< - Safety valve for ammonia
< - Function: to prevent excessive pressure. The safety valve is installed on the pipeline between the compressor exhaust chamber and the suction chamber.
< - Working principle:
< - The pressure of the safety valve spring and the suction pressure act on the lower valve disc, while the discharge pressure acts on the upper part. When the pressure is discharged When the sum of the safety spring pressure and the suction pressure exceeds a certain value, the valve disc opens, allowing the exhaust chamber to communicate with the suction chamber, and the exhaust pressure drops rapidly. The opening pressure setting value of the safety valve is: R and R are
