CN201281331Y - Single external ring fire type gas-burner - Google Patents

Abstract

The utility model relates to a single outer ring fire type fuel gas burner which comprises a fire distributor, a fire distributor seat and an induction tunnel. The single outer ring fire type fuel gas burner is characterized in that the fire distributor is formed by metal plank stuff with one-step moulding and the radial edge is provided with a plurality of fuel gas troughs along the radial direction; the fire distributor is formed by metal plank stuff with one-step moulding and comprises a chassis and an annular bulge surrounding the chassis; the annular bulge and the chassis form a burning cavity; the centre of the chassis is fixedly connected with a gas inlet pipe; a fire distributor cover is arranged on the fire distributor seat; the fuel gas troughs and the upper end face of the annular bulge form a burning fire hole; and the fire distributor cover is welded with the fire distributor seat. When the structure is adopted, the fire distributor and the fire distributor seat are formed by metal plank stuff with one-step moulding, the utility model reduces processing steps and has the advantage of simple processing compared with the prior art. The utility model is formed from one-step moulding, reduces labour hour, saves labour force and reduces cost compared with the prior art.

Description

The outer ring fire formula gas burner of a kind of list

Technical field
