The collar of the bunsen burner
The needle valve or flow valve controls the flow of gas into the Bunsen Burner.
It's a gas tap that controls flow of gas and turns it on and off.
A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.[1][2][3][4][5] The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both.
to let the gas get to the burner
There are two adjustable parts on the Bunsen burner, the knob to control gas flow and the rotation of the collar to control air flow. The gas flow control, adjusts the size of the flame by controlling how much gas is burned. While the collar controls the intensity of the flame by controlling how completely the gas burns, more complete combustion the hotter the flame. These are the two parts to adjust a Bunsen burner, I hope I have answered your question.
It controls the air/gas mixture.

the deffirence between terrill burner & bunsen burner is that terrill burner has a greater flexibility in the adjustment of the air-gas mixture which bunsen burner cannot .

A Bunsen burner focuses a lot of heat straight upward, instead of outward. This allows you to heat something up at close range without your hand or anything else getting too hot. Most Bunsen burners have a valve that controls gas flow and adjustable vents where you can control the amount of air that feeds the flame. Bunsen burners are a safe, practical way to apply heat in a chemistry lab.
The gas regulator controls the fuel gas flow.

The parts of a Bunsen burner include: the barrel, gas hose, base, collar, air hole and gas flow valve. The Bunsen burner is a small adjustable gas burner that is mainly used in scientific laboratories.
The needle valve is used to control the amount of gas flowing to the burner. The air valve controls the amount of air.
