Generate vortex whistle.Meanwhile the air-flow imported above gas bleeder valve also will disperse, then along the first spire 111 and the second spiral shell
Rotation portion 112 smoothly flow to gas outlet 4, prevents air-flow from colliding the secondary generation vortex whistle of gas bleeder valve periphery wall surface.
In present embodiment, arrangement such as Fig. 7 institute of the first spire 111, third spire 113 and the 4th spire 114
Show, the arrangement of the second spire 112, the 5th spire 115 and the 6th spire 116 is as shown in figure 8, here, the first spire
111, third spire 113 and the 4th spire 114 and the second spire 112, the 5th spire 115 and the 6th spire 116
Almost symmetry.Certainly, asymmetric can also respectively be arranged, for example, the position of the first spire 111 and the second spire 112 can be upper and lower
Setting, as long as can smoothly guide the air-flow of top to gas outlet 4.Wherein the structure of each spire can
Think the laminated structure extended spirally, or triangular shape or other structures form.
In addition, those skilled in the art are further appreciated that the flow-guiding structure for guiding air-flow to flow is not limited to
In present embodiment includes the structure type of the first conducting element 117, the second conducting element 118 and each helical element, other
The structure type that air-flow can be guided smoothly to flow can also.
In addition, forming the cylindrical portion 119 extended in the oriented internal cavities, cylinder at air inlet 3 in present embodiment
It is fixed in shape portion 119 for cooperating the sealing structure 14 contacted with spool 2, since valve body 1 generallys use the mode shape of injection molding
At precision cannot cooperatively form sealing, therefore the fixing seal structure 14 in cylindrical portion 119 with spool, it is preferable that this is close
Seal structure 14 is the tubular structure connecting with the inner thread of cylindrical portion 119.It should be understood that cylindrical portion 119 is not
Be it is necessary, cylindrical portion 119 can also be not provided with, herein be arranged cylindrical portion 119 be for more easily fixing seal structure 14.
In addition, being provided with pipe fitting 13 on the wall of the escape pipe at the gas outlet 4 in present embodiment.
As shown in Figure 5 and Figure 6, the inside of the escape pipe at gas outlet 4 is formed as pyramidal structure, the pyramidal structure
Cross section gradually becomes smaller along the direction far from the spool, and pipe fitting 13 is arranged on the internal wall for the pyramidal structure.
Gas bleeder valve in present embodiment is designed when being for the air inlet pipeline system for being applied to engine.?
When piping connection applied to engine, the intercooler air outlet pipe of one end and engine with air inlet 3 is connected, and has
One end of port 4 is connect with air filter air outlet pipe.Pipe fitting 13 is set herein, is logical to connect the crankcase of engine
Air pipe line.Fluid oil in crankcase system can be flowed into the gas bleeder valve by crankcase bleed pipe, be managed by gas outlet 4
The limitation of the pyramidal structure on road, oil may not flow into air filter air outlet pipe, and can slowly accumulate in this along pyramidal structure
In the internal cavities of the valve seat of gas bleeder valve.In this way, high pressure gas is between spool and valve seat in the moment that gas bleeder valve is opened
Gap outflow, the oil liquid of accumulation are dispersed as mist of oil by high pressure gas, and mist of oil enters internal cavities filter escape pipe with gas
It is interior.In this way oil leakage phenomenon can be generated to avoid oil droplet accumulation.
According to another aspect of the present invention, a kind of engine pipelines assembly is also provided, during which includes
Cooler escape pipe, air filter air outlet pipe, crankcase bleed pipe and gas bleeder valve as described above, wherein the gas bleeder valve
Air inlet 3 be connected to intercooler air outlet pipe, gas outlet 4 is connected to air filter air outlet pipe, and pipe fitting 13 and crankcase are logical
Air hose connection.
When driving is anxious slow down and brake, engine throttled back, ICS intercooler system loine pressure is sharply increased, and is anti-
Only middle cooling pipe internal high pressure destroys supercharger impeller, and the gas bleeder valve is opened, and high-speed flow is let out by the gap that gas bleeder valve is opened
Into air filter air outlet pipe.Wherein, gas bleeder valve open when, air-flow in intercooler air outlet pipe from gas bleeder valve into
Port 3 enters, and then fraction brushes upwards under the water conservancy diversion of the first conducting element 117, prevents air-flow blow-through gas bleeder valve
Gas outlet 4；And it impacts the air-flow on the second conducting element 118 and can be directed to and flow downward；It is then channeled to the gas of top
Stream flow to gas outlet 4 along the first spire 111 and the second spire 112, and the air-flow of lower section is along 113 He of third spire
5th spire 115 flows to bottom, then flows upward to gas outlet 4 along the 4th spire 114 and the 6th spire 116.
Gas bleeder valve provided by the invention, by patented product CFD simulation analysis, it can be seen that the gas bleeder valve is in outlet
Substantially without vortex at mouth 4, air flow state is steady, can effectively eliminate vortex noise.Therefore, it is applied to hair in the gas bleeder valve
When in motivation pipe-line system, the NVH performance of vehicle can be effectively promoted.
In addition, gas bleeder valve provided by the present application, is integrated with pipe fitting 13, it is logical crankcase can be connected by the pipe fitting 13
Air hose.Oil gas is mainly engine air gas in the jar burning generation and oil lubricating system lubrication piston in engine crankcase
The gas blowby of generation, these oil gas can enter gas bleeder valve by crankcase ventilation pipeline, the pipeline connected by pipe fitting 13
Wedge structure limitation, the fluid oil in crankcase ventilation system may not flow into air filter air outlet pipe, but slow
Slowly accumulate in the inner cavity of gas bleeder valve bottom, in the moment that gas bleeder valve is opened, high-speed gas can blow on fluid oil and by liquid
Oil is dispersed as mist of oil.Then, mist of oil with air-flow the first conducting element 117, the second conducting element 118 guidance under flow, last edge
Each spire flow to gas outlet 4, wherein when the second conducting element 118 guidance air-flow flows downward, air-flow can brush gas bleeder valve
The oil liquid of bottom makes bottom oil liquid be brushed gas bleeder valve bottom out.To which the fluid oil of preferably gas bleeder valve bottom is dispersed as oil
It is brushed after mist to air filter escape pipe, thereby guarantees that gas handling system, the oil in ICS intercooler system are gaseous state, oil droplet will not be generated
Accumulation guarantees vehicle traffic safety to can avoid gas handling system and ICS intercooler system generation oil leakage phenomenon.
The foregoing is merely better embodiments of the invention, are not intended to limit the invention, all of the invention
Spirit and principle within, any modification, equivalent replacement, improvement and so on, should be included in protection scope of the present invention it
It is interior.
