Abstract
The utility model discloses a kind of valve plates of sliding-vane motor, including valve plate ontology, pressure oil window, oil sucking window, with low pressure oil window, valve plate uses and the integrated design of pressure reducing valve, valve opening is equipped in main body, spool and compressed spring are equipped in hole, low pressure oil is provided to the root of blade oil pocket of seal area through this structure, it can achieve the effect that root of blade is close to stator inner surface in the case where being not required to external pressure reducing valve, reduce the leakage of oil liquid in sliding-vane motor, solve the problems, such as that there are local pressure losses in sliding-vane motor external connection pressure reducing valve, the efficiency of raising system.
Description
Technical field
The utility model relates to hydraulic motor field more particularly to a kind of valve plates of huge discharge Ultra-Low Speed sliding-vane motor.
Background technique
Valve plate is main in sliding-vane motor, and there are two functions, first is that and stator, the volume of rotor and blade formation sealing,
Second is that carrying out flow, i.e., in time it is connected to working chamber with inlet port or press oil port according to the volume situation of change of working chamber.
In order to which the blade of the continuous rotary electrohydraulic servo motor when Ultra-Low Speed is run is contacted with stator inner surface always, fixed
Sub- negotiating curved sections, root of blade oil pocket oil liquid is connected to by oil distribution mechanism with top, in the long short radius of workspace i.e. four
Circular arc, root of blade are passed through pressure oil by pressure reducing valve, so that blade is close to stator inner surface when going to this position, only
After contact appropriate, sealing just can guarantee.
But pressure reducing valve is accessed outside the Continuous rotary electrohydraulic servomotor of ultraprecise and will increase the local pressure loss of oil liquid, drop
The efficiency of low system makes it there is a problem of low-speed performance difference.
Utility model content
The utility model provides a kind of new structural valve plate, solves and deposits in sliding-vane motor external connection pressure reducing valve
The local pressure loss the problem of.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
The valve plate of sliding-vane motor, including valve plate ontology, pressure oil window, oil sucking window have hole, hole in valve plate ontology
It is interior to be equipped with spool, spring.
Valve deck is housed on valve plate ontology, is equipped on valve deck and adjusts screw.
Equipped with the technique plug that size is different on valve plate ontology, technique plug will form interference with corresponding fabrication hole and match
It closes.
It is connected in the left side in the hole with oil inlet, right side is connected to low pressure hydraulic fluid port.
The low pressure hydraulic fluid port is interconnected, and is connected to hole.
The beneficial effects of the utility model are: valve plate use with the integrated design of pressure reducing valve, specifically with valve plate
As the valve body of pressure reducing valve, low pressure oil is provided to the root of blade oil pocket of seal area through this structure, root of blade can be made tight
Stator inner surface is pasted, the leakage of oil liquid in sliding-vane motor is reduced, meanwhile, it solves and is deposited in sliding-vane motor external connection pressure reducing valve
The local pressure loss the problem of, the efficiency of system is improved.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of sliding-vane motor valve plate cross-sectional view.
Fig. 2 is the A-A cross-sectional view of valve plate.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to figs. 1 to Fig. 2, the valve plate of sliding-vane motor, including valve plate ontology 6, oil sucking window 10, pressure oil window 11,
There is hole 3 in valve plate ontology, is equipped with spool 1, spring 2 in hole；Valve deck 5 is housed on valve plate ontology, is equipped on valve deck and adjusts spiral shell
Nail 4 exports oil liquid through damping hole and enters 1 bottom of spool, balance each other with spring force for the size of adjustment spring power；It is described
The left side in hole 3 is connected to oil inlet 7, and right side is connected to low pressure hydraulic fluid port 9, for processing damping hole and low pressure oil hole, needs to process
Corresponding fabrication hole is equipped with seal plug 8 for the leakage for preventing oil liquid at corresponding fabrication hole.
Valve body of the valve plate ontology 6 as pressure reducing valve processes the valve opening of pressure reducing valve at the outerplanar position of valve plate,
Together with spool 1, the equal parts of spring 2 form a pressure reducing valve in valve plate together, as shown in Figure 1, oil sources from pressure reducing valve into
Hydraulic fluid port 7 enters spool, and by the decompression of pressure reducing valve, oil liquid is flowed out from low pressure oil hole 9, to act on root of blade, reaches tight
Paste the effect of stator inner surface.
Such as Fig. 1, valve plate has structure involved in enough Space processing the utility model, meanwhile, by valve plate
Outer end face is designed to the shape of end cap, and valve plate is allow directly to be connected with bearing (ball) cover, to simplify to a certain extent
The structure of sliding-vane motor.
Such as Fig. 2, four low pressure oil holes 9 are interconnected, and so that blade is close to stator inner surface when going to this position, guarantee
The low-speed performance of Continuous rotary electrohydraulic servomotor.
