Outer ring distributor and manufacturing process thereof

Abstract

The embodiment of the invention discloses an outer ring distributor which comprises an inner side wall of an annular structure and an upper cover. An ignition groove, ignition holes and fire outlet holes are formed in the upper cover, the inner side wall and the upper cover are integrally formed through stainless steel materials, and the inner side wall is arranged to be of a circular ring structure extending in the vertical direction. The upper cover comprises an inner slope extending outwards and obliquely upwards from the top of the inner side wall, a top plane horizontally extending outwards from the top of the inner slope, an outer slope extending outwards and obliquely downwards from the outer side of the top plane, and an outer side wall vertically extending downwards from the bottom of the outer slope. The bottom surface of the outer side wall and the bottom surface of the inner slope surface are at the same or similar height. The fire outlet holes are distributed in the outer slope surface in the circumferential direction at an inclined angle relative to the horizontal plane. The embodiment of the invention further discloses a corresponding manufacturing process of the outer ring distributor. The outer ring distributor has the advantages of being simple in structure, low in cost, small in size, firm, durable and high in combustion energy efficiency.

Description

technical field [0001] The invention relates to the field of gas appliances, in particular to an outer ring fire distributor and a manufacturing process thereof. Background technique [0002] Stainless steel has a high melting point, high hardness, perfect stretchability, fire resistance, and fast heat dissipation. It is very suitable as the main material of the fire dispenser and is an ideal raw material for manufacturing fire dispensers. However, due to its high hardness, stainless steel materials also have the disadvantages of being difficult to process and difficult to integrally form. As a result, in the prior art, fire distributors made of stainless steel have complex structures, large cavity structures, high consumables, and heavy weight. They are mainly swirling fire types and have low energy efficiency. [0003] Compared with stainless steel, copper is expensive, has a low melting point, is soft, and is easy to deform, oxidize, and volatilize, so it is not suitable...

AI Technical Summary

Problems solved by technology

[0004] Copper material is not only expensive, but also has a low melting point, is easy to deform and leak, or even volatilizes, has a short service life, and the manufacturing process is not environmentally friendly. Moreover, the top of the copper will overflow after high-temperature die-casting, which will block the fire outlet and affect the fire effect.
