Nka valve ikoreshwa cyane, umupira wumupira nubwoko bwinshi bwa valve.Ubwoko butandukanye bwujuje ibyifuzo byumukoresha mubihe bitandukanye, ibihe bitandukanye byubushyuhe hamwe nibisabwa bitandukanye mubikorwa nyirizina.Ibikurikira byerekana ibiranga imipira myinshi isanzwe yumupira nkumupira wamaguru ureremba, imipira ihamye yumupira, igice cyumupira wumupira wa eccentric, imipira yumupira wa V hamwe numupira wumurongo wa fluor.
Ukurikije imiterere n'imikorere, irashobora kugabanywamo:
1. Hariho ubwoko bwinshi bwimipira.Nibihe imipira ireremba: imipira ireremba ikoreshwa nkikidodo kandi umupira ureremba.Ikoresha umuvuduko wikigereranyo kugirango usunike umupira kugirango wimure intera kandi unyunyuze intebe ya valve ya elastike kugirango ugere ku kashe.Ubu bwoko bwa valve ireremba ifite ubunini bunini bwo gufungura kandi bukwiriye gusa imiyoboro nibikoresho bifite kalibiri ya DN “200 hamwe nigitutu cya PN“ 100.Niba diameter yumupira ari nini cyane, izunama umubiri wa valve ikananirwa munsi yigitutu cyikigereranyo;niba umuvuduko mwinshi cyane, umupira wumupira uzawunyunyuza kandi byoroshye kandi intebe ya valve ya elastike izahinduka burundu, bishobora kwangiza kashe kandi bikagira ingaruka kumupira.ubuzima.
2. Umupira uhagaze neza ushyirwaho nibiti bibiri byo hejuru no hepfo.Intebe ya valve ifite isoko yamababi cyangwa isoko ya silindrike.Iyo ifite ibikoresho, isoko yintebe ya valve irahagarikwa kugirango habeho imbaraga zabanje gukomera kugirango ugere kashe yambere ya valve.Umuvuduko usunika valve mugihe cyo gukoresha.Intebe yimukira mumupira kugirango igere kashe.Kuberako umupira utimuka, byitwa umupira uhamye.Ubu bwoko bwo gukosora bwizewe cyane kuruta kureremba umupira wamaguru kubera kashe yawo.Irashobora gukoreshwa murwego rwagutse, ntabwo ikoreshwa gusa kumuvuduko muke muto-diametre, ariko kandi no kumuvuduko mwinshi-diameter.Ariko imiterere yacyo iragoye cyane
, Igiciro cyigiciro ni kinini, mugihe uhisemo, ugomba guhitamo ukurikije ibikenewe nyabyo.
3. Umuyoboro wa Eccentric hemispherical valve.Ubu bwoko bwa ball valve ifata imiterere ya eccentric.Ihame ryimiterere ni kimwe nkiy'ibice byinshi bitatu bya eccentric bigoye-bifunze ikinyugunyugu.Intebe ya valve numupira ntibambara kandi bifite imikorere ikomeye yo gufunga.Umupira ni 1/4 gusa cyumupira usanzwe.Ifite ubuso bugoramye, uburemere bworoshye nigiciro gito ugereranije.Ibi bifite ingaruka zo kogosha kandi birashobora gukoreshwa mumuyoboro uciriritse urimo fibre ndende nta jaming.
4. Ikibumbano cyumupira wumuriro wumuriro ni kimwe kugeza kuri bibiri bisobanutse kurenza umupira rusange wa flange.Ifata umubiri wuzuye wa valve hamwe nu ruhande rwashushanyijeho umupira.Ikoti ry'icyuma risudira hagati ya flanges yagutse hanze yumubiri wa valve.Byitwa kandi jacket yumupira.Isohora rya jacketi ryashyizwe kumpande zombi zumubiri wa valve, zishobora guhindurwamo amavuta cyangwa gaze zishyushye kugirango wirinde gukomera cyangwa korohereza ubushyuhe bwicyumba.Imipira yumuriro wumuriro ikoreshwa cyane cyane mumiyoboro nibikoresho byoroshye korohereza kandi bisaba kubika ubushyuhe muri peteroli, imiti, metallurgiki, na farumasi.
5. Umupira wumupira wa V umeze nkumupira wumupira.Umwobo utambuka wumupira uratandukanye cyane no kugororoka unyuze mu mwobo wumupira usanzwe.Umupira ufite imiterere ya V kandi mubisanzwe ufata imiterere ihamye hamwe nibiti bibiri byo hejuru no hepfo.
6. Umuyoboro wumurongo wa florine ukunze gukoreshwa mubushyuhe buke hamwe numuyoboro ukomeye wibikoresho byangirika.Ubu bwoko bwumupira wumurongo urimo plastiki yubuhanga idashobora kwangirika nka PFA cyangwa FEP mubice byose byumuyoboro utemba uhura nuburyo.Irashobora gusimbuza ibyuma bihenze bidafite ingese na Hastelloy mugihe cyo kutarenza ubushyuhe bwa serivisi ya reberi ya fluor mumuyoboro muke., Monel alloy, No 20 alloy, ikemura ikibazo cyo gutwara itangazamakuru ryangirika cyane mumiyoboro ya peteroli na chimique

Nortech nimwe mubakora inganda zikora inganda zikomeye mubushinwa hamwe nicyemezo cyiza ISO9001.
