| Valve composition | The valve is composed of a valve head and a valve stem. The temperature of the valve head is very high (570~670K for the inlet valve and 1050~1200K for the exhaust valve), and it also bears the pressure of the gas, the force of the valve spring and the inertia force of the transmission components. Its lubrication and cooling conditions are poor, so the valve must have certain strength, stiffness, heat resistance and wear resistance. The inlet valve is generally made of alloy steel (chromium steel, nickel chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chromium steel). Sometimes, in order to save heat resistant alloy, the exhaust valve head is made of heat resistant alloy and the rod is made of chrome steel, and then the two parts are welded together. |
| Material of valve | Valve materials in China are generally divided into 40Cr, 4Cr9Si2, 4Cr10Si2Mo, 21-4N and 23-8N. 5Cr8Si2, 4Cr9Si3, 21-2N, 21-12N, 23-8N, XB, etc. have been used in large quantities on some imported models. High temperature nickel base alloy has also been applied to exhaust valves of high load diesel engines. |
