Pressure regulator valve installation and troubleshooting

First, the installation and commissioning 1. Relief valve before installation, the nameplate certificate is consistent with the required valve, the appearance of serious damage. Rinse the pipe thoroughly and rinse the pressure relief valve. If the pressure relief valve is stored for too long, fully clean the internal pressure relief valve. 2. If the valve itself does not have a pressure gauge, pipe pressure gauges should be installed behind the valve front valve. 3. In order not to affect the use of decompression effect, taking into account the ease of installation and maintenance, the general should be installed on the horizontal pressure relief valve, bellows-type valve for the flip. 4. Before installation must pay attention to the direction of the arrow on the valve body, the arrow points to the direction of medium flow, can not be installed anti-If the medium contains impurities, may block the valve hole, to be installed before the pressure relief valve inlet filter about 1 meter , The filter mesh at 20 mesh above the best. 5. In order to prevent overpressure valve pressure over accident, relief valve outlet port should be installed 4 meters safety relief valve. Second, the common fault and maintenance methods 1 medium can not pass or throughput is very small. This situation are generally blocked the channel, clear the channel dirt can be. Straight through a. Piston stuck. Method: Remove dirt between cylinder liner and piston. b. The main pilot valve stem stuck in the pilot hole. Method: The main pilot valve stem yarn with a small diameter mill. c. main, pilot valve sealing surface dirt stuck. Method: Remove dirt. d. Diaphragm damage. Method: replace the new film. 3. Pressure can not be adjusted. a. Cylinder liner and piston clearance is too large. Method: Replace the liner or piston. b. adjust the spring strain or adjust the spring exceeds the upper and lower limits. Method: Change new or suitable spring. 4. Pressure valve instability. a. Inlet pressure fluctuation range is too large. Method: Try to keep the inlet pressure fluctuating in a small area. b. The difference between the required flow rate and the actual flow rate is too large. Method: Recalculate the flow, choose the appropriate caliber.
