    Basic Information
    Because of the inbalance of gas usage during anaerobic fermentation and the process of biogas exhausting, the air pressure can be increased over 2000Pa and would bring detriment to the safety of the equipment including assembled tank, integrated assembling tank, double membrane gas tank, wet gas holder etc. The main fuction of the positive and negative pressure protector is to protect the equipment from abnormal working conditions, to eliminate the excessive pressure or negative pressure, so as to ensure the safety of the equipment operation.
    The positive and negative pressure protector is a kind of safety protector installed on biogas fermentation tank. When the positive or negative pressure of tank exceeds the limit, the protector could act to prevent occurrence of safety accidents. When positive pressure of tank exceeds the limit, the protector could act to relieve the pressure to prevent explosion of tank and when negative pressure of tank exceeds the limit, the protector could act to prevent the tank from being crushed by atmospheric pressure.
