ZJY46H piston type pressure reducing valve products are mainly fault and eliminate method

fault phenomenon may cause process methods P2 pressure cannot be adjusted to the rated pressure spring pressure rating and rating does not change the main valve spring main valve type O rubber sealing ring wear, damage on the replacement of the main Industrial Valves, the O rubber sealing ring when the water mud, dirt is large, the control valve filter recoil drainage clogging timing for operation, washing to remove dirt it replaced jet pump control valve failure were choked up with silt, sundry remove feedback system, jet pump pressure P1, P2, close to the cleaning, namely not decompression Industrial Valves main valve sealing rubber parts wear and damage to replace the main valve type O rubber seal valve disc jam, loose replaced main valve cover hole water piston seal rubber parts wear and tear, damage to replace O rubber sealing ring piston collision, damage replace piston valve top water seepage control valve piston or O type rubber sealing ring damage replaced P2 values are not stable, Low voltage fluctuations) Main valve throttle cone loose assembly will throttle assembly fastening cone piston sliding surface such as mud sediment piston sliding surface cleaning, if necessary, change the O rubber sealing ring and piston ring valve throttle loose cone resistance, replaced the P2 value in the process of running down to the lock nut safe lock the opening of throttle cones in downtime or import under the condition of low pressure value to adjust the lock nut clearance impurities of congestion control valve for recoil drainage operation
