Abstract
A valve in a fluid treatment system adapted for controlling the flow of fluid between a source and a treatment media disposed in a treatment chamber. The valve includes a housing having a fluid passageway between an inlet and an outlet; a containment chamber; and a sealing member reciprocal between a first position in which the sealing member is retained in the containment chamber out of the flow of fluid in the passageway and a second position that seals the outlet. The containment chamber also includes a drain opening, which can be a venturi, for emptying the containment chamber of fluid.
Claims21
A valve in a fluid treatment system adapted for controlling the flow of fluid between a source and a treatment media disposed in a treatment chamber comprising:
- a housing having an inlet, an outlet, and a passageway in communication between said inlet and said outlet;
- a sealing member configured to reciprocate in said housing between a first position and a second position, said second position sealing said outlet;
- said housing having containing means configured for retaining said sealing member in said first position out of a flow of fluid in said passageway;
- and
- said containing means including a drain means in fluid communication with said passageway for emptying said containing means of fluid.
A valve in a fluid treatment system adapted for controlling the flow of fluid between a source and a treatment media disposed in a treatment chamber, comprising:
- a housing having an inlet, an outlet, and a passageway in communication between said inlet and said outlet, a portion of said passageway defines a passage chamber;
- a sealing member configured to reciprocate in said housing between a first position and a second position, and said housing having a containment chamber configured for retaining said sealing member in said first position out of a flow of fluid in said passageway and being in fluid communication with said passage chamber so that said sealing member is moveable to said second position for sealing said outlet, wherein said containment chamber includes a drain in fluid communication with said passageway for emptying said containment chamber of fluid.
A valve for use in a fluid treatment system adapted for controlling the flow of fluid between a source and a treatment media disposed in a treatment chamber comprising:
- a housing having an inlet, an outlet and a passageway in communication between said inlet and said outlet;
- a sealing member configured to reciprocate in said housing between a first position out of direct fluid flow in said passageway and a second position in which said sealing member seals said outlet and
- a containment chamber configured for retaining said sealing member in said first position out of the flow of fluid and having a Venturi in a floor of said containment chamber in fluid communication with said passageway.
