Jet-attract form gasoline cutting torch

Abstract

The invention relates to a jet-attract form petrol cutting torch, comprising: one end of connecting pipe is small cylinder while another one is large cylinder; the end of cylinder has a groove while an inner cylinder surface in the middle; the jet-attract pipe shaped in cylinder has a hollow pipe in the middle, and one end of it is external pyramidal face while another end is inner pyramidal face, and its position for the hollow pipe is inner pyramidal face while the external round on another end is cylinder face, furthermore, an oil hole is mounted on its pipewall; the nozzle shaped in cylinder has a hollow in the middle, while the external round on its one end is external pyramidal face while another one is cylinder, and the position of hollow pipes are inner pyramidal face; the oil noodle shape in cylinder staff has a pyramidal face shaped end. The inner pyramidal face of hollow pipe on one end of the jet-attract pipe is connected to the external round of one end of the nozzle. And the connecting pipe covers one end of nozzle that has inner pyramidal face on the position of hollow pipe, which contains an oil noodle whose external pyramidal end towards the nozzle and the left end of noodle is the mixed oxygen valve post, while the mixed oxygen valve post fixed on the noodle. Said invention has high cutting speed of cutting torch and better quality.

Problems solved by technology

[0002] At present, among the existing metal cutting torches, acetylene cutting torch guns are widely used, which have many disadvantages in terms of energy saving, environmental protection, safety, transportation, etc., and their use is gradually restricted.

Now there are jet-suction cutting torches on the market. Because the atomization principle of the cutting torch is not considered in the design, the design parts and internal parts are not well matched, which directly affects the performance of the cutting torch, whether it is on the flame, There are deficiencies in atomization

For example, the Chinese Patent Office has disclosed a patent for a "jet-suction gasoline cutting torch". Oxygen valve, connecting pipe joints, gasoline passage, oxygen passage connected to the injection and suction part. The structure is that the injection and suction part is in the middle of the cutting torch. The distance between the part and the cutting nozzle is long, and the internal space is large. During the process of gasoline being injected into the precursor by oxygen, the oil gradually diffuses, so that the advantage of the injection suction is not really exerted, which reduces the injection and absorption ability and makes the atomization After that, the gasoline becomes liquid again, and flows to the cutting nozzle of the precursor in liquid state.

In addition, the cutting torch generally works vertically, and the oil returns to a liquid state at the front end of the injection chamber. If it cannot flow out uniformly, it will cause poor atomization, oil dripping, unstable flame, and low combustion value, which directly affect the cutting speed and are not conducive to Adjustment
