1. Field of the Invention
The present invention relates to an electronic water utility safety apparatus and more particularly pertains to terminate the water feed to a house when the pressure thereof varies from a predetermined range.
2. Description of the Prior Art
The use of water control devices of various designs and configurations is known in the prior art. More specifically, water control devices of various designs and configurations heretofore devised and utilized for the purpose of precluding the flow of water through a house when desired parameters are not met through various methods and apparatuses are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
By way of example, the prior art discloses in U.S. Pat. No. 4,742,841 to Vonderhaar et al, discloses a water shut-off valve.

Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved electronic water utility safety apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the new and improved electronic water utility safety apparatus, is comprised of a plurality of components. Such components in their broadest context include a control box, a light emitting diode, a buzzer, a first electrical line, a second electrical line, a sensor, a valve and an electrical circuit. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
More specifically, the central component of the system 10 is the control box 12. Such control box is for operating the system in an intended manner. It is preferably positioned within the house 14 of the user. In this manner, it may be monitored at a most convenient location.
Located within the control box is a light emitting diode 16. Other visible displays are acceptable. The function of the light emitting diode display is to indicate a sensed water pressure.
Also located on the control box is a buzzer 18. The buzzer is mounted in the control box. It functions to generate an audible signal in the event that the pressure is identified in a water line outside of the house which is identified as being outside of an acceptable range of pressure.
Extending downwardly from the control box is a first electrical line 20. Such electrical line extends from the control box to a source of potential 22. Such source of potential is preferably located within the house.
Next provided is a second electrical line 24 on the bottom of the control box 12. Such second electrical line extends from the control box to the water line 26 being sensed for changes and pressure.
In association with the second electrical line 24 and the water line 26 is a sensor 28. Such sensor is mounted on the second electrical line at the water line. The function is to determine the pressure within the water line. This is to then allow the light emitting diode display to disclose to someone viewing the control box what the determined pressure is as determined by the sensor. Also located in the water line adjacent to the sensor is a valve 30. Such valve is located within the water line adjacent to the sensor. Its function is to shut off the flow of water upon the pressure being outside of the acceptable range. Consequently, when the pressure is outside of the range as determined by the sensor and displayed by the light emitting diode display, an electrical circuit within the box will control the functions of the box and switch the orientation of the valve 30 to shut off all flow of water due to an unacceptable situation arising from the pressure within the water line.
An apparatus which can be installed in the main water service pipe to monitor and display water pressure and discontinue flow if an emergency requires. It is comprised of a solenoid actuated valve and a pressure sensor control unit. The valve is mounted directly within the pipe in the same fashion as the existing main control valve in the system. The control unit features a digital display and houses the pressure sensing components. It is wired to the solenoid but can be remotely mounted near an entry/exit to the building or dwelling. The entire system is powered by standard AC house current at 110 to 120 volts.
The pressure within the pipe is constantly monitored by, and displayed on, the control unit. Should the pressure fluctuate beyond predetermined limits, the solenoid will be energized, and the valve will close. Hence, if the system developed a leak, a pressure drop will occur, and flow will be discontinued. Inversely, a higher than normal pressure will shut off water flow. Both of these events will occur with the control unit set top the automatic mode. It can also be controlled manually from the keyboard without the need for any special techniques. The idea is simple but very effective. The building, and all of the articles therein, will be effectively protected against water damage whether or not anyone is present. This system will be especially valuable to those who find it necessary to be away temporarily, such as on vacation.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
