Abstract
The utility model relates to a metal cutting torch capable of using various kinds of gas and liquid fuel. The utility model uses gas and liquid fuel to substitute for acetylene gas, and the utility model can obtain materials locally, which saves the cost. The cutting torch is composed of a filtering core, a regulating valve, an outer cutting nozzle, an inner cutting nozzle, a flow deflection barrel, etc. Liquid fuel is conveyed from a fuel pot to the cutting torch, and the fuel is deflected and gasified in an annular groove by high temperature when the outer cutting nozzle works. Oxygen and gasified fuel are mixed and sprayed to be burned to carry out cutting, heating, etc. The utility model which works for a long time does not scald hands. The cutting torch adopts the traditional control habit and the operating mode, and people do not need to be specially trained and can operate the cutting torch. The use is safe, and the utility model has no tempering trouble.
Description
The utility model is a kind of Metal Cutting torch, and it can use multiple gas, liquid fuel to carry out Metal Cutting, hot melt, heated baking etc.Belong to metal solder equipment field.Being widely used for the processing and manufacturing of plant equipment etc., is factories and miness, enterprise and the indispensable important tool of metal processing manufacturing industry.
The Metal Cutting torch of Shi Yonging in the prior art generally is to serve as the cutting energy with oxygen and acetylene gas, and it is made up of oxygen cylinder, acetylene cylinder, airline hose and cutting torch.Small part user scene is the electricity consumption acetylene gas of getting made of stones still, not only dangerous big but also contaminated environment.General problem is to use the cost height, and volume is big and heavy.Remote districts acetylene gas source inconvenience.
The purpose of this utility model is a kind of Metal Cutting torch that uses multiple gas, liquid fuel that designs for the deficiency that overcomes existing oxy-acetylene cutting.As natural gas, liquefied gas, metal welding/cutting gas, light oil, gasoline, kerosene, diesel oil and other combustible gases, liquid medium, all can use as the cutting energy.Suit measures to local conditions to gather materials on the spot, the high acetylene gas of displacement cost easily is to reduce use cost.
The new purpose of this practicality can be achieved through the following technical solutions: it is crossed filter core, gas liquid fuel control valve, gas-liquid conduit, cleavage block, interior cutting torch, baffling tube and outer cutting torch etc. by handle and forms.Oxygen is entered arm and handle front stall on the handle of cutting torch through airline hose by oxygen cylinder, oxygen is divided into two the tunnel, the one tunnel within it behind the cutting oxygen valve, with conduit enter cleavage block and in cutting torch, ejection high pressure oxygen cuts metal; Another road oxygen is regulated the back through control valve and is entered with conduit in the annular space that cleavage block, outer cutting torch and interior cutting torch form, and the interface between cutting torch and the cleavage block outside mixes mutually with fuel after the vaporization, sprays and burns; Liquid fuel enters handle back seat joint by the low-pressure fuel jar through conveying rubber pipe, enter cleavage block through filter core, fuel control valve, conduit again, baffling tube baffling in the cutting head cannelure absorbs the tip heat and makes liquid fuel evaporation again, mix mutually in cutting torch and the annular space that interior cutting torch is formed outside after the vaporization, burning produces high-temperature gas the metal of desire cutting is heated.Liquid fuel cutting torch outside is interior tortuous circuitous, and the temperature when borrowing outer cutting torch self work first makes liquid fuel evaporation, second can reduce the temperature of outer cutting torch, a cooling effect.When selecting gaseous fuel for use, gas gives the direct and oxygen mix burning in heat back by the baffling tube, produces high-temperature gas, and can improve efficiency of combustion, metal is cut or toasts, hot melt etc.
This Metal Cutting torch can use multiple gas, liquid fuel to do the energy.According to measuring and calculating, when every cutting torch cut with the gasoline replace ethine, annual every Metal Cutting torch can be saved about 60,000 yuan, if promote the use of in the whole nation, it will be bigger saving number, and social benefit is more remarkable.If suit measures to local conditions to adopt gas-liquid fuel, reduction effect is more obvious.Above-mentioned lease acetylene gas bottle and the freight of also not comprising.Applying unit is gathered materials on the spot, and can save a large amount of expenses, and In-particular is just much convenient with outlying isolated area.As long as possess one of above-mentioned several energy, save and purchase acetylene gas, lease acetylene cylinder, expenses such as transportation.
This Metal Cutting torch adopts the grasp custom and the mode of operation of spreading, and needn't special training can skillfully operate the sorrow that does not have tempering safe in utilization.
This cutting torch structure adopts the self-heating gasifying mode, and the fuel that enters is first given the heat vaporization.Second can effectively reduce the temperature of cutting torch, work long hours, can not cause the hot and tempering problem of cutting torch heating.With the matching used low-pressure fuel jar of Metal Cutting torch, be exclusively used in storage and charge, and fuel is transferred to the Metal Cutting torch, and dispose the pressure limiting inflator, oil filler, safety valve, liquid valve etc. with certain pressure.
Application below in conjunction with 1 pair of this utility model of accompanying drawing simply shows with calcspar earlier, and then describes in further detail with accompanying drawing 2 and 3 pairs of practical new works of accompanying drawing.In the accompanying drawing 1,1, low-pressure fuel jar 2, oxygen cylinder

2 pairs of Metal Cutting torches are described further in conjunction with the accompanying drawings: oxygen enters going up of handle back seat (12) and handle pipe (11) from joint (15) and manages, and after control valve (17) enters conduit (6), this is after cleavage block (3) enters interior cutting torch (2); Liquid fuel enters the following pipe of handle pipe (11) through filter core (13) from joint (14), enter conduit (7) through control valve (10) again and enter cleavage block (3) then, after this enter in the cannelure of cutting head (1), vaporization after the heat absorption of baffling tube (4) baffling in cannelure, fuel after the vaporization enters by in the annular space between inner nozzle (2) and the outer cutting torch (1) through the gap on outer cutting torch top, meet with oxygen and mix at this, the ejection burning, produce high-temperature gas, with to desiring cutting metal heating etc.
3 pairs of low-pressure fuel jars are described further in conjunction with the accompanying drawings: (1) is tank body among the figure, liquid fuel adds from adding inlet (6), guard (7) is with fuel filter after filtration, and complete back pressurizes, forces fuel to flow to the Metal Cutting torch through drain pipe (8) and fuel outlet valve (4) by pressure limiting inflator (2).Pressure limiting inflator (2) will show pneumatic tube piston rod (3) to make hollow form for limiting maximum working pressure, forming clearance volume, because the existence of clearance volume, can be conveniently under the pressure of setting inflate pressurization for fuel tank.But limit pressure if be higher than this, the gas in the clearance expands when piston is air-breathing, forms expansion → compression → expansion ... gas can't be pressed in the jar, guarantee tank body safety within limits thereby limit pressure.Safety valve (5) is to cause overpressure protection apparatus for preventing because of reasons such as temperature rises.
