Unokukhetha njani ivalve yebhabhathane yePVC?
Xa ukhetha ivalve yebhabhathane ye-worm ye-UPVC, kukho izinto ezininzi ekufuneka uziqwalasele ukuqinisekisa ukuba ukhetha ivalve echanekileyo yosetyenziso lwakho oluthile. Nantsi eminye imiba ephambili:
1, Ubungakanani:
Qinisekisa ubungakanani bevalve efunekayo ngokusekelwe kwisantya sokuhamba kunye nobubanzi bombhobho wenkqubo. Iisayizi zevalvu kufuneka zihambelane neziseko zombhobho ezikhoyo.
2, Amanqaku oxinzelelo kunye nobushushu:
Cinga ngoxinzelelo lokusebenza kunye nokushisa kwenkqubo ukuqinisekisa ukuba i-valve inokusingatha le miqathango ngaphandle kokunciphisa ukusebenza okanye ukhuseleko.
3, Ukuhambelana kwezinto:
I-UPVC (i-Polyvinyl Chloride engaxutywanga) iyaziwa ngokumelana neekhemikhali, kodwa kubalulekile ukuqinisekisa ukuba izinto eziphathekayo ziyahambelana nolwelo kunye neekhemikhali ezikwinkqubo yokuthintela ukubola okanye ukuthotywa.
4, Qeda uqhagamshelo:
Khetha uxhulumaniso olufanelekileyo lwesiphelo (i-flange, i-clamp, i-lug, njl.) ngokusekelwe kwiimfuno zofakelo kunye nokuhambelana neenkqubo zombhobho ezikhoyo.
5, Indlela yokuSebenza:
Kuba ukhankanye iivalvu zegiya leentshulube ngokuthe ngqo, qwalasela eyona ndlela isebenzayo ifanele iimfuno zakho zokusebenza. Iivalvu ezisebenza ngezixhobo zeentshulube zibonelela ngolawulo oluchanekileyo kwaye zinokusebenza kwiindawo ezinzima ukufikelela kuzo.
6, Umgangatho kunye neMigangatho:
Qinisekisa ukuba iivalvu ziyahlangabezana nemigangatho yoshishino kunye neziqinisekiso zomgangatho, ukusebenza kunye nokhuseleko, njenge-ISO, i-API okanye imigangatho ye-ANSI.
7, Isicelo:
Qwalasela usetyenziso oluthile kunye neempawu zolawulo lokuqukuqela ezifunekayo (on/off, throttling, etc.) ukukhetha ivalve eyifaneleyo iimfuno zakho zokusebenza.
8, abavelisi kunye nababoneleli:
Khetha umenzi othembekileyo okanye umthengisi onerekhodi yokuhambisa iivalvu ze-UPVC ezikumgangatho ophezulu kunye nenkxaso ethembekileyo yabathengi.
Ngokuqwalasela ezi zinto, unokwenza isigqibo esinolwazi xa ukhetha ivalve yebhabhathane yegiya ye-worm ye-UPVC kwisicelo sakho. Ukuba uneemfuno ezithile zobugcisa okanye ufuna uncedo, kuyacetyiswa ukuba udibane neengcali zevalvu okanye umboneleli ngesikhokelo somntu.
