Abstract

The invention discloses an anticorrosive drainage valve. The outer surface of an drainage valve is coated with an anticorrosive layer; the anticorrosive layer is formed by coating anticorrosive paint; the anticorrosive paint is prepared from a component A and a component B, wherein the component A is prepared from the following components: polyphenylene oxide resin powder, methylphenyl silicone resin, modified waterborne polyurethane emulsion, a coupling agent, a curing agent, a curing agent accelerant DMP-30, pigment and filler and a dispersant; the component B is prepared from the following components: nano SiC powder, styrene-acrylic emulsion, a flatting agent, a thickener, an emulsifier and a de-foaming agent; the anticorrosive drainage valve provided by the invention has the advantages that the valve has a good anticorrosive effect and can be used in environment with relatively poor water quality; the service life is long and the cost is reduced.

Description

technical field [0001] The invention relates to a valve, in particular to an anti-corrosion drain valve. Background technique [0002] At present, valves are often used in petroleum, chemical, metallurgy and other industrial fields. The basic function of steam traps is to discharge the condensed water, air and carbon dioxide gas in the steam system as soon as possible; at the same time, it can automatically prevent the leakage of steam to the greatest extent. There are many kinds of steam traps, each with different performance. When choosing a steam trap, you should first choose its characteristics to meet the best operation of the steam heating equipment, and then consider other objective conditions, so that the choice of the steam trap you need is correct and effective. However, the preparation function of the current valve The main material is a metal material, but the metal material is easy to wear and corrode, which increases the cost.
