Abstract
The utility model discloses a fluoroplastic full-lining cut-off valve which is dedicated to the alkali-chloride, comprising a valve body, a valve flap, a valve cover, a pressing cover, a valve pole, a hand wheel, and a ring-shaped sealing ring which is arranged between the valve cover and the valve pole. The different point is that the inner surface of the valve body, the inner surface of the valve cover, the outer surface of the valve flap and the outer surface of the valve pole under the pressing cover of the are evenly provided with grooves, the inner surface of the valve body, the inner surface of the valve cover, the outer surface of the valve flap, and the outer surface of the valve pole under the pressing cover are evenly provided with antisepsis layers which permeate into the grooves and form an integral body on the same surface respectively. The cut-off valve has the advantages of excellent sealing performance, corrosion resistance, safety and reliability, and long life span.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to the fluoroplastics whole lining stop valve special for alkali-chloride of controlling and regulate media flow on a kind of chemical industry pipeline.
Background technique
At present, the valve that China's chemical industry is used for the control of deep-etching flowing medium such as chlor-alkali mostly is the plain cast iron valve of no liner or part liner greatly, and it is mobile to be used on the chlor-alkali pipeline controlling liquid, and corrosivity is big, liner easily comes off, fragile, produce and leak, even security incident takes place, valve is short working life, change frequently, influence is produced, and causes economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing configuration novelty, and good seal performance is corrosion-resistant, safe and reliable, the fluoroplastics whole lining stop valve special for alkali-chloride of long service life.
The technical scheme in the invention for solving the technical problem is: a kind of fluoroplastics whole lining stop valve special for alkali-chloride, it comprises valve body, flap, valve gap, gland, valve rod, handwheel, be equipped with O-ring seal between above-mentioned valve gap and the valve rod, difference is, above-mentioned valve interior surface, above-mentioned valve gap internal surface, the outer surface of above-mentioned flap, above-mentioned valve rod is positioned at the following outer surface of gland and all is equipped with groove, above-mentioned valve interior surface, above-mentioned valve gap internal surface, the outer surface of above-mentioned flap, above-mentioned valve rod is positioned at the following outer surface of gland and all is equipped with anticorrosive coat, above-mentioned anticorrosive coat infiltrates in the above-mentioned groove, forms whole on same surface respectively.
The width of rebate of above-mentioned groove is not more than the bottom land width.
Be equipped with through hole on the above-mentioned flap, above-mentioned anticorrosive coat infiltrates in the through hole, and the anticorrosive coat of flap upper and lower surface is connected as a single entity.
Above-mentioned anticorrosive coat is fluoroplastic.
The utility model compared with prior art has following advantage:
1, the valve interior surface of this fluoroplastics whole lining stop valve special for alkali-chloride, valve gap internal surface, the outer surface of flap, valve rod are positioned at the following outer surface of gland and all are equipped with groove, groove is built-in with anticorrosive coat, and the width of rebate of groove is not more than the bottom land width, the anticorrosive coat fixation, come off, corrosion resistance and good, long service life.
