Musiyano uripo muchimiro chevharuvhu remapuruguru unosiyanisa marudzi mana emavharuvhu emapuruguru, anoti:vharuvhu yeshavishavi yakakombama, vharuvhu imwe chete isina kusimba yeshavishavi,vharuvhu yeshavishavi ine eccentric mbiriuye vharuvhu remashavishavi rine mativi matatu. Chii chinonzi eccentricness iyi? Ungasarudza sei kuti woshandisa riini concentric butterfly valve, kuti woshandisa riini single eccentric butterfly valve, kuti woshandisa riini double eccentric butterfly valve uye triple eccentric butterfly valve? Vazhinji vashandisi havana kunyatsojeka. Ngatidzidzei pamwe chete.
Mavharuvhu eshavishavi akasimba, mavharuvhu eshavishavi rimwe chete risingachinjiki, mavirimavharuvhu eshavishavi asina kusimbauye mavharuvhu emabhatafura ane mavara matatu anoratidza maitiro ekuvhura nekuvhara nekushanda nesimba kushoma uye kusakara kushoma pamusoro pekuvhara. Nekuisa nzvimbo yeshaft inotenderera yeplate yevharuvhu yebhatafura, mamiriro ekuvhara nekuvhura kwevharuvhu yebhatafura anogona kuchinjwa. Pasi pemamiriro akafanana, torque yevharuvhu pakuvhura iri kuwedzera mukutevedzana. Kana vharuvhu yavhurwa, kona yekutenderera inodiwa kuti plate yevharuvhu iparadzane nechisimbiso idiki mukutevedzana.
Chimiro chevharuvhu remashavi rakakombama ndechekuti pakati petsinde revharuvhu, pakati peplate remashavi nepakati pemuviri wevharuvhu zviri panzvimbo imwe chete. Kazhinji, kana mavharuvhu emashavi emashavi akakombama achigona kushandiswa, anofanira kushandiswa zvakanyanya sezvinobvira. Nekuti mhando ye concentric haidi kushanda kwakanyanya kwekuvhara maererano nechimiro kana mashandiro, chigadzirwa chemazuva ano. Kuti ikunde kubuda, kukwenya, uye kuve nechokwadi chekuti kushanda kwekuvhara, chigaro chevharuvhu chevharuvhu remashavi rakakombama chakagadzirwa nerabha kana PTFE nezvimwe zvinhu zvinonamira, inova vharuvhu remashavi rakapfava. Izvi zvinoita kuti kushandiswa kwemavharuvhu emashavi emashavi emashavi kuve pasi pemiganhu yekupisa. Kuti tigadzirise dambudziko rekubvisa plate remashavi nechigaro chevharuvhu, vharuvhu rimwe chete remashavi emashavi rakagadzirwa. Chimiro charo ndechekuti pakati petsinde revharuvhu rinotsauka kubva pakati peplate remashavi.
Vharuvhu ine mativi maviri e eccentric butterfly ndiyo inonyanya kushandiswa. Chimiro chayo ndechekuti shaft centre ye valvu inotsauka kubva pakati pe plate ye butterfly nepakati pe valvu. Inotsauka kubva panzvimbo mbiri dzepakati, saka inonzi double eccentric butterfly. Mazhinji acho akavharirwa ne line sealed. Kana nzvimbo ye sealing yavharwa, pane kukweshana pakati pe disc plate ne valvu, uye sealing effect yakanaka kwazvo. Ine hunhu hwenzvimbo diki uye kumanikidzwa kwakasimba. Mushure mekunge valvu yavhurwa, plate ye butterfly inogona kubva pakarepo kubva pa valvu, izvo zvinobvisa zvakanyanya extrusion yakawandisa uye kukwesha pakati pe plate ne chigaro, zvinoderedza kure kwe resistance yekuvhura, kupfeka, uye zvinovandudza hupenyu hwe valvu seat.
Vharuvhu yeshavishavi ine mativi matatu ine mativi matatu ekunze zvichibva pavharuvhu yeshavishavi ine mativi maviri ekunze. Chimiro chevharuvhu yekuvhara haisi cone yakanaka, asi cone yakachekwa. Mazhinji acho isimba redaro pfupi uye chisimbiso chepamusoro. Mubato wesimbi wevharuvhu yeshavishavi ine mativi matatu ekunze ishavi rine mativi matatu. Zvikamu zviviri zveshavi zveshavi yeshavi ine mativi matatu zvakadzika, uye mutsetse wepakati weshavi yepakati unotsauka kubva kumucheto wemagumo maviri nedaro repakati, uye plate yeshavishavi yakaiswa pakati. pashavi. Chimiro chakadaro chekunze chinoita kuti plate yeshavishavi ive nechimiro chekunze kaviri kana yakavhurika zvizere, uye chimiro chimwe chete chekunze kana plate yeshavishavi yatendeukira kunzvimbo yakavharwa. Nekuda kwemhedzisiro yeshavi yekunze, kana yava pedyo nekuvhara, plate yeshavishavi inofamba daro ichipinda pamusoro pe sealing cone yechigaro chevhavishavi, uye plate yeshavishavi inoenderana ne sealing surface yechigaro chevhavishavi kuti iwane sealing performance yakavimbika. Izvi zvinogadzirisa kusawirirana kwekuti hard seal ine seal isina kunaka, uye soft seal ine sealing effect yakanaka asi haidziviriri kupisa kwakanyanya.
Nguva yekushandisa vharuvhu remashavishavi rakakombama, nguva yekusarudza vharuvhu remashavishavi rakakombama kaviri kana vharuvhu remashavishavi rakakombama katatu, zvinonyanya kuenderana nemamiriro ekushanda uye bhajeti.
