Abstract

1444739 Valves SOC ITALIANA TECNOMECCANICA LA PRECISA DI DR PEG DE STEFANI SAS 28 Nov 1973 [28 Nov 1972] 55241/73 Heading F2V [Also in Division G3] A pressure regulator for controlling gas supply to a burner has a delayed-opening feature to prevent violent ignition at the burner, the initial gas supply being provided through a variable by-pass 31, 33. The regulator comprises a casing 1 having an inlet 2 and an outlet 3 to the burner controlled by a valve member 9 which may be electromagnetically controlled or controlled by a thermostat. Until this valve is opened a regulator valve 16 remains closed under the influence of a helical spring 17, pressure being equal, because of the by-pass, on either side of the valve and also on either side of a diaphragm 11, to which the valve is attached by a stem 15, by reason of a duct 29 and holes 113 in a cover 13 which provides guidance for the stem. When the valve 9 is opened to ignite the burner the drop in pressure on the upper side of a diaphragm 20, the lower side being vented to atmosphere via a calibrated orifice 30, causes a stem 25 attached to the diaphragm to move, under the influence of a spring 26, towards the other diaphragm 11. Because there is a space between these two members, valve 16 is only opened after a delay and until this has occurred gas flow to the burner is restricted to that which passes through the by-pass throttle 31, 33.
