Thebutterfly valveyakagadzirwa muUnited States kuma1930s. Yakaunzwa kuJapan muma1950 uye haina kushandiswa zvakanyanya muJapan kusvika kuma1960. Yakanga isina kufarirwa munyika yangu kusvika kuma1970. Izvo zvakakosha zve butterfly mavharuvhu ndeizvi: diki yekushandisa torque, diki yekuisa nzvimbo uye huremu huremu. Kutora DN1000 semuenzaniso, iyobutterfly valveingangoita 2T, nepo iyogedhi vharafuinenge 3.5T. Thebutterfly valveiri nyore kusanganisa neakasiyana dhiraivha madivayiri uye ine yakanaka kusimba uye kuvimbika. Kukanganisa kwerubha-yakavharwa butterfly mavharuvhu ndeyekuti kana ichishandiswa kupuruzira, cavitation ichaitika nekuda kwekushandisa zvisina kunaka, zvichiita kuti chigaro cherubha chibvise uye kukuvara. Naizvozvo, kuti ungasarudza sei nemazvo zvinoenderana nemamiriro ekushanda. Hukama huri pakati pekuvhurwa kwevharuvhu yeshavishavi uye mwero wekuyerera unongoenderana. Kana iyo yakashandiswa kudzora kuyerera kwayo, maitiro ayo ekuyerera anoenderanawo zvakanyanya nekuyerera kwepiping. Semuenzaniso, kana iyo caliber yevharuvhu uye chimiro chemapaipi maviri ese akafanana, asi pombi yekurasikirwa kwecoefficient yakasiyana, kuyerera kwevhavha kuchave kwakasiyana kwazvo. Kana vharuvhu iri mumamiriro ekukura kukuru kweamplitude, cavitation inowanzoitika kuseri kweplate yevhavha, iyo inogona kukuvadza valve. Inowanzo shandiswa kunze kwe15 °. Apo iyobutterfly valveiri pakati pekuvhura, chimiro chekuvhura chinoumbwa nemuviri wevharuvhu uye kumucheto kwemberi kweshavishavi ndiro yakatarisana nevharuvhu shaft, uye nyika dzakasiyana dzinoumbwa pamativi ese. Kunoperera ndiro yeshavishavi kune rimwe divi kunofamba ichienda kwainoyerera mvura, uye rimwe divi rinofamba richienda kwainoyerera mvura. Naizvozvo, muviri wevharuvhu neplate yevharuvhu kune rimwe divi zvinogadzira kuvhurika kwakafanana nemhuno, uye rimwe divi rakafanana nekuvhurika kwegomba. Rutivi rwenozzle rune kukurumidza kuyerera kweyero kupfuura iyo throttle side, uye kudzvanya kwakashata kunogadzirwa pasi pevharuvhu padivi re throttle, uye chisimbiso cherabha chinowanzodonha. Iyo yekushandisa torque yebutterfly valveinosiyana nekuda kwekuvhura kwakasiyana uye nzira yekuvhura nekuvhara yevhavha. Iyo torque inogadzirwa nemusiyano pakati pemisoro yepamusoro uye yepasi yemvura yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,kunyanya dhayamita hombe, nekuda kwekudzika kwemvura, haigone kuregererwa. Uye zvakare, kana gokora rakaiswa padivi rekupinza revhavha, kuyerera kwebias kunoumbwa, uye torque inowedzera. Kana vharuvhu iri pakati pekuvhura, iyo inoshanda sisitimu inoda kuvharika yega nekuda kwekuita kweiyo mvura inoyerera torque.
China ine akawanda mavharuvhu indasitiri cheni, asi haisi simba revharuvhu. Kazhinji, nyika yangu yakapinda muzvikamu zvemasimba evharuvhu enyika, asi maererano nemhando yechigadzirwa, nyika yangu ichiri kure kubva pakuva simba revharuvhu. Indasitiri ichine yakaderera kugadzirwa, yakaderera R&D kugona kwemavharuvhu anoenderana-yekupedzisira zvigadzirwa, uye yakaderera yekugadzira tekinoroji muindasitiri yevharuvhu, uye kushomeka kwekutengeserana kwekunze uye kunze kwenyika kuri kuramba kuchiwedzera. Iko hakuna makambani mazhinji evharuvhu anogona kunyatso kurarama mumusika. Nekudaro, uku kuvhunduka kukuru muindasitiri yevharuvhu kuchaunza mikana mikuru, uye mhedzisiro yekuvhunduka ichaita kuti musika ushande zvine musoro. Nzira yekuenda kunzvimbo yemavharuvhu epamusoro-soro yakanyanya "bumpy". Zvikamu zvekutanga zvave kushomeka kunoganhurira kusimukira kweindasitiri yekugadzira yenyika yangu kusvika kumagumo. Munguva yeChirongwa cheMakore Mashanu chegumi nembiri, hurumende icharamba ichiwedzera kuwanikwa kwezvikamu zvepamusoro zvemidziyo. Pano tinosarudza zvakati wandei zvakakosha mu "Implementation Plan" uye anomiririra mavharuvhu maindasitiri ekugoneka kuongororwa kweiyo inotsiva inotsiva. Kubva pakuongorora, zvinogona kuonekwa kuti kukwanisa kwekutumira kune dzimwe nyika kutsiva mavharuvhu mune akasiyana-siyana maindasitiri anosiyana zvakanyanya, uye mavharuvhu ekupedzisira anoda nekukurumidza nhungamiro yemitemo uye rutsigiro rwekutsvagisa kwesainzi.
Indasitiri yevharuvhu inoita basa rakakosha sechinhu chakakosha muindasitiri yekugadzira michina mukusimudzira hupfumi hwenyika. Sezvo nhanho yeindasitiri yekugadzira mavharuvhu munyika yangu ichiri chinhambwe kubva padanho repamusoro repasi rose, makiyi mazhinjimavharuvhuine yakakwirira paramita, tembiricha yakakwira uye yakanyanya kudzvanywa, uye yakakwirira pondo level yagara ichivimba nekunze. Semuenzaniso, iyo yeEuropean OMAL mhando yagara iri sarudzo huru yeindasitiri yekushandiswa kwevharuvhu. Kuti vasimudzire kugariswa kwemavharuvhu, mushure mekunge State Council yaburitsa "Maonero akati wandei pamusoro peKukurumidzira Kudzoreredzwa kweEquipment Manufacturing Indasitiri", madhipatimendi ehurumende akakodzera akaita nhevedzano yekutumira kukuru maererano nezvinodiwa nehurumende kuti ive nenzvimbo. midziyo mikuru. Ichitungamirwa neNational Development and Reform Commission, China Machinery Industry Federation neChina General Machinery Industry Association vakaisa nekugadziravharafuchirongwa chenzvimbo yemidziyo mikuru muminda ine hukama, uye vakaronga nemadhipatimendi akakodzera kakawanda. Ikozvino kuiswa kwemavharuvhu kwakagadzira kubvumirana muindasitiri yevharuvhu yemumba. Shingairira kutora zviyero zvepasi rose zvekugadzirwa kwechigadzirwa; tora kunze kwenyika dzakanakisa dhizaini zvimiro (kusanganisira patented tekinoroji); Kuongororwa kwechigadzirwa uye kuongororwa kwekuita kunoitwa zvakanyanya maererano nemaitiro epasirese; tora ruzivo rwekune dzimwe nyika kugadzirwa kwemaitiro uye batanidza kukosha kutsvagurudzo uye kusimudzirwa kwezvinhu zvitsva; kujekesa maitiro eunyanzvi uye mamiriro ekushanda ezvigadzirwa zvevharuvhu zvakatengeswa kunze kwenyika, nezvimwewo inzira dzekukurumidzira nzira yekugara, kukurudzira kuenderera mberi kwekuvandudzwa kwezvigadzirwa zvevharuvhu, uye kunyatsoona kuiswa kwevharuvhu. Nekuwedzera kwekumhanya kwekugadzirisazve muindasitiri yevharuvhu, indasitiri yeramangwana ichave makwikwi pakati pemhando yechigadzirwa chevharuvhu uye chengetedzo uye zvigadzirwa zvemhando. Zvigadzirwa zvinokura munzira yehunyanzvi hwepamusoro, yakakwirira paramita, yakasimba corrosion kuramba, uye hupenyu hurefu. Chete kuburikidza nekuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji, kuvandudzwa kwezvigadzirwa zvitsva, uye shanduko yetekinoroji inogona kuvandudzwa zvishoma nezvishoma kuti isangane nemidziyo yemumba inofananidzwa uye kunyatsoona kuiswa kwemavharuvhu. Pasi penzvimbo yakakura yekudiwa, indasitiri yekugadzira mavharuvhu yenyika yangu icharatidza zvirinani tarisiro yebudiriro.
