Description

A kind of straight flame lid

Technical field

The utility model relates to a kind of Domestic combustor, the fire cover that especially a kind of burner is used.

Background technology

At present efficient, the environmental protection of gas utensil, easily processing is that the direction of industry development and pursuit is current, and the fire cover ubiquity that burner is used, auxiliary air supplements, undermixing, temperature rise, cause the thermal efficiency not high, CO content in smoke is too high, and special environmental protection important indicator NOX fails to meet environmental protection and energy saving product requirement; Because the fire hole of fire cover is numerous, each fire hole must operation of an operation be processed simultaneously, and production efficiency and the quality of production are low.

Utility model content

The purpose of this utility model is: a kind of straight flame lid is provided, and the moulding of burner port time processing is made, and work efficiency is high, and product quality is high, and fuel gas buring is abundant.

The utility model is achieved in that a kind of straight flame lid, comprises fire cover body, and fire cover body comprises top cover board and barrel, and the lower end of barrel is provided with interface; Its special character is: described lamina tecti portion is positioned at some the muscle along diameter line on barrel inner surface;

On described top cover board, have the annular burner port on several concentric circles that are distributed in different-diameter, annular burner port connects top cover board thickness direction.

The straight flame lid of described one, its special character is: described muscle is square or is trapezoidal.

The straight flame lid of described one, its special character is: described top cover board is plane, or spherical curved surface shaped; Or conical.

The straight flame lid of described one, its special character is: on described muscle, guiding gutter is set, guiding gutter is relative with described annular burner port and communicate.

The straight flame lid of described one, its special character is: the moulding of described annular burner port time processing is made.

The straight flame lid of described one, its special character is: described annular burner port and the moulding of guiding gutter time processing are made.

The straight flame lid of described one, its special character is: the radial edges of described top cover board arranges first fire hole that ignites, first fire hole that ignites communicates with in described barrel;

Or in described barrel, be provided with second fire hole that ignites;

Or the radial edges of described top cover board arranges first fire hole that ignites, first fire hole that ignites communicates with in described barrel; In described barrel, be provided with second fire hole that ignites; First, second fire hole that ignites is adjacent.

A kind of straight flame lid of the utility model, owing to adopting such structure, the one-shot forming of annular burner port is made, can encircle lathe tool by correspondence can process at one time more, annular burner port inner wall smooth, and product quality is high, top cover board is spherical curved surface, and fuel gas buring is abundant, and efficiency is high.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of straight flame lid, comprises fire cover body 1, and fire cover body 1 comprises top cover board 2 and barrel 3, and the lower end of barrel 3 is provided with interface 4.

Described top cover board 2 is positioned at some the muscle 5 along diameter line on barrel 3 inner surfaces;

On described top cover board 2, have the annular burner port 6 on several concentric circles that are distributed in different-diameter, annular burner port 6 connects top cover board 2 thickness directions.

Described muscle 5 is square or is trapezoidal, has two muscle 5 and mutually vertical.

Described top cover board 2 is plane, or spherical curved surface shaped, also can be described as: the cross section of top cover board 2 is plane, or circular arc; Or conical.

On described muscle 5, guiding gutter 51 is set, guiding gutter 51 is relative with described annular burner port 6 and communicate.

Described annular burner port 6 and guiding gutter 51 1 moulding are made.

The radial edges of described top cover board 2 arranges first fire hole 71, the first fire hole 71 that ignites that ignites and communicates with in described barrel 3;

In described barrel 3, be provided with second fire hole 72 that ignites; First, second fire hole 71,72 that ignites is adjacent.

Above-described is only preferential embodiment of the present utility model. It should be pointed out that for the person of ordinary skill of the art, in the situation that not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
