Pamusana pekupopotedzana kwakaderera pakati pezvisimbiso zvekuvhara panguva yekuzarura nekuvhara, kuvhara kwevhavha kunogara kwenguva refu uye ine urefu hudiki hwekuzarura.Haisi chete yakakodzera kune yepakati uye yakaderera kudzvanywa, asiwo yakakodzera kune yakanyanya kudzvanywa media.Kuvimba nekumanikidzwa kwechitsigiro chevhavha, nzvimbo yekuvhara ye disc uye nzvimbo yekuvhara yechigaro chevhavha yakanyatsobatanidzwa kudzivirira svikiro kuti rirege kuyerera, iyo inomanikidzirwa kuvhara valve.Kuti uenderane nekushandiswa kwezviitiko zvakasiyana-siyana, kune marudzi mana emavharuvhu anovhara ane mabasa akasiyana: vharafu inovhara-vharuvhu, yakananga inoyerera inovhara-vharuvhu, yakajairwa yekuvharisa-vharuvhu uye kona yekuvhara-vharuvhu.Ndeupi musiyano uripo pakati pavo?
1) Inopinza uye kubuda kwekona-mhando yekumisa vharafu iri pakona ye90 madhigirii.Iyo angle-mhando yekumisa vharafu inowanzoiswa pakona yepombi uye inogona kutsiva iyo pombi yekubatanidza pakona.
Mu-angle-type shut-off valve, mvura inoyerera inongoda kushandura nzira yaro kamwe chete, kuitira kuti kudonha kwemhepo kuburikidza nevhavha idiki kudarika yevhavhavha yakavharwa.
2) Mamiriro ezvimiro uye hunyanzvi hwekusarudza ye-direct-flow stop valve, yakananga-inoyerera inomira vharafu, angle yekumisa vharafu uye plunger valve ndiyo Y-mhando yekumisa vharafu.Nekona ye 45 madhigirii, dhigirii yekukuvadza kumamiriro ekuyerera idiki pane iyo yakajairwa kuvhara-kuvhavha mavharuvhu, saka iyo yekumanikidza kurasikirwa kuburikidza nevhavha zvakare inowirirana idiki.Zvinogona zvakare kutaurwa kuti pane kunenge kusisina kudonhedza kudonha kurasikirwa, uye zvakare idiki diki kudonhedza kudonha kurasikirwa kwemavharuvhu ese akavhara..
3) Plunger mhando yeglobe vharafu: Iyi mhando yevharuvhu yepasi ndeyekusiyana kweyakajairwa globe valve.Muvharuvhu iyi, dhisiki uye chigaro chevharuvhu zvinowanzogadzirwa zvichibva pane plunger musimboti.Iyo valve clack inokwenenzverwa kuitira kuti plunger uye hunde yevharuvhu zvibatanidzwe, uye kuvharika kunowanikwa ne maviri elastic sealing mhete dzakaiswa maoko pane plunger.Zvindori zviviri zvekuisa chisimbiso zvinopatsanurwa nerengi remaoko, uye rin'i yekuvharisa yakatenderedza plunger inodzvanywa zvakasimba nemutoro unoiswa pabhoneti nebhoneti nati.Iyo elastic yekuisa chisimbiso mhete inogona kutsiviwa uye inogona kugadzirwa nezvinhu zvakasiyana.Iyo valve inonyanya kushandiswa ku "kuvhurika" kana "kuvhara", asi yakashongedzerwa nemhando yakakosha yeplunger kana yakakosha collar.Kaviri vharafu chigaro chinomanikidza chiyero chakatwasuka-kuburikidza neplunger vharafu.Iyo plunger inogona kufamba ichikwira nekudzika mumarin'i ekumusoro uye ezasi ekuvharisa uye ruoko rwegwara.Sleeve yekutungamira inopiwa negomba rekumanikidza, uye kudzvanywa kwepakati kunogona kupinda mugomba rezasi regidhi sleeve kuburikidza negomba diki.Kuisa chisimbiso kunogona kuwanikwa nekaviri chisimbiso chepamusoro cheplunger uye mhete yekuisa chisimbiso kaviri mumuviri wevharuvhu, uye kuyerera kwakakura kunogona kupfuudzwa.Nekuda kwekuti plunger ipfupi, kuvhura nekuvhara kumhanya kwakakwira kupfuura iyo yenguva dzose plunger valve;iyo pressure balance yakatwasuka-kuburikidza neplunger valve , Iyo plunger haina mhango, uye makamuri ekumusoro neazasi ane maburi.Dzinde revharuvhu rakabatana nepamusoro pechisimbiso sleeve uye nati kuti ienzanise kudzvanywa mumakamuri ekumusoro neakadzika eplunger uye kuchengetedza kushanda nesimba pakuvhura nekuvhara.Zvisinei, hunde yevharuvhu inofanira kuva nechisimbiso chepamusoro uye chisimbiso chekutakura, uye kuzarura nekuvhara nekukurumidza kunononoka.

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
