Metal gear gasket of mechanical seal:

124 pump mechanical seal metal toothed gasket is easy to leave indentations on the flange sealing surface after use, so it is generally used for parts that are less disassembled. The working pressure is 1.96-19.6MPa.

In the manholes of some large high-pressure vessels that are often dismantled, a layer of soft pads are attached to both sides of the pads, such as asbestos rubber sheets, flexible graphite sheets, aluminum sheets, copper sheets, etc., which not only protect the flange surface, but also mechanically seal Performance is also significantly improved. The reason is that this kind of combined tooth-shaped cushion is mainly relied on the soft cushion to easily produce plastic deformation during pre-compression, and is in good contact with the flange surface to form a seal. The soft pad used in the combined tooth-shaped pad is very thin and contacts the flange after being compressed. One side is a flat surface, and the other side is a tooth shape. The thickness of the pressed part of the tooth tip is only 0.1~0.250mm, the plastic flow gap is very small, and the tooth tip bites, it is difficult for the flat gasket to produce plastic flow, and it can maintain a high sealing pressure. In addition to increasing the elasticity of the combined pad, the toothed pad also strengthens the soft gasket, so that materials with lower strength such as asbestos rubber sheets can withstand high pressure.　　497.html,
