Tri-mixed gas (fuel, oxygen and air) lamp cap

Abstract

The invention relates to a tri-mixed gas (fuel, oxygen and air) lamp cap. The lamp cap is composed of a lamp shell and a lamp wick, wherein, the shape of the lamp shell is formed by superposing a cylinder part 1 and a truncated cone part 2; the truncated cone part 2 is internally provided with a circular threaded hole 3 which can be connected with a gas supply pipe; the lamp wick is positioned ina circular groove 4 of the lamp shell, and a space is arranged between the lamp wick and the bottom of the circular groove 4; the side wall of the cylinder part 1 is provided with two symmetrical circular threaded holes 5 for fixing the lamp wick; the outer side wall of a lamp wick cylinder is provided with two symmetrical arch grooves 6; a row of small up-down through holes are arranged at the center of the cylinder and are paralleled to the bottom surfaces of the arch grooves; the left and right sides of a row of the small holes 7 are provided with two deep grooves 8 which are parallel to arow of the small holes 7; the bottom surfaces of the two arch grooves 6 are provided with three small holes 9 which are communicated with the deep grooves 8; the lower side walls of the arch grooves 6 are provided with three small holes 10 which pass through the bottom surface of the cylinder and are corresponding to the small holes 9; and each deep groove 8 is clamped with two rectangular corrugated sheets 11 and one rectangular flat sheet 12 which is positioned between the corrugated sheets so as to form mixed gas channels.

Description

Technical field [0001] The invention relates to a gas appliance, in particular to a gas lamp holder for preparing a control bottle. Background technique [0002] The gas lamp holders used in the existing controlled bottle machine are all two-gas mixed lamp holders, that is, the lamp holder burns a mixture of gas (natural gas or liquefied gas) and oxygen. This kind of lamp holder is not suitable for burning a three-gas mixture, that is, it is not suitable for burning a mixture of gas, oxygen and air. Since the oxygen content in the air is only 21%, 79% is non-combustible, non-combustible nitrogen and carbon dioxide. If the existing two-gas mixture lamp holder burns the three-gas mixture, air cannot be added. When there is wind around the environment, the flame It is easy to be blown out and extinguished, causing waste of control bottles and bringing great safety hazards. Summary of the invention [0003] The purpose of the present invention is to provide a three-gas mixed lamp ca...

Problems solved by technology

Since the oxygen content in the air is only 21%, and 79% is non-combustible, non-combustible nitrogen and carbon dioxide, if the existing two-gas mixture lamp burns three-gas mixture, air cannot be added. When there is wind around the environment, the flame will burn. It is easy to be blown out and extinguished, resulting in waste of control bottles and a great safety hazard
