Plunger valve by valve body, valve cover, stem, plunger, sealing ring, hand wheel and sporadic form attachments. When rotating the handwheel, through the valve rod drives the plunger, the plunger reciprocating inclined cone and seat cone clutch, complete opening and closing of the valve.
In the valve, USES the interference fit between plunger and seal. Pressure across the valve cover retaining bolt tight, make the seal ring is compressed, inner ring present tight circle against the valve cavity wall, beyond the Great Wall so on sealing ring radial component force would be generated by the pressure of the fluid, thus ensuring the sealing, to eliminate the external leakage.
The adoption of resilience is strong, sealing ring and bonding high nontoxic new sealing material, so the sealing is reliable, durable. The seat and taper sealing plunger parts ?
