B367 Gr.C-2 Worm Gear Operated Trunnion Mounted Ball Valve
Ukwakheka kwama-valve ebhola enziwe ngezinto ze-titanium alloy ikakhulukazi kuhlanganisa izingxenye ezinjengemizimba yama-valve, izembozo zamavalvu, iziqu ze-valve, ama-sphere, nezihlalo zamavalvu. Isici esiyinhloko samavalvu ebhola le-titanium alloy ukumelana kwawo okuhle kakhulu nokugqwala, okungasebenza ngokujwayelekile emithonjeni eyonakalisayo ehlukahlukene njengama-acid aqinile, ama-alkali aqinile, nosawoti. Ngaphezu kwalokho, iphinde ibe nezinzuzo ezifana nokumelana nokushisa okuphezulu, ukumelana nokugqoka, nesisindo esincane, okwenza isetshenziswe kabanzi ezimbonini ezifana ne-petroleum, amakhemikhali, i-metallurgy, namandla. Umgomo wayo wokusebenza ukusebenzisa isiqu se-valve ukushayela ukujikeleza kwebhola, ukwakha iziteshi ezihlukene phakathi kwebhola nesihlalo se-valve, ngaleyo ndlela kuzuzwe ukuvuleka, ukuvala, nokulungiswa kwendawo. Lapho i-sphere ijikeleza ama-degree angu-90, okuphakathi kudlula ku-valve; Lapho i-sphere ijikeleza ama-degree angu-180, i-medium inqanyulwa ngokuphelele. Ukusebenza kwayo kokuvalwa kuncike kakhulu endaweni yokuxhumana phakathi kwendilinga kanye nesihlalo sevalvu kanye nokusebenza kwempahla yokuvala.

Izici Ezengeziwe
1. Ibhola lisekelwa ama-bearings angaphezulu naphansi, anciphisa ukungqubuzana futhi asuse i-torque eyeqile ekhiqizwa umthwalo omkhulu wokuvala owenziwe ukucindezela kwe-inlet ephusha ibhola nesihlalo sokuvala.
2. I-PTFE into eyodwa yokuvala indandatho ishumekwe esihlalweni sevalvu yensimbi engagqwali, futhi isiphethu sifakwa ekugcineni kwesihlalo sevalvu yensimbi ukuze kuqinisekiswe ukuthi indandatho yokuvala inamandla anele okuqinisa ngaphambili. Ngisho noma indawo yokuvala iguga ngesikhathi sokusetshenziswa, isengaqinisekisa ukusebenza kahle kokuvala ngaphansi kwesenzo sentwasahlobo.
3. Ukuze uvimbele ukuvela komlilo, indandatho yokuvala umlilo ifakwa phakathi kwe-sphere nesihlalo se-valve. Lapho indandatho yokuvala ishiswa, ngaphansi kwesenzo samandla entwasahlobo, indandatho yokuvala isihlalo se-valve iphushwa ngokushesha endaweni, yenze insimbi ibe sensimbi, ifinyelele umphumela othile wokuvala. Ukuhlolwa kokumelana nomlilo kuhlangabezana nezidingo zamazinga e-APl6FA kanye ne-APl607.
4. Uma ingcindezi yendawo evalelekile egumbini le-valve ikhuphuka ngokungavamile ngaphezu kwengcindezi yangaphambili yentwasahlobo, isihlalo sevalvu sizohlehla futhi siphume endimeni, kufinyelele umphumela wokukhululeka kokucindezela okuzenzakalelayo. Ngemuva kokukhululeka kwengcindezi, isihlalo se-valve sizolulama ngokuzenzakalelayo
5. Izimbobo zokukhipha amanzi zifakwe ezinhlangothini zombili ze-valve ukuze kuhlolwe ukuvuza esihlalweni. Ngesikhathi sokusebenza, lapho i-valve ivuliwe ngokugcwele noma ivaliwe ngokugcwele, ukucindezela ekamelweni eliphakathi kungasuswa futhi ukupakisha kungashintshwa ngokuqondile; Ingakwazi ukukhipha izinto ezisele ekamelweni eliphakathi futhi inciphise ukungcoliswa kwe-medium ku-valve.
6.Ngenxa yezinto zangaphandle phakathi nendawo noma umlilo obangela ukwehluleka ngengozi kophawu lwesihlalo se-valve, i-valve yamafutha inikeza ukuxhumana okusheshayo nesibhamu samafutha, kanye nepompo engenisiwe kalula futhi ngokushesha ijove i-grease yokuvala endaweni yokuvala isihlalo se-valve ukuze kuncishiswe ukuvuza.
7. Ngaphezu kokusetha izindandatho zokuvala ezijwayelekile, izigxivizo ze-O-ring nazo zifakwe ku-gland yokupakisha, iqinisekisa ukuthembeka kwe-valve stem seal ngokuvalwa okubili; Ukwengezwa kokupakishwa kwe-graphite nokufaka umjovo wamafutha kunciphisa ukuvuza kwesiqu se-valve ngemva komlilo. Ama-bearings ashelelayo kanye nama-thrust bears we-valve stem enza ukusebenza kwe-valve kube lula.
8. Izakhiwo ezibhorekile ezigcwele noma ezincishisiwe zingakhethwa njengoba kudingeka. Imbobo yokugeleza yevalvu egcwele ibhore iyahambisana nobubanzi bangaphakathi bepayipi, okwenza kube lula ukuhlanza ipayipi.
9. Ngokwezidingo zokufakwa noma zokusebenza, isiqu se-valve singanwetshwa. I-valve yebhola yenduku enwetshiwe, elungele kakhulu igesi yasemadolobheni nezinye izikhathi ezidinga ukubekwa kwepayipi eligqitshiwe. Ubukhulu besiqu se-valve esandisiwe buyonqunywa ngokwezidingo zekhasimende.
10. Ukusetshenziswa kwezihlalo kanye nama-stem bearings ane-coefficient encane yokungqubuzana kanye nezakhiwo ezinhle zokuzigcoba kunciphisa kakhulu i-torque yokusebenza ye-valve. Ngakho-ke, ngisho nangaphandle kokuhlinzeka ngamafutha okufaka uphawu, i-valve ingasebenza ngokuguquguqukayo nangokukhululekile isikhathi eside.
Izingxenye Eziyinhloko

Ukugcinwa kwe-titanium alloy valves.
Ukuqinisekisa ukusebenza kwayo okuvamile kanye nempilo yesevisi, i-valve kufanele igcinwe njalo futhi isetshenziswe.
1. Hlola njalo ukubukeka kwe-valve ukuze uqinisekise ukuthi ayinasici, umonakalo, nezinye izinkinga.
2. Gcoba njalo i-valve ukuze unciphise ukungqubuzana ngesikhathi sokusebenza kwe-valve futhi wandise impilo yayo yesevisi.
3. Hlanza njalo i-valve ukuze ususe ukungcola, idiphozithi, njll. ebusweni be-valve futhi uqinisekise ukusebenza kwayo kokuvala.
4. Yenza ukuhlolwa kwengcindezi njalo kumavalvu ukuze uqinisekise ukuthi ukuvala nokuphepha kwawo kuhlangabezana nezidingo.
Kafushane, ama-valve ebhola le-titanium alloy asetshenziswe kabanzi ezimbonini eziningi ngenxa yokumelana nokugqwala okuhle kakhulu, ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqoka, nezinye izakhiwo. Ukuqonda amaphuzu olwazi afanelekile wamavalvu ebhola le-titanium alloy kungasisiza ukuthi sikhethe kangcono futhi sisebenzise le valve esebenza kahle, sithuthukise ukusebenza kahle kokukhiqiza nokuphepha.
