I-Butterfly Valve
0102030405
I-Eccentric Butterfly Valve UPVC CPVC Worm Gear Type
Izici Zomkhiqizo
1.Small switch torque.
2.Izingxenye ezishintshwayo , ezihlangene futhi ziyonga.
3. Impahla i-nano-modified ithuthukisa ukumelana nokucindezela kanye nokumelana nomthelela womkhiqizo.
I-4.Thickned valve body tor yokumelana nokucindezelwa okuphezulu.
Ukuhlolwa kwengcindezi engu-5.100% ngaphambi kokubeletha.
I-6, Izingxenye zomzimba nezokuvala ziphathwa ngokukhethekile ukuze zisebenze kangcono.
Ungakhetha kanjani i-valve ye-butterfly esebenza ngegiya le-PVC?
Lapho ukhetha i-UPVC worm gear butterfly valve, kunezici ezimbalwa okufanele uzicabangele ukuze uqiniseke ukuthi ukhetha ivalvu efanele yohlelo lwakho lokusebenza oluthile. Nazi ezinye izinto ezibalulekile ezicatshangelwayo:
1, usayizi:
Nquma usayizi we-valve edingekayo ngokusekelwe kuzinga lokugeleza kanye nobubanzi bepayipi lohlelo. Amasayizi amavalvu kufanele ahambisane nengqalasizinda yamapayipi ekhona.
2, Izilinganiso Zengcindezi Nezinga Lokushisa:
Cabangela ingcindezi yokusebenza kanye nokushisa kwesistimu ukuze uqinisekise ukuthi i-valve ingakwazi ukusingatha lezi zimo ngaphandle kokuyekethisa ukusebenza noma ukuphepha.
3, Ukuhambisana Kwezinto:
I-UPVC (Unplasticized Polyvinyl Chloride) yaziwa ngokumelana namakhemikhali, kodwa kubalulekile ukuqinisekisa ukuthi impahla iyahambisana noketshezi namakhemikhali ohlelweni ukuze kuvinjelwe ukugqwala noma ukuwohloka.
4, Qeda uxhumano:
Khetha uxhumano olufanele ekugcineni (i-flange, i-clamp, i-lug, njll.) ngokusekelwe ezidingweni zokufaka nokuhambisana namasistimu amapayipi akhona.
5, Indlela Yokwenza:
Njengoba usho ama-valve aqhutshwa ngegiya lezikelemu ngokuqondile, cabanga indlela yokuqalisa evumelana nezidingo zakho zokusebenza. Amavalvu asebenza ngegiya lezikelemu ahlinzeka ngokulawula okunembile futhi angasebenza ezindaweni okunzima ukufinyelela kuzo.
6, Ikhwalithi Namazinga:
Qinisekisa ukuthi ama-valve ahlangabezana namazinga embonini nezitifiketi zekhwalithi, ukusebenza nokuphepha, okufana namazinga e-ISO, i-API noma i-ANSI.
7, Isicelo:
Cabangela uhlelo oluthile kanye nezici zokulawula ukugeleza ezidingekayo (ukuvula/ukuvala, ukunyakazisa, njll.) ukuze ukhethe ivalvu evumelana kangcono nezidingo zakho zokusebenza.
8, Abakhi kanye Nabahlinzeki:
Khetha umkhiqizi noma umphakeli onerekhodi elihle lokuletha amavalvu ekhwalithi ephezulu we-UPVC kanye nokwesekwa kwamakhasimende okuthembekile.
Ngokucabangela lezi zici, ungenza isinqumo unolwazi lapho ukhetha i-UPVC worm gear butterfly valve ohlelweni lwakho lokusebenza. Uma unezidingo ezithile zobuchwepheshe noma udinga usizo, kunconywa ukuthi uxhumane nochwepheshe be-valve noma umhlinzeki ukuze uthole isiqondiso esiqondene nawe.
