Ama-valve esango ayizici ezibalulekile ezilawula ukugeleza koketshezi ezinhlobonhlobo zezinhlelo, futhi ukuqonda umehluko phakathi kwezinhlobo ezahlukene zamavalvu esango kubalulekile ekukhetheni i-valve yesango efanele yohlelo oluthile. Kule bhulogi, thina'ngizongena phakathi komehluko phakathi kwe-NRS (isiqu esibuyiselwe emuva) kanye namavalvu esango e-OS&Y (afakwe ngaphandle nejoka), ecacisa izici zawo eziyingqayizivele nezindlela ezisetshenziswayo.
Amavalvu esango le-NRS aklanywe ngesiqu esifile, okusho ukuthi isiqu asiyi phezulu noma phansi lapho ivalvu isebenza. Lawa mavalvu avame ukusetshenziselwa ukulawula ukugeleza kwamanzi ezinhlelweni zokufafaza lapho izithiyo zesikhala noma ukufakwa ngaphansi komhlaba kwenza ukusetshenziswa kwamavalvu esango aneziqu ezikhuphukayo kungenzeki. Amavalvu esango le-NRS ayatholakala nge-2" nut esebenzayo noma isondo lesandla ozikhethela lona, elinikeza ukuguquguquka kokuthandwa yikhasimende.
Amavalvu esango le-OS&Y, ngakolunye uhlangothi, afaka isikulufu sangaphandle nomklamo wejoka onesiqu esibonakala ngaphandle kwevalvu futhi sisebenza ngomshini wejoka. Lolu hlobo lwe-valve yesango ngokuvamile lufakwe i-wedge eqinile kanye nesiqu esifakwe ngaphambili sokukhweza iswishi yokuqapha. Idizayini ye-OS&Y ivumela ukuhlolwa okubonakalayo okulula kokusebenza kwamavalvu kanye nokuba lula kokwengeza izisetshenziswa ngezinjongo zokuqapha nokulawula.
Izici eziphawulekayo:
Umehluko oyinhloko phakathi kwe-NRS namavalvu esango le-OS&Y ukuklama kwesiqu nokubonakala. Amavalvu esango le-NRS aneziqu ezifihliwe zokusetshenziswa lapho isikhala silinganiselwe noma i-valve ifakwe ngaphansi komhlaba. Ngokuphambene, amavalvu esango le-OS&Y anesiqu esibonakalayo esiya phezulu naphansi lapho i-valve isebenza, okuvumela ukuqapha okulula nokwengeza iswishi yokuqapha.
Isicelo:
Ama-valve esango le-NRSzivame ukusetshenziswa ezinhlelweni zokusabalalisa amanzi angaphansi komhlaba, izinhlelo zokuvikela umlilo kanye nezinhlelo zokunisela lapho ukulawulwa kokusebenza kwe-valve kuyadingeka ngaphandle kwesidingo sokuhlola okubonakalayo okuqhubekayo. Ngakolunye uhlangothi, amavalvu esango le-OS&Y, akhethwa ezinhlelweni ezidinga ukugadwa nokugcinwa njalo, njengezinqubo zezimboni, izinhlelo ze-HVAC, nezitshalo zokuhlanza amanzi.
Khetha i-valve efanele:
Uma ukhetha phakathi kwamavalvu esango e-NRS kanye ne-OS&Y, kubalulekile ukucabangela izidingo ezithile zohlelo lokusebenza. Izinto ezinjengezingqinamba zesikhala, ukunethezeka kokulungiswa, kanye nezidingo zokuqapha ezibonakalayo zizonquma uhlobo lwevalvu yesango elifaneleka kakhulu ukusetshenziswa okuhlosiwe.
Kafushane, ukuqonda umehluko phakathi kwe-NRS namavalvu esango le-OS&Y kubalulekile ekwenzeni isinqumo esinolwazi lapho kukhethwa ivalvu elungile yohlelo oluthile. Ngokucabangela imisebenzi eyingqayizivele kanye nokusetshenziswa kohlobo ngalunye, onjiniyela nabaklami besistimu bangaqinisekisa ukuthi ama-valve amasango afinyelela ukusebenza okuphelele nokusebenza ezinhlelweni zabo.
