| 1. The pressure reducing valve should be stored in a dry room. Both ends of the passage must be blocked by blind plates. It is not allowed to be stacked and stored. 2 The long-term storage pressure reducing valve should be inspected regularly to clean the dirt, and should be cleaned on all moving parts and processing surfaces. coated with rust inhibitors to prevent rusting. malfunction and causes elimination Symptom relief valve without removing method under reduced pressure or under reduced pressure through a main valve and a failure to pay the valve seal surface or the second main valve dirt or pay the valve seal Face damage 3 main, pay valve spring fatigue or break 4 feedback channel 3 hole is blocked 5 diaphragm fatigue or damage 6 piston cylinder wear or corrosion 7 piston ring groove and piston ring stuck 8 valve body cavity filled with condensate 1. Remove the dirt and dry it. Sealed by grinding repair or replacement 3. Replace the new spring 4. Clear the dirt in the channel. Replace the diaphragm 6. Machining correction or replacement of the piston ring 7. Remove the piston cleaning. Loosen the screw plug to discharge the condensate and not pass the steam. During the cleaning process, the valve cover is misplaced. 2 The gasket is displaced to block the inlet and outlet hole 3. The valve hole is blocked. Remove the valve cover and fix it. Align the gasket hole with the inlet and outlet holes 3. Remove the bonnet to remove dirt from the channel. |
