Description
Technical field
The utility model relates to a kind of valve, is specially the chlor-alkali of controlling and regulate media flow on a kind of chemical industry pipeline and uses extraordinary fluoroplastic all-liner butterfly valve.
Background technique
In the past, the valve of chemical industry for making chlorine and alkali industry was generally the general common valve of sealability.Common valve still is that structure does not possess special-purpose characteristics from material, and it is bad that this valve respectively seals the sealability at position on the one hand, can not stop dielectric leakage well; Under deep-etching, poisonous and hazardous process conditions, often poor sealing performance is prone to leak on the other hand, and housing is prone to perforation, and working life is short, can not satisfy the specific (special) requirements of permanently effective conveying poisonous medium.And chlorine can bring serious consequence to surrounding enviroment and personal safety in case leakage is come out.
Summary of the invention
The purpose of the utility model provides a kind of good airproof performance, and is corrosion-resistant, safe and reliable, and non-maintaining chlor-alkali is used extraordinary fluoroplastic all-liner butterfly valve.
The technological scheme that realizes above-mentioned purpose is: chlor-alkali is used extraordinary fluoroplastic all-liner butterfly valve; Mainly comprise upper valve body, following valve body, butterfly plate, upper valve rod, lower valve rod, Worm gear case assembly and handwheel; Said upper and lower valve interior surface is provided with lining; Between upper and lower valve body and lining, be provided with liner; It is characterized in that: on the step end face of the upper and lower valve rod of butterfly plate, be respectively equipped with a rectangle groove; Be respectively equipped with O type elastic anti-corrosion erosion seal ring in the said rectangle groove, be provided with between upper valve rod and the upper valve body preserving and sealing circle, on polytetrafluoroethylsealed sealed circle and last metallic support circle, be provided with down preserving and sealing circle, polytetrafluoroethylsealed sealed circle and following metallic support circle down down between valve body and the lower valve rod.
Between upper and lower valve body and upper and lower valve rod, be provided with O type elastic anti-corrosion erosion seal ring, preserving and sealing circle, polytetrafluoroethylsealed sealed circle and metallic support circle respectively, improved the sealability and the decay resistance of the utility model, prolonged working life.
On between said upper valve rod and the upper valve body preserving and sealing circle, on the upper end of polytetrafluoroethylsealed sealed circle and last metallic support circle be provided with K type butterfly spring; Below the following preserving and sealing circle between said lower valve rod and the following valve body, following polytetrafluoroethylsealed sealed circle and following metallic support circle, be provided with K type butterfly spring down.Elastic force through K type butterfly spring makes O type elastic anti-corrosion erosion seal ring, preserving and sealing circle, polytetrafluoroethylsealed sealed circle and metallic support circle reach the self-supporting compensation of sealing; Constitute gap-free sealed mechanism; Sealing wear when reducing switch simultaneously; In valve operation and the equipment operation periodic process, need not to change Sealing, reach non-maintaining.
Above-mentioned upper valve body and upper valve rod between be provided with V-type fluoroplastic combined packing circle, V-type fluoroplastic combined packing circle top is provided with the insertion ring pressing plate, said insertion ring pressing plate is fixedly connected with upper valve body through bolt.Guarantee the zero leakage of medium, anti-strong corruption, non-maintaining.
