The form of the described valve body can be cylindrical shell body with ring end surface, and on the cylindrical shell body of the described valve body at least two oil holes are set, on end surface of the described valve body is equipped with end cover, and its another end surface is equipped with press plate, on the described press plate a panel is set, and the outer side of the described end cover is equipped with joint, and the described washer is set between the described joint and the described end cover, and the described valve core is placed in the cylindrical shell body of the described valve body.
Description
Technical field:
The present invention relates to a kind of pilot operated directional control valve, particularly a kind of pilot operated directional control valve that is used for mechanical operating table.
Background technique:
In existing technology, tilting of mechanical operating table all controlled with cylinder control or with gear transmission, and there is following shortcoming in these two kinds of structures: 1, running precision is poor; 2, processing difficulties; 3, cost height.
Summary of the invention:
Technical problem to be solved by this invention is: there is following shortcoming in the existing mechanical operating table: 1, running precision is poor; 2, processing difficulties; 3, cost height.
The present invention solves the problems of the technologies described above the technological scheme that is adopted to provide a kind of operating table pilot operated directional control valve, described a kind of operating table pilot operated directional control valve is by handle, spool, panel, pressing plate, valve body, end cap, packing ring and joint constitute, the shape of described valve body can be for having the round casing housing of annular end face, the round casing housing of described valve body is provided with at least two oilholes, one end of described valve body is provided with end cap, the place, other end is provided with pressing plate, can be connected by screw between described end cap and the described valve body, described pressing plate is provided with panel, can be connected by screw between described panel and the described pressing plate, the arranged outside of described end cap has joint, between described joint and described end cap, be provided with described packing ring, described spool is arranged in the round casing housing of described valve body, the shape of described spool can be cylindrical body, described spool is provided with oilhole, the center line of described spool and the center line of described valve body overlap, one end of described spool passes described pressing plate and panel, the inboard of the other end and described end cap is in contact with one another, external part at described spool is provided with handle, can be between described handle and the described spool for being threaded, described handle is vertical mutually with described spool.
The present invention and prior art contrast, because used pilot operated directional control valve, can realize with the tilting and rise of oil hydraulic pump control operating table, and the running precision height of operating table, easy to process and cost is low.
