ISIHLALO SEMETALI (EFORGED) IBHOLA VALVE
Uhlolojikelele Lomkhiqizo
I-Forged steel flange yohlobo lwe-high pressure ibhola i-valve yokuvala izingxenye zebhola ezungeze umugqa omaphakathi womzimba we-valve ukuze ujikeleze uvule futhi uvale i-valve, uphawu lufakwe esihlalweni se-valve yensimbi engagqwali, isihlalo se-valve yensimbi sinikezwa isiphethu. , lapho indawo yokuvala igqoka noma isha, ngaphansi kwesenzo sentwasahlobo ukusunduza isihlalo se-valve kanye nebhola ukwenza uphawu lwensimbi. Bonisa umsebenzi oyingqayizivele wokukhipha ukucindezela okuzenzakalelayo, lapho i-valve lumen ingcindezi ephakathi nendawo ngaphezu kwamandla entwasahlobo angaphambi kokuqina, isihlalo se-valve yokuphuma sibuyele emuva siphume endaweni, sifinyelele umphumela wokusiza othomathikhi, ngemuva kokusetha kabusha i-othomathikhi ye-valve esihlalweni, futhi sisebenza emanzini, i-solvent, i-asidi negesi, njengendawo yokusebenza evamile, kodwa futhi ifanele izimo zokusebenza zemidiya. , njenge-oxygen, i-hydrogen peroxide, i-methane ne-ethylene, isetshenziswe kahle ezimbonini ezihlukahlukene.
Izici zesakhiwo somkhiqizo:
1. Zonke izingxenye zalo mkhiqizo ziyi-forging.
2, ukusetshenziswa kwesiqu se-valve esibekwe phansi, setha isakhiwo sokuvala esihlanekezelwe, ukuqinisekisa ukuthi indawo yokupakisha ivalwa ngokuthembekile futhi ivimbele ukuphuma kwesiqu.
3. Yamukela isihlalo sevalvu efakiwe.Indandatho ye-O isethwe ngemuva kwesihlalo sevalvu ukuze kuqinisekiswe ukuthi okuphakathi akuvuzi.
