Ama-valve e-butterfly asebenza kanjani?

I-valve yebhabhathaneuhlobo lwevalvu olusebenzisa ingxenye yokuvula nokuvala idiski ukuze lubuyisele cishe ama-90° ukuvula, ukuvala noma ukulungisa izinga lokugeleza kwe-medium. Ivalvu ye-Butterfly ayinayo nje kuphela isakhiwo esilula, usayizi omncane, isisindo esincane, ukusetshenziswa kwezinto eziphansi, usayizi omncane wokufaka, i-torque encane yokushayela, ukusebenza okulula nokusheshayo, kodwa futhi inomsebenzi omuhle wokulawula ukugeleza kanye nezici zokuvala, futhi ingenye yezinhlobo zamavalvu ezikhula ngokushesha eminyakeni eyishumi edlule. Amavalvu e-Butterfly asetshenziswa kabanzi. Izinhlobonhlobo kanye nenani lokusetshenziswa kwawo kuyaqhubeka nokukhula, futhi kuthuthukela ekushiseni okuphezulu, ukucindezela okuphezulu, ububanzi obukhulu, ukuqina okuphezulu, impilo ende, izici ezinhle kakhulu zokulawula, kanye nemisebenzi eminingi yevalvu eyodwa. Ukuthembeka kwayo kanye nezinye izinkomba zokusebenza kufinyelele ezingeni eliphezulu.

Ngokusebenzisa irabha yokwenziwa engamelana namakhemikhali ukuzeamavalvu ebhabhathane, ukusebenza kweamavalvu ebhabhathaneithuthukisiwe. Ngenxa yokuthi irabha yokwenziwa inezici zokumelana nokugqwala, ukumelana nokuguguleka, ukuzinza kobukhulu, ukuqina okuhle, ukwakheka okulula, izindleko eziphansi, njll., irabha yokwenziwa enezakhiwo ezahlukene ingakhethwa ngokuya ngezimfuneko ezahlukene zokusetshenziswa ukuze kuhlangatshezwane nezimo zokusebenza zeamavalvu ebhabhathane.

Ngenxa yokuthi i-polytetrafluoroethylene (PTFE) inokumelana okuqinile kokugqwala, ukusebenza okuzinzile, akulula ukuguga, i-coefficient ephansi yokungqubuzana, kulula ukuyibumba, ukuzinza kobukhulu, futhi ingathuthukisa izakhiwo zayo eziphelele ngokugcwalisa nokwengeza izinto ezifanele, izinto zokuvala i-butterfly valve ezinamandla angcono kanye ne-coefficient ephansi yokungqubuzana zingatholakala, futhi imikhawulo yerabha yokwenziwa iyanqotshwa, ngakho-ke izinto ze-polymeric ze-polymer ezimelelwe yi-PTFE nezinto zayo eziguquliwe zokugcwalisa zisetshenziswe kabanzi ku-butterfly valve, ukuze ukusebenza kwe-butterfly valve kuthuthukiswe kakhulu.Amavalvu ebhabhathaneNjengoba amazinga okushisa nokucindezela kubanzi, ukusebenza kokuvala okuthembekile kanye nokuphila isikhathi eside kwesevisi kuye kwenziwa.

Ukuze kuhlangatshezwane nezidingo zezicelo zezimboni ezifana nokushisa okuphezulu nokuphansi, ukuguguleka okunamandla, kanye nokuphila isikhathi eside, amavalvu e-butterfly e-metal seal athuthukiswe kakhulu. Ngokusetshenziswa kokumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala okunamandla, ukumelana nokuguguleka okunamandla, kanye nezinto ze-alloy ezinamandla aphezulu kumavalvu e-butterfly, amavalvu e-butterfly avaliwe ngensimbi asetshenziswe kabanzi emikhakheni yezimboni efana nokushisa okuphezulu nokuphansi, ukuguguleka okunamandla, kanye nokuphila isikhathi eside, kanye namavalvu e-butterfly anobubanzi obukhulu (9~750mm), umfutho ophezulu (42.0MPa) kanye nobubanzi bokushisa obubanzi (-196~606°C) avele, kangangokuthi ubuchwepheshe bamavalvu e-butterfly bufinyelele ezingeni elisha.

Uma ivalvu yebhabhathane ivuliwe ngokugcwele, inokumelana okuncane kokugeleza. Uma ukuvulwa kuphakathi kuka-15°~70°, ingasetshenziswa ukulawula ukugeleza okubucayi, ngakho-ke ukusetshenziswa kwevalvu yebhabhathane kuvame kakhulu emkhakheni wokulungiswa kobubanzi obukhulu.

Ngenxa yokunyakaza okusulwa kwepuleti le-butterfly valve, ama-valve amaningi e-butterfly angasetshenziswa kuma-media ane-slids ezilengayo. Kuye ngamandla esivalo, angasetshenziswa futhi kuma-media aphuphuthekile nangama-granular.

Ama-valve e-Butterfly afanelekela ukulawulwa kokugeleza kwamanzi. Ngenxa yokuthi ukulahlekelwa yingcindezi ye-valve ye-butterfly epayipini kukhulu kakhulu, cishe kuphindwe kathathu kune-valve yesango, lapho kukhethwa i-valve ye-butterfly, ithonya lokulahlekelwa yingcindezi yesistimu yepayipi kufanele licatshangelwe ngokugcwele, futhi amandla epuleti le-butterfly lokuthwala ingcindezi ye-medium yepayipi uma ivaliwe kufanele acatshangelwe. Ngaphezu kwalokho, imikhawulo yokushisa okusebenzayo lapho izinto zesihlalo se-elastomeric zingabhekana khona emazingeni okushisa aphezulu nayo kumele icatshangelwe.

Ivalvu yebhabhathane inobude obuncane bokwakha kanye nokuphakama okuphelele, isivinini sokuvula nokuvala esisheshayo, kanye nezici ezinhle zokulawula uketshezi. Isimiso sesakhiwo samavalvu ebhabhathane silungele kakhulu ukwenza amavalvu amakhulu. Uma kudingeka ivalvu yebhabhathane isetshenziswe ukulawula izinga lokugeleza, kubalulekile ukukhetha usayizi ofanele kanye nohlobo lwevalvu yebhabhathane ukuze isebenze kahle nangempumelelo.

Ngokuvamile, ekucindezelweni, ekulawulweni kwemithethonqubo kanye nasendaweni yodaka, ubude besakhiwo bufushane, isivinini sokuvula nokuvala siyashesha, futhi kudingeka ukunqunywa kwengcindezi ephansi (umehluko omncane wengcindezi), futhi kunconywa ivalvu yevemvane. Amavalvu evemvane angasetshenziswa uma kukhona ukulungiswa kwezindawo ezimbili, isiteshi sobubanzi obuncishisiwe, umsindo ophansi, ukugoba kanye nokuhwamuka, inani elincane lokuvuza emoyeni, kanye nemidiya ehlukumezayo. Ngaphansi kwezimo zokusebenza ezikhethekile, ukulungiswa kwe-throttling, noma ukuvala okuqinile, ukuguguleka okukhulu, izinga lokushisa eliphansi (i-cryogenic) kanye nezinye izimo zokusebenza.
