Lens gasket ring
The lens ring is a line seal. The lens gasket is made by cutting various metal materials.
Product advantages: The product is resistant to high temperature, high pressure, strong acid and alkali, and is mainly used for sealing high temperature and high pressure pipeline flanges.
Choose lens gaskets. Under high temperature and high pressure, other gaskets are easy to leak and blow. The line seal has large expansion and contraction, large compensation, and easy compression.
Uses: In the connection of high-pressure pipelines, the lens pad sealing structure is widely used. The sealing surface of the lens pad is spherical, in contact with the tapered sealing surface of the pipe, and the initial state is a loop. Under the action of the pre-tightening force, the lens pad is plastically deformed at the contact point, and the loop line becomes a loop belt, and the sealing performance is better. Since the contact surface is naturally formed by a spherical surface and an inclined surface, the gasket is easy to center
Scope of application: The current angle-type high-pressure valve end flanges in my country's general machinery industry are sealed with lens gaskets. The applicable nominal pressure is 16.0～32.0Mpa; the nominal diameter is 3～200mm; the operating temperature is -30～200℃.
