摘要： A valve control system includes a rotatable valve operably coupled to a motor, a valve position indicator configured to rotate with the rotatable valve, at least two sensing devices configured to detect the valve position indicator, and a controller. The at least two sensing devices include a home position sensing device and an end-of-travel position sensing device. The controller includes valve state determination logic having circuitry configured to monitor a status of a home indicator and an end-of-travel indicator of the rotatable valve, determine a commanded direction of movement of the rotatable valve, monitor the status of the home indicator and the end-of-travel indicator before a valve rotation stop is commanded and after the valve rotation stop is commanded, and determine a current state of the rotatable valve based on the commanded direction of movement and at least one of the status of the home indicator and the end-of-travel indicator.

摘要： A micro-metering device with a constant flow rate, including a rotary shear valve, a mounting seat, a rotation drive assembly, an injection drive assembly and a controller. The rotary shear valve includes a valve main body and a valve spool. The valve main body is provided with a main flow channel and a plurality of branch flow channels. The valve spool is rotatably arranged inside the valve main body, and is configured to communicate the main flow channel with different branch flow channels. A pressure sensor is provided inside the valve main body, and is communicated with the main flow channel. The pressure sensor is configured for detecting a pressure inside the main flow channel. Whether the switching of the liquid path is correct is determined according to the pressure in the main flow channel.

摘要： Disclosed is an HVAC (heating, ventilation and air-conditioning) system which comprises a fluid flow duct (1), a fluid flow valve (7) which is arranged therein and has a valve body (5) in the fluid flow duct (1) and a valve motor (15) which moves the valve body (5), a control circuit for activating the valve motor, a sensor (8) in the fluid flow duct (1) and an evaluation module for evaluating signals of the sensor. To produce an automated functional control, the following procedure is adopted: a first actuation signal is preset for the valve motor by the control circuit, and the actuation signal corresponds to a first setpoint position of the valve body (5), registration of a first signal of the sensor (8) by the evaluation module, and determination of a functional diagnosis of the fluid flow valve on the basis of the first signal of the sensor.
