Damper Valves Uses in Air Circulation and Ventilation Systems
Damper valves are extremely important components of any air circulation system. Valves are devices that control the direction of flow, whether liquid or gas. Damper valves control how much of that material, usually gas, is allowed to pass through a given system. They operate similar to the water valves outside your house, or pressure valves that keep gas pressure in check.
There is a huge variety of damper valves available today because they are used in so many different systems. Damper valves are found cars, dryers, chimneys, stoves -- anything that involves air flowing through a pipe or a vent, a damper valve can be used inside it. Some damper valves function automatically: they work when favorable air applies pressure and opens the gate so it can escape. Conversely, the gate closes when unwanted air from outside tries to flow in. A damper valve can turn any air system into a one-way circuit. You can also find manually adjustable damper valves.
The most popular kind of damper valves are blade dampers and butterfly dampers. Blade dampers use slats to influence the direction air travels. They are arranged in a manner similar to horizontal blinds in front of windows that you can tilt upwards or downwards by twisting a rod. When angled a certain way, air can flow in only one direction. This keeps air moving out of a given facility while outside air is blocked and kept outside. These can be found on many industrial sites, including those manufacturing for the chemical, steel, cement, pharmaceutical, iron and food stuff industries.
Butterfly dampers, usually lightweight and fairly cheap, control the flow of gas through a pipe system with the use of a circular piece of material, which can be metal or plastic, that spins around to block off air system or let air through. It rotates on a vertical axis in the same manner as a quarter spun on a tabletop. When the "door" is open, air can pass through. When closed, air is kept at bay. These damper valves can be used to prevent fires or explosions in environmental systems and fire prevention systems. A sensor connected to the butterfly damper can detect smoke or poisonous gas. When it does, it immediately halts the flow of air before it reaches the combustion chamber. If fire is already spreading, fire damper valves will save the day. In event of a fire, a temperature fuse picks up on the increased heat and closes the valve to slow the spread of fire and smoke.
Damper valves can be made of any sort of material, including stainless steel, galvanized steel, carbonized steel, plastic and/or aluminum. They are crucial components of any air or gas ventilation system that requires circulating air. Damper valves come in all shapes and sizes, from the industry-ready blade dampers to the smaller, lightweight butterfly dampers. Custom dampers can be designed by most providers to service a specific system. Whether they're keeping outside air out of your car or the allergen-heavy spring air from entering your chimney (while still allowing smoke to leave your house), damper valves keep our air systems clean.
