The oxygen bottle is connected with the oxygen inlet of the cutting gun via an oxygen transmission pipe; the natural gas tank is connected with the natural gas inlet of the cutting gun via the natural gas transmission pipe; an electric gas compressor is arranged above the natural gas tank; the electric gas compressor is provided with a gas inlet pipe and a gas outlet pipe, the gas outlet pipe is connected with the natural gas tank via a check valve; a pressure sensor is arranged on the power supply circuit of the electric gas compressor; the pressure sensor is connected with the natural gas tank; a natural gas output pipe is arranged at the side of the natural gas tank; a pressure reducing valve and a ball valve are arranged in a serial way on the natural gas output pipe; a protective cover is sleeved on the electric gas compressor; a plurality of ventilation gas inlets are arranged at the lower side of the protective cover; and a ventilation pipe is arranged at the top end of the protective cover. According to the natural gas cutting device, acetylene is used for replacing the natural gas to serve as the flammable gas, the device is more environmental-friendly, the use cost is reduced, the natural gas can be acquired conveniently, the flammable gas does not need long-distance transmission, and the use security is improved.
Description
Technical field
The utility model relates to gas cutting device, particularly a kind of natural gas cutting device.
Background technology
Gas cutting is to utilize after fuel gas and combustion-supporting gas mixed combustion, produces thermal-flame and metal material is melted to the method for cutting.Now gas cutting use fuel gas be generally acetylene, fire-retardant gas is oxygen.
Such technology has following deficiency: the production of acetylene and use procedure all can cause comparatively serious pollution to environment, and use cost is higher, and acetylene is all inconvenient as hazardous gas production and transport.
Utility model content
The purpose of this utility model is to provide a kind of natural gas cutting device, uses substitute gas acetylene gas as fuel gas, to make up the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of natural gas cutting device, comprise oxygen cylinder, natural gas tank and burning torch, oxygen cylinder has oxygen conveying pipe to be connected with the oxygen intake of burning torch, natural gas tank has gas delivering pipe to be connected with the gas inlet of burning torch, it is characterized in that: natural gas tank top is provided with electric gas compressor, electric gas compressor has air inlet pipe and escape pipe, escape pipe connects natural gas tank through check-valves, on the power supply circuits of electric gas compressor, there is pressure sensor, pressure sensor connects natural gas tank, Pressure gauge is installed on natural gas tank, there is natural gas efferent duct natural gas tank side, pressure-reducing valve and ball valve have been installed in series on natural gas efferent duct.
As preferably, at electric gas compressor, be set with protective cover outward, protective cover downside has a plurality of fan inlets, and there is exhaust column on protective cover top.
By implementing the utility model, with substitute gas acetylene as fuel gas, make gas cutting environmental protection more, because city is cheap for Gas Prices, can significantly reduce use cost, simultaneously, China's natural gas gas supply conduit network is very universal, to the compression air feed of natural gas tank, can obtain very easily, uses this use novel, do not need fuel gas to carry out long-distance transportation, improved the security of using.The utility model is replaced with welding gun by burning torch and is equally applicable to gas welding.
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
It should be noted that, the present embodiment is a kind of embodiment of the present utility model, is not used in and limits protection domain of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is oxygen cylinder, the 2nd, and ball valve, the 3rd, pressure-reducing valve; the 4th, natural gas efferent duct, the 5th, check-valves, the 6th, natural gas tank; the 7th, electric gas compressor, the 8th, pressure sensor, the 9th, power supply circuits; the 10th, air inlet pipe, the 11st, burning torch, the 12nd, oxygen conveying pipe; the 13rd, gas delivering pipe, the 14th, protective cover, the 15th, Pressure gauge; the 16th, exhaust column, the 17th, fan inlet.
The specific embodiment
A kind of natural gas cutting device, comprise oxygen cylinder 1, natural gas tank 6 and burning torch 11, oxygen cylinder 1 has oxygen conveying pipe 12 to be connected with the oxygen intake of burning torch 11, natural gas tank 6 has gas delivering pipe 13 to be connected with the gas inlet of burning torch 11, it is characterized in that: natural gas tank 6 tops are provided with electric gas compressor 7, electric gas compressor 7 has air inlet pipe 10 and escape pipe 18, escape pipe 18 connects natural gas tank 6 through check-valves 17, on the power supply circuits 9 of electric gas compressor 7, there is pressure sensor 8, pressure sensor 8 connects natural gas tank 6, Pressure gauge 15 is installed on natural gas tank 6, there is natural gas efferent duct 4 natural gas tank 6 sides, pressure-reducing valve 3 and ball valve 2 have been installed in series on natural gas efferent duct 4, outside electric gas compressor 7, be set with protective cover 14, protective cover 14 downsides have a plurality of fan inlets 17, there is exhaust column 16 on protective cover 14 tops.
During use, first natural gas tank 6 is carried out to gas storage, air inlet pipe 10Yu city connects for natural gas, and power supply circuits 9 are electrically connected to city, starts electric gas compressor 7, city is compressed for natural gas, natural gas after compression enters natural gas tank 6 storages through escape pipe 18, check-valves 17, but natural gas air pressure in natural gas tank 6 is while reaching setting value, and pressure sensor 8 disconnects power supply circuits 9, electric gas compressor 7 quits work, and completes gas storage.Open oxygen cylinder 1, ball valve 2, light burning torch 11, can start cutting.Protective cover 14 can protect electric gas compressor 7 by external object, not damaged, and fan inlet 17 and exhaust column 16 coordinate, and can lower the temperature to electric gas compressor 7.When pressure sensor 8 perceives natural gas tank 6 hypotony, restore electricity, electric gas compressor 7 is reworked, again gas storage.If gas cutting working face and city are far away for gas pipeline, also can after gas storage completes, oxygen cylinder 1, natural gas tank 6 and burning torch 11 be moved to working face and carry out gas cutting, air pressure returns to gas storage again when not enough.
