Umehluko phakathi kwe-Ball Valve ne-Butterfly Valve
Umehluko omkhulu phakathi kwamavalve ovemvane namavalve ebhola ukuthi i-valve uvemvane ivuleke ngokugcwele noma ivalwe kusetshenziswa i-disc kuyilapho i-valve yebhola isebenzisa ibhola elingenalutho, elinezimbobo kanye ne-pivoting ukwenza lokho.Kokubili idiski yevalve uvemvane kanye nengqikithi yevalvu yevalvu yebhola kuzungeza i-eksisi yazo.I-valve yovemvane ingakwazi ukulawula ukugeleza ngezinga layo elivulekile kuyilapho i-valve yebhola ingalungile ukwenza lokhu.
I-valve ye-Butterfly ibonakala ngokuvula nokuvala ngokushesha, isakhiwo esilula kanye nezindleko eziphansi, kodwa ukuqina kwayo kanye namandla okuthwala akukuhle.Izici zama-valve ebhola zifana nalezo zama-valve esango, kodwa ngenxa yomkhawulo wevolumu nokumelana nokuvula nokuvala, kunzima ukuthi i-valve yebhola ibe ububanzi obukhulu.
Isimiso sesakhiwo sama-valve ovemvane siwenza afaneleke ngokukhethekile ukwenziwa abe ngama-diameter amakhulu.I-disc ye-valve ye-butterfly ifakwe ohlangothini lobubanzi bepayipi.Emgudwini we-cylindrical womzimba we-butterfly valve, i-disc izungeza i-axis.Uma iphendulwa ikota, ivalvu ivuleka ngokugcwele.I-valve yevemvane inesakhiwo esilula, izindleko eziphansi kanye nobubanzi obuguquguqukayo obubanzi.Ama-valve ebhola ngokuvamile asetshenziselwa uketshezi namagesi ngaphandle kwezinhlayiya nokungcola.Lawa ma-valve anokuncipha komfutho we-fluid encane, ukusebenza kahle kokuvala uphawu kanye nezindleko eziphezulu.
Uma kuqhathaniswa, ukubekwa uphawu kwe-valve yebhola kungcono kune-butterfly valve.Uphawu lwe-valve yebhola luncike ekucindezelweni kwendawo eyindilinga ngesihlalo se-valve isikhathi eside, okuqinisekile ukuthi sizogqoka ngokushesha kune-semi-ball valve.I-valve yebhola ngokuvamile yenziwe ngezinto zokuvala eziguquguqukayo, futhi kunzima ukuyisebenzisa ekushiseni okuphezulu kanye namapayipi okucindezela okukhulu.I-valve ye-butterfly inesihlalo senjoloba, esikude nokusebenza kwensimbi yokuvala kanzima kwama-semi-ball valves, ama-valve ebhola kanye nama-valve esango.Ngemuva kokusetshenziswa isikhathi eside kwe-valve ye-semi-ball, isihlalo se-valve sizoguga kancane, futhi singasetshenziswa ngokuqhubekayo ngokulungiswa.Lapho isiqu nokupakishwa kuvulwa futhi kuvalwe, isiqu sidinga kuphela ukuzungeza ukuphenduka kwekota.Uma kukhona uphawu lokuvuza, cindezela ibhawodi lendlala yokupakisha ukuze ubone ukuthi akukho ukuvuza.Kodwa-ke, amanye ama-valve asasetshenziswa ngokulambisa ngokuvuza okuncane, futhi ama-valve athathelwa indawo ukuvuza okukhulu.
Ngenqubo yokuvula nokuvala, i-valve yebhola isebenza ngaphansi kwamandla okubamba izihlalo ze-valve kuzo zombili iziphetho.Uma kuqhathaniswa ne-semi-ball valve, i-valve yebhola ine-torque enkulu yokuvula nokuvala.Futhi ubukhulu be-diameter obujwayelekile, umehluko osobala kakhulu wokuvula nokuvala i-torque.Ukuvulwa nokuvalwa kwe-valve ye-butterfly kubonakala ngokunqoba ukuguqulwa kwenjoloba.Kodwa-ke, kuthatha isikhathi eside ukusebenzisa ama-valve esango nama-globe valves futhi kuwumsebenzi onzima ukwenza lokho.
I-valve yebhola kanye ne-plug valve yohlobo olufanayo.i-valve yebhola kuphela enebhola elingenalutho ukulawula ukugeleza kulo.Ama-valve amabhola asetshenziswa kakhulu ukusika, ukusabalalisa kanye nokushintsha indlela yokugeleza kwe-medium kumapayipi.
