Kodi ndi malo ati omwe amagwiritsidwa ntchito kwambiri pa valavu?

Ma valve m'mafakitale osiyanasiyana amagwiritsidwa ntchito m'njira zosiyanasiyana, makamaka mu mafuta, petrochemical, mankhwala, zitsulo, mphamvu zamagetsi, kusamalira madzi, zomangamanga m'mizinda, moto, makina, malasha, chakudya ndi zina (zomwe, ogwiritsa ntchito makina ndi mankhwala pamsika wa ma valve amakhudzidwa kwambiri ndi zosowa za ma valve nazonso ndizokwera).

1, ma valve oyika mafuta
Chipinda choyeretsera mafuta. Ma valve ambiri ofunikira pamakina oyeretsera mafuta ndi ma valve a mapaipi, makamakavalavu ya chipatas, ma valve ozungulira, ma valve owunikira, ma valve oteteza, ma valve a mpira, ma valve a gulugufe, misampha. Pakati pawo, valavu ya chipata iyenera kuwerengera pafupifupi 80% ya chiwerengero chonse cha ma valve, (ma valve anali 3% mpaka 5% ya ndalama zonse zomwe zayikidwa mu chipangizocho).

2, mavavu ogwiritsira ntchito magetsi a Hydroelectric
Ntchito yomanga malo opangira magetsi ku China ikupita patsogolo kwambiri, kotero kufunika kwa ma valve akuluakulu ndi otetezeka kwambiri, ma valve ochepetsa kuthamanga, ma valve apadziko lonse, ma valve a chipata,Ma valve a gulugufe olimba,ma valve oletsa mwadzidzidzi ndi ma valve owongolera kuyenda kwa madzi, ma valve a globe ozungulira osindikizira zida.

3, mavavu ogwiritsira ntchito zitsulo
Makampani opanga zitsulo mu khalidwe la alumina amafunika makamaka kuti azitha kuwononga valavu yolimba (pakuyenda kwa mavavu a globe), kuwongolera misampha. Makampani opanga zitsulo makamaka amafuna mavavu a mpira otsekedwa ndi zitsulo, mavavu a gulugufe ndi mavavu a mpira wokhuthala, kuwala kodulidwa ndi mavavu olunjika anayi.

4, valavu yogwiritsira ntchito m'madzi
Pambuyo pa chitukuko cha migodi yamafuta m'mphepete mwa nyanja, kuchuluka kwa tsitsi lake lathyathyathya lomwe limafunika kuti ligwiritse ntchito valavu kwawonjezeka pang'onopang'ono. Mapulatifomu a m'madzi amafunika kugwiritsa ntchito mavalavu a mpira otsekedwa, mavalavu owunikira, ndi mavalavu anjira zambiri.

5, valavu yogwiritsira ntchito chakudya ndi mankhwala
Makampaniwa amafunikira makamaka ma valve a mpira osapanga dzimbiri, ma valve a mpira apulasitiki okha komanso ma valve a gulugufe. Magulu 10 omwe ali pamwambapa a ma valve, poyerekeza ndi ambiri omwe amafunidwa ndi ma valve ambiri, monga ma valve a zida, ma valve a singano, ma valve a singano, ma valve a chipata, ma valve a globe,valavu yoyezeras, ma valve a mpira, ma valve a gulugufe makamaka.

6, kumidzi, ma valve otenthetsera m'mizinda
Dongosolo lotenthetsera la mzinda, liyenera kugwiritsa ntchito ma valve ambiri a gulugufe otsekedwa ndi chitsulo, ma valve olinganiza opingasa ndi ma valve a mpira obisika mwachindunji. Chifukwa cha mtundu uwu wa valavu, kuthetsa mavuto a payipi ya longitudinal ndi transverse hydraulic, kuti akwaniritse kusunga mphamvu, kupanga kutentha koyenera.

7, mavavu ogwiritsira ntchito payipi
Mapaipi akutali makamaka a mafuta osakonzedwa, zinthu zomalizidwa ndi mapaipi achilengedwe. Ma valve ambiri amtunduwu amafunika kugwiritsidwa ntchito ndi achitsulo chopangidwa ndi ma valve atatu a mpira wodzaza ndi zitsulo, ma valve a chipata cha anti-sulfur plate, ma valve achitetezo, ndi ma valve owunikira.
