Butterfly valve , iyo inozivikanwawo sevhavhavhavha, ivharuvhu yekudzora iri nyore. Panguva imwecheteyo, inogona zvakare kushandiswa kushandura kudzora kwepasi-kumanikidza pombi yepakati. Butterfly valve ivharuvhu inovhara (disc kana disc) idhisiki uye inotenderedza vharafu kuti ivhure nekuvhara. Iyo inonyanya kutamba basa rekucheka-kubvisa uye throttling pane pombi. Iyo yekuvhura uye yekuvhara chikamu chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhaidhidhidhidhidhidhidhi,inotenderera ichitenderedza axis yayo mumutumbi wevharuvhu, kuitira kuti iwane chinangwa chekuvhura, kuvhara kana kugadzirisa. Butterfly vharafu inoshanda kune mapaipi anotakura akasiyana corrosive uye asiri corrosive fluid media muinjiniya masisitimu akadai sejenareta, gasi, gasi rechisikigo, liquefied petroleum gasi, gasi remudhorobha, mhepo inopisa uye inotonhora, kunyunguduka kwemakemikari, kugadzirwa kwemagetsi uye kuchengetedza kwezvakatipoteredza, uye inoshandiswa. kudzora nekucheka mafambiro enhau.
Kushandiswa kwevhavhavhavhavha
Butterfly mavharuvhu akakodzera kuyerera kwemutemo. Sezvo kupera simba kwevharuvhu yeshavishavi mupombi yakakura, inopeta katatu pane yevharuvhu yegedhi, pakusarudza vharuvhu yeshavishavi, kukanganiswa kwekurasikirwa kwepombi yepombi kunofanirwa kutariswa zvizere, uye kusimba kwepaipi ine butterfly plate. kudzvanywa kwepakati kana uchivhara kunofanirawo kutariswa. Uye zvakare, iyo yekushanda tembiricha muganho we elastic chigaro zvinhu pane yakanyanya tembiricha inofanirwa kutariswa.
Ivhavhavhavhavha ine hurefu hwechimiro uye kureba kwese, kukurumidza kuvhura uye kuvhara kumhanya, uye yakanaka yekudzora mvura maitiro. Nheyo yemaitiro evhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ndiyo inonyanya kukodzera kugadzira mavharuvhu makuru. Kana iyo butterfly valve ichidikanwa kudzora kuyerera, chinhu chinonyanya kukosha ndechokusarudza nemazvo ukuru uye rudzi rwevhavhavhavhavha kuitira kuti ishande nemazvo uye zvinobudirira.
Kazhinji, mukupuruzira, kudzora uye kutonga uye matope epakati, pfupi chimiro urefu uye nekukurumidza kuvhura uye kuvhara kumhanya (1 / 4R) inodiwa. Low pressure cut-off valve (diki differential pressure), butterfly valve inokurudzirwa.
Butterfly valve inogona kushandiswa muchiteshi ine kaviri chinzvimbo mutemo uye mutsipa, yakaderera ruzha, cavitation uye gasification, shoma shoma yekudonha kumhepo uye abrasive medium.
Kana iyo butterfly vharafu inoshandiswa pasi pemamiriro ekushanda akakosha, senge throttling regulation, chisimbiso chakasimba kana kupfeka kwakakomba, tembiricha yakaderera (cryogenic) uye mamwe mamiriro ekushanda, zvinodikanwa kushandisa yakakosha matatu eccentric kana maviri eccentric butterfly valve ine simbi yakagadzirwa. chisimbiso uye kudzora mudziyo.
The midline butterfly valveinoshanda kumvura yakachena, tsvina, mvura yegungwa, brine, steam, gasi rechisikigo, chikafu, mushonga, zvigadzirwa zveoiri, akasiyana acid uye alkali uye mamwe mapaipi anoda kuiswa chisimbiso chakakwana, zero gasi bvunzo kuvuza, hupenyu hwesevhisi yepamusoro uye tembiricha yekushanda ye-10 ~ 150 ¡æ.
Soft seal eccentric butterfly valve inokodzera kuvhurika-nzira mbiri, kuvhara uye kugadzirisa kwemhepo uye guruva rekubvisa pombi. Inoshandiswa zvakanyanya mumapombi egasi uye nzira yemvura yesimbi, indasitiri yemwenje, simba remagetsi uye petrochemical system.
Simbi kusvika kusimbi waya yakavharwa kaviri eccentric butterfly valveinokodzera kupihwa kupisa kwemaguta, kugovera chiutsi, mvura, gasi, oiri, asidhi uye alkali uye mamwe mapaipi sekudzora uye kuvharira michina.
Pamusoro pekushandiswa sechirongwa chekudzora vharafu yehombe yekumanikidza swing adsorption (PSA) gasi rekuparadzanisa unit, iyo simbi kunesimbi yakavharwa katatu eccentric butterfly valve inogona zvakare kushandiswa zvakanyanya mu petroleum, petrochemical, makemikari, simbi, magetsi emagetsi uye mamwe minda. Iyo yakanaka inotsiva yegedhi vharafu uye yekumisa vharafu
Kusarudzwa nheyo yevhavhavhavhavha
1. Nemhaka yekuti kuparara kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhevhavhavhavhavhavha kwehushavi kwakakura zvichienzaniswa nevharuvhu yegedhi,yakakodzera pombi system ine lax pressure kurasikirwa zvinodiwa.
2. Sezvo butterfly valve inogona kugadziriswa nekuyerera, yakakodzera kusarudzwa mupombi inoda kugadziriswa kwekuyerera.
3. Nekuda kwekuganhurirwa kweiyo butterfly valve chimiro uye yekuisa chisimbiso zvinhu, haikodzeri tembiricha yepamusoro uye yakanyanya kudzvanywa pombi system. Iyo yakawanda yekushanda tembiricha iri pazasi 300 ¡æ uye dzvinyiriro yezita iri pazasi PN40.
4. Sezvo butterfly valve ine hurefu hwekugadzirisa hurefu uye inogona kuitwa muhupamhi hukuru, inofanira kusarudzwa kune dzimwe nguva apo hurefu hwemaitiro hunodiwa hupfupi kana kuti mavharuvhu makuru (akadai sepamusoro peDN1000).
5. Sezvo vharuvhu ye butterfly inogona kuvhurwa kana kuvharwa chete nekutenderera 90 ¡ã, zvakakodzera kusarudza butterfly valve mumunda nekukurumidza kuvhura uye kuvhara zvinodiwa.
