Description
Technical field
The utility model relates to a kind of device that the compressed natural gas improvement is cut gas for metal.
Background technology
Therefore the combustion gas that Metal Cutting is used is generally acetylene, because that compressed natural gas is used in daily life is more extensive, is used for the Metal Cutting combustion gas with substitute gas acetylene, no matter from fuel source, or aspect such as use cost, more practical and convenient.But; If compressed natural gas decompression back flows to the overlong time that welding torch is used for cutting metal through pipeline, owing to will absorb a large amount of heats after the natural gas decompression, then pipeline external surface freezes easily; Pressure-reducing valve on the pipeline is worked for a long time at low temperatures, more is prone to cause damage.In addition, natural gas is if directly be used for welding torch burning, and flame temperature is relatively low, then causes cutting speed slow and gas usage is big; Need be with sneaking into fuel gas additives in the natural gas, so that the flame temperature of natural gas is higher.Based on above-mentioned reality, be necessary very much to design a kind of natural gas improved device.
Summary of the invention
The technical problem that the utility model will solve provides a kind of device that the compressed natural gas improvement is cut gas for metal.
In order to solve the problems of the technologies described above, the utility model provided cuts the device of gas with the compressed natural gas improvement for metal, and its structure comprises the heater that can be communicated with the compressed natural gas source and the gas agent blending tank that can natural gas be mixed with fuel gas additives; Heater is communicated with gas agent blending tank through depressurized system.
Said depressurized system comprises inlet plenum, middle gas chamber and discharge chamber; Inlet plenum is communicated with heater through the one-level relief line, and middle gas chamber is communicated with inlet plenum through air delivering pipeline, and discharge chamber is communicated with middle gas chamber through the second depressurized pipeline, and gas agent blending tank is communicated with discharge chamber through outlet pipe.
Said one-level relief line is two that parallel connection is provided with.
Said one-level relief line is identical with the second depressurized pipeline structure, all comprises tracheae and is serially connected in the pressure-reducing valve on the tracheae.
Crossing on the tracheae of said second depressurized pipeline is serially connected with the flowmeter between pressure-reducing valve and discharge chamber.
But said heater comprises the heating cabinet of splendid attire water, and heating cabinet is provided with air inlet that can be communicated with the compressed natural gas source and the gas outlet that is communicated with depressurized system, the coil pipe that is provided with electric calorifie installation in the heating cabinet and is communicated with air inlet and gas outlet.
The utility model only is made up of heater, gentle dose of blending tank three parts of depressurized system, thereby simple in structure; Being provided with of heater solved air delivering pipeline and frozen and the pressure-reducing valve low temperature problem damaged easily of work down; The mixing that is arranged so that natural gas and fuel gas additives of gas agent blending tank becomes and is more prone to.
In sum, the advantage of the utility model be simple in structure, easy to use, cost of manufacture is low; Can bring the beneficial effect of pressure-reducing valve long service life.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
