Description

Air inlet recycling pipe fitting with circuit chamber
Technical field
The present invention relates to a kind of air inlet with circuit chamber to recycle pipe fitting, belongs to gas recirculation system field.
Background technology
Circuit tube assembly is assemblied on gas engine between mixed gas admission line and booster, be booster before it is last One section of pipe fitting, i.e. mixed gas are by being directly entered the compressor impeller of booster after this section of pipe fitting.
Traditional gas engine, gas handling system using air inlet recycling form, i.e., mixed gas by charge inter cooling after, bypass One gas circulates air inlet before returning to booster.The existing tracheae part that is recycled into welds special-shaped t-bend pipe for a section, and air inlet is again Before recyclegas is passed directly to booster, in this way, the air-flow with certain pressure gets to booster by sprue is imported On compressor impeller, the angle that air-flow enters impeller can change with pressure, be different from the inducer guide effect of impeller Design load, increases shock of the air-flow to impeller, influences the work efficiency of impeller, meanwhile, there is the air-flow compared with strong pressure to beat Being vibrated on impeller, caused by shock also can be abnormal, and impeller is high speed revolving part, and long-term accumulated can produce bad shadow to booster Ring.
The content of the invention
To solve above technical problem, the present invention provides a kind of air inlet recycling pipe fitting with circuit chamber, makes recycling gas Body is after internal passage is depressurized, then imports in sprue, avoids air inlet from recycling gas bad shadow caused by impeller Ring, ensure that the normal work of booster and the normal air inlet of gas engine.
Its technical solution is as follows:
A kind of air inlet recycling pipe fitting with circuit chamber, including main pipeline, the main pipeline outer sheath be equipped with the first circuit and Second circuit, forms the first circuit chamber and the second circuit chamber between first circuit and the second circuit and main pipeline, and described first Connected between circuit and the second circuit by ring flat-plate, circumferentially a circle is evenly arranged with recirculation hole, the main pipeline on the ring flat-plate The annular groove communicated with the second circuit chamber is additionally provided with side wall, the first circuit outside vertical is provided with air inlet pipe, should be into Tracheae is connected with the first circuit chamber.Circuit tube assembly uses the pressure reduction structure of two-stage circuit chamber side by side, compact-sized, is depressurizing While reduce windage loss, prevent recycling gas import sprue after, due to recycle gas pressure with import angle Harmful effect is caused to the work efficiency of pressure booster blower impeller.
Preferably, first circuit and the second circuit are built outside sprue, and diameter is identical, the first circuit Length is more than the length of the second circuit.It is so designed that, circulating air can be made smoothly to enter the second circuit chamber from the first circuit chamber, Realize two-stage decompression step by step, avoid the collision to compressor impeller, at the same ensure that sprue latus rectum enough and air pressure stabilization.
Preferably, first circuit and the second circuit are connected with main pipeline with welding manner.Manufacture easy to produce, and Production cycle is shorter, cost is relatively low.
Preferably, the air inlet pipe and the first circuit are smooth circular sliding slopes.Be so designed that, ensure that air inlet pipe into Gas is unobstructed.
Beneficial effect:
Above technical scheme with circuit chamber air inlet recycling pipe fitting, devise build outside sprue to air-flow The first circuit chamber and the second circuit chamber with depressurization, both ensure that the normal flow area and flow channel shape of sprue, Airflow collision loss is reduced while depressurization is played to recycling gas, recycling gas is avoided and imports mainstream Due to recycling pressure harmful effect and to sprue caused by the work efficiency of pressure booster blower impeller of gas behind road The flow-disturbing of gas influences, and improves the working life of booster, has ensured that sprue air inlet is unobstructed, easily fabricated, and cost it is low, It is with short production cycle.
Brief description of the drawings
Fig. 1 the structural representation of present invention.
