The theButterfly Valveyakagadzirwa muUnited States kuma1930s. Yakanga yakaunzwa kuJapan muma1950s uye haina kushandiswa zvakanyanya muJapan kusvika kuma1960. Izvo hazvina kuzadzikiswa munyika yangu kusvika kuma1970s. Iyo huru maficha emabhazi mandhudzi ndeyako: diki yekushandisa torque, diki yekuisa nzvimbo uye uremu hwechiedza. Kutora dn1000 semuenzaniso, iyoButterfly Valveinenge 2t, nepoGedhi Guyvendezve 3.5T. The theButterfly ValveZviri nyore kusanganisa nemidziyo yakasiyana-siyana yekutyaira uye ine yakanaka yekubvumirana uye kuvimbika. Iko kushushikana kwemavharu-akasungwa-chisimbiso butters Naizvozvo, sarudza nenzira yakakodzera zvinoenderana nemamiriro ekushanda. Ukama pakati pekuvhurwa kweiyo butterfly vharuvhu uye chiyero chinoyerera chiri mutsara mutsara. Kana ikashandiswa kudzora huwandu hwekuyerera, maitiro ayo anoyerera anoenderana chaizvo neyekuenderera mberi kwekuparadza kupopotedzana. Semuenzaniso, kana iyo vheji caliber uye fomu yepaPepa mbiri idzi dzakafanana, asi kupfeka pombi inokanganisa kwakasiyana, huwandu hwekuyerera hwevharanda huchave hwakasiyana kwazvo. Kana iyo vharuvhu iri mumamiriro ehuremu hombe yemukati, cavitation inowanzoitika kumashure kweiyo vhesi ndiro, iyo inogona kukanganisa vharuvhu. Inowanzo shandiswa kunze kwe15 °. Kana iyoButterfly ValveKuvhurwa kwepakati, chimiro chekutanga chakaumbwa nemuviri wemuvhari uye nekumberi kwemuviri webhenji ndiro butternly plate yakanangana neValve Shaft Shaft, uye nyika dzakasiyana dzinoumbwa pamativi ese maviri. Kupera kwekumberi kweiyo butterfly ndiro parutivi kunofamba munzira yekuyerera kwemvura, uye rumwe rutivi runofamba munzira yekuyerera kwemvura. Naizvozvo, muviri wemuvhari uye ndiro yekuvharidzira kune rumwe rutivi fomu yekuvhurwa-yakavezwa, uye rimwe divi rakafanana nekuvhurwa kwegomba rakaumbwa. Rutivi rwehurumende rune rutivi rwakawanda rwakanyanya kuyerera kupfuura dzimba dzekuyerera, uye kudzvanywa kwakaipa kuchawiswa pasi pevharuvhu pabendekete rutivi, uye chisimbiso cheRabha chinowanzowira pasi. Torque yekushandisa yeButterfly Valveinosiyana nekuda kwekuvhurika kwakasiyana uye iyo yekuvhura uye yekuvhara mirayiridzo yevharuvhu. Iyo torque yakagadzirwa nemusiyano uripo pakati pemvura yepamusoro uye yakadzika yemvura misoro yeiyo butterfly butterlite butter, kunyanya vharuvhu rakakura-divhiri, nekuda kwekudzika kwemvura, hakugone kufuratirwa. Mukuwedzera, iyo iyo elbow yakaiswa pane iyo inlet rutivi rwevharu, kuyerera kwevayeti kunoumbwa, uye torque ichawedzera. Kana iyo vharuvhu iri pakati pekuvhura kwepakati, iyo mechanism yekushandisa inoda kuzvivhara nekuda kwekuita kweiyo mvura yeTorque.
China inayo dzine mavhesi mazhinji endustry ngetani, asi haisiri simba revheni. Kazhinji, nyika yangu yapinda munzvimbo dzekusimba kwenyika dzenyika, asi maererano nehunhu hwechigadzirwa, nyika yangu ichiri kure nekuve simba remuviri. Iyo indasitiri ichine kuderera kwekugadzira kugadzirwa, yakaderera r & D kugona kwemavhiri kunoenderana nezvigadzirwa zvakakwirira, uye kuendesa tekinoroji muindasitiri yevalve Chokwadi hapana makambani mazhinji emagetsi anogona kupukunyuka mumusika. Nekudaro, uku kushamiswa kwakanyanya muindasitiri yeValve kuchaunza mikana mikuru, uye mhedzisiro yekuvhunduka ichaita kuti musasa ugokure kushanda zvine musoro. Nzira yekubatana kwemavharanda yakakwirira-yekupedzisira "Bumpy". Zvikamu zvekutanga zvave kupfupika izvo zvinodzora kukura kwendasitiri yenyika yangu yekugadzira nyika kusvika pakakwirira. Mukati mechirongwa chegumi nemana chechishanu, hurumende icharamba ichiwedzera nzvimbo yemidziyo yakakwira. Pano tinosarudza akati wandei zviitiko zvakakosha mu "kuronga kusingaenzaniswi" uye mumiriri vhezi dzeValve kuti dziongorore kuongororwa kwekunze kwekutsiva kwekutsiva kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekutsiva kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva kwekunze kwekutsiva kwekutsiva. Kubva pakuongororwa, zvinogona kuoneka kuti kutyisidzirwa kwekutsiva kwemavhiri mumakavha akasiyana-siyana kunosiyana-siyana, uye menduru yakakwirira inoda kukurumidza kutungamira uye yesainzi yekutumira rubatsiro rwesainzi.
Iyo indasitiri yeValve inoitira basa rakakosha sechinhu chakakosha pakubatanidza muindasitiri yekugadzira muhupfumi hwenyika. Sezvo mwero wedanho rangu renyika ivhu rekugadzira ivhu rekugadzira ichiri imwe kure kure kure neInternational Advanced Level, kiyi zhinjimavharuvhuNemaratidziro akakwirira, tembiricha yakanyanya uye yakanyanya kumanikidzwa, uye yakakwira pound level yagara ichivimba pakupinza. Semuenzaniso, iyo European Omal Brand yagara iri sarudzo huru yeiyo imba yekunyorera vhezheni. Kuti vasimudzire kunyanyogarisa kwemavhiri, mushure mekunge Dare reHurumende rikapa "pfungwa dzinoverengeka pakudzokorora kwemaindasitiri" Inotungamirwa neNational Development uye Reform Commission, iyo China Machina Indasitiri Federation uye China General Machiny Indasitiri Ashamwaridzani uye Yakagadzirirwa AvalveChirongwa chemazano emidziyo mikuru muminda yakanangana, uye yakarongedzerwa nemadhipatimendi akakodzera kazhinji. Ikozvino nzvimbo yemavharavha yakaumba kubvumirana mune indasitiri yemumba. Anoshingairira kugamuchira zviyero zvepasi rose zvekugadzirwa kwechigadzirwa; kutora zvakanakisa zvekunze zvigadzirwa zvekugadzira (zvinosanganisira matekinoroji akatorwa); Kuongororwa kwechigadzirwa uye kuongororwa kwekuita kwakanyatsoitwa zvinoenderana maererano nemitemo yenyika; tora mari yekunze yekugadzira chiitiko uye inobatanidza kukosha kune yekutsvaga nekusimudzirwa kwezvinhu zvitsva; Taura kujekesa tekinoroji yehunyanzvi uye mamiriro ekushanda ekunze-paramende vhaizvigadzirwa zvigadzirwa, etc. inzira dzekusimudzira maitiro emamiriro ekunze, kusimudzira kugadziridzwa kwezvigadzirwa zvekuvharidzira, uye ziva zvakanyatsoziva zvemavhiri. Nekuwedzera kwekumhanya kwekudzoreredza muindasitiri yeValve, indasitiri yemangwana ichave mukwikwidzi pakati pevhuviri chigadzirwa mhando uye kuchengetedzwa uye zvigadzirwa zvechengetedzo. Zvigadzirwa zvichakudziridza munzira yehunyanzvi hombe, paramende yakakwirira, kurwisa kwakasimba kwakasimba, uye hupenyu hwakareba.
