GAS CONTROL VALVE Russian patent published in 2018 - IPC F23N1/00 

FIELD: gas industry.

SUBSTANCE: invention relates to a device for regulating a gas flow, in which it is possible to subsequently shift the given range of values of the controlled quantity, performed in a simple way, in order to optimise the temperature range set for the heating device, without violating the permitted conditions of use. To this end, a setting element which serves to change the position of a temperature-sensitive element and thus to actuate a switch for activating a valve has a threaded part that is screwable into the housing. In this case, the two are connected together in a rotationally secure manner via a releasable locking mechanism, wherein a tubular latching part that is firmly connected to the threaded part is arranged between the pot-like setting element, partially surrounding the threaded part with a recess, and the threaded part. By way of a stop element that protrudes from the end side, the latching part projects into a guiding contour which is formed by an end-side aperture located in the setting element.

EFFECT: regulation of gas flow.
