Abstract

1,096,003. Valves. C. W. WIEGAND. July 30, 1965, No. 32813/65. Heading F2V. A pressure relief valve 12 is loaded by an adjustable spring 17 and as the inlet pressure approaches the predetermined actuating pressure a piston 41 acted upon by the inlet pressure moves and straightens a toggle 22, 24 so applying the additional loading a further adjustable spring 28 to the valve to prevent chattering and hence leakage. When the predetermined pressure is attained the toggle is forced over-centre to remove the additional loading and the valve opens against its main spring 17 only. The toggle which is reset by a lever 44 or a piston device is independent of the main spring and provides for normal valve operation should the additional loading means fail. The main spring may be dispensed with. The valve may be replaced by a burster disc with a reinforcing member actuated by the additional loading means.
