Abstract
PURPOSE:To regulate pressure securely by regulating the extent of opening of a valve seat according to the pressure of a fluid on a secondary side to a pressure plate. CONSTITUTION:When the pressure of a fluid in a secondary pipe 32 rises above that of a fluid operating on a valve plate 8, pressure operating on a pressure plate 7 surpasses the pressure on the valve plate 8 to move the pressure plate 7 and a pressure rod 6 toward the valve plate 8, which separates from a main body 2 to open a branch hole 16. When the branch hole 16 is opened, air supplied from an intake 14 is branched from the branch hole 16 to a recessed part 4 and then discharged out of the main body 2 through an outlet 17, so the pressure of air supplied from a feed air opening 18 to a cylinder 22 drops. When the air pressure on the cylinder 22 drops, a spring 28 moves a valve rod 24 and a valve body 25 toward a valve seat 30 through a piston 23 to reduce the extent of opening of the valve seat 30, thereby decreasing the pressure of a fluid flowing into the secondary pipe 32.
