working principle

The safety valve is an on-line adjustable pressure automatic control valve, with a scale line of opening pressure range, which can adjust the required take-off pressure value on-line according to different working conditions. A specific pressure is calibrated by adjusting the compression spring of the regulating cover. The calibration pressure is the maximum safety pressure set to avoid damage to the pipeline equipment. When the pipeline pressure is greater than the calibration pressure of the safety valve, the valve seat will automatically spring up, and the pressure in the pipeline system will be released, so as to protect the pipeline and equipment.
