Apparatuses to enable single-point valve control of siphons, siphon pumps, metering siphon pumps, and turbine siphon pumps include terminal anti-backflow valves, a system flow control valve, a metering chamber, a self-regulating chamber, and a siphon turbine. The terminal anti-backflow valves provide automatically closable systems without further priming after an initial prime. The system flow control valve consolidates functions for priming, pumping, dispensing, and siphon flow regulation to provide single-point valve control. The metering chamber operated by a single-point system flow control valve enables periodic dispensing of liquid above a supply source. The self-regulating chamber controls a single-point system flow control valve to regulate a metering chamber for periodic dispensing. The siphon turbine provided with terminal anti-backflow valves and regulated by a single-point system flow control valve enables hydropower production. Benefits include precision control, single-point operation, safety, new applications, energy savings, installations without power facilities, and a renewable clean energy technology. |

1. A closable siphon pump system with single-point valve control featuring an improved system flow control valve apparatus to prime, pump, and regulate siphon flow, and terminal anti-backflow valves to maintain system prime to transfer liquids from a supply source via siphoning over an elevation in an uninterrupted stream to a point below said supply source above or within a destination; to forcibly pump liquids from said supply source to said point above or below said supply source and above or within said destination; and to forcibly prime said closable siphon pump system to establish system siphon flow without further priming after an initial prime, said closable siphon pump system comprising: a) a prior art siphon pump system comprising: (1) a first siphon conduit extending upward from an inlet of said first siphon conduit submerged within a liquid supply source to an outlet of said first siphon conduit communicating with an inlet of said improved system flow control valve apparatus disposed above said liquid supply source for upward movement of system siphon flow; (2) a second siphon conduit extending downward from an outlet of said improved system flow control valve apparatus disposed above said liquid supply source and communicating with an inlet of said second siphon conduit for downward movement of system siphon flow to an outlet of said second siphon conduit disposed below said liquid supply source and within or above said destination, and said second siphon conduit of greater length than said first siphon conduit sufficient to establish system siphon flow by force of gravity; (3) an anti-backflow valve communicating with said outlet of said second siphon conduit to establish one-way directional system siphon flow from said inlet of said first siphon conduit upward through said improved system flow control valve apparatus and downward through said second siphon conduit to exit said outlet of said second siphon conduit disposed below said liquid supply source within or above said destination; to prevent reverse flow into said second siphon conduit; and to provide an automatically closable second siphon conduit upon closure of said improved system flow control valve apparatus to retain prime for system readiness without further priming after said initial prime; b) wherein the improvement comprises: (4) an anti-backflow valve communicating with said inlet of said first siphon conduit to establish one-way directional system siphon flow from said inlet of said first siphon conduit upward through said improved system flow control valve apparatus and downward through said second siphon conduit to exit said outlet of said second siphon conduit disposed below said liquid supply source within or above said destination; to prevent return of liquid to said liquid supply source; and to provide an automatically closable first siphon conduit upon closure of said improved system flow control valve apparatus to retain prime for system readiness without further priming after said initial prime; and (5) the improved system flow control valve apparatus for single-point valve control communicating with said outlet of said first siphon conduit and said inlet of said second siphon conduit disposed above said liquid supply source to control start, stop, restart and vary system siphon flow through said first siphon conduit, said improved system flow control valve apparatus, and said second siphon conduit; to provide immediate control to transfer liquids from said liquid supply source via siphoning over said elevation in a selectively variable stream to exit below the supply source at said point above or within said destination; to control retention of system prime by means of said terminal anti-backflow valves responding automatically to closure of said improved system flow control valve apparatus without further priming after said initial prime; to forcibly prime said first siphon conduit, said improved system flow control valve apparatus, and said second siphon conduit to establish system siphon flow; and forcibly pump liquid above or below said liquid supply source to said point above or within said destination; said improved system flow control valve apparatus comprising: (a) a three-way valve body consisting of an upper valve body conduit and a side valve body conduit forming a valve controllable siphon flow path to enter said side valve body conduit from said outlet of said first siphon conduit and exit an outlet of a lower valve body conduit communicating with said inlet of said second siphon conduit; said upper valve body conduit and said lower valve body conduit forming an inline path for a valve stem assembly; and said upper valve body conduit externally threaded at an upper extremity to mate a removable cap, and disposed to accept said valve stem assembly; (b) said removable cap internally threaded to mate with said externally threaded upper extremity of said upper valve body conduit; an internally threaded central aperture to engage said valve stem assembly to control priming, pumping, and siphon flow; and said internally threaded central aperture encircled by perforations for air exchange during priming; and (c) said valve stem assembly comprising a shaft consisting of an upper threaded portion and a lower unthreaded portion, wherein said lower unthreaded portion is of a smaller diameter than said upper threaded portion; an upper air control valve seal and a lower siphon control valve seal affixed to said lower unthreaded portion; said upper threaded portion to engage a handle or other means of actuation at an upper extremity, and to engage an internally threaded central aperture of an internally threaded removable cap to control system siphon flow by rotating said valve stem assembly to position said upper air control valve seal within said upper valve body conduit to prevent entry of air into said siphon flow path, and position said lower siphon control valve seal in said siphon flow path to start, vary, stop, and restart siphon flow through said siphon flow path; and said upper threaded portion disengaged from said internally threaded removable cap by upward rotation until said lower unthreaded portion of said shaft passes freely through said internally threaded central aperture of said internally threaded removable cap to guide said valve stem assembly linearly to prime said closable siphon pump system by reciprocating said valve stem assembly to establish system siphon flow. |
