Description

A new type of fire cover

technical field

The utility model relates to the technical field of stainless steel burners, in particular to a novel fire cover.

Background technique

The stainless steel burner with multi-head fire cover, the fire distribution seat processed by stainless steel and the fire cover processed by metal copper, because stainless steel and copper are two different metal materials, they cannot be directly welded, so the stainless steel fire distribution seat and copper material The fire cover cannot be fixed by welding.

The stainless steel fire distributor is generally formed by sheet metal stamping process. Therefore, the thickness of the stainless steel fire distributor must be thin, and the threaded structure on the metal parts must have a certain thickness. Obviously, the surface of the stainless steel fire distributor Can't be provided with screw thread structure, therefore, the surface of stainless steel fire distributor also can't be connected and fixed with copper material fire cover by thread structure.

Therefore, when the existing copper fire cover is connected with the performance of the stainless steel fire distribution seat, the copper fire cover is usually placed directly on the air outlet on the surface of the stainless steel fire distribution seat, and the friction between the fire cover and the air outlet If it is fixed, the connection strength between the fire cover and the fire distribution seat is not strong enough, and air leakage is prone to occur.

Therefore, further improvements are required.
