Incazelo emfushane:

Iivalvu yebhabhathane ephindwe kabiliiyivalvu yebhabhathane ehlala kahle ehlala phansi enama-flange ahlanganisiwe afakwe kuzo zombili izinhlangothi, evumela ukuxhumana okuqondile kwebhawodi epayipini ngaphandle kwama-adaptha e-flange engeziwe. Isihlalo serabha sihlanganiswe ngokuphelele emzimbeni, siqinisekisa ukuvalwa okuthembekile okuqondiswayo okubili. Njengevalvu yokujika ngekota, isebenza njengevalvu yokuzihlukanisa kanye nevalvu elawula ukugeleza kwama-engeli ahlukahlukene okuvula. Ifanelekela isevisi yokuphela komugqa. Yenziwe ngokwe-API 609 / EN 593, ubuso nobuso ngokwe-ISO 5752 / EN 558-1 Series 13, i-flange end EN 1092-2 PN10/PN16/PN25 kanye ne-ANSI Class 125/150. Ububanzi bosayizi DN50–DN1200. Umzimba kanye nediski ngensimbi ethambile, insimbi yekhabhoni, insimbi engagqwali, noma ithusi le-alu. Izinto zesihlalo: EPDM, NBR, FKM, i-silicone. I-Nortech ingumkhiqizi nomhlinzeki we-flange yebhabhathane ephindwe kabili ehamba phambili eShayina.

I-Double Flange Butterfly Valve — Ukubuka Ngaphambili Kwesingeniso

Iyini i-Double Flange Butterfly Valve?

Iivalvu yebhabhathane ephindwe kabiliiyivalvu yebhabhathane ehlala iqinile enama-flange ahlanganisiwe abekwe kuzo zombili izinhlangothi, okuvumela ukuxhumana okuqondile ngebhawodi epayipini ngaphandle kwama-adaptha engeziwe. Njengawo wonke amavalvu ebhabhathane ahlala iqinile, iyivalvu yokujika ngekota: idiski eyindilinga efakwe maphakathi nomzimba isebenza njengendlela yokuvala, exhunywe ku-actuator noma isibambo ngeshafti ephakathi. Ukujikeleza okuphelele kwama-degree angu-90 kuvula noma kuvala ivalvu ngokugcweleisevisi yokuzihlukanisa.

Uma idiski ingajikelezi ibe yikota ephelele, ivalvu ivulekile kancane — ivumela ukucacaukulawulwa kokugelezangama-engeli ahlukahlukene okuvula. Isihlalo serabha sivikelwe ngokuphelele emzimbeni, okuqinisekisa ukuvalwa okuthembekile okuqondiswa kabili kulo lonke uhla losayizi, okuhlanganisa nokufuna usizo.izimo zokusebenza ze-vacuum.

Amavalvu e-Nortech double flange butterfly aklanywe ngosayizi omude obhekene ubuso nobuso ohambisana ne-EN 558-1 Series 13, okwenza afaneleke ezinhlotsheni eziningi zezicelo ezijwayelekile nezinzima okuhlanganisa amanethiwekhi okusabalalisa amanzi, izitshalo zokuhlanza amanzi, amadamu, izitshalo zikagesi, kanye nezinhlelo zamapayipi amakhulu. Ivalvu ingasetshenziswa njengevalvu yokuhlukanisa, impompi yokukhipha amanzi ekugcineni kwepayipi, noma idivayisi yokulawula ukugeleza kwamanzi. Kumapayipi amakhulu, ukucushwa kweflange kabili kuyisinqumo esijwayelekile.

Ishadi le-CV/KV lohlobo lwe-reliable seated butterfly valve double flange liyatholakala uma ucela.

Ukubonana ubuso nobuso isikhathi eside ne-EN 558-1 Series 13— ukwakheka kwe-flange ephindwe kabili kunikeza uxhumano oluqinile, oluzisekelayo olufanelekela kakhulu amapayipi amakhulu kanye nezinhlelo zokusebenza zomjikelezo ophezulu lapho ukuzinza nokuqondanisa kwama-valve kubalulekile khona.

Ukwakhiwa okufushane — isisindo esincane, indawo yokugcina encane kanye nendawo yokufaka

Umgodi ophakathi, ukuvalwa okuqinile kwebhamuza okungu-100%, noma yikuphi ukufakwa

I-ISO 5211 top flange — ukwenza ngokuzenzakalelayo okulula kanye nokulungiswa kabusha kwe-actuator

Umzimba ogcwele imbobo — ukumelana nokugeleza okuphansi

Indlela yokugeleza engenamigoqo — kulula ukuyihlanza nokuyibulala amagciwane, ifanele amanzi aphuzwayo

Umzimba ogcwele irabha — uketshezi alukaze luthinte umzimba wensimbi

Umklamo wediski ongenaphini — ususa izindlela zokuvuza kudiski

I-torque yokusebenza ephansi — ukukhetha i-actuator engabizi kakhulu

Amabheringi afakwe i-PTFE — awadingi ukulungiswa, akukho ukuthambisa okudingekayo

Isihlalo serabha esiboshwe nge-vulcanized emzimbeni — ukuvalwa okuzinzile, okufanele ukusetshenziswa kwe-vacuum kanye nensizakalo yokuphela komugqa
