It is a small, valve usually used to manually check if water is above the valve connection on a boiler or tank. There may be several of them at different heights on the boiler or tank. There is a handwheel on the valve, an inlet connection (which is attached to the boiler) and an outlet (usually left unconnected). When filling the boiler or tank, the try-cocks can be left open. Water coming from the try-cock means the tank is filled to at least that level. The valve is then closed.
