Abstract
The present invention provides a kind of metering valve component, including valve (1) and bushing (2), the bushing (2) includes oil inlet (201) type hole (202), the valve (1) is the cylinder for having inner chamber, including metrology window (101), the metrology window (101) and the inner chamber UNICOM of the valve (1), the bushing (2) is mounted in the valve (1) outside by gap engagement sleeves, the oil inlet (201) and the inner chamber UNICOM of the valve (1), the valve (1) metrology window (101) and axially coincident area change of the type hole (202) when axially moving, the valve (1) around axle do circumferential movement when, the metrology window (101) and the circumferential overlapping area of the type hole (202) change.This metering valve component can realize the motion of axial and axial both direction, can meet two control variables while control metered flow.
Description
Technical field
The invention belongs to mechanical field, is mainly used in hydraulic system, more particularly to a kind of metering valve component.
Background technology
In general metering valve component is only capable of experiencing an input variable, and only a kind of motion mode, generally impression are lived
The pressure of two chambers after in front of the door, valve are axially moved, and change the area of metrology window, realize that flow changes and become with input pressure
Change.If flow needs to experience two variables, that is, when having two variables to change flow, traditional metering valve component is just
It can not meet require that.
The content of the invention
The purpose of the present invention is：The structure of this metering valve component can realize the fortune of axial and circumferential both direction simultaneously
It is dynamic, you can to realize two variables simultaneously while control metering valve aperture, so as to meet some complex control needs.
Technical solution of the present invention provides a kind of metering valve component, including valve 1 and bushing 2, and the valve 1 is to have inner chamber
Cylinder, including metrology window 101, the inner chamber UNICOM of the metrology window 101 and the valve 1, the bushing 2 include into
Hydraulic fluid port 201 and type hole 202.The bushing 2 is mounted in outside the valve 1 by gap engagement sleeves, the oil inlet 201 and the work
The inner chamber UNICOM of door 1, the valve 1 metrology window 101 and axially coincident area of the type hole 202 when axially moving
Change, the valve 1 around axle do circumferential movement when, the circumferential overlapping area of the metrology window 101 and the type hole 202 becomes
Change.
Preferably, one end of the valve 1 also includes control chamber 102, valve described in the oil pressure cntrol of the control chamber 102
1 axial movement.
Preferably, the valve 1 also includes the splined shaft 103 of external splines relative to the other end of control chamber 102, described
Splined shaft 103 can be connected with the transmission mechanism with internal spline, applied the power that rotates in a circumferential direction to the valve 1, driven the valve 1
Rotate in a circumferential direction.
It is an advantage of the invention that：This metering valve component can realize the motion of axial and axial both direction, Ke Yiman
Two control variables of foot control metered flow simultaneously.
Brief description of the drawings
Accompanying drawing of the present invention is illustrated below：
Fig. 1 is the structural representation of metering valve in metering valve component provided by the invention；
Fig. 2 is the structural representation of bushing in metering valve component provided by the invention；
Fig. 3 is embodiment when being applied to certain fuel oil regulating device based on metering valve provided by the invention；
The leverage sketch that Fig. 4 is installed when being and being applied based on metering valve provided by the invention.
Embodiment
Fig. 3 is embodiment when metering valve is applied to certain fuel oil regulating device.
The fuel pressure of valve control chamber becomes hour, and the valve 1 axially moves to the one end of control chamber 102, the meter
The axially coincident area for measuring window 101 and the type hole 202 becomes big, and metering fuel flow becomes big.
When the fuel pressure of valve control chamber becomes big, the valve 1 axially moves to the one end of spline 103, the metering
Window 101 and the axially coincident area of the type hole 202 diminish, and metering fuel flow diminishes.
The lever of internal spline is provided with based on valve splined shaft 103 provided by the invention, and is fixed with nut, sees Fig. 3.
Lever one end is equipped with back-moving spring, the other end and ejector pin contact, sees Fig. 4.
When push rod is pushed forward (see Fig. 4), push rod drives lever to rotate counterclockwise, internal spline and valve on lever
Splined shaft 103 on 1 coordinates, and drives valve 1 to rotate counterclockwise, the metrology window 101 is axially coincident with the type hole 202
Area diminishes, and metering fuel flow diminishes.
