The method to avoid rubber joint leakage: Use special flanges for butterfly valves.

source:Songjiang Group    date:2024-3-14   

Shanghai Songjiang Vibration Absorber Co.,Ltd.’s technical department would like to introduce a method to prevent rubber joint leakage and increase the pressure resistance of rubber joints by using dedicated flanges for lap-joint style soft sealing.

Choosing the right lap-joint flange is essential to provide a complete, durable, and safe connection method; When selecting a pipe flat welding flange, please follow these standards (dedicated flanges for lap-joint style butterfly valves):

1.The inner diameter of the connection part of the water pipeline must be the same as the inner diameter of the rubber joint.

2.The flange connected to the water pipeline must have a smooth and flat flange contact surface to ensure maximum sealing space (as shown in the figure below). If the rubber joint does not have a tight connection with the water pipeline contact surface, noise, insufficient pressure, and leakage may occur.

The method to avoid rubber joint leakage: Use special flanges for butterfly valves.

As shown in the diagram, using dedicated flanges will achieve a 100% sealing effect. With 100% sealing, the rubber sealing surface will not leak or even rupture.

The method to avoid rubber joint leakage: Use special flanges for butterfly valves.

The photo above shows the dedicated flange for clamp-type soft-seal, also known as butterfly special flange, butterfly valve special flange, or rubber joint special flange.

It’s not that rubber joints are prone to leakage, but rather that there is a lack of understanding about this product. Rubber joint products are highly mature in the domestic market in China and are not new products. Therefore, it is hoped that everyone can install and use them according to the requirements, allowing the performance of rubber joint products to be fully realized.
