Pneumatic valve opening and closing degree of display panel ① pneumatic valve opening and closing degree of scale line should be cast in the gearbox cover or change the direction of the display after the disc casing, all for the ground wire brush on the phosphor scale to show striking ; ② direct needle plate material is available in the case of better management stainless steel, or steel plate for the painting, valves, do not use aluminum leather production; ③ direct drive needle eye-catching, stable fixation, accurate adjustment when opening and closing, It should rivet locked. External anti-corrosion valve pneumatic valve (including variable speed transmission box) inside and outside, at first, blasting sand blasting, Shandong stainless steel 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, should test reports appropriate authority of the organs. Chemical and physical properties should meet the relevant requirements. Valve shaft packing ① As the pipe network in the pneumatic valve, stainless steel valve manufacturers, usually not open and close frequently, requiring the filling in a few years of inactivity, not aging filler, long-term effects remain sealed; ② fill valve shaft should also bear When frequent opening and closing, good sealing effect; ③ In view of the above requirements, fill valve shaft does not seek to change or 10 years for life without replacement; ④ Packing For replacement under pneumatic valves should be designed to have water pressure conditions change measures.
