Abstract
The utility model relates to a multi-path reversing valve. The multi-path reversing valve comprises a valve body; a valve core is mounted in the middle of the valve body; the valve core is in central symmetry; two annular grooves are formed in the valve core; the valve body is also provided with a working oil port A and a working oil port B; a central hole is machined in the left end face of the valve core, and a screw thread is also machined to be in restoration connection with a spring of the multi-path reversing valve; a radial small hole is machined in the small cylindrical bulge on the right end of the valve core and is connected to a manual control mechanism; an axial small hole is machined in a big cylinder on the right end of the valve core and is used for installation of a locating pin during the non-manual control to prevent the valve core from rotating in the valve body; two radial small holes are machined in the big cylinder on the left end of the valve core and provide returned oil liquid which is loaded with a feedback signal when the valve core is at the middle position.
Description
Technical field
The utility model relates to selector valve, is specifically related to a kind of multiple directional control valve.
Background technique
On engineering machinery, building machinery, petroleum machinery, mine equipment and ship machinery etc., the spool Median Function of the multiple directional control valve of application is more single in the market, and when the work of manipulation multiple directional control valve makes spool be parked in meta, equipment is in action.In practical work process, when a certain way reversing valve spool of multiple directional control valve is parked in meta, the equipment that this way reversing valve is controlled also can require action; Or when multiple directional control valve, wherein a way reversing valve spool is not when meta is worked, and the spool of other way reversing valves, at meta, also requires the equipment that other way reversing valves are controlled to move.Conventional multi-way reversing valve core Median Function cannot meet.
Summary of the invention
For the present situation of above-mentioned prior art, it is a kind of simple in structure that technical problem to be solved in the utility model is to provide, the multiple directional control valve that can solve the problems of the technologies described above.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of multiple directional control valve, comprise valve body, in the middle of this valve body, spool is installed, symmetrical centered by this spool, on this spool, have two circular grooves, on described valve body, be also provided with actuator port A and actuator port B.
Further, described spool left end is provided with big column, has two radial holes in this big column.
Further, described spool left side is provided with center hole, in this center hole, is provided with screw thread.
Further, described spool right-hand member is provided with projection, and this projection has through hole.
Compared with prior art, the utility model has the advantage of: in machining center hole, the left side of spool, and be processed with screw thread, effect is to be connected with the spring reset of multiple directional control valve, in the right-hand member small column projection of spool, be processed with a radial hole, effect is to be connected with manual control mechanism, on the right-hand member big column of spool, be processed with an axial aperture, effect is when non-manual control, locating stud is installed, prevent that spool from rotating in valve body, on the left end big column of spool, be processed with two radial holes, effect is at spool during at meta, be to provide the fluid oil return of load feedback signal.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of multiple directional control valve, comprise valve body, in the middle of this valve body 1, spool 3 is installed, symmetrical centered by spool 3, on spool 3, have two circular grooves, on described valve body, be also provided with actuator port A2 and actuator port B5, spool left end is provided with big column, in this big column, have two radial holes, spool left side is provided with center hole, in this center hole, be provided with screw thread, spool right-hand member is provided with projection, this projection has through hole 4, symmetrical centered by the agent structure of spool, on spool, process two circular grooves, by changing the groove width of circular groove and the sharp edge-shaped at circular groove two ends, realize different spool Median Functions.During spool meta, the sharp edge of the outer end of two circular grooves of spool and the oil return groove of valve body in opened condition, pressure oil sealing, the spool of this structure is mainly used in requiring equipment when not working, the two ends fluid of equipment be communicate and oil return, during spool meta, the sharp edge of the outer end of two circular grooves of spool and the oil return groove of valve body are closed condition, the sharp edge of the outer end of two circular grooves of spool is processed as cone type structure, and in the whole movement travel of spool, the sharp edge of the outer end of two circular grooves of spool and the oil return groove of valve body are all closed condition, the sharp edge of the fluid of actuator port A mouth and B mouth by the outer end of two circular grooves of spool is processed as the oil return groove of cone type structure and valve body and links up, pressure oil sealing, the spool of this structure is mainly used in requiring equipment when not working, it is motionless that equipment is parked in corresponding position, simultaneously at spool not when meta is worked, the fluid oil return of equipment has throttling, produce back pressure, make equipment work more steady.The conical surface angle of the sharp edge of the outer end by change spool two circular grooves, realizes the demand of working attachment different flow, and angle is larger, and flow is larger, when angle is that 90 degree make, is the peak rate of flow of multiple directional control valve.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technological scheme that still can record aforementioned each embodiment modifies, or part technical characteristics is wherein replaced on an equal basis; And these modifications or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
