Ama-valve e-globe nama-valve esango ama-valve amabili asetshenziswa kabanzi. Okulandelayo yisingeniso esiningiliziwe somehluko phakathi kwamavalvu embulunga namavalvu esango.
1. Izimiso zokusebenza zihlukile. Ivalvu yembulunga iwuhlobo lwesiqu esikhuphukayo, futhi isondo lesandla liyazungeza futhi likhuphuke ngesiqu se-valve. I-valve yesango iwukujikeleza kwesondo lesandla, futhi isiqu se-valve siyakhuphuka. Izinga lokugeleza lihlukile. I-valve yesango idinga ukuvuleka okugcwele, kodwa i-valve yembulunga ayifuni. I-valve yesango ayinazo izidingo zendlela yokungena neyokuphuma, futhi i-valve yembulunga inezindawo zokungena ezishiwo nezindawo zokuphuma! I-valve yesango elingenisiwe kanye ne-globe valve amavalvu avalayo futhi yiwona amabili ajwayeleke kakhulu.
2. Ngokombono wokubukeka, i-valve yesango ifushane futhi yinde kune-valve yembulunga, ikakhulukazi i-valve ye-stem ekhuphukayo idinga indawo ephakeme yokuphakama. Indawo yokuvala yevalvu yesango inekhono elithile lokuzivala, futhi umgogodla wayo wevalvu uxhumene ngokuqinile nendawo yokuvala isihlalo se-valve ngokucindezela okuphakathi ukuze kuzuzwe ukucinana nokungavuzi. I-valve core slope ye-valve yesango le-wedge ngokuvamile i-3 ~ 6 degrees. Lapho ukuvalwa okuphoqelekile kudlulele noma izinga lokushisa lishintsha kakhulu, i-valve core kulula ukunamathela. Ngakho-ke, izinga lokushisa eliphezulu kanye ne-high-pressure wedge gate valves athathe izinyathelo ezithile zokuvimbela umgogodla we-valve ukuthi ungabambeki esakhiweni. Lapho i-valve yesango ivuliwe futhi ivaliwe, i-valve core kanye nendawo yokuvala isihlalo se-valve ihlala ithintana futhi igudlana, ngakho-ke indawo yokuvala kulula ukugqoka, ikakhulukazi uma i-valve isesimweni esiseduze nokuvalwa, umehluko wengcindezi phakathi kwengaphambili nangemuva kwe-valve core mkhulu, futhi ukuguga kwendawo yokuvala kubi kakhulu.
3. Uma kuqhathaniswa ne-valve yembulunga engenisiwe, inzuzo enkulu ye-valve yesango ukuthi ukumelana nokugeleza kwamanzi kuncane. I-coefficient yokumelana nokugeleza kwe-valve yesango evamile icishe ibe ngu-0.08 ~ 0.12, kuyilapho i-coefficient yokumelana yevalvu yembulunga evamile icishe ibe ngu-3.5 ~ 4.5. Amandla okuvula nawokuvala mancane, kanti i-medium ingageleza ngezindlela ezimbili. Okubi kuyisakhiwo esiyinkimbinkimbi, ubukhulu obukhulu bokuphakama, nokuguga okulula kwendawo yokuvala. Indawo yokuvala ye-valve yembulunga kufanele ivalwe ngamandla aphoqelelwe ukuze kuzuzwe uphawu. Ngaphansi kwesilinganiso esifanayo, ingcindezi yokusebenza kanye nedivayisi yokushayela efanayo, i-torque yokushayela ye-valve yembulunga 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 zevalvu yembulunga zithintana kuphela lapho ivalwe ngokuphelele. Ukushelela okuhlobene phakathi komgogodla we-valve evaliwe kanye nendawo yokuvala kuncane kakhulu, ngakho ukuguga kwendawo yokuvala nakho kuncane kakhulu. Ukuguga kwendawo yokuvala ama-valve embulunga ngokuvamile kubangelwa ukuba khona kwemfucumfucu phakathi kwe-valve core nendawo evalekayo, noma ukukhuhla okuphakathi nendawo ngenxa yesimo sokuvaleka esixegayo. Lapho ufaka i-valve yembulunga, okuphakathi kungangena kusuka phansi kwe-valve core futhi kusukela phezulu. Inzuzo yokungena okuphakathi ukusuka phansi kwe-valve core ukuthi ukupakisha akukho ngaphansi kwengcindezi lapho i-valve ivaliwe, enganweba impilo yesevisi yokupakisha futhi ithathe indawo yokupakisha lapho ipayipi eliphambi kwe-valve lingaphansi. ingcindezi. Okubi kokungena okuphakathi kusuka phansi kwe-valve core ukuthi i-torque yokushayela ye-valve inkulu, cishe izikhathi ezingu-1.05 ~ 1.08 kunezokungena okuphezulu, amandla e-axial esiqwini se-valve sikhulu, futhi isiqu se-valve sikhulu. kulula ukugoba. Ngenxa yalesi sizathu, ukungena okuphakathi nendawo kusuka phansi kuvame ukufaneleka kuphela kumavalvu eglobhu anobubanzi obuncane obuncane, futhi amandla okusebenza okuphakathi nendawo kumongo wevalvu lapho ivalvu ivaliwe alinganiselwe angabi ngaphezu kwama-350Kg. Amavalvu eglobhu kagesi angenisiwe ngokuvamile asebenzisa indlela yokungena okuphakathi ukusuka phezulu. Ukungalungi kokungena okuphakathi kusuka phezulu kuphambene nje nendlela yokungena kusuka phansi.
5. Uma kuqhathaniswa namavalvu esango, izinzuzo zama-valve embulunga ziyisakhiwo esilula, ukusebenza kahle kokuvala, nokukhiqiza nokugcinwa kalula; ukungalungi ukumelana noketshezi olukhulu namandla amakhulu okuvula nokuvala. Amavalvu esango kanye namavalvu embulunga avuleke ngokugcwele futhi avaleke ngokugcwele. Asetshenziselwa ukusika noma ukuxhuma i-medium futhi ayifanele ukusetshenziswa njengama-valve alawula ukungenisa. Ububanzi bokusetshenziswa kwama-valve embulunga kanye nama-valve esango kunqunywa izici zawo. Eziteshini ezincane, lapho kudingeka ukuvala ukuvala okungcono, ama-valve embulunga avame ukusetshenziswa; emapayipini esitimu kanye namapayipi okuphakela amanzi anobubanzi obukhulu, amavalvu esango asetshenziswa ngoba ukumelana noketshezi ngokuvamile kuyadingeka ukuze kube kuncane.
