Abstract
The invention discloses a whole lined stop valve with fluorin plastic specially used in chlorine alkali, comprising a valve body, a valve clack, a valve cap, a gland bush, a valve stem and a hand wheel. An annular sealing ring is arranged between the valve cap and the valve stem. The differences are that: a plurality of grooves are respectively arranged on internal surfaces of the valve body and the valve cap, on external surfaces of the valve clack and the valve stem locating below of the gland bush; anticorrosive coatings are respectively arranged on internal surfaces of the valve body and the valve cap, on external surfaces of the valve clack and the valve stem locating below of the gland bush; and the anticorrosive coatings are infiltrated into the grooves and whole bodies are respectively formed on a same surface. The whole lined stop valve with fluorin plastic specially used in chlorine alkali had the advantages of good sealing performance, corrosion resistance, safety and reliability and long service life.
Description
Technical field
The present invention relates to a kind of valve, relate 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 object of the present invention is to provide a kind of sealing configuration novelty, good seal performance, corrosion-resistant, safe and reliable, the fluoroplastics whole lining stop valve special for alkali-chloride of long service life.
The technological scheme that the present invention solves its 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 present invention 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.
2, be equipped with through hole on the flap of this fluoroplastics whole lining stop valve special for alkali-chloride, anticorrosive coat infiltrates in the through hole, and the anticorrosive coat of flap upper and lower surface is connected as a single entity, and anti-corrosion layer structure is firm, is difficult for dislocation, good seal performance.
3, the anticorrosive coat of this fluoroplastics whole lining stop valve special for alkali-chloride is teflon, and is corrosion-resistant, not yielding, good seal performance, long service life.
