Amavalvu e-globe namavalvu esango kungamavalvu amabili asetshenziswa kabanzi. Okulandelayo isingeniso esiningiliziwe somehluko phakathi kwamavalvu e-globe namavalvu esango.
1. Izimiso zokusebenza zihlukile. I-globe valve uhlobo lwesiqu esikhuphukayo, futhi isondo lesandla liyajikeleza futhi likhuphuke kanye nesiqu se-valve. I-gate valve iwukujikeleza kwesondo lesandla, futhi i-valve stem iyakhuphuka. Izinga lokugeleza lihlukile. I-gate valve idinga ukuvulwa okugcwele, kodwa i-globe valve ayifuni. I-gate valve ayinazo izidingo zokungena kanye nesiqondiso sokuphuma, futhi i-globe valve inezindawo zokungena kanye nezindawo zokuphuma ezicacisiwe! I-gate valve engenisiwe kanye ne-globe valve kungama-valve avaliwe futhi yiwona ma-valve amabili avame kakhulu.
2. Ngokombono wokubukeka, ivalvu yesango imfushane futhi iphakeme kunevalvu yomhlaba, ikakhulukazi ivalvu yesiqu esikhuphukayo idinga isikhala sokuphakama esiphezulu. Ubuso bokuvala bevalvu yesango bunekhono elithile lokuzivala, futhi umongo wayo wevalvu uxhumene ngokuqinile nobuso bokuvala isihlalo sevalvu ngokucindezela okuphakathi ukuze kufezwe ukuqina futhi kungabikho ukuvuza. Umthamo wokuvala wevalvu yesango le-wedge ngokuvamile ungama-degree angu-3 ~ 6. Uma ukuvalwa okuphoqelelwe kukhulu noma izinga lokushisa lishintsha kakhulu, umongo wevalvu kulula ukubhajwa. Ngakho-ke, amavalvu esango le-wedge anezinga lokushisa eliphezulu kanye nomfutho ophezulu athathe izinyathelo ezithile zokuvimbela umongo wevalvu ukuthi ungabhajwa esakhiweni. Lapho ivalvu yesango ivulwa futhi ivaliwe, umongo wevalvu kanye nobuso bokuvala isihlalo sevalvu zihlala zithintana futhi zigudlana, ngakho-ke indawo yokuvala kulula ukuyigqoka, ikakhulukazi lapho ivalvu isesimweni esiseduze nokuvala, umehluko wokucindezela phakathi kwangaphambili nangemuva komongo wevalvu mkhulu, futhi ukuguguleka komongo wokuvala kubi kakhulu.
3. Uma kuqhathaniswa ne-globe valve engenisiwe, inzuzo enkulu ye-gate valve ukuthi ukumelana nokugeleza koketshezi kuncane. I-coefficient yokumelana nokugeleza kwe-valve yesango evamile icishe ibe ngu-0.08 ~ 0.12, kanti i-coefficient yokumelana ye-globe valve evamile icishe ibe ngu-3.5 ~ 4.5. Amandla okuvula nokuvala mancane, futhi i-medium ingageleza ngezindlela ezimbili. Okubi yisakhiwo esiyinkimbinkimbi, ubukhulu obukhulu bokuphakama, kanye nokuguguleka okulula kwendawo yokuvala. Indawo yokuvala ye-globe valve kumele ivalwe ngamandla aphoqelelwe ukuze kufezwe ukuvalwa. Ngaphansi kwe-caliber efanayo, ingcindezi yokusebenza kanye nedivayisi efanayo yokushayela, i-torque yokushayela ye-globe valve iphindwe izikhathi ezingu-2.5 ~ 3.5 kune-valve yesango. Leli phuzu kufanele linakwe lapho kulungiswa indlela yokulawula i-torque ye-valve kagesi engenisiwe.
Okwesine, izindawo zokuvala ivalvu yomhlaba zithintana kuphela uma ivaliwe ngokuphelele. Ukushelela okuhlobene phakathi kwe-valve core evalwe ngenkani kanye nendawo yokuvala kuncane kakhulu, ngakho-ke ukuguguleka kwendawo yokuvala nakho kuncane kakhulu. Ukuguguleka kwendawo yokuvala ivalvu yomhlaba kubangelwa kakhulu ukuba khona kwemfucumfucu phakathi kwe-valve core kanye nendawo yokuvala, noma ukukhuhla okusheshayo kwe-medium ngenxa yesimo sokuvala esikhululekile. Lapho ufaka ivalvu yomhlaba, i-medium ingangena isuka phansi kwe-valve core futhi isuka phezulu. Inzuzo ye-medium engena isuka phansi kwe-valve core ukuthi ukupakisha akucindezelwa lapho ivalvu ivaliwe, okungandisa impilo yenkonzo yokupakisha futhi kuthathe indawo yokupakisha lapho ipayipi eliphambi kwevalvu lingaphansi kwengcindezi. Ububi be-medium engena isuka phansi kwe-valve core ukuthi i-torque eshayelayo yevalvu inkulu, cishe izikhathi ezingu-1.05 ~ 1.08 kuneyokungena okuphezulu, amandla e-axial esiqwini sevalvu makhulu, futhi isiqu sevalvu kulula ukusigoba. Ngenxa yalesi sizathu, i-medium engena isuka phansi ngokuvamile ifaneleka kuphela kuma-globe valve amancane aphathwa ngesandla, futhi amandla e-medium asebenza enkabeni ye-valve lapho i-valve ivaliwe anqunyelwe ku-350Kg. Ama-globe valve kagesi angenisiwe ngokuvamile asebenzisa indlela ye-medium engena isuka phezulu. Ububi be-medium engena isuka phezulu buphambene nendlela yokungena isuka phansi.
5. Uma kuqhathaniswa nama-valve esango, izinzuzo zama-valve e-globe ziyisakhiwo esilula, ukusebenza kahle kokuvala, kanye nokukhiqizwa nokugcinwa okulula; izinkinga ukumelana okukhulu koketshezi kanye namandla amakhulu okuvula nokuvala. Ama-valve esango nama-valve e-globe avuleke ngokuphelele futhi avalwe ngokuphelele. Asetshenziselwa ukusika noma ukuxhuma i-medium futhi awafanele ukusetshenziswa njengama-valve alawula ukungenisa. Uhla lokusetshenziswa kwama-valve e-globe nama-valve esango lunqunywa izici zawo. Eziteshini ezincane, lapho kudingeka ukuvala okungcono, ama-valve e-globe avame ukusetshenziswa; kumapayipi omusi kanye namapayipi amanzi anobubanzi obukhulu, kusetshenziswa ama-valve esango ngoba ukumelana koketshezi ngokuvamile kudingeka kube kuncane.
