Ukukhethwa kanye nezinzuzo kanye nokubi kwe-valve yembulunga kanye ne-valve yesango emkhakheni wesicelo

Ama-valve e-globe nama-valve esango yizinhlobo ezimbili ezivamile zama-valve, anezinhlobonhlobo zezinhlelo zokusebenza emkhakheni wokulawula uketshezi. Naphezu kwezindima zabo ezifanayo, ekusetshenzisweni okungokoqobo, banezinzuzo zabo kanye nokubi, ngakho ukukhetha uhlobo lwe-valve olufanele kubalulekile ukuze kuqinisekiswe ukusebenza okuvamile kwesistimu yamapayipi. Leli phepha lizohlaziya ukukhetha kanye nezinzuzo kanye nokubi kwe-valve yembulunga kanye ne-valve yesango emkhakheni wesicelo ngokombono wochwepheshe. Okokuqala, ukukhetha inkambu yokufaka isicelo 1. I-valve yokumisa Isakhiwo sevalvu yembulunga ilula uma kuqhathaniswa, ngokuyinhloko ifaneleka ohlelweni lwamapayipi anobubanzi obuncane naphakathi, futhi ukusebenza kwayo kokuvala kubi kakhulu. Ngakho-ke, esimweni sokusebenza kokuvalwa okuphezulu, kufanele kukhethwe ngokucophelela. Amavalvu eglobhu ngokuvamile asetshenziswa ezimweni ezilandelayo: - Lawula ukugeleza kwemithombo yezindaba ehlukahlukene yoketshezi; - Lawula isiqondiso ukugeleza medium; - Sika noma uxhume ipayipi. 2. I-valve yesango Isakhiwo se-valve yesango siyinkimbinkimbi, silungele uhlelo lwamapayipi obubanzi obukhulu, ukusebenza kwawo kokuvala kungcono. Ngakho-ke, esimweni sokusebenza kokuvala okuphezulu, i-valve yesango iyisinqumo esingcono. Amavalvu esango ngokuvamile asetshenziswa kulezi zimo ezilandelayo: - Lawula ukugeleza okuphakathi ngamapayipi amakhulu ububanzi; - Izikhathi ezidinga ukusebenza kokuvalwa okuphezulu, njengezinga lokushisa eliphezulu, umfutho ophakeme, imidiya evuthayo kanye neziqhumane; - Lungisa izinga lokugeleza kwe-medium. Okwesibili, ukuqhathanisa izinzuzo kanye nebubi 1. Isakhiwo kanye nokusebenza - I-valve ye-Globe: isakhiwo esilula, ukusebenza okulula, kodwa ukusebenza kokubeka uphawu kumbi kakhulu; I-valve yesango: isakhiwo siyinkimbinkimbi, ukusebenza kuyinkimbinkimbi, kodwa ukusebenza kokubeka uphawu kuhle. 2. Inkambu yohlelo lokusebenza - Ivalvu yeglobhu: ilungele amapayipi amancane naphakathi nendawo, ikhono lokulawula ukugeleza alinamandla; - Ivalvu yesango: ifanele ipayipi elikhulu lobubanzi, ikhono lokulawula ukugeleza liqinile. 3. Ukunakekela - Ivalvu yeglobhu: ukunakekela kulula, kodwa i-gasket idinga ukushintshwa njalo; - I-valve yesango: Ukugcinwa kuyinkimbinkimbi, kodwa ukusebenza kokubeka uphawu kuhle, futhi impilo yesevisi yinde. 4. Inani - I-valve yeglobhu: intengo iphansi kakhulu; - I-valve yesango: Intengo ephezulu uma kuqhathaniswa. Iii. Isiphetho Lapho ukhetha i-valve yembulunga kanye ne-valve yesango emkhakheni wokufaka isicelo, kufanele kucatshangelwe kabanzi ngokuya ngezimo ezithile zokusebenza, usayizi wepayipi, izici eziphakathi nendawo, izidingo zokuvala uphawu nezinye izici. Ngokusebenza okungokoqobo, kufanele sidlale ngokugcwele izinzuzo zabo futhi sinqobe ukushiyeka kwabo ukuze siqinisekise ukusebenza okuphephile, okuthembekile nokusebenza kahle kwesistimu yamapayipi.
