Abstract
The inventive valve makes the oil from an oil pump to change liquid flow direction by a reserving fixed disk, an operation board and six reserving ports and it can control a plurality of executive body of a hydraulic system. The six reserving ports make the valve to be a rectangular reserving bore so as to reduce the stroke of the operating level.
Description
Technical field:
The present invention relates to a kind of novel (rotation square position) rotary valve multiple directional control valve, multiple directional control valve is a kind of combination brake switch and proporting of centralized selector valve, be mainly used in hydraulic shovel, on loader lifting transport airplane and other engineering machinery, to the centralized control of a plurality of actuators (oil cylinder or oil motor).
Background technique:
In the known technology the existing multiple directional control valve of color usefulness, the rotatable and spool gliding style multiple directional control valve structure technology for spool.Survey inspection according to my actual maintenance in the past few years.Find that therefrom existing spool is rotatable to have following deficiency with spool gliding style multiple directional control valve structure technology.Now get rid of with repairing complete works of with practical hydraulic machinery fault, Hunan science tech publishing house, in May, 2002 front page the 5th printing (the 218th page), (the 219th page), (the 222nd page) and modern project mechanical-hydraulic and hydraulic systems, basic principle, trouble analysis and eliminating, in People's Transportation Press's March in 2003 the 1st edition the 2nd printing (the 45th page) books, the rotatable and spool gliding style multiple directional control valve structure technology of described spool is an example:
The hydraulic coupling force bearing point was a sliding friction when 1, existing valve was worked, and caused operating force to strengthen, and had accelerated the inclined to one side scouring of spool and valve body slip surface and had decreased.
2, inconvenience was repaired and is changed after existing valve core and valve body slip surface wearing clearance increased, and promptly was that place under repair is changed, and also can cause certain economic loss to the user.Whole valve is disposable scraps so cause.
3, existing valve uses middle and later periods spool and the empty slip surface wearing and tearing of body cavity, so that after spool and the gap increase of body cavity sky slip surface, can't adjust, and makes that this valve middle and later periods service behaviour is bad and scraps in advance.
As long as properly settling with the experimental fact proof after testing makes the adjustment of slip surface matching gap reduce.Be convenient to change with wearout parts, just can improve the value of several times on this valve.As long as the invention of hydraulic coupling force bearing point is rolling friction during this valve work.Just can make that operation is light, reduce wear.
Summary of the invention:
The objective of the invention is:, invent a kind of (rotation square position) rotary valve multiple directional control valve at existing shortcoming and defect part in the above-mentioned prior art.Characteristics such as it has simple in structure, and cost is low, and the middle and later periods workability is reliable, and it is little to operate light wearing and tearing, and utility time is long.
Technological scheme of the present invention is in order to achieve the above object:
1, will have (rotational valve core) rotary valve and (sliding valve core) sliding valve style multiple directional control valve now, invention is (rotation square position) rotary valve multiple directional control valve, just pass through, the present invention commutate fixed tray (32), switch operation dish (35), plane bearing (37), planar axes bearing (30), constitute multiple directional control valve of the present invention, hydraulic coupling force bearing point rolling friction during work, make that operation is light, reduce wear that it is convenient that commutation fixed tray (32), switch operation dish (35), repairing are changed.
2, the present invention passes through: after adjusting swash plate (40), adjustment bolt (14), adjustment nut (27), adjustment bolt positioning cards (22), the wearing and tearing of formation commutation board slip plane, matching gap increase in plane can rationally be adjusted.
3, the present invention: by, cylinder commutation mouthful (56) that the neutral oil extraction of commutation fixed tray commutates mouthful (50), commutation fixed tray oil deoils, the next oil commutation of operating panel oil pump mouthful (25), the oil return of operating panel oil cylinder are changed mouthful (60), operating panel neutrality oil extraction commutation mouthful (51), are constituted rectangle commutation bore, to reduce the operating stem stroke, make operation more convenient.
The invention has the beneficial effects as follows:
It has simple in structure, and cost is low, reliable working performance.Matching gap can be adjusted between commutation chassis and switch operation dish two slip surfaces.Commutation chassis and switch operation dish two slip surfaces are convenient to repair if any accidental injury and are changed.The operating stem stroke is short, with characteristics such as time length.
