Air volume control valve actuator (manual type)

The air volume control valve actuator (manual type) is a key device for adjusting and controlling air volume, especially playing an important role in HVAC systems. The following is a detailed introduction to the air volume control valve actuator (manual type):

I. Basic Overview

Definition: The air volume control valve actuator (manual type) is a device that changes the opening of the valve by manual operation to achieve the adjustment and control of the air volume. It is usually used in conjunction with the air volume control valve and is an indispensable part of the ventilation and air conditioning system.

II. Composition structure

The air volume control valve actuator (manual type) is mainly composed of the following parts:

Shell: It is usually stamped and formed by steel plate and sprayed on the surface. It has a beautiful appearance, is strong and corrosion-resistant, and has a long service life.

Actuator: The manual actuator mainly includes mechanical transmission parts such as handwheels and connecting rods. The connecting rod is driven to move by manually rotating the handwheel, thereby changing the opening of the valve.

Seal: Including elastic elements such as rubber gaskets and O-rings and non-elastic elements such as metal gaskets, which are used to ensure the sealing performance of the valve.

Blade: The blade is the key component of the air volume control valve, and the air volume is adjusted by changing the angle or position of the blade.

3. Working principle

The working principle of the manual air volume control valve actuator is relatively simple, and the air volume is adjusted mainly through the following steps:

Manual operation: The user drives the connecting rod to move by rotating the handwheel.

Transmission mechanism: The connecting rod converts the rotational motion into the linear motion or angle change of the blade.

Air volume adjustment: As the angle or position of the blade changes, the opening of the valve also changes accordingly, thereby adjusting the air volume.

4. Scope of application

The air volume control valve actuator (manual type) is widely used in various occasions where precise control of air volume is required, such as:

Ventilation system of industrial and mining enterprises

HVAC system of civil buildings

Laboratories, hospitals and other places that require special air environment

5. Precautions

Installation and maintenance: Ensure that the air volume control valve actuator (manual type) is correctly installed and regularly maintained to ensure its normal operation and extend its service life.

Operation specifications: During use, relevant operation specifications and safety regulations should be observed to avoid equipment damage or safety accidents caused by improper operation.

Environmental adaptability: When selecting an air volume control valve actuator, it is necessary to consider the characteristics and requirements of its working environment to ensure that the equipment can work normally and meet the use requirements.

In summary, the air volume control valve actuator (manual type) is one of the indispensable and important equipment in the ventilation and air conditioning system. By understanding its composition structure, working principle, scope of application, and purchase precautions, you can better select and use this equipment.
