Abstract

519,568. Valves. HURST, W. F. F. MARTIN-, BRITISH THERMOSTAT CO., Ltd., DELANEY, C. T., and GALLAY, Ltd. June 20,1938, No. 18279. [Class 135] A relief valve device particularly adapted for use on steam heating systems for aircraft cabins is adapted to relieve excessive pressure or vacuum in the system and also to permit the escape of air from the system during the process of warming up. The air-venting comprises an annular lift valve l secured to a thermal bellows m charged with the same liquid as is used in the system or with one having a slightly lower boiling point. The. thermal bellows is adjustably secured to the lower perforated end of a sleeve e normally held by a spring h with a shoulder f in engagement with a ledge g on a flanged plate b secured to an outer cylindrical casing a. The sleeve e which carries a synthetic rubber seat y for the valve l is secured to the lower end of a bellows j which in turn is fixed to the top of the casing. The pressure and vacuum relief r is housed within the valve l and is normally held closed by a spring u housed in a guide socket s. With excessive vacuum the valve r is lifted away from its seat against the action of the spring u. With excessive pressure the bellows j is compressed against the action of the spring allowing both valves l and r to move upwards until the valve r is unseated by contact with a pin v adjustably secured to the casing cover. This cover is provided with outlet apertures c leading to a discharge conduit d.
