triangular diaphragms are intrinsically linked to their triangular corrugation structure:

1. High sensitivity: The corrugated structure (including triangular forms) effectively enhances the diaphragm’s deformation sensitivity, enabling significant displacement when subjected to pressure differentials.

2. Design flexibility: By adjusting thickness, hardness, and corrugation parameters (such as wave height and wave pitch), a balance between stiffness and pressure resistance can be achieved to meet diverse application requirements.

3. Material diversity: Common materials include nitrile rubber and 316L stainless steel, adapting to diverse operational environments such as high-temperature resistance and corrosion resistance.

Function of the Triangular Diaphragm

1. The primary function of the triangular diaphragm is to serve as a pressure-sensitive element. It utilises pressure differentials across its surfaces to generate displacement, thereby enabling pressure sensing or control functions. Widely employed in instrumentation, pneumatic control valves, and other fields, it constitutes a critical component in numerous industrial devices.
