I-API Standard B367 Gr.C-2 Worm Gear Operated Floating Ball Valve

Ukuminyana kwensimbi ye-titanium ngu-4.51g/cm3, ephakeme kune-aluminium kodwa ephansi kunensimbi, ithusi, ne-nickel, kodwa amandla ayo athile aphakeme kunalawo ezinto zensimbi. Ukumelana nokugqwala okuqinile kwamavalvu e-titanium alloy kungenxa yokuthi isisekelo sayo, i-titanium, iyinsimbi esebenza kakhulu enamandla aphansi okulingana kanye nokuthambekela okuphezulu kokugqwala kwe-thermodynamic phakathi nendawo. Eqinisweni, i-titanium izinzile kakhulu emithonjeni eminingi yezindaba, efana ne-oxidizing, neutral, kanye nemidiya yokunciphisa kancane. Lokhu kungenxa yokuthi i-titanium inokuhlobana okukhulu nomoya-mpilo. Emoyeni noma emithonjeni yezindaba equkethe umoya-mpilo, ifilimu eqinile, enamathelayo, ne-inert oxide yakheka ebusweni be-titanium, ivikela i-titanium substrate ekugqwaleni. Ngisho nangenxa yokugqoka komshini, izoziphilisa ngokushesha noma izikhiqize kabusha. Lokhu kubonisa ukuthi i-titanium iyinsimbi enokuthambekela okunamandla kokudlula. Ifilimu ye-oxide ye-titanium ihlale igcina lesi sici lapho izinga lokushisa eliphakathi nendawo lingaphansi kuka-315 ℃.

Ukuze kuthuthukiswe ukumelana nokugqwala kwe-titanium, kuthuthukiswe ubuchwepheshe bokwelapha obungaphezulu obufana ne-oxidation, i-electroplating, ukufafaza i-plasma, i-ion nitriding, ukufakwa kwe-ion, nokwelashwa nge-laser, kuye kwasungulwa, okuthuthukisa umphumela wokuvikela wefilimu ye-titanium oxide futhi kufinyelele ukugqwala okufunayo. ukumelana. Kuthuthukiswe uchungechunge lwengxube ye-titanium engagqwali njenge-titanium molybdenum, i-titanium palladium, ne-titanium molybdenum nickel ukuze kuhlangatshezwane nesidingo sezinto zensimbi lapho kukhiqizwa i-sulfuric acid, i-hydrochloric acid, izixazululo ze-methylamine, igesi ye-chlorine eshisa kakhulu, kanye nama-chloride aphezulu okushisa. Ukufakwa kwe-Titanium kwenziwa nge-Ti-32 molybdenum alloy, nasezindaweni lapho ukugqwala kwe-crevice noma ukugqwala kwemigodi kuvame ukuvela, kusetshenziswa i-Ti-0.3 molybdenum-0.8 nickel alloy, noma i-Ti-0.2 palladium alloy isetshenziswa endaweni emishinini ye-titanium, zombili lezi zinto ezisetshenziswayo. bathole ulwazi oluhle kakhulu lomsebenzisi.

Ingxubevange entsha ye-titanium ingasetshenziswa isikhathi eside emazingeni okushisa angama-600 ℃ noma ngaphezulu. Ama-alloys e-Titanium TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), kanye ne-Ti-2.5Zr-1.5Mo amele izinga lokushisa eliphansi kakhulu le-titanium alloys, futhi amandla awo akhuphuka ngokuncipha kwezinga lokushisa, kodwa ipulasitiki yabo ishintsha kancane. Ukugcina i-ductility enhle nokuqina emazingeni okushisa aphansi kakhulu -196-253 ℃ kuvimbela ukubola okubandayo kwezinto zensimbi, kuyenze ibe into efanelekile yeziqukathi ezinezinga lokushisa eliphansi, amathangi okugcina, nezinye izinsiza.

- Usayizi kusuka ku-2 "kuya ku-8" ( DN50mm kuya ku-DN200mm).
- Izilinganiso zokucindezela ukusuka ku-Class 150LB kuya ku-600LB (PN10 kuya ku-PN100).
- RF, RTJ noma BW ekupheleni.
- PTFE, Inayiloni, njll.
- Imodi yokushayela ingaba yezandla, kagesi, i-pneumatic, noma ifakwe isiteji se-ISO.
- Cast titanium impahla B367 Gr. C-2, B367 Gr. C-3, B367 Gr. C-5, B367 Gr. C-6, B367 Gr. C-7, njll.

I-lever enwetshiwe ukuze isebenze kalula futhi iyatholakala namagiya, ama-motor actuators, ama-pneumatic noma ama-hydraulic actuators ngezinsizakalo ezinzima kakhulu.

Hlukanisa noma izingcezu ezi-3,hlukanisa umzimba nebhonethi ngo-12" &small.iqaqa kalula ukuze ilungise izingxenye.

I-Std ipakisha ukupakisha okuningi kwe-v-teflon, kuhlanganiswe nokulayisha bukhoma, igcina ukucindezelwa kokupakisha ngaphansi komjikelezo ophezulu kanye nezinhlelo zokusebenza zesevisi ezinzima. Ukupakisha kwe-graphite kusetshenziselwa isimo sokushisa okuphezulu.

Idizayini ye-stem yobufakazi obuphuphumayo iyidizayini yehlombe yesiqu ephephile evikela ukwehluleka ngaphansi kwengcindezi eyeqile.

Idizayini ye-Anti statics. Ukuthintana kwensimbi kuhlala kunikezwa phakathi kwebhola nesiqu /umzimba ukuze kukhishwe ukwakheka kwe-statics ngesikhathi sesevisi.

Isisefo somlilo esidizayinelwe ku-API607 noma i-BS 6755 ukunikeza ukufaneleka kokusebenza kwazo uma kwenzeka kuba nomlilo. Isigxivizo sesibili sensimbi kuya kwesensimbi sisebenza njengesipele uma uphawu lokuqala lucekelwa phansi ngomlilo. Amavavu a-odelwe ukuthobela i-API 607 ​​azohlinzekwa ngokupakishwa kwe-graphite nama-gaskets.
