I-PVC Hlola I-Valve Isimiso Izinto Eziyisisekelo

I-PVC (i-polyvinyl chloride) ne-UPVC (i-polyvinyl chloride engafakwanga ipulasitiki) yizinto ezisetshenziswa kakhulu ekwenziweni kwamavalvu nokufakwa. Lezi zinto ziyaziwa ngokuqina kwazo, ukumelana namakhemikhali, kanye nokuthengeka kwazo, okuzenza zibe yizinketho ezidumile ezinhlotsheni eziningi zezinhlelo zokusebenza, okuhlanganisa amapayipi, ukuchelela, nezinqubo zezimboni.

Enye yezingxenye ezibalulekile ohlelweni lwamapayipi lwe-PVC noma lwe-UPVC yivalvu yokuhlola. Lolu hlobo lwe-valve luklanyelwe ukuvumela uketshezi ukuthi lugeleze luye ohlangothini olulodwa kuyilapho luvimbela ukugeleza okubuyela emuva. Ukuqonda isimiso ngemuva kwama-valve okuhlola e-PVC nokufakwa kwawo kubalulekile ukuze kuqinisekiswe ukusebenza kahle kohlelo lwamapayipi.

Isimiso se-valve yokuhlola i-PVC silula. Iqukethe umzimba we-valve one-inlet ne-outlet, kanye nendlela ephathekayo, njengebhola, i-disc, noma i-diaphragm, evumela ukugeleza ohlangothini olulodwa ngenkathi iyivimbele kwelinye icala. Lapho uketshezi lugeleza ngendlela efanele, umshini uyavuleka, uvumele uketshezi ukuba ludlule. Kodwa-ke, lapho ukugeleza kuhlehla, umshini uyavala, uvimbele ukugeleza emuva.

Ngaphezu kwe-valve ngokwayo, okokufakwayo okusetshenziswe ngokuhambisana nama-valve okuhlola e-PVC kudlala indima ebalulekile ekusebenzeni okuphelele kohlelo. Ukufakwa okufana nama-couplings, izindololwane, nama-tee asetshenziselwa ukuxhuma i-valve yokuhlola ohlelweni lwamapayipi kanye nokuqinisekisa ukuqondana nokusekelwa okufanele. Kubalulekile ukukhetha okokufaka okuhambisana nezinto ze-PVC noma ze-UPVC futhi eziklanyelwe ukumelana nezimo zokucindezela nokugeleza kwesistimu.

Lapho ukhetha ama-valve okuhlola i-PVC noma i-UPVC nokufakwa, kubalulekile ukucabangela izidingo ezithile zohlelo lokusebenza. Izinto ezinjengohlobo loketshezi oludluliswayo, ingcindezi yokusebenza nezinga lokushisa, kanye nezinga lokugeleza kuzoba nomthelela ekukhethweni kwevalvu efanele kanye nezixhumi. Ukwengeza, kubalulekile ukuqinisekisa ukuthi izingxenye zihlangabezana namazinga nemithetho yemboni ukuze kuqinisekiswe ukuphepha nokuthembeka kwesistimu.

Ukufakwa kwama-valve okuhlola i-PVC nokufakwa kufanele kwenziwe ngokunemba nangokucophelela ukuze kugwenywe noma yiziphi izinkinga ezingase zibe khona. Ukuqondanisa okufanele, ukuxhumana okuvikelekile, nokusekelwa okwanele kubalulekile ekusebenzeni kahle kwesistimu. Kubalulekile futhi ukulandela izinkombandlela zomkhiqizi kanye nezincomo zokufakwa, kufaka phakathi ukusetshenziswa kwama-sealant ahambisanayo kanye nama-adhesive.

Ukugcinwa njalo nokuhlolwa kwamavalvu okuhlola e-PVC nokufakwa kubalulekile ekuhlonzeni nasekuxazululeni noma yiziphi izinkinga ezingase zibe khona. Lokhu kuhlanganisa ukuhlola izimpawu zokuguga, ukugqwala, noma ukulimala, kanye nokuqinisekisa ukuthi amavalvu asebenza ngendlela efanele nokuthi avaleka kahle. Noma yiziphi izingxenye ezigugile noma ezilimele kufanele zishintshwe ngokushesha ukuze kuvinjelwe ukwehluleka kwesistimu nokuvuza.

Sengiphetha, umgomo we-PVC hlola ama-valve nokufakwa kusekelwe ekhonweni lokulawula ukugeleza koketshezi ohlelweni lwamapayipi. Ukuqonda ukusebenza nokukhethwa okufanele kwalezi zingxenye kubalulekile ekusebenzeni kahle nokuthembekile kokusebenza kwamapayipi, ukuchelela, kanye nezinhlelo zezimboni. Ngokunamathela ezindinganisweni zemboni kanye nezindlela ezihamba phambili, amavalvu okuhlola e-PVC kanye ne-UPVC anganikeza ukusebenza okuhlala isikhathi eside futhi anikele ekusebenzeni okuphelele kohlelo lwamapayipi.
