Determination of the size of mechanical seal gasket:

68 68A domestic standardized mechanical seal gaskets (rectangular or similar rectangular cross-section gaskets). The dimensions refer to the width and thickness of the gasket contact surface, which will determine the position of the gasket reaction force, which is a calculation method An important parameter of the force of the flange and bolt. The size of the gasket directly affects the sealing performance of the seal.

According to the formula of the radial leakage of fluid through the gap in Chapter 1, the leakage is inversely proportional to the seal width. When the pressure stress on the gasket is constant (the gap is constant), generally speaking, the gasket (a flat gasket is Ex) Wider means good sealing performance. But when the width exceeds a certain value, the leakage rate (rate) is basically unchanged.　　480.html,
