Product Description
Cummins QSL9 Engine part Intake Vlave Exhaust Valve 4981794 4981795 For Sany 150T Crawler Crane
Intake Vlave Exhaust Valve 4981794 4981795 is fitting on USA QSL9 Cummins Diesel Engines . The Cummins engine model is QSL ISL Series. The valves are designed to pump air into the engine and out of the combustion exhaust.In terms of engine structure, it is divided into intake valve and exhaust valve.The function of the intake valve is to draw air into the engine and burn it with fuel.The purpose of the exhaust valve is to exhaust and dissipate heat after combustion.
The valve is composed of the valve head and the rod.Valve head temperature is very high (intake valve 570~670K, exhaust valve 1050~1200K), but also under the pressure of gas, valve spring force and transmission component inertia force, its lubrication, cooling conditions are poor, the requirements of the valve must have a certain strength, stiffness, heat resistance and wear resistance.Generally, the intake valve is 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, heat-resistant alloy is used for the exhaust valve head and chromium steel for the rod, and then the two are welded together.

The shape of valve head includes flat top, spherical top and horn top.It's usually flat-topped.Flat-headed valve head is simple in structure, convenient in manufacture, small in heat absorption area, small in mass, and can be used for intake and exhaust valve.Spherical ceiling valve is suitable for exhaust valve, which has high strength, low exhaust resistance and good elimination effect of exhaust gas, but it has large heating area, large mass and inertia, and complex processing.The trumpet type has a certain streamline shape, which can reduce the intake resistance, but its head is heated to a large area, only suitable for the intake valve.

Valve cone Angle is the valve sealing surface Angle, generally 45°, some is 30° . The valve with 30° is generally used for the inlet valve because of the same lift, small taper, large valve through the end face and small intake resistance. However, due to the thin edge of the head of the valve with small taper, small stiffness, poor sealing and thermal conductivity.The thickness of valve edge is generally 1~3mm, to prevent damage caused by impact with valve seat or burn out by high temperature.To reduce intake resistance and improve cylinder intake efficiency, most engines have larger intake valves than exhaust valves.Used intake and exhaust valves are also different colors.
The valve rod is cylindrical, reciprocating in the valve tube, and its surface must be superheated and polished.The shape of the end of the valve rod depends on the fixed form of the valve spring. The commonly used structure is the two-half lock plate to fix the spring seat. The end of the valve rod has a ring groove to install the lock plate.
