Abstract
The invention provides a metering valve assembly. The metering valve assembly comprises a valve (1) and a bush (2). The bush (2) comprises an oil inlet (201) and a shaped hole (202). The valve (1) is a cylinder provided with an inner cavity and comprises a metering window (101). The metering window (101) communicates with the inner cavity of the valve (1). The valve (1) is sleeved with the bush (2) in a clearance fit mode. The oil inlet (201) communicates with the inner cavity of the valve (1). The axial overlapping area of the metering window (101) and the shaped hole (202) changes when the valve (1) moves in the axial direction, and the circumferential overlapping area of the metering window (101) and the shaped hole (202) changes when the valve (1) moves around the axis in the circumferential direction. According to the metering valve assembly, movement in the axial direction and movement in the circumferential direction can be achieved, and the requirement for controlling and metering the flow according to two control variables can be met.
Description
Technical field
The invention belongs to mechanical field, be mainly used in hydraulic system, particularly to a kind of metering valve assembly.
Background technology
General metering valve assembly is only capable of one input variable of impression, only has a kind of motion mode, is generally and experiences the pressure in two chambeies before and after valve, and valve axially-movable changes the area of metrology window, it is achieved flow changes with input pressure change.If flow needs two variablees of impression, when namely having two variablees all can change flow, traditional metering valve assembly just cannot meet and require that.
Summary of the invention
It is an object of the invention to: the structure of this metering valve assembly can realize the motion of axial and circumferential both direction simultaneously, namely can realize two variablees simultaneously and control metering valve aperture simultaneously, such that it is able to meet some complex control needs.
Technical solution of the present invention provides a kind of metering valve assembly, including valve 1 and lining 2, described valve 1 is the cylinder having inner chamber, including metrology window 101, the inner chamber UNICOM of described metrology window 101 and described valve 1, described lining 2 includes oil-in 201 and type hole 202.Described lining 2 is sleeved on outside described valve 1 by matched in clearance, the inner chamber UNICOM of described oil-in 201 and described valve 1, described valve 1 is the axially coincident area change in described metrology window 101 and described type hole 202 when axially moving, described valve 1 is when axle does circumferential movement, and the circumferential overlapping area in described metrology window 101 and described type hole 202 changes.
Preferably, one end of described valve 1 also includes controlling chamber 102, the axially-movable of valve 1 described in the oil pressure cntrol in described control chamber 102.
Preferably, described valve 1 also includes the splined shaft 103 of external splines relative to the other end controlling chamber 102, and described splined shaft 103 can be connected with the drive mechanism with internal spline, rotates in a circumferential direction power to the applying of described valve 1, drives described valve 1 to rotate in a circumferential direction.
The invention have the advantage that this metering valve assembly can realize the motion of axial and axial both direction, it is possible to meet two control variable and control metered flow simultaneously.
Accompanying drawing explanation
Below accompanying drawing of the present invention is illustrated:
Fig. 1 is the structural representation of metering valve in metering valve assembly provided by the invention；
Fig. 2 is the structural representation of lining in metering valve assembly provided by the invention；
Fig. 3 is based on embodiment when metering valve provided by the invention is applied to certain fuel oil regulating device；
The leverage sketch that Fig. 4 installs when being based on metering valve provided by the invention application.
Detailed description of the invention
Fig. 3 is metering valve embodiment when being applied to certain fuel oil regulating device.
When the fuel pressure in valve control chamber diminishes, described valve 1 axially moves to controlling one end, chamber 102, and described metrology window 101 becomes big with the axially coincident area in described type hole 202, measures fuel flow and becomes big.
When the fuel pressure in valve control chamber becomes big, described valve 1 axially moves to spline 103 one end, and the axially coincident area in described metrology window 101 and described type hole 202 diminishes, and metering fuel flow diminishes.
It is provided with the lever of internal spline based on valve splined shaft 103 provided by the invention, and fixes with nut, see Fig. 3.Fig. 4, equipped with back-moving spring, the other end and ejector pin contact, is seen in lever one end.
When push rod is pushed forward (see Fig. 4), push rod drives lever to rotate counterclockwise, internal spline on lever coordinates with the splined shaft 103 on valve 1, valve 1 is driven to rotate counterclockwise, the axially coincident area in described metrology window 101 and described type hole 202 diminishes, and metering fuel flow diminishes.
