Increasing the amount of fuel gas flow through the tube by opening the needle valve will increase the size of the flame.
22.
The needle valve may be located proximal or distal to the inlet port; these two types of flowmeter are respectively called'non-compensated'or'compensated '.
23.
Placing a gate or needle valve on the reactor's outlet side will improve flow characteristics compared to control from the inlet side.
24.
The fuel is sprayed with the help of a nozzle that is opened and closed with a needle valve, operated with a solenoid.
25.
When the solenoid is not activated, the spring forces the needle valve into the nozzle passage and prevents the injection of fuel into the cylinder.
26.
A "'needle valve "'is a type of valve having a small port and a flow, although it is generally only capable of relatively low flow rates.
27.
The fuel mixture is automatically altitude-controlled by bleeding higher pressure air from chamber A to the chamber B as it flows though a tapered needle valve.
28.
In compensated flowmeters, the ball will initially jump as the gas flows through the tube before being released through the needle valve just before the outlet.
29.
With sensitive valves, such as needle valves, the gas can slowly be allowed through the valve so that the pressure increase is slow on the low-pressure side.
30.
The spindle and / or seat of a needle valve, especially one made from brass, are easily damaged by excessive turning force when shutting off the flow.
