Valve Knowledge: Note the use of back-pressure valve

Back-pressure valve in the course of precautions are:

    1, to avoid resonance with the system occurred.

    2, and pulsation damper used simultaneously, the pulsation damper to be an in between pumps and back-pressure valve in order to absorb the pump and back-pressure valve between the flow peak. Reduce the wear rate of back-pressure valve.

    3, outdoor use should be added protective shelter or protective cover.

    4 pairs of back-pressure valve prior to any maintenance, should stop functioning equipment, the release of pressure, close the back-pressure valve valves associated with the system, while recognizing that there is no pressure pulsation damper. Maintenance attention to prevent harm to human body fluids are transported.

    5, if the back-pressure valve counter-export access, back pressure will grow exponentially, bringing harm to the system and may be dangerous.

    6, running back-pressure valve was found to be promptly cut off the power supply failure.

    Warning: The back-pressure valve prior to any maintenance, should stop functioning equipment, the release of pressure, close the back-pressure valve valves associated with the system, while recognizing that there is no pressure pulsation damper. Maintenance attention to prevent harm to human body fluids are transported.
