Description
Technical field
The utility model relates to a kind of wear-resistant valve, and especially a kind of mixing internal sealing type slag is starched wear-resistant lock dish cutter valve.
Background technique
Wear-resistant valve is applicable to that industries conveyings such as electric power, metal mine, coal contain the usefulness of the corrosion resistance slurry of solid particle.In China, be used to carry the wearable valve research of corrosivity granule medium to start late, thereby no matter all exist bigger defective from aspects such as working life, sealability, Flow-rate adjustment, do not have very good slurries valve at present.What the slurries valve that present most industry is used adopted mostly is Clean water valve or the mentality of designing of continuing to use the Clean water valve structure characteristic; Adopt more wear-resistant material to process; Though increase than Clean water valve working life; But the defective of bringing in the time of can not avoiding carrying slurries that is difficult to overcome, its using effect and life-span are difficult to reach perfect condition.We know, carry the sealing pair wearing and tearing of the used valve of clear water very slight, also do not exist because of particle and dirt deposition, fouling cause to stop up and cause opening and closing failure phenomenon.The early damage that yet when being used to carry the corrosivity slurries, situation is just made a world of difference, and weares and teares, wash away, eddy current, obstruction, fouling all can cause valve, the life-span falls sharply.The precision and the degree of finish of sealing pair because valve seal places one's entire reliance upon, thereby sealing pair has wearing and tearing, scuffing and fouling will lose sealability slightly, leaks in forming.Be difficult to guarantee sealability and working life so continue to use the slurries valve that the Clean water valve mentality of designing designed.Situation during in particular for Flow-rate adjustment, sealing surface will be destroyed by being flushed in the very short time of aggressive medium directly, and working life is less than three months sometimes.Yet, because the frequent change of customer equipment load is reasonable for guaranteeing the pump operation operating mode, reaching purposes such as economical operation, saving water source, Flow-rate adjustment can often be used.
Summary of the invention
The technical problem that the utility model will solve provides a kind of favorable sealing property, can improve the mixing internal sealing type slag in working life starches wear-resistant lock dish cutter valve;
And it is wear-resistant to folder cutter valve with mixing internal sealing type slag slurry further to provide a kind of mixing internal sealing type slag to starch wear-resistant flange cutter valve on this basis.
For solving the problems of the technologies described above, this mixing internal sealing type slag is starched the technological scheme that wear-resistant lock dish cutter valve taked and is: it comprises butterfly modulating valve and the gate valve that is combined into one, and said butterfly modulating valve is positioned at the passage of gate valve outlet end; Said gate valve comprises inlet valve casing, outlet valve casing and the valve plate of butt joint, chamber of said inlet valve casing and the middle formation of outlet valve casing, and its key technology is: in said chamber, be provided with hybrid Sealing and wear-resisting semicircle lining ring; Said wear-resisting semicircle lining ring is arranged at the semicircle bottom, bottom of chamber; Said hybrid Sealing is made up of three sections sealing components that set gradually from top to bottom;
Said first section sealing component is the abrasive rubber lining at chamber upper semi-circle place; Said abrasive rubber lining is located at the top of wear-resisting semicircle lining ring; It comprises two-part that left and right sides shape is identical, and its structure is on rectangular plate, to offer and be installed in the inlet valve casing and export the inlet anti-wearing liner in the valve casing and export the breach semicircle that the anti-wearing liner shape is complementary; Said second section sealing component is the inner sealing liner plate, and said inner sealing liner plate is to be located at being used to around the valve plate to eliminate valve plate and each side-play side plate, and the shape of side plate and the shape of valve plate adapt; Said the 3rd section sealing component is to be used to prevent the outwards packing seal structure of leakage of liquid.
Above-mentioned wear-resisting semicircle lining ring is that material is the seal ring of wear resistant rubber or high-chromium material.
Above-mentioned abrasive rubber lining is that material is the seal ring of wear resistant rubber.
Above-mentioned inner sealing liner plate is that material is the liner plate of high molecular polymer or nylon.
Above-mentioned mixing internal sealing type slag is starched wear-resistant lock dish cutter valve simply improve the valve body that distortion just can become other types; If such as above-mentioned dish-like modulating valve is removed, then become and mix the wear-resistant flange cutter of internal sealing type valve, all the other structures are identical.If the short tube in ingress and outlet port is removed, it is wear-resistant to folder cutter valve then to become the mixing internal sealing type, and both all the other structures are identical.
Adopt the beneficial effect that technique scheme produced to be: 1) the utility model is to close and regulate the dual-purpose combination brake switch and proporting of flow; Its characteristics according to conveyance fluid are provided with hybrid sealing configuration and wear-resisting semicircle lining ring; Wherein wear-resisting semicircle lining ring can protect the valve casing bottom not washed away, and has improved the working life of inlet valve casing and outlet valve casing;
2) first section sealing component is the abrasive rubber lining, can improve valve plate and open back two angular position erosion resistibilities, and second section sealing component is the inner sealing liner plate; It is the nylon side plate; Control gap is very little between each side plate and the valve plate, can effectively reduce the leakage pressure at slurries phase filling place, so the filler place needn't use very big pretightening force just can realize effective sealing; Therefore valve plate is opened just very light; Guidance quality is very reliable, and the 3rd section sealing component is packing seal structure, to avoid the outside seepage of liquid.
3) the utility model is the isotropic disk valve, adopts the valve of the equal bore of this hybrid sealing configuration can improve a pressure rating than the simple packing seal valve bearing capacity that adopts.
