As a key component of the intelligent drainage system, the electrically controlled drain valve receives and processes electrical signals to control the drainage action, which involves the coordinated operation of precision electronics and mechanics.
First of all, the electrically controlled drain valve is usually equipped with a dedicated control circuit, in which the core component may be a microcontroller (MCU) or a specific integrated circuit chip. When an external electrical signal is input, such as a signal from a liquid level sensor, a command signal sent by a user through a remote control or a mobile phone application, these signals will be transmitted to the input end of the control circuit. The signal receiving module in the control circuit will identify and analyze these signals to determine their type and the information they carry, such as whether it is an instruction to open the drain, close the drain, or adjust the drain flow.
After receiving a valid signal, the microcontroller will process it according to the preset program logic. If it is an instruction to open the drain, it will send a corresponding drive signal to the drive module. The drive module generates enough electrical energy to drive the actuator of the drain valve according to the instruction from the microcontroller. If the drain valve adopts an electromagnetic drive method, the drive module will provide a suitable current to the electromagnetic coil to generate a magnetic field. This magnetic field will interact with the magnetic components inside the valve, overcome the force of the spring or other reset device, thereby driving the valve core to move, open the drainage channel, and realize the drainage action.
When processing the flow control signal, the microcontroller will accurately adjust the intensity or pulse width of the drive signal according to the set flow parameters. For example, by adjusting the current of the electromagnetic coil to change the magnetic field strength, the valve core opening can be accurately controlled to achieve precise regulation of the drainage flow.
During the whole process, the control circuit will also monitor the working state of the drain valve in real time. For example, the position of the valve core, drainage flow and other parameters are detected by sensors, and this information is fed back to the microcontroller. The microcontroller compares the feedback information with the preset working state. If an abnormality is found, such as the valve core movement is blocked and the drainage is not smooth, the drive signal will be adjusted in time or the alarm mechanism will be triggered to ensure the normal and stable operation of the drain valve.
In short, the electrically controlled drain valve realizes the precise control of the drainage action through a complex and orderly electrical signal reception, processing and feedback mechanism, which provides a solid guarantee for the efficient and reliable operation of the modern intelligent drainage system and meets the diverse needs of drainage control in different scenarios.
