Abstract
The utility model discloses a multi-function flame nozzle used for hydrogen-oxygen fuel. One end of the flame nozzle is provided with a gas inlet pipeline for the hydrogen-oxygen fuel, and the gas inlet pipeline for the hydrogen-oxygen fuel is connected with a gas output pipe of a hydrogen-oxygen fuel generator; the other end of the flame nozzle is provided with at least one hydrogen-oxygen fuel combust hole; a safety flame stopping valve is arranged at the inner part of the flame nozzle; the safety flame stopping valve is composed of at least one poromeric annular or sheet-shaped labyrinth type flame stopping sheet and a flame stopping sealing gasket, wherein, the flame stopping sheet is formed by metal particles in a die-casting mode; the flame stopping valve is compacted in the flame nozzle by fastening nuts; a flame stopping chamber is formed by a connecting space which is arranged between the flame stopping valve and the hydrogen-oxygen fuel combust holes. The utility model has the advantages of simple structure, high flame stopping efficiency, high safety, and wide purposes.
Description
The utility model relates to a kind of multi-functional flame nozzle that is used for hydrogen-oxygen fuel.
At present, the flame nozzle that the hydrogen-oxygen fuel burning is used, an end is provided with the hydrogen-oxygen fuel admission line, and the other end is provided with a flame combustion hole, and its inside is provided with safe fire retardant device, just string one dry type fire insulation valve on the hydrogen-oxygen fuel air inlet pipeline.In use, because distance is bigger between valve body and nozzle, when causing the oxyhydrogen combustion tempering, the gas communication stroke is long, can not in time the fire resistance be gone out.And because there are a lot of shortcomings in the dry type fire insulation valve, when having moisture as hydrogen or oxygen gas when output, sealing gasket in the dry type fire insulation valve is soaked, the dry type fire insulation valve will not play the back-fire relief effect, so in a single day, tempering takes place, the pipeline of hydrogen-oxygen fuel generation equipment will be blown up, this not only causes damage, to in time change fire insulation valve, and influence production efficiency.In addition, its cost height is installed inconvenience, is unsuitable for the hydrogen-oxygen fuel combustion apparatus and uses.
The purpose of this utility model is to improve the deficiency of prior art and a kind of multi-functional flame nozzle that is used for hydrogen-oxygen fuel is provided, its once mounting can be used for a long time, does not need to connect in addition fire retardant device, and back-fire relief is effective, flame combustion is even, guarantees the stable operation of hydrogen-oxygen fuel generation device security.
For achieving the above object, the utility model is taked following design: it is that a end at the flame nozzle is provided with the hydrogen-oxygen fuel admission line, join with hydrogen-oxygen fuel generation equipment gas output tube, the other end is provided with at least one hydrogen-oxygen fuel burner port, be provided with safe fire insulation valve in the inside of flame nozzle, described safe fire insulation valve forms ventilative ring-type or sheet labyrinth type fire retarding sheet and back-fire relief sealing gasket by a slice at least with metallic particles die casting to be formed, and metallic particles is preferably stainless steel material.Fire insulation valve is pressed in the flame nozzle with clamp nut, is provided with a connection space between fire insulation valve and the hydrogen-oxygen fuel burner port and constitutes the back-fire relief chamber.In a single day tempering takes place in the use, fire retarding sheet goes out the fire resistance indoor in back-fire relief, because the back-fire relief stroke is short, can not cause any damage to oxyhydrogen combustion equipment during tempering, guarantees the continuity that hydrogen-oxygen fuel burns.The utility model can be widely used in the industrial welding soldering set and chew and pharmaceutical sector peace bottle closure nozzle, and purposes is very extensive.
The utility model is simple in structure, and is easy to install, low cost of manufacture, and security is good, and is of many uses.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Embodiment:
On the multi-functional flame nozzle 1 of hydrogen-oxygen fuel, be provided with hydrogen-oxygen fuel admission line 2, it is to join with nut 3 and hydrogen-oxygen fuel generation equipment gas output tube, hydrogen-oxygen fuel admission line 2 communicates with at least one hydrogen-oxygen fuel burner port 4, on its pipeline that communicates, be provided with fire insulation valve 5, it is made up of five that form with the die casting of stainless steel particle ventilative sheet labyrinth type fire retarding sheets 51 and six back-fire relief sealing gaskets 52, fire insulation valve compresses with clamp nut 6, is provided with a connection space and constitutes back-fire relief chamber 7 between fire insulation valve 5 and hydrogen-oxygen fuel burner port 4.In case as the oxyhydrogen combustion tempering, fire retarding sheet 51 goes out the fire resistance in back-fire relief chamber 7, causes the damage of hydrogen-oxygen fuel generation equipment when avoiding tempering.
Claims (2)
1, a kind of multi-functional flame nozzle that is used for hydrogen-oxygen fuel, it is characterized in that: it is that a end at the flame nozzle is provided with the hydrogen-oxygen fuel admission line, join with hydrogen-oxygen fuel generation equipment gas output tube, the other end is provided with at least one hydrogen-oxygen fuel burner port, be provided with safe fire insulation valve in the inside of flame nozzle, described safe fire insulation valve forms ventilative ring-type or sheet labyrinth type fire retarding sheet and back-fire relief sealing gasket by a slice at least with metallic particles die casting and forms, fire insulation valve is pressed in the flame nozzle with clamp nut, is provided with a connection space between fire insulation valve and the hydrogen-oxygen fuel burner port and constitutes the back-fire relief chamber.
