Lens Gaskets
Junio 240L Lens gaskets are reusable, as the sealing effect is generally achieved by elastic deformation of the surfaces. The projected sealing width bG is calculated in relation to the angle a, which forms the sealing surface against the direction of the force (tubular axis) depending on the E modulus EG and the surface pressure exerted by bG = 100 ·σ/ EG · r ·sinα.
Junio 240L Lens gaskets are impervious to overpressure. With increasing loads, the contact surface between the spherical lens surface and the spherical flange groove increases, so that the surface pressure only increases to a lesser extent.
A disadvantage with standard sealing lenses is that, at high pressures and temperatures, the sealing lens can bulge along the circumference and weaken the tension of the connection. Also, at greater nominal diameter, the flange can become stuck in the area of the raised face diameter d5 and lift up at the sealing diameter.
