Main functions and functions of pressure valve of Atlas Copco industrial air compressor:
Pressure regulation: By sensing changes in system pressure, the valve opening is automatically adjusted to stabilize the compressor discharge pressure within the set range, meeting the pressure requirements of downstream gas equipment.
Safety protection: When the system pressure exceeds the safety threshold, the pressure valve will automatically open to relieve pressure, preventing equipment damage or safety accidents caused by overpressure.
Unloading and loading control: In conjunction with the compressor control system, achieve the switching between loading (starting gas production) and unloading (stopping gas production) of the unit, avoid frequent start stop, and extend equipment life.
Common structures and components:
The structure of a pressure valve is usually designed based on the compressor model and pressure rating, and generally includes:
Valve body and valve core: The core control components achieve pressure regulation through the movement of the valve core.
Spring component: provides reset force and determines the pressure setting value.
Sensing components, such as diaphragms or pistons, sense changes in system pressure and drive valve spool action.
Sealing element: Ensure airtightness when the valve is closed to prevent pressure leakage.
Adjustment knob or bolt: used for on-site calibration of pressure setting values.
