ES291833U - Control valve with magnetic security group for extra-base counters from gas kitchens (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Control valve of magnetic type of safety for extra-flat countertops of gas cookers, which being of the type that incorporate a rod provided with the corresponding manual control for positional control of a regulating cone of the gas flow to the burner, stem that in turn it is axially displaceable to act on a general obturator, belonging to the safety device, obturator on which an electromagnet also acts, fed by a thermocouple, when said thermocouple reaches the sufficient temperature to generate the necessary energy for the excitation of the electromagnetic coil, retaining the shutter in opening situation and allowing the elimination of the manual pressure that must be supplied to the control up to this moment, is essentially characterized by being constituted from a first body, in which a perpendicular housing is defined to the countertop plane, according to the subsequent position n of the valve assembly, for implantation of the flow-regulating cone and its different accessories, said housing being closed by its lower area, the opposite to the emergency one of the control rod, and a lateral opening being defined in correspondence with this area. Wherein said housing communicates with the hollow interior of a second lateral body with respect to the first in which in turn the obturator belonging to the safety device and the corresponding electromagnetic coil for actuating it is established, so that the axis of such obturator is perpendicular to the manual actuator stem, having provided that these elements, manual actuator rod and obturator, are related to the collaboration of a rocker, implanted in the second body, on a tilting axis that is also perpendicular to the drive rod, as well as to the axis of the electromagnetic coil itself it is laterally offset, with respect to said rod, the useless balance incorporating one of its ends an elbow arm whose end section, parallel to its axis and offset laterally with respect to it, penetrates into the interior of the first body through the lateral opening thereof and is operatively facing the free end of the manually operated stem, while at the other end of the rocker a second elbow arm is established whose free end is operatively opposed and capable of axially striking the obturator associated with the mobile nucleus of the electromagnetic coil, with the particularity that the aforementioned rocker is assisted by a spring that tends to keep the same in an inoperative situation.
