Function of PP Plastic Damper Valve:

The primary function of a damper valve is to regulate the flow of air within a ventilation system. It allows for the adjustment and control of air volume, ensuring proper air distribution throughout the system. By modulating the position of the damper, the airflow can be increased, decreased, or completely shut off, depending on the requirements of the space being ventilated.

Dampers for Precise Flow Control:

When precise flow control is necessary, specialized dampers come into play. These dampers are designed to provide accurate and fine-tuned adjustments to the airflow. They offer enhanced control over the volume and velocity of air, making them suitable for applications where precise airflow management is crucial, such as laboratories, cleanrooms, and industrial processes.

Difference between a PP Plastic Damper and a Valve:

While the terms “damper” and “valve” are sometimes used interchangeably, they have distinct characteristics. A damper is specifically designed for airflow control within ventilation systems. It regulates the flow of air by adjusting the position of a blade or plate. On the other hand, a valve is a broader term that encompasses various devices used for controlling the flow of fluids or gases. Valves are commonly found in plumbing systems, industrial processes, and other applications beyond ventilation.

Introduction to Butterfly Damper:

A butterfly damper is a specific type of damper characterized by its disc-shaped, butterfly-like blade. This blade is connected to a central spindle, allowing for 90-degree rotation. By rotating the blade, the airflow can be controlled effectively. Butterfly dampers are commonly used in HVAC systems, where quick and reliable airflow modulation is required.

Three Types of PP Plastic Dampers:

  1. Parallel Blade Dampers: These dampers feature parallel blades that move in unison to adjust the airflow. They are suitable for applications requiring basic flow control.
  2. Opposed Blade Dampers: In opposed blade dampers, the blades move in opposite directions. This design allows for precise modulation of airflow and is commonly used in applications requiring accurate control.
  3. Single Blade Dampers: Single blade dampers have a single blade that pivots to control airflow. They are ideal for applications where space is limited or a compact design is required.

Applications of Pressure Relief Damper:

Pressure relief dampers are specifically designed to relieve excess pressure within a ventilation system. They are commonly used in areas where pressure imbalances may occur, such as commercial kitchens, laboratories, or industrial facilities. These dampers help maintain proper airflow and prevent damage to the system caused by excessive pressure.

Conclusion:
PP plastic dampers play a vital role in ventilation systems, ensuring efficient airflow and maintaining optimal environmental conditions. Understanding their function, types, and applications is crucial for designing and implementing effective ventilation solutions. Whether it’s precise flow control, the difference between dampers and valves, the versatility of butterfly dampers, or the need for pressure relief, these aspects contribute to the overall efficiency and performance of ventilation systems.

The ventilation damper is a device used to regulate the airflow through a ventilation system. They can be installed in ductwork, ventilation fans and air handling units to control the direction and volume of airflow. The preparation and application of a ventilation damper involves several steps, as described below:

Preparations before making the ventilation damper:

Determine the installation location: The first step in preparing to install the ventilation baffle is to determine the installation location. This will depend on the specific requirements and materials of the ventilation system. If the installation location needs to meet fire protection standards, a fire protection ventilation damper must be installed. In aggressive environments, the corrosion resistance of ventilation dampers must be taken into account.

Choose a damper type: There are several types of ventilation dampers, including leaf dampers, louver dampers, and butterfly dampers. The type of damper selected will depend on the specific requirements of the ventilation system, including the volume and direction of airflow. If there is a high airtightness requirement for the damping valve body, it is necessary to test the sealing performance of the air valve.

Sizing the damper: The size of the damper will depend on the size of the ductwork or ventilation fan that will be installed. It is important to make sure the damper is the correct size to avoid air leakage and reduce noise.

Determine damper material: Vent dampers can be made from a variety of materials, including galvanized steel, aluminum, stainless steel, and plastic. The material selected will depend on the specific requirements of the ventilation system, including temperature and humidity levels. The lowest production cost is plastic ventilation damper, which is widely used in laboratory ventilation system and factory exhaust system. The production cost of stainless steel ventilation damper is high, and it can be used in engineering projects of high-end hotels and office buildings.

Ventilation dampers use:

Installation: Vent baffles should be installed according to the manufacturer’s instructions. The damper should be fastened tightly to the ductwork or ventilation fan to prevent air leakage. Pay attention to the installation direction and connection method of the damper during installation.

Adjustment: Once the damper is installed, it should be adjusted to regulate the flow of air through the ventilation system. This can be done by adjusting the blades or louvers of the damper to increase or decrease the air flow. Adjustment testing must be performed in strict accordance with engineering acceptance criteria.

Maintenance: It is important to maintain your ventilation damper regularly to ensure it continues to function properly. This may include cleaning the blades or shutters of the damper to remove dirt and debris, and lubricating all moving parts to prevent wear. Effective maintenance can prolong the service life of the ventilation damper and reduce the occurrence of unexpected accidents.

Laboratory piping system installation

To sum up, when choosing a suitable damper for ventilation, it is necessary to purchase according to the actual requirements and standards, and the manufacturer of the ventilation damper will customize the production according to the specific standards of the buyer. The ventilation damper in the ventilation duct system is the main air volume control unit, combined with the temperature sensor and humidity sensor, it can precisely control the indoor air quality.

The air volume control valve has a basic structure: to place a (baffle plate) in the center of the air duct. The valve plate can rotate around an intermediate shaft parallel to the valve plate. Become an electric multi-leaf air volume control valve.

Air volume control valves are generally divided into the following types:

(1) Electric air volume control valve

(2) Manual air volume control valve

(3) Venturi air volume valve

(4) Variable air volume butterfly valve

(5) Check valve

The constant flow function of the air volume regulating valve is realized by the contraction and expansion/contraction of the silicon capsule located in the middle of the balancer. The principle is that the built-in silicon capsule with the adjustable cross-sectional area can automatically adjust the cross-sectional area when the wind pressure and air volume change and keep the air volume stable in the wind pressure range 50-200pa and high pressure in the range of 150-600pa. There is no need for power control, no initial adjustment, no maintenance, 30-year service life, stable work under -10-60 feeding degree environment.

The air volume control valve has the following characteristics:

1. The role of water balance. The air volume distribution in various ventilation systems is reasonable, ensuring reliable fresh air distribution in different areas.

2. The function of energy-saving and precise control of air volume. On the premise of ensuring the fresh air volume, the system runs energy-saving and low-consumption

3. It is widely used in the industrial waste gas treatment industry, which can accurately control waste gas emissions and prevent the backflow of toxic waste gas.

4. The effect of reducing noise. It can effectively reduce wind noise and other noise in the air duct, especially in the exhaust system of industrial production and office buildings, replacing exhaust fans, significantly reducing noise, saving energy, and maintaining continuous ventilation.

The constant air volume regulator with nothing to do with the pipeline pressure is used in the central fresh air system and exhaust system to effectively ensure the continuous new air volume and exhaust volume effectively and accurately control the air volume and reduce noise. They are usually used in a large area in the air duct system of the central fresh air system and exhaust system of hotels, hospitals, office buildings, and other places to replace traditional manual valves and exhaust fans.

The air volume control valve has a range:

The electric air volume control valve is suitable for industrial waste gas treatment, civil building HVAC systems, ventilation equipment in school laboratories, and hospital ventilation and exhaust systems. It is one of the vital equipment to control ventilation modes in various environments. Its main features are flexible operation, low noise, small leakage (closed type leakage> 0.5%), wide operating temperature range, reliable structure, safe and convenience.
