Ingabe kunesidingo esiqinile sokuqondiswa kokufakwa kwama-valve ebhola?

Isiqondiso sokufakwa kwama-valve ebhola sincike ngokuqinile kuhlobo lwazo kanye nezici zokuklama. Okujwayelekile kakhuluama-valve ebholaayinayo imingcele yokuqondisa, kodwa izinhlobo ezikhethekile zidinga ukunamathela ngokuqinile esiqondisweni esibonisiwe sokufakwa. Ukuhlaziywa okuqondile kungokulandelayo:

Ama-valve ebhola ajwayelekile, njengama-valve ebhola antantayo ajwayelekile futhi agxilileama-valve ebhola, ngokuvamile ayinazo iziqondiso eziqinile zokufaka. Ingxenye yokuvula nokuvala yalolu hlobo lwe-valve yebhola yibhola elinesiteshi phakathi. Lapho i-valve yebhola isivuleke ngokugcwele, i-medium ingageleza icishe ingavimbeki isuka kunoma iyiphi indawo yeshaneli yebhola iye komunye umkhawulo. Umgomo wokuvala uncike ekutheni isihlalo se-valve sicindezelwe ngokuqinile ngokumelene ne-sphere ngaphansi kwe-pre tension noma i-medium pressure, kuzuzwe ukuvala uphawu kabili. Ngakho-ke, kokubili ukufakwa okuhle nokubi kungasebenza ngokujwayelekile. Isibonelo, ama-valve amabhola antantayo avame ukutholakala kumapayipi asendlini nawububanzi obuncane angahlangabezana nezidingo zokusetshenziswa uma efakwe kuzo zombili izinkomba ngaphandle kokulebula okukhethekile.

Nokho, kukhona ezinye izinhlobo ezikhethekileama-valve ebholaisiqondiso sayo sokufaka sibalulekile. Amavavu anophawu oluqondisayo azoba nemicibisholo eqoshwe ngokucacile emzimbeni we-valve ekhombisa isiqondiso sokugeleza kwe-medium, okusho ukuthi isakhiwo sangaphakathi se-valve siklanywe futhi senzelwe isiqondiso esithile sokugeleza. Ukufaka ukuhlehla kungase kuthinte umphumela wokuvala noma impilo yesevisi. Umnyombo we-valve yebhola elawulayo emise okwe-V unokuvulwa okumise okuka-V, okuklanyelwe ngokukhethekile ukulawula ukugeleza ngezidingo zokugeleza ezicacile. Ukufakwa kokuhlehla kungashintsha izici zokugeleza, okuholela ekulawuleni okungalungile kanye nokusheshiswa kokugqoka uphawu. Ama-valve ebhola anezindlela ezintathu namane anemigudu yokugeleza eyinkimbinkimbi futhi kufanele afakwe ngokulandela isiqondiso sokugeleza esiklanyelwe, ngaphandle kwalokho ukusabalalisa okuphakathi okunqunywe kusengaphambili noma umsebenzi wokushintsha awukwazi ukufezwa. Amavalvu ebhola anama-actuator, njengalawo afakelwe ama-actuator kagesi noma womoya, nakuba ivalvu ngokwayo ingase ibe-bi-directional, indawo emisiwe ye-actuator (evamise ukuvuleka noma evamise ukuvaleka) ixhumene nomklamo wesistimu yamapayipi. Ngesikhathi sokufakwa, kufanele kuqinisekiswe ukuthi i-valve isesimweni esidingekayo sokuphepha kwesistimu (ivuleke ngokugcwele noma ivalwe ngokugcwele) lapho i-actuator ivaliwe noma inqanyulwa.
