VALVE STRUCTURE FOR BURNERS OF DOMESTIC GAS STOVES

摘要

Valve structure for burners of domestic gas stoves produced with aluminium alloys or aluminium of injection grade by pressure injection with final forging, comprising a valve body and a cover which has registration members to provide a self-positioning and assembly of the main components of the valve in order to eliminate all possibilities of radial and axial misalignment of said components and providing at the same time a gas tightness, a valve plug provided with passages co-operating with a cover cam provided with three steps intended to the safe and secure switching of the continuous gas flow from maximum flow positions to a minimum flow position, as well as a secure off position in a single operation, and a minimum flow control device intended to control the gas flow so that the burners can operate with a wide variety of fuel gas.
