Umehluko phakathi kweValve Yevemvane Ehlezi Eqinile kanye Nevaluvu Yevemvane Ehlezi Ensimbi
Ama-valve e-Butterfly, anesakhiwo esihlangene, umklamo olula, ukusebenza kahle, nokugcinwa kalula.
Zingenye yama-valve ezimbonini ezidume kakhulu.
Sivamise ukuba nama-valve ovemvane ahlezi eqinile, noma ama-valve uvemvane anerabha afakwe ulayini werabha. Kulesi sigaba, sinamavalvu ovemvane anerabha eyisilutshwana, amavalvu ovemvane anerabha enerabha, amavalvu ovemvane anohlobo lwerabha anerabha ephindwe kabili kanye namavalvu ovemvane ane-flange ephindwe kabili.
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 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 ne-plug valve zohlobo olufanayo.i-valve yebhola kuphela enebhola elingenalutho ukulawula ukugeleza kulo.Ama-valve amabhola asetshenziswa kakhulu ukusika, ukusabalalisa kanye nokushintsha indlela yokugeleza kwe-medium kumapayipi.
Ivalve yevemvane ye-offset kathathu
Zombili izindawo zokuvala zama-valve ziyinsimbi noma ezinye izinto eziqinile, ezingasebenzi kahle kangako zokuvala, kodwa ezinezici ezinhle zemishini, ezinjengokumelana nezinga lokushisa eliphezulu kanye nokungagugi.
Ngokuvamile, kunomehluko olandelayo wamavalvu ovemvane ezihlalo ezimbili ezihlukene.
<1> Isakhiwo Esihlukile
Idizayini yomugqa omaphakathi yevalve uvemvane ehlezi eqinile kuyilapho idizayini emfishane ephindwe kabili noma kathathu yevalve uvemvane ehlezi.
<2> Izinga lokushisa elifanele elihlukile
sisebenzisa i-valve uvemvane ehlezi eqinile ekushiseni okujwayelekile, kuyilapho i-valve uvemvane ehlezi i-Metal isetshenziswa ekushiseni okuphansi, okujwayelekile nokuphezulu.
<3> Ingcindezi ehlukile
I-valve uvemvane ehlezi eqinile ilungele ukucindezela okuphansi nokujwayelekile kanye ne-Metal ehlezi uvemvane valvu nayo ingafanelana nomfutho ophakathi nendawo ophezulu.
<4> Ukusebenza okuhlukile kokuvala
I-valve uvemvane ehlezi eqinile kanye ne-Metal ehlezi uvemvane iveve inokusebenza okuhle kokuvala ngokuqhathaniswa.Eyakamuva ingavaleka kahle ngomfutho ophezulu kanye nezinga lokushisa.
