API Standard B367 Gr.C-2 Worm Gear Operated Ibhola edadayo Ivalve

Ubuninzi bentsimbi ye-titanium yi-4.51g / cm3, ephakamileyo kune-aluminium kodwa iphantsi kunentsimbi, ubhedu, kunye ne-nickel, kodwa amandla ayo athile aphezulu kunezixhobo zetsimbi. Ukuxhathisa okuqinileyo kwe-titanium alloy valves kungenxa yokuba isiseko sayo, i-titanium, yimathiriyeli yentsimbi esebenzayo kakhulu kunye ne-equilibrium ephantsi kunye nokuthambekela okuphezulu kwe-thermodynamic corrosion phakathi. Enyanisweni, i-titanium izinzile kakhulu kumajelo amaninzi, njenge-oxidizing, ukungathathi hlangothi, kunye nokunciphisa ngokubuthathaka imidiya. Oku kungenxa yokuba i-titanium inobudlelwane obukhulu kunye ne-oxygen. Kwimithombo yomoya okanye i-oksijini ene-oxygen, i-dense, i-adhesion eqinile, kunye nefilimu ye-inert oxide yenziwe phezu kwe-titanium, ikhusela i-titanium substrate kwi-corrosion. Nokuba ngenxa yokunxitywa koomatshini, iya kuziphilisa ngokukhawuleza okanye iphinde izihlaziye. Oku kubonisa ukuba i-titanium yintsimbi enotyekelo oluqinileyo malunga nokudlula. Ifilimu ye-oxide ye-titanium ihlala igcina olu phawu xa ubushushu obuphakathi bungaphantsi kwe-315 ℃.

Ukuze kuphuculwe ukuxhathisa kwe-titanium, itekhnoloji yonyango lomphezulu onje nge-oxidation, i-electroplating, ukutshiza iplasma, i-ion nitriding, ukufakelwa kwe-ion, kunye nonyango lwe-laser ziye zaphuhliswa, eziphucula umphumo wokukhusela wefilimu ye-titanium oxide kunye nokufezekisa ukubola okufunayo. ukuxhathisa. Uthotho lwe-alloys ye-titanium enganyangekiyo kwi-corrosion efana ne-titanium molybdenum, i-titanium palladium, kunye ne-titanium molybdenum nickel ziye zaphuhliswa ukuhlangabezana nemfuno yemathiriyeli yesinyithi ekuvelisweni kwe-asidi yesulfuric, i-hydrochloric acid, izisombululo ze-methylamine, igesi ye-chlorine ebushushu obuphezulu, kunye neekloridi zobushushu obuphezulu. I-Titanium castings yenziwe nge-alloy ye-Ti-32 molybdenum, kunye neendawo apho i-crevice corrosion okanye i-pitting corrosion ivame ukwenzeka, i-Ti-0.3 molybdenum-0.8 i-nickel alloy isetyenziswa, okanye i-Ti-0.2 palladium alloy isetyenziswe ekuhlaleni kwizixhobo ze-titanium, zombini ezi zinto zisetyenziswayo. bazuze amava amnandi kakhulu omsebenzisi.

I-alloy entsha ye-titanium ingasetyenziswa ixesha elide kumaqondo obushushu angama-600 ℃ nangaphezulu. I-Titanium alloys TA7 (Ti-5Al-2.5Sn), i-TC4 (Ti-6Al-4V), kunye ne-Ti-2.5Zr-1.5Mo imele i-ultra-low-low titanium alloys, kwaye amandla abo ayanda ngokuhla kweqondo lokushisa, kodwa iplastiki yabo itshintsha kancinci. Ukugcina i-ductility elungileyo kunye nokuqina kumaqondo obushushu asezantsi kakhulu -196-253 ℃ kuthintela ukuqhwalela okubandayo kwezixhobo zetsimbi, kuyenza ibe yinto efanelekileyo kwizikhongozeli ezinobushushu obuphantsi, iitanki zokugcina, kunye nezinye izixhobo.

- Ubungakanani ukusuka kwi-2 "ukuya kwi-8" (i-DN50mm ukuya kwi-DN200mm).
- Imilinganiselo yoxinzelelo ukusuka kwiKlasi ye-150LB ukuya kwi-600LB (PN10 ukuya kwi-PN100).
- RF, RTJ okanye BW ekupheleni.
-I-PTFE, inayiloni, njl.
- Imowudi yokuqhuba ingaba yincwadana, yombane, i-pneumatic, okanye ixhotyiswe ngeqonga le-ISO.
- Cast titanium imathiriyeli B367 Gr. C-2, B367 Gr. C-3, B367 Gr. C-5, B367 Gr. C-6, B367 Gr. C-7, njl.

I-lever eyandisiweyo yokusebenza lula kwaye iyafumaneka kunye negiya, ii-motor actuators, i-pneumatic okanye i-hydraulic actuators kwiinkonzo ezinzima ngakumbi.

Yahlula okanye i-3-piece, umzimba wokwahlula kunye nebhonethi ye-12 "&small.disassembles ngokulula ukulungisa amacandelo.

I-Std yokupakisha i-v-teflon yokupakisha emininzi, idibaniswe nokulayisha okuphilayo, igcina ukunyanzeliswa kokupakisha phantsi komjikelo ophezulu kunye nezicelo zenkonzo enzima. Ukupakishwa kwegraphite kusetyenziselwa imeko yobushushu obuphezulu.

Uyilo lwesiqu sobungqina obuvuthuzayo luyilo lwegxalaba olukhuselekileyo olukhusela ukusilela phantsi koxinzelelo olugqithisileyo.

Uyilo lweAnti statics. Uqhagamshelwano lwesinyithi luhlala lunikezelwa phakathi kwebhola kunye nesiqu / umzimba ukukhupha ukwakheka kwe-statics ngexesha lenkonzo.

Ukhuseleko lomlilo lwenzelwe i-API607 okanye i-BS 6755 ukunika ukufaneleka komsebenzi wabo kwimeko yomlilo. Intsimbi yesibini ukuya kwitywina lentsimbi lisebenza njengegcisa ukuba itywina lokuqala litshatyalalisiwe ngomlilo. Iivalvu eziyalelwe ukuthotyelwa kwe-API 607 ​​ziya kunikwa ukupakishwa kwegraphite kunye neegaskets.
