Technical field
The present invention relates to two-fluid convergence or separation technology field, more particularly to a kind of two-fluid concentric tube and non-concentric pipe
Switching device.
Background technology
It is most common to be cooled down using cutting fluid at present in intermetallic composite coating cooling system, i.e., by low-lift pump cutting fluid
It squeezes into pipeline, is flowed out from nozzle by valve, nozzle is mounted on close to the position of cutting zone, after cutting fluid flows through cutting region
It then flows on the different components of lathe, is then pooled in draw-off tray, then flow back into cutting liquid case from draw-off tray, cycle makes
With.
In order to reduce the frictional force between cutter and workpiece, reduce when cutter shears workpiece and caused by friction of workpiece
Heat usually will rush at cutter, to wash away chip using a large amount of cutting fluid.The flow of cutting fluid is big just to make cutter and work
Part is cut liquid and is flooded.A large amount of cutting fluid is serious using environmental pollution, and cost is again high, moreover, a large amount of cutting fluids use
Niff can be manufactured in machining area.
In order to overcome the above problem, occurs a kind of low-temperature trace lubrication technology in the prior art, i.e., by low temperature compression sky
For gas with after micro lubricating fluid mixed aerosol, injection to machining area implements cooling and lubrication to processing district.Different micro profits
Lubricating oil mist device mixed aerosol formed mist of oil before, need the input form of fluid and high pressure gas different, some need by
Fluid and high pressure gas are transported to atomizer in concentric fashion by concentric pipe, some then need independently separated fluid pipe
Road and gas pipeline, therefore, different micro lubricating mist of oil devices are low with the suitability of fluid, gas supply device.

Preferably, it is connected with cylinder cap at the top of the cylinder body, there is sealing caulking groove at the top of the cylinder body.
Preferably, the cylinder base extends outward to form fixed bottom plate, and the fixed bottom plate has fixed slot.
Advantageous effect：With non-concentric pipe switching device, high pressure gas enters this two-fluid concentric tube by admission line
In inner chamber of cylinder block, fluid is carried through cylinder body flow direction connection nozzle through inflow pipeline, due between connection nozzle and inflow pipeline
There are annular gap, the high pressure gas for being located at inner chamber of cylinder block flows to connection nozzle through annular gap so that high pressure gas and fluid
Converge output outward with one heart at connection nozzle, by the device, the inflow pipeline and air inlet pipe of non-concentric arrangement may be implemented
Road is converted concentric oil-gas pipeline and is exported outward, to meet difference of the different micro lubricating mist of oil devices to fluid, gas
The requirement of input form, is effectively reduced cost.Certainly, by the switching device, concentric oil-gas pipeline can be also converted to
Nonconcentric(al) oil pipe and tracheae, and then outside conveying high-pressure gas and lubricating oil respectively.
