Kuvandudzwa kwevharuvhu yekudzora kubva pakutanga kwezana ramakore rechi20 kwave makore makumi masere enhoroondo yekudzora vharafu nekukurumidza kubvisa kupisa kunowanzo kutadza kushanu. kudzora zvigadzirwa zvevharuvhu, mavharuvhu anozvimiririra uye anomira, nezvimwewo, kudzora vharafu uye kudzora nzira yekuvandudza mavharuvhu ndeaya anotevera: 20 s: Yepakutanga kudzvanywa kwevhavha yekudzora kugadzikana yakabuda. 30 s: Ku "V" mhando notched mbiri yechigaro vharafu uye imwe chigaro vharafu yezvigadzirwa V-mhando inodzora bhora vharafu yakabuda. 1940s: Kubuda kwenzvimbo, mhando nyowani dzekudzora mavharuvhu anogadzirwazve, diaphragm valve, Angle valve, butterfly valve, bhora vharafu zvichingodaro. 1950s: Bharuvha yebhora yakashandiswa zvakanyanya, nzira nhatu-vharuvhu panzvimbo yevharuvhu yechigaro chimwe chete muhurongwa. 1960s: Mushure mekuvandudzwa kwakarongeka uye kumisikidzwa kwezvigadzirwa zviri pamusoro muChina, nhevedzano yezvigadzirwa yakagadzirwa muChina. Iye zvino tichiri mukushandiswa kwenhamba huru yevharuvhu yechigaro chimwe chete, vharuvhu yezvigaro zviviri, Angle vharafu, nzira nhatu vharafu, diaphragm vharafu, butterfly vharafu, bhora vharafu zvinomwe zvigadzirwa zvichiri nhanho yezvigadzirwa muma1960s. Panguva ino, vatorwa vakatanga kutangisa rudzi rwechisere rwechimiro chekudzora vharafu - sleeve valve. 70's: Chimwe chimiro chitsva chechigadzirwa - eccentric rotary valve yakabuda. Munguva iyi, mavharuvhu emaoko aishandiswa zvakanyanya kunze kwenyika. Mukupera kwema1970, dhizaini yemumba yakabatana yevharuvhu, kuitira kuti China ive neyayo mutsara wezvigadzirwa zvevharuvhu. 1980s: Munguva yekuvhura, China yakabudirira kuunza petrochemical mudziyo nekudzora tekinoroji yevharuvhu, kuitira kuti sleeve valve, eccentric rotary valve yave yakakurumbira uye kushandiswa, kunyanya sleeve valve, ine mukana wekutsiva imwe uye kaviri chigaro vharafu, kushandiswa kwayo kunowedzera uye kwakapararira. Pakupera kwe80's, regulator ndiyo kufambira mberi kukuru muJapan Cv3000 uye yakanaka diki regulator, ivo muchimiro, imwe chitubu pneumatic film actuator kuita multi-spring film actuator, iyo vharafu chimiro chakangovandudzwa, chisina kuchinjwa. Chinhu chayo chakatanhamara ndechekuti uremu uye kureba kwevhavha inodzika inodonha ne30%, uye kuyerera kwekofi kunowedzera ne30%. Mukuwedzera, kambani yedu inotengesa zvigadzirwa pamwe chete nekuzvimiririra kudzvinyirira kunodzora mavharuvhu, magetsi ega ega-seat regulating mavharuvhu uye zvichingodaro, kugamuchirwa kubvunza! Kuita kwakanakisa kwechigadzirwa, sevhisi ndeye yedu isinga peri-yekupedzisira, ndapota vatengi vatsva uye vekare vanovimbiswa kutenga zvavanoda zvigadzirwa. Gadzirisa valve kuti ikurumidze kubvisa zvikanganiso zvishanu zvinowanzopisa 1. Zvikanganiso zvinowanzoitika: kupisa hakusi kupisa zvachose. Kubvisa nzira: Vhura iyo inopinza uye dzosera vharafu yemvura. 2. Kukanganisa kwakajairika: kupisa hakusi kupisa (vhavha yakavhurwa). Kupisa hakusi hafu inopisa. Pane ruzha rwemvura mumudziyo wekudziya. Nzira yekubvisa: Panogona kunge paine gasi mune yekudziya system, uye inoda kudzikiswa. Method 1: Vhara vharuvhu yekupinza mvura kutanga. Vhura chivharo chekupedza, mvura inoputika, vharavhavha yekupedza. Nzira yechipiri: Vhara vharuvhu yekupinda ne 3/4, wozovhara vharafu yemvura yekudzoka, vhura vheji kuti upedze, uye hafu yevhavhavhavha yekuburitsa kana paine mvura yakawandisa. Yeuchidzai: Mushure mekushanda, kana kukanganisa kuchiri kutadza kubviswa, zivisa vashandi vekuchengetedza. 3. Kukanganisa kwakajairika: Kupisa kwepombi yekupisa hakuna kukwana, tembiricha yekamuri yakaderera. Nzira yekubvisa: Kana tembiricha yekupinza yakadzikira, wedzera tembiricha yekupinza. Inspection system by property. 4. Kukanganisa kwakajairika: Mvura inopinza uye mavharuvhu ekudzoka anodonhedza mukati (pedyo nehurongwa hwekudziya). Nzira yekubvisa: Vhara iyo inopinza uye dzorera mvura valve. Zivisai timu yekuisa kuti igadziriswe. 5. Zvikanganiso zvinowanzoitika: Kubuda kwemvura kunze kwekupinza uye mavharuvhu ekudzoka (pedyo nemugwagwa mukuru). Kubvisa nzira: zivisa pfuma hafu yakavharwa system valve; Zivisai timu yekuisa kuti igadziriswe.
