I-Flanged Gate Valve

Leli yivalvu yesango lesakhiwo esinezingxenyana ezimbili, evame ukusetshenziswa kumapayipi okudonsa amanzi, indle noma izinto eziqukethe izinhlayiya. Isakhiwo siqondile, asinazo izingxenye eziyinkimbinkimbi. Umsebenzi waso oyinhloko ukuhlukanisa ipayipi.

Umzimba wevalvu uphonswe wonke, unezingcezu kuzo zombili izinhlangothi. Ngesikhathi sokufakwa, uxhunywe ngqo ku-flange yepayipi, ngamandla afanayo kuma-bolts, futhi akukho ukwesekwa okwengeziwe okudingekayo. Uma kuqhathaniswa nesakhiwo esingcezu, uhlobo lwe-flange lunokuqina okungcono kumadayamitha amakhulu.

Ipuleti lesango liyipuleti lensimbi engagqwali elenziwe ngomshini elihamba phezulu naphansi eceleni komsele wangaphakathi womzimba wevalvu. Uma livaliwe, ipuleti lesango licindezela ebusweni bokuvala. Uma kwenzeka inani elincane lemicu noma amadiphozithi, ngokuvamile lingasika, kodwa alifanele ukusetshenziswa kwe-throttling.

Ingxenye yokupakisha yenziwe ngesakhiwo sesembozo sokucindezela. Uma kwenzeka ukuvuza, ingaphathwa ngokuqinisa noma ukufaka okunye esikhundleni sokupakisha. Isiqu sevalvu siyadalulwa, siqhutshwa yisondo lesandla, futhi isimo sokuvula nokuvala siyaqondakala. Uma kudingeka ukulawula okuzenzakalelayo, ingashintshwa ibe yi-actuator yomoya noma kagesi, futhi isakhiwo somzimba wevalvu asidingi ukulungiswa.

- Ububanzi: DN50–DN800

- Ikilasi lokucindezela: PN10 / PN16 / Ikilasi 150

- Umzimba we-valve: Insimbi ephothiweyo / Insimbi ye-graphite ye-spheroidal / Insimbi ye-carbon / Insimbi engagqwali

- Ipuleti lesango: 304 / 316 / 316L

- Ukuvala: EPDM / NBR / PTFE / Insimbi

Lolu hlobo lwevalvu lusetshenziswa kakhulu ezimweni ezivulekile noma ezivalwe ngokuphelele. Akukhuthazwa ukuyisebenzisa ingxenye isikhathi eside. Ngesikhathi sokufakwa, qiniseka ukuthi ama-flange ahambisana ukuze ugweme ukusonteka komzimba wevalvu futhi kuthinte uphawu.
