The invention discloses that a kind of malleation indentation type for turbocharger is exitted and regulate valve system, including being arranged on the upper cover on top and being arranged on the lower cover of bottom；The side of described lower cover is provided with valve, is provided with main film, is provided with compression spring between said primary membrane sheet and described upper cover between described upper cover and lower cover；The upper end of described compression spring is socketed on the recess that described upper cover is formed down, and its lower end is connected on the bracket that said primary membrane sheet is formed；Also include being arranged on the valve rod bottom described lower cover, be connected in the upper end of described valve rod extend into described lower cover and through said primary membrane sheet and described compression spring are fixing.The present invention is to utilize malleation indentation type venting regulation valve in turbocharger to control the nozzle ring of variable area turbocharger, to so there is no need to the negative pressure device of outside, and it is simple that it has compact conformation, the advantage of reliable operation.
Description
Technical field
The present invention relates to a kind of malleation indentation type venting regulation valve system for turbocharger.
Background technology
At present, the vent valve of turbocharger, is one of the important spare part of turbocharger.Primarily serve control
The effect of turbo charger speed processed.The vent valve of current turbocharger mainly has two types.One is
Malleation stretches out type, and one is negative pressure indentation type.
Wherein, malleation stretches out the compressed air that type type vent valve produces mainly by turbocharger self, comes
Drive the movement of vent valve valve rod, be mainly used in common bypass gas escape type turbocharger.As it is shown in figure 1,
This malleation stretches out type vent valve mainly by upper cover 11, spring 12, diaphragm 13, lower cover 14, limited block 15,
Bindiny mechanism 16, valve rod 17, and valve 18 are constituted.
During use, malleation is stretched out the lower cover 14 of type vent valve and is connected air, when the air of malleation is passed through valve 18
Time, the pressure in upper cover 11 starts to increase, and when pressure reaches certain value when, spring 12 starts to be compressed,
Valve rod 17 just moves down.When the pressure in upper cover 11 reduces, spring 12 begins to elongation, valve rod 17
Just move up.
And negative pressure indentation type vent valve is the negative pressure that the negative pressure device outside utilization produces, drive vent valve valve rod
Movement, thus control the nozzle ring assembly of variable area turbocharger, regulate turning of turbocharger
Speed.As shown in Figure 2.Negative pressure indentation type vent valve mainly by upper cover 21, spring 22, diaphragm 23, lower cover 24,
Limited block 25, bindiny mechanism 26, valve rod 27, and valve 28 are constituted.
During use, negative pressure indentation type vent valve lower cover 24 connects air, when the air in upper cover 21 is from valve
28 when being pumped, and just produces negative pressure in upper cover 21.At this moment spring starts to be compressed, thus promotes valve rod 27
Move up.When the pressure in upper cover 21 raises, spring 22 starts elongation, and valve rod 27 starts to moving down
Dynamic.
Summary of the invention
The present invention seeks to the defect for prior art exists and a kind of positive compression for turbocharger is provided
Enter type venting regulation valve system.
The present invention for achieving the above object, adopts the following technical scheme that a kind of positive compression for turbocharger
Enter type venting regulation valve system, including being arranged on the upper cover on top and being arranged on the lower cover of bottom；Described lower cover
Side is provided with valve, is provided with main film between described upper cover and lower cover, said primary membrane sheet and described upper cover it
Between be provided with compression spring；The upper end of described compression spring is socketed on the recess that described upper cover is formed down, its
Lower end is connected on the bracket that said primary membrane sheet is formed；
Also including being arranged on the valve rod bottom described lower cover, the upper end of described valve rod extend in described lower cover and wears
Cross that said primary membrane sheet and described compression spring are fixing to be connected；When the pressure in described lower cover increases, described valve rod
Upper shifting under the effect of the pressure；When in described lower cover pressure reduce time, described valve rod under the effect of the pressure under
Move.
Further, auxiliary seal diaphragm it is provided with between described valve rod and described lower cover.
Further, it is provided with limited block between bottom and the said primary membrane sheet of described lower cover.
Further, the valve rod bottom described lower cover is provided with protective cover, and the two ends of described protective cover are passed through
Bindiny mechanism be fixed on described under cover.
Beneficial effects of the present invention: which combines the feature of the vent valve of two kinds of forms of tradition, has structure
Compact simply, reliable operation, use widely advantage.Its compression utilizing turbocharger self to produce is empty
Gas just can realize the indentation of vent valve to control the nozzle ring of variable area turbocharger；Thus it is not required to
Will be by outside negative pressure device.
