External anti-corrosion valve pneumatic valve (including variable speed transmission box) inside and outside, the valve type, first, blasting sand blasting, valves, non-toxic epoxy powder electrostatic spraying sought, the thickness of 0.3mm or more. Large electrostatic spraying non-toxic epoxy resin valve difficulty should brush, spray similar to non-toxic epoxy paint. And various parts of the body inside the valve plate calls for a comprehensive anti-corrosion, on the one hand immersed in water will not rust, no electrochemical corrosion between the two metals; two aspects of smooth surface to reduce drag through the water. 6.3 valve body paint anti-corrosion epoxy resin or health requirements, Shandong valves, should be the appropriate authority of the organs test report. Chemical and physical properties should meet the relevant requirements. General Requirements 1.1 pneumatic valve size and type, comply with the piping design documents. 1.2 pneumatic valve models should be specified in accordance with the national standard code requirements. If the enterprise standards, valve manufacturers, models should be specified instructions. 1.3 pneumatic valve job pressure ≥ pipeline working pressure, without affecting the price of the premise, the valve can withstand working pressure should be greater than the actual working pressure pneumatic valve pipe; and on either side of the pneumatic valve closed condition under should be able to withstand 1.1 times the value of the working pressure valve without leakage; lower valve open position, the valve should be able to withstand twice the working pressure valve requirements. 1.4 pneumatic valve manufacturing standards, should explain the basis of the national standard code, if the file should be attached to business enterprise standards, procurement contract. Pneumatic valve packing and shipping on both sides of the valve should be located light blocking plate solid seal. Medium and small-caliber valve should be tied to rope, and transported to suitable container. Large diameter valves are also solid wood frame packaging to avoid collision damage during transport.
