Smart Valve and Related Control Method

摘要

A smart valve and the related control method to solve the problem of energy waste in current heating and air-conditioning systems due to the inconvenience of valve adjustment. The smart valve is constructed with the valve body, the valve stem, and the internal valve spool located inside the body of the valve. The specialty of the smart valve is its inclusion of controller, pressure differential transducer, display monitor and the keypad that can enter certain flow rate and operating information to the controller. The illustrated Actuator, pressure differential transducer, display monitor and the keypad are all connected with the controller. The controller is able to receive the parameter settings entered by the keypad and the pressure differential detected by the pressure differential transducer, and will process and send certain movement instructions to the actuator to drive the movements of the valve stem.

1. A smart valve comprising:
a valve body; a valve stem; an internal valve spool located inside the valve body; an inner end of the valve stem connected to the valve spool; an outer end of the valve stem extends outside of the valve body and is connected with an actuator (1) that drives its movements; a controller (2); a pressure differential transducer (3); a display monitor (4); and a keypad (5) that can enter certain flow rates and operating information into the controller (2); wherein the actuator (1), the pressure differential transducer (3), the display monitor (4), and the keypad (5) are all connected with the controller (2), the controller (2) capable of receiving setup parameters entered by the keypad (5) and a pressure differential sensed by the pressure differential transducer (3), and will process and then send certain movement orders to the actuator (1) to drive the actions of the valve stem.
