Problems solved by technology

[0002] The metal valve is an important part of the high-temperature steam tank, and the metal valve is easily damaged. The damage of the parts will easily lead to the scrapping of the whole equipment, which greatly increases the scrapping rate and poses a great threat to environmental pollution. In order to improve this situation and reduce the scrap rate, the present invention proposes a high-temperature-resistant treatment process for nano-surface high-temperature-resistant metal valves

Abstract

The invention discloses a high-temperature resistant treatment process for a nano surface high-temperature resistant metal valve. Coating of a nano high-temperature resistant layer comprises the following specific operation steps that (1) the valve is cleaned through purified water at the temperature of 60-70 DEG C, blow-dried at the temperature of 80-90 DEG C and then naturally cooled to the indoor temperature, and the rubber surface of the dried valve is cleaned through a fatty hydrocarbon type solvent for 1-3 times, flushed through purified water at the temperature of 45 DEG C again and finally blow-dried by a fan for standby application; (2) nano high-temperature resistant coating is prepared; (3) the valve treated in the step (1) is fed into a heating furnace to be preheated to 250-350 DEG C and then enters a spraying device, small sand grains are sprayed to the surface of the valve through a spraying gun, the thickness is 0.02-0.04 mm, and the spraying process is repeated till the thickness of film coating is 0.04-0.08 mm; and (4) the valve sprayed with the abrasion resistant coating is cooled, checked and put in storage. Not only is the working efficiency improved, but alsoenvironment pollution is reduced, the production cost is reduced, and the steps are simple and convenient to operate.
