Abstract
The invention discloses an improved type 4WMM16-5X hand-operated directional valve. The improved type 4WMM16-5X hand-operated directional valve comprises a valve body (1) and is characterized in that no casting auxiliary hole is formed in the valve body (1), and X and Y port loam cores are omitted when the valve body is cast. The improved type 4WMM16-5X hand-operated directional valve is simple in structure, low in casting cost due to the fact that the X and Y port loam cores are omitted when the valve body is cast, chambering, a countersinking and a tapping processes of casting auxiliary holes are omitted, labor cost is lowered, the phenomenon that oil leaks from the casting auxiliary holes is avoided, the service life of the valve is prolonged, and maintenance cost is saved.
Description
Technical field
The present invention relates to hydrovalve, belong to hydraulic machinery and manufacture field, be 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 reaming à counterbore à tapping sometimes man-hour adding,
Summary of the invention
The object of the invention 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 invention is: this hand-operated direction valve comprises valve body, it is characterized in that: on valve body, without casting technique hole, save X, Y mouth loam core during valve body casting.
Advantage of the present invention is: simple in structure, during valve body casting, save X, Y mouth loam core, and save casting cost, save the reaming à counterbore à tapping procedures to casting technique hole, reduce cost of labor, avoid the generation of casting technique hole oil impregnate phenomenon, extend the working life of valve, save maintenance expenses.
Accompanying drawing explanation
Fig. 1 is valve body schematic diagram of the present invention.
In figure: 1 valve body.
Embodiment
As shown in Figure 1, this hand-operated direction valve comprises valve body 1, it is characterized in that: on valve body 1, without casting technique hole, save X, Y mouth loam core during valve body casting.
Claims (1)
