Parizvino, thebutterfly valvechinhu chinoshandiswa kuona on-off uye kuyerera kutonga kwepombi system.
Yakave yakashandiswa zvakanyanya muminda yakawanda senge peturu, indasitiri yemakemikari, simbi, hydropower uye zvichingodaro.Mune inozivikanwa butterfly valve tekinoroji, chimiro chayo chekuisa chisimbiso chinonyanya kutora chimiro chekuisa chisimbiso,
Iyo yekuisa chisimbiso irabha, polytetraoxyethylene, etc. Nekuda kwekushomeka kwemaitiro ezvimiro, haina kukodzera kune maindasitiri akadai seyepamusoro tembiricha yekudzivirira, kukwirira kupikisa, kushomeka kwecorrosion, uye kusapfeka.
Ivharuvhu yeshavishavi iripo yakasimukira ivharuru ine eccentric simbi yakaoma-yakavharwa shavishavi.Muviri wakafara uye chigaro chevharuvhu zvakabatana, uye chisimbiso chepamusoro chechigaro chevharuvhu chakashongedzwa nezvinhu zvinodzivirira tembiricha uye corrosion-resistant alloy materials.
Iyo yakawanda-layer soft laminated sealing ring inogadzikwa paplate yevharuvhu.Kana ichienzaniswa neyakajairwa shavivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhahu iyi,ine tembiricha kuramba tembiricha, nyore kushanda, uye haina friction pakuvhura nekuvhara.Kana uchivhara, torque yemuchina wekutapurirana inowedzera kubhadharira chisimbiso.
Kuvandudza kushanda kwekuvhara kwevhavhavhavhavha uye zvakanakira kuwedzera hupenyu hwebasa.
Zvisinei, iyi butterfly valve ichine matambudziko anotevera panguva yekushandiswa
Sezvo iyo yakawanda-layer yakapfava uye yakaoma laminated yekuisa chisimbiso mhete yakagadzikwa pane yakafara ndiro, kana ndiro yevharuvhu ichiwanzo kuvhurika, iyo yepakati inoumba yakanaka scouring panzvimbo yayo yekuisa chisimbiso, uye iyo yakapfava yekuisa chisimbiso bhendi musimbi simbi sandwich ichaita zvakananga. kukanganisa kushanda kwekuisa chisimbiso mushure mekukweshwa.
Zvishoma nemamiriro ekugadzirisa, chimiro ichi hachina kukodzera mavharuvhu ane dhayamita pazasi DN200, nekuti iyo yakazara chimiro cheplate yevhavha yakanyanya kukora uye kuyerera kwekudzivirira kwakakura.
Nekuda kweiyo musimboti weiyo katatu eccentric chimiro, chisimbiso pakati pechisimbiso chepamusoro pevhavha ndiro uye chigaro chevharuvhu chinotsamira pane torque yechishandiso chekufambisa kudzvanya ndiro yakafara pachigaro chevharuvhu.Mune iyo yakanaka yekuyerera mamiriro, iyo yakakwirira iyo yepakati kudzvanywa, iyo inoomesa yekuisa chisimbiso extrusion.
Kana iyo inoyerera chiteshi chepakati ichiyerera ichidzokera shure, sezvo kumanikidza kwepakati kunowedzera, iyo unit yakanaka kudzvanywa pakati pevharuvhu ndiro uye chigaro chevharuvhu ishoma pane yepakati pressure, chisimbiso chinotanga kudonha.
Iyo yemhando yepamusoro yetatu-eccentric mbiri-yakaomarara sealing butterfly vharuvhu inoratidzwa mukuti chigaro chakafara chekuvharisa mhete inoumbwa nemateya akawanda emapepa esimbi isina tsvina pamativi ese emhete yakapfava yakaumbwa neT.Iyo yekuvharisa pamusoro peiyo slab uye chigaro chevharuvhu ndeye oblique koni chimiro,
Iyo pamusoro peiyo oblique koni yeplate yevhavha yakashongedzwa nekushisa-inodzivirira uye corrosion-resistant alloy materials;chitubu chakagadziriswa pakati peplate yekumanikidza yemhete yekugadzirisa uye kugadzirisa bhoti yeplate yekumanikidza inoungana pamwechete.
Ichi chimiro chinogadzirisa zvinogadzirisa nzvimbo yekushivirira pakati peshaft sleeve uye muviri wevharuvhu uye elastic deformation yetsvimbo yakafara pasi pekumanikidzwa kwepakati, uye inogadzirisa dambudziko rekuisa chisimbiso chevhavha munzira mbiri-inochinja-chinja yepakati nzira yekufambisa.
Mhete yekuisa chisimbiso inoumbwa neakapfava T-yakaita akawanda-layer simbi isina tsvina pamativi ese, ine mabhenefiti maviri esimbi yakaoma chisimbiso uye chisimbiso chakapfava, uye ine chisimbiso chekuvhara zero kudonha zvisinei nekudzika kwakadzika uye yakakwirira. tembiricha.
Muedzo unoratidza kuti kana dziva riri munzvimbo yakanaka yekuyerera (kuyerera kwepakati kwakafanana nekutenderera kutenderera kweplate yeshavishavi), kudzvanywa kuri pachisimbiso kunogadzirwa ne torque yechishandiso chekufambisa uye chiito chekumanikidza kwepakati pavhavha ndiro.
Kana iyo yakanaka yepakati pressure ichiwedzera, iyo yakaomesesa iyo oblique cone pamusoro peplate yevharuvhu uye yekuvharisa pamusoro pechigaro chevharuvhu inotsikirirwa, zvirinani kuita chisimbiso.Mune reverse kuyerera mamiriro, chisimbiso pakati pevharuvhu ndiro uye chigaro chevharuvhu zvinoenderana ne torque yechishandiso chekutyaira kudzvanya ndiro yevharuvhu pachigaro chevharuvhu.
Nekuwedzera kwereverse medium pressure, apo unit positive pressure pakati peplate yevharuvhu nechigaro chevharuvhu iri pasi pepakati pekumanikidza,
Iyo yakachengetwa deformation simba rechitubu chekugadzirisa mhete mushure mekuremerwa inogona kutsiva kuomeswa kwakasimba kwechisimbiso chepamusoro peplate yevharuvhu uye chigaro chevharuvhu kuti chingoripira.
Naizvozvo, kusiyana nehunyanzvi hwekutanga, iyo utility modhi haiisi yakaoma yakawanda-layer sealing ring paplate yevharuvhu, asi inoiisa zvakananga pane iyo valve body.Kuwedzerwa kwechindori chekugadzirisa pakati peplate yekumanikidza uye chigaro chevharuvhu ndiyo yakanakisa nzira mbiri-yakaoma yekuisa chisimbiso..
Inogona kutsiva mavharuvhu egedhi, mavharuvhu epasi uye mavharuvhu epasi.
