Izinto zesibini sokutywina, umgangatho wesibini sokutywina, uxinzelelo olukhethekileyo lwetywina, kunye neempawu ezibonakalayo zesixhobo esiphakathi, zezinye zezinto ezininzi ezinokuchaphazela indlela i-cryogenic.iivalve zebholaitywina.Ukusebenza kwevalvu kuya kuchaphazeleka kakhulu kwezi ziguquguqukayo.Impembelelo.Ukuqinisekisa ukusebenza rhoqo kwevalve, kufuneka iyilwe ngempembelelo yale miba engqondweni kangangoko kunokwenzeka.

Izinto zokutywina

Isixhobo sokutywina esinakho ukugqwetheka kumaqondo obushushu aphantsi kufuneka sithathelwe ingqalelo.Into yentsimbi iya kuncipha kwaye igqwese njengoko iqondo lobushushu lihla, lidala isithuba kwitywina kunye nokuhla koxinzelelo oluthile lwetywina, oluya kuchaphazela ukusebenza kokutywinwa.Ngoko ke, kubalulekile ukukhetha into efanelekileyo yokutywina ngelixa uphuhlisa isakhiwo sokutywina ukuze ukhusele ukutywinwa.Ukuze kuncitshiswe ukungqubuzana xa ivalve ivuliwe kwaye ivaliwe kwaye yandise ubomi bevalve, kunye nokunciphisa iindleko kunye nokuphucula ukusebenza kokutywinwa, indlela yokutywina ethambileyo, edibanisa isinyithi kunye nezinto ezingezizo ezentsimbi, isetyenziswa ngokuqhelekileyo kwi-LNG. izimo zokusebenza

Umgangatho wesibini wokutywinwa

Umphezulu wokulungiswa komphezulu wengqukuva kunye noburhabaxa bomphezulu womphezulu wokutywina zezona zalathisi ziphambili zomgangatho wesibini sokutywina.I-torque efunekayo ukuvula kunye nokuvala i-valve inokwehliswa, ubomi benkonzo yevalve bunokwandiswa, kunye nokusebenza kokutywinwa kwevalve kunokwandiswa ngokwenza i-sphere ibe yingqukuva kwaye igudiswe kumphezulu wayo.Ke ngoko, kubalulekile ukomeleza umgangatho wokusetyenzwa komphezulu wesibini sokutywina ngexesha loyilo.

Cina uxinzelelo oluthile

Uxinzelelo olusetyenziswa kwindawo yokutywina nge-intshi nganye yesikwere luyaziwa njengoxinzelelo oluthile lokutywina.Ukusebenza kokutywina, ukuthembeka, kunye nexesha lokuphila kwevalve yebhola zonke zichatshazelwa ngokuthe ngqo kubungakanani boxinzelelo oluthile lokutywina.Nangona kunjalo, uxinzelelo oluthile lwebhola yevalve alukho phezulu njengoko lunokuba njalo.Kwezinye iimeko, uxinzelelo oluphezulu lokutywina luluncedo ekutywineni, kodwa njengoko uxinzelelo oluthile lokutywina lunyuka, i-torque efunekayo ukuze isebenze i-valve nayo iya kunyuka, engafanelekanga ukutywinwa.Ivalve isebenza ngokuqhelekileyo.Ke, elinye icandelo elibalulekileyo loyilo lokutywinwa lobushushu obuphantsi kakhuluiivalve zebholalukhetho lokutywina uxinzelelo oluthile.

iipropathi eziphathekayo zesiphakathi

Isitywina siya kuchaphazeleka kwinqanaba elithile ngeempawu ezibonakalayo ze-medium, ezifana ne-viscosity yayo kunye nobushushu.Okokuqala, ukungena kwe-medium kuncipha ngokunyuka kwe-viscosity, okwenza kube nzima ukuvuza.Iimeko zobushushu obuphantsi kuxa iqondo lobushushu eliphakathi linempembelelo enkulu kwitywina.Ukuvuza kubangelwa kukuguqulwa kwesakhiwo sokutywina okuziswe kukutshintsha kobungakanani bamanye amacandelo okutywinwa.Itywina liya kutshatyalaliswa ngexesha elinye njengoko ukutshintshwa koxinzelelo lokutywinwa kwendawo yokutywina.Ngenxa yoko, umphumo wokushisa kufuneka uthathelwe ingqalelo xa ukwakhiwa kwesakhiwo sokutywinwa.
