Nanu la reng importanting bage a dapat ikonsidera nung mamili kang ustu seal material para keng metung a aplikasyun?
Masanting a presyu ampo kwalipikadung kule
Availability da reng seal
Deng eganaganang makaimpluwensya keng sealing system: alimbawa ing temperature range, fluid ampo pressure
Deti ngan importanti lang bage a dapat ikonsidera keng kekang sealing system. nung balu la ngan deng sangkan, maging mayan ing mamili keng ustung materyales.
Pero ing kailangan, ing materyal dapat matibe ya. Kaya ing mumunang bage a dapat ikonsidera yapin ing technical performance. magumpisa tamu keng performance factor.
Ing bie ning sistema ampo ing gastus ila reng importanting sangkan (TIanjin Tanggu Water-Seal Valve Co.,ltd) para isipan. Deng sablang bage makaapektu la keng kekang aplikasyun. importanti ing isipan ing design factors agpang keng aplikasyun. Kayabe la kareti deng materyales a ginamit, hugis ning hardware ampo prosesu ning pamaglalang. Atin mu namang environmental factors a dapat ikonsidera kayabe na ing: pressure, temperatura, oras, assembly ampo media.
elastomer
Deng elastomer popular la keng karelang masanting a elasticity. Ala nang aliwang materyales na atin parehung level ning elasticity.
Deng aliwang materyales antimo reng polyurethanes ampo reng thermoplastics mas lalaban la keng pressure kesa kareng elastomers.
Deng materyales a goma malyari lang gamitan kareng miyayaliwang aplikasyun.
Deng importanting mekanikal a katangian kayabe la
elasticity
katigasan
sikanan ning tensile
Deng aliwang importanting bage ilapin deng
•Compression set
•lalaban keng pali
•mababa ing temperatura
•chemical compatibility
•Anti-aging
•lalaban keng pangagasgas
Ing pekamaulaga nang bage yapin ing elasticity ning materyales a goma. abalu tamu pa tungkul kanini.
Ing elasticity ing bunga ning vulcanization. Deng elastomeric a materyales, antimo ing vulcanized rubber, mibalik la keng karelang sadyang porma nung masira la.
Deng e elastic a materyales, antimo ing e vulcanized a goma, e la mibalik king karelang sadyang kabilian nung masira la. Vulcanization (antimodouble flange butterfly valve) ing prosesu ning pamagbayu keng goma para maging elastomeric a materyales.
Ing pamili kareng elastomers keraklan makabasi ya keng:
•range ning temperatura ning obra
•Laban kareng likidu ampo gas
•Laban keng panaun, ozone ampo UV rays

Anam a bage na dapat ikonsidera nung mamili kang valve sealing surface materials
Ing sealing surface ya ing peka-kritikal a working surface ningbalbula, ing kalidad ning sealing surface direktang makaapektu keng bie ning serbisyu ningbalbula, at ing materyales ning sealing surface metung yang importanting sangkan para makasiguradung ing kalidad ning sealing surface. Uli na niti, dapat lang ikonsidera deng makatuking bage nung mamili kang materyales a pang-seal ning balbula:
①Laban keng kaagnasan. Ing "corrosion" yapin ing prosesu nung nukarin ing babo ning sealing surface masira ya keng aksyon ning medium. nung ing babo ning sealing surface mesira ya, ing pamag-sealing performance e malyaring garantisadu, inya ing materyales ning sealing surface dapat e ya corrosion-resistant. Ing corrosion resistance ning metung a materyal makayagpang ya keng komposisyun ning materyal ampo ing kayang chemical stability.
②Anti-abrasion. Ing "scratch" mangabaldugan yang pangasira a sangkan ning friction ning materyal kabang maglakbe ya ing sealing surface. Ing makanining pangasira siguradung maging sangkan ning pangasira ning sealing surface. Uli na niti, ing sealing surface material dapat atin yang masanting a anti-scratch properties, lalu na para kareng gate valves. Ing panga-scratch ning metung a materyal maralas yang makabasi keng kilub ning materyal.
③Erosion resistance. Ing "erosion" yapin ing prosesu ning pangasira ning sealing surface nung ing medium mamagus ya keng sealing surface keng matas a bilis. Ing anti kaniting pangasira mas malino ya kareng throttle valves ampo safety valves a gagamitan da keng matas a temperatura ampo matas a pressure a steam media, ampo atin yang maragul a epektu keng pangasira ning pamag-seal. Uli na niti, ing pamaglaban king pangasira metung ya kareng maulagang kailangan para king pamagseal kareng materyales king babo.
④Dapat atin yang metung a katatagan, at ing katatagan bababa yang maragul keng lalam ning metung a temperatura ning obra.
⑤Ing linear expansion coefficient ning sealing surface ampo ing body material dapat parehu la, na mas importanti para keng istruktura ning sealing ring, para aiwasan ing sobrang stress ampo loosening keng matas a temperatura.
⑥nung gamitan ya keng matas a temperatura, kailangan atin yang sapat a anti-oxidation, thermal fatigue resistance ampo thermal cycle issues.
keng kasalukuyan a sitwasyun, masakit ing manintun sealing surface material na makatupad kareng requirements. Malyari tamung magfocus keng pamagtupad kareng requirements da reng mapilan a aspetu agpang kareng miyayaliwang uri ning balbula ampo gamit. Alimbawa, deng balbula a gagamitan da keng high-speed media dapat lang mamye espesyal a pansin keng erosion resistance requirements ning sealing surface; at nung ing medium atin yang solidung impurities, ing sealing surface material a mas matas a hardness ing dapat pilinan.
