The described seal ring I 3 that is enclosed within valve pocket 5 tops contacts with the bottom surface extruding of control cover plate 2.
Described seal ring II 4 all contacts with the extruding of integrated bulk 10 inwalls with seal ring IV 9.
Described spool 8 adopts the cone valve type structure, and adds seal ring at the face of being slidingly matched with valve pocket, effectively reduces air pocket and produces, and stops a leak simultaneously.The combination seal form is adopted in axial seal, and sealing material is selected engineering plastics, because of advantages such as it have that good water dissolubility, swelling sclerosis are little, wear resistance and crushing resistance are good.
The two-way plug-in valve spool adopts the cone valve type structure more, and when spool was closed, the valve port between spool and the valve seat was linear sealing, and sealing is reliable, has avoided the leakage between A chamber and the B chamber.
Since the special physicochemical property of aqueous medium, steel and iron parts or Al-alloy parts that water hydraulic two-way plug-in valve control cover plate and integrated bulk adopt surface ceramic deposition to process, and manufacture cost is lower than original stainless steel; Because water hydraulic two-way plug-in valve valve core movement speed, its acceleration that produces is also larger, so spool adopts SiC or Si
3N
4Engineering ceramics.Use SiC or Si
3N
4Engineering ceramics can reduce valve core movement inertia, improves spool frequency of okperation and speed of response, in addition SiC or Si
