1. Mawu Oyambaku Butterfly Valves
1.1. Tanthauzo ndi Ntchito Zoyambira
A valavu ya butterflyndi chipangizo chomwe chimayendetsa kayendedwe ka chitoliro. Imayendetsedwa ndi kuzungulira chimbale kotala kutembenukira. Nthawi zambiri amagwiritsidwa ntchito m'mapulogalamu omwe amatseka mwachangu.
1.2. Mbiri ya Butterfly Valves
Mavavu agulugufe amatha kutsatiridwa mpaka kumapeto kwa zaka za zana la 19. The prototype wa valavu agulugufe masiku ano anabadwa cha m'ma 20. Pambuyo pazaka zambiri zachitukuko, yakhala njira yosunthika yowongolera media m'mafakitale osiyanasiyana.
Kukula kwaukadaulo kwa mavavu agulugufe sikunayime. M'tsogolomu, ma valve a butterfly adzakhala opepuka komanso ophatikizana. Atha kugwiritsidwanso ntchito pazovuta kwambiri (monga kuthamanga kwambiri komanso kutentha kwambiri). Mwina angagwiritsidwe ntchito m'mapulogalamu atsopano m'munda wa mphamvu zongowonjezwdwa, monga mphamvu ya dzuwa, mphamvu yamphepo ndi mapulojekiti obiriwira a hydrogen.
1.3. Kugwiritsa Ntchito Mavavu a Gulugufe M'mafakitale Osiyanasiyana
1.3.1. Kusamalira Madzi ndi Kugawa
M'malo opangira madzi ndi machitidwe ogawa. Mavavu agulugufe ndi ofunikira. Amayendetsa bwino ndikupatula madzi akumwa. Kutsika kwawo kocheperako komanso kuthekera kwawo kotsekera komwe kumakhala kopindulitsa kwambiri pakuwonetsetsa kuti madzi akupezeka mosalekeza.
1.3.2. HVAC Systems
M'machitidwe otenthetsera ndi mpweya (HVAC), ma valve agulugufe amagwiritsidwa ntchito kuwongolera kayendedwe ka madzi. Kuphweka kwawo kwa makina kumawapangitsa kukhala oyenera kuwongolera machitidwe amadzi ozizira komanso otentha.
1.3.3. Zomera za Chemical ndi Petrochemical
Mavavu agulugufe omwe amagwira ntchito katatu amatha kuthana ndi mankhwala osiyanasiyana, kuphatikiza madzi owononga komanso owononga. Kukhoza kwawo kugwira ntchito pa kutentha kwakukulu ndi kupanikizika kumawapangitsa kukhala oyenera ntchito monga kukonza mankhwala, kusungirako, ndi machitidwe operekera.
1.3.4. Makampani a Mafuta ndi Gasi
Makampani amafuta ndi gasi amadalira mavavu agulugufe kuti agwiritse ntchito monga kudzipatula kwa mapaipi, kayendetsedwe ka kayendetsedwe kake, ndi matanki. Kugwirizana kwa ma valve agulugufe okhala ndi zinthu zambiri kumatsimikizira ntchito yawo yotetezeka mumakampani amafuta ndi gasi.
1.3.5. Kukonza Chakudya ndi Chakumwa
Ukhondo ndi chinthu chofunika kwambiri pokonza zakudya ndi zakumwa. Mavavu agulugufe okhala ndi mawonekedwe aukhondo komanso opukutidwa atha kugwiritsidwa ntchito kukhala aukhondo komanso kupewa kuipitsidwa pogwira zamadzimadzi monga timadziti, mkaka, ndi zakumwa. Zonse ziwiri za mphira wa wras-certified ndi zitsulo zosapanga dzimbiri za chakudya zimatha kukwaniritsa izi.
1.3.6. Kupanga Marine ndi Zombo
Mavavu agulugufe amkuwa amapangidwa kuti azigwiritsidwa ntchito m'madzi kuti aziwongolera machitidwe a ballast, madzi ozizira, ndi mizere yamafuta. Zida zolimbana ndi dzimbiri za mavavu agulugufe zimawapangitsa kukhala abwino kugwiritsidwa ntchito m'malo ovuta kwambiri am'madzi.
1.3.7. Zomera Zamagetsi
M'mafakitale amagetsi, mavavu agulugufe amagwiritsidwa ntchito m'makina ozizira, mizere ya nthunzi, ndi makina a flue gas desulfurization. Amatha kuthana ndi kuthamanga kwambiri komanso madzi otentha kwambiri.
1.3.8. Zomera Zochizira Madzi Otayira
Mavavu agulugufe ndi ofunikira pakuwongolera matope, mpweya, ndi kutuluka kwa madzi m'malo opangira madzi oyipa.
1.3.9. Makampani a Pulp ndi Paper
Makampani a zamkati ndi mapepala amapindula ndi mavavu agulugufe m'njira monga kuphika zamkati, kuthirira, komanso kubwezeretsa mankhwala. Kukana kwawo ku zamkati ndi mankhwala kumawonjezera magwiridwe antchito komanso moyo wautumiki.
