What is the purpose of an inlet valve?

a valve in the cylinder head of an internal-combustion engine that opens at the proper moment in the cycle to allow the fuel-air mixture to be drawn into the cylinder.

What is inlet and outlet valve?

These are the heart valves of the ship, sealing the combustion chamber. Inlet and outlet valves are components subject to high demands and high temperatures. The outlet valve in particular is exposed to stress from the flow of hot exhaust gases as it opens during the discharge cycle.

What type of valve is an inlet valve?

The valve through which a fluid is drawn into the cylinder of a positive-displacement engine, pump, or compressor. Also known as induction valve.

What comes through the inlet valve?

The valve which allows mixture into the cylinder is the inlet valve; the one through which the spent gases escape is the exhaust valve. They are designed to open and close at precise moments, to allow the engine to run efficiently at all speeds.

What is the function of the main inlet valve?

Main Inlet Valve. Function. For the hydro-power station with bifurcated pipe, create safe working conditions for the repair or maintenance of Turbine-generator set. During turbine-generator set stopping, reduce the water leakage and shorten the restart time. Prevent the expansion of turbine runaway accident.

What kind of steel is an inlet valve made of?

Fuel is allowed to the cylinder by the inlet valve. When closed, the valve seals the combustion space tightly. The valves are usually made of austenitic stainless steel which is a corrosion and heat-resisting material. Inlet valve is subjected to less heat is usually made of nickel-chromium alloy steel.

Where are the inlet valves on a fire fighting truck?

Two inlet valves A, one at each side of the trailer, fitted with hose coupling valves and chained caps of the same type and size as mounted on the fire-fighting truck, should be provided. Via each inlet the FLC can be pumped from the main FLC storage tank via hoses and check valve B into the tank mounted on the trailer.

Why are Inlet and outlet valves in the top closed position?

The inlet and outlet valves are both in the top closed position offering double protection against bypass leakage. As long as the trap has been sized correctly to handle the condensate flow, the unit can be left in this position during start up and normal plant operation. Figure 18.49. Method of operation of packaged unit
