Onani Chithunzi Chachikulu
Valve ndi imodzi mwazinthu zofunika kwambiri pamagetsi owongolera madzimadzi.Pakali pano, ntchito yaikulu ya valavu monga mafuta ndi gasi, mphamvu, uinjiniya mankhwala, madzi ndi zimbudzi mankhwala, kupanga mapepala ndi zitsulo.Mwa izo, mafuta & gasi, mphamvu ndi mankhwala ndi ntchito zofunika kwambiri za valve.Malinga ndi ulosi wochokera kwa McIlvaine, wolosera zamsika, kufunikira kwa valve ya mafakitale kudzafika madola mabiliyoni a 100. Kufuna kwa magetsi m'mayiko omwe akutukuka kumene ndi chinthu chachikulu cholimbikitsa msika wa valve wa mafakitale kuti ukhalepo.Akuti kuyambira 2015 mpaka 2017, kukula kwa msika wa ma valve a mafakitale kudzakhalabe pafupifupi 7%, kukulira kwambiri kuposa kukula kwa mafakitale apadziko lonse lapansi.
Vavu ndi gawo lowongolera pamakina opatsira madzimadzi, okhala ndi ntchito zodula, kusintha, kupatutsa mitsinje, kupewera kolowera, kukhazikika kwamagetsi, shunt kapena kusefukira ndi decompression.Vavu amagawidwa kukhala valavu yowongolera mafakitale ndi valavu wamba.Vavu ya mafakitale imagwiritsidwa ntchito poyang'anira kutuluka kwa media, kuthamanga, kutentha, siteshoni yamadzimadzi ndi zina zamakono.Kutengera ndi miyezo yosiyana, valavu yamakampani imatha kugawidwa m'mitundu yosiyanasiyana.Kwa mitundu yamalamulo, valavu imagawidwa kukhala malamulo, kudula, kuwongolera ndi kudula;ponena za zipangizo za valve, valve imagawidwa muzitsulo, zopanda zitsulo ndi zitsulo;kutengera njira zoyendetsera, valavu ya mafakitale imagawidwa mumtundu wamagetsi, mtundu wa pneumatic, mtundu wa hydraulic ndi mtundu wamanja;kutengera kutentha, valavu imayikidwa mu valavu ya ultralow kutentha, valavu yotsika kutentha, valavu yotentha, kutentha kwapakati ndi kutentha kwapamwamba ndi valavu imatha kugawidwa mu vacuum valve, valve low pressure valve, medium pressure valve, valve high pressure ndi ultra. valavu yothamanga kwambiri.
Makampani opanga ma valve aku China adachokera ku 1960's.Chaka cha 1980 chisanafike, China ikanatha kupanga magulu opitilira 600 ndi miyeso ya 2,700 yazinthu zamavavu, kusowa luso lopanga valavu yokhala ndi magawo apamwamba komanso luso lapamwamba.Kukwaniritsa kufunikira kwa ma valve okhala ndi magawo apamwamba komanso luso lapamwamba lomwe limayambitsidwa ndi mafakitale ndi ulimi ku China zomwe zikukula kwambiri, kuyambira m'ma 1980.China idayamba kugwiritsa ntchito lingaliro lophatikiza chitukuko chodziyimira pawokha ndikuyambitsa ukadaulo kupanga matekinoloje a valve.Mabizinesi ena ofunikira amakulitsa kafukufuku waukadaulo ndi chitukuko, kukweza kukwera kwaukadaulo wolowetsa ma valve.Pakali pano, China yapanga kale chipata valavu, valavu padziko lonse, valavu throttle, valavu mpira, valavu butterfly, diaphragm vale, pulagi valavu, valavu cheke, valavu chitetezo, valavu kuchepetsa, valavu kuda ndi valavu zina, kuphatikizapo magulu 12, oposa 3,000 zitsanzo ndi miyeso 40,000.
Malinga ndi ma statics a Valve World, kufunikira kwa msika wapadziko lonse wa valve yamafakitale kumakhala ndi kubowola, mayendedwe ndi kupondaponda.Mafuta ndi gasi ndiwo ali ndi gawo lalikulu kwambiri, kufika pa 37.40%.Kufunika kwa uinjiniya wa mphamvu ndi mankhwala kumatsatira, motsatana ndi 21.30% ndi 11.50% ya msika wapadziko lonse wama valve ofunikira.Kufunika kwa msika muzinthu zitatu zoyambirira kumawerengera 70.20% ya kuchuluka kwa msika.Ku China, uinjiniya wamankhwala, mphamvu ndi mafuta & gasi ndiwonso msika waukulu wogulitsa ma valve.Kufunika kwa vavu motsatana kumawerengera 25.70%, 20.10% ndi 14.70% yazofunikira zonse.Kufunika kwa ndalama kumawerengera 60.50% ya kuchuluka kwa ma valve ofunikira.
Pankhani ya kufunikira kwa msika, kufunikira kwa ma valve m'malo osungira madzi ndi hydropower, magetsi a nyukiliya ndi gasi wamafuta kudzakhalabe ndi machitidwe amphamvu mtsogolomo.
Posungira madzi ndi mphamvu ya hydropower, njira yoperekedwa ndi General Office of the State Council ikuti pofika 2020, mphamvu yamagetsi wamba iyenera kufika pafupifupi ma kilowatts 350 miliyoni.Kukula kwa mphamvu ya hydropower kudzachititsa kufunikira kwakukulu kwa ma valve.Kukula kosalekeza kwa ndalama zopangira magetsi opangira madzi kudzalimbikitsa chitukuko cha valve yamakampani.
