The pressure regulating valve is also a very important accessory setting of the laser cutting machine, so once the pressure regulating valve has problems, it will also meet the normal use of the cutting machine equipment. Therefore, it is necessary to maintain the pressure regulating valve regularly. The maintenance of equipment pressure regulating valve will be discussed in the following sub series.
1. Installation precautions
Before installing the pressure regulating valve on the laser cutting machine, remember to blow out the dust, oil and other fine particles in the pipeline, and ensure that the fragments of the sealing material will not be mixed into it;
2. Precautions in use
When the high humidity in the air causes condensate, the condensate will stay in the valve, which is likely to lead to the poor state of the pressure relief valve. Therefore, the handle should be installed below to facilitate timely control. Do not install the inlet and outlet in the opposite direction, otherwise the pressure reducing valve will leak for a long time and lose the pressure regulating function; The two pressure reducing valves carry out high-pressure and low-pressure alternate air inlet circuits respectively. Please use a check valve to prevent backflow.
If there is condensate, oil, dust, etc. in the pressure pipe at the inlet side, it will lead to regular drainage or blockage of the throttle valve, thus affecting the effect of the pressure regulating valve. Therefore, a filter should be installed in front of the pressure reducing valve to prevent dust, oil, etc. At the same time, it should be used within a certain temperature range. In addition, avoid direct sunlight and damage; Leave appropriate space around pressure regulation operation and maintenance; After the pressure regulating operation is completed, the regulating button of the pressure reducing valve should be locked.
