Ungayiguqula kanjani i-Valve Pressure PSI, i-BAR ne-MPA?
Ukuguqulwa kwe-PSI kanye ne-MPA, i-PSI iyunithi yokucindezela, echazwa ngokuthi iphawundi yaseBrithani/intshi yesikwele, 145PSI = 1MPa, futhi i-PSI IsiNgisi ibizwa ngokuthi Amaphawundi ngesikwele ngasinye. Ungakwazi ukubala wonke amayunithi ngamayunithi omphakathi: 1bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895bar Europe ...Funda kabanzi -
Izici zokugeleza ze-valve yokulawula
Izici zokugeleza ze-valve yokulawula ikakhulukazi zihlanganisa izici ezine zokugeleza: umugqa oqondile, amaphesenti alinganayo, ukuvulwa okusheshayo kanye ne-parabola. Uma ifakwe kwinqubo yokulawula yangempela, ukucindezelwa okuhlukile kwe-valve kuzoshintsha ngokushintsha kwezinga lokugeleza. Okusho ukuthi, lapho...Funda kabanzi -
Asebenza kanjani ama-valve alawulayo, ama-globe valves, ama-valve esango namasheke
I-valve elawulayo, ebizwa nangokuthi i-valve yokulawula, isetshenziselwa ukulawula usayizi woketshezi. Lapho ingxenye elawulayo ye-valve ithola isignali elawulayo, isiqu se-valve sizolawula ngokuzenzakalelayo ukuvulwa nokuvalwa kwe-valve ngokuvumelana nesignali, ngaleyo ndlela ilawule izinga lokugeleza kwamanzi...Funda kabanzi -
Uyini umehluko phakathi kwe-valve yesango ne-butterfly valve?
Ama-valve esango kanye nama-valve uvemvane ama-valve amabili asetshenziswa kakhulu. Zihluke kakhulu ngokwezakhiwo zazo, izindlela zokuzisebenzisa, kanye nokuvumelana nezimo zokusebenza. Lesi sihloko sizosiza abasebenzisi baqonde kangcono umehluko phakathi kwama-valve esango nama-butterfly valves. Usizo olungcono...Funda kabanzi -
Umehluko omkhulu phakathi kwe-valve yokunciphisa ingcindezi kanye ne-valve yokuphepha
1. I-valve yokunciphisa ingcindezi iyi-valve enciphisa ukucindezela kokungena kungcindezi ethile edingekayo yokuphuma ngokulungiswa, futhi incike emandleni omthombo ngokwawo ukuze kugcinwe ngokuzenzakalelayo ukucindezela kokuphuma okuzinzile. Ngokombono we-fluid mechanics, ingcindezi enciphisa i-va...Funda kabanzi -
Isifinyezo somehluko phakathi kwamavalvu embulunga, amavalvu ebhola namavalvu esango
Ake sithi kunepayipi elihambisa amanzi elinekhava. Amanzi ajovwa kusukela phansi kwepayipi futhi akhishelwa emlonyeni wepayipi. Isembozo sepayipi lokuphuma kwamanzi lilingana nelungu lokuvala le-valve yokumisa. Uma uphakamisela ikhava yepayipi ngesandla sakho, amanzi azoba yidiski...Funda kabanzi -
Liyini inani le-CV yevalvu?
Inani le-CV igama lesiNgisi elithi Circulation Volume Isifinyezo sevolumu yokugeleza ne-flow coefficient sisuka encazelweni ye-valve coefficient emkhakheni wokulawula ubunjiniyela boketshezi eNtshonalanga. I-flow coefficient imelela umthamo wokugeleza we-elementi ukuya kokuphakathi, ukucaciswa...Funda kabanzi -
Ingxoxo emfushane ngomgomo wokusebenza kanye nokusetshenziswa kwama-valve positioners
Uma uhamba uzungeza indawo yokusebenzela yezitshalo zamakhemikhali, nakanjani uzobona amanye amapayipi afakwe ama-valve anamakhanda ayindilinga, angamavalvu alawulayo. Ivalvu elawula i-diaphragm yomoya Ungakwazi ukwazi olunye ulwazi mayelana nevalvu elawulayo egameni layo. Igama eliyisihluthulelo elithi “regulation ...Funda kabanzi -
Ukwethulwa kwenqubo yokukhipha ama-valve
Ukuphonswa kwe-valve yomzimba kuyingxenye ebalulekile yenqubo yokukhiqiza ama-valve, futhi ikhwalithi yokusakazwa kwe-valve inquma ikhwalithi ye-valve. Okulandelayo kwethula izindlela ezimbalwa zenqubo yokulingisa ezivame ukusetshenziswa embonini yamavalvu: Ukubunjwa kwesihlabathi: Ukubunjwa kwesihlabathi c...Funda kabanzi
