Pressure reducing valve is a commonly used valve in the industry, which needs to be adjusted according to the specific scene during use. Normally, clockwise rotation can increase the outlet pressure of the pressure reducing valve, and counterclockwise rotation can reduce the outlet pressure. The specific operation is as follows:
1. Before adjusting, confirm whether the medium in the pipeline of the pressure reducing valve is in circulation and whether the medium is in normal working condition. If it is not, please deal with the problem and wait for the media to become normal before adjusting.
2. Slowly rotate the hand wheel of the pressure reducing valve, because the adjustment of the pressure reducing valve is a gradual process and requires repeated debugging. After each adjustment, you can wait a few minutes to ensure that the pressure stabilizes near the set value before performing the next adjustment operation.
3. If you need to increase the pressure, rotate the pressure reducing valve hand wheel clockwise to observe whether the pressure gauge pointer meets the requirements. If the expected pressure value is not reached, continue to adjust the pressure reducing valve hand wheel. On the other hand, if you need to lower the pressure, turn the valve hand wheel counterclockwise, the same need to observe the pressure gauge pointer to determine whether the desired pressure value.
4. If the pressure requirements cannot be met, it is necessary to check whether the components and sealing performance of the pressure reducing valve are normal, and repair or replace them.
2. pressure reducing valve adjustment notes
1. Before adjusting the pressure reducing valve, it is necessary to ensure that the inlet and outlet valves of the system are closed to avoid medium leakage.
2. When adjusting the pressure reducing valve, it needs to be carried out according to the specific requirements, and it is best to carry out repeated debugging to ensure its stability near the set value.
3. During the adjustment process, you need to gently rotate the valve hand wheel, and you cannot twist or twist it hard.
4. After the adjustment is completed, the outlet valve needs to be gradually opened to reduce the impact on the pressure reducing valve and ensure its normal operation.
In short, the correct adjustment of the pressure reducing valve is very important and requires caution when operating. In daily use, it is also necessary to regularly check the working status of the pressure reducing valve, maintain its normal operation, and deal with problems in time.
