AI Technical Summary
In compressed air systems, natural gas transportation, and chemical production, tiny magnetic metal impurities such as iron filings and welding slag can easily scratch the throttling valve core, leading to internal leakage, reduced regulation accuracy, and incomplete closure, thus affecting service life and system reliability.
A protective mechanism is installed at the air inlet of the heat exchanger, including a housing, a filter cylinder, a slide groove, a bayonet, a fixing plate, an operating rod, and a magnetic rod. The filter cylinder filters impurities, and the magnetic rod attracts iron filings to prevent impurities from entering the throttle valve.
It effectively prevents impurities from scratching the valve core, thus improving the service life of the throttle valve and the reliability of the system.
