The V-shaped crown in Spiral Wound Gasket is a crucial design feature that plays a significant role in improving gasket performance and sealing effectiveness.
The presence of the V-shaped crown endows Spiral Wound Gaskets with elasticity and resilience. This design enables the metal strip to undergo elastic deformation like a spring when subjected to pressure, effectively conforming to the flange surface and forming a reliable seal. Whether in static or partial dynamic sealing applications, the V-shaped crown ensures that the gasket can recover its original shape upon compression and pressure release, maintaining long-lasting sealing performance.
The V-shaped crown design effectively addresses unevenness and minor deformations of the flange surface. In practical applications, flanges may experience slight deformations due to thermal expansion and contraction or operational loads, posing challenges to sealing performance. The elasticity of the V-shaped crown allows the gasket to adapt to these deformations, maintaining uniform contact and sealing with the flange, preventing leakage caused by poor contact.
The V-shaped crown also enhances the pressure resistance of Spiral Wound Gaskets. In high-pressure environments, gaskets need to withstand substantial pressure, and the V-shaped crown design strengthens the gasket's structural integrity, enabling it to maintain stable sealing performance under high pressure without deformation or failure.
In addition to the aforementioned functions, the V-shaped crown also contributes to the positioning and stability of Spiral Wound Gaskets during installation. It helps accurately position the gasket between the flanges, preventing displacement or misalignment during installation, ensuring sealing performance with each installation.
The V-shaped crown, as a core design feature of Spiral Wound Gaskets, significantly improves gasket performance and practicality through its elasticity, adaptability to flange surface deformations, enhanced pressure resistance, and assistance in positioning during installation. In various industrial fields, particularly those with stringent sealing requirements such as refineries, chemical plants, and the energy sector, spiral gaskets, with their V-shaped crown design, have become a preferred sealing solution.
