Abstract
The utility model discloses an improved 4WMM16-5X hand-operated direction valve which comprises a valve body (1). The improved 4WMM16-5X hand-operated direction valve is characterized in that a casting technique hole is not formed in the valve body (1), and X, Y port cores are eliminated in valve body casting. According to the improved 4WMM16-5X hand-operated direction valve, the structure is simple, the X, Y port cores are eliminated in the valve body casting, casting cost is low, the procedures of bearizing, countersinking and tapping for the casting technique hole are eliminated, manual cost is reduced, generation of oil leakage phenomena of the casting technique hole is avoided, service life of the valve is prolonged, and maintenance expenses are saved.
Description
Technical field
The utility model relates to hydrovalve, belongs to hydraulic machinery and makes the field, is specifically related to a kind of modified model 4WMM16-5X hand-operated direction valve.
Background technique
The end face of the valve body of conventional 4WMM16-5X hand-operated direction valve has two casting technique holes, end face oil impregnate phenomenon in use must be appearred in two casting technique hole reamings, counterbore, tapping sometimes man-hour adding,
Summary of the invention
The purpose of this utility model is: a kind of modified model 4WMM16-5X hand-operated direction valve is provided, reduces production costs and cast difficulty of processing, avoid the generation of oil impregnate phenomenon.
Technical solution of the present utility model is: this hand-operated direction valve comprises valve body, it is characterized in that: without the casting technique hole, save X, Y mouth loam core during the valve body casting on the valve body.
The utility model has the advantages that: simple in structure, save X, Y mouth loam core during the valve body casting, save the casting cost, save reaming, counterbore, tapping procedures to the casting technique hole, reduce cost of labor, avoid the generation of casting technique hole oil impregnate phenomenon, prolong the working life of valve, save maintenance expenses.
