I-China Double Flange Butterfly Valve mveliso kunye nabavelisi

Ivalvu yeButterfly ephindwe kabini

Inkcazo emfutshane:

Iivalvu yebhabhathane ephindwe kabiniyivalvu yebhabhathane ehleliyo eqinileyo ene-integral flanges eziphoswe kuzo zombini iziphelo, ivumela uqhagamshelo oluqinileyo kwipayipi ngaphandle kwee-adaptha zeflange ezongezelelweyo. Isihlalo serabha sihlanganiswe ngokupheleleyo emzimbeni, siqinisekisa ukutywinwa okuthembekileyo kwe-bi-directional. Njengevalvu yokujika ikota, isebenza njengevalvu yokuzihlukanisa kunye nevalvu elawula ukuhamba kwamanzi kwii-engile ezahlukeneyo zokuvula. Ifanelekile kwinkonzo yokuphela komgca. Yenziwe ngokwe-API 609 / EN 593, ubuso ngobuso ngokwe-ISO 5752 / EN 558-1 Series 13, isiphelo seflange EN 1092-2 PN10/PN16/PN25 kunye ne-ANSI Class 125/150. Uluhlu lobungakanani DN50–DN1200. Umzimba kunye nediski kwi-ductile iron, i-carbon steel, i-stainless steel, okanye i-alu-bronze. Izinto zesihlalo: EPDM, NBR, FKM, i-silicone. I-Nortech ngumvelisi kunye nomthengisi weevalvu zebhabhathane zeflange ezimbini eziphambili eTshayina.

Ivalvu yeButterfly ephindwe kabini eneflange — Umboniso wentshayelelo

Yintoni iValve yeButterfly eFlange eBini?

Iivalvu yebhabhathane ephindwe kabiniyivalvu yebhabhathane ehleli phantsi eqinileyo ene-integral flanges ezidityanisiweyo kuzo zombini iziphelo, ivumela uqhagamshelo oluqinileyo ngqo kumbhobho ngaphandle kwee-adaptha ezongezelelweyo. Njengazo zonke iivalvu zebhabhathane ezihleli phantsi eziqinileyo, yivalvu ejika ikota: idiski ejikelezayo efakwe embindini womzimba isebenza njengendlela yokuvala, eqhagamshelwe kwi-actuator okanye kwisibambo nge-central shaft. Ukujikeleza okupheleleyo kwama-90-degree kuvula okanye kuvala ngokupheleleyo ivalvuinkonzo yokuzihlukanisa.

Xa idiski ingajikelezi ukuya kwikota epheleleyo, ivalvu ivuleke kancinci — ivumela ukuchanekaulawulo lokuhamba kwamanzikwii-engile ezahlukeneyo zokuvula. Isihlalo serabha sifakwe ngokupheleleyo emzimbeni, siqinisekisa ukutywinwa okuthembekileyo kwecala ngalinye kuluhlu olupheleleyo lobukhulu, kuquka nobunzimaiimeko zokusebenza nge-vacuum.

Iivalvu zebhabhathane zeNortech ezine-flange ephindwe kabini ziyilwe ngomlinganiselo omde wobuso nobuso ohambelana ne-EN 558-1 Series 13, nto leyo eyenza ukuba zifaneleke kwiintlobo ngeentlobo zezicelo ezibanzi nezinzima kubandakanya iinethiwekhi zokusasaza amanzi, izityalo zonyango lwamanzi, amadama, izityalo zamandla, kunye neenkqubo zepayipi ezinobukhulu obukhulu. Ivalvu ingasetyenziswa njengevalvu yokwahlulahlula, itephu yokukhupha amanzi ekupheleni kombhobho, okanye isixhobo sokulawula ukuhamba kwamanzi. Kwimibhobho enobukhulu obukhulu, ulungiselelo lweflange ephindwe kabini lolona khetho luqhelekileyo.

Itshati ye-CV/KV yevalvu yebhabhathane ehleliyo ehlala iqinile yohlobo lweflange ephindwe kabini iyafumaneka xa iceliwe.

Ukujongana ubuso ngobuso ixesha elide kwi-EN 558-1 Series 13— uyilo lweflange ephindwe kabini lubonelela ngoqhagamshelo oluqinileyo noluzixhasayo olufaneleke ngokukodwa kwiipayipi ezinkulu kunye nokusetyenziswa komjikelo ophezulu apho uzinzo kunye nokulungelelaniswa kweevalvu kubalulekile.
