An anti-rotation structure for a hydraulic spool valve core, comprising a spool valve core, a valve body end cover and an anti-rotation spool, characterized in that there is an anti-rotation spool mounting hole at the shaft end of the spool, and the The end cover of the valve body is provided with an anti-rotation spool sliding groove extending parallel to the axis of the valve core. One end of the anti-rotation spool is arranged in the anti-rotation spool installation hole, and the spool installation hole and the spool are gaps. The shaft hole is matched, and the other end of the anti-rotation spool is arranged in the sliding groove of the anti-rotation spool; the valve core drives the anti-rotation spool to slide in the anti-rotation spool sliding groove of the valve body end cover during the axial movement process. The anti-rotation structure of the spool of the hydraulic slide valve is simple in structure, easy to process and assemble, does not require high precision, and does not affect the control performance of the valve.
Description
Technical field
The present invention relates to the anti-rotation mechanism of a kind of hydraulic efficiency slide valve spool, particularly for the anti-circumferential rotation structure of pilot proportional directional control valve valve core of main valve.
Background technique
Because Proportional valve has, contamination resistance is strong, control performance can meet the advantages such as most industrial process needs, so Proportional valve has application extremely widely in the fluid control field.The control valve port of Proportional valve adopts non-all-round valve port form to have the valve port characteristic of the better linearity with acquisition, and adopt non-all-round valve port, may there be asymmetry in fluid to the circumferential active force of spool, thereby make subsidiary the generation circumferentially in the axially movable process of spool rotate, the wearing and tearing of aggravation spool and valve body.
In existing hydraulic efficiency slide valve product, the common anti-rotation structure of spool is thread mill drilling on end cap, and anti-rotation screw is installed, and processes spacing sliding-groove on spool, by screw, spool is circumferentially carried out to the spacing spool revolution that prevents.This structure processing is more complicated, the inconvenience assembling, and be processed with tapped through hole on end cap, and need be sealed, higher to the requirement on machining accuracy of sealing surface.
Summary of the invention
For solving prior art complex structure, inconvenience assembling and the high problem of requirement on machining accuracy, the invention provides the anti-rotation structure of a kind of spool of the hydraulic efficiency slide valve with anti-rotation traveller.
For achieving the above object, the present invention has adopted following technological means: a kind of anti-rotation structure of hydraulic efficiency slide valve spool, comprise valve core of the spool valve, valve body end cap and anti-rotation traveller, it is characterized in that: described spool axial end has an anti-rotation traveller mounting hole, described valve body end cap is provided with the anti-rotation traveller sliding-groove extended along being parallel to valve core axis's direction, one end of anti-rotation traveller is arranged in anti-rotation traveller mounting hole, described traveller mounting hole and traveller are the gap shaft hole matching, and the other end of anti-rotation traveller is arranged in anti-rotation traveller sliding-groove; Spool drives anti-rotation traveller and slides in the anti-rotation traveller sliding-groove of valve body end cap in moving axially process.
The contact jaw of described traveller and sliding-groove be shaped as arc surface.
Traveller mounting hole of the present invention is the gap shaft hole matching with coordinating of traveller, and traveller can move up and down in the traveller mounting hole, can reduce the slip surface requirement on machining accuracy of sliding-groove; The contact jaw of traveller and sliding-groove is processed as arc surface, reduces the frictional force in sliding process, and the motion reduced valve core of the spool valve applies extra resistance.
Advantage of the present invention is: simple in structure, be convenient to processing, assembling, and do not increase extra highi degree of accuracy between different parts and coordinate requirement, do not increase extra seal request in valve body; Between anti-rotation traveller and sliding-groove, frictional force is little, and the spool of hydrovalve is not produced to large additional external force, does not affect the control performance of valve.

Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
As shown in Figure 2 and Figure 3, a kind of anti-rotation structure of hydraulic efficiency slide valve spool, comprise valve core of the spool valve 2, valve body end cap 6 and anti-rotation traveller 4, it is characterized in that: described spool axial end has an anti-rotation traveller mounting hole 3, described valve body end cap 6 is provided with the anti-rotation traveller sliding-groove 5 extended along being parallel to valve core axis's direction, one end of anti-rotation traveller 4 is arranged in anti-rotation traveller mounting hole 3, described traveller mounting hole 3 is the gap shaft hole matching with traveller 4, and the other end of anti-rotation traveller 4 is arranged in anti-rotation traveller sliding-groove 5; Spool 2 drives anti-rotation traveller 4 and slides in the anti-rotation traveller sliding-groove 5 of valve body end cap 6 in moving axially process.
The contact jaw of described traveller 4 and sliding-groove 5 be shaped as arc surface.
Finally it should be noted that, the foregoing is only preferred embodiment of the present invention, rather than, to the restriction of technical solution of the present invention, any being equal to that the technology of the present invention feature is done, replace and corresponding improvement, still within protection scope of the present invention.
