Incazelo Yomkhiqizo

I-JIS F7471 Bronze swing check valve iyingxube yethusi engu-5K ethobelana Namazinga Emboni Yase-Japan (JIS).

Yethula:

I-JIS F7471 I-valve yokuhlola i-Bronze swing iyi-valve yohlobo lokushwiba elungele ukulawula uketshezi ezinhlelweni zamapayipi. Ingasetshenziselwa ukuvimbela ukubuyela emuva nokulawula ukugeleza koketshezi.

Inzuzo:

Ukumelana nokugqwala: I-Copper alloy material inokumelana nokugqwala okuhle kakhulu futhi ilungele izinhlobonhlobo zemidiya nezindawo zokusebenza.
Ukuthembeka: Idizayini yokuphakamisa iqinisekisa ukuthi i-valve ingakwazi ukubona ngokuthembekile imisebenzi yokuhlola nokuhlukanisa futhi iqinisekise ukusebenza okuzinzile kwesistimu yamapayipi.
Ukulungiswa okulula: Idizayini yekhava ye-valve ehlanganisiwe yenza ukugcinwa nokuhlola kube lula futhi kunganciphisa isikhathi sokuphumula.

Ukusetshenziswa:

I-JIS F7471 Ivalvu yokuhlola i-Bronze swing (uhlobo lwebhonethi yenyunyana) isetshenziswa kakhulu ukulawula ukugeleza koketshezi ohlelweni lwamapayipi, ukuvimbela ukugeleza emuva nokulawula ukugeleza. Ifanele izicelo ezinhlelweni zokuhlanza amanzi, izinhlelo zokuhlinzeka ngamanzi, izinhlelo zamanzi olwandle, ukwakhiwa kwemikhumbi kanye nobunjiniyela basolwandle.

Izici

Uhlolojikelele Lomkhiqizo

I-Copper alloy material: Umzimba we-valve kanye nesembozo se-valve zenziwe nge-alloy yethusi engagqwali, enokuqina okuhle kakhulu nokumelana nokugqwala.
Idizayini ye-Swing: I-disc ye-valve yamukela umklamo wokushwibeka, ongafinyelela ukulawula okunembile koketshezi futhi uvimbele ukugeleza emuva.
Izinga lokucindezela elijwayelekile elingu-5K: Ithobelana neleveli yokucindezela evamile engu-5K futhi ifanele amasistimu okucindezela okuphakathi nendawo naphansi.
Idizayini yekhava yenyunyana: Idizayini yekhava yenyunyana isiza ukugcinwa nokuhlolwa.

I-wireframe yomkhiqizo

Ama-valve okuhlola awasebenzi ngokusekelwe kumfutho ohlukile wodwa. Ukube bekunjalo, ukugeleza bekuyokwanela ukuvula i-valve. Ngakho-ke, ukucindezela okuncane okuncane kuyadingeka ukuze uvule i-valve yokuhlola. Lokhu kwaziwa ngokuthi yi-cracking pressure. Ukucindezela kokuqhekeka kwe-valve yokuhlola ingcindezi encane ebekiwe edingekayo ukuze uvule i-valve yokuhlola, okwanele ukuvumela ukugeleza okubonakalayo.
