The manufacturer of Double Eccentric Butterfly Valve tells you that poor combustion will not only cause the exhaust temperature to rise, but also the formation of carbon in the combustion chamber. The increase in exhaust temperature makes the working environment of the exhaust valve worse, and the burning of the exhaust valve is aggravated after other conditions are superimposed.
The manufacturer of Double Eccentric Butterfly Valve tells you that part of the carbon in the combustion chamber will be discharged with the exhaust gas, and it will also get stuck on the sealing surface of the exhaust valve and the valve seat like the particles mentioned above. The manufacturer of Double Eccentric Butterfly Valve tells you that the heating temperature of heavy oil is not well controlled. The viscosity is too high, which makes it difficult to atomize the fuel injected into the cylinder. The sealing surface of the valve and the valve seat is contaminated by carbon deposits, and the impurities contained in the fuel are deposited as a layer of mixed carbon on the exhaust valve disc and the sealing cone of the valve seat after passing through various complicated thermal processes in the combustion chamber. The glassy particles are harder and more brittle, mixed with sodium sulfate, calcium sulfate, iron oxide and other substances.
The manufacturer of Double Eccentric Butterfly Valve tells you that when the thickness of this layer of glassy deposits is too large, cracks will occur under the impact force when the valve is closed. Valve burned out.
