1. Iivalve yebholaivele kwivalve yeplagi.Inxalenye yayo yokuvula kunye nokuvala isebenza njenge-sphere, esebenzisa i-sphere ukujikeleza i-90 degrees malunga ne-axis ye-valve stem ukufezekisa injongo yokuvula nokuvala.
2. Umsebenzi wevalve yebhola
Ivalve yebhola isetyenziselwa ikakhulu ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba kwe medium kumbhobho.Ivalve yebhola eyenzelwe njengokuvulwa okumise okwe-V nayo inomsebenzi olungileyo wohlengahlengiso lokuhamba.
I-valve yebhola ayilula kuphela kwisakhiwo, ilungile ekusebenzeni kokutywinwa, kodwa kunye nobukhulu obuncinci, ubunzima bokukhanya, ukusetyenziswa kwezinto eziphantsi, ubungakanani obuncinci bokufaka, kunye ne-torque encinci yokuqhuba ngaphakathi kwinqanaba elithile lokuhamba.Kulula ukusebenza kwaye kulula ukufikelela ngokukhawuleza ukuvulwa nokuvala.Enye yeentlobo zevalve ezikhula ngokukhawuleza kwiminyaka engaphezu kweshumi.Ngokukodwa kumazwe ahambele phambili njengeUnited States, eJapan, eJamani, eFransi, eItali, eNtshona naseBritani, ukusetyenziswa kweevalvu zebhola kuninzi kakhulu, kwaye iintlobo kunye nobuninzi bokusetyenziswa ziyaqhubeka zisanda.Ubomi, ukusebenza ngokugqwesileyo kokulawula kunye nophuhliso lwemisebenzi emininzi yevalve, ukuthembeka kwayo kunye nezinye izalathisi zokusebenza ziye zafikelela kwinqanaba eliphezulu, kwaye ziye zatshintsha ngokuyinxenye iivalvu zesango, iivalve zokumisa, kunye neevalvu zokulawula.
Ngokuqhubela phambili kobuchwepheshe bevalve yebhola, kwixesha elifutshane elibonakalayo, kuya kubakho usetyenziso olubanzi ngakumbi kwimibhobho ye-oyile nerhasi, ukusulungekiswa kwe-oli kunye neeyunithi zokuqhekeka, kunye noshishino lwenyukliya.Ukongeza, iivalvu zebhola ziya kuba zezinye zeentlobo zevalve ezikhokelayo kwiikhalibhu ezinkulu neziphakathi kunye namabala oxinzelelo oluphantsi naphakathi kwamanye amashishini.
Iinzuzo ezi-3 zevalve yebhola
Inokumelana nokuqukuqela okusezantsi (eneneni inguziro)
Ngenxa yokuba ayiyi kuxinga ngexesha lomsebenzi (xa kungekho lubricant), inokusetyenziswa ngokuthembekileyo kwimithombo yeendaba ezonakalisayo kunye nolwelo oluphantsi.
Kuluhlu olukhulu loxinzelelo kunye nobushushu, ukutywinwa okupheleleyo kunokufezekiswa.
Iyakwazi ukuqonda ukuvulwa ngokukhawuleza kunye nokuvala, kwaye ixesha lokuvula kunye nokuvalwa kwezinye izakhiwo kuphela i-0.05-0.1s ukuqinisekisa ukuba ingasetyenziselwa inkqubo yokuzenzekelayo yebhentshi yokuvavanya.Xa uvula kwaye uvala i-valve ngokukhawuleza, akukho nkothuko ekusebenzeni.
Ubume bevalve yebhola
Isixhobo esisebenzayo sitywinwe ngokuthembekileyo kumacala omabini.
Xa ivuleke ngokupheleleyo kwaye ivalwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu yodwa ukusuka kumbindi, ngoko ke okuphakathi okudlula kwivalve ngesantya esiphezulu akuyi kubangela ukhukuliseko lomphezulu wokutywina.
Ngesakhiwo esincinci kunye nobunzima obulula, sinokuthathwa njengesona sakhiwo sevalve esinengqiqo kwiinkqubo zeendaba ze-cryogenic.
Umzimba wevalvu uyalingana, ngakumbi xa isakhi somzimba wevalve sidityanisiwe, esinokumelana kakuhle noxinzelelo lombhobho.
Isiqwenga sokuvala sinokumelana nokwahlukana koxinzelelo oluphezulu xa luvaliwe.
I-valve yebhola enomzimba odibeneyo inokuthi ingcwatywe ngokuthe ngqo emhlabathini, ukwenzela ukuba iindawo zangaphakathi ze-valve zingabonakali, kwaye ubomi benkonzo enkulu bunokufikelela kwiminyaka engama-30.Yeyona valve ifanelekileyo kwimibhobho yeoli kunye negesi yendalo.
Ngenxa yokuba ivalve yebhola ineenzuzo ezingentla, inoluhlu olubanzi lwezicelo.Ivalve yebhola ingasetyenziswa kwi: i-passage yegama ukusuka kwi-8mm ukuya kwi-1200mm.
Uxinzelelo oluqhelekileyo lusuka kwi-vacuum ukuya kwi-42MPa kunye nobushushu bokusebenza busuka kwi -204 ° C ukuya kwi-815 ° C.
