Non-Retrun Damper
Non-Retrun Damper is a device used to control the direction of gas flow, applicable to air conditioning, ventilation, purification and other fields, can make the gas flow in one direction, and prevent the gas back flow. Non-retrun damper is mainly composed of valve body, valve wing, spring and other parts, when the direction of gas flow and the valve wing consistent, the valve wing will automatically open; when the direction of gas flow and the valve wing reverse, the valve wing will be subject to the force of the airflow, and automatically closed.
Overview
Application:
Non-retrun damper is mainly used in ventilation system, air conditioning system, purification system, can prevent indoor air pollution, prevent equipment backflow and gas confusion, to ensure the effective operation of the system. Non-retrun damper is widely used in the purification environment with strict requirements and plays a very important role.
Working Principle:
When the airflow flows in the forward direction of the check air valve, the valve wing will push from the airflow and open the valve, allowing the gas to flow freely and unimpeded.
The spring on the valve wing will keep a certain tension to make the valve wing open under the pressure of the airflow, and when the airflow stops or flows in the reverse direction, the spring will pull the valve wing back to its original position to close the valve, preventing the gas from flowing backward, and playing the role of preventing backflow and protecting the equipment.
