Description
Technical field
The utility model belongs to plane hydraulic system technical field, more particularly to a kind of flow control valve assembly.
Background technology
Existing flow control valve assembly structure is most of more complicated, is made up of multiple components, such as flow coarse adjustment portion
Subassembly, flow accurate adjustment members, spare part are more, and volume is larger.
Utility model content
The purpose of this utility model：A kind of flow control valve assembly is provided, existing flow is controlled to the stream of valve assembly
Amount coarse adjustment members and flow accurate adjustment members merge into a component, reduce number of parts, and further realizing makes stream
The constant function of amount.
The technical solution of the utility model：
A kind of flow controls valve assembly, including nut, sealing ring, valve, spring, overcoat, pad, bushing, sealing ring,
Back-up ring, wherein, pad, spring, valve, sealing ring, sealing ring are loaded in bushing successively, and nut is fixed on bushing left end, overcoat
It is enclosed on bushing, back-up ring is fixed on bushing, nut has endoporus A, a hole d is arranged at valve bottom, and there are hole e, bushing in valve side
Lateral aperture has hole f.
Further, nut is hexagonal socket nut.
The hole of valve side has 1 or 2, and accordingly the hole of bushing lateral aperture has 1 or 2.
Advantage of the present utility model：
Flow control valve assembly realizes that the major part of constant current is made up of valve, spring, overcoat, pad, spring, works
After liquid is flowed into from A holes, by positioned at the less d holes coarse adjustment constant flow of valve bottom part aperture diameter；And adjusted by the quantity for increasing and decreasing pad
Whole pre-pressure of the spring, makes spring force and the fluid pressure balance of import, it is ensured that the e holes of valve side are relative with bushing lateral aperture f's
Position, controls the size of flow area, so as to realize the accurate adjustment to flow.Flow control valve assembly is simple in construction, and part is few,
Reliability is high.

Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
A kind of flow controls valve assembly, including nut, sealing ring, valve, spring, overcoat, pad, bushing, sealing ring,
Back-up ring, wherein, pad, spring, valve, sealing ring, sealing ring are loaded in bushing successively, and nut is fixed on bushing left end, overcoat
It is enclosed on bushing, back-up ring is fixed on bushing, nut has endoporus A, a hole d is arranged at valve bottom, and there are hole e, bushing in valve side
Lateral aperture has hole f.
Further, nut is hexagonal socket nut.
The hole of valve side has 1 or 2, and accordingly the hole of bushing lateral aperture has 1 or 2.
Working solution is flowed into from A holes, during through d holes, because the aperture in d holes is smaller with respect to A holes, therefore can adjust stream roughly
Measure Q.
F=f Δs P12, wherein：ΔP12=P2-P1, Δ P12Act on the effective area f of valve, F is balanced with T-phase.
Change T size by increasing and decreasing adjust pad, so as to adjust the relative position of valve and bushing.
When flow Q changes, suitably adjust the rigidity of spring to adjust the aperture in e holes, flow is finely adjusted, makes it
Keep constant.
ΔP23=P2-P3If, P3Increase then Δ P23Reduce, flow Q is reduced, so as to cause Δ P12Reduce, then F is less than T,
Valve is moved to the left, and adjustment hole is opened greatly, flow increase, returns to original flow.
Pre-pressure of the spring can be adjusted by increasing and decreasing the quantity of pad, make spring force and the fluid pressure balance of import, it is ensured that
The e holes of valve side and bushing lateral aperture f relative position, control the size of flow area, so as to realize the accurate adjustment to flow.
Flow control valve assembly is simple in construction, and part is few, and reliability is high.
