ssure intended to blow off. Can a safety-valve be too large? Yes, if too large, the velocity of steam through the valvemay carry along with it the water in the boiler, therebylifting the water from the sheet. Valves should be made SAFETY-VALVE 49 large enough to carry off all the steam the boiler… … Figure 12. pressure at which a valve will blow, what data must beobtained from the valve? Area of valve, weight of lever, distance from fulcrum tocentre of gravity of lever, weight of valve and stem, and dis-tance from fulcrum to centre of valve stem. 50 PRACTICAL STATIONARY ENGINEERING How do you…
