Ama-valve ovemvane ayizici ezibalulekile ekusebenzeni okuhlukahlukene kwezimboni.Zinomsebenzi wokuvala uketshezi nokulawula ukugeleza.Ngakho ukwazi isimo samavalve ovemvane phakathi nokusebenza—kungakhathaliseki ukuthi avuliwe noma avaliwe—kubalulekile ekusetshenzisweni ngokuphumelelayo nasekunakekeleni kwawo.
Ukunquma ukuthi i-valve uvemvane ivulekile noma ivaliwe kuncike ngokuyinhloko ekuboneni nasezikhombi.Uma i-actuator ingesona isibambo, indlela ipuleti le-valve elihamba liye phezulu naphansi lihlukile kwamanye ama-valve esango elikhuphukayo kanye nama-valve eglobhu (ama-valve esango le-stem akhuphukayo adinga kuphela ukubuka ukuphakama kwesiqu se-valve ukuze kunqunywe ukuthi indawo ye-valve plate).Ama-valve ovemvane ahlukile I-disc ye-valve ingazungezisa 0-90° emzimbeni wevalvu ukuze iguqule ukugeleza koketshezi.
Nansi indlela yokubona indawo yepuleti levemvane levalve uvemvane:
1. I-Visual inspection-toothed disc:
Amavalvu ovemvane amancane, DN ≤ 250, angahlonywa ngezibambo namadiski anamazinyo.Njengoba igama liphakamisa, i-toothed disc ngokuvamile inezikali eziyi-10, eyokuqala ivalwe ngokugcwele, kanti eyokugcina ivuleke ngokugcwele.
Isikhundla esivulekile: Uma ivuliwe ngokugcwele, i-valve disc ihambisana nesiqondiso sokugeleza, okuvumela isiteshi samanzi ukuba singavinjelwa.
Indawo evaliwe: Esimeni esivaliwe, i-valve disc yenza ukuvinjelwa okuqondile oketshezini futhi imise ukunyakaza koketshezi.
2. Inkomba yesikhundla:
Ama-valve amaningi ovemvane afakwe izinkomba zangaphandle njengemicibisholo noma izimpawu ekhanda le-turbine.Lezi zinkomba zihambisana nezimpawu ezithile ezibonisa indawo yevalvu.
3. Isignali yempendulo:
Ezinhlelweni ezithuthukisiwe, amasignali empendulo avela kuzinzwa noma amaswishi ahlanganiswe kumshini wevalvu, anikeze ulwazi lwesikhathi sangempela mayelana nesimo sevalvu.
4. Ukuqapha okukude:
Ukufakwa kwezimboni zesimanje kungase kusebenzise amasistimu okuqapha akude avumela opharetha ukuthi bahlole bekude isimo samavalvu ovemvane futhi bathuthukise ukulawula nokugadwa.
Ukuqinisekisa ukuma kwe-valve butterfly ngendlela efanele kubalulekile ekugcineni ubuqotho benqubo, ukuvimbela ukuvuza kanye nokwenza kahle ukusebenza kahle.Izinqubo zokuhlola nokugcinwa njalo kufanele zifake ukuqinisekiswa kwesimo salawa mavalvu ukuze kuncishiswe ubungozi nokugcina ukusebenza kwesistimu.
Ukufingqa, ukukhomba ukuthi i-valve uvemvane ivuliwe noma ivaliwe ikakhulukazi kuncike ezinkomba ezibukwayo nezobuchwepheshe.Ukuqonda lezi zinkomba kubalulekile ekulawuleni ngempumelelo ama-valve kanye nokusebenza kwezimboni.
