Amavalve ovemvane adlala indima ebalulekile uma kuziwa ekulawuleni ukugeleza koketshezi kumasistimu amapayipi. Kuzicelo zezimboni,PVC butterfly valveskuyisinqumo esidumile ngenxa yokuqina nokusebenza kahle kwazo. Kulesi sihloko, sizobheka ngokujulile imisebenzi yama-valve ovemvane, ikakhulukazi lawo enziwe nge-PVC, futhi sihlole ukuthi kungani ebalulekile ezimbonini ezihlukahlukene.

Umsebenzi we-valve uvemvaneilula kodwa ibaluleke kakhulu. Empeleni, ilawula ukugeleza koketshezi ngokusebenzisa idiski ebizwa ngokuthi “uvemvane” ephakathi nendawo yepayipi. Ngokungafani nama-valve ebhola, asebenzisa ibhola ukulawula ukugeleza, i-disc ye-butterfly valve ifakwe ku-shaft ejikelezayo. Lapho i-valve isendaweni evaliwe, i-disc i-perpendicular ekugelezeni kwamanzi, ivimbela ngokuphumelelayo uketshezi. Uma ivuliwe, i-disc ijikeleza ngokuhambisana nesiqondiso sokugeleza kwamanzi, okuvumela uketshezi ukuba ludlule.

Izinto ze-PVC zengeza olunye ungqimba lokusebenza nokuthembeka kumavalve ovemvane. I-PVC, noma i-polyvinyl chloride, iyi-thermoplastic enokumelana okuhle kwamakhemikhali futhi ifanele ukusetshenziswa okuhlukahlukene. Ngaphezu kokumelana namakhemikhali abolayo, i-PVC ayisindi, kulula ukuyifaka, futhi iyonga, iyenze ibe into efanelekile yamavalvu ovemvane.

Ama-valve evemvane e-PVC adumileezindaweni zezimboni lapho ukugeleza koketshezi olubolayo kuvame. Ikhono layo lokumelana namakhemikhali anokhahlo kanye nezinga lokushisa elibi kakhulu liyenza ibe yingxenye ebalulekile ezimbonini zokucubungula amakhemikhali, izindawo zokuhlanza amanzi kanye nezinhlelo zokulawula amanzi angcolile. Ukuqina nokuqina kwamavalvu ovemvane be-PVC kuqinisekisa ukuthi anganikeza isevisi yesikhathi eside, ethembekile ezindaweni ezidinga kakhulu.

Ngaphezu kwalokho, ama-valve evemvane e-PVC nawo asetshenziswa kabanzi ekuthuthweni kwamanzi nolunye uketshezi olungagqwali. Ingaphakathi layo elibushelelezi linciphisa ukwehla kwengcindezi kanye nesiyaluyalu, kuyenze ibe ukukhetha ukonga amandla okulawula uketshezi. Lokhu kwenza ama-valve ovemvane be-PVC abe yintandokazi ezinhlelweni ze-HVAC, izinhlelo zokunisela kanye namanethiwekhi okusabalalisa amanzi.

Esinye isici esibalulekile somsebenzi we-butterfly valves, kuhlanganise nalawo ayenziwe nge-PVC, yikhono labo lokulawula ukugeleza kwamanzi. Ngokulungisa i-angle ye-disc ngaphakathi kwe-valve, izinga lokugeleza lingalawulwa ngokunembile. Lokhu kwenza ama-valve ovemvane asebenziseke ngezindlela eziningi njengoba engasetshenziswa ukulawula ukugeleza koketshezi ezinqubweni ezihlukahlukene zezimboni, ukuqinisekisa ukusebenza kahle okuphelele nokusebenza kahle.

Kafushane, umsebenzi wama-valve ovemvane, ikakhulukazi lawo enziwe nge-PVC, ubaluleke kakhulu emkhakheni wokulawula uketshezi lwezimboni. Ikhono layo lokulawula ukugeleza koketshezi, ukumelana namakhemikhali abolayo futhi linikeze isevisi enokwethenjelwa liyenza ibe yingxenye ebalulekile ezimbonini eziningi. Kungakhathaliseki ukuthi ulawula ukugeleza kwamakhemikhali alimazayo endaweni yokucubungula noma ukulawula ukusatshalaliswa kwamanzi ezinhlelweni zikamasipala, amavalvu ovemvane e-PVC adlala indima ebalulekile ekuqinisekiseni ukuthi inqwaba yezinqubo zezimboni zihamba kahle nangempumelelo.
