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 -
Ingcindezi ye-PN kanye namaphawundi Ekilasi ( Lb )
Ukucindezela okuzisholo (i-PN), izinga lephawundi elijwayelekile le-Class American ( Lb ), kuyindlela yokuveza ingcindezi, umehluko wukuthi ingcindezi abayimele ihambisana nezinga lokushisa elihlukile lereferensi, uhlelo lwe-PN European lubhekisela ekucindezelweni okungu-120 ° C. ingcindezi ehambisanayo, kuyilapho i-Class...Funda kabanzi -
Ukuhlaziywa kwezimbangela ezine eziyinhloko zokuvuza kwama-valve ebhola kanye nezindlela zokubhekana nazo
Ngokuhlaziywa kwesimiso sesakhiwo se-valve yebhola yephayiphi engashintshi, kwatholakala ukuthi isimiso sokuvala siyafana, kusetshenziswa isimiso “somphumela we-piston,” futhi isakhiwo sokuvala kuphela esihlukile.I-valve ekusetshenzisweni kwenkinga ibonakala ikakhulukazi ezinhlobonhlobo ...Funda kabanzi -
Ungakhetha kanjani phakathi kwe-concentric, i-double eccentric kanye ne-valve butterfly eccentric kathathu?
Umehluko esakhiweni se-valve uvemvane uhlukanisa izinhlobo ezine zamavalve ovemvane, okungukuthi: i-valve uvemvane olugxilile, i-valve uvemvane oluyi-eccentric olulodwa, i-valve uvemvane olune-eccentric kabili kanye ne-valve uvemvane eccentric kathathu.Uyini umqondo walokhu kugqama?Unganquma kanjani...Funda kabanzi
