Iivalvu zeglobe kunye neevalvu zesango ziivalvu ezimbini ezisetyenziswa kakhulu. Oku kulandelayo yintshayelelo eneenkcukacha ngomahluko phakathi kweevalvu zeglobe kunye neevalvu zesango.
1. Imigaqo yokusebenza yahlukile. Ivalvu yeglobhu luhlobo lwesiqu esinyukayo, kwaye ivili lesandla liyajikeleza lize linyuke kunye nesiqu sevalvu. Ivalvu yesango kukujikeleza kwevili lesandla, kwaye isiqu sevalvu siyaphakama. Isantya sokuhamba kwamanzi sahlukile. Ivalvu yesango ifuna ukuvulwa ngokupheleleyo, kodwa ivalvu yeglobhu ayifuni. Ivalvu yesango ayinazo iimfuno zokungena kunye nolwalathiso lokuphuma, kwaye ivalvu yeglobhu ineendawo zokungena kunye neendawo zokuphuma ezichaziweyo! Ivalvu yesango engenisiweyo kunye nevalvu yeglobhu ziivalvu ezivaliweyo kwaye zezona valvu zimbini zixhaphakileyo.
2. Ngokwembono yembonakalo, ivalvu yesango imfutshane kwaye inde kunevalvu yeglobe, ingakumbi ivalvu yesiqu esinyukayo ifuna indawo ephakamileyo yokuphakama. Umphezulu wokutywina wevalvu yesango unamandla athile okuzivalela, kwaye umongo wevalvu yawo unxibelelana ngokuqinileyo nomphezulu wokutywina isihlalo sevalvu ngoxinzelelo oluphakathi ukuze kufezekiswe ukuqina kunye nokuvuza. Umthambeka wevalvu yesango le-wedge ngokubanzi yi-3 ~ 6 degrees. Xa ukuvalwa okunyanzelekileyo kugqithisile okanye ubushushu butshintsha kakhulu, umongo wevalvu kulula ukunamathela. Ke ngoko, iivalvu zesango le-wedge ezinobushushu obuphezulu kunye noxinzelelo oluphezulu zithathe amanyathelo athile ukuthintela umongo wevalvu ukuba ungabambeki kwisakhiwo. Xa ivalvu yesango ivuliwe kwaye ivaliwe, umongo wevalvu kunye nomphezulu wokutywina isihlalo sevalvu zihlala zinxibelelana kwaye zigudlana, ngoko umphezulu wokutywina kulula ukuwunxiba, ngakumbi xa ivalvu ikwimeko ekufutshane nokuvala, umahluko woxinzelelo phakathi komphambili nomva womongo wevalvu mkhulu, kwaye ukugudla komphezulu wokutywina kunzulu ngakumbi.
3. Xa kuthelekiswa nevalvu yeglobe engeniswe ngaphakathi, inzuzo ephambili yevalvu yesango kukuba ukumelana nokuhamba kolwelo kuncinci. I-coefficient yokumelana nokuhamba kwevalvu yesango eqhelekileyo imalunga ne-0.08 ~ 0.12, ngelixa i-coefficient yokumelana kwevalvu yeglobe eqhelekileyo imalunga ne-3.5 ~ 4.5. Amandla okuvula nokuvala mancinci, kwaye i-medium inokugeleza ngeendlela ezimbini. Iingxaki zisakhiwo esintsonkothileyo, ubungakanani obukhulu bokuphakama, kunye nokuguguleka okulula komphezulu wokutywina. Umphezulu wokutywina wevalvu yeglobe kufuneka uvalwe ngamandla anyanzelekileyo ukuze kufunyanwe ukutywina. Phantsi kwe-caliber efanayo, uxinzelelo olusebenzayo kunye nesixhobo esifanayo sokuqhuba, i-torque yokuqhuba yevalvu yeglobe iphindwe kayi-2.5 ~ 3.5 kunevalvu yesango. Eli nqaku kufuneka liqwalaselwe xa kulungiswa indlela yokulawula i-torque yevalvu yombane engeniswe ngaphakathi.
Okwesine, iindawo zokutywina zevalvu yeglobe zidibana kuphela xa ivaliwe ngokupheleleyo. Ukutyibilika phakathi kwesiseko sevalvu esivalekileyo esinyanzelisiweyo kunye nomphezulu wokutywina kuncinci kakhulu, ngoko ke ukutyibilika komphezulu wokutywina nako kuncinci kakhulu. Ukutyibilika komphezulu wokutywina wevalvu yeglobe kubangelwa kakhulu bubukho benkunkuma phakathi kwesiseko sevalvu kunye nomphezulu wokutywina, okanye kukukhuhla ngesantya esiphezulu kwesixhobo ngenxa yemeko yokuvala ekhululekileyo. Xa ufaka ivalvu yeglobe, isixhobo singangena sisuka ezantsi kwesiseko sevalvu naphezulu. Inzuzo yesixhobo sokungena sisuka ezantsi kwesiseko sevalvu kukuba ukupakisha akukho phantsi koxinzelelo xa ivalvu ivaliwe, nto leyo enokwandisa ubomi benkonzo yokupakisha kwaye ithathe indawo yokupakisha xa umbhobho ophambi kwevalvu uphantsi koxinzelelo. Ukungalungi kwesixhobo sokungena sisuka ezantsi kwesiseko sevalvu kukuba i-torque eqhubayo yevalvu inkulu, malunga ne-1.05 ~ 1.08 amaxesha kunokungena okuphezulu, amandla e-axial kwisiqu sevalvu makhulu, kwaye isiqu sevalvu kulula ukusigoba. Ngenxa yesi sizathu, i-medium engena ukusuka ezantsi idla ngokufanelekela kuphela ii-valve zeglobe ezisebenzisa isandla ezinobubanzi obuncinci, kwaye amandla e-medium asebenza kwi-core yevalve xa ivalve ivaliwe anqunyelwe ukuba angadluli kwi-350Kg. Ii-valve zeglobe zombane ezingenisiweyo zihlala zisebenzisa indlela ye-medium engena ukusuka phezulu. Ingxaki ye-medium engena ukusuka phezulu ichasene nendlela yokungena ukusuka ezantsi.
5. Xa kuthelekiswa neevalvu zesango, iingenelo zeevalvu zeglobe zilula ulwakhiwo, ukusebenza kakuhle kokuvala, kunye nokuveliswa kunye nokugcinwa okulula; iingxaki kukumelana okukhulu kolwelo kunye namandla amakhulu okuvula nokuvala. Iivalvu zesango kunye neevalvu zeglobe zivuleke ngokupheleleyo kwaye zivalwe ngokupheleleyo. Zisetyenziselwa ukusika okanye ukudibanisa i-medium kwaye azifanelekanga ukusetyenziswa njengeevalvu ezilawula ukungenisa. Uluhlu lokusetyenziswa kweevalvu zeglobe kunye neevalvu zesango lumiselwa ziimpawu zazo. Kwimijelo emincinci, xa kufuneka ukuvala okungcono, iivalvu zeglobe zihlala zisetyenziswa; kwimibhobho yomphunga kunye nemibhobho yokuhambisa amanzi enobubanzi obukhulu, iivalvu zesango ziyasetyenziswa kuba ukumelana kolwelo ngokubanzi kufuneka kube kuncinci.
