Ama-valves we-tlobs nama-varo valves ama-valves amabili asetshenziswa kabanzi. Lokhu okulandelayo ukwethulwa okuningiliziwe komehluko phakathi kwama-valves omhlaba kanye nama-valves wesango.
1. Izimiso ezisebenzayo zihlukile. I-valve ye-hlabamhlaba inguhlobo lwesiqu esikhuphukayo, nesandla sijikeleza futhi sikhuphuke ngesiqu se-valve. I-valurve valve ukujikeleza kwesandla, futhi kukhuphuka isiqu se-valve. Izinga lokugeleza lihlukile. I-GAY VALVVVE idinga ukuvulwa okugcwele, kepha i-valve ye-Globe Valve ayiwenzi. I-Valve Valve ayinazo izidingo ze-inlet kanye nokuphuma kwezindlela zokuhola, futhi i-valve ye-Global Valve ichaze ama-inlets nezitolo! I-Valve Valve engenisiwe kanye ne-valve ye-Globe Valve ngama-valves avaliwe futhi kukhona ama-valves amabili ajwayelekile kakhulu.
2. Kusuka endaweni yokubuka, i-valur valve ifushane futhi ide kune-valve ye-globe, ikakhulukazi i-valve ekhuphukayo idinga isikhala esiphakeme esiphakeme. Indawo yokubopha uphawu le-Valve Valve inekhono elithile lokuzazisa, futhi umnyombo wayo we-valve uhlangana ngokuqinile nesihlalo se-valve isihlalo sokuvalwa kwengcindezi ephakathi nendawo yokufeza ukuqina futhi akukho ukuvuvukala. I-Valve Core Slope ye-Wedge Gate Valve ngokuvamile i-3 ~ 6 degrees. Lapho ukuvalwa okuphoqelelwe kukhulu ngokweqile noma izinga lokushisa lishintsha kakhulu, i-valve core kulula ukuyibanjwa. Ngakho-ke, ama-valueve aphezulu okushisa kanye ne-high-pericumfutha ye-wedve athathe izinyathelo ezithile ukuvikela umnyombo we-valve ukuba anamathele esakhiweni. Lapho kuvulwa i-hatve valve futhi ivaliwe, i-valve core kanye nesihlalo se-valve seaning sihlala sithintana, ngakho-ke indawo yokubopha esondelana, ikakhulukazi lapho i-valve core ingaphezulu.
3. Uma kuqhathaniswa ne-valve ye-Global Valve engenisiwe, inzuzo eyinhloko ye-valve valve ukuthi ukulimala kokugeleza koketshezi kuncane. I-coufficience yokugeleza ye-Valve ejwayelekile ye-Valve ejwayelekile imayelana no-0.08 ~ 0.12, ngenkathi i-coeffient evamile yeGlobe Valve imayelana ne-3.5 ~,5. Amandla okuvulwa okusondelana anciphile, futhi okuphakathi kungageleza ngezindlela ezimbili. Ububi buyisakhiwo esiyinkimbinkimbi, usayizi omkhulu wokuphakama, nokugqoka okulula kwendawo yokubopha uphawu. Indawo yokubopha uphawu le-valve ye-Globalve Valve kumele ivalwe ngamandla aphoqelelwe ukufeza ukubekwa uphawu. Ngaphansi kwe-caliber efanayo, ingcindezi yokusebenza kanye nedivaysi efanayo yokushayela, i-torque yokushayela ye-globe valve yi-2,5 ~ 3.5 times times lesakhiwo sesango. Leli phuzu kufanele linake lapho elungisa indlela yokulawula i-torque ye-valve kagesi engenisiwe.
Okwesine, izindawo zokubopha uphawu zeGlobe Valve zithintana kuphela lapho zivalwa ngokuphelele. Isilinganiselo esihlobene phakathi kwesisekelo se-valve esivaliwe esivaliwe futhi indawo ebekelwe uphawu incane kakhulu, ngakho-ke ukugqokwa kwendawo yokubopha kuncane kakhulu. Ukugqokwa kwe-valve valve ebopha uphawu kudalwa kakhulu ukuba khona kwemfucumfucu phakathi komgogodla we-valve kanye nokubekwa uphawu okuphezulu, noma ukushaywa kwesivinini esikhulu se-lindow ngenxa yesimo sokuvala okuxekethile. Lapho ufaka i-valve ye-Globalbe, eliphakathi lingangena kusuka ezansi kwe-valve core nakuphezulu. Inzuzo yokungena okuphakathi kusuka phansi kwe-valve core ukuthi ukupakishwa akusekho ngaphansi kwengcindezi lapho i-valve ivaliwe, enganwebeka ngokupakisha lapho ipayipi liphambi kwe-valve lingaphansi kwengcindezi. Ukungathandeki kokungena okuphakathi okuvela phansi kwesisekelo se-valve ukuthi i-torque yokushayela ye-valve inkulu, cishe izikhathi eziyi-1.05 ~ 1.08 zokungena, futhi i-valve stem kulula ukuyiguqa. Ngalesi sizathu, ukungena okuphakathi okuvela phansi kuvame kuphela kuphela okulungele ama-valves amancane-ububanzi be-global valves, kanye namandla okusebenza okuphakathi kwe-valve emnyolweni we-valve lapho kuvalwe i-350kg. Ama-valves angenisiwe e-genner genem ngokuvamile asebenzisa indlela yokungena okuphakathi ukusuka phezulu. Ukungathandeki kokungena okuphakathi kusuka phezulu kuphambene nendlela yokungena kusuka phansi.
5 Okubi kungukumelana kwamanzi okukhulu kanye nokuvula okukhulu nokuvalwa kwamabutho. Ama-valves ama-galves nama-valves e-globe avuleke ngokuphelele futhi avale ngokuphelele ama-valve. Zisetshenziselwa ukusika noma ukuxhumanisa okuphakathi futhi azilungele ukusetshenziswa njenge-templative elawula ama-valve. Uhla lwesicelo se-Globe valves nama-valves ama-gate kunqunywa ngezimpawu zabo. Eziteshini ezincane, lapho kudingeka ukubekwa uphawu okungcono kokuvaliwe, ama-valves e-Global Vales ajwayele ukusetshenziswa; Emapanini akwamusi kanye namapayipi amanzi amakhulu ahlukahlukene, kusetshenziswa ama-varo valve ngoba ukumelana koketshezi ngokuvamile kuyadingeka ukuba kube mncane.
