VALVES COMMON FAULTS AND TREATMENT
Q1. Leakage of valve body:
Reason: 1.The valve body has sand holes or cracks
        2.The valve body cracks when rewelding.
    Processing: 1.Polish the suspected crack with 4% nitric acid soluation. If there is any crack,it can be shown.
               2.Dig and repair cracks.
Q2.Damaged stem and its mating thread,broken stem head and bent stem:
    Reason: 1.Improper operation,excessive fore of the switch,malfunction of the limit device and no action of overtorque protection.
             2.The thread is too loose or too tight
             3.Excessive operation times and long service life
    Processing: 1.Improve the operation and do not use too much force; Check the limit device and check the torque protectiong device.
                2.Suitable material selection and assembly tolerance meet the requirements
                3.Replace spare parts.
Q3.Valve cover joint surface leakage
    Reason:1 Insufficient bolt tension or deviation
            2 The gasket does not meet the requirements or the gasket is damaged;
            3 There are defects in t he binging surface.
    Processing:1.Tighten the bolts or make the flange clearance of the cover consistent
               2.Replace the gasket
               3.Disassemble the sealing cover of the door cover
Q4.Valve leakage
    Reason;1.The closure is not strict.
            2.Bond surface damage.
            3.The clearance between the valve core and stem is too large, causing the valve core to sag or poor contact.
            4.Poor sealing materials or stiff valve core.
    Processing:1.Improve operation, restart or close.
               2.The valve disintegrates and the sealing surface of the valve core and seat is re-ground
         3.Adjust the clearance between the valve core and stem or replace the valve dics.
         4.The valve disintegrates to eliminate the stickiness.
         5.Replace of stack the sealing rings,
Q5.The valve core is separated from the stem, causing the switch failure.
    Reason:1.Improper repair.
            2.The joint between the valve core and stem is corroded.
            3.Excessive force of the switch causes damage to the joint between the valve core and stem
            4.The core check gasket is loosened and the connecting part is worn
    Processing;1.Pay attention to inspection during maintenance.
               2.Replace the corrosion resistant door stem.
               3.The operation is not to force the switch or to continue to open the valve after full opening.
               4.Check and replace damaged spare parts.
Q6.There are cracks in the valve core and seat.
    Reason; 1.Poor quality of bonding surface surfacing.
            2.Large temperature difference between two sides of valve.
    Processing:Repair welding of cracks,heat treatment,polishing and grinding as required.
Q7. The valve stem fails to lift or switch properly.
    Reason:1.It is closed too tightly in the cold state; it will swell to death after being heated ;or it will be too tight after being fully opened.
            2.The packing is pressed too tightly.
            3.The stem clearance is too small and dies of distension,
            4.The valve stem is too tight with the screw base, or the screw buckle is damaged
            5.Packing gland pressure deviation.
            6.Bent door bar.
            7.The medium temperature is too high,the lubricatrion is good, and the valves stem is seriously corroded.
    Processing:1.After heating the valve body, slowly try to open or fully open and close slightly when it is tight.
               2.Slightly loosen the packing gland and try to open it.
               3.Appropriately increase stem clearance.
               4.Replace the stem and thread holder.
               5.Readjust packing gland bolts.
               6.Straightening the door lever or replacing it.
               7.The door bar is lubricated with pure graphite powder.
Q8.Packing leakage.
   The reason:1.Wrong stuffing materials.
              2.The pacing gland is not compacted or deviced.
              3.The filling method is wrong.
              4.Valve stem surface damage
  Processing:1.Select the correct packing.
             2.Check and adjust packing gland to prevent deviation.
             3.Add the stuffing in the correct way.
             4.Repair or replace the stem
