Operating Principle of Electric Valve

The electric valve consists of two parts, part electric actuator and part valve. The valve switch power comes from the electric actuator. Because the electric valve is more convenient to use, it can be used with the power supply, compared with the amount of automatic control valves compared with other driving methods. The working principle of electric valve is that the motor to produce linear motion and angular rotation motion under the action of electric signal.

Electric valve mainly has two switch type and regulation type according to the equipped actuator. Switched electric valve is used for opening and closing in the working condition pipeline, and the main function is to cut off or turn on the pipeline medium. The regulating electric valve can accept the signal from the control system, and adjust the opening of the valve to achieve the purpose of regulating the flow and pressure of the pipeline medium.

Components of Electrically Valves

01/

Electric Motor: The actuator is equipped with an electric motor that changes electrical energy into mechanical rotational motion. The motor is typically a brushless DC motor or an AC motor.

02/

Output Shaft: The actuator’s output shaft is connected to the valve stem or actuator mount. As the motor rotates the output shaft, it transfers the motion to the valve, causing it to open or close, depending on the required operation.

03/

Gear Mechanism: The rotational motion of the electric motor is transmitted to a gear mechanism, which converts the high-speed rotation of the motor into a lower-speed, higher-torque output. This gear mechanism provides the necessary power to actuate the valve.

04/

Limit Switches: Electrically valves often incorporate limit switches. These switches are positioned to detect the valve’s fully open and closed positions. When the valve reaches these positions, the limit switches send signals to the actuator control system, indicating the valve’s status.

05/

Control System: The control system of the actuator receives signals from an external control source, such as a Programmable Logic Controller or a control panel. These signals dictate the valve’s desired position or degree of opening/closing. The control system then processes these signals and sends appropriate commands to the electric motor to drive the actuator in the required direction.

06/

Feedback Mechanism: Electrically valves often employ feedback to ensure accurate valve positioning. This mechanism consists of position sensors, such as potentiometers or encoders, that provide continuous feedback on the valve’s actual position. The control system compares this feedback with the desired position and adjusts the motor’s operation accordingly to achieve precise control over the valve position.

How To Operate And Maintain The electrically valves During Operation

The regulating valve is a field instrument, and the ambient temperature is required to be in the range of -25 to 60 °C, and the relative humidity is ≤95%. If it is installed in the open air or in high temperature places, waterproof and cooling measures should be taken. Where there is a vibration source, keep away from the vibration source or increase anti-vibration measures.

The regulating valve should be installed vertically in general, and can be tilted under special circumstances. For example, when the tilt angle is large or the valve itself has too much weight, the valve should be protected by a support.

Generally, the pipeline where the regulating valve is installed should not be too high from the ground or the floor. When the height of the pipeline is greater than 2 m, a platform should be set up as much as possible to facilitate the operation of the handwheel and facilitate maintenance.

Before installing the regulating valve, the pipeline should be cleaned to remove dirt and welding slag. After installation, in order to ensure that impurities do not remain in the valve body, the valve should be cleaned again, that is, all valves should be opened when the medium is introduced to prevent impurities from getting stuck. After using the handwheel mechanism, it should return to the original neutral position.

In order to make the production process continue in the case of failure or maintenance of the regulating valve, the regulating valve should be equipped with a bypass pipeline.

FAQ

Q: What is the meaning of electronic valve?

A: The so-called electric valve, as its name implies, is to drive the opening and closing of the valve through the power. U type flange butterfly valve (6) supply. It is mainly composed of two parts. The upper part is an electric actuator and the lower part is a valve.

Q: What are electrically operated valves called?

A: Solenoid-actuated valves are electrically operated. They rely on a solenoid to open or close the valve, making them highly responsive and suitable for applications that require rapid changes in fluid flow. They are often used in automated systems and remote control applications.

Q: How does an electric valve work?

A: Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring.

Q: What kind of valve is electrically driven?

A: These are simply called Direct-Acting solenoid valves. When electricity is supplied, electrical energy is converted to mechanical energy, physically moving a barrier to either obstruct flow (if it is N.O.) or allow flow (if it is N.C.).

Q: What are the two main types of electrically operated valves?

A: The most common electric valves are electric actuated ball valves and electric actuated butterfly valves, although electrically actuated gate valves or sluice valves are often used in larger pipe sizes.

Q: What is the difference between electric valve and solenoid valve?

A: Solenoid valves consume more power to operate than electric ball valves. Typically, solenoid valves require power to open or close and more power to hold the valve in its energized state. Electric ball valves, though, only use power to open or close and don't require power to stay in that position.

Q: Is a electrical valve an actuator?

A: Often valves and actuators are mistakenly considered to be the same thing, but in fact, they are two very different components. While a valve is used to control the amount of fluid or gas flowing through a pipe, it must either be set in a specific position or manually controlled.

Q: Why is my electric valve not working?

A: These issues often stem from debris, damaged parts, or electrical problems. Fixes include cleaning, replacing damaged components, and repairing electrical or cooling systems. These failure modes apply to all kinds of valves, such as 2 way and 3 way valves.

Q: Is a solenoid and valve the same thing?

A: A solenoid is a wire coil that acts as an electromagnet, and in a valve system, the solenoid controls the current through the valve. In its resting state, a (normally closed*) solenoid valve is closed with a plunger blocking the opening.

Q: What is the difference between pneumatic and electric valves?

A: Electric valve actuators are suitable for applications that require precision, feedback, and digital control, such as modulating valves or complex systems. In contrast, pneumatic valve actuators are better for applications that require speed, torque, and safety, such as on-off valves or harsh environments.
