The internal structure of a smart water meter is complex. In order to ensure the normal operation of the water meter, each component needs to work in coordination with each other. The actuator is one of many parts of the smart water meter. Knowing the working principle of the actuator is the key to dealing with simple problems about smart water meters. First of all, Henan smart water meter manufacturers explain to us the working principle of actuators in smart water meters.

The more popular actuators on the market are: motor pilot valve, electromagnetic pilot valve, plane stack valve, motor ball valve. The working principle of each actuator is different. First of all, the motor pilot valve uses the principle of a speed reduction mechanism. The magnetic drive principle is used to open and close the pressure relief hole to solve the problem of sealing the moving parts. It is similar to the electromagnetic pilot valve in principle, but it is slower than the electromagnetic pilot valve in time and response speed. The electromagnetic pilot valve is the pressure relief of the valve seal pressure chamber when the solenoid valve is opened, causing the water pressure in the pipeline to push the valve seal open, and the smart water meter works normally; when the solenoid valve is closed, the pressure relief chamber is closed. At this time, the water pressure in the cavity on the valve seal rises rapidly until the valve seal is pressed against the valve port, and the water outlet is closed. Working principle of flat stack valve: The speed of the motor is slowed down by the reduction mechanism, and the torque is increased to push the flat stack valve to rotate to achieve the function of opening and closing. The tightness is ensured by the hydraulic pressure. Motor ball valve working principle: The speed of the motor is slowed down by the reduction mechanism, and the torque is increased to push the ball valve to rotate to achieve the function of opening and closing.
