BACKGROUND OF THE INVENTION
Ball Valve's has been the most successful and outlasting valves compared to any other valve in the world. A ball valve is a quarter turn valve that uses a perforated pivoting ball to control the flow through it. Over time, ball valves have been utilized for air, water, gas, and oil. Other valves failed to last because of the wear and tear of the diaphragm, needle, springs or poor construction. This mostly occurs from a particular valves repetitious use. Ball valves are preferred because of the excellent seal it provides and its increased resistance to wear. Also, ball valves are utilized because the “valves not made to extend vertical and are smaller in diameter compared to other rotary valves.
The Stepper Motor is a brushless and DC operated electromagnetic apparatus that converts digital pulses into a mechanical shaft rotation. Stepper motors divide a full rotation into a certain number of steps and can range from micro stepping to full stepping procedures. Stepper motors also allow precise positioning control without the need of a feedback system as well as being capable of continuous rotation.

FIG. 1-A Illustrates two of the main embodiment of the invention. As shown, a “Stepper Valve” includes a stepper motor, a ball valve, an emergency manual shutoff, and a drive shaft. These are 5 of the major components that make up the “Stepper Valve”. The “Stepper Valve was designed to last with no interchangeable parts. There's no diaphragms, no washers to ever change, or no needles or wore out springs to change or replace. You can control either “Stepper Valve” by means of the “Stepper Valve Controller” or any other system that can control a stepper motor. The “Stepper Valve” Controller” is optional, which is programmed to operate the “Stepper Valve's” full operation. FIG. 1-A illustrates the “Stepper Valve” used for indoor/outside use. It can be Used to control any and all water faucets in your home/office kitchen or bathroom. Other specific areas that the “Stepper Valve”. “Stepper Valve” and controller (or the “Stepper Valve” alone) can be utilized for range from following: Precisely regulate inside water distribution, Main line automatic shut-off, all water shutoff and regulation solutions, precisely regulate any and all gas measurements (or automatic gas shutoff/turn on), also can precisely measure and regulate air pressure), and multiple other system uses. FIG. 1-B illustrates the “Stepper Valve” used for outdoor use. The “Stepper Valve” and controller (or the “Stepper Valve” alone) can be utilized from a range of the following: Precisely regulate outside water distribution, water hose (hose bib), Water Mist distribution system(plants), and multiple other system uses.

FIG. 2B display the “Stepper Valve” assembled with emergency shut-off (5). This diagram depicts the parts used to make the apparatus functional. This particular “Stepper Valve” is designed for indoor/outdoor use. The stated “Stepper Valve” was created with a unipolar or bipolar stepper motor (1), a precisely ratio gearbox (2), and a ball valve (4). The gearbox is assembled to the shaft of the stepper motor. The gearbox (2) shaft is then connected to a machined cylinder housing, the coupling/driveshaft (3), to join the gearbox (2) shaft to the ball valve (4). The coupling/driveshaft (3) which is then secured to both sides (the gearbox and the ball valve (4)) by machined screws. This was done to create smoother operations and maximum torque delivery. In order to turn the ball valve (4) to a precise angle, the stepper motor (1) turn ratio had to be changed to a smaller step size. For this to work a gearbox (2) had to be implemented to decrement the step ratio from 1.8 degrees to 0.018 degrees' step size.

FIG. 4 Illustrates one embodiment of the invention, as shown, you see a microcontroller, a full h-bridge motor driver (14), control switches (7,8,9,10,11), and a UART system (13) to provide control from wired and/or wireless communication. Other communication, such as, I2C, SPI, and any other system that is invented within the time span of this patent can also be utilized with the “Step Valve”. Wireless communication ranging from, IR, Bluetooth, ZIGBEE, AND XBEE will be utilized to transmit and receive data from UART (13). A Bipolar Stepper motor has to use a full h-bridge (14) in order to operate. This is because the coils of the bipolar motor (15) have to switch polarity every single step that it takes to achieve the next step. The microcontroller (12) used can be any microcontroller but as seen, the microcontroller (12) is an 8-bit processor. The microcontroller (12) controls, motor speed, motor rotation, saved step data, and full control of the “Stepper Valve”. The buttons (7, 8, 9, 10, and 11) in the picture are there for the purpose of depicting switches. The motor controller (14) will be operated by voice commands, touchless sensing, touch screen, and/or push buttons. The Increment switch (7) will allow the user to adjust the “Stepper Valve” step by step in the on position until the user has reached their preference. The decrement switch (9) will allow the user to adjust the “Stepper Valve” in increments towards the off position until the user has reached their preference. By pressing the off switch (8) once, this will allow the user to fully close the valve despite its position. The speed switch (10) is used to adjust from the various different motor speeds programmed to the microcontroller (12). The speed switch (10) was created to control how fast or slow you want the “Stepper Valve” rotation speed. The save switch (11) was added if the user has a pressure/valve position that he/she would like to be saved for future operation.
FIG. 5 Illustrates one embodiment of the invention, as shown, you see a microcontroller (12), Darlington Pair IC driver (16), control switches (7, 8, 9, 10, 11), and a UART (13) system to provide control from wired and/or wireless communication. Other communication, such as, I2C, SPI, and any other system that is invented within the time span of this patent can also be utilized with the “Step Valve”. Wireless communication ranging from, IR, Bluetooth, ZIGBEE, AND XBEE will be utilized to transmit and receive data from UART (13). This specific “Stepper Valve Motor Controller” was invented because a Unipolar Stepper (17) can be operated by using A basic transistor, Darlington Pairs, or Drivers that utilizes Darlington Pairs (16). Reason being is because the coils of the Unipolar Stepper motor (15) does not switch polarity every single step that it needs to achieve. Instead, the Unipolar Stepper Motor (17) has a center tap That is energized by the power source, and do to that, all the Stepper motor needs to operate is a latched ground switch of the same power source of the “STEPPER VALVE”. Which is why the Darlington Pair IC (16) was utilized in Unipolar operation. The microcontroller (12) used, can be any microcontroller, but as illustrated, the microcontroller (12) is a 8 bit processor. The microcontroller controls, motor speed, motor rotation, saved data, and full control of the “STEPPER VALVE”. The buttons (7, 8, 9, 10, 11) in the picture are there for the purpose of depicting switches (only used in example). The “Stepper Valve Motor Controller” can and will be operated by, voice commands, touchless sensing, touch screen, and/or push buttons. The Increment switch (7) will allow the user to, adjust the “STEPPER VALVE” step by step in the on position, until the user has reached their preference. The decrement switch (9) will allow the user to, adjust the “STEPPER VALVE” step by step in the off position, until the user has reached their preference. The off switch (8) will allow the user to shut the valve off completely. By pressing the off switch (8) once, this will allow the user to fully close the valve despite its position. No matter what position it's in, the “STEPPER VALVE” will turn off completely. The speed switch (10) is to adjust from the various different motor speeds programmed to the microcontroller (12). The speed regulation switch (10) was set to control how fast or slow you want the “STEPPER VALVE” rotation speed. The save switch (11) was added for if the user has a pressure/temperature that wants to be saved for normal operation.

The “Stepper Valve Motor Controller” will be equipped with multiple controller options to choose from. According to various embodiments the “Stepper Valve Motor Controller” is assembled with a power supply, a microprocessor/microcontroller (12), and a motor driver. The motor driver (14 or 16) is used to control the Step valves in multiple step angles. It also has multiple controls to save how much water, air, gas, or liquid, the user wants to output from the apparatus. The “Stepper Valve Motor Controller” can be operated by physical buttons or any ways of wireless communication, for example: Bluetooth or Wi-Fi. The “Stepper Valve” can also be controlled using a voice command control, an electronic switch, or a motion sensor. The motor controller can accurately and precisely count each step that the “STEPPER VALVE” is given which gives the consumer the power to accurately and precisely measure pressure, mix temperatures, mix chemicals (dry or liquid), mix air/fuel ratio, or to turn “Stepper Valve” on or off automatically.

The said “Stepper Valve Motor Controller”, for any and all e“Stepper Valve's”. can look exactly the same on the outside. The difference is the integrated circuit driving the motor. The Bipolar “Step Valve” use a h-bridge controller (14), while the Unipolar uses a transistor/Darlington Pair (16). All control's will operate the exact same whether unipolar or bipolar “Stepper Valve”. The Bipolar “Stepper Valve” is for higher torque operations. The Unipolar “Stepper Valve” is for Higher speed.

The “Stepper Valve Motor Controller” will be equipped with multiple controller options to choose from. According to various embodiments the “Stepper Valve Motor Controller” is assembled with a power supply, a microprocessor/microcontroller (12, and a motor driver (14 or 16). The motor driver (14 or 16) is used to control the Step valves in multiple step angles.

All control's will operate the exact same whether unipolar or bipolar “Stepper Valve”. The Bipolar “Step Valve” is for higher torque operations. The Unipolar “Stepper Valve” is for Higher speed.
FIG. 8 illustrates a Block Diagram of the ““Stepper Valve” and “Stepper Valve Motor Controller” circuit according to various embodiments of the invention. Many Stepper motors operate at various speeds and will output a certain amount of torque. Most voltages that the “Stepper Valve” will operate within is between the ranges of 5 to 24 volts. Depending on the Type of ““Stepper Valve” being used will determine the “Stepper Valve” voltage supply needs. Depicted in (FIG. 1-A), If “Stepper Valve” “FIG. 1-B” was utilized for a water hose bib, the torque needed to rotate the ½ inch or ¾ inch ball would need a 5 volt 0.17-amp Dc power supply to operate the “Stepper Valve”. For instance, if the ball valve took 31 Lbs. per newton meter to effectively rotate the valve, the stepper motor needed would need to output at least twice the amount of torque as the ball valve needs to operate.
