Introduction to the Forms and Differences of Valve Bonding Joints

Release Date: August 06, 2018

Forms and differences of bonded joints:

Metal bonding joints may be subject to tensile, shear, and torsional forces, uneven tearing, and peeling forces. Depending on the force, there should be different forms of adhesive joints, but the most basic joint structures are mainly planar adhesive joints, slot joints and socket joints (Figure 1). The flat bonding joint (Figure 1a) has a large bonding area and can obtain high bonding strength. Slotted joints (Figure 1b) can be decomposed into tensile and shear forces in any direction, so higher bonding strength is also obtained. The socket joint (Figure 1c) inserts a part into the hole of another part. Because the force applied by the socket joint under load is pure shear, its bonding area is large and its strength is high. It is suitable for the bonding of round pipes and rods, but the uniformity of the thickness of the adhesive layer is not easy to control. A special operating tool is required to ensure the concentricity of the center position of the two parts, thereby ensuring the uniformity of the adhesive on the bonding surface. Improve bonding quality and strength.
