Example
Fluoric Rubber Ring for retention O-ring
■ Components A/B ■ Characteristics • Has a side hole φ C to form flow channel. The incoming fluid is pressed at this joint and flow volume at the inlet and outlet varies. • B y rotating Part A to misalign side hole φ C position, the fluid flow becomes more fluent.
■ Components A 1 /B 1 ■ Characteristics • Fluid flow variation at the inlet and outlet becomes relatively narrower due to different structure from conventional type. • Available to secure constant flow rate at any position by rotating Part A 1 .
Casing
E L–shaped Swivel joint is a product for the turn at the time of mold attachment. Note that intermittent or continuous turning of the swivel joint could damage the O–ring, which results in water leakage.
