## Title
Remote operable corporation stop for water supply sources

## Abstract

A system connectable to a water line for controlling the flow of water includes an underground housing, a shut-off mechanism disposed within the housing and connected to the water lines, and a controlling mechanism including a wand for sending a signal to the shut-off mechanism and thereby open and close the system. The shut-off mechanism includes a motor, an actuator interface, and a drive shaft operably connected to each other wherein the drive shaft rotates based upon the signal from the wand so that water flow can be adjusted as desired by an operator. The controlling mechanism includes an antenna and transceiver for communicating with the wand. The actuator interface is coupled to the antenna for processing and communicating a signal received from the wand and transmitting same to the motor and drive shaft.

BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to a corporation stop for water supply sources and, more particularly, to a corporation stop that may be remotely operated by a user.
2. Prior Art
A shutoff valve is adapted to control the water flow between a water source and a supply pipe which sequentially connects to a tap for supplying water to a sink, a basin or a bath. The shutoff valve can control the water flow and shut off the water flow to facilitate the replacement of a tap from a pipe. A conventional valve commonly employed in the industry is known as a corporation stop. The use of a corporation stop is required when the process water pipe cannot be drained to allow for maintenance. A corporation stop allows for repairs to be made while the water pipe remains full and pressurized.
In large agricultural irrigation systems, it is known to use remote-control valves to control water flow in different branches of a water distribution network. A remote-control valve in such an application typically employs a radio receiver for receiving control signals transmitted from a user-operated transmitter. The use of remote-control valves allows the operator of an irrigation system to control water distribution by opening and closing the valves from a distance without having to travel to the physical locations of the valves.
Nevertheless, remote-control valves used in irrigation networks buried underground tend to be fairly complex, large, and expensive and are therefore not suitable for typical yard and garden applications. So far, remote-control valves that are portable and sufficiently compact and easy to use so as to be suitable for yard and garden applications have not been available.
While prior art products exist in the filed of water shut-off valves, there remains a problem in that the valves may fail when called upon to close. Many rural and municipal water systems are located in remote areas and therefore may not be receptive to multiple RF signals transmitted thereto over a long distances. As a result, the valves may not be effectively opened and closed when desired.
Accordingly, a need remains for a corporation stop and shut-off mechanism for a water supply source that may be effectively operated by a user for overcoming the above-noted shortcomings.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide a remote operable corporation stop for enabling water to be more easily cutoff for various reasons including nonpayment and repairs. These and other objects, features, and advantages of the invention are provided by a system connectable to an existing water line for selectively controlling the flow of water therethrough. Such a system includes a housing positionable into a ground surface and spaced upstream a select distance from an existing water meter.
The housing has a plurality of openings for receiving a first water supply line with a first flow rate and directing a second water supply line with a second flow rate towards the existing water line wherein the second supply line is in fluid communication with the existing water meter. The housing may further include a lid removably connected thereto for allowing an operator to readily access the controlling and shut-off mechanisms (described hereinbelow) disposed within the housing.
Such a mechanism for shutting off water flow through the housing is disposed within the housing and contiguously connected to the first and second water supply lines. The shut-off mechanism further includes a motor operably connected to an actuator interface and includes a drive shaft extending outwardly therefrom. Such a drive shaft is rotatable in a select direction based upon the signal transmitted by the wand. The shut-off mechanism further includes an arm pivotally connected to the drive shaft that is movable along a select arcuate path.
Advantageously, the shut-off mechanism further includes a valve member secured to the arm that is caused to contemporaneously move with the arm during operating conditions so that the first and second water flow rates can be adjusted as desired by an operator. Such a valve member may be rotatable approximately one quadrant per 3 seconds to prevent a water hammer and air lock from occurring in the water main when the system is turned on and off, respectively.
Advantageously, the present invention further includes a mechanism for operably controlling the shut-off mechanism so that an operator can selectively control the first and second flow rates. The controlling mechanism is connected to the shut-off mechanism and is disposed within the housing, wherein the controlling mechanism includes a hand-operable wand for generating and sending a signal to the shut-off mechanism for toggling the system between open and closed modes.
The controlling mechanism further includes an antenna with a transceiver connecting thereto for transmitting and receiving a signal from the wand. The actuator interface electrically coupled to the antenna for processing the signal received from the wand and communicating such a signal with the shut-off mechanism during operating conditions.
The present invention further includes a power supply source passing through the housing that is connected to the controlling and shut-off mechanism respectively.
