SAFETY VALVE FOR GAS COMBUSTION DEVICE Russian patent published in 2019 - IPC F23N5/10 

FIELD: machine building.

SUBSTANCE: safety valve for gas combustion device includes housing including inlet and outlet gas pipelines, magnetic group, bushing and fasteners for attachment of bushing and magnetic group to housing. Magnetic group is located in the housing cavity, provides opening or closing of the gas channel from the inlet to the outlet pipeline and comprises an electromagnet and its support. Bushing is inserted into the magnetic group and is connected to the support. Fasteners comprise a fastening element and a ring-shaped flange. Fastening element has a cylindrical central part, wherein the free end of the latter is adapted to the housing geometry for holding the fastening element on the body. Annular flange extends radially inward. Fastening element is located on the bushing so that the annular flange presses the bushing base to the housing and the magnetic group. Free end of the central part is squeezed on the valve body so that the fastener remains attached to the body.

EFFECT: invention allows simplifying assembly of safety valve.
