Mukugadzira kwemazuva ano, mavharuvhu, semidziyo yakakosha yekudzora mvura, inoita basa rinokosha. Kanabutterfly valves, gedhi mavharuvhu, kanacheki mavharuvhu, vanoita basa rakakosha mumaindasitiri akasiyana siyana. Magadzirirwo nekugadzirwa kwemavharuvhu aya anosanganisira hunyanzvi hwekuita uye kufambira mberi kwetekinoroji. Seri kwezvose izvi, vadzidzisi muindasitiri yevharuvhu ndivo musana wenhaka uye hunyanzvi. Havasi vaparadzi vezivo chete, asiwo vachengeti veumhizha.
Butterfly mavharuvhu, inozivikanwa nekugadzirwa kwayo kukareruka, kuyerera kwepamusoro, uye kushanda kwakanakisa kwekuvhara, inoshandiswa zvakanyanya mumaindasitiri akadai sepetroleum, kemikari engineering, uye simba remagetsi. Dhizaini nekugadzira kwavo zvinoda hwaro hwakasimba mune tekinoroji uye yakakura inoshanda ruzivo. Varairidzi veindasitiri yemavharuvhu vanopa ruzivo urwu kuvadzidzi kuburikidza nekuraira kwakarongeka, kurima zvizvarwa zvinotevedzana zvematarenda ehunyanzvi ehunyanzvi. Havangodzidzisi vadzidzi magadzirirwo nekugadzira mavharuvhu eshavishavi, asi zvakatonyanya kukosha, vanovadzidzisa manzwisisiro edzidziso dzakakosha senge fluid mechanics nesainzi yemidziyo, zvichivagonesa kuzvishandisa zviri nyore mumamiriro ezvinhu epasirese.
Mavharuvhu egedhimavharuvhu akajairika, anonyanya kushandiswa kuvhara kana kubatanidza zvinwiwa mumapaipi. Kunyange iri nyore muchimiro uye iri nyore kushanda, kugadzira kwavo kunoda zvakanyanya kusarudzwa kwezvinhu uye nemazvo. Mipiro yevadzidzisi veindasitiri yevharuvhu mundima iyi haigone kurerutswa. Kuburikidza nemaoko-pane murayiridzo, vanobvumira vadzidzi kuti vatore chikamu mugedhi rekugadzira valve, vachinzwisisa kukosha kwenhanho imwe neimwe. Uku kuunganidzwa kweruzivo runoshanda hakungokwidziri unyanzvi hunoshanda hwevadzidzi chete asiwo kunovaka hwaro hwakasimba hwebasa ravo remangwana.
Tarisa mavharuvhuzvinhu zvakakosha zvekudzivirira mvuraback-flow uye anoshandiswa zvakanyanya mukurapa kwemvura, kudziyisa, uye kupa gasi. Magadzirirwo uye kugadzirwa kwemavharuvhu echeki anosanganisira ruzivo kubva kune akawanda dzidziso, kusanganisira fluid dynamics uye mechanic dhizaini. Kuburikidza nemirayiridzo yemarudzi akasiyana-siyana, varairidzi muindasitiri yevharuvhu vanobatsira vadzidzi kugadzira hwaro hweruzivo rwakakwana, zvichivagonesa kugadzirisa matambudziko akaomarara emabasa avo emangwana.
Muindasitiri yevharuvhu, vadzidzisi havasi ivo cheteinopa yeruzivo asiwo vagari venhaka yeumhizha. Vanoshandisa ruzivo rwavo uye huchenjeri kurima zvizvarwa zvematarenda ekugadzira mavharuvhu, zvichibatsira mukusimudzira indasitiri yekugadzira yeChina. Izvo chaizvo nekuda kwekushanda nesimba kwevadzidzisi ava kuti indasitiri yevharuvhu inogona kuramba ichigadzira uye kufambisa kufambira mberi muindasitiri yekugadzira.
Munyika yanhasi yepasi rose, indasitiri yekugadzira yakatarisana nematambudziko asina kumboitika nemikana. Sechikamu chakakosha cheindasitiri yekugadzira, indasitiri yevharuvhu inofanirwa kuramba ichisimudzira kugona kwayo tekinoroji uye kugona kwekuvandudza. Kubudirira uku hakuparadzaniswe nekushanda nesimba uye kuzvipira kwevadzidzisi vedu. Tinofanira kubhadhara mutero kune ava vagari venhaka yeiyi mhizha uye kuvatenda nokuda kwemipiro yavo kune indasitiri yevhavha uye nyika yose yekugadzira.
Muchidimbu, kugadzirwa kwebutterfly valves, gedhi mavharuvhu,uyecheki mavharuvhuhaidi kwete tekinoroji yepamusoro chete asiwo mhizha dzakanakisa. Vadzidzisi vari muindasitiri yemavharuvhu ndivo manyuko esimba iri, uye nhamburiko dzavo nekuzvipira zvicharamba zvichikurudzira budiriro yakasimba yeindasitiri yekugadzira zvinhu munyika yangu.
