Valve repair, there will be life, long or short, but if valve repair properly and timely, then we can extend the human impact on the life of the equipment.
Pneumatic butterfly valve, pneumatic valve, pneumatic valve, pneumatic shutoff valve pneumatic valve products include, but regardless of which valve products, these methods can learn.
, Speaking from the body itself:
1, the valve body (including variable speed transmission box) inside and outside, first of all, blasting sand blasting, and strive to electrostatic spraying powdered non-toxic epoxy resin, the thickness of 0.3mm. The oversize valves electrostatic spraying non-toxic epoxy difficulties, should brush, similar to the non-toxic epoxy paint spraying.
2, the valve internal as well as various parts of the valve plate requires a comprehensive anti-corrosion hand immersed in water will not rust, to produce electrochemical corrosion between the two metals; two aspects of a smooth surface to reduce drag through the water.
3, the valve body corrosion epoxy or paint the hygiene requirements, should be the detection of the appropriate authority to report. The chemical and physical properties should meet the relevant requirements.
Two, pneumatic valve packing and shipping respect to:
1, the valve should be located on both sides of the light blocking plate solid seal.
2, small diameter valves should be tied to rope and transported to suitable container.
3, large diameter valves are also simple wooden frame solid packaging, prevent damage during transport collision damage.
Pneumatic valve factory specifications and other
The pneumatic valve is a device in the factory manual shall be marked with the following data:
Valve specifications; Model; work pressure; manufacturing standards; body material; stem material; sealing material; valve shaft packing material; valve stem bushings materials; internal and external corrosion-resistant materials; operation start direction; revolutions; pressure in the working conditions, the opening and closing torque; manufacturing plant name; factory date; serial number; Weight; the connection flange diameter, number of holes, center hole distance; graphic images indicate the overall length, width and height of the control size; valve flow resistance coefficient; effective opening and closing times; the valve factory testing data and installation, maintenance considerations. Use these data to provide customers with the use of the pneumatic valve products data remind customers products and Note, has played a significant role in the life of pneumatic valve products.
