Also be equipped with upper and lower O-ring seals between above-mentioned upper and lower valve body and the upper and lower valve rod respectively.
Be equipped with through hole on the above-mentioned butterfly plate, above-mentioned anticorrosive coat makes butterfly plate two outer surfaces be equipped with anticorrosive coat and is connected as a single entity through infiltrating through hole.
Through-hole diameter on the above-mentioned butterfly plate is not of uniform size.
Above-mentioned valve interior surface is equipped with groove, and above-mentioned groove is built-in with elasticity reinforcement pad.
Elasticity reinforcement pad in the above-mentioned groove is a multilayer.
Above-mentioned anticorrosive coat is fluoroplastic.
The present invention compared with prior art has following advantage:
1, the valve interior surface of this alkali-chloride special-purpose fluoroplastic all-liner butterfly valve is equipped with groove, and groove is built-in with elasticity reinforcement pad, and good seal performance is difficult for leaking.
2, be equipped with through hole on the butterfly plate of this alkali-chloride special-purpose fluoroplastic all-liner butterfly valve, anticorrosive coat infiltrates in the through hole, and the anticorrosive coat of butterfly plate two outer surfaces is connected as a single entity, and anti-corrosion layer structure is firm, difficult drop-off, corrosion resistance and good, long service life.
3, the anticorrosive coat of this alkali-chloride special-purpose fluoroplastic all-liner butterfly valve is teflon, and is corrosion-resistant, not yielding, good seal performance, long service life.
4, put tension spring respectively between the upper and lower thrust-bearing of this alkali-chloride special-purpose fluoroplastic all-liner butterfly valve and the upper and lower seal, make seal under the effect of tension spring, good seal performance.
