Abstract
The utility model relates to an industrial gas quick cutting nozzle for cutting a metal material. The cutting nozzle is characterized by consisting of a cutting nozzle main body, a spiral mixer, a cutting nozzle jacket, a cutting nozzle inner nozzle and a connecting rod, wherein one end of the cutting nozzle inner nozzle is connected with the connecting rod through an internal thread; the other end of the connecting rod is connected with the cutting nozzle main body through an external thread; the spiral mixer is arranged at the thread of the connecting rod; the cutting nozzle jacket is arranged outside the spiral mixer; 10 to 20 tooth groove gas channels are formed on the cutting nozzle inner nozzle; a spray pipe pore channel is a streamline Laval pore channel and consists of a stabilization section, a contraction section, a throat part and a diffusion section; and surface electroplating is performed in the streamline pore channel. The industrial gas quick cutting nozzle is applied to a flame cutting machine, can achieve a smooth cutting surface and a high cutting speed and avoid undercut, burn-damage, adhering slag, recarburizing and hardening when used for cutting steel, and has long service life.
Description
Technical field
The utility model relates to a kind of burner of burning gases fuel, particularly relates to the industrial combustion gas divergent bore nozzle that a kind of cutting metal material is used.
Background technology
Domestic at present, traditional cutting to ferrous metal is to adopt flame combustion gas cutting head through the cutting of oxy-acetylene gas flame in steel and iron industry, and this oxy-acetylene gas flame cutting exists: problems such as cost height, poor stability, environmental pollution.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence; Purpose provide industrial combustion gas such as a kind of employing petroleum gas resource natural gas, propane, propylene be raw material replace ethine gas to the ferrous metal fly-cutting, realize the industrial combustion gas divergent bore nozzle of energy-saving and environmental protection, safety.
The utility model industrial combustion gas divergent bore nozzle content Description:
The utility model industrial combustion gas divergent bore nozzle; It is characterized in that: form by mouth and connecting rod in cutting torch main body, ribbon mixer, cutting torch overcoat, the cutting torch; An end of mouth is connected with connecting rod through internal thread in the cutting torch; The other end of connecting rod is connected with the cutting torch main body through external screw thread, is provided with ribbon mixer at the screw thread place of connecting rod, and the outside is provided with the cutting torch overcoat.
In cutting torch, be provided with 10～20 teeth groove shape blast tubes on the mouth, the jet pipe duct is duct, fairshaped Lavalle, is made up of stable section, contraction section, throat, diffuser four parts, in fairshaped duct, adopts electroplating surface to handle.
The utility model industrial combustion gas divergent bore nozzle is applied on the flame cutting machine, can realize that to steel cutting cut surface is smooth, cutting speed fast, no undercut burns down and hangs slag, no carburetting and hardening phenomenon, cutting torch long service life.
Description of drawings
Fig. 1 is an industrial combustion gas divergent bore nozzle structural representation
Among the figure: the 1st, cutting torch main body, the 2nd, ribbon mixer, the 3rd, mouth, the 5th in the cutting torch overcoat, the 4th, cutting torch, connecting rod.
The specific embodiment
The utility model industrial combustion gas divergent bore nozzle is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1; The industrial combustion gas divergent bore nozzle; By: mouth 4 and connecting rod 5 are formed in cutting torch main body 1, ribbon mixer 2, cutting torch overcoat 3, the cutting torch, and an end of mouth 4 is connected with connecting rod 5 through internal thread in the cutting torch, and the other end of connecting rod 5 is connected with cutting torch main body 1 through external screw thread; Screw thread place at connecting rod 5 is provided with ribbon mixer 2, and the outside is provided with cutting torch overcoat 3.In cutting torch, be provided with 10～20 teeth groove shape blast tubes on the mouth 4, the jet pipe duct is duct, fairshaped Lavalle, is made up of stable section, contraction section, throat, diffuser four parts, in fairshaped duct, adopts electroplating surface to handle.
During use; Adopt infant industry combustion gas such as natural gas, propane, propylene to get in the cutting torch by the air admission hole of cutting torch main body 1 side; Preheated oxygen is got in the cutting torch by the air admission hole of cutting torch main body 1 side simultaneously; After ribbon mixer 2 abundant mixing, through the teeth groove blast tube ejection burning preheating steel plate of mouth in the cutting torch 4.Cutting oxygen is got into by cutting torch main body 1 centre bore, through the fairshaped Laval nozzle duct on the mouth in the cutting torch 4, with the supersonic speed Oxygen Flow steel plate is implemented cutting; Fairshaped Laval nozzle duct is that the less airflow design of resistance forms in the employing aerodynamics, is non-entity shape chamber, is divided into stable section, contraction section, throat, diffuser four parts; Resistance is less when the Oxygen Flow passing hole channel, and length increases, and cylindricity improves; It is more concentrated to reach cutting oxygen stream; The purpose that penetration power is stronger adopts electroplating surface to handle in the streamlined duct, improved the anti-wear performance in streamlined duct; Reflect the heat of part surface of steel plate radiation, prolonged the service life of cutting torch.
