The adjustment and maintenance of the air compressor safety valve is an important part of ensuring the safe operation of the equipment. The following are some basic adjustment methods and precautions:

1.Preparation before adjusting the safety valve: Before adjusting the safety valve, make sure the air compressor is in the shutdown state, check the exhaust system, pipelines and pressure gauge for blockage or damage, and check the tightness of the safety valve to ensure there is no leakage.

2.Adjust the starting pressure: The starting pressure is the pressure at which the safety valve opens and starts to exhaust. According to the work requirements, the starting pressure can be changed by adjusting the spiral spring or other adjustable parts on the safety valve. The specific adjustment method should refer to the manufacturer's instructions.

3.Safety valve closing pressure adjustment: If the safety valve opens too early or too late, the positioning bolts and locking nuts need to be adjusted to ensure that the safety valve can work normally at the specified pressure value.

4.Safety valve maintenance: Check the safety valve regularly for leakage, blockage, spring corrosion and other abnormal phenomena, and pay attention to whether the adjusting screw sleeve and the locking nut of the set screw are loose. If any problems are found, take maintenance measures in time. If necessary, remove the safety valve for comprehensive cleaning, inspection, re-grinding and adjustment before reuse.

5.Inspection and adjustment of safety valve: The safety valve of the air compressor has been adjusted before the whole machine leaves the factory, and the user is not allowed to adjust it privately. If adjustment is necessary, it should be carried out under the guidance of the local labor safety department or the manufacturer's maintenance personnel to avoid adverse consequences.

6.Safety valve type selection: select the type of safety valve according to actual needs, and select its diameter according to the maximum exhaust volume. For example, the model representation method and material requirements of the A28X-16T air compressor safety valve.

7.Installation and protection of safety valves: Safety valves installed outdoors should be protected from rain, fog, dust and other dirt, and anti-freezing measures should be taken when the environment is below zero degrees Celsius.

Following these adjustment and maintenance methods can ensure the normal operation of the air compressor safety valve and prevent equipment damage or accidents caused by excessive pressure.
