Abstract
The utility model relates to a vaporizing type cutting tip. A center core and a tail seat are fixedly connected. The axial direction of the tail seat and the axial direction of the center core are provided with oxygen via holes. A housing outside the center core and the tail seat are fixedly arranged, and a labyrinth type clearance is arranged between the center core and the housing. A via hole which is communicated with the clearance is arranged on the tail seat. The utility model uses kerosene, etc. to generate burnable vapour. When the utility model works, after the burnable vapour is ignited on a nozzle, the burnable vapour which is filled whereafter is preheated in the labyrinth type clearance and is mixed with oxygen for generating flames with high temperature. In the utility model, kerosene vapour is used for replacing acetylene gas for reducing production cost, and the production cost of the utility model is one tenth of that of a vaporizing type cutting tip which uses the acetylene gas. simultaneously, pollution on the atmospheric air is reduced.
Description
The utility model is a kind of instrument that metal or other material are carried out the flame cutting, particularly a kind ofly is used for the evaporation type cutting torch that oily steam cutting cuts.
The gas that is used for the gas flame cutting at present is acetylene gas mostly, though acetylene gas can produce higher temperature, but can cause the pollution to atmosphere in its production process, simultaneously the production cost of acetylene gas is than higher, correspondingly makes that the expense of cutting processing is higher.
The purpose of this utility model provides a kind of novel vapour and cuts apparatus, and it can overcome existing shortcoming in the prior art, reduces atmosphere pollution, and reduces production costs.
The purpose of this utility model is achieved in that it comprises tailstock, it is characterized in that SMIS fixedlys connected with tailstock, axially have an oxygen through hole at tailstock and SMIS, SMIS has a shell and tailstock fixed installation outward, between SMIS and the shell labyrinth gap is arranged, have through hole on the tailstock and communicate with this gap.
The flammable gas that the utility model uses kerosene, gasoline, light diesel fuel etc. to produce, during work, oxygen is fed by the tailstock centre bore, by anterior nozzle ejection, flammable gas is fed by aperture around the tailstock, after the ejection of nozzle place is lighted, makes the flammable gas that feeds subsequently preheated in labyrinth gap, generate flame with oxygen mix, temperature can reach 2600-2700 ℃.The utility model is with oily vapour replaced acetylene gas, and the cost of oily vapour is lower than acetylene gas, and institute only is to use 1/10th of acetylene gas so that cutting cost reduces, and has reduced the pollution to atmosphere simultaneously.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is a structure cutaway view of the present utility model.
It among the figure tailstock, the 2nd, shell, the 3rd, SMIS, 4 and 5 is shading rings, shown in figure, be threaded between tailstock and the SMIS, center at tailstock and SMIS has axially extending bore, it is the oxygen through hole, and shell is fixedly mounted on the tailstock, leaves the gap between shell and the SMIS, having aperture on tailstock communicates with this gap, near the spout place, the gap between shell and the SMIS is mounted respectively at shading ring on the SMIS 4 and the shading ring 5 that is installed on the shell and is separated into labyrinth type, makes flammable gas obtain sufficient preheating through this labyrinth gap the time.
