Abstract
The utility model discloses a cutting torch used for cutting; the outlet of a cutting gas intake pipe on the compound cavity wall is disposed in front of a spray nozzle and the compound cavity wall which is directly over or behind the spray nozzle is added with a cutting gas input pipe to communicate the cutting gas intake pipe and the compound cavity; in this way, the cutting gas can enter the compound cavity through the cutting gas intake pipe and the cutting gas input pipe and be fully mixed with oxygen twice with the attraction of oxygen output from the spray nozzle, and then the mixture of oxygen and cutting gas will be delivered to a cutting nozzle to burn with the attraction of a spraying and suction tube and produce high-temperature fire; the output hole of the spray nozzle has a large diameter and the capability for spraying and suction is strong, which expedites the mixture gas at the cutting nozzle outlet and increases the preheating speed.
Description
Affiliated field
The utility model relates to the torch that is used to cut, especially a kind of cutting torch that is used for gas cutting.
Background technology
Gas cutting is to utilize the effect of oxygen-Cutting Gas neutral flame high temperature that produces and the air-flow that exceeds the speed limit that the metal that is cut is preheating to ignition temperature, pass to the hyperbaric oxygen air-flow in preheating place then, metal is burnt in pure oxygen emit a large amount of heat, and borrow the pressure of hyperbaric oxygen air-flow that the oxide that incision forms is blown away, bulk metal is promptly severed.Now used cutting torch is mainly by handle, cutting torch, oxygen hose, cutting tracheae, mixing chamber, be positioned on the handle oxygen inlet pipe that is communicated with oxygen hose and mixing chamber and be communicated with the Cutting Gas inlet pipe that cuts tracheae and mixing chamber, the Cutting Gas control valve of adjusting Cutting Gas input, cutting oxygen pipe, the cutting oxygen valve and the oxygen regulating valve of control oxygen output quantity, be installed on the nozzle in the mixing chamber, be positioned at the injecting tube of mixing chamber's outlet, the mixing tube that is communicated with cutting torch and injecting tube is formed.In the work, oxygen enters mixing chamber through oxygen hose, oxygen inlet pipe, oxygen regulating valve, nozzle, Cutting Gas enters mixing chamber through cutting tracheae, Cutting Gas control valve, Cutting Gas inlet pipe, the Cutting Gas of low pressure is delivered to the metal that the burning preheating of cutting torch place is cut after hasty the mixing in injecting tube is delivered to mixing tube under the attraction of the oxygen of nozzle equipped at outlet port output.Exist Cutting Gas and oxygen and can not fully mix and just be transported to the burning of torch head place, do not reach the highest flame temperature, cause the preheating speed slow; Present in addition used cutting torch be positioned at the delivery outlet aperture of nozzle of mixing chamber narrow and small (＜0.9mm), it is low to penetrate energy-absorbing power, causes the mist flow velocity in cutting torch exit low, also is a reason that causes the preheating speed slow.
Summary of the invention
Can not fully mix with oxygen and cause flame temperature low in order to overcome existing cutting torch Cutting Gas with regard to burning, the low low deficiency of mist flow velocity in cutting torch exit that causes of preheating speed's energy-absorbing power of penetrating slow and nozzle, the utility model provides a kind of cutting torch, the Cutting Gas of this cutting torch can fully be mixed with oxygen, burning produces the flame temperature height, and the energy-absorbing power of penetrating of nozzle is strong, makes the mist flow velocity in cutting torch exit fast, preheating time is short, high efficiency.
The technical scheme that the utility model technical solution problem is adopted is: the gas outlet that is communicated with the Cutting Gas inlet pipe of cutting tracheae and mixing chamber is positioned on mixing chamber's locular wall in the place ahead on the nozzle, mixing chamber's locular wall at directly over the corresponding nozzle delivery outlet or rear also is provided with the Cutting Gas input pipe that is communicated with Cutting Gas inlet pipe and mixing chamber, and the nozzle delivery outlet adopts the aperture that enlarges.The utility model is arranged at the place ahead on the nozzle with the gas outlet of the Cutting Gas inlet pipe on the hybrid chamber locular wall, and directly over the nozzle delivery outlet or mixing chamber's locular wall at rear set up the Cutting Gas input pipe that is communicated with Cutting Gas inlet pipe and mixing chamber, make Cutting Gas enter mixing chamber respectively by Cutting Gas inlet pipe and Cutting Gas input pipe respectively, under the attraction of nozzle equipped at outlet port output oxygen, secondary fully mixes with oxygen, inhale to penetrate by injecting tube and deliver to the burning of cutting torch place, flame temperature height through mixture pipe; The aperture that the nozzle delivery outlet adopt to enlarge, it is strong to penetrate energy-absorbing power, makes the mist flow velocity height in cutting torch exit, and shorten preheating time.
The beneficial effects of the utility model are, the gas flow rate height that cutting torch penetrates, and gas combustion is abundant, and the flame temperature height of generation has improved the metal preheating speed.
