Abstract
The utility model discloses a dual-purpose welding and cutting spray gun. The spray gun comprises a nozzle, a mixed gas pipe, an oxygen pipe, a first oxygen control valve, a mixed gas control valve, oxygen inlets, an acetylene inlet and a gas mixing zone, wherein two oxygen inlets are provided, one is connected with the oxygen pipe through the first oxygen control valve, and the other directly enters the gas mixing zone; the gas mixing zone is also connected with the acetylene inlet and the mixed gas control valve; the other end of the mixed gas control valve is connected with the mixed gas pipe; and the other end of the mixed gas pipe and the oxygen pipe are hinged with the nozzle. The dual-purpose welding and cutting spray gun is characterized by further comprising a second oxygen control valve mounted at the inlet from which oxygen enters the mixed gas pipe. The quantity of oxygen entering the mixed gas pipe can be controlled through adjusting the second oxygen control valve at the inlet of the mixed gas pipe, so as to control the proportion of acetylene and oxygen in the mixed gas, when the first oxygen control valve at the inlet of the oxygen pipe is closed, and then the second oxygen control valve at the inlet of the mixed gas pipe is adjusted, the proportion of the mixed gas can be suitable for gas welding.
Description
Technical field
The utility model relates to gas welding, gas cutting device, the dual-purpose spray gun of particularly a kind of welding.
Background technology
In commercial production, many products all need utilize oxygen and mesolow acetylene as thermal source, weld or preheating ferrous metal or non-ferrous metal workpiece; After also having many product needed to utilize gas that the work piece cut place is preheating to uniform temperature, ejection high-speed cutting oxygen flow makes material combustion and exothermic mode realize cutting.In the market, welding is employed with gas cutting is two kinds of different equipment.What welding was used is welding torch, and the effect of welding torch is that fuel gas and oxygen are mixed by a certain percentage equably, sprays from tip with certain speed, forms the flame of certain energy rate, certain ingredients, suitable welding requirements and smooth combustion; What gas cutting used is cutting torch, and two pipelines of oxygen and acetylene are arranged on it, utilizes the mist of oxygen and mesolow acetylene and the flame heat energy of pure oxygen to realize cutter.Except gas cutting also needs pure oxygen, the employed mixed gas composition of gas welding and gas cutting all is oxygen and acetylene, and just for no other reason than that the ratio of two kinds of gases in mist is different, and factory will purchase two kinds of equipment, and this has improved the cost of factory greatly.
The utility model content
The purpose of the utility model is in order to solve the high problem of above-mentioned factory cost, provide a kind of can gas welding again can gas cutting the dual-purpose spray gun of welding.
For this reason, the technical scheme that the utility model adopted is: the dual-purpose spray gun of welding comprises shower nozzle, gas mixing pipe, oxygen hose, the first oxygen control valve door, mist by-pass valve control, oxygen inlet, acetylene import, gas mixing zone; Oxygen inlet is divided into two-way; The first oxygen control valve door of leading up to connects oxygen hose, and another road directly gets into gas mixing zone, and gas mixing zone also connects acetylene import and mist by-pass valve control; The other end of mist by-pass valve control connects gas mixing pipe; The other end and the oxygen hose of gas mixing pipe meet at shower nozzle, it is characterized in that: the dual-purpose spray gun of described welding also has one second oxygen control valve door, and it is installed in the import department that oxygen gets into gas mixing zone.
In the prior art; The equipment that is used for gas cutting has only an oxygen control valve door in oxygen hose import department; There is not the import department of oxygen control valve door at gas mixing zone; So can not change the ratio of interior oxygen of gas mixing pipe and acetylene, can only make mist be fit to gas cutting, and can't be used for gas welding.The oxygen control valve door of the utility model has two, and one is the first oxygen control valve door that gets into oxygen hose import department at oxygen, and another is the second oxygen control valve door that gets into gas mixing zone import department at oxygen; The second oxygen control valve door can be controlled the number that oxygen gets into gas mixing zone, the ratio of acetylene and oxygen from what control mist; When the dual-purpose spray gun of welding was wanted to be used for gas welding, as long as close the first oxygen control valve door of oxygen hose import department, the second oxygen control valve door of adjustments of gas mixed zone import department made the ratio of mist be fit to gas welding just again.
The benefit of the utility model is to reach gas welding and two kinds of effects of gas cutting with a kind of equipment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure diagram.
The specific embodiment
Present embodiment comprises shower nozzle 1, gas mixing pipe 2, oxygen hose 3, mist by-pass valve control 4, the first oxygen control valve door 51, the second oxygen control valve door 52, oxygen inlet port 6, acetylene inlet port 7, mixed zone 8.
During the present embodiment gas cutting; Oxygen and acetylene get into from oxygen inlet port 6 and acetylene inlet port 7 respectively; Oxygen is divided into two-way; The first oxygen control valve door 51 of leading up to gets into oxygen hose 3, and mix with acetylene through mist by-pass valve control 4 entering gas mixing pipes 2 through the second oxygen control valve door, 52 entering mixed zones 8 on another road; Regulate the second oxygen control valve door 52 and can control the ratio of acetylene and oxygen in the mist, make this ratio be fit to gas cutting.
During the present embodiment gas welding; Oxygen and acetylene get into from oxygen inlet port 6 and acetylene inlet port 7 respectively; Close the first oxygen control valve door 51, oxygen is all mixed with acetylene through mist by-pass valve control 4 through the second oxygen control valve door, 52 entering mixed zones 8 get into gas mixing pipe 2; Regulate the second oxygen control valve door 52 and can control the ratio of acetylene and oxygen in the mist, make this ratio be fit to gas welding.
