초록 ▼

A button-operated main shut-off and flow-control valve is disclosed which attaches directly to a supply cylinder in place of the conventional rotary-stem shut-off valve. Magnetic actuators in the valve eliminate the hazards of leaky seals around moving or rotating parts. Excess flow control is provided by internal valve elements which inhibit further fluid flow in excess of a design limit, and pressure regulation is provided within the same housing so that extremely low profile is preserved and fluid connections are significantly reduced for improved operating safety.

대표청구항 ▼

An apparatus for controlling fluid flow comprising: a housing having a chamber operatively communicating with an inlet and outlet; a first valve seat in said chamber interposed between said inlet and outlet; a first element received in said housing movable between open and closed position with said first valve seat; means for biasing said first element to one of said open and closed positions; control means freely received in said housing for movement toward and away from selective engagement with a surface adjacent said first valve seat, said control means having a magnet facilitating generally axial movement of said control means in said housing; a first actuator disposed between said first element and control means, said first actuator imparting movement to said first element through a first range of movement of said first element when said first actuator abuttingly engages both said first element and said control means, and said first element being unaffected by said first actuator through a second range of movement of said first element; a shield means extending outwardly from a first face of said control means toward said first valve seat for impeding development of Bernoulli forces between said control means and said surface adjacent said first valve seat, said shield means including plural, spaced apart openings extending generally laterally through said shield to permit fluid flow therethrough when said control means operatively engages said surface adjacent said first valve seat and reducing oscillatory motion of said control means; and, an actuating magnet externally mounted to said housing and magnetically interactive with said control means magnet, said actuating magnet being selectively positionable relative thereto whereby said control means is selectively axially shifted.
