Valve seat is one of the components of diesel generator set. It is a circular surface machined on the cylinder block or cylinder head. The valve cone is sealed or seated on the valve seat, which provides a sealing surface for the intake and exhaust valves to prevent gas leakage. The valve seat can also help dissipate the heat accumulated on the valve. Types of valve seats There are two types of valve seats: integrated and embedded. Similar to valve guides, the integrated valve seat serves as the cylinder head Part of it is directly cast; The embedded valve seat uses a metal ring as the valve seat, which is pressed into the cylinder body and needs to be ground to the correct angle. Engines with aluminum cylinder heads typically use embedded valve seats. Inlaid valve seats can be made of cast iron, hardened cast iron, high chromium steel, and tungsten chromium cobalt alloy (very hard steel). To ensure the normal operation of the diesel generator set , the...
