Q: cock common failure initiation comprised prevention method processing out a: tight sealing faces reveal that 1. Cock vice is not closed tightly closed, appearance is made not fine growth quality, color using 1 after seizing and pressure test in accordance with standards. Parking after unloading, repair or change the valve 2. Inappropriate for debugging or debugging device of relaxation and make the tightly closed surface leakage, can see fit and use new debugging and fastening way to eliminate leakage. Often closed to plug valves should be closed and open hole injecting plugging 4. See fit using freezing method, conversion tightly closed method and other methods to repair, change, transform the valve 5. Closely in a closed surface with grinding grain, scratch tightly closed surface or close position, the Industrial Valves is in the whole paper operation should take advantage of dirt on the surface of the media and in the flush valve closely enclosed 6. Oil seal type oil field congestion or lack of oil, seizing and communicate on a regular basis in accordance with the prescribed time and 7. Sealing line of Marine valve drainage hole was chocked up with dirt, miss since the tight tightly closed regular investigation and cleaning performance, medium suitable for sediment containing more than 8. Debugging inappropriate or debug device relaxation destruction: tight pattern compression nut relaxation; Packing type adjustment screw top stopper death; Sealing spring top tight force is too small or lose their effectiveness such as accurate debug plug valves to adjust parts, will be subject to rotating light and tightly closed don't leak 9. Board referred to in the closed position and the actual is not appropriate, initiation leak check regularly, should be referred to in closed position with the board position is exactly the same debugging, repair the board a petition, the board has pointed out the direction and the actual 1 exactly the same stem rotation block. Gland pressure of tight tight, pay attention to the activity at the valve stem, seizing whether the tight fit of diastolic pressure screw or the spiral cover, make its stem rotating flexible 2. Tightly closed surface pressure tight, tight pattern nut screwed tight, sealing the preloaded spring pressure tight compression gland, pay attention to the activity at the valve stem, seizing whether pressure tight 3. Tightly closed surface scratch, regular inspection repair, increased the operating force of oil seal type should be regularly come on parking after unloading, repair or change shall be filed with the oil seal type or opening oil lubricating oil tightly closed surface sees fit and use 'leak valve' to repair or change the valve 4. Lubricating conditions deteriorate packing should be coated with some of its assembly, oil seal type should be regularly quantitative filling 5. Board a disappearing to give an accurate operation, not appropriate is too large to debug the board board suitable gap for the precise location, bonding, welding solid or use the fitter to repair.
