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, usayizi omkhulu wokuphakama, nokugqoka 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, okuphakathi nendawo okungena kusuka phansi ngokuvamile kulungele kuphela ama-valve eglobhu anobubanzi obuncane obuncane, futhi amandla e-medium esebenza kumongo wevalvu lapho ivalvu ivaliwe anomkhawulo wokungabi 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.
